Detailed Description

The following further describes embodiments of the present invention with reference to the accompanying drawings. In which like parts are designated by like reference numerals. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

As shown in fig. 1 to 6, a rim device according to an embodiment of the present invention includes a rim 1 and a tire support plate 2 for supporting a tire when the tire is punctured.

An annular rail 3 is fixedly provided on the outer circumferential surface of the rim 1.

Two or more tire support plates 2 are arranged on the rail 3 at intervals in the circumferential direction.

The tire support plate 2 includes a rotating plate 21 rotatable on the rail 3 and a sliding plate 22 rotatable and slidable on the rail 3, the rotating plate 21 and the sliding plate 22 being pivotably connected.

The slide plate 22 has an initial position and a working position on the rail 3.

When the slide plate 22 is in the initial position, the slide plate 22 and the rotating plate 21 are both laid on the rail 3, and the tire support plate 2 is in the unfolded state on the rail 3.

When the slide plate 22 is in the operating position, both the slide plate 22 and the rotating plate 21 are extended outward of the rail 3, and the tire support plate 2 is in an extended state on the rail 3.

The invention provides a rim device which is a part in a wheel and is used for mounting a tire.

The rim device mainly comprises a rim 1, a tire support plate 2 and a track 3. The track 3 is an annular track which is fixedly mounted on the outer circumferential surface of the rim 1. The rails 3 may be bolted to the rim 1 or may be welded to the rim 1.

The tire supporting plate 2 is arranged on the track 3 and used for supporting the tire when the tire is burst so as to prevent the tire from sinking greatly, avoid the tire from losing the supporting force instantaneously, win the normal control time of the vehicle for a vehicle owner and effectively avoid traffic accidents caused by the burst.

More than two tire support plates 2 are arranged at intervals in the circumferential direction of the track 3, and the number of the tire support plates 2 can be set according to actual needs. Preferably, a plurality of tire support plates 2 are uniformly distributed on the rail 3 to improve the support effect on the flat tire.

The tire support plate 2 is mainly composed of a rotating plate 21 and a sliding plate 22.

An end of the rotating plate 21 remote from the sliding plate 22 is pivotally connected to the rail 3 by a shaft or hinge so that the rotating plate 21 can rotate on the rail 3. The end of the rotating plate 21 far away from the sliding plate 22 is fixed on the track 3 and will not slide on the track 3, so that the rotating plate 21 can only rotate but can not slide.

An end of the sliding plate 22 remote from the rotating plate 21 is slidably connected to the rail 3 by a sliding pin or a sliding shaft, so that the sliding plate 22 can slide on the rail 3. Meanwhile, the sliding plate 22 can rotate by taking a sliding pin or a sliding shaft as an axis, so that the sliding plate 22 can rotate on the track 3.

The rotating plate 21 and the sliding plate 22 are pivotally connected, and may be connected by a rotating shaft or a hinge so that the sliding plate 22 and the rotating plate 21 may rotate relative to each other.

Thus, when the rim 1 rotates, the slide plate 22 can slide toward the rotating plate 21 by the centrifugal force. The sliding plate 22 and the rotating plate 21 can rotate relatively, when the sliding plate 22 slides towards the rotating plate 21, the sliding plate 22 pushes the rotating plate 21 to rotate, and simultaneously the sliding plate 22 also rotates under the action of the rotating plate 21, so that the sliding plate 22 and the rotating plate 21 are both protruded or spread towards the outer side of the rim 1, and the support can be provided for the tire after the tire burst.

Upon installation, the slide plate 22 has an initial position and an operative position. The slide plate 22 can be automatically moved to the working position by the action of centrifugal force and cannot be automatically moved from the working position to the initial position. When it is desired to move from the working position to the initial position, an operator is required to operate the slide plate 22.

When the sliding plate 22 is in the initial position, both the sliding plate 22 and the rotating plate 21 are laid on the rail 3. At this time, the tire support plate 2 is in a spread state on the rail 3, and the mounting of the tire on the rim 1 is not affected.

