Description

TECHNICAL FIELD

[0001] The present application relates to the field of automobile high brake light applications, in particular to an LED tail light applied to an automobile rear light system. BACKGROUND

[0002] The automobile high brake light is a brake warning light installed on the upper part of the tail, also known as the third brake light, high brake light, and the installation position of the high brake light is higher than that of the ordinary brake light. It can break through the driver's visual blind area and make the drivers of high chassis vehicles such as trucks and buses aware of the brake signal earlier. In traffic-dense or complex road conditions, it can give the rear vehicle more reaction time. It is usually installed in the center of the vehicle tail or between the two tail lights, such as the trunk lid, rear roof or rear windshield.

[0003] In modern industrial vehicles, the high brake light is usually an LED light source composed of LED beads and PCB circuit boards. The beads are arrayed and welded on the circuit board, and some are also equipped with a condensing lens to improve the light concentration. The core light-emitting element of the LED bead is a semiconductor chip. The high brake light of a private car is only lit during braking, and the daily working time is very short. The service life can reach 8-15 years. However, the service life of taxi and truck vehicles is slightly reduced to 5-8 years due to high frequency of use.

[0004] The high brake light is eroded by environmental factors in actual use, such as low temperature and high temperature, which can accelerate the aging of the lampshade, cause the sealing element to fail, and further cause internal circuit short circuit or bead oxidation, resulting in premature damage. In addition, the LED beads generate heat during operation, and if the heat sink of the high brake light is not designed enough, it will also accelerate the aging of the beads and shorten the service life. The high brake light is usually an assembly, and due to the lack of professional knowledge of automobile users, they will choose to replace the entire component if the brake light does not light up, which greatly increases the after-sales cost of the user. In fact, the user can only purchase the corresponding LED light board from the Internet to replace it independently. SUMMARY

[0005] Therefore, the purpose of the present application is to provide an LED tail light applied to an automobile rear light system to solve the technical problems mentioned in the background.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an LED taillight for use in a car rear lighting system, comprising an outer mounting shell and a red lens, wherein an inner mounting shell is mounted on the inner side of the outer mounting shell, and a triangular mounting bracket is rotatably connected to the top of the inner mounting shell. The triangular mounting bracket comprises a triangular prism, and the sides of the triangular prism include three sets of mounting surfaces, each of which is equipped with an LED chip assembly. The interior of the triangular prism is hollowed out, and the three sets of mounting surfaces are connected to the interior space of the triangular prism. A power supply head is provided at one end of the triangular prism, and three sets of first... The socket has three sets of first sockets that are electrically connected to three sets of LED bead assemblies, and three sets of first contact plates are provided on the outside of the power supply head. The three sets of first contact plates and the three sets of first sockets are electrically connected respectively. The top of the inner mounting shell is provided with a power supply module, which includes a housing. The bottom of the housing is provided with a third socket that is connected to the vehicle data interface. One side of the housing is provided with a sleeve socket that matches the end of the power supply head. The inner side of the sleeve socket is provided with a second contact plate that matches the first contact plate. The other end of the triangular prism is connected to a drive mechanism.

In actual vehicle use, if the high-mounted brake light fails to illuminate, the user can quickly switch the LED components and replace the damaged ones with new ones, ensuring safe installation. Furthermore, the integration of multiple LED components into the brake light also extends the service life of the high-mounted brake light.

[0008] The invention is further configured such that the inner side of the outer mounting shell is provided with mounting feet for connecting to the vehicle body.

[0009] Preferably, by providing mounting brackets, the high-mounted brake light assembly can be fixed to the main body of the vehicle, such as the trunk or the inside of the rear windshield.

[0010] The present invention is further configured such that the triangular prism and the inner wall of the inner mounting shell are rotatably connected, and the side of the triangular prism is provided with multiple sets of heat dissipation holes, all of which are connected to the internal space of the triangular prism.

[0011] Preferably, heat dissipation holes are provided to improve the heat dissipation effect of the triangular prism itself, so that heat can be dissipated both inside and outside the triangular prism.

[0012] The present invention is further configured such that the lamp bead assembly includes a lamp board, the bottom of the lamp board is provided with a ribbon cable interface, the ribbon cable interface is matched with the first plug, and a focusing lens is movably installed on the top of the lamp board.

