Description

Technical Field

[0001] This application relates to the field of vehicle parts technology, and more specifically, to a concealed high-mounted brake light, a vehicle tailgate structure, and a vehicle. Background Technology

[0002] The high-mounted brake light is an auxiliary light to the vehicle's brake lights. Due to its high-mounted design, drivers of vehicles approaching from behind can still see the signal of the high-mounted brake light even if they do not see the brake lights of the vehicle in front.

[0003] High-mounted brake lights are typically installed at the upper rear of the vehicle, at the top of the rear windshield, or along the center line of the rear. Taking a high-mounted brake light installed on the rear windshield as an example, when the light is off, there will be a noticeable black area on the rear windshield, which is directly visible and affects the overall shape of the rear windshield and the vehicle, resulting in a less aesthetically pleasing appearance.

[0004] Therefore, a concealed high-mounted brake light, a vehicle tailgate structure, and a vehicle are needed to solve the above problems. Summary of the Invention

[0005] In view of this, the purpose of this application is to propose a concealed high-mounted brake light, a vehicle tailgate structure, and a vehicle to solve the problem that existing high-mounted brake lights affect the overall aesthetics of the tailgate.

[0006] To achieve the above objectives, this application provides a concealed high-mounted brake light, comprising: Rear windshield; The tailgate sheet metal part, wherein the rear windshield and the tailgate sheet metal part are disposed opposite to each other and have a first gap; A refractive glass plate, wherein the refractive glass plate is disposed within the first gap; A shielding component, the opposite ends of which respectively overlap the rear windshield and the tailgate sheet metal component, the shielding component, the rear windshield and the tailgate sheet metal component forming a mounting cavity; the mounting cavity communicates with the first gap; A light-emitting element is disposed within the mounting cavity and has a second gap between it and the rear windshield; the light emitted by the light-emitting element can enter the first gap through the second gap and exit through the rear windshield.

[0007] Optionally, the refracting glass is connected to the tailgate sheet metal, and the light emitted by the light-emitting element is refracted from the side through the end face of the refracting glass to the outside of the rear windshield.

[0008] Optionally, the light-emitting surface of the light-emitting element is opposite to and spaced apart from the end face of the refracting glass sheet; the light-emitting surface forms an obtuse angle between the incident line and the exit line formed on the refracting glass sheet.

[0009] Optionally, the refracting glass sheet includes a refracting segment and an inner segment arranged sequentially. The refracting segment has at least one refracting part on its surface facing the rear windshield. The incident line enters from the end face of the refracting segment, the exit line exits from the refracting part, and the inner segment is attached to the rear windshield.

[0010] Optionally, the refractive part is a plurality of protrusions connected in sequence, the protrusions protruding from one side of the tailgate sheet metal part toward the side of the rear windshield.

[0011] Optionally, the protrusion has a wedge-shaped or triangular structure, with the right-angled side of the wedge-shaped or triangular structure facing the end face of the refractive section, and the inclined surface of the wedge-shaped or triangular structure fitting against the rear windshield.

[0012] Optionally, the refracting glass sheet and the back door sheet metal are bonded together.

[0013] Optionally, a glass adhesive layer is provided between the refracting glass sheet and the back door sheet metal part.

[0014] Optionally, the shielding member is provided with a decorative layer.

[0015] Optionally, the rear windshield has a privacy liner on the surface facing away from the refractive glass; and / or the rear windshield is made of privacy glass.

[0016] Optionally, the refractive glass, the rear windshield, and the privacy sheet form an integrated composite structure.

[0017] Optionally, the light-emitting element is suspended within the mounting cavity and located outside the projection area of ​​the rear windshield.

[0018] Optionally, the light-emitting element can be detachably connected to the sheet metal part of the rear door.

[0019] This application also provides a vehicle tailgate structure, the vehicle tailgate structure including: a concealed high-mounted brake light as described above.

[0020] This application also provides a vehicle that includes: a concealed high-mounted brake light as described above.

