Description

Technical Field

[0001] This application relates to the technical field of automotive parts, and particularly relates to a high-mounted brake light and a motor vehicle. Background Art

[0002] With the rapid development of the economy, the number of automobiles has been increasing year by year. Accidents caused by rear-end collisions of automobiles are also increasing year by year. Therefore, while developing the economy, ensuring traffic safety is an important social security issue.

[0003] In related technologies, an automobile displays its braking state through brake lights distributed at both ends. Since the installation position of the brake lights is relatively low, when the following vehicle is relatively close behind, the front of the following vehicle will block the brake lights of the vehicle in front, resulting in the driver of the following vehicle being unable to judge whether the vehicle in front has taken braking action through the brake lights, posing a risk of rear-end collision.

[0004] To solve the above problems, in related technologies, a high-mounted brake light is provided at the rear of the automobile as an auxiliary light for the brake lights. It is generally installed on the center line at the rear end of the vehicle, with a height higher than that of the brake lights, so that when the following vehicle is relatively close behind, the driver of the following vehicle can still judge whether the vehicle in front has taken braking action based on the high-mounted brake light.

[0005] The lamp cover and lamp housing of the high-mounted brake light are arc-shaped along the body direction, while the PCB board is a rigid straight board. To install the rigid straight PCB board in the lamp cover and lamp housing, it is necessary to increase the size of the lamp cover and / or lamp base in the direction of its own thickness and length, resulting in a relatively large thickness dimension of the entire lamp. Moreover, since the distances between different positions of the rigid straight PCB board and the arc-shaped lamp cover are not equal, the lighting effects at various parts of the lamp cover are inconsistent, and an inner lamp cover needs to be added to improve the lighting effect of the lamp cover, resulting in an increase in the cost of the entire lamp.

[0006] Therefore, how to solve the problems of large overall size and high cost of the high-mounted brake light has become a technical problem that needs to be urgently solved by those skilled in the art. Utility Model Content

[0007] This application proposes a high-mounted brake light to solve the problems of large overall size and high cost of the high-mounted brake light. This application also proposes a motor vehicle.

[0008] To achieve the above object, this application provides a high-mounted brake light, including a lamp cover, a light-emitting element, and a lamp base. The lamp cover is connected to the lamp base to enclose a closed space for installing the light-emitting element. The light-emitting element is connected to the lamp base.

[0009] The lamp cover and the lamp base are arc-shaped along their own length directions. An optical pattern is provided on the side of the lamp cover facing the lamp base.

[0010] The PCB board of the light-emitting element is arc-shaped along the length direction of the lamp cover.

[0011] Preferably, in the above high-mounted stop lamp, the lamp cover is arc-shaped along its own width direction.

[0018] Preferably, in the above high-mounted stop lamp, a connecting plate is arranged circumferentially on the lamp cover, the lamp cover is connected to the lamp base through the connecting plate, and the lamp cover, the connecting plate, and the lamp base enclose the closed space.

The lamp cover and the lamp base are arc-shaped along their own length directions according to the body shape design. The PCB board of the light-emitting element is also arc-shaped along the length direction of the lamp cover and is adapted to the shapes of the lamp base and the lamp cover.

[0036] Please refer to Figures 1-4 。

[0037] Some embodiments of the present application disclose a high-level brake light, including a lamp cover 1, a light-emitting element 2, and a lamp socket 3.

[0038] The lamp cover 1 is connected to the lamp socket 3 to enclose a closed space for installing the light-emitting element 2. The light-emitting element 2 is connected to the lamp socket 3, and the light emitted by the light-emitting element 2 is emitted through the lamp cover 1.

[0039] In some embodiments, the lamp cover 1 and the lamp socket 3 are arc-shaped along their own length directions following the body shape design, and the PCB board of the light-emitting element 2 is also arc-shaped along the length direction of the lamp cover 1. Specifically, the lamp socket 3 is provided with a fixing member for fixing the PCB board of the light-emitting element 2. After the PCB board is fixed to the lamp socket 3 through the fixing member, the PCB board forms a curved panel, and the lamp cover 1 is designed to conform to the PCB board; or the PCB board is processed into an arc shape, and the arc-shaped PCB board is connected to the lamp socket 3.

[0040] The arcs of the lamp shade 1 and the lamp base 3 are designed according to the body trend, which not only reduces the fitting difficulty between the lamp shade 1 and the lamp base 3, but also optimizes the fitting effect between the high-mounted stop lamp and the vehicle body.

[0041] For the high-mounted stop lamp disclosed in this application, the PCB board of the light-emitting element 2 is arc-shaped and adapted to the shapes of the lamp base 3 and the lamp shade 1. Compared with a rigid straight PCB board, the dimensions of the lamp base 3 and the lamp shade 1 in their own length direction and thickness direction can be reduced, so as to reduce the size of the whole lamp;

[0042] Meanwhile, the distance between the PCB board and various parts of the lamp shade 1 is improved, and correspondingly, the lighting effect of the lamp shade 1 is improved. The inner lamp shade 1 is omitted, the number of parts of the high-mounted stop lamp is reduced, and the processing cost of the high-mounted stop lamp is lowered.

