Description

Technical Field

[0001] This invention relates to a vehicle light, and more particularly to a modular vehicle light with blind spot detection function. Background Technology

[0002] Vehicle blind spot detection (BSD) systems can generally be divided into two main market segments: the OEM market (factory-installed products; Original Equipment, OE) and the aftermarket market (aftermarket installed products; After Market, AM) where different products are selected and installed based on varying customer needs. Aftermarket blind spot detection systems require additional radar mounting on the vehicle body (e.g., on the bumper), necessitating rewiring, resulting in cumbersome wiring, aesthetically unappealing installation, complex procedures, and high labor costs. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a modular vehicle light with blind spot detection function to address the shortcomings of the prior art.

[0004] This invention discloses a modular vehicle headlight with blind spot detection function, suitable for installation on a vehicle, comprising: a headlight body; and a blind spot detector disposed in the headlight body, comprising: a radar detection unit that emits a radar detection signal to detect whether a moving object exists in a blind spot area of ​​the vehicle; and a wireless transmission unit coupled to the radar detection unit that wirelessly transmits a warning signal to a warning device of the vehicle when the radar detection unit detects the presence of the moving object in the blind spot area.

[0005] Preferably, the blind spot detector further includes a control unit and a motion detection unit. The control unit is coupled to the motion detection unit, the radar detection unit, and the wireless transmission unit. The motion detection unit detects whether the headlight body is moving, and when it detects movement of the headlight body, it sends a wake-up signal to the control unit. After receiving the wake-up signal, the control unit controls the radar detection unit to transmit the radar detection signal. When the radar detection unit detects the presence of the moving object in the blind spot area, the control unit controls the wireless transmission unit to wirelessly transmit the warning signal to the vehicle's warning device.

[0006] Preferably, the blind spot detector further includes a global positioning unit (GPS). The control unit is coupled to the GPS, the motion detection unit, the radar detection unit, and the wireless transmission unit. After receiving the wake-up signal, the control unit controls the radar detection unit to transmit the radar detection signal and simultaneously controls the GPS to receive a satellite signal. The control unit then calculates the vehicle speed using the received satellite signal. When the vehicle speed is greater than or equal to a speed threshold, the control unit controls the radar detection unit to continuously transmit the radar detection signal. When the vehicle speed is less than the speed threshold, the control unit stops the operation of the radar detection unit.

[0007] Preferably, the blind spot detector further includes an image acquisition unit. The control unit is coupled to the image acquisition unit, the motion detection unit, the radar detection unit, and the wireless transmission unit. After receiving the wake-up signal, the control unit controls the radar detection unit to transmit the radar detection signal. When the radar detection unit detects a moving object in the blind spot area, the control unit controls the image acquisition unit to acquire an image of the moving object to generate a corresponding image signal, and controls the wireless transmission unit to wirelessly transmit the image signal to the vehicle's warning device.

[0008] Preferably, the alarm device includes a wireless receiving unit, a visual alarm unit, and an auditory alarm unit, wherein the wireless receiving unit is coupled to the visual alarm unit and the auditory alarm unit respectively; after the wireless receiving unit wirelessly receives the alarm signal, the visual alarm unit is controlled to emit a visual alarm message, and the auditory alarm unit is controlled to emit an auditory alarm message.

[0009] Preferably, the alarm device further includes a vibration alarm unit, and the wireless receiving unit is coupled to the vibration alarm unit, the visual alarm unit and the auditory alarm unit respectively; after the wireless receiving unit wirelessly receives the alarm signal, the vibration alarm unit is controlled to emit a vibration alarm message.

[0010] Preferably, the headlight body has at least one lighting element, the blind spot detector is located in an area outside the lighting element of the headlight body, and the blind spot detector is coupled to the power supply of the lighting element of the headlight body.

Furthermore, the accompanying drawings of this invention are for simple illustrative purposes only and are not depictions of actual dimensions, as stated in advance. The following embodiments will further describe the relevant technical content of this invention in detail, but the disclosed content is not intended to limit the scope of protection of this invention. In addition, the term "or" used herein may, depending on the actual situation, include any combination of any one or more of the associated listed items.

