Description

Technical Field

[0001] The invention belongs to the field of automobile tire blowout emergency devices, and in particular relates to a support belt anti-detachment and blocking support bead and a tire blowout emergency safety device. Background Art

[0002] When the tire pressure of a vehicle is lower than the standard value or the tire is damaged and leaks, the friction between the deflated tire and the ground will increase exponentially, causing the tire temperature to rise sharply, the tire to soften, and the strength to drop sharply. In this case, if the vehicle is traveling at high speed, it may cause a tire blowout; if a tire of the vehicle blows out, it will cause the vehicle to deviate. If the driver cannot respond correctly, the vehicle will overturn and hit the guardrail, causing danger, and may even collide with vehicles in the same direction or the opposite direction, causing huge personal injury or property loss. The prior art discloses a tire blowout emergency safety device, which limits the tire position by fastening a support belt on the wheel hub, and can prevent the tire from detaching after a tire blowout to avoid loss of control.

[0003] The support belt is generally made of metal, with bending tongues at both ends, which are bent inward to form a bent portion, and two or more bent portions are connected by a connector to achieve fastening. However, the inward bending structures at both ends of the support belt of the tire blowout safety emergency device are in contact with the wheel hub. When a tire blows, the bent portion is subjected to huge tensile and impact forces, and may be straightened or flattened, which may cause the support belt to detach and fail.

[0004] Therefore, there is an urgent need for a blocking support member that can protect the inwardly bent structures at both ends of the support belt from deforming when a tire blows out, so as to prevent the support belts from separating from each other. Summary of the invention

[0005] The object of the present invention is to provide a blocking support member that can protect the inwardly bent structures at both ends of the support belt from deforming when a tire blows out, thereby preventing the support belts from detaching from each other. The invention content is as follows:

[0006] A support bead for preventing a support belt from falling off and blocking includes a main body having a groove for accommodating a bending tongue of the support belt, wherein the groove divides the main body into an anti-slip and anti-falling part for padding between the bending tongue of the support belt and a hub and a supporting part for filling the bending part of the support belt.

[0007] Furthermore, the anti-slip and anti-slip portion is provided with an opening for reducing the elastic force of the anti-slip and anti-slip portion.

[0008] Furthermore, the opening is U-shaped and forms a corresponding U-shaped spring piece, the U-shaped spring piece is provided with a protrusion away from the wheel hub side, the top surface of the protrusion is provided with an inclination angle, and the support belt bending tongue is preset with a limiting hole; the limiting hole cooperates with the protrusion and is used for limiting the installation between the blocking support bead and the support belt bending tongue.

[0009] Furthermore, the support portion is provided with a through limiting groove, and the limiting groove is used to place a connecting piece between the support belt and another support belt.

[0010] Furthermore, the blocking support beads are made of elastic material.

[0011] Furthermore, the blocking support beads are made of polypropylene.

[0012] Furthermore, the body is wedge-shaped.

[0013] A tire blowout emergency safety device comprises any one of the above-mentioned blocking support beads.

[0014] The present invention has the following beneficial effects:

[0015] ① The blocking support beads provided by the present invention can prevent the inward bending structures at both ends of the tire protection support belt from deforming when a tire blows out, prevent the support belt from loosening or detaching from another support belt, and ensure that the tire blowout emergency device always has a protective effect.

[0016] ② The blocking support beads provided by the present invention can support the inwardly bent structures at both ends of the support belt, thereby preventing the support belt from being deformed and causing uneven force when a tire blows out.

[0017] ③The blocking support beads provided by the present invention have a simple structure and are easy to install.

[0018] ④ The blocking support beads provided by the present invention can place electronic products such as tire pressure detection, GPS positioning, thermometer, oil tank, loose alarm or tire blowout alarm inside the blocking support beads, which can protect the electronic products from being crushed; at the same time, the joints on both sides of the steel belt are usually empty, and there is resonance when the car is running. The blocking support beads provided by the present invention can absorb the resonance. BRIEF DESCRIPTION OF THE DRAWINGS
