The vehicle lamp comprises an outer lamp shell, a first inner lamp sleeve, a driving assembly, a lamp head assembly and a transmission matching piece. The driving assembly is arranged on the outer lamp shell and is in transmission connection with the first inner lamp sleeve. The transmission matching piece is arranged on the first inner lamp sleeve. One side of the transmission matching piece is in transmission cooperation with the outer lamp shell, and the other side of the transmission matching piece is in transmission cooperation with the lamp head assembly. When the driving assembly drives the first inner lamp sleeve to stretch out or retract relative to the outer lamp shell, the transmission matching piece drives the lamp head assembly to stretch out or retract relative to the first inner lamp sleeve. Thus, the two sides of the transmission matching piece are in transmission cooperation with the outer lamp shell and the lamp head assembly respectively. When the driving assembly drives the first inner lamp sleeve to stretch out or retract relative to the outer lamp shell, the transmission matching piece can drive the lamp head assembly to stretch out or retract relative to the first inner lamp sleeve. Therefore, the multi-stage stretching and retracting of the vehicle lamp can be realized, and the multi-stage stretching and retracting of the vehicle lamp is more simple and reliable.

[0039] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0040] The following is for reference. Figures 1-7 A vehicle headlight 100 according to an embodiment of the present invention is described. The headlight 100 can employ a headlight control method and can be applied to a vehicle.

[0041] Combination Figures 1-4As shown, the vehicle headlight 100 according to an embodiment of the present invention may mainly include: an outer lamp housing 10, a first inner lamp sleeve 20, a drive assembly 30, a lamp head assembly 40, and a transmission coupling member 50. The first inner lamp sleeve 20 is movably disposed within the outer lamp housing 10. The drive assembly 30 is disposed on the outer lamp housing 10 and is pulsatorically connected to the first inner lamp sleeve 20. The lamp head assembly 40 is movably disposed within the first inner lamp sleeve 20. The transmission coupling member 50 is disposed on the first inner lamp sleeve 20. One side of the transmission coupling member 50 is pulsatorically engaged with the outer lamp housing 10, and the other side is pulsatorically engaged with the lamp head assembly 40, so that when the drive assembly 30 drives the first inner lamp sleeve 20 to extend or retract relative to the outer lamp housing 10, it drives the lamp head assembly 40 to extend or retract relative to the first inner lamp sleeve 20.

[0042] Specifically, by placing the first inner lamp sleeve 20 inside the outer lamp housing 10 and placing the lamp head assembly 40 inside the first inner lamp sleeve 20, the outer lamp housing 10 can cover and protect the first inner lamp sleeve 20 and the lamp head assembly 40, preventing the erosion of external foreign objects and the impact of external forces from damaging the structure of the lamp head assembly 40, thereby ensuring the structural reliability of the lamp head assembly 40 and ensuring the realization of the basic lighting function of the vehicle's headlights 100.

[0043] Furthermore, the first inner lamp sleeve 20 is movably configured relative to the outer lamp housing 10. By setting the drive assembly 30 on the outer lamp housing 10, the drive assembly 30 is connected to the first inner lamp sleeve 20 in a transmission manner. In this way, the drive assembly 30 can drive the first inner lamp sleeve 20 to extend and retract relative to the outer lamp housing 10. Furthermore, by setting the transmission fitting 50 on the first inner lamp sleeve 20, one side of the transmission fitting 50 is in transmission engagement with the outer lamp housing 10, and the other side is in transmission engagement with the lamp head assembly 40. In this way, when the drive assembly 30 drives the first inner lamp sleeve 20 to extend and retract relative to the outer lamp housing 10, one side of the transmission fitting 50 can be in transmission engagement with the outer lamp housing 10, and the transmission fitting 50 can move relative to the outer lamp housing 10. The moving transmission fitting 50 can further be in transmission engagement with the lamp head assembly 40 on the other side, driving the lamp head assembly 40 to extend and retract relative to the first inner lamp sleeve 20. This enables multi-stage extension and retraction of the vehicle's headlight 100, and makes the implementation of multi-stage extension and retraction of the vehicle's headlight 100 simpler and more reliable.