[0019] Please see Figure 1 , Figure 2 and Figure 3 This invention provides a modular vehicle headlight (hereinafter referred to as modular headlight 100) with blind spot detection function, suitable for installation on a vehicle 700, which can be a car, a large truck, a large bus, etc., and two modular headlights 100 can be installed on the vehicle 700. For ease of explanation, only one modular headlight 100 will be described below. The modular headlight 100 of this embodiment basically includes a headlight body 1 and a blind spot detector 2.

[0020] The headlight body 1 can be a rear headlight body for mounting on the rear side of the vehicle 700. The headlight body 1 may have at least one lighting element 11, and the lighting element 11 may be, for example, an LED light, a xenon light, a halogen light, etc. Furthermore, the headlight body 1 may be a headlight body from the aftermarket, and its appearance outline may correspond to that of a headlight body from the OEM market.

[0021] The blind spot detector 2 is installed in the headlight body 1, and can be located in an area other than the lighting element 11 of the headlight body 1. It can be coupled to the power supply 12 of the lighting element 11 of the headlight body 1, and the power supply 12 can be derived from the alternator or battery of the vehicle 700. The blind spot detector 2, as... Figure 3 As shown, the system may include a radar detection unit 21 and a wireless transmission unit 22. The radar detection unit 21 is activated after the vehicle 700 is started, and it can emit a radar detection signal (such as millimeter wave or ultrasonic wave) using radar detection technology and receive the corresponding reflected signal to detect whether a moving object (such as a vehicle approaching from the rear) exists in a blind spot area 800 of the vehicle 700 (e.g., the area behind the vehicle, the inner wheel difference range generated when a large truck turns). The wireless transmission unit 22 is coupled to the radar detection unit 21. Furthermore, when the radar detection unit 21 detects a moving object in the blind spot area 800, the wireless transmission unit 22 can wirelessly transmit a warning signal to a warning device 900 of the vehicle 700 using wireless transmission technology, such as Bluetooth technology.

[0022] The warning device 900 for Vehicle 700 can be a factory-installed component, such as an in-vehicle head unit or digital instrument panel. Alternatively, the warning device 900 can be an aftermarket device, installed as part of a package system with the modular headlights 100, depending on the user's needs. The warning device 900, for example... Figure 3As shown, the device may include a wireless receiving unit 901, a visual warning unit 902, and an auditory warning unit 903. The warning device 900 may also include a vibration warning unit 904. The wireless receiving unit 901 is coupled to the visual warning unit 902, the auditory warning unit 903, and the vibration warning unit 904. The wireless receiving unit 901 can be a wireless receiver integrated with the processing unit but operating independently, or it can be a central processing unit of the vehicle 700 controlled along with other functional units. The wireless receiving unit 901 can wirelessly receive warning signals transmitted by the wireless transmitting unit 22 using wireless receiving technology, such as Bluetooth. After the wireless receiving unit 901 wirelessly receives the warning signal, the visual warning unit 902 is controlled to emit a visual warning message, the auditory warning unit 903 is controlled to emit an auditory warning message, and the vibration warning unit 904 is controlled to emit a vibration warning message. The visual warning unit 902 may be, for example, a warning light or a display, and the visual warning message may be a bright light, a flashing light, etc. The auditory warning unit 903 is, for example, a speaker or a buzzer, and the auditory warning information can be voice, beeping, etc. The vibration warning unit 904 is, for example, a vibration motor, and the vibration warning information can be high-frequency vibration. The warning device 900 can wirelessly receive the warning signal sent by the wireless transmitting unit 22 through the wireless receiving unit 901, and achieve the blind spot warning effect by emitting auditory warning information, visual warning information, or vibration warning information through the visual warning unit 902, the auditory warning unit 903, or the vibration warning unit 904. Therefore, the modular vehicle light 100 of this embodiment has a blind spot detector 2, and the blind spot detector 2 of the modular vehicle light 100 achieves the blind spot warning effect by sending warning signals to the warning device 900 of the vehicle 700 through wireless transmission technology, thereby eliminating the cumbersome wiring and effectively reducing construction complexity and labor costs.

