Description

Technical Field

[0001] The present invention relates to the technical field of tire pressure warning caps, in particular to a tire pressure warning cap for a Presta valve. Background Art

[0002] Bicycles are a common means of transportation, and proper control of tire pressure directly impacts riding safety, comfort, and tire life. Traditional bicycle valves (especially Presta valves) are primarily used to inflate and deflate tires, and structurally consist of only a valve core and a simple sealing assembly. With the increasing professionalization of cycling needs, the need for real-time tire pressure monitoring is becoming increasingly prominent. However, traditional valves lack tire pressure display capabilities and rely on external tire pressure gauges or additional electronic monitoring equipment for measurement. This requires users to carry additional tools or install independent monitoring devices during use, making operation cumbersome and inconvenient.

[0003] In the existing technology, most existing tire pressure warning devices are only compatible with a single type. The one-piece product cannot be screwed into the internal threaded hole of the split type, and the structure of the split replacement valve core is not compatible with the one-piece external threaded valve core, forcing users to purchase special parts for the vehicle valve type, which not only increases costs, but also makes it easy for leakage and loosening due to modification and adaptation, or forced installation may damage the threads, reducing convenience and reliability.

[0004] Therefore, we propose a tire pressure warning cap for a Presta valve. Summary of the Invention

[0005] The purpose of the present invention is to solve the shortcomings existing in the prior art. Most of the existing tire pressure warning devices are only compatible with a single type. The one-piece product cannot be screwed into the internal threaded hole of the split type, and the structure of the split replacement valve core is not compatible with the one-piece external threaded valve core, forcing users to purchase special parts for the vehicle valve type, which not only increases the cost, but also makes it easy to leak and loosen due to modification and adaptation, or force installation to damage the threads, which weakens the convenience and reliability of use.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A tire pressure warning cap for a Presta valve, comprising:

[0008] Aluminum alloy joint, with internal thread section and external thread section, with air passage running through the interior;

[0009] An elastic pressing assembly, consisting of a spring and an annular gasket, wherein the spring is sleeved on the outside of the gas passage, with one end abutting the annular gasket and the other end abutting the valve stem (integrated) or valve seat (split) of the Presta valve during assembly. The spring force pushes open the valve stem / valve seat, allowing gas to enter the gas passage;

[0010] A tire pressure sensor is embedded in the aluminum alloy connector and communicates with the gas passage for detecting gas pressure.

[0011] A lamp bead is electrically connected with the tire pressure sensor and is arranged in the transparent shell to display corresponding color according to the pressure threshold.

[0012] The transparent shell is provided with internal threads at the bottom and is screwed with the external thread segment of the aluminum alloy connector to cover the lamp bead and form a visual observation window.

[0013] A battery is arranged at one end of the transparent shell away from the aluminum alloy connector to supply power to the tire pressure sensor and the lamp bead.

[0014] A sealing gasket is clamped between the screwed surface of the aluminum alloy connector and the transparent shell to seal the gap therebetween.

[0015] As a preferred scheme of the present application, an annular groove is formed on the outside of the external thread segment of the aluminum alloy connector when the split type French valve nozzle is adapted, and a gas seal ring is embedded in the annular groove to seal the gap between the aluminum alloy connector and the mounting hole of the split type French valve nozzle.

[0016] As a preferred scheme of the present application, the inner diameter of the annular gasket of the elastic pressing assembly is adapted to the outer diameter of the valve rod of the French valve nozzle, and the side of the gasket facing the valve rod is provided with anti-skid lines.

[0017] As a preferred scheme of the present application, the inner wall of the transparent shell is provided with a light condensing facet for converging the light of the lamp bead and enhancing the external visibility.

[0018] As a preferred scheme of the present application, the battery is provided with a battery compartment cover, and a waterproof rubber ring is embedded at the connection between the battery compartment cover and the transparent shell.

[0019] As a preferred scheme of the present application, the pitch of the internal thread segment of the aluminum alloy connector is adapted to the pitch of the external thread of the integrated French valve core, and the pitch of the external thread segment is adapted to the pitch of the internal thread of the mounting hole of the split type French valve nozzle.

[0020] Compared with the prior art, the present application has the following beneficial effects:

[0021] In the present application, the elastic pressing assembly adopts an annular gasket combined with anti-skid lines to increase the contact area with the valve rod (integrated) or valve seat (split type), and the anti-skid lines prevent relative displacement caused by vehicle bumping to ensure that the spring continuously and stably presses open the valve rod / valve seat, thereby solving the problems of easy loosening of the existing pressing mechanism and interruption of monitoring and ensuring the continuity of tire pressure detection.

