Description

Technical Field

[0001] The utility model relates to the technical field of intelligent tires, in particular to a multifunctional extended external valve. Background Art

[0002] Existing intelligent tires are embedded or built-in sensor devices. The power supply inside the sensor and the signal transmission collected by the sensor become the key to the normal operation of intelligent tires. For traditional TPMS, due to its low sampling frequency and low power consumption, its built-in button battery and antenna can meet the requirements. However, with the continuous expansion of the functions of intelligent tires, the acquisition and transmission frequencies increase, and the power consumption increases significantly. The traditional built-in power supply battery can no longer meet the long-life requirements of intelligent tires, and the tires must be frequently loaded and unloaded, resulting in artificial damage to intelligent tires. The power supply of intelligent tires mainly includes solutions such as placing large-capacity batteries and self-generating electricity inside the tires. However, with the increase in battery capacity, its volume and weight also increase, and the dynamic balance after the tire rotates cannot be guaranteed. Moreover, this method is only applicable to the test stage. If it is put into mass production, its power supply still cannot meet the actual requirements. Secondly, for internal tire power supply, friction power generation is mainly used, and the generated power is small. For intelligent tires with built-in strain and acceleration sensors, the generated power cannot meet the requirements. Therefore, a multifunctional extended external valve is needed to meet the requirements. Summary of the Utility Model

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0020] Referring to Figures 1-4 , a multifunctional extended external valve stem includes a first valve stem 1 and a second valve stem 2. The first valve stem 1 is connected to the tire. A first sleeve 3 is movably connected to the first valve stem 1. The second valve stem 2 is in a Y shape. The inner thread of the top branch is connected to a valve core 4, and the outer thread of the branch is connected to a valve cap 5. An energized wire airtight layer 6 is arranged in the other branch end, and a locking plug 7 is threadedly connected at the opening. A second sleeve 8 is arranged at the bottom end of the second valve stem 2. An ear plate 9 is connected to the outer wall of the second sleeve 8. A cam 10 is rotatably connected to the ear plate 9. A handle 11 is arranged on the cam 10. The cam 10 penetrates through the side wall of the second sleeve 8 and contacts the outer wall of the first sleeve 3.

[0021] During installation, the first sleeve 3 is connected to the first valve stem 1 of the original vehicle tire, and the second sleeve 8 is sleeved on the first sleeve 3. By rotating the cam 10 with the handle 11, while the cam 10 generates a thrust on the first sleeve 3 into the second sleeve 8, the connection between the first sleeve 3 and the second sleeve 8 is ensured. On the contrary, the separation between the first sleeve 3 and the second sleeve 8 is realized. By adding the second valve stem 2 to the first valve stem 1 of the original vehicle tire, the operations of conducting electricity and inflating and deflating can be realized simultaneously without damaging the existing integral wheel hub. It can not only ensure the energy required for the sensor to collect signals and transmit data, but also realize the inflation and deflation of the tire to ensure the normal operation of the entire intelligent tire. The valve core 4 mainly controls the entry and exit of gas. While the valve cap 5 prevents the blockage of the valve core 4, it further improves the air retention property of the valve core 4. The energized wire airtight layer 6 is mainly used for the air retention property of the gas passing through the energized wire, and the locking plug 7 prevents the energized wire airtight layer 6 from being pushed out by the air pressure.

[0022] Specifically, in this embodiment, the inner threads of the first valve stem 1 and the second valve stem 2 are the same, the valve core 4 can be movably connected inside the first valve stem 1, the outer threads of the first valve stem 1 and the second valve stem 2 are the same, and the valve cap 5 can be movably connected to the first valve stem 1 to realize the supporting use with the first valve stem 1 on the original vehicle tire.

[0023] Specifically, in this embodiment, a threaded hole 12 is opened inside the first sleeve 3, and the first sleeve 3 is threadedly connected to the first valve stem 1, realizing the detachability between the first sleeve 3 and the first valve stem 1 and retaining the structure of the first valve stem 1 of the original vehicle tire.

[0024] Specifically, in this embodiment, a notch 13 is provided on the outer wall of the second sleeve 8, and the length of the notch 13 is greater than the maximum diameter of the rotation of the cam 10, providing sufficient and effective space for the rotation of the cam 10.

[0025] Specifically, in this embodiment, a groove 14 is provided on the outer wall of the first sleeve 3. The groove 14 is arranged in a ring shape, and the cam 10 can be fitted into the groove 14, facilitating the rotation of the cam 10 and its engagement with the groove 14 to realize the connection between the second sleeve 8 and the first sleeve 3.

[0026] Specifically, in this embodiment, a rubber pad 15 is embedded in the outer wall of the cam 10. The rubber pad 15 can contact the groove 14, increasing the friction between the cam 10 and the first sleeve 3 and preventing the loosening between the first sleeve 3 and the second sleeve 8 caused by the rotation of the cam 10.

[0027] Specifically, in this embodiment, a gasket 16 is provided on the end surface of the second sleeve 8 in contact with the first sleeve 3 to improve the airtight effect of the connection between the first sleeve 3 and the second sleeve 8.

[0028] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
