Description

Technical Field

[0001] This application relates to the field of automotive lighting technology, and more particularly to a lamp, an automotive lighting system and its control method, a storage medium and an electronic device. Background Technology

[0002] For safety reasons, vehicles are equipped with front bumper beams. These beams absorb energy and provide a counter-force during a collision, reducing damage to the vehicle's longitudinal beams. For this reason, headlights generally cannot be placed in front of the bumper beam. This is because it would affect the energy absorption effect of the beam, and the significant counter-force provided by the bumper beam during a collision could compress and damage the headlights.

[0003] To improve the vehicle's appearance, some lights may need to be installed directly in front of the front bumper beam. In the event of a minor collision between the vehicle and a pedestrian, in order to comply with regulations, it is necessary to avoid accidents that could cause fractures in the lower leg of a pedestrian due to a minor collision. Therefore, the headlights installed on the front bumper beam need to have their internal structure optimized to provide better cushioning during a collision.

[0004] Furthermore, existing headlights consist of a fixedly connected lens and housing. After prolonged use, moisture can easily seep into the headlight through the gap between the lens and housing, accumulating inside. If this moisture isn't removed promptly, it will severely impact the headlight's lifespan. Removing accumulated moisture requires detaching the headlight from the vehicle and separating the lens and housing, which is time-consuming. Additionally, the high temperature between the lens and housing during normal operation also shortens the headlight's lifespan. Summary of the Invention

[0019] Furthermore, the step of driving the telescopic component to switch between the retracted state and the extended state based on the temperature and humidity sensor specifically includes:

[0068] Lighting fixtures:

[0069] The lighting fixtures in the embodiments of this application, such as Figure 1 , 2 As shown, it includes a lamp housing 01, a lamp shade 02 mounted on the opening of the lamp housing 01, and a light-emitting element 03 mounted in the lamp housing 01, and also includes...

[0070] Telescopic component 04 is disposed on the end of the lamp housing 01 away from the lamp cover 02, and has a retracted state and an extended state, see [reference]. Figure 2 In the extended state, the telescopic component 04 extends away from the lampshade 02;

[0071] Pressure sensor 05 is installed between lamp cover 02 and lamp housing 01 to sense the pressure of lamp cover 02 in the direction of lamp housing 01.

[0072] Control unit 06 is used to control telescopic component 04 to switch between retracted and extended states based on pressure sensor 05.

[0073] Specifically, the side with the opening of the lamp housing 01 is the front, and the side away from the opening is the rear. That is, the direction in which the light of the lamp is emitted is the front, and the light-emitting element 03 is installed in the lamp housing 01 and emits light in the front.

[0074] The opening of the lamp housing 01 extends outward to form a connecting portion 11, which is perpendicular to the front-back direction of the lamp. The lamp shade 02 includes a light-emitting surface 21 and a cover portion 22 extending from the light-emitting surface 21 toward the lamp housing 01. The cover portion 22 has a stepped surface 221 perpendicular to the front-back direction of the lamp. A pressure sensor 05 is installed between the stepped surface 221 and the connecting portion 11 to monitor the pressure on the lamp in the front-back direction.

[0075] The telescopic component 04 is located at the rear end of the lamp housing 01. Figure 1 and Figure 2An example of the telescopic component 04 in the retracted state and the extended state is shown respectively. When the telescopic component 04 is in the retracted state, the rear surface of the lamp housing 01 is flat or concave to the front. When the telescopic component 04 is in the extended state, the rear surface of the lamp housing 01 bulges to the rear, and the internal space of the lamp is larger than the internal space of the lamp when it is in the retracted state.

[0076] The control unit 06 can control the telescopic component 04 to switch from the retracted state to the extended state, and also control the telescopic component 04 to switch from the extended state to the retracted state. Under normal conditions, the telescopic component 04 is in the retracted state. When the pressure detected by the pressure sensor 05 increases, the control unit 06 controls the telescopic component 04 to switch to the extended state.

[0077] The lamp in this embodiment is configured with an expandable lamp housing structure, suitable for installation on the anti-collision beam 1 of a vehicle (see...). Figure 1 , 2 When the vehicle is impacted, the pressure sensor 05 detects an instantaneous increase in pressure. The control unit 06 can control the telescopic component 04 to extend backward and contact the anti-collision beam 1. The lamp expands backward to provide buffering force, which can effectively absorb energy and protect internal light-emitting components such as the light-emitting component 03 from damage.

[0078] In one embodiment, controlling the telescopic component to switch between a retracted state and an extended state based on a pressure sensor specifically includes:

[0079] If the pressure detected by the pressure sensor 05 is greater than or equal to the preset pressure threshold, the telescopic component 04 is controlled to switch to the extended state.

[0080] In this embodiment of the application, a preset pressure threshold is set. When the pressure detected by the pressure sensor 05 is greater than or equal to the preset pressure threshold, it is considered that the lamp has been impacted by an external force. Then, the telescopic component 04 is controlled to switch to the extended state to protect the lamp.

