[0014] The controller is electrically connected to a pressure sensor, which is used to detect the braking force of the brake pedal.

[0015] Implementing this utility model has the following beneficial effects:

[0016] According to this embodiment, the roof trunk with brake warning system arranges at least two sets of brake lights at the rear of the trunk body and uses a vehicle speed detector to monitor vehicle speed changes in real time. The system then controls the illumination of the brake lights accordingly based on the vehicle speed changes. This allows for different brake warning lights to be displayed to following vehicles from the roof trunk location, effectively improving the warning effect of the vehicle's brake light system.

[0020] Figure 4 This is a simplified diagram showing the connection between the vehicle speed detection component and the brake light assembly in one embodiment of this utility model. Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, a further detailed description of this utility model will be provided below in conjunction with the accompanying drawings. It is hereby declared that any use of terms such as "up," "down," "left," "right," "front," "back," "inner," and "outer" in this document is based solely on the accompanying drawings and is not intended to specifically limit the scope of this utility model.

[0022] The roof box with brake warning provided by this utility model can provide different brake warning light reminders for following vehicles, effectively improving the warning effect of the brake light system on following vehicles and further ensuring driving safety.

[0023] In one embodiment of this utility model, such as Figures 1 to 4 As shown, the roof box with brake warning includes a box body 3. At least two sets of brake lights 51 are arranged at the rear of the box body 3. A vehicle speed detection device 52 is provided at the front of the box body 3. The vehicle speed detection device 52 is electrically connected to the at least two sets of brake lights 51. The vehicle speed detection device 52 is used to monitor the vehicle's driving speed and, according to the change in the vehicle's driving speed, controls one set of brake lights 51 to light up or controls at least two sets of brake lights 51 to light up and flash.

[0024] According to this embodiment of the roof trunk with brake warning system, at least two sets of brake light assemblies 51 are arranged at the rear of the trunk body 3. A vehicle speed detection device 52 detects changes in vehicle speed in real time and controls the illumination of the brake light assemblies 51 accordingly. This allows for different brake warning light alerts to following vehicles from the roof trunk location, effectively improving the warning effect of the vehicle's brake light system. Following drivers can more intuitively understand the braking intention and urgency of the vehicle in front, thus reacting in advance to avoid rear-end collisions and further ensuring driving safety.

[0025] In addition, since the roof box is generally installed at a high position, the brake signal emitted by the brake light assembly 51 located at the rear of the box body 3 can enter the field of vision of vehicles further behind earlier, thereby providing a certain braking warning to vehicles further behind, which can reduce the occurrence of chain-reaction rear-end collisions to some extent.

[0026] In one specific embodiment, such as Figure 1 and Figure 2 As shown, the roof rack can be equipped with three sets of brake lights 51, which are arranged along the width of the roof rack 3 at the rear of the roof rack 3. When the vehicle speed detector 52 detects that the vehicle speed is decreasing, but the decrease is small, it indicates that the vehicle in front is gradually decelerating. The vehicle speed detector 52 then controls one of the brake lights 51 on the left or right side to illuminate, providing a warning signal to the following vehicle that the vehicle in front is gradually braking and decelerating.

[0027] When the vehicle speed detection unit 52 detects that the vehicle speed has decreased and the decrease is significant, it indicates that the vehicle in front is decelerating urgently. The vehicle speed detection unit 52 then controls the three sets of brake lights 51 to illuminate simultaneously and flash rapidly to provide a warning signal to the vehicle behind that the vehicle in front is braking rapidly.

[0028] Specifically, such as Figure 3As shown, the brake light assembly 51 includes a lamp housing 512, a lamp cover (not shown), a circuit board, and multiple light source components 511. The lamp housing 512 has a mounting groove 513, and the lamp cover is embedded in the mounting groove 513. The multiple light source components 511 are arranged in an array in the mounting groove 513 to provide uniform and bright brake light when the light source is lit, ensuring the warning effect of the brake light system on following vehicles. The circuit board is located on the side of the lamp housing 512 opposite to the mounting groove 513. The light source components 511 and the vehicle speed detection component 52 are electrically connected to the circuit board, so that the electrical connection between the vehicle speed detection component 52 and the light source components 511 can be realized through the circuit board. This facilitates the transmission of the vehicle speed data detected by the vehicle speed detection component 52 to the circuit board, and after processing by the circuit board, it controls the multiple light source components 511 to emit light accordingly.

[0029] Preferably, the light source 511 is an LED light.

[0030] Furthermore, such as Figure 1 and Figure 3 As shown, the bottom wall of the mounting groove 513 has a reflective surface 514, and the reflective surface 514 is provided with a reflector. The reflector is red so that when the light source 511 shines on the bottom wall of the mounting groove 513, the color of the reflected light can be changed to red after being reflected by the reflector, further ensuring the warning effect of the light source 511 when it shines out of the lampshade.

[0031] The lamp cover is a light-transmitting panel to ensure that the light emitted by the lamp source 511 can be transmitted to the outside, making it easier for drivers of following vehicles to receive the corresponding warning information. The surface of the lamp cover has a grid pattern to increase its aesthetics and, to some extent, prevent the light from the lamp source 511 from being too glaring, thus affecting the driving safety of following vehicles.

[0032] In this embodiment, the vehicle speed detection component 52 is an acceleration sensor, which is used to monitor the real-time driving speed of the vehicle and ensure the stability and accuracy of vehicle speed detection.

[0033] In this embodiment, as Figure 4 As shown, the roof box with brake warning also includes a controller 53, which is electrically or signal-connected to the vehicle speed detector 52 and at least two sets of brake lights 51. When the vehicle speed detector 52 detects a decrease in vehicle speed, it can transmit the corresponding detection signal to the controller 53, which then controls one set of brake lights 51 to illuminate or at least two sets of brake lights 51 to illuminate and flash.

[0034] Preferably, the controller 53 is a programmable LED controller.

[0035] Furthermore, the controller 53 is connected to a pressure sensor, which is used to detect the braking force of the brake pedal. The degree of brake pedal depression detected by the pressure sensor is used in conjunction with the vehicle speed detection status of the vehicle speed detection device 52 to further control the lighting status of the brake light assembly 51.

[0036] For example, when the pressure sensor detects that the braking force of the brake pedal is small, the vehicle speed decreases only slightly, and the controller 53 controls one of the brake light groups 51 to light up accordingly; while when the pressure sensor detects that the braking force of the brake pedal is large, the vehicle speed decreases significantly, and the controller 53 controls at least two of the brake light groups 51 to light up and flash, thereby providing different braking warnings to following vehicles.

[0037] Specifically, the pressure sensor can be fixed to the back of the brake pedal with screws and a sealing ring. The signal line of the pressure sensor is connected to the signal input terminal of the controller 53 to ensure that the pressure sensor can accurately detect the pressure applied to the brake pedal.

[0038] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this invention, and these improvements and modifications are also considered to be within the protection scope of this utility model.