[0013] As preferably, by setting the lamp bead assembly with condenser lens, light effect is better, condenser lens is transparent material, outside can be attached with shaped shading material, thereby making different lamp bead assemblies emit light of different structure forms, such as "heart" type, "lightning" type.

[0014] The application is further provided that the three-prism is provided with a plurality of wire arranging holes near one end of the power supply head, and the wire arranging holes are used for penetrating the wire arranging interfaces of the lamp bead assemblies.

[0015] As preferably, by setting a plurality of wire arranging holes, the wire arranging interfaces penetrating the bottom of the lamp panel can be used, so that the three-prism mounting frame and the plurality of lamp bead assemblies are more closely mounted.

[0016] The application is further provided that the third socket of the power supply module extends to the outside of the inner mounting shell and is connected with the automobile data interface.

[0017] As preferably, by setting the power supply module, the plurality of lamp bead assemblies and the automobile data interface are connected, so that the user can control one group of lamp bead assemblies to work by stepping on the brake.

[0018] The application is further provided that the second electrically-conductive sheet is provided with a group on the inside of the sleeve socket, the second electrically-conductive sheet is electrically connected with the third socket, and the second electrically-conductive sheet faces the red lens, so that only one group of first electrically-conductive sheets is connected with the second electrically-conductive sheet in the rotating process of the three groups of first electrically-conductive sheets outside the power supply head.

[0019] As preferably, by setting the first electrically-conductive sheet and the second electrically-conductive sheet to supply power, the three-prism mounting frame can be connected with the automobile data interface through the power supply module in rotation, the second electrically-conductive sheet always faces the red lens, and only the lamp bead assembly facing the red lens is in working state.

[0020] The application is further provided that the driving mechanism includes a cover, the inside of the cover is provided with a driving device, and the driving device and the three-prism are drivingly connected through the gear set and the worm and gear assembly.

[0021] As preferably, by setting the driving mechanism to drive the three-prism mounting frame to rotate, the user can actively control the driving mechanism to realize the switching of different lamp bead assemblies.

[0022] The application is further provided that the side of the shell is provided with a second socket, the wire harness connection is arranged between the second socket and the driving mechanism, and the inside of the inner mounting shell is provided with a card and a wire harness groove.

[0023] As preferred, by setting the second socket, the driving mechanism can be connected through the setting of the wire harness and the power supply module, the power supply module is connected with the automobile computer, so that the user can independently control the driving mechanism of the high brake light assembly, and the wire harness slot can be clamped with the wire harness to reduce the shaking of the wire harness.

[0024] In summary, the present application mainly has the following beneficial effects: The present application can assemble multiple groups of lamp bead assemblies for the brake light assembly by setting the rotatable three-prong mounting bracket, so that the user can quickly switch the lamp bead assembly in the first time to replace the damaged lamp bead assembly with a new one to ensure driving safety in actual driving conditions, and the multiple groups of lamp bead assemblies integrated in the brake light can also prolong the service life of the high brake light.

[0025] The present application can prolong the service life of the high brake light as a whole by increasing the number of lamp bead assemblies, and improve the heat dissipation effect of the lamp bead assemblies through the unique structure of the three-prong mounting bracket, thereby prolonging the service life of each group of lamp bead assemblies. Compared with the traditional high brake light, the lamp bead plate is installed and connected with the screw column foot of the shell through screws, and some lamp bead plates are additionally provided with aluminum heat sinks, but the heat dissipation space at the back of the lamp bead plate or the heat dissipation space at the back of the aluminum heat sink is small, so that the local temperature of the lamp bead plate is relatively high. In the present application, the three-prong mounting bracket is designed to be hollow, and multiple groups of heat dissipation holes are formed in the three edges of the three-prong, so that the channels inside the three-prong increase the heat dissipation space of the lamp bead assemblies and allow the heat of the three-prong mounting bracket to be transferred inward and outward at the same time, so that the three-prong mounting bracket has good heat conduction effect. That is, the three-prong mounting bracket is equivalent to three groups of aluminum heat sinks connected with each other, which not only satisfies the installation of multiple groups of lamp bead assemblies, but also shares the same heat dissipation space, reduces the installation volume, and improves the heat dissipation effect of the three-prong itself, thereby prolonging the service life of each group of lamp bead assemblies.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] The embodiments of the present invention will now be described.