[0022] The inner threaded section and the outer threaded section are arranged through the aluminum alloy joint, and are matched with the outer thread of the integrated French valve core and the inner thread of the mounting hole of the split French valve nozzle respectively, so that the two types of French valve nozzles can be compatible without replacing special parts, the problem that the existing warning device can only adapt to a single type of valve nozzle and the user needs to repeatedly purchase is solved, the use cost is reduced, and the installation complexity and the air leakage risk caused by the adapter fittings are avoided.

[0035] Example

[0036] like Figures 1-7 As shown, the present invention provides a technical solution: a tire pressure warning cap for a Presta valve, comprising: an aluminum alloy joint 10: having an internal thread section and an external thread section, with an air passage running through the interior;

[0037] The elastic pressing assembly 20 is composed of a spring 201 and an annular gasket 202. The spring 201 is sleeved on the outside of the gas passage, with one end abutting the annular gasket 202 and the other end abutting the valve stem of the Presta valve (integrated valve stem or split valve seat) during assembly. The elastic force of the spring 201 pushes the valve stem / valve seat open, allowing gas to enter the gas passage.

[0038] Tire pressure sensor 30: embedded in the aluminum alloy joint 10, connected to the air passage, used to detect gas pressure;

[0039] Lamp bead 40: electrically connected to the tire pressure sensor 30, disposed in the transparent housing 50, and displays a corresponding color according to the pressure threshold;

[0040] Transparent shell 50: The bottom is provided with internal threads, which are screwed to the external thread section of the aluminum alloy joint 10, and the lamp beads 40 are covered to form a visual observation window;

[0041] Battery 60: located at the end of the transparent shell 50 away from the aluminum alloy joint 10, and provides power to the tire pressure sensor 30 and the light bead 40;

[0042] Sealing gasket 70: clamped between the aluminum alloy joint 10 and the transparent shell 50, sealing the gap between the two;

[0043] When the device is screwed through the internal threaded section of the aluminum alloy joint 10 into a one-piece French valve core or the external threaded section into a split valve nozzle mounting hole, the spring 201 of the elastic pressing assembly 20 is compressed to generate a spring force, continuously pressing open the valve stem / seat of the valve nozzle through the annular gasket 202, allowing the tire gas to enter the tire pressure sensor 30 through the gas passage of the aluminum alloy joint 10; the sensor 30 converts the pressure signal into an electrical signal, which is transmitted to the lamp bead 40 through the circuit, driving the lamp bead 40 to display the corresponding color according to the preset threshold value, such as red for low pressure, green for normal pressure, and blue for high pressure. The user can directly observe the tire pressure state through the transparent shell 50; the sealing gasket 70 is compressed when the transparent shell 50 is screwed, filling the gap between the aluminum alloy joint 10 and the transparent shell 50, preventing external water vapor from entering and affecting the circuit operation.

[0044] When the split French valve nozzle is adapted, an annular groove is provided on the outside of the external threaded section of the aluminum alloy joint 10, and a gas seal ring 80 is embedded in the annular groove to seal the gap between the aluminum alloy joint 10 and the split valve nozzle mounting hole;

[0045] When the split valve nozzle is adapted, the original valve core is first unscrewed, the external threaded section of the aluminum alloy joint 10 is screwed into the valve nozzle mounting hole, and the gas seal ring 80 in the annular groove is deformed by the threaded extrusion, tightly fitting the inner wall of the mounting hole to form the first sealing barrier; the sealing gasket 70 seals the connection between the transparent shell 50 and the aluminum alloy joint 10, and the double sealing structure effectively prevents the tire gas from leaking from the threaded gap, ensuring that the pressure value obtained by the tire pressure sensor 30 truly reflects the tire pressure.

[0046] The inner diameter of the annular gasket 202 of the elastic pressing assembly 20 is adapted to the outer diameter of the valve stem of the French valve nozzle, and the side of the gasket facing the valve stem is provided with anti-slip patterns;

[0047] The inner diameter of the annular gasket 202 is precisely matched with the outer diameter of the valve stem, ensuring that the spring force of the spring 201 is transmitted along the axis of the valve stem, avoiding lateral deviation that may cause incomplete opening of the valve stem; the anti-slip patterns are in close contact with the surface of the valve stem / seat under the action of the spring force of the spring 201, increasing the friction force, preventing relative sliding between the elastic pressing assembly 20 and the valve stem / seat during vehicle driving due to vibration, maintaining a stable gas conduction gap, and ensuring that the tire pressure sensor 30 continuously receives the tire gas pressure signal.