[0044] In this way, the headlight 100 can have a retracted state and an extended state. When the headlight 100 is in the retracted state, the outer lamp housing 10, the first inner lamp sleeve 20, and the lamp head assembly 40 do not undergo relative displacement. When the headlight 100 is in the extended state, the first inner lamp sleeve 20 extends relative to the outer lamp housing 10, and the lamp head assembly 40 extends relative to the first inner lamp sleeve 20. This allows the user to switch the extension and retraction states of the headlight 100 according to actual needs, which can enhance the sophistication and technological feel of the headlight 100 and improve the user experience.

[0045] Combination Figure 3 and Figure 4 As shown, a first transmission part 11 is provided on the outer lamp housing 10, and a second transmission part 421 is provided on the lamp head assembly 40. The first transmission part 11 is located on one side of the transmission mating member 50 and is in transmission mating with the transmission mating member 50. The second transmission part 421 is located on the other side of the transmission mating member 50 and is in transmission mating with the transmission mating member 50. Specifically, by providing the first transmission part 11 on the outer lamp housing 10 and the second transmission part 421 on the lamp head assembly 40, one side of the transmission mating member 50 can be in transmission mating with the first transmission part 11, and the other side of the transmission mating member 50 can be in transmission mating with the second transmission part 421. This makes the transmission mating between the transmission mating member 50 and the outer lamp housing 10, as well as the transmission mating between the transmission mating member 50 and the lamp head assembly 40, more stable and reliable. This makes the transmission of power between the transmission mating member 50, the outer lamp housing 10, and the lamp head assembly 40 more stable and reliable, thereby further improving the stability and reliability of the more than 100-level extension and retraction of the vehicle lamp.

[0046] Furthermore, combined Figure 3 and Figure 4 As shown, the transmission engagement 50 is a transmission gear, the first transmission part 11 is a first rack part, and the second transmission part 421 is a second rack part. One side of the transmission gear meshes with the first rack part so that when the drive assembly 30 drives the first inner lamp sleeve 20 to extend and retract relative to the outer lamp housing 10, it drives the transmission gear to rotate. The other side of the transmission gear meshes with the second rack part so as to drive the lamp head assembly 40 to extend and retract relative to the first inner lamp sleeve 20. Specifically, the transmission engagement component 50 can be configured as a transmission gear, the first transmission part 11 as a first rack part, and the second transmission part 421 as a second rack part. By engaging one side of the transmission gear with the first rack part, when the drive assembly 30 drives the first inner lamp sleeve 20 to extend or retract relative to the outer lamp housing 10, the transmission gear can rotate while following the first inner lamp sleeve 20 in a linear motion relative to the outer lamp housing 10. Furthermore, by engaging the other side of the transmission gear with the second rack part, the power of the transmission gear can be transmitted to the second rack part, converting the rotational motion of the transmission gear into the linear motion of the second rack part, thereby driving the lamp head assembly 40 to extend or retract relative to the first inner lamp sleeve 20. In this way, the transmission efficiency and transmission stability of the transmission engagement component 50 with the first transmission part 11 and the second transmission part 421 can be improved, thereby further improving the efficiency and stability of the vehicle's multi-stage extension and retraction.

[0047] Combination Figure 3 and Figure 4As shown, a through hole 23 is provided on the side wall of the first inner lamp sleeve 20. The transmission gear is disposed in the through hole 23. At least a part of the transmission gear extends out from one side of the through hole 23 and meshes with the first rack portion. At least a part of the transmission gear extends out from the other side of the through hole 23 and meshes with the second rack portion. With this arrangement, while ensuring that both sides of the transmission gear mesh with the first rack portion and the second rack portion respectively, and that the lamp head assembly 40 can extend and retract relative to the first inner lamp sleeve 20 when the drive assembly 30 drives the first inner lamp sleeve 20 to extend and retract relative to the outer lamp housing 10, the through hole 23 not only facilitates the placement of the transmission gear on the first inner lamp sleeve 20, but also accommodates at least a part of the transmission gear. This avoids the transmission gear occupying too much volume in the vehicle lamp 100 and improves the structural compactness of the vehicle lamp 100.

