Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This PCT application claims the benefit of U.S. Provisional Patent Application Serial No. 17 / 873,558, filed on July 26, 2022, which is incorporated herein by reference in its entirety. Technical Field

[0003] The present invention generally relates to a brake warning system and, more particularly, to a brake warning system that can indicate the condition of brake pads or warn that brake pads may need to be replaced. Background Art

[0004] There are many car owners who don't consider brake maintenance a priority until a problem arises. To keep your brake maintenance system functioning properly, certain parts must be replaced regularly. Of these parts, perhaps the most in need of replacement are your brake pads.

[0005] Automakers install two types of brakes on passenger cars: disc brakes and drum brakes. Both use friction to slow a vehicle, but there are differences. Disc brakes use "pads," which are made of specially designed pieces of friction material, such as organic, metallic, or ceramic, that press against a rotor or "brake disc" when the driver applies the brakes; the resulting friction slows the vehicle. Drum brakes also use friction material, much like disc brake pads, but they are attached to half-moon-shaped "brake shoes," which press against the inside of a brake drum when the driver applies the brakes; their friction against the drum slows the vehicle.

[0006] Each time a driver applies the vehicle's brakes, a small amount of friction material wears away from the brake pads. Over time, the friction material becomes thinner. If the brake pads are not replaced, the friction material will wear away completely, exposing the steel pieces that hold the material. When these steel pieces come into contact with the brake rotor or drum, it will result in excessive stopping distances and damage to the brake rotor and drum.

[0007] There are signs that indicate when it is time to replace brake pads, such as screeching or squealing noises, brake pads that are less than a quarter inch, deep metal grinding and rumbling, and brake fade.

[0008] A sharp, rasping or rattling noise is caused by a small metal attachment on the brake pad backing plate that is designed for this purpose; if you hear this noise frequently when braking, it's time to take your vehicle to a brake specialist for inspection and replacement.

[0009] On disc brakes, the brake pads can also be visually inspected to determine if they are due for replacement. However, this inspection may require the removal of the wheel. If the friction material on the brake pads is less than 1 / 4 inch (about 7 mm) thick, it is time to take the vehicle to a brake specialist for inspection and replacement.

[0010] If you hear a low noise that sounds like metallic grinding or a rumbling roar, this could be a sign that not only the brake pads are worn, but also that the brake pads are making contact with the brake rotors; since this metal-to-metal contact can quickly lead to further damage to the brake system, it's time to take the vehicle to a brake specialist for inspection and replacement.

[0011] Brake fade is a direct result of intentionally applying the brakes over long distances without bringing the vehicle to a complete stop. By forcing the brake pads to be in uninterrupted contact with the rotors for long periods of time, both components heat up. In this process, over time, the ability to create the required friction against each other decreases. As a result, the driver will find that the vehicle will not come to a complete stop.

[0012] There are other signs that you can tell when it's time to replace your brake pads. For example, a vehicle's brake pads won't always wear at exactly the same rate, and sometimes the pads on one side will thin faster than the pads on the other side. If this happens, the vehicle may pull slightly to the left or right once the driver applies the brakes.

[0013] However, none of the above methods and signs can provide a color indicator to indicate whether the condition of the brake pad is a "good" condition or a "bad" condition. In addition, none of the above methods and signs can directly generate an alert message for the user to see on the user device.

[0014] Therefore, there is a need to solve at least one of the above problems. Summary of the invention

[0071] In this embodiment of the present invention, the sensing device 104 may be, but is not limited to, a sensor. For example, a current sensor is a device that detects the current in a wire and generates a signal proportional to the current. The generated signal may be an analog voltage or current or a digital output. The generated signal may then be used to display the measured current in an ammeter, or may be stored in a data acquisition system for further analysis, or may be used for control purposes.

In this manner, the sensing device 104 detects the current level passing through the brake pad 116 for wear condition monitoring, the controller device 150 receives the current level detected by the sensing device 104, and determines the current amount, and the controller device enables the light emitting device 104 based on the determined current amount. Of course, according to the principles of the disclosed embodiments, other types of sensors may be used to monitor the brake pad 116, including but not limited to thermal sensors, magnetic sensors, and distance sensors.

[0072] In this embodiment of the present invention, the light emitting device 106 may be, but is not limited to, a light emitting diode (LED). An LED is a semiconductor light source that emits light when an electric current passes through it. Electrons in a semiconductor recombine with electron holes to release energy in the form of photons. The color of the light (corresponding to the energy of the photon) is determined by the energy required for the electron to cross the semiconductor band gap. White light is obtained by using a layer of light emitting phosphors on a plurality of semiconductors or semiconductor devices. LEDs are commonly used in various applications such as aviation lighting, fairy lights, car headlights, advertising, general lighting, traffic signals, camera flashes, lighting wallpaper, gardening grow lights, and medical equipment. In this way, LEDs have many advantages over incandescent light sources, including lower power consumption, longer life, improved physical robustness, smaller size, and faster switching speeds. In one embodiment of the present invention, specifically, the light emitting device 106 is an LED capable of emitting green light, yellow light, and red light. In this embodiment, the light emitting device includes a plurality of LEDs, wherein each corresponding LED in the plurality of LEDs is capable of generating each corresponding color code in a plurality of color codes, which are used to indicate the state of the brake pad 116 according to the monitored wear condition.

