Description

Technical Field

[0001] The utility model relates to the technical field of bicycle tire pressure monitoring, in particular to a bicycle tire pressure LED electronic monitor. Background Art

[0002] Tire pressure, strictly speaking, refers to the pressure of the air inside the tire. Now many tires are not filled with air. For these tires, the tire pressure requirements are relatively strict. And tires filled with air are related to the change of seasons. In addition, tire pressure is closely related to the performance of the car, such as comfort and carrying capacity, and it will also affect the life of the tire. The air pressure is the life of the tire. Too high or too low will shorten the service life of the tire. Too low air pressure will increase the deformation of the tire body, and cracks will easily appear on the sidewalls. At the same time, flexion movement will occur, resulting in excessive heat, rubber aging, cord fatigue, cord breakage, and increase the tire contact area, accelerating the wear of the shoulder. Too high air pressure will cause excessive stretching and deformation of the tire cord, reduce the elasticity of the tire body, and increase the load on the car during driving. In case of impact, internal cracks and explosions will occur. At the same time, too high air pressure will accelerate the wear of the crown and reduce the rolling resistance.

[0003] The existing bicycle tire pressure detection method is usually to squeeze the bicycle tire by hand, and judge whether the bicycle tire pressure is normal by the depth of squeezing the tire. However, this method has a large error when detecting tire pressure. It is affected by factors such as each person's strength and environment, and it is usually difficult to perform accurate detection. Therefore, we propose a bicycle tire pressure LED electronic monitor. Utility Model Content

However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0027] It should be noted that when an element is referred to as being "fixed on" another element, it may be directly on the other element or there may also be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used in this article includes any and all combinations of one or more related listed items. Example

[0029] like Figure 1-6As shown, the utility model provides a technical solution: a bicycle tire pressure LED electronic monitor, comprising a shell body 1, an installation cavity 2 is opened inside the shell body 1 and near the right side, a rubber diaphragm 3 is provided inside the installation cavity 2 and near the top, a second shell 4 is threadedly connected to the bottom inside the installation cavity 2, a sleeve 5 is provided inside the second shell 4 and near the top, a limit contact ring 6 is provided on the outside of the sleeve 5, a conductive block 7 is also provided inside the sleeve 5, and limit contact blocks 8 are also provided on both sides of the conductive block 7, a compression spring 9 is provided at the bottom of the conductive block 7, and a lamp bead flashing structure 10 is provided at the bottom and near the bottom of the second shell 4, and the lamp bead flashing structure 10 can flash and display, when the tire pressure of the bicycle is insufficient, the conductive block 7 will contact the limit contact ring 6 under the action of the compression spring 9, so that the lamp bead flashing structure 10 can form a circuit closed loop with the conductive block 7, the limit contact ring 6, and the second shell 4, so that the lamp bead flashing structure 10 can flash and alarm after power is turned on, thereby playing a warning role and realizing automatic monitoring and alarm functions. Example

[0030] like Figure 1-6 As shown, the utility model provides a technical solution: the rubber diaphragm 3 can be fixed to the surrounding walls of the mounting cavity 2 through the mounting ring 11, and the fixing method is welding connection. The top of the second shell 4 is open and connected with the inside of the mounting cavity 2. The conductive block 7 and the limit contact block 8 are integrated and made of the same material. The mounting ring 11 is fixed to the surrounding walls of the mounting cavity 2 by welding, and the rubber diaphragm 3 is fixedly mounted on the mounting ring 11. Therefore, when the rubber diaphragm 3 is subjected to force to change its own shape, its surroundings will not be separated from the fixed point, so that the rubber diaphragm 3 itself can change its shape without changing its position, and the shell 5 can be squeezed to change the position of the shell 5.

[0031] A Presta valve core 12 is provided inside the shell body 1 and near the left side, and a gas communication chamber 13 is provided inside the shell body 1 and above the mounting chamber 2. The gas communication chamber 13 and the mounting chamber 2 are connected via a connecting hole 14. The gas inside the bicycle tire enters the shell body 1 through the Presta valve core 12, and enters above the rubber diaphragm 3 through the gas communication chamber 13 and the connecting hole 14, and squeezes the rubber diaphragm 3, so that the shape of the rubber diaphragm 3 changes.

[0032] The material of the shell 5 is insulating plastic material, and the shell 5 is in conflict with the rubber diaphragm 3. Since the gas enters the top of the rubber diaphragm 3 from the gas communication cavity 13 and the connection hole 14, the gas flows from top to bottom, thereby squeezing the top of the rubber diaphragm 3, so that the bottom of the rubber diaphragm 3 bulges downward and squeezes the shell 5, so that the position of the shell 5 changes. Since the material of the shell 5 is insulating plastic, the shell 5 will not conduct electricity and play an insulating role.