[0021] As can be seen from the above, the concealed high-mounted brake light, vehicle tailgate structure, and vehicle provided in this application have the following advantages compared with the prior art: With the aforementioned concealed high-mounted brake light, only the obstruction, rear windshield, and tailgate sheet metal are visible. The light-emitting element is not visible from any position, whether viewed through the rear windshield from outside the vehicle, from the body panels inside the vehicle, or from any other location, ensuring the overall integrity of the design. The light-emitting element is located within the mounting cavity and refracts light from above the rear windshield through a refracting glass plate in the first gap. When the vehicle brakes, the high-mounted brake light effectively illuminates, enhancing the ability of following vehicles to recognize the brake signal, reducing the risk of rear-end collisions, and improving safety performance. Simultaneously, the rear windshield and tailgate sheet metal are positioned opposite each other, and the refracting glass plate is flush with the rear windshield. When the vehicle is stationary or in normal driving, there is no localized projection on the rear windshield. When observing the rear windshield from the outside of the vehicle, there is no obvious black area, thus ensuring the overall integrity of the rear windshield design and the vehicle's overall appearance, enhancing aesthetics.

[0031] Figure 1 This is an external schematic diagram of the concealed high-mounted brake light used in a specific embodiment of this application. Figure 2 for Figure 1 The exploded view shown is of the concealed high-mounted brake light. Figure 3 for Figure 1 The cross-sectional view at point AA of the concealed high-mounted brake light shown. Figure 4 for Figure 3 A magnified view of section B of the concealed high-mounted brake light shown. Figures 1 to 4 As shown, the concealed high-mounted brake light includes a rear windshield 2, a tailgate sheet metal part 3, a refracting glass piece 22, a shielding part 1, and a light-emitting part 4.

[0032] The rear windshield 2 is an important component of the vehicle's windshield. The front windshield and the rear windshield 2 are located in the front and rear window frames of the vehicle, respectively. The shape of the rear windshield 2 is usually, but is not limited to, rectangular glass. From a spatial point of view, the rear windshield 2 may be flat glass or curved glass.

[0033] In one embodiment of this application, the rear windshield 2 is typically made of at least one of laminated glass, tempered glass, zone-tempered glass, laminated zone-tempered glass, and acrylic glass. The rear windshield 2 has sufficient structural strength and good sound and heat insulation performance.

[0034] The rear windshield 2 and the tailgate sheet metal 3 are arranged opposite each other and have a first gap; a refracting glass sheet 22 is disposed within the first gap; the tailgate sheet metal 3 is zigzag-shaped, including an upper section, a middle section, and a lower section arranged sequentially, with a relatively smooth transition between the upper and middle sections, and an angle between the middle and lower sections. A window is provided on the middle section, and the middle sections of the rear windshield 2 and the tailgate sheet metal 3 are arranged opposite each other and have a first gap. The first gap may be slightly larger than the thickness of the refracting glass sheet 22 and is used to accommodate the refracting glass sheet 22. The circumferential edge of the rear windshield 2 overlaps the circumferential edge of the middle section of the tailgate sheet metal 3 and is used to close the window.

[0035] In one embodiment of this application, a refracting glass sheet 22 is provided on the surface of the rear windshield 2 facing the tailgate sheet 3. The two can be integrally formed or composite formed by superimposing different layers. The rear windshield 2 is stably connected to the tailgate sheet 3 by the circumferential edge of the refracting glass sheet 22 and the circumferential edge of the middle section between the tailgate sheet 3.

[0036] In one embodiment of this application, the structure of the refracting glass sheet 22 is adapted to the structure of the rear windshield 2. Similar to the rear windshield 2, the shape of the refracting glass sheet 22 is generally including but not limited to rectangular glass. From a spatial point of view, the refracting glass sheet 22 may be flat glass or curved glass. The refracting glass sheet 22 is generally made of at least one of laminated glass, tempered glass, zone tempered glass, laminated zone tempered glass and plexiglass.

[0037] The two ends of the shield 1 overlap the rear windshield 2 and the tailgate sheet metal 3, respectively. The shield 1, the rear windshield 2, and the tailgate sheet metal 3 form a mounting cavity. The mounting cavity is connected to the first gap. The shield 1 and the tailgate sheet metal 3 are positioned opposite each other, and the mounting cavity is a relatively sealed cavity. The light-emitting element 4 cannot be seen from either the shield side or the tailgate sheet metal 3 side. During assembly, the light-emitting element 4 is assembled onto the tailgate sheet metal 3, and then the shield 1 is placed over the outside of the light-emitting element 4, thereby ensuring that the light-emitting element 4 is in a relatively sealed environment. The light-emitting element 4 cannot be seen from either the outside or the inside of the vehicle, and the light-emitting element 4 can provide illumination into the first gap.

