Description

Technical Field

[0001] This disclosure relates to the field of electronic equipment technology, and in particular to a blind spot light, a blind spot monitoring system, and a vehicle. Background Technology

[0002] Blind Spot Detection (BSD) systems use sensors such as millimeter-wave radar and cameras to monitor the blind spots to the sides and rear of the vehicle, acquiring information such as target position, relative speed, and direction of travel. Once a vehicle is detected in the blind spot or approaching from behind at high speed, the system alerts the driver through warning signals on the side mirrors and through sound and light. Figure 1 The diagram shown is a schematic of the blind spot monitoring system monitoring the blind spot area behind the vehicle.

[0003] When changing lanes, vehicles cannot fully assess the situation of vehicles behind them based solely on the information in the rearview mirrors due to blind spots in the rearview mirrors. In particular, adverse weather conditions (rain, snow, fog, hail, etc.) increase the difficulty of judgment for the driver, raising the risk of collisions or scrapes during lane changes.

[0004] Blind spot monitoring systems rely on sensors and controllers. Sensors include millimeter-wave radar mounted on either side of the vehicle's rear bumper, or high-resolution cameras. These sensors can detect target vehicles within a certain range and analyze their motion. The controller processes the sensor data, determines whether a warning is needed, and provides real-time feedback to the driver via actuators such as blind spot lights on the rearview mirrors or displays on the dashboard.

[0005] Blind spot monitoring systems are mainly divided into two types based on technology: image blind spot monitoring systems and radar blind spot monitoring systems. Each of these two technologies has its own advantages and disadvantages.

[0006] Regarding the blind spot monitoring system: It monitors the blind spots of the vehicle by installing cameras on the vehicle. The cameras are mainly installed on the side mirrors or the rear of the vehicle to monitor whether there are vehicles coming from behind the vehicle in the form of images. However, the image technology will not perform well in bad weather (rain, snow, fog, etc.) and is prone to misjudgment.

[0007] Regarding the radar blind spot monitoring system: The radar used in the radar blind spot monitoring system is mainly 24GHz and 77GHz shortwave radar. The radar is installed on the side of the vehicle or the rear bumper. By emitting microwaves, it detects vehicles approaching from the sides and rear of the vehicle, and can know information such as the distance, speed and direction of movement of the vehicles behind. Through the system algorithm, stationary objects and distant objects are excluded. When a vehicle is detected approaching in the blind spot, the indicator light flashes. At this time, the driver cannot see the vehicle in the blind spot, but can know from the indicator light that a vehicle is approaching from behind and there is a risk of collision if he changes lanes. If the driver still does not notice the flashing indicator light and turns on the turn signal to prepare to change lanes, the system will issue a voice alarm to remind the driver again that changing lanes is dangerous and should not be done.

[0008] Blind Spot Detection (BSD) systems cover not only passenger vehicles but also pedestrians, electric vehicles, bicycles, and other moving objects to the side and rear. In addition to basic blind spot detection, BSD systems offer various auxiliary functions such as Lane Change Assist (LCA), Drive-Out Assist (DOW), and Reverse Cross Traffic Alert (RCTA), effectively preventing accidents in scenarios such as lane changing, door opening, and reversing across obstacles.

[0009] Existing BSD (Blind Spot Detector) lights mostly use direct LED illumination. The main problem with this approach is uneven light projection, with the center of the LED being too bright and areas further away being too dark, resulting in poor display quality and negatively impacting the user experience. To improve light uniformity, reflectors are used in related technologies. By reflecting the light emitted by the LEDs, the uniformity of the light is significantly improved. However, this approach increases the number of structural components and raises the product cost. Utility Model Content

[0075] It should be noted that these accompanying drawings and textual descriptions are not intended to limit the scope of the present invention in any way, but rather to illustrate the concept of the present invention to those skilled in the art by referring to specific embodiments. Detailed Implementation

[0076] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0077] Figure 1 This diagram illustrates a blind spot detection system provided in an embodiment of this application that monitors the blind spot area to the side and rear of a vehicle. The Blind Spot Detection (BSD) system uses sensors such as millimeter-wave radar and cameras to monitor the blind spot area to the side and rear of the vehicle, acquiring information such as the target's position, relative speed, and direction of travel. Once a vehicle 100 is detected in the blind spot or approaching the vehicle from behind at a high speed, the driver is alerted by flashing the blind spot light 1 mounted on the rearview mirror 2 of the vehicle 100. In related technologies, the blind spot light 1 is mostly a direct LED light. The main problem with this approach is that the projected light is uneven; the center of the blind spot light window is too bright, while the edges are too dark, resulting in poor display quality and negatively impacting the user experience.

