Description

Rim

The present invention relates to a vehicle component, and more particularly to a rim.

For the driving safety of the vehicle, whether the tire temperature and tire pressure are normal is an important matter that the driver needs to pay attention to at any time.

News about accidents caused by abnormal tire temperature and tire pressure can be seen, especially in highways or fast roads that run at high speeds. If a puncture occurs, serious traffic accidents can easily occur. Therefore, install on the wheels of the vehicle. Tire temperature and tire pressure detector can reduce the accident rate caused by puncture.

For the above reasons, the Ministry of Communications of the People's Republic of China passed the "Car Safety Test Benchmark" amendment in November 2012, and the new type of vehicles for specific types of vehicles to be safely audited after November 1, 2014 must be equipped with a tire pressure detection system ( Tire Pressure Monitoring System (TPMS), otherwise it is not allowed to issue a certificate of conformity. It is also clear that from July 1, 2016, all new vehicles must be installed with TPMS, otherwise they will not be licensed.

Furthermore, the wheel frame used in a single inflatable tire has long faced the dilemma of insufficient nozzle holes, which are respectively described below:

First, all inflatable tires have a pressure limit, but the loss of inflation is not rooted. Taking aircraft tires as an example, personnel are required to work with the tires in a protective cage; casualties have been reported, but the introduction of independent overpressure relief valves has not yet been seen. American tire tire nozzles have been patented from the patent No. 1004986 in 1911. The patents for gas-filled and over-pressure venting composite related nozzles have accumulated more than 60 pieces so far, but they are completely extinct in the market. If this safety valve is reliable enough, today's high-priced TPMS may not be able to become a trend.

Second, although the installation of the tire temperature and tire pressure detector on the wheel can reduce the accident rate, but the arbitrary installation of the tire pressure detector may also cause the wheel to run unbalanced.

Third, the tire's traction and braking ability when wet, slippery sandstone or even snow and ice roads must be drastically reduced, and then advanced anti-locking or tracking control may not cure its roots; Helpless security concerns, so too!

Accordingly, it is an object of the present invention to provide a rim that enhances the driving safety of a vehicle.

Thus, the rim of the present invention comprises a body, a hub and a spoke unit. The body has a hollow ring shape and has an inner annular surface surrounding an axis and forming an inner hole, an outer annular surface opposite to the inner annular surface, and at least two through holes spaced around the axis. The annular surface defines a circumferentially communicating groove around the axis, the through holes are penetrated from the inner annular surface to the outer annular surface, and respectively communicate with the groove, the through holes are distributed in a balanced and symmetrical manner On the body, the hub corresponds to the axis and is located in the inner bore, and the spoke unit is coupled between the inner annular surface of the body and the hub.

The effect of the invention is that the safety of the vehicle can be improved by using the inflation unit corresponding to one of the through holes and the fitting for improving the safety of the tire corresponding to the other through hole.

Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same reference numerals.

Referring to Figures 1 and 2, a first embodiment of a rim of the present invention includes a body 10, a hub 20, a spoke unit 30, an inflation unit 40, and a fitting unit 50.

The body 10 has a hollow ring shape and has an inner annular surface 12 surrounding an axis L and forming an inner hole 11, an outer annular surface 13 opposite to the inner annular surface 12, and a plurality of surrounding the axis L. a through hole 14 disposed at an interval, the outer annular surface 13 defines a circumferentially communicating groove 131 surrounding the axis L, and the through hole 14 extends from the inner annular surface 12 to the outer annular surface 13 and respectively The groove 131 is connected to the groove 131, and when the groove 131 cooperates with a tire (not shown), a gas-filling space is formed in the circumferential direction, and the through holes 14 are also communicated with the gas-filling space. In this embodiment, the number of the through holes 14 is two, and the through holes 14 are spaced apart from each other by 180 degrees around the axis L. The through holes 14 are distributed on the body 10 in a balanced and symmetrical manner.

The hub 20 corresponds to the axis L and is located in the inner bore 11.

The spoke unit 30 is coupled between the inner annular surface 12 of the body 10 and the hub 20.

The inflating unit 40 corresponds to one of the through holes 14 . The inflating unit 40 includes an inflating nozzle 41 mounted in the through hole 14 of the body 10 . The inflating nozzle 41 has an inflating end 411 corresponding to the inner annular surface 12 . And an intake end 412 corresponding to the outer annular surface 13.