[0033] The lamp bead flashing structure 10 includes a structural shell 101, and a plurality of batteries 102 are arranged inside and near the top of the structural shell 101. A cover plate 103 is arranged at the bottom of the plurality of batteries 102, and an LED lamp 104 is arranged at the bottom of the cover plate 103. A transparent cover 105 is arranged under the LED lamp 104. The battery 102 can provide power for the LED lamp 104 beads. The cover plate 103 is used to support and seal the bottom of the battery 102 and provide an installation position for the battery 102. The transparent cover 105 is supported by an acrylic plate. When the user observes the LED lamp 104, the user can clearly observe the flashing of the LED lamp 104 through the acrylic plate.

[0034] The transparent cover 105 is fixedly connected to the structural shell 101, and wires are provided at the connection points of the battery 102 and the LED lamp 104. The two wires are respectively connected to the battery 102, the conductive block 7, the LED lamp 104 and the structural shell 101. The transparent cover 105 and the structural shell 101 are fixed. Since the structural shell 101 is made of conductive material and the transparent cover 105 is made of insulating material, direct contact with the structural shell 101 can be avoided. At the same time, the wire part of the battery 102 is connected to the conductive block 7, so that the conductive block 7 itself will be attached with electrical properties.

[0035] The lamp bead flashing structure 10 is connected through the internal thread of the structural shell 101 and the second shell 4, the limit contact ring 6 is fixedly connected to the second shell 4, the structural shell 101, the conductive block 7, the limit contact ring 6 and the second shell 4 are all made of conductive materials, and when the tire pressure of the bicycle tire is low, the rubber mold piece returns to the initial plane state, and the conductive block 7 and the limit contact ring 6 are contacted under the action of the compression spring 9, and the limit contact ring 6 is fixedly connected to the second shell 4, and the second shell 4 is connected to the structure of the lamp bead flashing structure 10. The structural housing 101 is connected, and a wire is provided between the structural housing 101 and the LED lamp 104. Therefore, when the tire pressure drops, the conductive block 7 contacts the limit contact ring 6, and the battery 102 transmits the current to the conductive block 7 through the wire, and reaches the structural housing 101 through the conductive block 7, the limit contact ring 6, and the second housing 4, and finally reaches the LED lamp 104 through the wire connected by the structural housing 101 and the LED lamp 104, completing the circuit closure, causing the LED lamp 104 to flash, thereby realizing the reminder function.

[0036] An air guide hole plugging bolt 15 is threadedly connected to the inside of the gas connecting chamber 13 near the right side. The air guide hole plugging bolt 15 can seal the gas connecting chamber 13 and can also be opened for deflation. By opening the air guide hole plugging bolt 15, the gas connecting chamber 13 can be connected to the outside world, so that the gas inside the bicycle tire can reach the outside world through the gas connecting chamber 13, completing the deflation operation inside the tire.

[0037] The working process of the utility model is as follows: Step 1, the gas inside the bicycle tire will enter the inside of the outer shell body 1 through the French valve core 12, and enter the top of the rubber diaphragm 3 through the gas connecting cavity 13 and the connecting hole 14, and squeeze the rubber diaphragm 3, so that the shape of the rubber diaphragm 3 is changed. Since the gas enters the top of the rubber diaphragm 3 from the gas connecting cavity 13 and the connecting hole 14, the gas flow direction is from top to bottom, and then the top of the rubber diaphragm 3 is squeezed, so that the bottom of the rubber diaphragm 3 bulges downward, and squeezes the shell 5, so that the position of the shell 5 is changed. Since the bottom of the shell 5 is connected to the conductive block 7 and the compression spring 9, when the internal air pressure of the tire is sufficient, under the action of the tire pressure, it will maintain balance with the compression spring 9, so that the limiting contact block 8 and the limiting contact ring 6 of the conductive block 7 are always separated, so that no current loop is generated, and the LED light 104 will not light up. At this time, the surface tire pressure is sufficient.

[0038] Step 2, when the tire pressure inside the bicycle tire is insufficient, under the action of the tire pressure, its pressure is not enough to maintain balance with the compression spring 9. As the rubber mold returns to its initial planar state, the conductive block 7 will contact the limit contact ring 6 under the action of the compression spring 9, and the limit contact ring 6 is fixedly connected to the second shell 4, and the second shell 4 is connected to the structural shell 101 of the lamp bead flashing structure 10. A wire is provided between the structural shell 101 and the LED lamp 104. Therefore, when the tire pressure drops, the conductive block 7 contacts the limit contact ring 6, and then the battery 102 transmits the current to the conductive block 7 through the wire, and reaches the structural shell 101 through the conductive block 7, the limit contact ring 6, and the second shell 4, and finally reaches the LED lamp 104 through the wire connected by the structural shell 101 and the LED lamp 104, completing the circuit closure, causing the LED lamp 104 to flash, thereby realizing the reminder function.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