[0030] Please see Figure 1 - Figure 10An LED taillight for use in a car rear lighting system includes an outer mounting shell 1 and a red lens 2. The red lens 2 is used to display the LED light in red. An inner mounting shell 4 is installed inside the outer mounting shell 1. A triangular mounting bracket 5 is rotatably connected to the top of the inner mounting shell 4. The triangular mounting bracket 5 includes a triangular prism 501, which is made of aluminum. The side of the triangular prism 501 includes three sets of mounting surfaces, each of which is equipped with an LED bead assembly 6. The interior of the triangular prism 501 is hollowed out, and the three sets of mounting surfaces are connected to the interior space of the triangular prism 501. A power supply head 503 is provided at one end of the triangular prism 501. Three sets of first sockets 504 are provided on one side of the power supply head 503. The three sets of first sockets 504 are electrically connected to the three sets of LED bead assemblies 6 respectively. Three sets of first contact pieces 505 are provided on the outside of the power supply head 503. The three sets of first contact pieces 505 and the three sets of first sockets 504 are respectively connected to the three sets of LED bead assemblies 6. Corresponding to the electrical connection, a power supply module 8 is provided on the top of the inner mounting shell 4. The power supply module 8 includes a shell 801, a third socket 803 is provided at the bottom of the shell 801, the third socket 803 is connected to the vehicle data interface, and a sleeve socket 804 is provided on one side of the shell 801. The sleeve socket 804 matches the end of the power supply head 503, and a second contact piece 805 matching the first contact piece 505 is provided on the inner side of the sleeve socket 804. The other end of the triangular prism 501 is connected to a drive mechanism 7. By setting a rotatable triangular mounting bracket 5, multiple sets of lamp bead assemblies 6 can be assembled for the brake light assembly. Thus, in actual vehicle use, if the high-mounted brake light fails to light up, the user can quickly switch the lamp bead assembly 6 and use a new lamp bead assembly 6 to replace the damaged lamp bead assembly 6, ensuring driving safety. Moreover, the integration of multiple sets of lamp bead assemblies 6 into the brake light can also extend the service life of the high-mounted brake light.

[0031] Please refer to the above embodiments for further details. Figure 1 and Figure 2 The inner side of the outer mounting shell 1 is provided with mounting feet 3, which are used to connect with the main body of the car. By setting the mounting feet 3, the high-mounted brake light assembly can be fixed to the main body of the car, such as the trunk or the inside of the rear windshield. The specific choice depends on the different car models.

[0032] Please refer to the above embodiments for further details. Figure 6 The triangular prism 501 is rotatably connected to the inner wall of the inner mounting shell 4, and multiple sets of heat dissipation holes 502 are opened on the side of the triangular prism 501. All sets of heat dissipation holes 502 are connected to the internal space of the triangular prism 501. By setting the heat dissipation holes 502, the heat dissipation effect of the triangular prism 501 itself is improved, so that heat can be dissipated both inside and outside the triangular prism 501.

[0033] Please refer to the above embodiments for further details. Figure 8The LED assembly 6 includes a lamp board 601. A ribbon cable interface 602 is provided at the bottom of the lamp board 601. The ribbon cable interface 602 matches the first socket 504. A condenser lens 603 is movably installed on the top of the lamp board 601. By setting the LED assembly 6 with the condenser lens 603, the light effect is better. The condenser lens 603 is made of transparent material, and a light-shielding material with a shape can be attached to the outside, so that different LED assemblies 6 can emit light with different structural forms, such as "heart" shape and "lightning" shape.

[0034] Please refer to the above embodiments for further details. Figure 7 The triangular prism 501 has multiple sets of cable routing holes 506 at one end near the power supply head 503. The cable routing holes 506 are used to pass through the cable routing interface 602 of the LED bead assembly 6. By setting multiple sets of cable routing holes 506, the cable routing interface 602 at the bottom of the lamp board 601 can be passed through, making the installation of the triangular mounting bracket 5 and the multiple sets of LED bead assemblies 6 more compact.

[0035] Please refer to the above embodiments for further details. Figure 3 and Figure 10 The third port 803 of the power supply module 8 extends to the outside of the inner mounting shell 4 and interfaces with the vehicle data interface. By setting the power supply module 8, multiple sets of lamp bead assemblies 6 are connected to the vehicle data interface so that the user can control one set of lamp bead assemblies 6 to work by stepping on the brake.