The fitting unit 50 is positioned relative to the inflation unit 40 and corresponding to the other through hole 14 of the body 10, and the fitting unit 50 uses the through hole 14 to position relative to the body 10, and the fitting unit 50 and the same The aeration unit 40 forms an equilibrium state. The fitting unit 50 of the embodiment can be an overpressure bleed independent gas valve, a traveling power generation system, an electric energy conversion circuit, an energy storage battery array, a pumping pressure boosting system, a tire pressure and a tire temperature detection. The system, the frame rotation speed and acceleration detection system or a circuit system capable of integrating control, calculation, transmission and reception, a wheel load detection system, or a combination of any two or more thereof, that is, a single A through hole 14 can be connected to any two or more members in a split manner.

Therefore, in the rim of the present invention, by providing the through holes 14 in the body 10 and respectively arranging the inflating unit 40 and the fitting unit 50 corresponding to the through holes 14, not only the rim can be balanced, thereby The safety of driving the vehicle is improved, and the cooperation of the traveling power generation system of the fitting unit 50 and the electric energy conversion circuit can provide the component that needs to be powered, and the energy storage battery array can be used to provide the power supply requirement during parking, and the pumping power supply can be used. The air boosting system can perform automatic inflation and boosting, and the tire pressure and the tire temperature detecting system can automatically detect the tire pressure and the tire temperature, and the wheel frame rotation data can be obtained by using the wheel frame speed and acceleration detecting system, and the The circuit system can be matched to the needs of other components, so that the rim as a whole can have additional functions.

Thereby, the effects that can be produced by the present invention are summarized as follows:

1. The pneumatic unit 40 is installed in one of the through holes 14 of the body 10, and the other through hole 14 is provided for an overpressure and venting independent air valve installation, and the inflation and the tire puncture event can theoretically be completely eradicated. This is not yet available for TPMS. The added benefit is the rapid no-inflating, so that it can be easily implemented on the road, such as a gas station.

2. The PTFE unit is installed in one of the through holes 14 of the body 10, and the existing TPMS is installed in the other through hole 14. The battery capacity and the service life of the TPMS are due to the weight balance provided by the gas unit 40. This can no longer be limited by the addition of balanced lead blocks to the wheel frame; thus the relative annual average cost of TPMS can be significantly reduced.

Third, using the second through hole 14 to install an exhaust pressure reducing valve, the grip area of the tire can be instantaneously inversely proportional to the reduction of the tire pressure, which is beneficial and fully compatible with almost all vehicle control. system. Such an engineering-appropriate emergency electromagnetic valve not only enhances the TPMS's infinite amount of electronic intelligence, let alone such an important new safety protection, can be created cost-effectively through the extra cost of the through hole. !

Fourth, in the future, power generation and inflation systems within the tires will be realized; it seems to be foreseeable that the tire pressure automatic adjustment system that tracks wheel load and tire temperature changes will be born. Looking forward to the vision, it is obvious that the traditional wheel-wheel frame of a single nozzle hole has indeed been difficult to meet the future security and energy-saving evolution needs.

Referring to Figure 4, a second embodiment of the rim of the present invention also includes a body 10', a hub 20', a spoke unit 30', an inflatable unit 40', and a fitting unit 50'. The difference from the first embodiment is that the number of the through holes 14' of the body 10' is three, the through holes 14' are spaced apart from each other by 120 degrees, and the inflating unit 40' corresponds to one of the through holes 14. 'The fitting unit 50' corresponds to the other two through holes 14'. That is to say, the fitting unit 50' can also be a traveling power generation system, an electric energy conversion circuit, an energy storage battery array, an air suction supercharging system, a tire pressure and a tire temperature detecting system, and a frame speed. And the acceleration detection system or a circuit system that can integrate control, calculation, transmission, and reception, or a combination of two or more thereof.

Referring to FIG. 5, a third embodiment of the rim of the present invention also includes a body 10", a hub 20", a spoke unit 30", an inflation unit 40" and a fitting unit 50". The number of "through holes 14" is four, the through holes 14" are spaced 90 degrees around the axis L, the inflating unit 40" corresponds to one of the through holes 14", and the fitting unit 50" corresponds to the other three Through hole 14".