[0048] The inner wall of the transparent shell 50 is provided with a light condensing facet for converging the light of the lamp bead 40, enhancing the external visibility;

[0049] When the light emitted by the lamp bead 40 is incident on the light-collecting facet of the inner wall of the transparent shell 50, the special geometric structure of the facet, such as a triangular prism or a circular arc surface, causes the light to be refracted and totally reflected, thereby converging the originally scattered light into a directional light beam and reducing the loss of light energy. In particular, in a backlight or dark environment, the light after being collected is more easily recognized by the user at a long distance, and the color signal displayed by the lamp bead 40, such as green or red, is more clear and eye-catching, thereby improving the accuracy of the judgment of the tire pressure state.

[0050] A battery 60 compartment cover is arranged outside the battery 60, and a waterproof rubber ring is embedded at the connection between the battery 60 compartment cover and the transparent shell 50.

[0051] When the battery 60 compartment cover is screwed or buckled to the transparent shell 50, the waterproof rubber ring is elastically deformed under the extrusion, fills the small gap between the compartment cover and the transparent shell 50, and forms a waterproof barrier. In the scenes such as car washing and driving in the rain, external water cannot penetrate into the inside of the battery 60 compartment, thereby avoiding the short circuit or corrosion of the positive and negative electrodes of the battery 60, ensuring that the battery 60 continuously and stably supplies power to the tire pressure sensor 30 and the lamp bead 40, and prolonging the service life of the device.

[0052] The internal thread pitch of the aluminum alloy connector 10 is adapted to the external thread pitch of the integrated French valve core, and the external thread pitch is adapted to the internal thread pitch of the mounting hole of the split French valve nozzle.

[0053] The internal thread pitch of the aluminum alloy connector 10 is adapted to the external thread pitch of the integrated valve core, such as M8x1.0, to ensure that the thread profile completely matches during screwing, to form sufficient pre-tightening force and prevent loosening during use. The external thread pitch is adapted to the internal thread pitch of the mounting hole of the split valve nozzle, such as M6x0.75, to ensure the sealing and connection strength during replacement of the original valve core. Through the double-pitch design, the same aluminum alloy connector 10 can realize standardized threaded connection with two types of valve nozzles, without the need for additional adapters, thereby simplifying the installation process and improving the adaptability and reliability.

[0054] Work flow

[0055] Installation and adaptation stage

[0056] Adaptation of integrated French valve nozzle: the internal thread of the aluminum alloy connector 10 is screwed onto the external thread of the integrated valve core. During the screwing process, the spring 201 of the elastic top pressing assembly 20 is gradually compressed, and the annular gasket 202 is pressed towards the valve stem of the valve nozzle.

[0057] Adaptation of split French valve nozzle: first, the original valve core of the split valve nozzle is disassembled, and the external thread of the aluminum alloy connector 10 is screwed into the internal thread of the mounting hole. The pitch of the external thread and the pitch of the internal thread of the mounting hole are adapted, and when the aluminum alloy connector 10 is tightened, the sealing ring 80 in the annular groove of the external thread is deformed under the extrusion.

[0058] Transparent shell assembly stage: the inner thread of the bottom of the transparent shell 50 is screwed with the outer thread section of the aluminum alloy joint 10, and the sealing gasket 70 clamped between the two is compressed during the screwing process, sealing the gap between the connection, as claimed in claim 1, while the transparent shell 50 covers the lamp bead 40 to form a visual window.

[0059] Gas conduction stage: after assembly, the spring 201 of the elastic pressing assembly 20 continuously presses the valve rod integrated or the valve seat separated of the gas nozzle, and the annular gasket 202 ensures stable pressing direction and no vibration displacement due to its inner diameter matching the valve rod and anti-slip pattern, so that the gas in the tire enters the device through the gas passage of the aluminum alloy joint 10.

[0060] Tire pressure detection and display stage: the gas entering the gas passage contacts the tire pressure sensor 30, the sensor 30 detects the gas pressure and transmits the signal to the lamp bead 40; the battery 60 supplies power to the sensor 30 and the lamp bead 40, and the waterproof rubber ring at the connection between the battery compartment cover and the transparent shell 50 prevents the battery from being damp; the lamp bead 40 displays the corresponding color according to the pressure threshold, and the light converging facet on the inner wall of the transparent shell 50 converges light to enhance visibility in different environments, and the user can directly identify the tire pressure state through the transparent shell.

[0061] Although embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
