Description
Technical Field
[0001] The utility model relates to the technical field of automobile parts, in particular to a vehicle buffer part. Background Art
[0002] With improved living standards and increasingly diverse vehicle features, people are demanding higher quality and a more comfortable driving experience. To mitigate direct axle impact on the vehicle frame or body, reduce driving noise, and enhance driving comfort, buffers are often installed in areas such as the engine compartment, trunk, and body sides. However, existing buffers can easily produce unusual noises during driving, impacting vehicle quality and the overall driving experience. Utility Model Content
[0003] In order to improve the quality and driving experience of a car, the utility model proposes a vehicle buffer component, which includes a buffer sleeve and a sheet metal ring. The outer wall of the buffer sleeve is provided with a clamping convex ring, a clamping clamping convex and a positioning convex ridge. The clamping convex ring and the clamping clamping convex are arranged opposite to each other in the middle of the buffer sleeve and form an annular clamping groove. The positioning convex ridge is located in the annular clamping groove, and the extension direction of the positioning convex ridge is parallel to the central axis of the buffer sleeve; at least two clamping convexes are provided on the inner side of the sheet metal ring, the sheet metal ring is installed in the annular clamping groove and is clamped with the clamping clamping convex through the clamping convex, and the inner edge of at least one of the clamping convex is tightly against the positioning convex ridge. In the vehicle buffer of the present invention, a clamping convex ring and a clamping convex are provided on the outer wall of the buffer sleeve to form an annular clamping groove for mounting the sheet metal collar. The positioning ridges provided on the outer wall of the buffer sleeve radially support the clamping ridges on the inner edge of the sheet metal collar, allowing the sheet metal collar to be tightly sleeved on the buffer sleeve. Thus, the vehicle buffer of the present invention utilizes the clamping convex ring, the clamping convex, and the positioning ridges on the outer wall of the buffer sleeve to position the sheet metal collar, thereby securing the sheet metal collar relative to the buffer sleeve. This improves the quality of the vehicle, prevents the sheet metal collar from shaking and producing unusual noises during vehicle operation, and enhances the driving experience.
[0004] Preferably, two positioning ridges are provided on the outer wall of the buffer sleeve, and the two positioning ridges are arranged opposite to each other. In this way, by providing two symmetrically arranged positioning ridges on the outer wall of the buffer sleeve, it is possible to ensure that the sheet metal collar is concentric with the buffer sleeve after being placed on the buffer sleeve, thereby avoiding the center of gravity shift of the vehicle buffer of the present invention and improving the quality of the car equipped with the vehicle buffer of the present invention. Furthermore, the outer edge of the positioning ridge is an arc-shaped surface. In this way, the outer edge of the positioning ridge is provided as an arc-shaped surface, which can increase the contact area between the outer edge of the positioning ridge and the sheet metal collar, improve the stability of the sheet metal collar on the buffer sleeve, and avoid the positioning ridge from damaging the inner edge of the sheet metal collar, thereby affecting the quality of the vehicle buffer of the present invention.
[0005] Preferably, a supporting protrusion is provided on the outer wall of the buffer sleeve, and the supporting protrusion is located between two adjacent clamping protrusions. The axial spacing between the supporting surface of the supporting protrusion and the clamping protrusion is smaller than the axial spacing between the engaging surface of the clamping protrusion and the clamping protrusion. In this way, after the sheet metal collar is placed on the buffer sleeve, the supporting protrusion and the clamping protrusion cooperate to clamp the sheet metal collar, thereby preventing the sheet metal collar from moving in the axial direction of the buffer sleeve due to vibration during driving, thereby generating abnormal noise and affecting the quality of the car and the driving experience.
[0006] Preferably, the bottom end of the buffer sleeve is provided with at least two clamping guards, and the clamping guards are connected to the bottom end of the buffer sleeve through a connecting block and enclose to form an annular clamping structure. When the vehicle buffer of the present invention is installed on the vehicle body using a quick-insert bolt joint, after the quick-insert bolt joint is installed in the buffer sleeve and threadedly connected to the buffer sleeve, the annular clamping structure formed by the clamping guards can be used to clamp the joint end of the quick-insert bolt joint. In this way, the annular clamping structure can be used to form a buffer portion to buffer the vibration transmitted to the vehicle buffer of the present invention by the vehicle body, reduce the vibration of the vehicle buffer of the present invention, thereby reducing the probability of abnormal noise caused by vibration of the vehicle buffer of the present invention during driving of the vehicle, and improving the quality of the vehicle and the driving experience. Furthermore, the clamping sides at both ends of the clamping guard are provided with anti-slip protrusions. In this way, after the quick-insert bolt connector and the vehicle buffer of the present invention are assembled together, the anti-slip protrusion on the clamping guard can be clamped into the axial groove on the outer wall of the connector end of the quick-insert bolt connector, thereby preventing the quick-insert bolt connector from being misaligned with the vehicle buffer of the present invention due to vibration during the driving of the car, or even causing the vehicle buffer of the present invention to fall off, affecting the quality of the car and the driving experience. Further preferably, the outer edge of the anti-slip protrusion is an arc-shaped curved surface. In this way, when the vehicle buffer of the present invention and the quick-insert bolt connector are assembled together, it is convenient to clamp the anti-slip protrusion into the axial groove on the quick-insert bolt connector, and it can also prevent the anti-slip protrusion from damaging the quick-insert bolt connector and affecting the installation of the vehicle buffer of the present invention.

[0010] Next, combine Figures 1 to 3 , the vehicle buffer component of the utility model is described in detail.