[0078] To solve the above technical problems, such as Figures 2 to 24 As shown, this application provides a blind spot lamp 1, including: a housing 11 and a circuit board 12. The housing 11 has a cavity and an opening communicating with the cavity, as shown in the figure. Figure 6 As shown, the inner wall of the cavity has a main reflection area 111, a first reflection area 112, and a second reflection area 113, with the first reflection area 112 and the second reflection area 113 located on opposite sides of the main reflection area 111. A circuit board 12 is connected to the housing 11, and the circuit board 12 is located on the opening side, as shown... Figure 15 and Figure 16 As shown, the circuit board 12 covers an opening, and a lamp body 121 is mounted on the circuit board 12. The lamp body 121 is positioned opposite the main reflector area 111. The lamp body 121 can be an LED lamp. The main reflector area 111 is located directly below the LED lamp, close to one side wall 1201 of the cavity. The main reflector area 111 has a reflective spherical surface, and the total area of ​​the reflective spherical surface is approximately one-quarter of that of a complete sphere. The light beam from the LED light hits the main reflector 111, which reflects the light beam. Some beams are reflected directly to one side of the opening, while others are reflected onto the side wall 1201. After secondary reflection, some beams enter the opening, while others are reflected to the first reflector 112 and the second reflector 113. The main function of the main reflector 111 is to reduce the light intensity in the central area of ​​the LED and increase the light intensity in the edge area of ​​the LED, making the light projected from the light-transmitting window 2 as uniform as possible. The function of the first reflector 112 and the second reflector 113 is to further disperse the incident light, which helps to improve the light energy utilization rate and makes the light reflection more uniform. That is, while improving the light energy utilization rate, the light reflection is made more uniform.

[0079] In some possible implementations, the housing 11 can be a one-piece molded housing 11, meaning that the main reflective area 111, the first reflective area 112, and the second reflective area 113 in the housing 11 are not located on other separate reflectors, but are directly molded onto the housing 11, thereby reducing the number of parts in the blind spot lamp 1, reducing assembly steps and production costs, and improving production efficiency. The first reflective area 112, the second reflective area 113, and the main reflective area 111 can each include several convex arc-shaped structures, and the housing 11 can be a one-piece injection molded part, directly forming each of the first reflective area 112, the second reflective area 113, and the main reflective area 111.

[0080] It should be noted that a reflective layer may be applied to the first reflective area 112, the second reflective area 113, and the main reflective area 111 to enhance the reflective effect. The reflective layer may be an electroplated layer applied to each of the convex curved surfaces.

[0081] In some possible implementation schemes, combined Figure 7 and Figure 8 As shown, the first reflective area 112 and the second reflective area 113 are both disposed on the bottom wall of the cavity, forming a first included angle between them, which protrudes away from the opening. That is, the bottom wall of the cavity is approximately concave. The first reflective area 112 and the second reflective area 113 are located on both sides of the main reflective area 111. The first reflective area 112 reflects light, reflecting some light to the opening and some light to the second reflective area 113. The second reflective area 113 also reflects some light to the opening and some light to the first reflective area 112. The first reflective area 112 and the second reflective area 113 work together to reflect light more evenly, making the light brightness on the opening side uniform and avoiding the problem of local overbrightness.

[0082] like Figure 16 As shown, the LED light beam hits the first reflective area 112, where small protrusions reflect the beam. Part of the beam is reflected directly to one side of the opening, and part is reflected to the sidewall 1201. After secondary reflection, part of the beam hits the opening, and part is reflected to the main reflective area 111 and the second reflective area 113. After secondary reflection, part of the beam is incident on one side of the opening. The main function of the first reflective area 112 is to balance the light intensity in the left section of the blind spot lamp 1, increasing the light intensity in the edge area through reflection, and making the light projected from one side of the opening as uniform as possible. The structure and principle of the second reflective area 113 are the same as those of the first reflective area 112, and will not be described further in this application.

[0083] Combination Figures 7 to 14As shown, the bottom wall of the cavity can be composed of multiple inclined surfaces or formed by an arc surface. For example, both the first reflective area 112 and the second reflective area 113 are arc surfaces.

[0084] In this embodiment, the beam projected from the open side has better uniformity due to the combined reflection of the main reflection area, the first reflection area 112, and the second reflection area 113.

[0085] In some possible implementations, such as Figure 8 As shown, the outer wall of the housing 11 has a bottom surface 1202, the bottom surface 1202 and the opening are located on opposite sides of the housing 11, the first reflective area 112 and the bottom surface 1202 have a second included angle α, the second reflective area 113 and the bottom surface 1202 have a third included angle β, and both the second included angle α and the third included angle β are not greater than 20°.