[0073] In this embodiment of the present invention, the signal transmitting device 108 can be, but is not limited to, a transmitter. In electronics and telecommunications, a transmitter or radio transmitter is an electronic device that generates radio waves with an antenna. The transmitter itself generates a radio frequency alternating current that is applied to the antenna. When excited by this alternating current, the antenna radiates radio waves. Transmitters are essential components of electronic devices that communicate via radio, such as radio and television broadcast stations, cell phones, walkie-talkies, wireless computer networks, Bluetooth devices, garage door openers, two-way radios in airplanes, ships, spacecraft, radar equipment, and navigation beacons. Transmitters typically generate radio waves for communication purposes; or radio positioning, such as radar and navigation transmitters. In this embodiment of the present invention, specifically, the signal transmitting device 108 is a wireless transmitter.

[0074] In this embodiment of the present invention, the signal receiving device 110 can be, but is not limited to, a receiver. In radio communications, a radio receiver (also referred to as a receiver) is an electronic device that receives radio waves and converts the information they carry into a usable form. Radio receivers are an important part of all systems that use radio. The information produced by the receiver can be in the form of sound, moving images (television), or digital data. A radio receiver can be a stand-alone electronic device, or an electronic circuit in another device. Radio receivers are very widely used in modem technology, such as televisions, mobile phones, wireless modems, and other components of communication, remote control, and wireless network systems. In this embodiment of the present invention, specifically, the signal receiving device 110 is a wireless receiver.

[0075] In this embodiment of the invention, the power supply device 112 can be, but is not limited to, a battery. For example, a car battery is a rechargeable battery used to start a motor vehicle; its main purpose is to provide current to the electric starter motor, which in turn starts the chemically powered internal combustion engine that actually propels the vehicle; once the engine is running, power for the vehicle's electrical system is still provided by the battery, with the alternator charging the battery as demand increases or decreases. In addition, an electric vehicle battery is a battery used to power the electric motor of a battery electric vehicle or hybrid electric vehicle: these batteries are typically rechargeable (secondary) batteries, and are typically lithium-ion batteries. In this embodiment of the invention, specifically, the power supply device 112 is a vehicle battery.

[0076] In one embodiment of the present invention, the mounting housing 114 is configured to be mounted on a brake pad 116 of a vehicle brake assembly, and the light emitting device 106 is mounted on the mounting housing 114 according to one embodiment (hereinafter referred to as Figure 6In other embodiments, the mounting housing 114 is configured to be mounted to a brake pad 116 of a brake assembly of a vehicle, and the light emitting device 106 is mounted to a caliper 134 of the brake assembly (as described below with reference to FIG. Figure 6 For example, turning our attention to Figure 5 , showing a perspective view of the outer portion 154 and the inner portion 156 of the brake pad 116. It will be appreciated that the brake pad is comprised of a steel backing plate (e.g., the outer portion 154) and a friction material bonded to the surface of the steel backing plate that faces the disc brake rotor, and that a typical brake assembly for a standard vehicle has two brake pads per brake assembly for each wheel of the vehicle, with one brake pad of the brake assembly being closer to the inner portion of the wheel (i.e., the inner portion of the rotor 106) and the second brake pad of the brake assembly being closer to the outer portion of the wheel (i.e., the outer portion of the rotor 106). Thus, in accordance with the principles of the disclosed embodiments, the mounting housing 114 may be secured to the outer portion 154 (i.e., the steel backing plate) of the corresponding brake pad, with the inner portion 156 including the friction material that faces the rotor 106 and causes the vehicle to brake when the operator applies the brakes during normal driving. Figure 8 This configuration can be further understood in Figure 4 ), Figure 8 A front cross-sectional view of a brake assembly 146 is presented, showing the rotor 106, mounting housing 114, and sensing device 106 of the brake alert system 100 of the present invention in accordance with this embodiment. Advantageously, the brake alert system 100 in accordance with the principles of the disclosed embodiments may be configured as a kit assembly such that the system may be added to and used with any type of brake pad and brake assembly.

[0077] In one aspect of an embodiment of the present invention, the mounting shell 114 includes an arc-shaped plate 118 and a slot 120; the slot 120 crosses the arc-shaped plate 118; the arc-shaped plate 118 includes a first flat surface 122, a second flat surface 124 and a side curved convex surface 126; the first flat surface 122 and the second flat surface 124 are positioned opposite to each other; the side curved convex surface 126 is formed between the first flat surface 122 and the second flat surface 124; the side curved convex surface 126 is connected to the first flat surface along the outer periphery of the first flat surface 122; the side curved convex surface 126 is connected to the second flat surface 124 along the outer periphery of the second flat surface 124; the slot 120 crosses the first flat surface 122.

