Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and in particular to a method, device, vehicle, and storage medium for controlling vehicle taillights. Background Technology

[0002] Headlights are a crucial component of vehicles, primarily serving functions such as illumination and warning. With technological advancements, headlight designs have become increasingly diverse and personalized. Beyond illumination and warning, well-designed headlights can also enhance the overall aesthetics of a vehicle and its competitiveness. Taillights are another important part of headlights, mainly serving a warning function during driving, such as indicating the vehicle's position and braking status to vehicles behind, thus ensuring driving safety.

[0003] However, while various automakers currently offer a wide variety of taillight designs, they are mostly based on fixed structures. This means the taillight structure cannot deform, preventing dynamic taillight displays and resulting in a lack of overall technological sophistication and intelligence, leading to a less than ideal user experience. Furthermore, the warning function relies solely on illuminating the taillights to alert following vehicles, making the warning limited and ineffective, thus impacting driving safety. Additionally, in the event of a collision with a following vehicle, the fixed taillight structure prevents deformation and retraction, making it impossible to avoid or mitigate damage to the taillights, thus compromising their safety. Summary of the Invention

[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. Therefore, the object of the present invention is to provide a method, device, vehicle, and storage medium for controlling vehicle taillights.

[0005] This invention proposes a control method for vehicle taillights. The taillight includes a lamp head assembly, a retractable mechanism, and a flip-up cover. The retractable mechanism drives the lamp head assembly to extend and retract. The flip-up cover is disposed on the lamp head assembly to adjust the occlusion area of ​​the lamp head assembly when the flip-up cover is opened or closed. The control method includes the following steps: acquiring vehicle status information; determining whether the vehicle meets the conditions for entering the intelligent taillight collision avoidance mode based on the vehicle status information; if so, controlling the vehicle to enter the intelligent taillight collision avoidance mode to acquire obstacle information behind the vehicle, and controlling the shape of the lamp head assembly based on the obstacle information through the retractable mechanism and the flip-up cover.

[0006] According to an embodiment of the present invention, a vehicle taillight control method acquires vehicle status information and determines whether the vehicle meets the conditions for entering the intelligent taillight collision avoidance mode. When the vehicle meets the conditions for entering the intelligent taillight collision avoidance mode, the method controls the vehicle to enter the intelligent taillight collision avoidance mode. Under the intelligent taillight collision avoidance mode, the method acquires information about obstacles behind the vehicle and, based on the obstacle information, controls the shape of the lamp head assembly through a retractable mechanism and a flip cover. For example, the retractable mechanism controls the extension and retraction of the taillight, and the flip cover adjusts the occlusion area of ​​the lamp head assembly, thereby reducing the concealed area of ​​the lamp head assembly. The taillights undergo dynamic changes, resulting in a cool and dynamic transformation that enhances the vehicle's intelligence and technological feel, improving the user experience. The dynamic transformation also strengthens the warning effect to vehicles behind, thus improving driving safety. Furthermore, because the taillight structure can dynamically deform, the lamp head assembly can extend, retract, and change its hidden area under the drive of the telescopic mechanism and the flip-up cover. Therefore, in the event of a collision with a following vehicle, the retracting and hiding of the lamp head assembly can effectively avoid or reduce damage to the taillights, thereby improving taillight safety.

[0007] In addition, the vehicle taillight control method according to embodiments of the present invention may also have the following additional technical features:

[0008] Furthermore, based on the obstacle information, the shape of the lamp head assembly is controlled by the retractable mechanism and the flip cover, including: determining whether there is an obstacle within a preset range behind the vehicle; if so, obtaining the distance between the obstacle and the taillight; and controlling the shape of the lamp head assembly by the retractable mechanism and the flip cover based on the distance between the obstacle and the taillight.

[0009] Furthermore, based on the distance between the obstacle and the taillight, the shape of the lamp head assembly is controlled by the retractable mechanism and the flip cover, including: if the distance between the obstacle and the taillight is greater than or equal to a first preset distance and less than or equal to a second preset distance, the retractable mechanism is controlled to drive the lamp head assembly to a first preset position or drive the lamp head assembly to remain at the first preset position, and the flip cover is controlled to be in a closed state.

[0010] Furthermore, based on the distance between the obstacle and the taillight, the shape of the lamp head assembly is controlled by the retractable mechanism and the flip cover, including: if the distance between the obstacle and the taillight is greater than the second preset distance, the retractable mechanism is controlled to drive the lamp head assembly to a second preset position or to drive the lamp head assembly to remain in the second preset position, and the flip cover is controlled to open to a first preset angle, wherein the second preset position and the first preset position are located on the same side of the preset retraction position, and the distance between the second preset position and the preset retraction position is greater than the distance between the first preset position and the preset retraction position.

[0011] Furthermore, based on the distance between the obstacle and the taillight, the shape of the lamp head assembly is controlled by the retractable mechanism and the flip cover, including: if the distance between the obstacle and the taillight is less than the first preset distance, the retractable mechanism is controlled to drive the lamp head assembly to retract to the preset retraction position or drive the lamp head assembly to remain in the preset retraction position, and the flip cover is controlled to be in the closed state.

[0012] Furthermore, it also includes: controlling the brightness of the lamp head assembly according to the position of the lamp head assembly, wherein the closer the position of the lamp head assembly is to the preset recycling position, the greater the brightness of the lamp head assembly.

[0013] Furthermore, after controlling the retractable mechanism to drive the lamp head assembly to a second preset position or to keep the lamp head assembly in the second preset position, and controlling the flip cover to open to a first preset angle, the method further includes: acquiring ambient light brightness; when the ambient light brightness is less than or equal to a preset brightness threshold, controlling the lamp head assembly to output a first light brightness; when the ambient light brightness is greater than the preset brightness threshold, controlling the lamp head assembly to output a second light brightness, wherein the second light brightness is greater than the first light brightness.

[0014] Furthermore, after controlling the retractable mechanism to drive the lamp head assembly to a first preset position or to keep the lamp head assembly at the first preset position, and controlling the flip cover to be in a closed state, the method further includes: acquiring ambient light brightness; when the ambient light brightness is less than or equal to a preset brightness threshold, controlling the lamp head assembly to output a second light brightness; when the ambient light brightness is greater than the preset brightness threshold, controlling the lamp head assembly to output a third light brightness, wherein the third light brightness is greater than the second light brightness.

[0015] Furthermore, after controlling the retractable mechanism to drive the lamp head assembly to retract to the preset retractable position or to keep the lamp head assembly in the preset retractable position, and controlling the flip cover to be in the closed state, the method further includes: controlling the lamp head assembly to output a third light brightness.

[0016] Furthermore, based on the obstacle information, controlling the shape of the lamp head assembly through the retractable mechanism and the flip cover also includes: if there are no obstacles within a preset range behind the vehicle, controlling the retractable mechanism to drive the lamp head assembly to a third preset position or to keep the lamp head assembly at the third preset position, and controlling the flip cover to open to a second preset angle, wherein the second preset angle is greater than the first preset angle, the third preset position and the second preset position are located on the same side of the preset retraction position, and the distance between the third preset position and the preset retraction position is greater than the distance between the second preset position and the preset retraction position.

[0017] Furthermore, determining whether the vehicle meets the conditions for entering the intelligent taillight collision avoidance mode based on the vehicle status information includes: when the vehicle is powered on and the ignition switch is turned on, determining that the vehicle meets the conditions for entering the intelligent taillight collision avoidance mode.

[0018] Furthermore, the control method also includes: receiving a taillight off control command input by the user through the taillight control switch; responding to the taillight off control command to control the flip cover to be in a closed state, and controlling the retractable mechanism to drive the lamp head assembly to retract to the preset retracted position or drive the lamp head assembly to remain in the preset retracted position.

[0019] To address the aforementioned problems, this invention also proposes a control device for a vehicle taillight. The taillight includes a lamp head assembly, a retractable mechanism, and a flip-up cover. The retractable mechanism drives the lamp head assembly to extend and retract. The flip-up cover covers the lamp head assembly to adjust the occlusion area of ​​the lamp head assembly when the flip-up cover is opened or closed. The control device includes: an acquisition module for acquiring vehicle status information; a judgment module for determining whether the vehicle meets the conditions for entering the intelligent taillight collision avoidance mode based on the vehicle status information; and a control module for controlling the vehicle to enter the intelligent taillight collision avoidance mode when the vehicle meets the conditions, thereby acquiring obstacle information behind the vehicle and controlling the shape of the lamp head assembly based on the obstacle information via the retractable mechanism and the flip-up cover.