After the tire is mounted in place, the rim 1 or wheel is rotated in the direction from the rotating plate 21 to the sliding plate 22 in the tire support plate 2, and the sliding plate 22 automatically moves toward the working position under the centrifugal force, and finally the rotating plate 21 and the sliding plate 22 are spread outward. At this time, the tire support plate 2 is in a supported state on the rail 3, and the effect of supporting the tire in the event of tire burst can be achieved.

In general, dynamic balance is needed before the wheel is installed, and a special rotating step is not needed to prop up or prop up the tire supporting plate 2, so that the use is convenient.

All the tire support plates 2 on the track 3 are uniformly arranged, that is, the relative positions of the rotating plate 21 and the sliding plates 22 in each tire support plate 2 are consistent, when the rim 1 rotates towards a certain direction, all the sliding plates 22 can move towards the working position, and when the tire is blown out, all the tire support plates 2 can act, so that the tire support effect during the blowing out is improved.

In summary, the present invention provides a rim device, in which the tire support plate 2 is initially laid on the rim 1 or the rail 3, without affecting the mounting and dismounting of the tire. When rim 1 rotates or the tire rotates, sliding plate 22 slides towards rotating plate 21 under the action of centrifugal force, and drives rotating plate 21 to rotate, and sliding plate 22 self also can rotate simultaneously, makes rotating plate 21 and sliding plate 22 all outwards strut, thereby makes the tire backup pad be in the state of strutting, and it is protruding towards the tire side, can be used to support the tire that blows out.

When the tire bursts and loses pressure, the tire supporting plate 2 in the supporting state can support the tire surface to avoid substantial sinking, the problem that the tire completely loses pressure to cause vehicle out of control is avoided, normal control time of the vehicle is won for a vehicle owner, and traffic accidents caused by tire burst are effectively avoided.

The rim device provided by the invention can be suitable for common pneumatic tires, the cost of the tire support plate is lower than that of the explosion-proof thickened rubber, and the structure and the performance of the common pneumatic tire cannot be influenced by the tire support plate, so that the riding comfort cannot be influenced.

Preferably, since the track 3 is circular, the rotating plate 21 and the sliding plate 22 are arc-shaped plates respectively, so that the rotating plate 21 and the sliding plate 22 in the initial position are both attached to the track 3.

Preferably, the track 3 is arranged on the outer half of the rim 1, so that the tire support plate 2 is also located on the side close to the outside of the rim 1. When the tire blows out, the tire support plate 2 can be supported at the position close to the outside, and when the tire blows out, the outer side of the tire bursts instantly to lose the support, and the vehicle turns outwards to cause out of control.

In general, if a tire bursts, the support force of the punctured tire is lost, and the vehicle inclines towards the burst side and the direction of the vehicle is deviated towards the burst side.

The right front wheel is illustrated below:

if the right front wheel is punctured, the vehicle tilts to the right front, the vehicle body weight presses on the rim hill of the right front wheel, and the vehicle running track deviates to the right front.

With tire support plate 2 setting one side outside on rim 1, when blowing out, tire support plate 2 provides interim support by the outside, can furthest avoid the vehicle skew.

In order to avoid affecting the installation and use of the valve, as shown in fig. 3, a notch 30 is provided on the track 3 near the valve for avoiding the valve.

In one embodiment, a slide plate stopper for stopping the slide plate 22 in the working position is further provided on the rail 3.

When the sliding plate 22 is in the working position, the end of the sliding plate 22 away from the rotating plate 21 is limited by the sliding plate limiting part.

The sliding plate limiting part can be a stopping part, a stopping pin, a stopping protrusion or a stopping groove and the like arranged on the track 3.

The purpose of the slide plate stopper is to prevent the tire support plate 2 from losing its support function because the slide plate 22 cannot be automatically moved back to the initial position after being automatically moved to the working position.