[0038] The light-emitting element 4 is disposed within the mounting cavity and has a second gap between it and the rear windshield 2; the light emitted by the light-emitting element 4 can enter the first gap through the second gap and exit through the rear windshield 2. In order to avoid the main structure of the light-emitting element 4 being visible from the outside of the rear windshield 2, and to ensure that the light is effectively emitted, there is a second gap between the light-emitting element 4 and the rear windshield 2.

[0039] The concealed high-mounted brake light can be applied to vehicles, including but not limited to those that can be used on vehicles. When the vehicle is braking, the light-emitting element 4 in the concealed high-mounted brake light is illuminated. The light from the light-emitting element 4 is refracted by the refracting glass plate 22 and emitted through the rear windshield 2 along the light emission direction, thus serving as a warning. When the vehicle is not braking, the light-emitting element 4 in the concealed high-mounted brake light is off. When observing the rear windshield 2 from the outside, i.e., from the opposite direction of the light emission direction, the light-emitting element 4 cannot be observed. At the same time, the mounting cavity formed by the shielding element 1 and the tailgate sheet metal 3 blocks the light-emitting element 4, making it impossible to observe the light-emitting element 4 from other positions. Furthermore, the internal structure of the concealed high-mounted brake light is completely invisible. From the outside, only the complete shielding element 1 and the rear windshield 2 are visible.

[0040] The concealed high-mounted brake light provided in this embodiment is so well-designed that only the obstruction 1, rear windshield 2, and tailgate sheet metal 3 are visible. The light-emitting element 4 is not visible from either the rear windshield 2 or other locations, ensuring the overall integrity of the design. The light-emitting element 4 is located within the mounting cavity and refracts light from above the rear windshield 2 through a refractive glass plate 22 in the first gap. When the vehicle brakes, the high-mounted brake light effectively illuminates, enhancing the ability of following vehicles to recognize the brake signal, reducing the risk of rear-end collisions, and improving safety. Furthermore, the rear windshield 2 and tailgate sheet metal 3 are positioned opposite each other, and the refractive glass plate 22 is flush with the rear windshield 2. When the vehicle is stationary or in normal driving, there is no localized projection on the rear windshield 2. When viewed from the outside of the vehicle, there is no obvious black area on the rear windshield 2, thus ensuring the overall integrity of the rear windshield 2 and enhancing its aesthetic appeal.

[0041] See also Figure 3 and Figure 4Optionally, the refracting glass plate 22 is connected to the tailgate sheet metal 3, and the light emitted by the light-emitting element 4 is refracted from the side through the end face of the refracting glass plate 22 to the outside of the rear windshield 2. The tailgate sheet metal 3 has a relatively large structure, and the refracting glass plate 22 is set on the middle section of the tailgate sheet metal 3. The light-emitting element 4 is set opposite to the upper section of the tailgate sheet metal 3, which allows the refracting glass plate 22 to be connected to a larger connecting base. This can relatively ensure a more stable connection between the refracting glass plate 22 and the rear windshield 2, making the position of the refracting glass plate 22 and the rear windshield 2 more stable.

[0042] In some feasible embodiments of this application, the refracting glass sheet 22 is connected to the back door sheet metal 3 through its bottom surface. Typically, the two ends of the refracting glass sheet 22 are provided with connection areas around the outer perimeter of the window. The connection between the refracting glass sheet 22 and the back door sheet metal 3 is achieved through the connection areas, so that there is still a certain gap between the bottom surface of the refracting glass sheet 22 and the back door sheet metal 3.

[0043] To facilitate more effective refraction of the light emitted from the light-emitting element 4 by the refracting glass plate 22, one end face of the refracting glass plate 22 faces the light-emitting surface 41 of the light-emitting element 4. Simultaneously, the rear windshield 2 is offset from the light-emitting element 4, so that the light emitted from the light-emitting surface 41 of the light-emitting element 4 enters the refracting glass plate 22 through its end face, is refracted by the refracting glass plate 22, and then exits through the rear windshield 2. Since the light-emitting element 4 is located on one side of the refracting glass plate 22, when the light-emitting element 4 is not lit, the rear windshield 2 blocks the refracting glass plate 22, making the light-emitting element 4 invisible.