[0020] According to an embodiment of the present invention, the vehicle taillight control device acquires vehicle status information and determines whether the vehicle meets the conditions for entering the intelligent taillight collision avoidance mode. When the vehicle meets the conditions for entering the intelligent taillight collision avoidance mode, the device controls the vehicle to enter the intelligent taillight collision avoidance mode. Under the intelligent taillight collision avoidance mode, the device acquires information about obstacles behind the vehicle and, based on the obstacle information, controls the shape of the lamp head assembly through a retractable mechanism and a flip cover. For example, the retractable mechanism controls the extension and retraction of the taillight, and the flip cover adjusts the occlusion area of ​​the lamp head assembly, thereby reducing the concealed area of ​​the lamp head assembly. The taillights undergo dynamic changes, resulting in a cool and dynamic transformation that enhances the vehicle's intelligence and technological feel, improving the user experience. The dynamic transformation also strengthens the warning effect to vehicles behind, thus improving driving safety. Furthermore, because the taillight structure can dynamically deform, the lamp head assembly can extend, retract, and change its hidden area under the drive of the telescopic mechanism and the flip-up cover. Therefore, in the event of a collision with a following vehicle, the retracting and hiding of the lamp head assembly can effectively avoid or reduce damage to the taillights, thereby improving taillight safety.

[0021] To address the aforementioned problems, the present invention also proposes a vehicle comprising: a vehicle taillight control device as described in the second aspect embodiment of the present invention; or, the vehicle comprising: a processor, a memory, and a vehicle taillight control program stored in the memory and executable on the processor, wherein the vehicle taillight control program, when executed by the processor, implements the vehicle taillight control method as described in the first aspect embodiment of the present invention.

[0022] According to an embodiment of the present invention, the vehicle acquires vehicle status information and determines whether the vehicle meets the conditions for entering the intelligent taillight collision avoidance mode. When the vehicle meets the conditions for entering the intelligent taillight collision avoidance mode, the vehicle is controlled to enter the intelligent taillight collision avoidance mode. Under the intelligent taillight collision avoidance mode, information about obstacles behind the vehicle is acquired, and based on the obstacle information, the shape of the lamp head assembly is controlled by a retractable mechanism and a flip cover. For example, the retractable mechanism controls the extension and retraction of the taillights, and the flip cover adjusts the occlusion area of ​​the lamp head assembly, so that the hidden area of ​​the lamp head assembly dynamically changes. The taillights undergo dynamic transformations, creating a cool and visually appealing display that enhances the vehicle's intelligence and technological sophistication, improving the user experience. This dynamic transformation also strengthens the warning effect to vehicles behind, improving driving safety. Furthermore, because the taillight structure can dynamically deform, the lamp head assembly can extend, retract, and change its concealed area under the drive of the telescopic mechanism and the flip-up cover. Therefore, in the event of a collision with a following vehicle, the retracting and concealing of the lamp head assembly can effectively avoid or reduce damage to the taillights, thus improving taillight safety.

[0023] To address the aforementioned problems, the present invention also proposes a computer-readable storage medium storing a control program for a vehicle taillight. When the vehicle taillight control program is executed by a processor, it implements the vehicle taillight control method as described in the first aspect embodiment of the present invention.

[0024] According to an embodiment of the present invention, when a computer-readable storage medium storing a vehicle taillight control program thereon is executed by a processor, it acquires vehicle status information and determines whether the vehicle meets the conditions for entering the intelligent taillight collision avoidance mode based on the vehicle status information. When the vehicle meets the conditions for entering the intelligent taillight collision avoidance mode, it controls the vehicle to enter the intelligent taillight collision avoidance mode. Under the intelligent taillight collision avoidance mode, it acquires information about obstacles behind the vehicle and, based on the obstacle information, controls the shape of the lamp head assembly through a retractable mechanism and a flip cover. For example, the retractable mechanism controls the extension and retraction of the taillight, and the flip cover adjusts the occlusion area of ​​the lamp head assembly. This design allows for dynamic changes in the hidden area of ​​the taillight assembly, resulting in a cool and dynamic taillight transformation. This enhances the vehicle's intelligence and technological feel, improving the user experience. The dynamic transformation of the taillights also strengthens the warning effect to vehicles behind, thus improving driving safety. Furthermore, because the taillight structure can dynamically deform, the taillight assembly can extend, retract, and change its hidden area under the drive of the telescopic mechanism and the flip-up cover. Therefore, in the event of a collision with a following vehicle, the retraction and concealment of the taillight assembly can effectively avoid or reduce damage to the taillights, thereby improving taillight safety.

[0047] 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.

[0048] The following is for reference. Figures 1-9A method, apparatus, vehicle, and storage medium for controlling vehicle taillights according to embodiments of the present invention are described.

[0049] First, combined Figure 1-6 The relevant structure of the vehicle taillights involved in the embodiments of the present invention is described.

[0050] in, Figure 1 and Figure 2 The diagram illustrates the structural states of the vehicle taillights in the retracted and extended states according to an embodiment of the present invention. Figure 3 and Figure 4 An embodiment of the present invention is shown for... Figure 1-2 A schematic diagram of a drive structure for the taillight structure, namely a telescopic mechanism. Figure 5 and Figure 6 Another embodiment of the invention is shown for... Figure 1-2 Another driving structure for the taillight structure is illustrated in the diagram of another telescopic mechanism. The telescopic structure for driving the taillights involved in this embodiment of the invention can employ either of the two driving structures. That is to say, for... Figure 1 and Figure 2 The taillight structure shown can be extended or retracted by a retractable mechanism. The retractable mechanism involved in this embodiment of the invention may include two structures and their corresponding driving methods, wherein... Figure 3 and Figure 4 One type of retractable mechanism and its corresponding drive method are shown. Figure 5 and Figure 6 Another scalable mechanism and its corresponding actuator are shown.

[0051] First, combined Figure 1-4 Describe the driving structure of one type of taillight, namely a retractable mechanism. Specifically, such as... Figures 1-4As shown, in one embodiment of the present invention, the taillight 100 includes a lamp head assembly 40, a telescopic mechanism (not shown in the figure), and a flip cover (i.e., an opening and closing member 60). The telescopic mechanism is used to drive the lamp head assembly 40 to extend and retract, and the flip cover is disposed on the lamp head assembly 40 to adjust the shading area of ​​the lamp head assembly 40 when the flip cover is opened or closed. Specifically, when the flip cover is closed, the area it covers of the lamp head assembly 40 is the initial coverage area, such as the coverage area when the lamp head assembly 40 is in the retracted state, at which point only a small portion of the lamp head assembly 40 is exposed. When the flip cover is opened, the coverage area of ​​the lamp head assembly 40 varies depending on the opening angle. Specifically, the larger the opening angle, the smaller the coverage area of ​​the lamp head assembly 40, meaning more of the lamp head assembly 40 is exposed and less is hidden; conversely, the smaller the opening angle, the larger the coverage area of ​​the lamp head assembly 40, meaning less of the lamp head assembly 40 is exposed and more is hidden. Therefore, by opening or closing the flip cover, the coverage area of ​​the lamp head assembly 40 can be adjusted, causing a dynamic change in the hidden area of ​​the lamp head assembly. Furthermore, as... Figure 1 As shown, the taillight 100 also includes an outer lamp housing 10. The telescopic mechanism includes a first inner lamp sleeve 20, a drive assembly 30, and a flexible connector 50.

[0052] That is to say, in this embodiment, the taillight 100 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 flexible connector 50. The first inner lamp sleeve 20 is movably disposed inside the outer lamp housing 10. The drive assembly 30 is disposed on the outer lamp housing 10 and is connected to the first inner lamp sleeve 20 in a transmission manner. The lamp head assembly 40 is movably disposed inside the first inner lamp sleeve 20. The flexible connector 50 passes through the first inner lamp sleeve 20 and is connected between the outer lamp housing 10 and 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.

[0053] 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 taillight 100.