[0036] Please refer to the above embodiments for further details. Figure 10 A set of second electrical contacts 805 is located inside the sleeve socket 804, and the second electrical contacts 805 are electrically connected to the third socket 803. The second electrical contacts 805 face the red lens 2, so that during the rotation of the three sets of first electrical contacts 505 outside the power supply head 503, only one set of first electrical contacts 505 is connected to the second electrical contacts 805. By setting the first electrical contacts 505 and the second electrical contacts 805 to supply power, the triangular mounting bracket 5 can connect to the car data interface through the power supply module 8 during rotation. The second electrical contacts 805 always face the red lens 2, so only the lamp bead assembly 6 facing the red lens 2 will be in working state.

[0037] Please refer to the above embodiments for further details. Figure 9 The drive mechanism 7 includes a cover 701, and a drive device 702 is provided inside the cover 701. The drive device 702 and the triangular prism 501 are connected by a gear set 703 and a worm gear assembly 704. The drive mechanism 7 is used to drive the triangular mounting bracket 5 to rotate, so that the user can actively control the drive mechanism 7 to switch between different LED bead assemblies 6.

[0038] Please refer to the above embodiments for further details. Figure 4The side of the housing 801 is provided with a second socket 802. A wire harness is connected between the second socket 802 and the drive mechanism 7. The inner side of the inner mounting housing 4 is provided with a wire harness groove 9 for the wire harness. By providing the second socket 802, the drive mechanism 7 can be connected to the power supply module 8 through the wire harness. The power supply module 8 is connected to the car computer so that the user can control the drive mechanism 7 of the high-mounted brake light assembly. The wire harness groove 9 can lock the wire harness and reduce the shaking of the wire harness.

[0039] In practical operation, the multiple sets of LED components 6 in the high-mounted brake light assembly of this application can be switched automatically by setting the vehicle's on-board computer, or an electronic switching button can be set in the vehicle, allowing the user to independently select and control the switching of different LED components 6. The focusing lens 603 of different LED components 6 can be set with different light transmission forms, such as multiple "heart" structure light transmission modes or multiple "lightning bolt" structure light transmission modes. For this personalized brake light display effect, an electronic switching button can be used for operation. The switching method is achieved by actively controlling the operation of the drive mechanism 7 through a program written in the vehicle's on-board computer to achieve the purpose of switching the triangular mounting bracket 5.

[0040] Firstly, during installation, the high-mounted brake light assembly in this application is connected to the vehicle's data interface and the third connector 803. Then, the assembly is connected to the vehicle via the mounting bracket 3. The specific installation method varies depending on the vehicle model.

[0041] When the user presses the brake light, the electrical signal is connected to the third connector 803 through the car's data interface. Then, the third connector 803 is connected to the corresponding first connector 505 through the second connector 805. The corresponding first connector 505 is connected to the corresponding LED assembly 602 through the first connector 504. At this time, the LEDs facing the surface of the lamp panel 601 of the red lens 2 receive the electrical signal and emit light. The light is focused by the focusing lens 603 and then scattered outward through the red lens 2.

[0042] When the user selectively switches between different LED components 6, or when an LED component 6 is damaged and needs to be switched, such as through the electronic buttons on the car screen, or by the electronic signal for switching being connected to the drive mechanism 7 via the second connector 802 of the power supply module 8, the drive device 702 within the drive mechanism 7 is activated. This drives the triangular prism 501 to rotate 120° for adjustment via the gear set 703 and the worm gear assembly 704. In other words, switching to another LED component 6, the first contact piece 505 electrically connected to this LED component 6 also rotates at the same angle to connect with the second contact piece 805. In other words, only the LED component 6 facing the red lens 2 completes the circuit connection with the car. When the LED component 6 is in working condition and is frequently lit, the heat generated by its lamp plate 601 is transferred to the body of the triangular prism 501 and to the internal space of the triangular prism 501. The heat received by the triangular prism 501 is exchanged outward through its outer wall and transferred to its internal space. The heat accumulated in the internal space is then discharged outward through multiple sets of heat dissipation holes 502.

[0043] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the invention and are not intended to limit it. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the invention, but such modifications, substitutions, and variations are protected by patent law as long as they are within the scope of the claims of the present invention.