[0011] like Figures 1 to 3 As shown, the vehicle buffer of the utility model includes a buffer sleeve 1 and a sheet metal ring 2. A clamping convex ring 11, a clamping clamping convex 12 and a positioning convex rib 13 are provided on the outer wall of the buffer sleeve 1. The clamping convex ring 11 and the clamping clamping convex 12 are arranged opposite to each other in the middle part of the buffer sleeve 1 and form an annular clamping groove (not shown in the figure). The positioning rib 13 is located in the annular clamping groove, and the extension direction of the positioning rib 13 is parallel to the central axis of the buffer sleeve 1; at least two clamping ribs 21 are provided on the inner side of the sheet metal ring 2, the sheet metal ring 2 is installed in the annular clamping groove and is clamped with the clamping clamping rib 12 through the clamping rib 21, and the inner edge of at least one clamping rib 21 is tightly attached to the positioning rib 13. In the vehicle buffer of the present invention, a clamping convex ring 11 and a clamping clamping protrusion 12 are provided on the outer wall of the buffer sleeve 1 to form an annular clamping groove for mounting the sheet metal collar 2, and a positioning rib 13 provided on the outer wall of the buffer sleeve 1 is used to support the clamping protrusion 21 on the inner edge of the sheet metal collar 2 in the radial direction, so that the sheet metal collar 2 is tightly sleeved on the buffer sleeve 1. In this way, the vehicle buffer of the present invention uses the clamping convex ring 11, the clamping clamping protrusion 12 and the positioning rib 13 on the outer wall of the buffer sleeve 1 to position the sheet metal collar 2, so that the sheet metal collar 2 and the buffer sleeve 1 are relatively fixed, thereby improving the quality of the car and preventing the sheet metal collar 2 from shaking and producing abnormal noise during the driving of the car, thereby improving the driving experience of the car. Preferably, two positioning ribs 13 are provided on the outer wall of the buffer sleeve 1, and the two positioning ribs 13 are arranged opposite each other. In this way, two symmetrically arranged positioning ribs 13 are provided on the outer wall of the buffer sleeve 1, which can ensure that the sheet metal collar 2 is concentric with the buffer sleeve 1 after being placed on the buffer sleeve 1, thereby avoiding the center of gravity shift of the vehicle buffer of the present invention and improving the quality of the car equipped with the vehicle buffer of the present invention. Preferably, the outer edge of the positioning rib 13 (not shown in the figure) is an arc-shaped surface. In this way, the outer edge of the positioning rib 13 is set as an arc-shaped surface, which can increase the contact area between the outer edge of the positioning rib 13 and the sheet metal collar 2, improve the stability of the sheet metal collar 2 on the buffer sleeve 1, and avoid the positioning rib 13 from damaging the inner edge of the sheet metal collar 2, which affects the quality of the vehicle buffer of the present invention.
[0012] like Figures 1 to 3As shown, a supporting protrusion 14 is provided on the outer wall of the buffer sleeve 1, and the supporting protrusion 14 is located between two adjacent clamping protrusions 12, and the axial distance between the supporting surface (not shown in the figure) of the supporting protrusion 14 facing the clamping protrusion ring 11 and the clamping protrusion 11 is smaller than the axial distance between the clamping surface (not shown in the figure) of the clamping protrusion 12 facing the clamping protrusion 11 and the clamping protrusion 11. In this way, after the sheet metal collar 2 is sleeved on the buffer sleeve 1, the supporting protrusion 14 and the clamping protrusion 11 can be used to clamp the sheet metal collar 2, thereby preventing the sheet metal collar 2 from moving in the axial direction of the buffer sleeve 1 due to vibration during the driving of the car, thereby preventing abnormal noise from being generated, and affecting the quality of the car and the driving experience.
[0013] like Figures 1 to 3 As shown, the bottom end of the buffer sleeve 1 is provided with at least two clamping guards 15, and the clamping guards 15 are connected to the bottom end of the buffer sleeve 1 through the connecting block 16 and enclose to form an annular clamping structure (not shown in the figure). When the vehicle buffer of the utility model is installed on the vehicle body using the quick-insert bolt joint 3, after the quick-insert bolt joint 3 is installed in the buffer sleeve 1 and threadedly connected to the buffer sleeve 1, the annular clamping structure formed by the clamping guards 15 can be used to clamp the joint end of the quick-insert bolt joint 3. In this way, the annular clamping structure can be used to form a buffer portion to buffer the vibration transmitted to the vehicle buffer of the utility model from the vehicle body, reduce the vibration of the vehicle buffer of the utility model, thereby reducing the probability of abnormal noise caused by vibration of the vehicle buffer of the utility model during the driving of the car, and improving the quality of the car and the driving experience. Preferably, the clamping sides of the two ends of the clamping guard 15 are provided with anti-slip protrusions 151. In this way, after the quick-insert bolt connector 3 and the vehicle buffer of the present invention are assembled together, the anti-slip cam 151 on the clamping guard plate 15 can be clamped in the axial clamping groove 31 on the outer wall of the connector end of the quick-insert bolt connector 3, so as to prevent the quick-insert bolt connector 3 from being misaligned with the vehicle buffer of the present invention due to vibration during the driving of the car, or even causing the vehicle buffer of the present invention to fall off, affecting the quality of the car and the driving experience. Preferably, the outer edge of the anti-slip cam 151 (not marked in the figure) is an arc-shaped surface. In this way, when the vehicle buffer of the present invention and the quick-insert bolt connector 3 are assembled together, it is convenient for the anti-slip cam 151 to be clamped in the axial clamping groove 31 on the quick-insert bolt connector 3, and it can also prevent the anti-slip cam 151 from damaging the quick-insert bolt connector 3 and affecting the installation of the vehicle buffer of the present invention.