[0054] Furthermore, the first inner lamp sleeve 20 is movably configured relative to the outer lamp housing 10. By mounting the drive assembly 30 on the outer lamp housing 10, the drive assembly 30 is connected to the first inner lamp sleeve 20. This allows the drive assembly 30 to drive the first inner lamp sleeve 20 to extend and retract relative to the outer lamp housing 10. Additionally, by movably configuring the lamp head assembly 40 relative to the first inner lamp sleeve 20, a flexible connector 50 is inserted through the first inner lamp sleeve 20, connecting the outer lamp housing 10 and the lamp head assembly 40. When the drive assembly 30 drives the first inner lamp sleeve 20 to extend and retract relative to the outer lamp housing 10, the flexible connector 50, being a non-elastic element, does not deform. The contact area between the flexible connector 50 and the first inner lamp sleeve 20 gradually moves, thereby causing 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 taillight 100, and the implementation of this multi-stage extension and retraction is simple and reliable.

[0055] In this way, the taillight 100 can have a retracted state and an extended state. When the taillight 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 taillight 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 taillight 100 according to actual needs, which can enhance the refinement and technological feel of the vehicle taillight 100 and improve the user experience.

[0056] 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 third transmission part 221, 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.

[0057] 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.

[0058] Combination Figure 2 and Figure 4 As shown, the flexible connector 50 is strip-shaped, and a through hole 23 is provided on the outer peripheral wall of the first inner lamp sleeve 20. The bottom wall of the through hole 23 is arc-shaped. The flexible connector 50 passes through the through hole 23 and contacts the bottom wall of the through hole 23. Specifically, by setting the flexible connector 50 as a strip and setting the bottom wall of the through hole 23 as arc-shaped, when the flexible connector 50 passes through the first inner lamp sleeve 20, the through hole 23 can accommodate the flexible connector 50, and the flexible connector 50 contacts the arc-shaped bottom wall of the through hole 23. Therefore, when the first inner lamp sleeve 20 moves relative to the outer lamp housing 10, the contact area between the flexible connector 50 and the bottom of the through hole 23 can be increased, making the movement of the flexible connector 50 relative to the through hole 23 more stable and smooth. Consequently, when the flexible connector 50 drives the lamp head assembly 40 to move relative to the first inner lamp sleeve 20, the stability and smoothness of the movement of the lamp head assembly 40 can be improved.

[0059] Combination Figure 1 and Figure 2 As shown, the vehicle taillight 100 may further include: an opening / closing member 60 (i.e., a flip cover), which is rotatably mounted on the lamp head assembly 40. The opening / closing member 60 is slidably engaged with the first inner lamp sleeve 20, and the top of the opening / closing member 60 covers a portion of the lamp head assembly 40, thereby changing the area of ​​the lamp head assembly 40 covered by the opening / closing member 60 when the lamp head assembly 40 extends or retracts relative to the first inner lamp sleeve 20. Specifically, the opening / closing member 60 is rotatably mounted on the lamp head assembly 40, and the top of the opening / closing member 60 can cover a portion of the lamp head 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 lamp head assembly 40, thereby changing the area of ​​the lamp head assembly 40 covered by the opening / closing member 60, realizing the concealment or exposure of the lamp head assembly 40, and further enhancing the technological and refined feel of the taillight 100.

[0060] Furthermore, combined 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.

[0061] Furthermore, combined Figure 3 and Figure 4 As shown, the slide groove 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 taillight 100 is in the retracted state, the sliding part 24 cooperates with the first groove segment 6211. When the taillight 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 slide and engage with the first groove segment 6211. 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 engage with the second groove segment 6212. The sliding part 24 drives the engaging rod 62 to rotate relative to the lamp head assembly 40, so that the opening and closing part 60 opens relative to the lamp head assembly 40. Thus, the covering area of ​​the opening and closing part 60 on the lamp head assembly 40 can be different in different states of the taillight 100, which can further enhance the exquisite and technological feel of the taillight 100.

[0062] Combination Figures 1-4As 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 taillight 100.

[0063] Combination 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 is fitted onto the lamp head 41, a flexible connector 50 is connected to the second inner lamp sleeve 42, and an opening / closing member 60 is rotatably mounted 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 to connect the flexible connector 50, and the opening / closing member 60 can be conveniently mounted on the lamp head assembly 40. This protects the structural stability of the lamp head 41, prevents the flexible connector 50 from being pulled, and prevents the opening / closing member 60 from damaging the structure of the lamp head 41, thereby further improving the structural reliability of the vehicle's taillight 100.

[0064] Combination Figure 3 and Figure 4 As shown, the taillight 100 of the vehicle may further include: an elastic reset member 70, with both ends of the elastic reset member 70 connected between the outer lamp housing 10 and the lamp head assembly 40. Specifically, by connecting both ends of the elastic reset member 70 between the outer lamp housing 10 and the lamp head assembly 40, when the taillight 100 is in the retracted state, the elastic reset member 70 can be in a natural state. During the process of the taillight 100 switching from the retracted state to the extended state, the elastic reset member 70 is gradually stretched. On the one hand, this can provide damping for the movement of the lamp head assembly 40, improving the movement stability of the lamp head assembly 40. On the other hand, the elastic reset member 70 can store elastic potential energy. When the taillight 100 switches from the extended state to the retracted state, the elastic reset member 70 releases the elastic potential energy, which can drive the lamp head assembly 40 to retract rapidly relative to the outer lamp housing 10, thereby further improving the reliability and stability of the vehicle's taillight 100.

[0065] Combination Figure 3 and Figure 4As shown, there are at least two flexible connectors 50, which are spaced apart on the outer periphery of the lamp head assembly 40. Specifically, the flexible connectors 50 can be set to at least two, so that when the first inner lamp sleeve 20 extends or retracts relative to the outer lamp housing 10, the at least two flexible connectors 50 can simultaneously exert force on the lamp head assembly 40. Since the at least two flexible connectors 50 are spaced apart on the outer periphery of the lamp head assembly 40, the force exerted by the at least two flexible connectors 50 on the lamp head assembly 40 can be evenly distributed on the outer periphery of the lamp head assembly 40, thereby improving the stability of the lamp head assembly 40 extending or retracting relative to the first inner lamp sleeve 20 and improving the reliability of the vehicle's taillight 100.

[0066] On the other hand, combining Figure 1-2 and Figure 5-6 Describe another taillight drive structure, namely another retractable mechanism. Specifically, in conjunction with... Figure 1-2 and Figure 5-6 As shown, in another embodiment of the present invention, the taillight 100 includes a lamp head assembly 40, a telescopic mechanism (not shown in the figure), and a flip cover (i.e., an opening / closing member 60). The telescopic mechanism drives the lamp head assembly 40 to extend or retract, and the flip cover covers the lamp head assembly 40 to expose or conceal the lamp head assembly 40 when it is opened or closed. Additionally, in conjunction with... Figure 1-2 and Figure 5-6 As shown, the taillight 100 also includes an outer lamp housing 10. The telescopic mechanism includes a first inner lamp sleeve 20, a drive assembly 30, and a transmission mating component 80.

[0067] That is to say, in this embodiment, the taillight 100 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 component 80. The first inner lamp sleeve 20 is movably disposed inside 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 inside the first inner lamp sleeve 20. The transmission coupling component 80 is disposed on the first inner lamp sleeve 20. One side of the transmission coupling component 80 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.

[0068] 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.

[0069] 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 80 on the first inner lamp sleeve 20, one side of the transmission fitting 80 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 80 can be in transmission engagement with the outer lamp housing 10, and the transmission fitting 80 can move relative to the outer lamp housing 10. The moving transmission fitting 80 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.

[0070] 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.

[0071] Combination Figure 5 and Figure 6 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 80 and is in transmission mating with the transmission mating member 80. The second transmission part 421 is located on the other side of the transmission mating member 80 and is in transmission mating with the transmission mating member 80. 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 80 can be in transmission mating with the first transmission part 11, and the other side of the transmission mating member 80 can be in transmission mating with the second transmission part 421. This makes the transmission mating between the transmission mating member 80 and the outer lamp housing 10, as well as the transmission mating between the transmission mating member 80 and the lamp head assembly 40, more stable and reliable. This makes the transmission of power between the transmission mating member 80, 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.

[0072] Furthermore, combined Figure 5 and Figure 6As shown, the transmission mating part 80 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 80 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 80 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.

[0073] Combination Figure 5 and Figure 6 As 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.

[0074] Combination Figure 5 and Figure 6As shown, there are at least two transmission coupling components 80, which are spaced apart on the circumferential sidewall of the first inner lamp sleeve 20. Specifically, by setting at least two transmission coupling components 80, at least two transmission coupling components 80 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 80 can be distributed more evenly, 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.