[0086] The bottom surface 1202 can be a flat surface, serving as the mating surface between the housing 11 and the mounting part, and as a reference surface for the blind spot lamp 1. The bottom surface 1202 can be attached to the bottom wall of the corresponding mounting groove on the exterior rearview mirror 2. Preferably, both the second and third included angles are no greater than 15°, resulting in better uniform reflection of the first reflection area 112 and the second reflection area 113.

[0087] In some possible implementations, the cavity includes a bottom wall and side walls 1201. A first reflective area 112 and a second reflective area 113 are both disposed on the bottom wall, forming a boundary line between them. The main reflective area 111 is located on the boundary line. Both the first reflective area 112 and the second reflective area 113 include multiple protrusions, each with an outwardly convex arc surface. This outwardly convex arc surface design disperses and reflects incident light, reducing localized intense light and making the reflected light more uniform.

[0088] In some possible implementations, the size of each protrusion in the first reflective area 112 gradually increases in the direction from the dividing line to the sidewall 1201, and the size of each protrusion in the second reflective area 113 gradually increases.

[0089] Among the protrusions in the first reflection zone 112 and the second reflection zone 113, the protrusions closer to the side wall 1201 are larger, which has a better light reflection effect and helps to improve the light energy utilization rate. The protrusions closer to the middle dividing line are smaller, which helps to disperse strong light more evenly. The larger protrusions on the side closer to the side wall 1201 can further disperse and reflect the light in a larger area, making the light reflection more uniform, thereby improving the light energy utilization rate and making the light reflection more uniform.

[0090] In some possible implementation schemes, combined Figure 17 and Figure 18As shown, the housing 11 is provided with a slot 114 and a positioning post 115, and the circuit board 12 has a positioning hole 122. When the circuit board 12 is connected to the housing 11, the positioning hole 122 is fitted onto the positioning post 115, and the circuit board 12 is partially inserted into the slot 114. The slot 114 is a stepped groove that extends a certain length along the edge of the opening, and the two ends of the slot 114 along the length direction are baffles. During assembly, first, the positioning hole 122 on the circuit board 12 is aligned with the positioning post 115, and then the circuit board 12 is placed over the opening side of the housing 11, so that the circuit board 12 is partially located in the slot 114. Due to the limiting effect of the baffles at both ends of the slot 114, the circuit board 12 can no longer rotate or move, thereby improving the assembly structure stability of the circuit board 12.

[0091] A cable 13 is connected to the circuit board 12. When the circuit board 12 is installed on the housing 11, the cable 13 needs to be led out of the housing 11, and the lead-in part needs to be sealed. In related technologies, a waterproof plug is added to achieve the sealing of the cable 13. The waterproof plug is used to seal the gap formed at the cable 13. The shortcomings of the waterproof plugging solution are very obvious. The main reasons include adding a component, which increases the cost; adding two processes, assembling the cable harness with the plug and assembling the plug with the cable outlet hole of the housing 11, which is time-consuming and labor-intensive. Moreover, when the cable harness is pulled, the cable harness may move relative to the plug, which may damage the cable harness solder joints.

[0092] Combination Figure 19 and Figure 20 As shown in the embodiment of this application, an adhesive-containing groove 118 can be provided on the outer wall of the housing 11, and a lead hole 119 communicating with the cavity is opened on the inner wall of the adhesive-containing groove 118. The cable 13 on the circuit board 12 extends out of the housing 11 through the lead hole 119, and the adhesive-containing groove 118 is filled with adhesive 14.

[0093] In this embodiment, the adhesive tank 118 is filled with adhesive 14, that is, filled with sealant, thereby sealing the gaps in the inner wall of the cable 13 and the lead hole 119 to achieve a certain level of dustproof and waterproof effect. The sealing effect is good, and it has a fixing effect on the cable 13, preventing the cable 13 from moving relative to the housing 11, which could lead to the problem of the wire harness breaking at the solder joint when external force is applied to the cable 13.

[0094] In some possible implementations, such as Figure 21 As shown, a lead wire notch 116 is provided on the edge of the opening on the housing 11. A cable 13 is connected to the circuit board 12, which covers the housing 11. The cable 13 extends out of the housing 11 through the lead wire notch 116. The design of the lead wire notch 116 avoids the cable 13 and facilitates the cable 13 to extend smoothly out of the housing 11.