[0048] Combination Figure 3 and Figure 4 As shown, there are at least two transmission coupling components 50, which are spaced apart on the circumferential sidewall of the first inner lamp sleeve 20. Specifically, by setting at least two transmission coupling components 50, at least two transmission coupling components 50 can simultaneously engage with the lamp head assembly 40 to transmit power to the lamp head assembly 40. Furthermore, by spaced apart on the circumferential sidewall of the first inner lamp sleeve 20, the power transmitted to the lamp head assembly 40 by the at least two transmission coupling components 50 can be more evenly distributed, thereby further improving the stability and reliability of the extension and retraction of the lamp head assembly 40 relative to the first inner lamp sleeve 20, and further improving the reliability of the vehicle lamp 100.

[0049] Combination Figure 3 and Figure 4 As shown, the drive assembly 30 mainly includes a drive member 31 and a transmission member 32. The drive member 31 is disposed at the bottom of the outer lamp housing 10, and the transmission member 32 is disposed on the drive member 31. A third transmission part 221 is disposed at the bottom of the first inner lamp sleeve 20, and the transmission member 32 is in a transmission engagement with the third transmission part 221. Specifically, by disposing the drive member 31 at the bottom of the outer lamp housing 10, the drive assembly 30 can be stably installed. By disposing the transmission member 32 on the drive member 31, the power of the drive member 31 can be output through the transmission member 32. Furthermore, by disposing the third transmission part 221 at the bottom of the first inner lamp sleeve 20, and by engaging the transmission member 32 with the third transmission part 221, the power of the drive member 31 can be transmitted to the first inner lamp sleeve 20 sequentially through the transmission member 32 and the transmission part, thereby driving the first inner lamp sleeve 20 to extend and retract relative to the outer lamp housing 10. This makes the extension and retraction of the first inner lamp sleeve 20 relative to the outer lamp housing 10 simpler and more reliable.

[0050] Furthermore, combined Figure 3 and Figure 4As shown, the first inner lamp sleeve 20 mainly includes: an inner lamp sleeve body 21 and a transmission bar 22. The transmission bar 22 is disposed at the bottom of the inner lamp sleeve body 21, the lamp head assembly 40 is disposed inside the inner lamp sleeve body 21, and the transmission bar 22 is provided with a third transmission part 221. Specifically, by disposing of the transmission bar 22 at the bottom of the inner lamp sleeve body 21, disposing of the lamp head assembly 40 inside the inner lamp sleeve body 21, and providing a third transmission part 221 on the transmission bar 22, when the drive assembly 30 is disposed at the bottom of the first inner lamp sleeve 20, the drive assembly 30 can easily and quickly achieve transmission cooperation with the third transmission part 221, improving transmission efficiency. Furthermore, while ensuring the transmission cooperation between the first inner lamp sleeve 20 and the drive assembly 30, the design of the transmission bar 22 can achieve the weight reduction of the first inner lamp sleeve 20.