[0075] Combination Figure 5 and Figure 6 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.

[0076] Furthermore, combined Figure 5 and Figure 6 As 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.

[0077] Combination Figure 1-2 and Figure 5-6As 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.

[0078] Combination Figure 5 and Figure 6 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.

[0079] Furthermore, combined Figure 5 and Figure 6As 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.

[0080] 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.

[0081] Furthermore, combined Figure 5 and Figure 6 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 is fitted onto the lamp head 41, a second transmission part 421 is disposed on the second inner lamp sleeve 42, and an opening / closing member 60 is 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 engagement member 80, 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.

[0082] Based on the above description of the structure of the taillight 100 and any one of the drive structures (i.e., telescopic mechanisms) used to drive the two types of taillights, the following combines... Figure 7-9 This invention describes a method for controlling a vehicle taillight, a control device, a vehicle, and a storage medium, wherein the vehicle taillight is, for example, the taillight 100 described in the above embodiments.

[0083] Figure 7 This is a flowchart of a vehicle taillight control method according to an embodiment of the present invention. As mentioned above, the vehicle taillight includes a lamp head assembly, a telescopic mechanism, and a flip-up cover. The telescopic mechanism drives the lamp head assembly to extend and retract, and the flip-up cover covers the lamp head assembly to adjust the area of ​​obstruction to the lamp head assembly when the flip-up cover is opened or closed. As mentioned above, the opening and closing process of the flip-up cover is linked to the action of the telescopic mechanism. That is, when the telescopic mechanism operates in different positions, the state of the flip-up cover can be adjusted accordingly, driving the flip-up cover to close or controlling its opening angle. Further details are omitted here. In other words, the extension and retraction of the telescopic mechanism and the flip-up action of the cover are linked. The opening and closing of the flip-up cover can be achieved by relying on the linkage of the two, thus eliminating the need for separate control of the flip-up cover and saving the cost of separate control. Based on this, as... Figure 7 As shown, a method for controlling vehicle taillights according to an embodiment of the present invention specifically includes the following steps:

[0084] Step S1: Obtain vehicle status information.

[0085] In a specific example, vehicle status information includes, but is not limited to, overall vehicle operating status information, operating status information of various vehicle components, vehicle gear information, and status information of various vehicle switches. Specifically, vehicle status information can be obtained through one or more of the vehicle's instrument panel, multiple sensing units on the vehicle, and multiple control units on the vehicle.

[0086] Step S2: Determine whether the vehicle meets the conditions for entering the taillight intelligent collision avoidance mode based on the vehicle status information.

[0087] Specifically, based on the vehicle status information obtained in step S1, it is determined whether the vehicle meets the conditions for entering the taillight intelligent collision avoidance mode. If the vehicle meets the conditions for entering the taillight intelligent collision avoidance mode, the vehicle is controlled to enter the corresponding taillight intelligent collision avoidance mode. Otherwise, if the vehicle does not meet the conditions for entering the taillight intelligent collision avoidance mode, the vehicle is controlled not to enter the taillight intelligent collision avoidance mode.

[0088] Step S3: If yes, control the vehicle to enter the taillight intelligent collision avoidance mode to obtain obstacle information behind the vehicle, and based on the obtained obstacle information, control the shape of the lamp head assembly through the retractable mechanism and the flip cover.

[0089] Specifically, when the vehicle's status information determines that it meets the conditions for entering the intelligent taillight collision avoidance mode, the system controls the vehicle to enter the corresponding intelligent taillight collision avoidance mode. In this mode, obstacle information is first acquired. This is achieved through an obstacle detection device located at the rear of the vehicle to detect the presence of obstacles within a certain range behind the vehicle. If an obstacle is found, further obstacle information is acquired, such as the distance between the obstacle and the rear of the vehicle. Obstacles behind the vehicle include, for example, other vehicles, pedestrians, or other objects. The obstacle detection device can be, for example, radar or a camera. After detecting and acquiring obstacle information, the system controls the shape of the lamp head assembly using a retractable mechanism and a flip-up cover. For example, the retractable mechanism can extend or retract the lamp head assembly, changing its structural shape; the flip-up cover can be opened or closed to adjust the area obscured by the lamp head assembly, thus adjusting the exposed and hidden areas of the lamp head assembly and changing its display appearance. Meanwhile, the dynamic deformation of the taillights can enhance the warning effect to vehicles behind, thereby improving driving safety; and in the event of a collision with a vehicle behind, the taillights can be effectively protected from or have their damage reduced by retracting and hiding the lamp head assembly (such as increasing the hiding area of ​​the lamp head assembly), thereby improving the safety of the taillights.

[0090] Specifically, the specific structure and working principle of the telescopic mechanism and the flip cover, as well as the specific implementation process of controlling the telescopic mechanism to drive the lamp head assembly to extend and retract, and controlling the flip cover to adjust the shading area of ​​the lamp head assembly, can be found in the previous text and will not be repeated here.

[0091] Therefore, the vehicle taillight control method according to the embodiment of the present invention acquires vehicle status information, determines whether the vehicle meets the conditions for entering the intelligent taillight collision avoidance mode based on the vehicle status information, and controls the vehicle to enter the intelligent taillight collision avoidance mode when the vehicle meets the conditions for entering the intelligent taillight collision avoidance mode. Under the intelligent taillight collision avoidance mode, the method acquires information about obstacles behind the vehicle, and controls the shape of the lamp head assembly based on the obstacle information through a retractable mechanism and a flip cover. For example, the retractable mechanism controls the extension and retraction of the taillight, and the flip cover adjusts the shading area of ​​the lamp head assembly, thereby reducing the hidden surface of the lamp head assembly. The dynamic changes generated by the taillights allow them to transform in a cool and dynamic way, enhancing the vehicle's intelligence and technological feel, and improving the user experience. The dynamic transformation of the taillights also strengthens the warning effect to vehicles behind, thus improving driving safety. Furthermore, because the taillight structure can dynamically deform, the lamp head assembly can extend and retract and change its hidden area under the drive of the telescopic mechanism and the flip-up cover. Therefore, in the event of a collision with a vehicle behind, the lamp head assembly can be retracted and hidden to effectively avoid or reduce damage to the taillights, thereby improving taillight safety.

[0092] In one embodiment of the present invention, step S3, based on obstacle information, controls the shape of the lamp head assembly through a retractable mechanism and a flip cover, including: determining whether there is an obstacle within a preset range (such as 5 meters, 10 meters or other distances) behind the vehicle; if so, obtaining the distance between the obstacle and the taillight; and controlling the shape of the lamp head assembly through a retractable mechanism and a flip cover based on the distance between the obstacle and the taillight.

[0093] In a specific embodiment, obstacle information includes, for example, whether there are obstacles within a certain range behind the vehicle. That is, by detecting whether there are obstacles within a preset range behind the vehicle, if an obstacle is present, it is considered a safety hazard to the vehicle. Then, the distance between the obstacle and the taillight is further obtained, and based on different distances, the retractable mechanism and the flip-up cover are used to control the taillight assembly to form different shapes. If there are no obstacles within the preset range behind the vehicle, it is considered not a safety hazard to the vehicle. Then, according to a set control strategy, the retractable mechanism and the flip-up cover are controlled to form the taillight assembly into a predetermined shape.

[0094] In one embodiment of the present invention, the shape of the lamp head assembly is controlled by a retractable mechanism and a flip cover based on the distance between the obstacle and the taillight. This includes: if there is an obstacle within a preset range behind the vehicle, and the distance between the obstacle and the taillight is greater than or equal to a first preset distance and less than or equal to a second preset distance, then the retractable mechanism is controlled to drive the lamp head assembly to a first preset position or to drive the lamp head assembly to remain at the first preset position, and the flip cover is controlled to be in a closed state to cover or hide most of the area of ​​the lamp head assembly, exposing only a small part of the front section of the lamp head assembly, i.e., the initial exposed part when in the retracted state.