In one embodiment, as shown in fig. 4-6, one end of the rotating plate 21 away from the sliding plate 22 is fixedly provided with a first pivot shaft 23, and the other end thereof is connected with the sliding plate 22 through a second pivot shaft 24, and one end of the sliding plate 22 away from the rotating plate 21 is fixedly provided with a sliding pin 25.

The first pivot shaft 23 is rotatably mounted on the track 3. The slide pin 25 is slidably mounted on the rail 3, and the slide pin 25 can rotate on the rail 3.

The first pivot shaft 23 is a mounting shaft for mounting the end of the rotating plate 21 remote from the slide plate 22 to the rail 3 and causing the rotating plate 23 to rotate together with the shaft. The first pivot shaft 23 is integrally formed on an end of the rotating plate 21.

The second pivot shaft 24 is a mounting shaft for connecting the slide plate 22 and the rotating plate 21 and enabling the slide plate 22 and the rotating plate 21 to rotate relative to each other. Of course, the sliding plate 22 and the rotating plate 21 may be connected by a hinge.

The slide pin 25 is a mounting pin for connecting an end of the slide plate 22 remote from the rotating plate 21 to the rail 3 while allowing the slide plate 22 to slide on the rail 3 and to rotate together with the pin. The slide pin 25 is integrally formed on an end of the slide plate 22.

In this embodiment, the first pivot shaft 23 rotates integrally with the rotating plate 21. The slide pin 25 slides and rotates integrally with the slide plate 22.

When the slide plate 22 is subjected to centrifugal force, the slide pin 25 moves on the rail 3 toward the rotating plate 21, bringing the slide plate 22 to move toward the working position. When the slide plate 22 moves toward the rotating plate 21, the distance between the slide pin 25 and the first pivot shaft 23 decreases, so that the first pivot shaft 23 and the rotating plate 21 rotate together, and the rotating plate 21 is spread outward from the rim 1. The rotating plate 21 rotates and simultaneously drives the second pivot shaft 24 to move towards the outer side of the rim 1, and the second pivot shaft 24 pulls the end of the sliding plate 22 to expand outwards, so that the sliding plate 22 drives the sliding pin 25 to rotate in the track 3.

During the movement of the sliding plate 22 from the initial position to the working position, the rotating plate 21 only rotates by one action, and the sliding plate 22 has both sliding and rotating actions.

In one embodiment, the rotating plate 21 and the sliding plate 22 are mounted in another way, specifically as follows: one end of the rotating plate 21 far away from the sliding plate 22 is mounted on the track through a fixed shaft, the other end thereof is connected with the sliding plate 22 through a third pivot shaft, and one end of the sliding plate 22 far away from the rotating plate 21 is mounted on the track through a sliding shaft. The fixed shaft is fixedly installed on the rail 3, and the rotating plate 21 can rotate around the fixed shaft. The slide shaft is slidably mounted on the rail 3, and the slide plate 22 can rotate about the slide shaft.

In this embodiment, the fixed shaft does not rotate with the rotating plate 21, and the end of the rotating plate 21 is fitted over the fixed shaft. The sliding shaft is only slid and not rotated, and the sliding plate 22 is fitted over the sliding shaft.

In one embodiment, as shown in fig. 3 to 6, the rail 3 includes two annular guide rails 31, and the two guide rails 31 are arranged at intervals in the axial direction of the rim 1.

The two ends of the first pivot shaft 23 are pivotally connected to the two guide rails 31, respectively.

The side of the guide rail 31 is provided with a guide rail sliding groove 32, and two ends of the sliding pin 25 are respectively connected with the two guide rail sliding grooves 32 in a sliding manner.

In this embodiment, the track 3 is composed of two guide rails 31 arranged at intervals in the axial direction of the rim 1. The guide rail 31 is also circular and can be mounted on the rim by means of bolts or can be welded to the rim 1.

Both ends of the first pivot shaft 23 are respectively installed in the installation holes of the two guide rails 31, and the first pivot shaft 23 is rotated in the installation holes so that the rotating plate 21 can be rotated together with the first pivot shaft 23.

