Abstract
Description
Technical Field
[0001] The utility model belongs to the technical design field of automobile exhaust systems, and in particular relates to an exhaust system hanging device. Background Art
[0002] Currently, the two-hole lifting lugs on the market usually use regular holes. The lifting lugs will rotate during the movement of the exhaust system, causing relative sliding in the axial direction of the hook column, resulting in insufficient restraint on the exhaust system. In order to restrain the rotation of the lifting lug itself, three-hole lifting lugs or lifting lugs with exoskeletons are usually used to restrain the rotation of the lifting lug itself. Among them, three-hole lifting lugs require a lot of space on the side of the vehicle body, and the material cost of the lifting lug itself will also increase. Single-hole lifting lugs composed of exoskeletons have greater rigidity, relatively average shock absorption, and are very expensive. The cost of two-hole lifting lugs is lower, but the structural characteristics of the two holes determine this. Summary of the Invention

[0043] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0044] The embodiment of the present invention provides an exhaust system hanging device, comprising:
[0045] The lifting ear body 1 includes a first hole 1a and a second hole 1b. The first hole 1a and / or the second hole 1b pass through the lifting ear body 1 along a first direction A. The first hole 1a and the second hole 1b are spaced apart along a second direction B. At least one limit block 2 is provided on the lifting ear body 1.
[0046] The hook assembly 3 comprises:
[0047] A hook column 31 extends along a first direction A, and one end of the hook column 31 passes through the first hole 1a;
[0048] A first pier head 32 is fixedly provided at one end of the hook column 31 and provided on one side of the lifting ear body 1;
[0049] The second pier head 34 is fixedly mounted on the hook column 31 and is provided on the other side of the lifting ear body 1;
[0050] At least one groove 33 is provided on the first pier head 32 and / or the second pier head 34. The number and position of the grooves 33 correspond to the number and position of the limit blocks 2. The limit blocks 2 are inserted into the grooves 33.
[0051] The cross-sectional area of the first pier head 32 near the first hole 1a is larger than the area of the first hole 1a; and / or the cross-sectional area of the second pier head 34 near the first hole 1a is larger than the area of the first hole 1a.
[0052] In a specific embodiment, Figure 1 and Figure 3 As shown, the upper portion of the ear body 1 is provided with the first hole 1a, and the lower portion is provided with the second hole 1b, the first hole 1a and the second hole 1b are spaced apart in the vertical direction. The first hole 1a is used to install the hook column 31, and the second hole 1b is used to connect to the exhaust system.
[0053] During operation, the exhaust system vibrates, driving the lifting ear body 1 to move in the up-down direction, and relative displacement also occurs between the lifting ear body 1 and the hook column 31 in the axial direction.
[0054] like Figure 1 As shown, the hook column 31 passes through the first hole 1a, the first pier head 32 on the left side is arranged on the left side of the lifting ear body 1, and the cross-sectional area of the right side of the first pier head 32 is larger than the area of the first hole 1a, and the second pier head 34 on the right side is arranged on the right side of the lifting ear body 1, and the cross-sectional area of the left side of the second pier head 34 is also larger than the area of the first hole 1a, so that the structure is stable and can slow down the relative displacement of the lifting ear body 1 and the hook column 31 in the axial direction.
[0055] The lifting lug body 1 is provided with the limiting block 2. Figure 2 As shown, for example, the limiting block 2 may be provided on the left side, the right side, or both the left and the right sides.
[0056] In a specific embodiment, the limiting block 2 is provided on the left side of the lifting ear body 2 , and the groove 33 is provided on the first pier head 32 .
[0057] In another specific embodiment, the limiting block 2 is provided on the right side of the lifting ear body 2 , and the groove 33 is provided on the second pier head 34 .
[0058] In another specific embodiment, Figure 1As shown, the limit blocks 2 are provided on the left and right sides of the lifting ear body 1, and accordingly, the grooves 33 are provided on the first pier head 32 and / or the second pier head 34, and the limit blocks 2 are stuck in the grooves 33, so that this structure can prevent the hook column 31 from rotating in the first hole 1a.
[0059] Furthermore, the material of the ear body 1 is rubber;
[0060] The cross-sectional area of the first pier head 32 gradually decreases from a side close to the lifting eye body 1 to a side away from the lifting eye body 1 .
[0061] like Figure 1 As shown, the cross-sectional area of the first pier head 32 gradually decreases from right to left and is tapered. During installation, since the ear body 1 is made of rubber and has elasticity, the installation can be completed by simply inserting the hook column 31 into the first hole 1a from right to left.
[0062] The number, position and shape of the limit blocks 2 and the grooves 33 in this application are not limited. In a specific embodiment, the limit blocks 2 include a first limit block 21;
[0063] The first pier head 32 and / or the second pier head 34 includes a first groove 331 , and the first limiting block 21 is tightly fitted in the first groove 331 .
[0064] In a specific embodiment, Figure 1 As shown, the first limit blocks 21 are provided on both sides of the lifting lug body 1, and the first pier head 32 and the second pier head 34 are both provided with the first groove 331. During operation, the exhaust system moves vertically, driving the lifting lug body 1 to move vertically. Because the first limit blocks 21 tightly fit the first groove 331, the hook column 31 can provide support for the lifting lug body 1, preventing the lifting lug body 1 from displacement or rotation.