[0095] In a specific embodiment, the first preset distance and the second preset distance are pre-set distance values ​​that can be set according to actual needs. They are set based on the distance between obstacles behind the vehicle and the taillights. Specifically, when the distance between the obstacle behind the vehicle and the taillights is less than the first preset distance (e.g., but not limited to 2 meters), it is considered that the distance between the obstacle and the taillights is very close, making a collision highly likely and posing a high risk. In this case, the shape of the taillight assembly can be controlled to ensure taillight safety, such as controlling the taillight assembly to retract and be mostly hidden. When the distance between the obstacle behind the vehicle and the taillights is greater than or equal to the first preset distance (e.g., but not limited to 2 meters) and less than or equal to the second preset distance (e.g., but not limited to 5 meters), i.e., the distance is between the first and second preset distances, it is considered that the distance between the obstacle and the taillights is moderate. If the driver is not careful, a collision may occur, posing a moderate risk. In this case, the shape of the taillight assembly can be controlled to ensure taillight safety while also maintaining a small portion of the taillight's display function, such as controlling the taillight assembly to extend only a small portion and be mostly hidden. If the distance between an obstacle behind the vehicle and the taillights is greater than a second preset distance (such as, but not limited to, 5 meters), it is considered that the distance between the obstacle and the vehicle's taillights is relatively far, and a collision is unlikely to occur during normal driving, and the degree of danger is low. Therefore, the shape of the taillight assembly can be controlled based on ensuring the safety of the taillights while taking into account most of the display functions of the taillights. For example, the taillight assembly can be controlled to extend most of its length and partially conceal its length.

[0096] Furthermore, when the distance between the obstacle behind the vehicle and the taillight is between the first preset distance and the second preset distance, it is considered that the distance between the obstacle and the vehicle's taillight is moderate. If the driver is not careful, a collision may occur, and the degree of danger is moderate. In order to balance the safety of the taillight and the display of some dynamic deformation effects, the taillight can be driven to the first position. The first position is used to indicate that the taillight is driven to the first preset position to realize the extension and retraction of the taillight. At the same time, the flip cover is controlled to be in the closed state, so that the flip cover covers most of the area of ​​the lamp head assembly, only revealing a small part of the front part of the lamp head assembly, thus achieving the concealment of most of the taillight. This ensures the safety and stability of the taillight during driving, while also displaying some dynamic deformation effects of the taillight, enhancing the warning effect to following vehicles. In addition, in the first position, the taillight extends a short distance, which can be retracted in time when a collision is judged to be imminent, improving the safety and reliability of the taillight. Specifically, when the distance between the obstacle and the taillight is between a first preset distance and a second preset distance, the taillight assembly is controlled to move to the first position. This includes: if the taillight assembly is not in the first preset position at this time, the retractable mechanism can be controlled to extend or retract the taillight assembly to the first preset position; if the taillight assembly is already in the first preset position at this time, the retractable mechanism can be controlled to keep the taillight assembly in the first preset position. At the same time, the flip cover is controlled to be in the closed state, so that the flip cover covers most of the area of ​​the taillight assembly, only revealing a small part of the front part of the taillight assembly, thus achieving most of the taillight concealment.

[0097] In a specific example, the first preset distance is set to 2 meters, and the second preset distance is set to 5 meters. That is, when 2 meters ≤ the distance between the obstacle and the taillight is ≤ 5 meters, the distance between the obstacle and the vehicle taillight is considered to be moderate, and the degree of danger is moderate. In order to balance the safety of the taillight and the display of some dynamic deformation effects, the taillight can be driven to the first position. The first position is used to indicate that the taillight is driven to the first preset position to realize the extension and retraction of the taillight. At the same time, the flip cover is controlled to be in the closed state, so that the flip cover covers most of the area of ​​the lamp head assembly, only revealing a small part of the front part of the lamp head assembly, realizing the concealment of most of the taillight, so as to ensure the safety and stability of the taillight during driving. At the same time, it can display some dynamic deformation effects of the taillight, enhancing the warning effect to the following vehicles. In addition, in the first position, the taillight extends a short distance, which can retract the taillight in time when a collision is judged to be imminent, improving the safety and reliability of the taillight. Specifically, when the distance between the obstacle (≤2 meters) and the taillight (≤5 meters), the taillight assembly is controlled to operate in the first position. This includes: if the taillight assembly is not in the first preset position, the retractable mechanism can be controlled to extend or retract the taillight assembly to the first preset position; if the taillight assembly is already in the first preset position, the retractable mechanism is controlled to keep the taillight assembly in the first preset position. Simultaneously, the flip cover is controlled to be closed, so that the flip cover covers most of the taillight assembly area, revealing only a small portion of the front of the taillight assembly, thus achieving partial concealment of the taillight.

[0098] In one embodiment of the present invention, the shape of the lamp head assembly is controlled by a retractable mechanism and a flip cover based on the distance between the obstacle and the taillight. The method includes: if there is an obstacle within a preset range behind the vehicle and the distance between the obstacle and the taillight is greater than a second preset distance, the retractable mechanism is controlled to drive the lamp head assembly to a second preset position or to keep the lamp head assembly at the second preset position, and the flip cover is controlled to open to a first preset angle to cover or hide a small part of the lamp head assembly, thereby exposing more of the lamp head assembly. The second preset position and the first preset position are located on the same side of the preset retraction position, and the distance between the second preset position and the preset retraction position is greater than the distance between the first preset position and the preset retraction position.

[0099] Specifically, when the distance between an obstacle behind the vehicle and the taillights is greater than a second preset distance (e.g., but not limited to 5 meters), it is considered that the distance between the obstacle and the taillights is relatively far, and a collision is unlikely during normal driving, resulting in a low level of danger. Therefore, the shape of the taillight assembly can be controlled to ensure taillight safety while maintaining most of its display function. This could involve controlling the taillight assembly to extend most of its surface and partially conceal it. To balance taillight safety and the dynamic deformation effect of the display portion, the taillights can be driven to a second position. This second position indicates that the taillights should be driven to a second preset position, enabling the taillights to extend and retract. Simultaneously, the flip cover can be opened, for example, to a first preset angle (e.g., 7 degrees). This allows the flip cover to cover a small portion of the taillight assembly, revealing most of it, thus partially concealing the taillights. This ensures the safety and stability of the taillights during driving while maintaining a certain dynamic display effect. Understandably, when the distance between the obstacle and the taillights is greater than the second preset distance, driving safety is relatively high, and collisions are less likely. Therefore, driving the taillights to the second position at this time, extending them further, showcases the dynamic deformation effect of the taillights more, and enhances the warning effect to following vehicles. Simultaneously, it allows for timely retraction of the taillights when a collision is anticipated, balancing the safety and reliability of the taillights. Specifically, when the distance between the obstacle and the taillights is greater than the second preset distance, the lamp head assembly is controlled to operate to the second position. This includes: if the lamp head assembly is not in the second preset position, the retractable mechanism can be controlled to extend or retract the lamp head assembly to the second preset position; if the lamp head assembly is already in the second preset position, the retractable mechanism is controlled to keep the lamp head assembly in the second preset position. Simultaneously, the flip cover is controlled to open to the first preset angle to cover a small area of ​​the lamp head assembly, partially concealing it to ensure the safety and stability of the taillights during driving, while maintaining a certain dynamic display effect. The second preset position and the first preset position are located on the same side of the preset retraction position, and the distance between the second preset position and the preset retraction position is greater than the distance between the first preset position and the preset retraction position. In other words, the second preset position is farther from the preset retraction position than the first preset position. That is, in the second gear, the taillight extends further from the preset retraction position than in the first gear, and the opening angle of the flip cover is larger.

[0100] In a specific example, the second preset distance is set to 5 meters. That is, when the distance between the obstacle and the taillight is greater than 5 meters, it is considered that the distance between the obstacle and the vehicle taillight is relatively far and the danger level is low. In order to balance the safety of the taillight and the display of most of the dynamic deformation effect, the taillight can be driven to the second position, and at the same time, the flip cover is controlled to open at the first preset angle, such as 7 degrees, so that the flip cover covers a small part of the lamp head assembly, realizing a small part of the taillight hiding, to ensure the safety and stability of the taillight during driving, while also ensuring that the taillight maintains a certain dynamic display effect, and also enhancing the warning effect to the following vehicles. Specifically, when the distance between the obstacle and the taillight is greater than 5 meters, the taillight assembly is controlled to move to the second position. This includes: if the taillight assembly is not in the second preset position at this time, the telescopic mechanism can be controlled to drive the taillight assembly to extend or retract to the second preset position; if the taillight assembly is already in the second preset position at this time, the telescopic mechanism is controlled to drive the taillight assembly to remain in the second preset position, and at the same time, the flip cover is controlled to open 7 degrees to cover a small part of the taillight assembly, so that the taillight assembly is partially hidden.