[0081] In one embodiment, such as Figure 1-3 As shown, the lamp housing 01 is provided with a mounting port 12 for mounting the telescopic component 04;

[0082] The telescopic component 04 includes a flexible extension portion 41 and a rigid connection portion that are alternately connected radially in the mounting port 12. During the switching between the extended state and the retracted state of the telescopic component 04, the flexible extension portion 41 is at least partially folded or stretched.

[0083] Specifically, the flexible extension part 41 is used to realize the extension and retraction of the telescopic component 04, and the rigid connection part is used to improve the rigidity of the rear end of the lamp housing 01, so as to improve the support force when extended. Figure 2As shown, when the telescopic component 04 is in the extended state, the flexible extension part 41 is fully extended, which drives the rigid connecting part connected between the flexible extension parts 41 to move backward.

[0084] As an example, the telescopic component 04 can be formed by two-color injection molding of flexible material and PP material, with the flexible material being the flexible extension part 41 and the PP material being the rigid connection part.

[0085] Optionally, the telescopic component 04 can be manufactured and installed into the mounting port 12, or it can be integrally molded with the lamp housing 01.

[0086] In one embodiment, such as Figure 1-3 As shown, the rigid connection includes at least one central plate 42, on which a first magnet 44 is mounted;

[0087] A second magnet 45 is installed between the lamp housing 01 and the lamp shade 02, which is opposite to the first magnet 44. The first magnet 44 and / or the second magnet 45 are electromagnets.

[0088] The control unit 06 is electrically connected to the pressure sensor 05 and the electromagnet, respectively, and is used to control the first magnet 44 and / or the second magnet 45 and the magnetic changes and / or magnetic pole changes according to the pressure sensor 05 to drive the first magnet 44 and the second magnet 45 to move relative to each other.

[0089] The central plate 42 is located at the center of the telescopic member 04, and the flexible extension 41 is annular and connected to the outer periphery of the central plate 42. The telescopic member 04 includes at least one central plate 42 and one flexible extension 41, with the flexible extension 41 connected to the outer periphery of the central plate 42.

[0090] like Figure 3 As shown, the telescopic component 04 of this application embodiment has a rigid connection portion including a central plate 42, a rigid connecting ring 43, and two flexible extension portions 41. One flexible extension portion 41 connects the central plate 42 and the rigid connecting ring 43, and the other flexible extension portion 41 connects the rigid connecting ring 43 and the mounting opening 12 of the lamp housing 01. In this application embodiment, the central plate 42 is configured as a quadrilateral, and both the flexible extension portion 41 and the rigid connecting ring 43 are quadrilateral rings. Optionally, the central plate 42 can also be configured as a circle or other shapes, and the flexible extension portion 41 and the rigid connecting ring 43 can be configured as circular rings or other annular shapes.

[0091] In this embodiment, the extension and retraction of the telescopic component 04 are controlled by a first magnet 44 and a second magnet 45 arranged opposite to each other. For example, the first magnet 44 is a permanent magnet and the second magnet 45 is an electromagnet.

[0092] The control unit 06 can control the magnetism of the second magnet 45 by controlling the on / off state of the power supply to the second magnet 45; it can also control the magnetic poles of the second magnet 45 by controlling the direction of the power supply to the second magnet 45.

[0093] like Figure 4 As shown, by passing a direct current in the first direction (arrow direction in the diagram) into the second magnet 45, the south pole of the second magnet 45 and the south pole of the first magnet 44 face each other, generating a repulsive force that pushes the first magnet 44 away from the second magnet 45, thus driving the telescopic member 04 to extend. Conversely, passing a direct current in the second direction, opposite to the first direction, can drive the telescopic member 04 to retract.

[0094] In one embodiment, such as Figure 4 As shown, the lamp also includes a temperature and humidity sensor 07 installed inside the lamp housing 01 or lamp shade 02;

[0095] Control unit 06 is also used to drive telescopic component 04 to switch between retracted and extended states based on temperature and humidity sensor 07.

[0096] In this embodiment, a temperature and humidity sensor 07 is installed on the side of the lamp housing 01 near the lamp shade 02 or inside the lamp shade 02 to detect the temperature and humidity inside the lamp. By monitoring the temperature and humidity, it is determined whether the temperature inside the lamp is too high or whether there is fogging. If it is determined that the temperature is too high or there is fogging, the telescopic component 04 is controlled to switch between the retracted state and the extended state to allow air circulation and achieve the effect of cooling and defogging.

[0097] It should be noted that, in order for the telescopic component 04 to extend and retract smoothly, a vent hole 13 is provided on the lamp housing 01 or lamp shade 02.

[0098] In one embodiment, the step of switching the telescopic component 04 between a retracted state and an extended state based on the temperature and humidity sensor 07 specifically includes:

[0099] If the temperature detected by temperature and humidity sensor 07 is greater than or equal to the preset temperature threshold, or

[0100] If the humidity detected by temperature and humidity sensor 07 is greater than or equal to the preset humidity threshold, then...

[0101] The telescopic component 04 is controlled to cycle between the retracted and extended states.