[0051] Combination Figures 1-4 As shown, the vehicle headlight 100 may further include: an opening / closing member 60, which is rotatably mounted on the headlight assembly 40. The opening / closing member 60 is slidably engaged with the first inner lamp sleeve 20. The top of the opening / closing member 60 covers a portion of the headlight assembly 40, thereby changing the area of ​​the headlight assembly 40 covered by the opening / closing member 60 when the headlight assembly 40 extends or retracts relative to the first inner lamp sleeve 20. Specifically, the opening / closing member 60 is rotatably mounted on the headlight assembly 40, and the top of the opening / closing member 60 can cover a portion of the headlight assembly 40. By sliding the opening / closing member 60 with the first inner lamp sleeve 20, when the first inner lamp sleeve 20 extends or retracts relative to the outer lamp housing 10, the first inner lamp sleeve 20 can drive the opening / closing member 60 to rotate relative to the headlight assembly 40, thereby changing the area of ​​the headlight assembly 40 covered by the opening / closing member 60. This allows for the concealment or exposure of the headlight assembly 40, enabling the transformation of the headlight 100 and further enhancing its technological and sophisticated appearance.

[0052] Combination Figure 3 and Figure 4 As shown, the opening / closing component 60 mainly includes: an opening / closing piece 61 and a mating rod 62. The top of the mating rod 62 is connected to the outer edge of the opening / closing piece 61. The mating rod 62 is pivotally mounted on the lamp head assembly 40. The mating rod 62 is provided with a sliding groove 621. The first inner lamp sleeve 20 is provided with an inwardly protruding sliding part 24. The sliding part 24 is engaged in the sliding groove 621. Thus, when the first inner lamp sleeve 20 extends or retracts relative to the outer lamp housing 10, the sliding part 24 on the first inner lamp sleeve 20 can slide and engage with the sliding groove 621 on the mating rod, causing the mating rod 62 to move relative to the lamp head assembly 40, thereby causing the opening / closing piece 61 to rotate relative to the lamp head assembly 40. This makes the rotation of the opening / closing component 60 relative to the lamp head assembly 40 more stable and reliable.

[0053] Furthermore, combined Figure 3 and Figure 4As shown, the slide 621 can mainly include: a first groove segment 6211 and a second groove segment 6212. The extension direction of the first groove segment 6211 is the same as the extension and retraction direction of the lamp head assembly 40. The second groove segment 6212 is connected to the bottom of the first groove segment 6211, and the second groove segment 6212 extends outward in the direction of extending to the bottom. Specifically, the second groove segment 6212 is connected to the bottom of the first groove segment 6211. When the vehicle lamp 100 is in the retracted state, the sliding part 24 cooperates with the first groove segment 6211. When the vehicle lamp 100 is in the extended state, the sliding part 24 cooperates with the second groove segment 6212. By making the extension direction of the first groove segment 6211 the same as the extension and retraction direction of the lamp head assembly 40, and making the second groove segment 6212 extend outward in the direction of extending to the bottom, when the lamp head assembly 40 extends relative to the first inner lamp sleeve 20, the sliding part 24 can first cooperate with the first groove segment 6211. With mutual sliding cooperation, the opening and closing part 60 extends out relative to the first inner lamp sleeve 20 along with the lamp head assembly 40. Then, the sliding part 24 can slide and cooperate with the second groove segment 6212. The sliding part 24 drives the cooperating rod 62 to rotate relative to the lamp head assembly 40. At the same time as the opening and closing part 60 extends out relative to the first inner lamp sleeve 20 along with the lamp head assembly 40, the opening and closing part 60 opens relative to the lamp head assembly 40. Thus, the coverage area of ​​the opening and closing part 60 on the lamp head assembly 40 can be different in different states of the vehicle light 100, which can further enhance the refinement and technological feel of the vehicle light 100.

[0054] Combination Figure 1 and Figure 2 As shown, there are multiple opening and closing components 60, which are spaced apart around the circumference of the lamp head assembly 40, and multiple opening and closing pieces 61 are connected sequentially in a ring. Specifically, by setting multiple opening and closing components 60 and arranging them spaced apart around the circumference of the lamp head assembly 40, and connecting them sequentially in a ring, the placement of the opening and closing components 60 conforms to the structure of the lamp head assembly 40. This allows the opening and closing components 60 to more effectively cover the area of ​​the lamp head assembly 40, further enhancing the sophistication of the vehicle headlight 100.