[0101] In one embodiment of the present invention, the shape of the lamp head assembly is controlled by a retractable mechanism and a flip cover based on the distance between the obstacle and the taillight. The method includes: if there is an obstacle within a preset range behind the vehicle and the distance between the obstacle and the taillight is less than a first preset distance, the retractable mechanism is controlled to drive the lamp head assembly to retract to a preset retracted position or to keep the lamp head assembly in the preset retracted position, and the flip cover is controlled to be in a closed state so as to cover or hide most of the area of ​​the lamp head assembly and only expose a small part of the front part of the lamp head assembly.

[0102] Specifically, when the distance between an obstacle behind the vehicle and the taillights is less than a first preset distance (e.g., but not limited to 2 meters), it is considered that the distance between the obstacle and the taillights is very close, making a collision highly likely and posing a high risk. Therefore, the shape of the taillight assembly can be controlled to ensure taillight safety, such as controlling the retraction of the taillight assembly and concealing most of it. To ensure taillight safety and avoid or reduce damage caused by collisions, the taillights can be turned off and retracted to a preset retraction position, which is the position corresponding to the retracted taillight assembly or the limit of its retraction. At this time, the taillights are in the retracted state, and the flip-up cover is closed to cover or conceal most of the taillight assembly, exposing only a small portion of the front of the assembly. This avoids or reduces damage caused by collisions, thereby improving the safety and stability of the taillights during driving. Specifically, when the distance between the obstacle and the taillight is less than a first preset distance, if the taillight assembly is not in the preset retractable position, the retractable mechanism can be controlled to drive the taillight assembly to retract to the preset retractable position. If the taillight assembly is already in the preset retractable position, the retractable mechanism can be controlled to drive the taillight assembly to remain in the preset retractable position. At the same time, the flip cover is controlled to be in the closed state to cover or hide most of the area of ​​the taillight assembly, only exposing a small part of the front section of the taillight assembly.

[0103] In a specific example, the first preset distance is set to 2 meters. That is, when the distance between the obstacle and the taillight is less than 2 meters, it is considered that the distance between the obstacle and the vehicle taillight is very close and a collision is very likely to occur, which is highly dangerous. In order to ensure the safety of the taillight and avoid or reduce the damage to the taillight caused by the collision, the taillight can be turned off and retracted to the preset retraction position. At the same time, the flip cover is controlled to be in the closed state to cover or hide most of the area of ​​the lamp head assembly, only exposing a small part of the front part of the lamp head assembly, thereby avoiding or reducing the damage to the taillight caused by the collision and improving the safety and stability of the taillight during driving. Specifically, when the distance between the obstacle and the taillight is less than 2 meters, the taillight assembly is retracted to a preset retractable position. This includes: if the taillight assembly is not in the preset retractable position, the telescopic mechanism can be controlled to retract the taillight assembly to the preset retractable position; if the taillight assembly is already in the preset retractable position, the telescopic mechanism is controlled to keep the taillight assembly in the preset retractable position, while the flip cover is controlled to be closed to cover or hide most of the taillight assembly, exposing only a small part of the front of the taillight assembly.

[0104] In a specific embodiment, when the taillight is in the retracted state, specifically at a preset retracted position, the taillight has retracted to its limit position and cannot retract further. The taillight can extend from the preset retracted position along a set extension direction, reaching its maximum extension position, at which point it cannot extend further, and can retract along a retraction direction opposite to the extension direction, reaching the preset retracted position, at which point it cannot retract further. The preset retracted position and the maximum extension position form the maximum extension stroke or maximum retraction stroke of the taillight. In a specific example, when the taillight is extended to the first position, it corresponds to a first preset position, which is one-third of the maximum extension stroke of the taillight. At this time, the flip cover is in the closed state, obscuring or hiding most of the lamp head assembly area, only exposing a small portion of the front section of the lamp head assembly. When the taillight is extended to the second position, it corresponds to the second preset position, which is two-thirds of the maximum extension stroke of the taillight. At this time, the flip cover is partially open, such as opening it 7 degrees, thus partially obscuring the lamp head assembly, allowing the taillight to be partially hidden and revealing most of the lamp head assembly. When the taillight is extended to the third position, it corresponds to the third preset position, which is the maximum extension position of the taillight. At this time, the flip cover is fully open, such as opening it 12.5 degrees. At this time, the flip cover no longer obscures the lamp head assembly, allowing the lamp head assembly to be revealed to the maximum extent.

[0105] In one embodiment of the present invention, the method for controlling the vehicle taillight further includes: controlling the brightness of the lamp head assembly according to its position, wherein the closer the lamp head assembly is to the preset retraction position, the greater the brightness of the lamp head assembly. This allows the taillight brightness to be adjusted according to the degree of taillight deformation; during taillight retraction, the closer to the preset retraction position, the smaller the taillight deformation, and the farther away from the preset retraction position, the greater the taillight deformation. Since the smaller the taillight deformation, the larger the area obscured by the flip cover on the lamp head assembly, and the smaller the exposed portion of the lamp head assembly, the greater the brightness is controlled when the taillight deformation is smaller. This avoids the flip cover obscuring the light from the lamp head assembly and provides a better warning effect by increasing the brightness. Conversely, when the taillight deformation is greater, the smaller the area obscured by the flip cover on the lamp head assembly, and the more of the lamp head assembly is exposed. Therefore, the lower the brightness is controlled when the taillight deformation is greater, thus saving energy while maintaining a warning effect.

[0106] Specifically, in one embodiment of the present invention, controlling the brightness of the lamp head assembly according to its position includes: after controlling the retractable mechanism to drive the lamp head assembly to a second preset position or to keep the lamp head assembly at the second preset position, and controlling the flip cover to open to a first preset angle, acquiring the ambient light brightness; when the ambient light brightness is less than or equal to a preset brightness threshold, controlling the lamp head assembly to output a first light brightness; when the ambient light brightness is greater than the preset brightness threshold, controlling the lamp head assembly to output a second light brightness, wherein the second light brightness is greater than the first light brightness.

[0107] In a specific embodiment, the first light brightness and the second light brightness are preset brightness values, which can be set according to actual needs. The setting is based on the brightness level of the indicator light head assembly. When the first light brightness is output, the brightness of the indicator light head assembly is considered low. When the second light brightness is output, the brightness of the indicator light head assembly is considered moderate.

[0108] Specifically, when the taillights are controlled to operate in the second position, the telescopic mechanism drives the lamp head assembly to a second preset position or keeps the lamp head assembly in the second preset position. After the flip cover is opened to a first preset angle, the taillights deform significantly. At this point, the ambient light intensity is further measured to determine whether it is daytime, nighttime, or a dimly lit location. When the ambient light intensity is less than or equal to a preset brightness threshold, it is considered to be nighttime or a dimly lit location. The lamp head assembly then outputs a lower first light intensity, thus saving energy while better showcasing the dynamic deformation and welcoming effect of the taillights. When the ambient light intensity is greater than the preset brightness threshold, it is considered to be daytime. The lamp head assembly then outputs a moderate second light intensity, further enhancing the display of the taillights' dynamic deformation and welcoming effect, while also increasing the warning effect to following vehicles.

[0109] In one embodiment of the present invention, controlling the brightness of the lamp head assembly according to its position specifically includes: after controlling the retractable mechanism to drive the lamp head assembly to a first preset position or to drive the lamp head assembly to remain at the first preset position, and controlling the flip cover to be in a closed state, acquiring the ambient light brightness; when the ambient light brightness is less than or equal to a preset brightness threshold, controlling the lamp head assembly to output a second light brightness; when the ambient light brightness is greater than the preset brightness threshold, controlling the lamp head assembly to output a third light brightness, wherein the third light brightness is greater than the second light brightness.

[0110] In a specific embodiment, the second light brightness and the third light brightness are preset brightness values, which can be set according to actual needs. The setting is based on the brightness of the indicator light head assembly. When the second light brightness is output, the brightness of the light head assembly is considered to be moderate. When the third light brightness is output, the brightness of the light head assembly is considered to be high and more eye-catching.