[0044] More preferably, a focusing structure is also provided on the end face of the refracting glass plate 22 to concentrate the light from the light-emitting element 4 onto the refracting glass plate 22. The focusing structure includes, but is not limited to, a bowl-shaped structure or an arc-shaped structure. Through the bowl-shaped structure or arc-shaped structure, light located at the edge can be refracted and focused towards the center of the optical axis, thereby allowing more light to enter the refracting glass plate 22 and ensuring the brightness of the light spot. Correspondingly, a similar focusing structure can also be provided on the light-emitting surface 41 of the light-emitting element 4 to reduce light escape.

[0045] To further reduce light escape, a light-shielding structure is provided between the end face of the refracting glass plate 22 and the light-emitting surface 41 of the light-emitting element 4. This light-shielding structure ensures that the light emitted by the light-emitting element 4 propagates only in the direction of the refracting glass plate 22. Light propagating in other directions is blocked and refracted to the direction of the refracting glass plate 22. While ensuring sufficient light propagates to the refracting glass plate 22, this effectively reduces light escape and prevents light from leaking out from the gaps between the shielding element 1 and the rear windshield 2, and between the shielding element 1 and the tailgate sheet metal 3.

[0046] Furthermore, to achieve an effective connection between the refracting glass sheet 22 and the rear door sheet metal part 3, the refracting glass sheet 22 and the rear door sheet metal part 3 can optionally be bonded together. This bonding method is suitable for load-bearing, provides a seal, and is resistant to temperature-induced deformation. It also simplifies and simplifies operation, reduces manufacturing costs, and provides a more convenient and efficient connection.

[0047] To further simplify the assembly process and achieve a stable connection, optionally, a glass adhesive layer 21 is provided between the refracting glass sheet 22 and the back door sheet metal part 3. The refracting glass sheet 22 is adhered to the back door sheet metal part 3 by means of, but is not limited to, the glass adhesive layer 21. The glass adhesive layer 21 forms between the refracting glass sheet 22 and the back door sheet metal part 3. The glass adhesive layer 21 can better bond the refracting glass sheet 22 and also provide a good seal for the light-emitting element 4, playing a good waterproof role. It can effectively prevent the intrusion of water vapor and dust and prevent leakage from damaging the light-emitting element 4.

[0048] See also Figure 3 and Figure 4 To better conceal the light-emitting element 4, optionally, the light-emitting surface 41 of the light-emitting element 4 is positioned opposite and spaced apart from the end face of the refracting glass plate 22; the incident line and the exit line formed by the light-emitting surface 41 on the refracting glass plate 22 form an obtuse angle. By setting the installation position and angle of the light-emitting element 4, a certain distance is maintained between the light-emitting element 4 and the refracting glass plate 22, preventing the projection of the light-emitting element 4 from being refracted from the edge of the refracting glass plate 22, thereby better concealing the light-emitting element 4.

[0049] In one embodiment of this application, the value of this distance needs to be set such that the light-emitting element 4 cannot be observed at the edge of the refracting glass plate 22, while also ensuring that the light from the light-emitting element 4 can penetrate into the refracting glass plate 22 to a large extent. By setting the angle between the incident line and the exit line to an obtuse angle, the light can be concentrated towards the center area of ​​the rear windshield 2, making the emitted light spot more concentrated, brighter, and with stronger penetrating power, thus achieving a better warning effect.