[0055] Furthermore, combined Figure 3 and Figure 4 As shown, the lamp head assembly 40 mainly includes: a lamp head 41 and a second inner lamp sleeve 42, the second inner lamp sleeve 42 being fitted onto the lamp head 41, a second transmission part 421 being disposed on the second inner lamp sleeve 42, and an opening / closing member 60 being rotatably disposed on the second inner lamp sleeve 42. Specifically, by fitting the second inner lamp sleeve 42 onto the lamp head 41, the second inner lamp sleeve 42 can be used for transmission engagement with the transmission mating member 50, and the opening / closing member 60 can be conveniently disposed on the lamp head assembly 40, thereby protecting the structure of the lamp head 41, improving the structural stability of the lamp head 41, and further improving the structural reliability of the vehicle lamp 100.

[0056] Combination Figure 5 As shown, the control method for the vehicle headlight 100 according to an embodiment of the present invention can be applied to the vehicle headlight 100 of the above-described vehicle, and the control method for the vehicle headlight 100 may include the following steps:

[0057] S1. Determine the vehicle speed V and the preset speed V. 设 Relationship;

[0058] S2, when V≤V 设 When the drive assembly 30 is working, the lamp head assembly 40 extends from the initial position to the preset position;

[0059] S3, when V > V 设 At this time, the lamp head assembly 40 retracts to its initial position.

[0060] Specifically, when controlling the vehicle headlight 100 using the control method for the vehicle headlight 100, it is first necessary to determine the relationship between the vehicle speed and the preset speed, and then control the extension and retraction of the lamp head assembly 40 according to the different relationships between the vehicle speed and the preset speed. When the vehicle speed is not greater than the preset speed, the drive assembly 30 is energized, driving the lamp head assembly 40 to extend from the initial position to the preset position, thereby realizing the intelligent extension, retraction, and deformation of the headlight 100. When the vehicle speed is greater than the preset speed, the lamp head assembly 40 is controlled to retract to the initial position. This prevents the lamp head assembly 40 from extending to the preset position when the vehicle is traveling at high speed, thereby not only reducing the vehicle's driving resistance but also preventing high-speed fluid from impacting the headlight 100, thus improving the structural stability of the headlight 100. It should be noted that the lamp head assembly 40 can also operate according to the braking signal, so that the headlight 100 illuminates immediately when the vehicle brakes, serving as a warning to pedestrians. In a specific embodiment of the present invention, the preset speed can be 10 km / h.

[0061] In some embodiments of the present invention, combined with Figure 6 As shown, step S2 may include the following steps:

[0062] S2-1. Determine the speed range in which the engine speed n falls;

[0063] S2-2, n When the first rotation speed range is reached, the lamp head assembly 40 extends to the first preset position;

[0064] S2-3, n When the second rotation speed range is reached, the lamp head assembly 40 extends to the second preset position;

[0065] When S2-4 and n are in the third speed range, the lamp head assembly 40 extends to the third preset position, wherein the third speed range is higher than the second speed range, and the second speed range is higher than the first speed range, the third preset position is farther than the second preset position, and the second preset position is farther than the first preset position.

[0066] Specifically, when the vehicle speed is less than or equal to a preset speed, and the drive assembly 30 operates to drive the lamp head assembly 40 to extend from the initial position to the preset position, the specific preset position of the lamp head assembly 40 can also be designed in conjunction with the engine speed. The engine speed range can include a first speed range, a second speed range, and a third speed range, with the third speed range being higher than the second speed range, and the second speed range being higher than the first speed range. Similarly, the preset position of the lamp head assembly 40 can include a first preset position, a second preset position, and a third preset position, with the third preset position being farther than the second preset position, and the second preset position being farther than the first preset position.