[0111] Specifically, when the taillights are controlled to operate in position 1, the telescopic mechanism drives the lamp head assembly to a first preset position or keeps the lamp head assembly in the first preset position, and the flip cover is controlled to be in the closed state. At this time, the taillight deformation is small, so the ambient light brightness is further acquired to determine whether it is daytime, nighttime, or a dimly lit place. When the ambient light brightness is less than or equal to a preset brightness threshold, it is considered that it is nighttime or a dimly lit place, and the lamp head assembly is controlled to output a moderate second light brightness, thereby saving energy while better displaying the dynamic deformation and welcoming effect of the taillights. When the ambient light brightness is greater than the preset brightness threshold, it is considered that it is daytime, and the lamp head assembly is controlled to output a brighter and more conspicuous third light brightness, which is also better for displaying the dynamic deformation and welcoming effect of the taillights, while enhancing the warning effect to following vehicles.

[0112] In one embodiment of the present invention, the brightness of the lamp head assembly is controlled according to the position of the lamp head assembly, specifically including: after controlling the retractable mechanism to drive the lamp head assembly to retract to a preset retractable position or to drive the lamp head assembly to remain in the preset retractable position, and controlling the flip cover to be in the closed state, the lamp head assembly is controlled to output a third light brightness.

[0113] Specifically, when the taillights are retracted and turned off, the telescopic mechanism drives the lamp head assembly to a preset retraction position or keeps the lamp head assembly in a preset retraction position, and controls the flip cover to be closed. At this time, the taillights are in the retracted state and the taillights do not deform. Therefore, regardless of whether it is daytime, nighttime, or a dimly lit place, the lamp head assembly is controlled to output a brighter and more conspicuous third light, which is conducive to better displaying the dynamic deformation and welcoming effect of the taillights. At the same time, it greatly enhances the warning effect to following vehicles and improves the safety of the taillights.

[0114] In a specific embodiment, the brightness of the first light is less than that of the second light, and the brightness of the second light is less than that of the third light. Further, the brightness of the third light is less than that of the fourth light, wherein the brightness of the fourth light is used to indicate the maximum brightness of the taillights when the vehicle is braking, i.e., the maximum brake light brightness.

[0115] In one embodiment of the present invention, in step S3, based on obstacle information, the shape of the lamp head assembly is controlled by a retractable mechanism and a flip cover, including: if there is no obstacle within a preset range behind the vehicle, the retractable mechanism is controlled to drive the lamp head assembly to a third preset position or to keep the lamp head assembly at the third preset position, and the flip cover is controlled to open to a second preset angle, wherein the second preset angle is greater than the first preset angle, the third preset position and the second preset position are located on the same side of the preset retraction position, and the distance between the third preset position and the preset retraction position is greater than the distance between the second preset position and the preset retraction position.

[0116] Specifically, when there are no obstacles within a certain range behind the vehicle, it is assumed that there is no possibility of a collision with the vehicle behind, the vehicle is driving normally, and the taillights pose no safety hazard, resulting in a high level of safety. Therefore, the shape of the taillight assembly can be controlled based on maximizing the dynamic deformation display effect of the taillights, such as controlling the taillight assembly to fully extend and be fully exposed. Specifically, to fully showcase the dynamic deformation display effect of the taillights, when there are no obstacles behind the vehicle, the taillights can be driven to the third position. The third position indicates that the taillights will be driven to the third preset position, corresponding to the maximum extension position of the taillights. At this time, the flip cover is fully open, such as 12.5 degrees, thus no longer obstructing the taillight assembly and maximizing the exposure of the taillights, thereby fully showcasing the dynamic deformation display effect of the taillights and enhancing the overall technological and intelligent feel of the vehicle. Specifically, when no obstacles are detected within a certain range behind the vehicle, the taillight assembly is controlled to move to the third position. This includes: if the taillight assembly is not in the third preset position, the retractable mechanism can be controlled to extend the taillight assembly to the third preset position; if the taillight assembly is already in the third preset position, the retractable mechanism can be controlled to keep the taillight assembly in the third preset position. At the same time, the flip cover is controlled to open to the maximum opening angle, such as 12.5 degrees, so as not to obstruct the taillight assembly and to expose the taillight assembly to the maximum extent, so as to fully display the dynamic deformation display effect of the taillights and enhance the overall sense of technology and intelligence of the vehicle.

[0117] In one embodiment of the present invention, step S2, determining whether the vehicle meets the conditions for entering the intelligent taillight collision avoidance mode based on the vehicle status information, includes: when the vehicle is powered on and the ignition switch is turned on, determining that the vehicle meets the conditions for entering the intelligent taillight collision avoidance mode.

[0118] Specifically, once the vehicle is unlocked and powered on, and the ignition switch is triggered (i.e., the vehicle is ignited), the vehicle is in a driving-ready state and can respond to the accelerator pedal to enter driving mode. This determines that the vehicle meets the conditions for entering the intelligent taillight collision avoidance mode. Based on this, the vehicle can be controlled to enter the intelligent taillight collision avoidance mode. Then, based on obstacle information, the retractable mechanism and flip-up cover control the taillight assembly to change different shapes, achieving various dynamic displays. This enhances the vehicle's intelligence and technological feel, improving the user experience. Simultaneously, the dynamic deformation of the taillights strengthens the warning effect to vehicles behind, thereby improving driving safety.

[0119] In one embodiment of the present invention, the method for controlling vehicle taillights further includes: receiving a taillight off control command input by a user through a taillight control switch; responding to the taillight off control command to control the flip cover to be in a closed state, and controlling the retractable mechanism to drive the lamp head assembly to retract to a preset retracted position or to drive the lamp head assembly to remain in a preset retracted position.

[0120] Specifically, the vehicle is equipped with a taillight control switch for manual operation. Users can control the taillights manually by operating this switch. The taillight control switch can be a physical switch or button located inside the vehicle, or a virtual switch or button on a user terminal linked to the vehicle, such as a mobile phone. The in-vehicle taillight control switch can be located on the center console for convenient operation. Specifically, users can decide whether to manually turn off the taillights based on actual conditions to ensure taillight safety. For example, if a user believes there is a safety hazard and it is not suitable to activate the intelligent taillight control, the user can input a taillight-off command through the taillight control switch. The taillight controller responds to the command by closing the flip-up cover and, if the taillights are not in the preset retractable position, controlling the retractable mechanism to retract the lamp head assembly to the preset retractable position. Alternatively, if the taillights are already in the preset retractable position, the controller will keep the lamp head assembly in the preset retractable position, thus forcibly turning off the intelligent taillight control and retracting the taillights to the preset retractable position, thereby ensuring taillight safety.

[0121] In one embodiment of the present invention, the control method for the vehicle taillights further includes displaying the real-time status of the taillights. For example, the real-time status of the taillights can be displayed through a display module, such as a vehicle dashboard or a HUT (Head Unit, terminal information display unit), including whether the taillights are currently in a preset retractable position, in position 1 (in a first preset position with the flip cover closed), position 2 (in a second preset position with the flip cover partially open), or position 3 (in a third preset position with the flip cover fully open), as well as the current brightness of the taillights, so that the user can promptly know the real-time status of the taillights. Furthermore, when a taillight malfunctions, the real-time display status of the taillights can also provide a basis for fault repair, facilitating timely and accurate repair by maintenance personnel. In specific embodiments, the real-time status of the taillights can be displayed in the form of, but not limited to, images, text, videos, or three-dimensional simulation images.

[0122] To facilitate a better understanding of the present invention, the following is combined with... Figure 8 The method for controlling vehicle taillights according to specific embodiments of the present invention will be described in detail below.

[0123] In this embodiment, the control execution body of the vehicle taillight control method is, for example, the vehicle taillight controller, that is, the taillight controller controls the telescopic mechanism and the flip cover action, thereby realizing the control of the shape of the lamp head assembly.

[0124] Specifically, such as Figure 8 As shown, the method for controlling the vehicle's taillights includes the following steps:

[0125] Step S10: Process begins.

[0126] Step S11: When the vehicle is driving normally, the taillights are in position 3, that is, extended to the third preset position. The cover is flipped open to fully open (12.5 degrees) to expose the taillights to the maximum extent, and then step S12 is reversed.

[0127] Step S12: Detect whether there is an obstacle approaching from behind the vehicle. If so, proceed to step S14; otherwise, proceed to step S13.

[0128] Step S13: If no obstacle is detected behind the vehicle, the taillights remain stationary, i.e., they remain in their current position and state.

[0129] Step S14: An obstacle is detected behind the vehicle. Obtain obstacle information. Based on the obstacle information, control the taillight to deform to form different shapes. Specifically, execute step S15, step S17 or step S19.

