Description
Technical Field
[0001] This utility model relates to the technical field of side turn signals, and in particular to an LED side turn signal for automobiles. Background Technology
[0002] Side turn signals on a car are lights mounted on the sides of the vehicle to indicate the direction of turn. They are typically located at the front and rear of the car, on the left and right sides respectively, to alert other road users to the vehicle's direction of travel.
[0003] Existing automotive side turn signals consist of components such as a housing, a reflector, a wire, a light source, and a lamp cover. The reflector is located between the housing and the lamp cover, and the housing has a cavity for accommodating the reflector. After prolonged use, it has been found that the reflector located between the housing and the lamp cover is prone to displacement, which to some extent affects the service life of the side turn signal. Utility Model Content
[0004] To ensure the service life of the automotive LED side turn signal, this application provides an automotive LED side turn signal.
[0005] This application provides an LED side turn signal for automobiles, which adopts the following technical solution:
[0006] An LED side turn signal for automobiles includes a housing and a reflector and a lamp cover disposed on the housing. The reflector is located between the housing and the lamp cover. The housing is provided with a plurality of LED components. Each LED component includes a circuit board and LED light patches attached to the circuit board. The housing is provided with a mounting part corresponding to the LED component. The mounting part is provided with a mounting groove for fitting the circuit board. A light-transmitting hole is provided through the reflector. The reflector protrudes towards the housing to form a light-transmitting cavity for accommodating the LED component. The light-transmitting hole communicates with the light-transmitting cavity. The end of the circuit board away from the housing extends into the light-transmitting cavity.
[0007] The portion of the housing corresponding to the reflector protrudes in a direction away from the reflector to form a receiving cavity for accommodating the reflector. The reflector is provided with a limiting block, and the housing is provided with a limiting groove for the limiting block to fit into. The limiting groove is in communication with the receiving cavity.
[0008] By adopting the above technical solution, LED lights, compared with traditional bulbs, have better penetration and response speed, as well as a longer service life, thus ensuring the service life of the side turn signal to a certain extent. Through the setting of the receiving cavity, the reflector is less likely to move relative to the housing during the process of fixing the reflector and the housing. The cooperation of the limiting block and the limiting groove can provide positioning for fixing the reflector and the housing, further limiting the movement of the reflector relative to the housing, and improving the service life of the side turn signal.
[0009] Preferably, the housing is further provided with a positioning block, which is arranged along the edge of the receiving cavity, and the side of the positioning block opposite to the receiving cavity is in contact with the inner wall of the lampshade.
[0010] By adopting the above technical solution, the positioning block can provide positioning for the installation of the lampshade, thereby improving the efficiency of lampshade installation.
[0011] Preferably, the housing has a through-hole for ventilation, and the housing is provided with a breathable membrane for sealing the ventilation hole.
[0012] By adopting the above technical solution, the heat generated during the operation of the side turn signal can be discharged through the vent holes, thereby maintaining the normal operating temperature of the side turn signal and extending its service life. The vent membrane can prevent moisture from entering the side turn signal while maintaining good ventilation, thus protecting the normal use of the side turn signal and extending its service life to a certain extent.
[0013] Preferably, the housing and the reflector are fixed together by connecting bolts, the reflector is provided with a connecting post on the side facing the housing, the connecting post is provided with a threaded hole coaxially with the connecting bolt, and the housing is provided with a through hole for the connecting bolt to pass through.
[0014] By adopting the above technical solution, the housing and reflector are fixed by connecting bolts. The housing and reflector are detachably connected, which facilitates the later inspection and maintenance of the turn signal on this side.
[0015] Preferably, the housing is provided with multiple first support protrusions that are attached to the circuit board, and the reflector is provided with multiple second support protrusions that are attached to the circuit board. The multiple first support protrusions are spaced apart, and the multiple second support protrusions are spaced apart.
[0016] By adopting the above technical solution, the spacing between adjacent first support protrusions and adjacent second support protrusions creates a gap for ventilation between the circuit board, the housing, and the reflector, which can protect the normal use of the side turn signal.
[0017] Preferably, the lampshade has multiple raised ridges inside.
[0018] By adopting the above technical solution, the convex ridge allows light to be refracted multiple times in the lamp cover and then scattered in multiple directions, which can ensure the uniform distribution of light and improve the safety of side turn signals during use.