[0050] See also Figure 3 and Figure 4The shape of the refracting glass plate 22 is set according to the shape of the refraction area and the rear windshield 2. Optionally, the refracting glass plate 22 includes a refraction section 221 and an inner section 222 arranged sequentially. The surface of the refraction section 221 facing the rear windshield 2 is provided with at least one refraction part. The incident light enters from the end face of the refraction section 221, and the outgoing light exits from the refraction part. The inner section 222 is attached to the rear windshield 2. The end face of the side of the refraction section 221 faces the light-emitting surface 41 of the light-emitting element 4. The light emitted from the light-emitting element 4 enters the refraction section 221 through the end face of the refraction section 221, and after being refracted by the refraction part on the refraction section 221, it is emitted to the rear windshield 2 and then emitted out of the rear windshield 2. The refraction section 221 can converge and refract light of different angles toward the rear windshield 2, so that the light spot is concentrated and the brightness of the light spot is improved. By incorporating the inner segment 222, the size of the refracting glass plate 22 can be effectively increased, such as by increasing its length. This increases the contact area between the refracting glass plate 22 and the tailgate sheet metal 3, thereby improving the connection stability between them. Furthermore, the inner segment 222 also provides effective support for the rear windshield 2, preventing any partial suspension during assembly and enhancing its connection stability.

[0051] The refraction section is designed according to the width of the high-mounted brake light strip. The wider the high-mounted brake light strip, the longer the refraction section. Optionally, the refraction section consists of multiple protrusions connected in sequence, protruding from one side of the tailgate sheet metal 3 towards the side of the rear windshield 2. The light emitted from the light-emitting element 4 enters the refraction section 221 through the end face of the refraction section 221. Based on the multiple protrusions, the optical fiber is refracted multiple times and at multiple angles, so that the optical fiber entering from the end face can be concentrated towards the central area of ​​the rear windshield 2, making the light spot formed by the light emitted from the rear windshield 2 more concentrated, brighter, and with stronger penetration.

[0052] To further simplify the structure of the refractive plate 22, the protrusion can optionally be wedge-shaped or triangular, with the right-angled side of the wedge or triangle facing the end face of the refractive section 221, and the inclined surface of the wedge or triangle fitting against the rear windshield 2. This arrangement creates a sawtooth shape from multiple wedges or triangles, which, combined with the bottom of the refractive section 221, form a structure similar to a Fresnel lens. Light enters the refractive section 221 from one side of the wedge or triangle of the Fresnel lens, and is obliquely incident on the inclined optical working surface of the sawtooth of the wedge or triangle. The light is deflected towards the normal, bending towards the optical axis of the refractive section 221. Simultaneously, the light propagates straight through the interior of the refractive section 221 to the flat exit surface on the other side, and then travels from the medium of the refractive section 221 into the air. Here, the light changes from denser to less dense, undergoing refraction again and further deflecting towards the optical axis. The inclined angle of each wedge or triangle is precisely designed, ensuring that the light refracted by all the wedges or triangles converges to the same focal point, achieving a good light-gathering effect.

[0053] The shielding component 1 is used to cover the light-emitting component 4, making the light-emitting component 4 invisible in appearance. To make the overall structure more aesthetically pleasing, the shielding component 1 may optionally be provided with a decorative layer. While decorating the overall structure with the decorative layer, it can also further distract attention and reduce the probability of observing the light-emitting component 4 from the outside.

[0054] In some achievable embodiments of this application, the shielding member 4 includes a shielding section and a first overlapping section and a second overlapping section extending from opposite ends of the shielding section. The shielding section is opposite to and spaced apart from the light-emitting member 4. The free end of the first overlapping section overlaps the end face of the upper section of the tailgate sheet metal member 3, and the free end of the second overlapping section overlaps the upper end face of the rear windshield 2. The length of the first overlapping section is greater than the length of the second overlapping section. The included angle between the first overlapping section and the shielding section is the first included angle, and the included angle between the second overlapping section and the shielding section is the second included angle. Both the first included angle and the second included angle are obtuse angles, and the angle of the second included angle is greater than the angle of the first included angle.

[0055] To better shield the light-emitting element 4, optionally, a privacy pane 23 may be provided on the surface of the rear windshield 2 facing away from the refractive glass pane 22; and / or the rear windshield 2 may be made of privacy glass. The privacy pane 23 and the privacy glass serve to prevent peeping. When observing the rear windshield 2 in the opposite direction of the light emission direction, objects inside the rear windshield 2 cannot be seen, thus allowing the rear windshield 2 to better shield the light-emitting element 4. When the light-emitting element 4 is not lit, it is not visible from the outside, and the internal structure of the concealed high-mounted brake light is also completely invisible. At the same time, it should be ensured that the refracted light emitted by the light-emitting element 4 can be effectively projected and refracted from the privacy pane 23 and the privacy glass so that pedestrians or drivers can effectively identify it.