[0023] In some embodiments, reference may be made to Figure 1 , 2 And can be further referenced. Figure 4The blind spot detector 2 of the modular headlight 100 may further include a control unit 23 and a motion detection unit 24. The control unit 23 is coupled to the motion detection unit 24, the radar detection unit 21, and the wireless transmission unit 22. The motion detection unit 24 may include one or a combination of a three-axis accelerometer and a three-axis gyroscope, thereby detecting whether the headlight body 1 is moving, or in other words, detecting whether the vehicle 700 is moving, and sending a wake-up signal to the control unit 23 when the headlight body 1 is detected to be moving. The control unit 23 may be, for example, a microcontroller (MCU) with relevant logic programs inside. According to the control logic, after receiving the wake-up signal, it can control the radar detection unit 21 to emit a radar detection signal, and when the radar detection unit 21 detects a moving object in the blind spot area 800 of the vehicle 700, it controls the wireless transmission unit 22 to wirelessly send a warning signal to the warning device 900 of the vehicle 700. Therefore, when vehicle 700 begins to move, modular headlight 100 can detect the movement of vehicle 700 and activate the radar detection function to detect whether there is a moving object in the blind spot area 800 of vehicle 700. When a moving object is detected in the blind spot area 800, a warning signal is wirelessly sent to the warning device 900 of vehicle 700. Therefore, the modular headlight 100 in this embodiment has its own motion detection function, which eliminates the need for motion detection wiring configuration on the vehicle itself, reducing construction complexity and labor costs.

[0024] In some embodiments, reference may be made to Figure 1 , 2 And can be further referenced. Figure 5The blind spot detector 2 of the modular headlight 100 may further include a Global Positioning System (GPS) 25. The control unit 23 is coupled to the GPS 25, motion detection unit 24, radar detection unit 21, and wireless transmission unit 22. Upon receiving a wake-up signal, the control unit 23 controls the radar detection unit 21 to transmit a radar detection signal, and simultaneously controls the GPS 25 to receive a satellite signal, calculating the vehicle speed 700 based on the received satellite signal. Furthermore, after receiving satellite signals from multiple satellites via the GPS 25, the control unit 23 uses triangulation to calculate the coordinate changes of the vehicle 700, thereby calculating the vehicle speed. Furthermore, when the vehicle speed of 700 is greater than or equal to a speed threshold, the control unit 23 controls the radar detection unit 21 to continuously emit radar detection signals. When the vehicle speed of 700 is less than the speed threshold, the control unit 23 stops the operation of the radar detection unit 21. The control unit 23 can also enter a sleep standby mode to save power after the vehicle 700 comes to a complete stop. Therefore, the modular headlight 100 in this embodiment has its own speed detection function, eliminating the need for separate speed detection wiring for the vehicle itself, thus reducing construction complexity and labor costs.

[0025] In some embodiments, reference may be made to Figure 1 , 2 And can be further referenced. Figure 6 The blind spot detector 2 of the modular headlight 100 may further include an image acquisition unit 26 (e.g., a camera). The control unit 23 is coupled to the image acquisition unit 26, the motion detection unit 24, the radar detection unit 21, and the wireless transmission unit 22. Upon receiving a wake-up signal, the control unit 23 controls the radar detection unit 21 to emit a radar detection signal. When the radar detection unit 21 detects a moving object in the blind spot area 800, it controls the image acquisition unit 26 to acquire an image of the moving object to generate a corresponding image signal, and controls the wireless transmission unit 22 to wirelessly transmit a warning signal and an image signal to the warning device 900 of the vehicle 700. The warning device 900 of the vehicle 700 can wirelessly receive the warning signal and image signal wirelessly transmitted by the wireless transmission unit 22 through the wireless receiving unit 901, and display the warning signal and image signal through the visual warning unit 902 (e.g., a digital instrument panel or central display) to achieve a blind spot warning effect. Therefore, the modular headlight 100 of this embodiment has its own image acquisition function, eliminating the need for the vehicle's own camera installation and related wiring configuration, reducing construction complexity and labor costs.

[0026] In summary, the modular vehicle headlight with blind spot detection function provided in this embodiment of the invention includes a headlight body and a blind spot detector. The blind spot detector is disposed in the headlight body. The blind spot detector includes a radar detection unit and a wireless transmission unit.