[0067] Thus, when adjusting the extension and retraction position of the lamp head assembly 40 in conjunction with the engine speed, it is first necessary to determine the engine speed range. When the engine speed is in the first speed range, the lamp head assembly 40 extends to the first preset position; when the engine speed is in the second speed range, the lamp head assembly 40 extends to the second preset position; and when the engine speed is in the third speed range, the lamp head assembly 40 extends to the third preset position. In this way, the vehicle lamp 100 can adjust the preset position of the lamp head assembly 40 according to different engine speed ranges, making the extension and retraction of the vehicle lamp 100 more intelligent, adapting the vehicle lamp 100 to different driving scenarios, thereby enhancing the technological feel and sophistication of the vehicle lamp 100, and improving the user experience.

[0068] In other embodiments of the invention, combined with Figure 7 As shown, step S2 may include the following steps:

[0069] S2-5. Determine the speed range in which the engine speed n falls;

[0070] S2-6, n When the speed range is first, the brightness of the lamp head assembly 40 is the first brightness;

[0071] S2-7, n When the speed range is second, the brightness of the lamp head assembly 40 is the second brightness;

[0072] When S2-8 and n are in the third speed range, the brightness of the lamp head assembly 40 is the third brightness, wherein the third speed range is higher than the second speed range, and the second speed range is higher than the first speed range, the third brightness is greater than the second brightness, and the second brightness is greater than the first brightness.

[0073] Specifically, when the vehicle speed is less than or equal to a preset speed, and the drive assembly 30 operates to drive the lamp head assembly 40 to extend from its initial position to a preset position, the specific brightness of the lamp head assembly 40 can also be designed in conjunction with the engine speed. The engine speed range can include a first speed range, a second speed range, and a third speed range, where the third speed range is higher than the second speed range, and the second speed range is higher than the first speed range. The brightness of the lamp head assembly 40 can have a first brightness, a second brightness, and a third brightness, where the third brightness is greater than the second brightness, and the second brightness is greater than the first brightness.

[0074] Therefore, when adjusting the brightness of the lamp head assembly 40 in conjunction with the engine speed, it is first necessary to determine the engine speed range. When the engine speed is in the first speed range, the brightness of the lamp head assembly 40 is the first brightness; when the engine speed is in the second speed range, the brightness of the lamp head assembly 40 is the second brightness; and when the engine speed is in the third speed range, the brightness of the lamp head assembly 40 is the third brightness. In this way, the vehicle lamp 100 can adjust the brightness of the lamp head assembly 40 according to different engine speed ranges, making the brightness adjustment of the vehicle lamp 100 more intelligent and adaptable to the lighting requirements of different driving scenarios. This makes the vehicle lamp 100 more practical and improves the user experience.

[0075] In one specific embodiment of the present invention, when n≤1000r / min, the engine speed is in the first speed range; when 1000<n≤3000r / min, the engine speed is in the second speed range; and when 3000<n≤5000r / min, the engine speed is in the third speed range.

[0076] In another specific embodiment of the present invention, when the lamp head assembly 40 is in the first preset position, the first inner lamp sleeve 20 and the lamp head assembly 40 move by one-third of their respective maximum strokes, and the opening and closing member 60 does not open. When the lamp head assembly 40 is in the second preset position, the first inner lamp sleeve 20 and the lamp head assembly 40 move by two-thirds of their respective maximum strokes, and the opening and closing member 60 opens by 7° relative to the lamp head assembly 40. When the lamp head assembly 40 is in the third preset position, the first inner lamp sleeve 20 and the lamp head assembly 40 move by their respective maximum strokes, and the opening and closing member 60 opens by 12.5° relative to the lamp head assembly 40, and the opening and closing member 60 reaches its maximum opening and closing position.

[0077] According to embodiments of the present invention, a vehicle may primarily include: the vehicle headlights 100 described above. Specifically, by applying the headlights 100 to a vehicle and employing a control method for controlling the headlights 100, the headlights 100 can achieve intelligent extension, retraction, and deformation, thereby enhancing the vehicle's sophistication and technological feel, and improving the user experience.