[0102] In this embodiment, a preset temperature threshold is set to determine whether the lamp temperature is too high, and a preset humidity threshold is set to determine whether the lamp fogs up. When it is determined that the lamp temperature is too high or fogs up, the telescopic component 04 is controlled to cycle between the retracted state and the extended state. The telescopic cycle can be preset to control the lamp to expand and contract evenly.

[0103] Headlight system:

[0104] The technical solution of this application also provides a vehicle lighting system, such as Figure 4 As shown, the system includes a vehicle electronic control system 08 and a lamp as described in any of the foregoing embodiments. The vehicle electronic control system 08 is communicatively connected to the control unit of the lamp. Specifically, the vehicle electronic control system 08 is communicatively connected to the control unit 06 of the lamp.

[0105] The vehicle electronic control system 08 is specifically the vehicle computer, which can receive detection signals from the obstacle detection radar 09 and operation signals input by the user through the central control system. The vehicle electronic control system 08 controls the lights through the lighting control unit 06 in combination with the vehicle's status, thereby realizing intelligent control of the vehicle lights.

[0106] Control methods for vehicle lighting systems:

[0107] The control method for the vehicle lighting system in the foregoing embodiments described in this application is as follows: Figure 5 As shown, including

[0108] Step S501: Obtain the distance between the obstacle in front of the vehicle and the vehicle, and the detection pressure of the pressure sensor;

[0109] Step S502: If the distance to the obstacle is less than or equal to a preset distance threshold, or

[0110] If the detected pressure is greater than or equal to the preset pressure threshold, then step S503 is executed;

[0111] Step S503: Control the telescopic component to switch to the extended state.

[0112] Specifically, when the vehicle is running, step S501 is executed to obtain the obstacle distance and detection pressure in real time. The obstacle distance is obtained through the vehicle's electronic control system 08, and the obstacle can be a vehicle or a pedestrian. Step S502 determines whether the obstacle distance is less than or equal to a preset distance threshold and whether the detection pressure is greater than or equal to a preset pressure threshold. If either condition is met, the telescopic component 04 is controlled to switch to the extended state.

[0113] In this embodiment, when the distance to an obstacle is less than or equal to a preset distance threshold, the vehicle electronic control system 08 controls the telescopic component 04 to extend via the control unit 06, causing the lamp to expand and thus providing collision pre-defense, reducing the time required for the lamp to expand upon actual collision. Additionally, when the detected pressure is greater than or equal to a preset pressure threshold, i.e., upon collision, the telescopic component 04 is also controlled to extend, achieving real-time defense.

[0114] In one embodiment, the luminaire further includes a temperature and humidity sensor 07 installed in the lamp housing 01 or lamp shade 02 for monitoring the temperature and humidity inside the luminaire.

[0115] like Figure 6 As shown, the control method further includes

[0116] Step S601: Obtain the detected temperature and detected humidity of the temperature and humidity sensor;

[0117] Step S602: If the detected temperature of the temperature and humidity sensor is greater than or equal to a preset temperature threshold, or

[0118] The humidity detected by the temperature and humidity sensor is greater than or equal to a preset humidity threshold, or

[0119] If a defogging and cooling signal is received, then step S603 is executed;

[0120] Step S603: Control the telescopic component to cycle between the retracted state and the extended state.

[0121] In this embodiment, when the detected temperature is greater than or equal to a preset temperature threshold, the lamp temperature is considered too high. When the detected humidity is greater than or equal to a preset humidity threshold, the lamp internal humidity is considered too high, which may cause fogging or pose a risk of fogging. In this case, the telescopic component 04 is controlled to cycle between the retracted state and the extended state to achieve uniform breathing of the lamp, thereby reducing the lamp temperature and humidity.

[0122] Meanwhile, users can input defogging and cooling signals through the vehicle's central control screen and other means. When the vehicle's electronic control system 08 receives the defogging and cooling signal, it controls the telescopic component 04 to cycle between the retracted state and the extended state to achieve the effect of active defogging and cooling.

[0123] In a preferred embodiment of this application, a first magnet is installed on the telescopic component, and a second magnet is installed between the lamp housing and the lamp shade, which is opposite to the first magnet. The first magnet is a permanent magnet, and the second magnet is an electromagnet.

[0124] Figure 7 A flowchart illustrating the control method for the vehicle lighting system is shown, specifically including...

[0125] Step S701: Obtain the distance between the obstacle in front of the vehicle and the vehicle, the detection pressure of the pressure sensor, and the detection temperature and humidity of the temperature and humidity sensor;

[0126] Step S702: If the distance to the obstacle is less than or equal to a preset distance threshold, or

[0127] If the detected pressure is greater than or equal to the preset pressure threshold, then step S703 is executed;

[0128] Step S703: Apply a DC power supply in the first direction to the second magnet;

[0129] Step S704: If the detected temperature of the temperature and humidity sensor is greater than or equal to a preset temperature threshold, or

[0130] The humidity detected by the temperature and humidity sensor is greater than or equal to a preset humidity threshold, or

[0131] If a defogging and cooling signal is received, then step S705 is executed;

[0132] Step S705: Cyclicly supply DC power in the first direction and DC power in the second direction to the second magnet.