[0130] Step S15: When the distance between the obstacle and the taillight is greater than the second preset distance, such as 5 meters, control the taillight to operate in the second position. At this time, the taillight is in the second preset position. Flip the cover to open the first preset angle, such as 7 degrees, to partially cover the taillight, thus partially hiding the taillight and revealing most of the headlight assembly. Then, proceed to step S16.

[0131] Step S16: Obtain the ambient light signal, and when it is daytime, control the taillight to output a moderate brightness level 2; when it is nighttime or a dimly lit place, control the taillight to output a lower brightness level 1.

[0132] Step S17: When the distance between the obstacle and the taillight is greater than or equal to the first preset distance (e.g., 2 meters) and less than or equal to the second preset distance (e.g., 5 meters), control the taillight to operate in the first position. At this time, the taillight is in the first preset position, the flip cover is in the closed state, covering most of the taillight area, thus hiding most of the taillight and only exposing a small part of the front part of the lamp assembly. Then, proceed to step S18.

[0133] Step S18: Obtain the ambient light signal, and when it is daytime, control the taillight to output a higher brightness level (Level 3); when it is nighttime or a dimly lit place, control the taillight to output a moderate brightness level (Level 2).

[0134] Step S19: When the distance between the obstacle and the taillight is less than the first preset distance (e.g., 2 meters), control the taillight to retract to the preset retracted position. At this time, the taillight is in the retracted state, the flip cover is in the closed state, covering most of the taillight area, thus hiding most of the taillight and only exposing a small part of the front part of the lamp assembly. Then, proceed to step S20.

[0135] Step S20: Obtain the ambient light signal, and when it is daytime, control the taillight to output a higher brightness level 3; when it is nighttime or a dimly lit place, control the taillight to output a higher brightness level 3.

[0136] Therefore, in this embodiment, the taillights can be dynamically deformed based on vehicle status information and obstacle information behind the vehicle. For example, the taillights can be extended or retracted via a telescopic mechanism, and the area obstructed by the lamp head assembly can be adjusted by flipping the cover, causing a dynamic change in the hidden area of ​​the lamp head assembly. This results in a cool transformation of the taillights, enhancing the vehicle's intelligence and technological feel, and improving the user experience. Simultaneously, the dynamic deformation of the taillights strengthens the warning effect to vehicles behind, thereby improving driving safety. Furthermore, because the taillight structure is dynamically deformable, the lamp head assembly can extend, retract, and change its hidden area under the drive of the telescopic mechanism and the flipping cover. Therefore, in the event of a collision with a following vehicle, the damage to the taillights can be effectively avoided or reduced by retracting and hiding the lamp head assembly, thus improving taillight safety.

[0137] According to an embodiment of the present invention, a vehicle taillight control method acquires vehicle status information and determines whether the vehicle meets the conditions for entering the intelligent taillight collision avoidance mode. When the vehicle meets the conditions for entering the intelligent taillight collision avoidance mode, the method controls the vehicle to enter the intelligent taillight collision avoidance mode. Under the intelligent taillight collision avoidance mode, the method acquires information about obstacles behind the vehicle and, based on the obstacle information, controls the shape of the lamp head assembly through a retractable mechanism and a flip cover. For example, the retractable mechanism controls the extension and retraction of the taillight, and the flip cover adjusts the occlusion area of ​​the lamp head assembly, thereby reducing the concealed area of ​​the lamp head assembly. The taillights undergo dynamic changes, resulting in a cool and dynamic transformation that enhances the vehicle's intelligence and technological feel, improving the user experience. The dynamic transformation also strengthens the warning effect to vehicles behind, thus improving driving safety. Furthermore, because the taillight structure can dynamically deform, the lamp head assembly can extend, retract, and change its hidden area under the drive of the telescopic mechanism and the flip-up cover. Therefore, in the event of a collision with a following vehicle, the retracting and hiding of the lamp head assembly can effectively avoid or reduce damage to the taillights, thereby improving taillight safety.

[0138] A further embodiment of the present invention discloses a control device for a vehicle taillight. As described above, the taillight includes a lamp head assembly, a telescopic mechanism, and a flip cover. The telescopic mechanism is used to drive the lamp head assembly to extend and retract, and the flip cover is disposed on the lamp head assembly to adjust the shading area of ​​the lamp head assembly when the flip cover is opened or closed.

[0139] Figure 9 This is a structural block diagram of a vehicle taillight control device according to an embodiment of the present invention, such as... Figure 9 As shown, the control device 1000 for the vehicle taillights includes: an acquisition module 1001, a judgment module 1002, and a control module 1003.

[0140] Specifically, the acquisition module 1001 is used to acquire vehicle status information.

[0157] According to an embodiment of the present invention, the vehicle taillight control device 1000 acquires vehicle status information and determines whether the vehicle meets the conditions for entering the intelligent taillight collision avoidance mode.

The dynamic changes in area allow the taillights to transform in a cool and dynamic way, enhancing the vehicle's intelligence and technological feel, and improving the user experience. The dynamic deformation of the taillights also strengthens the warning effect to vehicles behind, thus improving driving safety. Furthermore, because the taillight structure can dynamically deform, the lamp head assembly can extend, retract, and change its hidden area under the drive of the telescopic mechanism and the flip-up cover. Therefore, in the event of a collision with a following vehicle, the lamp head assembly can be retracted and hidden to effectively avoid or reduce damage to the taillights, thereby improving taillight safety.

[0161] In a specific embodiment, the vehicle can be any one of a pure electric vehicle, a gasoline vehicle, or a hybrid vehicle.

[0162] According to an embodiment of the present invention, the vehicle acquires vehicle status information and determines whether the vehicle meets the conditions for entering the intelligent taillight collision avoidance mode. When the vehicle meets the conditions for entering the intelligent taillight collision avoidance mode, the vehicle is controlled to enter the intelligent taillight collision avoidance mode. Under the intelligent taillight collision avoidance mode, information about obstacles behind the vehicle is acquired, and based on the obstacle information, the shape of the lamp head assembly is controlled by a retractable mechanism and a flip cover. For example, the retractable mechanism controls the extension and retraction of the taillights, and the flip cover adjusts the occlusion area of ​​the lamp head assembly, so that the hidden area of ​​the lamp head assembly dynamically changes. The taillights undergo dynamic transformations, creating a cool and visually appealing display that enhances the vehicle's intelligence and technological sophistication, improving the user experience. This dynamic transformation also strengthens the warning effect to vehicles behind, improving driving safety. Furthermore, because the taillight structure can dynamically deform, the lamp head assembly can extend, retract, and change its concealed area under the drive of the telescopic mechanism and the flip-up cover. Therefore, in the event of a collision with a following vehicle, the retracting and concealing of the lamp head assembly can effectively avoid or reduce damage to the taillights, thus improving taillight safety.

[0163] A further embodiment of the present invention discloses a computer-readable storage medium storing a control program for a vehicle taillight, wherein the control program for the vehicle taillight, when executed by a processor, implements the vehicle taillight control method as described in any of the above embodiments of the present invention.

[0164] According to an embodiment of the present invention, when a computer-readable storage medium storing a vehicle taillight control program thereon is executed by a processor, it acquires vehicle status information and determines whether the vehicle meets the conditions for entering the intelligent taillight collision avoidance mode based on the vehicle status information. When the vehicle meets the conditions for entering the intelligent taillight collision avoidance mode, it controls the vehicle to enter the intelligent taillight collision avoidance mode. Under the intelligent taillight collision avoidance mode, it acquires information about obstacles behind the vehicle and, based on the obstacle information, controls the shape of the lamp head assembly through a retractable mechanism and a flip cover. For example, the retractable mechanism controls the extension and retraction of the taillight, and the flip cover adjusts the occlusion area of ​​the lamp head assembly. This design allows for dynamic changes in the hidden area of ​​the taillight assembly, resulting in a cool and dynamic taillight transformation. This enhances the vehicle's intelligence and technological feel, improving the user experience. The dynamic transformation of the taillights also strengthens the warning effect to vehicles behind, thus improving driving safety. Furthermore, because the taillight structure can dynamically deform, the taillight assembly can extend, retract, and change its hidden area under the drive of the telescopic mechanism and the flip-up cover. Therefore, in the event of a collision with a following vehicle, the retraction and concealment of the taillight assembly can effectively avoid or reduce damage to the taillights, thereby improving taillight safety.