[0065] The first limit block 21 can be arranged at any side of the first hole 1a. Furthermore, the first limit block 21 is arranged at the side of the first hole 1a away from the second hole 1b. Figure 3 As shown, this structure facilitates providing support force to the lifting ear body 1 .
[0066] Furthermore, the width of the first limiting block 21 gradually increases from an end close to the first hole 1 a to an end away from the first hole 1 a.
[0067] It can be understood that the shape of the first groove 331 should be the same as that of the first limit block 21, that is, the first limit block 21 and the first groove 331 are both inverted trapezoids. This structure is stable and ensures that the ear body 1 can bear a large weight.
[0068] Furthermore, the limit block 2 further includes:
[0069] a second limiting block 22 and a third limiting block 23, the second limiting block 22 and the third limiting block 23 being spaced apart along a third direction C, wherein the second limiting block 22 is provided on one side of the first hole 1a, and the third limiting block 23 is provided on the other side of the first hole 1a; the third direction C is perpendicular to the second direction B;
[0070] The first pier head 32 and / or the second pier head 34 further include:
[0071] A second groove 332, the second groove 332 corresponds to the position of the second limiting block 22 and is for the second limiting block 22 to be inserted;
[0072] The third groove 333 corresponds to the position of the third limiting block 23 and is for the third limiting block 23 to be inserted into.
[0073] In a specific embodiment, Figure 1 As shown, the second limiting block 22 and the third limiting block 23 are provided on both sides of the lifting ear body 1, and the first pier head 32 and the second pier head 34 are provided with the second groove 332 and the third groove 333. Figure 3 As shown, the left side of the first hole 1a is the second limit block 22, and the right side is the third limit block 23, wherein this structure can further support the ear body 1 and can prevent the hook column 31 from rotating in the first hole 1a.
[0074] Furthermore, the side of the second limiting block 22 facing away from the second hole 1b is in contact with the inner wall of the second groove 332, and a gap is provided between the side of the second limiting block 22 close to the second hole 1b and the inner wall of the second groove 332;
[0075] And / or, the side of the third limiting block 23 away from the second hole 1b is in contact with the inner wall of the third groove 333 , and a gap is provided between the side of the third limiting block 23 close to the second hole 1b and the inner wall of the third groove 333 .
[0076] like Figure 1 、 Figure 3 Figure 4As shown, the upper side of the second limit block 22 is in contact with the inner wall of the second groove 332, and the upper side of the third limit block 23 is in contact with the inner wall of the third groove 333. When the ear body 1 is under pressure, the second limit block 22 and the third limit block 23 can support the ear body 1, which is conducive to providing better fixing force.
[0077] Furthermore, the first pier head 32 and / or the second pier head 34 further includes a fourth groove 334;
[0078] The limiting block 2 further includes a fourth limiting block 24, which is disposed on a side of the first hole 1a away from the first limiting block 21 and in the fourth groove 334;
[0079] Along the third direction C, a gap is provided between any side of the fourth limiting block 24 and the inner wall of the fourth groove 334 .
[0080] In a specific embodiment, Figure 1 As shown, both sides of the ear body 1 are provided with the fourth limit block 24, and both the first pier head 32 and the second pier head 34 are provided with the fourth groove 334. Figure 1 、 Figure 3 Figure 4 As shown, a gap is provided between the left side of the fourth limit block 24 and the left inner wall of the fourth groove 334, and a gap is also provided between the right side of the fourth limit block 24 and the right inner wall of the fourth groove 334. When the ear body 1 is deformed, this structure is beneficial to the rebound of the ear body 1, avoiding the ear body 1 from getting stuck during deformation or rebound, and is also beneficial for the limit block 2 to return to the groove 33.
[0081] Furthermore, the width of the second limiting block 22 gradually increases from the end close to the first hole 1a to the end away from the first hole 1a;
[0082] And / or, the width of the third limiting block 23 gradually increases from an end close to the first hole 1a to an end away from the first hole 1a;
[0083] And / or, the width of the fourth limiting block 24 gradually increases from an end close to the first hole 1 a to an end away from the first hole 1 a.
[0084] like Figure 3 As shown, the second limit block 22, the third limit block 23, and the fourth limit block 24 are all designed in a trapezoidal structure, which matches the movement path of the ear body 1 during vibration pulling. While limiting the rotation of the hook column 31, it does not hinder the pulling movement of the ear body 1 in the vertical direction.
[0085] Furthermore, a slope section 341 is provided on the side of the second pier head 34 close to the lifting eye body 1.
[0086] The cross-sectional area of the slope section 341 gradually decreases from a side away from the lifting eye body 1 to a side close to the lifting eye body 1 .
[0087] like Figure 4 As shown, the left side of the second pier head 34 is the slope section 341, and the cross-sectional area of the slope section 341 gradually decreases from right to left, so that the contact between the left side of the second pier head 34 and the right side of the ear body 1 is line contact. This structure can avoid abnormal noise caused by violent collision between the hook column 31 and the ear body 1 when the hook column 31 is displaced axially.
[0088] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to examples, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