[0056] See also Figure 3 and Figure 4 Optionally, the refractive glass 22, the rear windshield 2, and the privacy pane 23 can be integrated into a single composite structure. This allows for more convenient and faster assembly, while also improving structural strength and resistance to external impacts, thus reducing damage to the rear windshield 2 and the refractive glass 22.

[0057] See also Figure 3 and Figure 4 Optionally, the light-emitting element 4 is suspended within the mounting cavity and located outside the projection area of ​​the rear windshield 2. When the concealed high-mounted brake light is applied to a vehicle, if the vehicle remains outdoors for an extended period under direct sunlight, the temperature of the shield 1 and the tailgate sheet metal 3 will rise, potentially damaging the light-emitting element 4. Therefore, suspending the light-emitting element 4 within the mounting cavity prevents it from contacting the shield 1 and tailgate sheet metal 3, thus reducing the impact of heat from these components on the light-emitting element 4. Furthermore, the light-emitting element 4 also generates heat during operation; its suspension allows for airflow around its periphery, facilitating heat dissipation. By placing the light-emitting element 4 outside the projection area of ​​the rear windshield 2, it is possible to make the light-emitting element 4 invisible in appearance, and also to reduce the direct sunlight from shining through the rear windshield 2 onto the light-emitting element 4, thus reducing the temperature rise caused by direct sunlight.

[0058] Optionally, the light-emitting element 4 can be detachably connected to the rear door sheet metal part 3. This detachable connection facilitates the installation and removal of the light-emitting element 4. It also allows for timely maintenance or replacement of the light-emitting element 4 should any problems arise.

[0059] In some feasible embodiments of this application, a detachable connection method is as follows: the light-emitting element 4 is mounted on the back door sheet metal part 3 with a nut hole 31 by bolts 5. The light-emitting element 4 can also be detachably connected to the back door sheet metal part 3 by snap-fit, for example, by setting a matching concave-convex shape snap-fit ​​structure between the light-emitting element 4 and the back door sheet metal part 3, so that when the light-emitting element 4 is connected to the back door sheet metal part 3, the concave-convex shape snap-fit ​​structure plays a role in positioning and mutual engagement, and when the light-emitting element 4 moves relative to the back door sheet metal part 3 and the moving force exceeds a certain limit, the concave-convex shape snap-fit ​​structure separates, thereby allowing the light-emitting element 4 to be removed from the back door sheet metal part 3.

[0060] The following section uses the example of a concealed high-mounted brake light on a vehicle to further illustrate the usage process of a concealed high-mounted brake light.

[0061] When the vehicle is braking, the light-emitting element 4 in the concealed high-mounted brake light is illuminated. The light from the light-emitting element 4 can be refracted by the refracting glass plate 22 and emitted through the rear windshield 2 along the light emission direction of the rear windshield 2, thereby serving as a warning.

[0062] When the vehicle is not braking, the light-emitting element 4 of the concealed high-mounted brake light is off. When observing the rear windshield 2 from the outside, that is, from the opposite direction of the light emission direction, the light-emitting element 4 cannot be observed. At the same time, since the light-emitting element 4 is blocked by the shielding element 1, it cannot be observed from other positions.

[0063] This application also provides a vehicle tailgate structure, which includes a concealed high-mounted brake light as described in the above embodiments. The implementation of the concealed high-mounted brake light can be referenced or adapted from the implementation methods described in the above embodiments, and will not be elaborated further here.

[0064] When the aforementioned tailgate structure is installed on the vehicle, the light-emitting element 4 in the concealed high-mounted brake light is illuminated when the vehicle is braking. The light from the light-emitting element 4 is refracted by the refracting glass plate 22 and emitted through the rear windshield 2 along the light emission direction, thus serving as a warning. When the vehicle is not braking, the light-emitting element 4 in the concealed high-mounted brake light is off. When observing the rear windshield 2 from the outside, i.e., from the opposite direction of the light emission direction, the light-emitting element 4 cannot be observed. Furthermore, since the light-emitting element 4 is blocked by the blocking component 1, it cannot be observed from other positions.