The two ends of the sliding pin 25 are located in the guide rail sliding grooves 32 on the two sides, and the end part of the sliding pin 25 is in clearance fit with the guide rail sliding grooves 32, so that the sliding pin 25 can slide in the guide rail sliding grooves 32 and can rotate in the guide rail sliding grooves 32, and further the sliding plate 22 can slide and rotate.

In one embodiment, as shown in fig. 6 to 8, a slide pin stopper 33 for stopping the slide pin 25 is provided in the guide rail slide groove 32.

When the slide plate 22 is in the initial position, the slide pin stopper 33 is located between the first pivot shaft 23 and the second pivot shaft 24.

The slide pin stopper 33 includes a stopper recess 331 provided on the bottom surface of the guide rail slide groove 32.

When the slide plate 22 is in the working position, the slide pin 25 is located in the limit recess 331.

The closer the working position of the slide pin 25 is to the first pivot axis 331, the farther the end of the slide plate 22 is from the rim 1 when it is supported by the rotary plate 21, and therefore the closer it is to the tire, the better the support of the punctured tire can be achieved, and the extent of the tire sagging can be reduced.

When the slide plate 22 is in the operating position, the slide pin 25 is restricted by the slide pin restricting portion 33. The slide pin stopper 33 determines the operating position of the slide pin 25.

The position of the slide pin stopper 33 is located between both ends of the rotating plate 21 at the initial position, that is, when the slide plate 22 and/or the rotating plate 21 is at the initial position, the slide pin stopper 33 is located between the first pivot shaft 23 and the second pivot shaft 24.

The sliding pin position limiting portion 33 includes a position limiting recess 331, the position limiting recess 331 is formed on the bottom surface of the guide rail sliding groove 32, and when the sliding plate 22 is at the operating position, the sliding pin 25 is positioned in the position limiting recess 331 and is limited by the position limiting recess 331, so that it cannot move out of the position limiting recess 331 automatically.

In one embodiment, as shown in fig. 7 to 8, the slide pin stopper 33 further includes a stopper protrusion 332 provided on the top surface of the guide rail runner 32, the stopper protrusion 332 convexly extending toward the stopper recess 331.

When the sliding plate 22 is in the working position, the sliding pin 25 is simultaneously limited by the limiting convex part 332 and the limiting groove 331, and the limiting effect on the sliding pin 25 is improved.

In one embodiment, as shown in fig. 9, the width of the rotating plate 21 is greater than the width of the track 3, and the width of the sliding plate 22 is greater than the width of the track 3, so as to improve the supporting effect of a flat tire.

In one embodiment, as shown in fig. 10, two or more rails 3 are arranged on the rim 1 at intervals in the axial direction. A plurality of tire support plates 2 are mounted on each rail 3 at intervals.

Wherein the tire support plates 2 on any two adjacent rails 3 are arranged side by side in the axial direction along the rim 1.

The second scheme is as follows: the tire support plates 2 on the adjacent two rails 3 are arranged alternately in the circumferential direction along the rim 1. By staggered arrangement, it is meant that one tire support plate 2 on one track 3 of two adjacent tracks 3 is located between two adjacent tire support plates 2 on the other track 3 in the circumferential direction along the rim 1. So set up for tire backup pad 2 on two adjacent tracks 3 supports different positions in the circumferencial direction, can support the tire of blowing out in different positions, has improved the support effect to the tire of blowing out.

Preferably, when the tire support plates 2 on two adjacent rails 3 are arranged in a staggered manner, one tire support plate 2 on one rail 3 is positioned in the middle of two adjacent tire support plates 2 on the other rail 3.

In one embodiment, as shown in fig. 11, a rotating plate bending plate 211 is disposed on one end of the rotating plate 21 close to the sliding plate 22, and a sliding plate bending plate 221 is disposed on one end of the sliding plate 22 close to the rotating plate 21. The rotating plate bending plate 211 and the sliding plate bending plate 221 can be pivotally connected.
