Description

Technical Field

[0001] The utility model relates to the technical field of tire blowout protection devices, in particular to a centrifugal structure used for tire blowout protection devices. Background Art

[0002] Currently, tires produced by tire factories are components that come into direct contact with the road. They not only support the full weight of an object but also transmit the object's driving and braking forces to the road surface, thereby controlling starting, acceleration, deceleration, stopping, and steering, and significantly reducing vibration caused by uneven roads. A combination of factors, including wear and tear from prolonged use, poor road conditions, and abnormal tire pressure, can cause a tire blowout while driving. A blowout can easily lead to lateral deviation and loss of control.

[0003] Therefore, installing a tire blowout protection device on a tire is one of the important means to reduce the incidence of serious traffic accidents such as rollover when a vehicle blows out, so a centrifugal structure for a tire blowout protection device is specially designed. Utility Model Content

[0006] Furthermore, a slide groove for placing a reset spring is provided between the two top plates, wherein the arc-shaped connecting plate at the front end is used to provide supporting force for the reset spring, and the arc-shaped connecting plate at the rear end is used to enhance the connection strength of the two supporting vertical plates.

[0007] Furthermore, the swing block assembly and the swing connecting rod assembly both adopt an integrally formed structural design.

[0008] The beneficial effect of the utility model is that the utility model can be combined with the leveling ring assembly to assemble into a ring-shaped tire protection device, thereby providing a good protection effect for the entire vehicle when a tire blows out.

[0009] The top plate on the swing block assembly of the utility model adopts the same curvature as the inner wall of the tire, so that the top plate fits the tire better after being swung open, thereby improving its protective effect; a slide groove is provided to place a return spring, so that the return spring can better hold the swing block assembly; and an arc-shaped connecting plate is provided to increase the structural strength and provide support force for the return spring.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and beneficial effects of the present invention more clear, the technical solution of the present invention is further described below in conjunction with embodiments.

[0020] like Figures 1 to 6 As shown, a centrifugal structure for a tire blowout protection device includes a throwing block assembly and a swing connecting rod assembly.

[0021] The swing block assembly includes a pair of top plates with the same arc as the inner wall of the tire, and a supporting vertical plate is provided on the lower side of each top plate. The front and rear ends of the two supporting vertical plates are respectively connected by arc-shaped connecting plates, and a pin sleeve is provided on the rear side of each supporting vertical plate. A swing link assembly is arranged between the two pin sleeves. The swing link assembly is composed of upper and lower shaft sleeves and two side plates, wherein the upper shaft sleeve and the pin sleeve are coaxially arranged for the pin shaft to be inserted to rotatably connect the swing block assembly and the swing link assembly, and the radius of the lower shaft sleeve is higher than the lower surface of the side plate.

[0022] A sliding groove for placing a reset spring is provided between the two top plates, wherein the arc-shaped connecting plate at the front end is used to provide supporting force for the reset spring, and the arc-shaped connecting plate at the rear end is used to enhance the connection strength of the two supporting vertical plates.

[0023] The centrifugal structure is mounted on the leveling ring assembly, which is equipped with a circular array of locating pin holes. Each locating pin hole is rotatably connected to the lower sleeve of the swing link assembly via a pin. The centrifugal structures form a circular ring aligned with the center of the leveling ring assembly. A return spring is connected end-to-end in a circular ring configuration within a chute. To facilitate installation and disassembly of the entire device and tire removal, the leveling ring assembly consists of two semi-circular rings, one end hinged by a connecting pin and the other end flexibly connected by a hook. Furthermore, due to the uneven outer surface of the wheel rim, heightened ribs are incorporated within the semi-circular rings to ensure better grip on the rim. These ribs and semi-circular rings are integrally molded and cast. The height of the ribs is calculated based on the depth of the groove and the slope of the slope, ensuring the leveling ring assembly is flush within the rim groove and maintaining dynamic balance. During installation, the heightened ribs securely contact the deepest recess of the wheel rim.

[0024] The swing block assembly and the swing connecting rod assembly both adopt an integrated molding structure design, that is, they are cast into an integrated assembly through a mold at one time and then finished by a CNC machine tool for a second time to form an assembly structure.

[0025] This device is installed inside the tire. During installation, the leveling ring assembly is first opened and tightly encircled around the groove of the wheel rim. The hook is then fastened. The swing link assembly is rotatably mounted in the locating pin hole of the leveling ring assembly via the lower bushing. The upper bushing of the swing link assembly is rotatably connected to the pin sleeve of the swing block assembly. The front ends of the rear support plates of adjacent swing block assemblies are pressed against the rear ends of the front support plates, forcing them to fit together. After installation, the return spring is placed in the slide groove, connecting them end to end to form a ring. The return spring now surrounds all the swing block assemblies. During use, the leveling ring is opened and tightly encircled around the groove of the wheel rim. The hook is then fastened.

[0026] Working principle: When the vehicle is driving, since the installation direction of this device is the same as the direction of wheel rotation, a slot for embedding a reset spring is provided in the middle of the top plate of the upper throw block assembly. The slot contains a reset spring that tightens all the throw block assemblies around the leveling ring assembly. When the wheel reaches a certain speed, the centrifugal force generated by the wheel rotation overcomes the elastic force of the reset spring and the block will be automatically thrown away by the centrifugal force. Since the lower part of the throw block assembly is connected to the leveling ring assembly through a swing link assembly, and both ends of the swing link assembly use a movable axle pin structure, after the top plate of the throw block assembly contacts the inner wall of the tire, the curvature of the entire top plate is automatically made to fit closely with the inner wall of the tire.

[0027] When the vehicle speed decreases, the centrifugal force decreases accordingly. When it is less than the elastic force of the reset spring, it will be gradually tightened and reset under the elastic force of the reset spring, waiting for the wheel speed to increase again to carry out the next round of work.

[0028] Except for the technical features described in the specification, the remaining technical features are known to those skilled in the art.