[0065] The vehicle's tailgate structure employs the aforementioned concealed high-mounted brake light. Only the obstruction, rear windshield, and tailgate sheet metal are visible. The light source is invisible from any external view through the rear windshield, from within the body panels, or from any other location, ensuring a seamless and unified aesthetic. The light source is located within the mounting cavity and refracts light from above the rear windshield through a refracting glass plate in the first gap. When the vehicle brakes, the high-mounted brake light effectively illuminates, enhancing the ability of following vehicles to recognize the brake signal, reducing the risk of rear-end collisions, and improving safety. Furthermore, the rear windshield and tailgate sheet metal are positioned opposite each other, and the refracting glass plate is flush with the rear windshield. When the vehicle is stationary or in normal driving, there is no localized projection on the rear windshield. Viewed from the outside of the vehicle, the rear windshield does not show any noticeable black areas, further ensuring the rear windshield's design remains integrated with the overall vehicle design and enhancing aesthetics.

[0066] This application also provides a vehicle, which includes a concealed high-mounted brake light as described in the above embodiments. The implementation of the concealed high-mounted brake light can be referenced or adapted from the implementation methods described in the above embodiments, and will not be elaborated further here.

[0067] When the vehicle is braking, the light-emitting element 4 in the concealed high-mounted brake light is illuminated. The light from the light-emitting element 4 is refracted by the refracting glass plate 22 and emitted through the rear windshield 2 along the light emission direction, thus serving as a warning. When the vehicle is not braking, the light-emitting element 4 in the concealed high-mounted brake light is off. When observing the rear windshield 2 from the outside, i.e., from the opposite direction of the light emission direction, the light-emitting element 4 cannot be observed. At the same time, because the blocking element 1 blocks the light-emitting element 4, it cannot be observed from other positions.

[0068] The vehicle employs the aforementioned concealed high-mounted brake light, making it visible only from the obstruction, rear windshield, and tailgate sheet metal. The light source is invisible from any external view through the rear windshield, from within the body panels, or from any other location, ensuring a seamless and unified appearance. The light source is located within the mounting cavity and refracts light from above the rear windshield through a refracting glass plate in the first gap. When the vehicle brakes, the high-mounted brake light effectively illuminates, enhancing the ability of following vehicles to recognize the brake signal, reducing the risk of rear-end collisions, and improving safety. Furthermore, the rear windshield and tailgate sheet metal are positioned opposite each other, and the refracting glass plate is flush with the rear windshield. When the vehicle is stationary or in normal driving, there is no localized projection on the rear windshield. Viewed from the outside of the vehicle, the rear windshield does not show any noticeable black areas, further ensuring the rear windshield's design remains integrated with the overall vehicle design and enhancing aesthetics.

[0069] It should be noted that the concealed high-mounted brake light provided in this application can be applied not only to the vehicle's tailgate structure and the vehicle itself, but also to other lighting scenarios according to different needs.

[0070] As can be seen from the above description and practice, the concealed high-mounted brake light, vehicle tailgate structure, and vehicle provided in this application have the following advantages compared with the prior art: With the aforementioned concealed high-mounted brake light, only the obstruction, rear windshield, and tailgate sheet metal are visible. The light-emitting element is not observable from any position, whether viewed through the rear windshield from the outside of the vehicle, from the body panels inside the vehicle, or from any other location, ensuring the overall integrity of the appearance. The light-emitting element is located within the mounting cavity and refracts light from the upper part of the rear windshield through a refracting glass plate in the first gap. When the vehicle brakes, the high-mounted brake light can be effectively displayed, enhancing the ability of following vehicles to recognize the brake signal, reducing the risk of rear-end collisions, and improving safety performance. Simultaneously, the rear windshield and tailgate sheet metal are positioned opposite each other, and the refracting glass plate is flush with the rear windshield. When the vehicle is stationary or in normal driving, there is no localized projection on the rear windshield. When observing the rear windshield from the outside of the vehicle, there is no obvious black area, thus ensuring the overall integrity of the rear windshield design and the vehicle's overall appearance, enhancing aesthetics.

[0071] Those skilled in the art should understand that the above description is merely a specific embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the scope of this application should be included within the protection scope of this application.
