Description

Technical Field

[0001] This utility model relates to a sealing structure, specifically a novel vehicle wheel rim sealing structure, belonging to the field of wheel hub structure technology. Background Technology

[0002] The rim is a crucial component on the outer surface of the wheel hub, directly contacting the tire and securing its position. For tubeless tires, the tire bead is typically inserted into the rim rim. During inflation, the hump within the rim then engages with the tire surface to ensure relative fixation. However, because the hump occupies space within the rim rim, inserting the tire bead is difficult, easily resulting in incomplete insertion. This leads to insufficient contact between the hump and the tire bead during inflation, causing relative movement between the tire and the rim. Therefore, a rim design that facilitates tire installation is needed. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a new type of vehicle wheel rim sealing structure, which has a simple and reasonable structure, stable tire installation, and saves time and effort during installation.

[0004] The technical solution adopted by this utility model is as follows: a novel vehicle wheel rim sealing structure, including a left rim body and a right rim body; the outer edges of the left rim body and the right rim body are respectively provided with wheel flanges, and the left rim body and the right rim body are respectively provided with a plurality of through holes; each of the through holes is provided with a movable hump; a locking mechanism is also provided between the left rim body and the right rim body.

[0005] Furthermore, the through hole has a first opening on the end face of the left rim and the right rim on opposite sides; the through hole has a second opening inside the rim of the left rim and the right rim.

[0006] Furthermore, a push rod is provided inside the through hole; a sliding protrusion is provided around the push rod; a guide groove is provided inside the through hole relative to the sliding protrusion; the sliding protrusion is slidably disposed in the guide groove; a spring is provided in the guide groove and is connected to the sliding protrusion.

[0007] Furthermore, the movable hump is located at the end of the top rod; the outline dimensions of the second opening are consistent with those of the movable hump.

[0008] Furthermore, a core plate is provided on the inner side of the left rim and the right rim respectively; the locking mechanism is provided on the core plate.

[0009] Furthermore, a central hole is provided at the center of the central plate; the locking mechanism includes screw holes provided around the central hole.

[0010] Furthermore, each of the aforementioned spindle plates includes three screw holes; the screw holes on each of the aforementioned spindle plates correspond one-to-one.

[0011] This invention offers the following advantages: The rim is divided into a left rim body and a right rim body, each with its own flange. First, the tire bead on one side is inserted into the left rim body. At this point, because the movable hump is retracted within the through hole, it does not occupy space within the flange, facilitating tire bead insertion. After the tire beads on both sides are inserted into the left and right rim bodies respectively, the left and right rim bodies are then closed and fixed. During this closing process, the interaction force between the two forces causes the movable hump to move outward from the through hole and into the flange, actively compressing the tire bead. Inflating the tire under these conditions further ensures a tighter contact between the tire bead and the hump. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] See Figures 1-3 This application discloses a novel vehicle wheel rim sealing structure, including a left rim body 1 and a right rim body 2; the outer edges of the left rim body 1 and the right rim body 2 are respectively provided with wheel flanges 3, and a plurality of through holes 4 are respectively provided on the left rim body 1 and the right rim body 2; each of the through holes is provided with a movable hump 5; a locking mechanism is also provided between the left rim body 1 and the right rim body 2.

[0018] Furthermore, the through hole 4 has a first opening on the end face of the left rim body 1 and the right rim body 2 on opposite sides; the through hole 4 has a second opening in the rim 3 of the left rim body 1 and the right rim body 2.

[0019] Furthermore, a push rod 7 is provided inside the through hole 4; a sliding protrusion 51 is provided around the push rod 7; a guide groove 41 is provided inside the through hole 4 relative to the sliding protrusion 51; the sliding protrusion 51 is slidably disposed in the guide groove 41; a spring 6 is provided in the guide groove 41 and is connected to the sliding protrusion 51.

[0020] Furthermore, the movable hump 5 is located at the end of the top rod 7; the outline dimensions of the second opening are consistent with those of the movable hump 5.

[0021] Furthermore, the inner sides of the left rim body 1 and the right rim body 2 are respectively provided with a core plate 8; the locking mechanism is provided on the core plate 8.

[0022] Furthermore, the spindle plate 8 has a spindle hole 81 at its center; the locking mechanism includes screw holes around the spindle hole 81.

[0023] Furthermore, each of the aforementioned spindle plates includes three screw holes; the screw holes on each of the aforementioned spindle plates correspond one-to-one.

[0024] Working principle: First, insert one side of the tire bead into the rim 3 of the left rim 1, ensuring proper insertion. Then, insert the other side of the tire bead into the rim 3 of the right rim 2, so that both tire beads are supported by their respective rims 3. Next, close and fix the left rim 1 and right rim 2 together. During the closing process, the push rods 7 on the left rim 1 and right rim 2 will generate an interaction force, pushing each other and causing the push rods 7 to translate through the through hole 4. Ultimately, the movable hump 5 at the end of the push rod 7 moves from the through hole into the rim 3 and directly contacts the tire bead, creating a tight compression. In this situation, when the tire is inflated, the tire bead can better cover the movable hump 5, achieving a better coupling connection.