[0095] In this embodiment, an outer groove 117 is formed on the outer wall of the housing 11. A lead wire notch 116 connects the cavity and the outer groove 117. A circuit board 12 covers the lead wire notch 116 and extends to the opening and the outer groove 117 respectively. The circuit board 12 and the outer groove 117 enclose a glue-containing cavity. The opening of the glue-containing cavity is located on the side away from the cavity. The cable 13 passes through the glue-containing cavity. The glue-containing cavity is filled with glue 14, that is, filled with sealant, thereby sealing the gap between the cable 13 and the inner wall of the outer groove 117, which can achieve a certain level of dustproof and waterproof.

[0096] If wiring holes are provided on the housing 11, the cable 13 needs to be manually threaded through the holes. This threading process will greatly reduce the product assembly efficiency. In this application, a lead wire notch 116 is provided on the housing 11. When the circuit board 12 is covered on the housing 11, the cable 13 will pass through the lead wire notch 116, saving the time-consuming and laborious threading process and significantly improving the assembly efficiency.

[0097] In some possible implementation schemes, combined Figure 17 and Figure 18 As shown, the housing 11 includes a partition 120 located within the cavity, with both ends connected to the inner wall of the housing 11. The partition 120 divides the cavity into a first cavity and a second cavity. The bottom wall of the first cavity is provided with a main reflective area 111, a first reflective area 112, and a second reflective area 113. Several components are disposed on the circuit board 12. When the circuit board 12 is mounted on the housing 11, it covers the top opening of the second cavity, and the components are accommodated within the second cavity, preventing interference between the components and the housing 11. A lead wire notch 116 is formed on one side of the top opening of the second cavity.

[0098] In some possible implementation schemes, combined Figures 3 to 5 As shown, the blind spot lamp 1 also includes a protective film 15, an outer adhesive backing 16, a diffuser 17, and an inner adhesive backing 18. The housing 11, circuit board 12, inner adhesive backing 18, diffuser 17, outer adhesive backing 16, and protective film 15 are arranged sequentially. Light-transmitting portions are provided on the circuit board 12, outer adhesive backing 16, and inner adhesive backing 18. These components are sequentially attached and connected, forming a window for the blind spot lamp 1. When these parts are assembled together, they form a complete blind spot lamp 1. After the lamp body 121 on the circuit board 12 is lit, the light is reflected by the inner wall of the housing 11, forming a uniformly bright area at the window.

[0099] This application also provides a blind spot monitoring system, including: a sensor, a computing circuit, and the aforementioned blind spot lamp 1. The computing circuit is electrically connected to the circuit board 12 of both the sensor and the blind spot lamp 1. The sensor sends the detected data to the computing circuit, which processes the data and controls the blind spot lamp 1 to turn on or off based on the processing result.

[0100] The sensor can be a camera, radar, or other detection structure. It can be installed on the rearview mirror 2 or the rear of the vehicle 100 to monitor whether there are vehicles approaching from behind the vehicle 100, and to control the illumination of the blind spot light 1 through the computing circuit to warn vehicles approaching from the side. The computing circuit may include a control circuit board. The control circuit board can be unique to the blind spot monitoring system, or it can reuse the original control circuit board on the vehicle 100.

[0101] like Figure 1 As shown, the blind spot monitoring system is mainly used to address potential safety hazards caused by blind spots in the rearview mirror 2. It has three core functions. The first core function is blind spot vehicle 100 monitoring. Using radar sensors or infrared cameras, it monitors the dynamic blind spots within approximately 3 meters to the sides and 8 meters behind the vehicle 100 in real time. When another vehicle 100 enters this area, the system alerts the driver through an audible alarm and flashing blind spot lights 1. The second core function is lane change collision warning. If the driver attempts to change lanes without noticing the vehicle 100 in the blind spot, the blind spot monitoring system can serve as a warning. The third core function is adverse environment assistance. It can still operate stably in rainy or foggy weather, at night, or when the rearview mirror 2 is affected by strong light, compensating for visual limitations.

[0102] like Figure 1 As shown, this application also provides a vehicle 100, including: a vehicle body and the aforementioned blind spot monitoring system, the vehicle body having a rearview mirror 2. The blind spot monitoring system is disposed on the vehicle body, such as the calculation circuit of the blind spot monitoring system being disposed on the vehicle body. The blind spot lamp 1 of the blind spot monitoring system is disposed on the rearview mirror 2, such as the exterior rearview mirror 2.

[0103] The rearview mirror 2 may include a main body and a reflector 21. The blind spot light 1 may be installed on the main body, and the reflector 21 may cover the main body. The reflector 21 is equipped with an alarm icon 211 at the location corresponding to the blind spot light 1.
