Description

Technical Field

[0001] This utility model relates to the field of motor vehicle brake warning technology, and in particular to a brake warning screen. Background Technology

[0002] Currently, car brake lights are generally installed on both sides of the rear of the vehicle, connected to the taillights. When the vehicle in front brakes, the brake lights at the rear of the car illuminate to warn the driver behind and prevent rear-end collisions. Traditional brake lights only use two states—on and off—to warn the driver behind of the braking status of the vehicle in front. This warning method cannot determine whether the vehicle in front is slowing down normally or braking suddenly, making it difficult for the driver behind to predict the braking intensity, which can easily lead to misjudgment and rear-end collisions. Moreover, brake lights located on both sides of the vehicle are not very conspicuous during the day.

[0003] Patent application CN201721844455.7 discloses a vehicle brake light with improved warning effect, including a light-emitting element, a light controller, and a bracket disposed inside a vehicle taillight assembly. The bracket has a tapered blind hole, and the light-emitting element is installed in the blind hole. The light controller is mounted on the bracket and is signal-connected to the light-emitting element. The light-emitting element includes a primary aperture, a secondary aperture, and a tertiary aperture, which are arranged axially at intervals on the inner peripheral wall of the blind hole, with one side of the light source facing the lamp cover of the vehicle taillight assembly. The light controller sequentially sends commands to the primary aperture, the secondary aperture, and the tertiary aperture. This design gives the light a spiral lighting effect, thereby attracting the attention of vehicles or pedestrians behind, enhancing the visibility of the brake light, and thus improving the warning effect of the brake light.

[0004] Patent application CN201921752442.6 discloses an emergency braking warning light for automobiles. It adds an emergency braking warning function to the existing commonly used brake light circuit. During intermittent braking and light braking, the original brake light circuit remains unchanged. During emergency braking, the emergency brake lever on the brake pedal actuates the emergency brake compound limit switch. Its normally closed contact cuts off the power circuit to the brake switch, while its normally open contact energizes the three-terminal strobe light, causing the brake light to flash, warning following vehicles to slow down and avoid rear-end collisions. This solution has the significant advantages of simple structure and providing both a normal braking display and an emergency braking flashing mode for the brake light.

[0005] Patent application number CN201710233573.2 discloses a car emergency braking rear-end collision prevention system and a car. The car emergency braking rear-end collision prevention system includes a brake sensor, a controller, and a brake warning unit. The brake sensor is installed on the brake unit of the car and monitors whether the brake unit is in an emergency braking state. The brake sensor signal is connected to the controller to transmit the working status signal of the brake unit to the controller. The controller signal is connected to the brake warning unit, which is installed at the rear of the car. When the brake unit is in an emergency braking state, the controller controls the brake warning unit to activate to remind people behind the car. This solution can promptly and accurately reflect whether the driver is slowing down or braking suddenly, thereby reminding drivers of vehicles behind to prevent rear-end collisions.

[0006] While existing brake warning systems have improved upon traditional brake light warning structures, they still rely on light effects to warn drivers of following vehicles, failing to provide a direct visual indication of the braking status of the vehicle ahead. Therefore, this invention discloses a brake warning screen to address these issues. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0028] As described in the background section, current automotive brake lights are generally installed on both sides of the rear of the vehicle, connected to the taillights. When the vehicle in front brakes, the brake lights at the rear of the car illuminate to warn the driver of the following vehicle and prevent rear-end collisions. Traditional brake lights only use two states—on or off—to warn the driver of the vehicle in front of the braking status. This warning method cannot determine whether the vehicle in front is decelerating normally or braking suddenly, making it difficult for the driver of the following vehicle to predict the braking intensity, which can easily lead to misjudgment and rear-end collisions. Moreover, brake lights located on both sides of the vehicle are not very conspicuous during the day. Although existing brake warning systems have improved the traditional brake light warning structure, they still rely on light effects to warn the driver of the following vehicle, failing to provide a direct visual indication of the braking status of the vehicle in front.

[0029] To solve this technical problem, this utility model provides a brake warning screen, which is applied to the field of motor vehicle brake warning.

[0030] For details, please refer to Figure 1-3 The brake warning screen specifically includes a base plate 1, on which a brake status display module 3, a brake progress display module 4, and a brake warning module 5 are electrically connected to the vehicle computer 2; and a sensing module 6, which is electrically connected to the vehicle computer 2. The sensing module 6 is used to collect the brake status and display it in the brake status display module 3 and the brake progress display module 4 through the vehicle computer 2, and to warn following vehicles according to the brake warning module 5.

[0031] The brake warning screen provided by this utility model collects the braking status of the vehicle in front through the sensor module 6 and transmits the collected signal to the vehicle computer 2. The vehicle computer 2 displays the braking status signal in the brake status display module 3 and the brake progress display module 4, so that the driver of the following vehicle can clearly observe the braking situation of the vehicle in front. The brake warning module 5 provides a braking warning to the driver of the following vehicle, reducing rear-end collisions and improving driving safety.

[0032] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0033] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0034] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0035] Example 1

[0036] Please refer to Figure 1-3 A brake warning screen is provided, which includes a base plate 1. The base plate 1 is provided with a brake status display module 3, a brake progress display module 4 and a brake warning module 5 electrically connected to an on-board computer 2. The on-board computer 2 is also electrically connected to a sensor module 6, which is used to collect the brake status and display it in the brake status display module 3 and the brake progress display module 4 through the on-board computer 2, and warn the following vehicles according to the brake warning module 5.