[0078] In this aspect of this embodiment of the present invention, the light-emitting device 106 includes a first light-emitting diode 128 and a second light-emitting diode 130; the first light-emitting diode 128 is attached to the side curved convex surface 126; the first light-emitting diode 128 is inserted into the side curved convex surface 126; the first light-emitting diode 128 is exposed on the side curved convex surface 126 in a visibly manner; the second light-emitting diode 130 is attached to the side curved convex surface 126; the second light-emitting diode 130 is inserted into the side curved convex surface 126; the second light-emitting diode 130 is exposed on the side curved convex surface 126 in a visibly manner; the first light-emitting diode 128 and the second light-emitting diode 130 are separated from each other via the groove 120.

[0079] Turning our attention to Figure 6 According to an embodiment of the present invention, Figure 1 and 2 1. A cross-sectional / side view of a brake assembly 146 configured with a brake pad 116 and a mounting housing 114 is shown. The brake assembly 146 includes a rotor 106, a brake pad 116, a caliper 134, a drain port 136, a dust cover 138, a piston seal 140, a piston 142, and a shock cable clip 144. It should be understood that the brake assembly 146 has a brake pad 116 divided / divided as by the slot 120, with a brake pad disposed adjacent each side of the rotor 106 so that when an operator of the vehicle engages each brake pad 116, a force will be applied to the rotor, thereby braking and slowing the vehicle. According to this embodiment, each brake pad 116 is configured with a respective mounting housing 114 including a first light emitting diode 128 and a second light emitting diode 130, as appropriate. The principles of the disclosed embodiments are equally applicable to any vehicle that uses a brake assembly with a brake pad, including but not limited to automobiles, trucks, semi-trailers, and motorcycles, to name a few.

[0080] In this embodiment of the present invention, the brake alarm system 100 is configured to be applied to the brake pads 116 to sense and detect the amount of current passing through the brake pads 116, and to generate a color code (green / yellow / red) indicating the condition of the brake pads 116 based on the current, thereby indicating the condition of the brake pads 116 based on the color code or providing an alarm that the brake pads 116 may need to be replaced.

[0081] When the mounting housing 114 is mounted on the brake pads 116 of the vehicle, the sensing device 104 is able to detect the current passing through the brake pads 116. The processor 102 then determines the amount of current and drives the light emitting device 106 to generate a color code (green / yellow / red), that is, enables or enables the light emitting device 106 to light up in the corresponding color. Therefore, the light emitting device 106 works as a color indicator that indicates the condition of the brake pads 116 based on the current. And people will be able to see these light colors around the brake pads 116 of the vehicle. For example, if Figure 6 As shown, the lighting device 106 (ie, the first LED 128 and the second LED 130 ) are visible (eg, to a mechanic or driver of the vehicle) when the brake assembly 146 is viewed through the caliper 134 structure.

[0082] Turn your attention to Figure 7 , which is a cross-sectional / side view of a brake assembly 148 with a brake pad 116 and mounting housing 114 configuration in which a light emitting device 106 is mounted directly on a caliper 134 of a brake assembly 148 according to an embodiment of the present invention. The brake assembly 148 includes a rotor 106, a brake pad 116, a caliper 134, a bleed port 136, a dust cover 138, a piston seal 140, a piston 142, and a shock cable clip 144. It should be understood that the brake assembly 148 has the brake pad 116 divided / divided, such as by the slots 120, with a brake pad disposed adjacent each side of the rotor 106 so that when an operator of the vehicle engages each brake pad 116, a force will be applied to the rotor, thereby braking and decelerating the vehicle. According to this embodiment, each brake pad 116 is provided with a respective mounting housing 114, and the first light emitting diode 128 and the second light emitting diode 130 are mounted directly on (e.g., on the outer surface of) the caliper 134 as appropriate. In this manner, the mounting housing is configured to be mounted on the brake pad of the brake assembly for generating a status indication according to the monitored wear condition communicated by the light emitting device.

[0083] In this way, Figure 3 As shown, the light emitting device 106 can emit a status indication using green light based on the monitored wear state, indicating that the brake pad 116 is in a "good" state; the light emitting device 106 can emit a yellow light based on the monitored wear state, indicating that the brake pad 116 is in a "not so good" state; the light emitting device 106 can emit a red light based on the monitored wear state, indicating that the brake pad 116 is in a "maintenance required" state, thereby providing an alarm that the brake pad 116 may need to be replaced. This indication is also applicable to the respective Figure 6 and Figure 7 Any brake assembly structure shown in .

[0084] In addition, if Fig. 9 As shown, the brake warning system 100 is configured to communicate (e.g., wirelessly) with an external user device 132 (e.g., a smartphone) via a signal transmitting device 108 and a signal receiving device 110 to provide information to a user associated with the external user device 132 and receive instructions from it. Therefore, in one embodiment, the brake warning system 100 generates and transmits an alarm message to the external user device 132 via the signal transmitting device 108 based on the status indication, indicating that the brake pads 116 require maintenance attention. For example, the processor 102 may generate a message "Alert! Brake pads require attention" and transmit the message to the external user device 132 via the signal transmitting device 108. Therefore, the user will be able to see the alarm on the external user device 132.