[0043] An optical pattern is provided on the inner wall of the lamp shade 1 facing the lamp base 3. The optical pattern can not only refract light to expand the irradiation range, but also make the light softer, improving night driving safety.

[0044] Specifically, the optical pattern is at least one of a cylindrical pattern, a corn kernel pattern, and a vertical stripe pattern.

[0045] Such as Figure 3 and Figure 4 shown, the lamp shade 1 is arc-shaped along its own width direction. In this embodiment, the lamp shade 1 is arc-shaped along both its own length direction and width direction, which can optimize the refraction and scattering effects of the lamp shade 1 on light;

[0046] In some embodiments, the included angle between the lamp beads of the light-emitting element 2 and the normal direction of the lamp shade 1 corresponding to the positions of the lamp beads is 85° - 95°, preferably 90°. This reduces the occupied space of the light-emitting element 2 and can further reduce the size of the high-mounted stop lamp to a certain extent; on the other hand, it can also reduce the material used for the lamp base 3 and the lamp shade 1, lowering the cost of the high-mounted stop lamp.

[0047] In some embodiments, the light-emitting element 2 is an LED module. After the LED module is fixed to the lamp base 3, the rigid straight plate LED module is bent into a curved panel, and the lamp shade 1 conforms to the shape of the LED module.

[0048] The included angle between the axis of each lamp bead of the LED module and the normal direction of the lamp shade 1 corresponding to the position of the lamp bead is 85° - 95°, preferably 90°. The curved surface rigid LED module and the lamp shade 1 with a curved surface shape can be conformally covered, and the occupied space of the LED module inside the lamp can be reduced.

[0049] In some embodiments, the light-emitting element 2 is a light guide bar.

[0050] The light-emitting element 2 is not limited to the above two embodiments, and may also be other forms of light-emitting elements 2, which are not specifically defined herein.

[0051] The lamp cover 1 is a transparent lamp cover or a colored lamp cover. The light color of the high-mounted stop lamp can be determined by the light-emitting element 2, or by the lamp cover 1, or jointly determined by the light-emitting element 2 and the lamp cover 1.

[0052] In some embodiments, the cross-section of the lamp holder 3 along the direction perpendicular to its own length is L-shaped, and the angle of the L-shape is at least 90°. The lamp cover 1 is located in the opening direction of the L-shape and seals the opening. As Figure 3 and Figure 4 shown, the cross-section of the enclosed space along the direction perpendicular to the length of the lamp cover 1 is fan-shaped.

[0053] A connecting plate 4 is arranged circumferentially on the lamp cover 1. The lamp cover 1 is connected to the lamp holder 3 through the connecting plate 4, and the lamp cover 1, the connecting plate 4 and the lamp holder 3 enclose a closed space.

[0054] The connecting plate 4 and the lamp cover 1 can be integrally formed or connected through a mechanical structure.

[0055] In the embodiment where the connecting plate 4 and the lamp cover 1 are connected through a mechanical structure, the connecting plate 4 and the lamp cover 1 are connected by welding, bolt connection or bonding.

[0056] There are various connection methods between the connecting plate 4 and the lamp holder 3, such as bolt connection, plug connection, welding or bonding, etc.

[0057] In the embodiment where the connecting plate 4 and the lamp holder 3 are connected by plug connection, a slot cooperating with the connecting plate 4 is provided on the lamp holder 3, and the connecting plate 4 is connected to the lamp holder 3 through the slot.

[0058] In some embodiments, the light-emitting element 2 and the lamp holder 3 are connected by bolt connection, or the light-emitting element 2 and the lamp holder 3 are connected by snap connection.

[0059] In the embodiment where the light-emitting element 2 and the lamp holder 3 are connected by bolt connection, threaded holes are opened on the light-emitting element 2 and the lamp holder 3, and the light-emitting element 2 and the lamp holder 3 are connected by bolts cooperating with the threaded holes.

[0060] In the embodiment where the light-emitting element 2 and the lamp holder 3 are connected by snap connection, a snap connection portion is provided on the lamp holder 3, and the snap connection portion is arranged along the arc of the lamp holder 3, and the light-emitting element 2 is connected to the lamp holder 3 through the snap connection portion.

[0061] This application also discloses a motor vehicle, including a high-mounted stop lamp, and the high-mounted stop lamp is the high-mounted stop lamp described in any one of the above solutions.

[0062] Since the high-mounted stop lamp has the above technical effects, the motor vehicle having the high-mounted stop lamp also has the same technical effects, which will not be elaborated herein.

[0063] The above description is only a preferred embodiment of the present application and an explanation of the applied technical principles, and is not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. The scope of the application involved in the present application is not limited to the technical solutions formed by the specific combination of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above application concept.