[0037] In this example, substrate 1 is a transparent substrate, specifically transparent glass or polyimide board. During installation, substrate 1 is fixed to the rear of the car or the rear window. A transparent circuit layer, such as an indium tin oxide circuit layer, is provided on substrate 1 and electrically connected to the vehicle computer 2 to control the brake status display module 3, brake progress display module 4, and brake warning module 5. The vehicle computer 2 is the original vehicle computer. The controller in the vehicle computer 2 has a control program for controlling the brake status display module 3, brake progress display module 4, and brake warning module 5. This part is prior art and will not be described in detail here.

[0038] Both the brake status display module 3 and the brake progress display module 4 are electroluminescent sheets. Electroluminescence refers to the physical phenomenon where certain materials directly convert electrical energy into light energy under the influence of an electric field. In this example, thin-film electroluminescence is used, employing thinner, vapor-deposited or sputtered fluorescent material films (such as ZnS, Mn) with a more refined structure. Alternatively, organic electroluminescence can be used, employing small organic molecules or polymers as the light-emitting material (OLED). Under DC or pulsed DC driving, electrons and holes recombine within the organic layer to form excitons, which then de-excite light. This electroluminescent sheet excites the light-emitting material through an electric field, causing electrons and holes to recombine and directly release photons, allowing for extremely clear display of text and graphics. In this example, during braking, the brake status display module 3 displays "Light Braking," "Medium Braking," or "Heavy Braking," allowing following drivers to visually observe whether the preceding vehicle is braking lightly or suddenly, thus judging distance and improving driving safety. Alternatively, the brake status display module 3 can display "Braking in Progress" to provide a clear braking signal to following drivers.

[0039] The braking progress display module 4 is used to display the braking progress. Specifically, the braking progress display module 4 includes several color display blocks 41. The colors of the color display blocks 41 gradually deepen from left to right. In this example, there are five color display blocks 41. The colors of the color display blocks 41 gradually deepen from left to right, specifically from orange-yellow to bright red from the far left to the far right. As the colors deepen, the braking progress can be displayed more intuitively. The braking progress can be braking time or braking force, indicating the degree of braking. Furthermore, the braking progress display module 4 also includes a digital display block 42 for displaying the percentage of progress. The percentage displayed in the digital display block 42 matches the displayed color of the color display blocks 41. Using the digital display block 42, the braking progress of the braking progress display module 4 can be directly displayed, intuitively and clearly indicating the braking progress. Drivers of following vehicles can take corresponding measures in a timely manner based on the information displayed by the braking progress display module 4, reducing the occurrence of accidents.

[0040] Furthermore, the brake warning module 5 is a flashing light strip, which includes at least three individual LEDs 51. The LEDs 51 are Micro LEDs (micron-sized light-emitting diodes). The individual LEDs 51 flash alternately, using their flashing frequency to warn following vehicles. Naturally, the flashing frequency of the LEDs 51 increases with the force of braking. The LEDs 51 can display a single color or multiple colors, using striking colors such as red or yellow. The LEDs 51 in the light strip are controlled by the controller in the vehicle's onboard computer 2.

[0041] The back of the substrate 1 is provided with a transparent adhesive layer 7, and the front of the substrate 1 is provided with a transparent protective layer 8 covering the brake status display module 3, the brake progress display module 4 and the brake warning module 5. The transparent protective layer 8 is transparent glass, and the transparent protective layer 8 and the substrate 1 are sealed with transparent adhesive.

[0042] Example 2

[0043] The brake warning screen provided in Embodiment 1 has been further optimized, specifically, as follows: Figure 1 As shown, the sensing module 6 includes an acceleration sensor 61. The acceleration sensor is used to collect the unit deceleration value of the vehicle to determine the braking status of the vehicle. The acceleration sensor 61 is selected from the TE Connectivity 1201 series. When the vehicle in front brakes, the vehicle will decelerate. The on-board computer 2 determines the braking intensity (light, medium, or heavy) based on the deceleration acceleration. After the on-board computer 2 receives the signal from the acceleration sensor, the controller controls the braking status display module 3, the braking progress display module 4, and the braking warning module 5 through the transparent circuit layer to display the braking signal. At the same time, it controls the LED lights 51 in the light bar to flash at a certain frequency.

[0044] Example 3

[0045] The brake warning screen provided in Embodiment 2 has been further optimized, specifically, as follows: Figure 1 As shown, the sensing module 6 also includes a Hall effect brake travel sensor 62. The Hall effect brake travel sensor 62 is a Melexis MLX91377. The Hall effect brake travel sensor 62 is installed on the brake pedal and is used to detect the displacement of the brake pedal. This avoids misjudgment by a single acceleration sensor. For example, if the vehicle decelerates due to a bumpy road, the Hall effect brake travel sensor 62 is used to detect the pedal displacement with an accuracy of ±0.5mm, reducing brake misjudgment and improving brake judgment accuracy.

[0046] The working principle of the brake warning screen provided by this utility model is as follows: When the vehicle in front brakes, the acceleration sensor and Hall effect brake stroke sensor 62 monitor the vehicle's acceleration and the displacement of the brake pedal, and transmit the signals to the on-board computer 2. The on-board computer 2 processes the signals, and then displays the braking status of the vehicle in front intuitively in the brake status display module 3 and the brake progress display module 4 according to the braking intensity. This allows the driver of the following vehicle to clearly observe the braking situation of the vehicle in front, and provides a braking warning to the driver of the following vehicle through the brake warning module 5, thereby reducing rear-end collisions and improving driving safety.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