[0019] Preferably, the circuit boards in two adjacent LED assemblies are connected by wires, and the housing is provided with a wire management plate, which has a wire management groove for power supply wire insertion.
[0020] By adopting the above technical solution, the wires located inside the turn signal can be fixed by the cable management plate and cable management channel, making them less likely to get tangled or shift.
[0021] Preferably, the size of the light-transmitting cavity increases sequentially in the direction away from the housing.
[0022] By adopting the above technical solution, the illumination range of the side turn signal can be effectively expanded, ensuring that vehicles in adjacent lanes and blind spots of the rearview mirror can clearly identify the turn signal, thus effectively improving the safety of using the side turn signal.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] 1. By setting up the receiving cavity, the reflector is less likely to move relative to the housing during the process of fixing the reflector and the housing. The cooperation between the limiting block and the limiting groove can provide positioning for fixing the reflector and the housing, further limiting the movement of the reflector relative to the housing, and improving the service life of the side turn signal.
[0025] 2. The design of the vent holes and vent membrane can ensure the ventilation performance of the side turn lights while preventing moisture from entering the interior of the side turn lights, thus extending the service life of the side turn lights to a certain extent.

[0030] The following is in conjunction with the appendix Figure 1-3 The present invention will be described in further detail below.
[0031] This application discloses an LED side turn signal for automobiles, see embodiment. Figure 1 and Figure 2 The device includes a housing 1 and a reflector 2 and a lampshade 3 disposed on the housing 1. In this embodiment, the housing 1, reflector 2 and lampshade 3 are all made of plastic. The reflector 2 is located between the housing 1 and the lampshade 3. The housing 1 is provided with multiple LED components 4. The number of LED components 4 depends on the actual vehicle light. The automotive LED side turn signal in this embodiment includes three LED components 4. Compared with traditional bulbs, LED lights have better penetration and response speed, as well as a longer service life, which can ensure the service life of the side turn signal to a certain extent.
[0032] Reference Figure 2 and Figure 3 The LED component 4 includes a circuit board 41 and an LED patch 42 attached to the circuit board 41. The housing 1 has an integrally formed mounting part 11 corresponding to the LED component 4. The mounting part 11 has a mounting groove 111 for the circuit board 41 to fit into. The circuit board 41 is fixed to the mounting part 11 by bolts, which ensures the stability of the circuit board 41 fixed to the housing 1. The reflector 2 has a light-transmitting hole 22 through it. The reflector 2 also protrudes towards the housing 1 to form a light-transmitting cavity 21 for accommodating the LED component 4. The light-transmitting hole 22 communicates with the light-transmitting cavity 21. The end of the circuit board 41 away from the housing 1 extends into the light-transmitting cavity 21, and the LED patch 42 is located in the light-transmitting cavity 21. The reflector 2 is coated with a silver coating. The silver coating can improve the reflection efficiency of the inner wall of the light-transmitting cavity 21, making the side turn light light more concentrated and brighter. This design can ensure that the light of the side turn light still has stronger penetration in low visibility environments such as rain, fog, and night, and improve the safety during driving.
[0033] Reference Figure 2 and Figure 3 The size of the light-transmitting cavity 21 increases sequentially in the direction away from the housing 1. That is, the light-transmitting cavity 21 is similar to a frustum, but it is not necessarily a standard frustum. The tilt angle of the inner wall of the light-transmitting cavity 21 can be adjusted according to actual use needs. This design can effectively expand the illumination range of the side turn signal, ensuring that vehicles in adjacent lanes and blind spots of the rearview mirror can clearly identify the turn signal, effectively improving the safety of using the side turn signal.
[0034] Reference Figure 2 and Figure 3The circuit boards 41 of two adjacent LED components 4 are connected by wires 43. A wire management plate 12 is integrally formed on the housing 1. The wire management plate 12 is provided with a wire management groove 121 for the power supply wire 43 to be inserted. Through the arrangement of the wire management plate 12 and the wire management groove 121, the wire 43 located in the side turn signal can be fixed, so that it is not easy to get tangled or shift. The opening of the wire management groove 121 decreases sequentially along the direction towards the housing 1, so that the wire 43 can be moved to be embedded in the wire management groove 121.
[0035] Reference Figure 2 The housing 1 has a through-hole 13. The heat generated during the operation of the side turn signal can be discharged through the through-hole 13, thereby maintaining the normal operating temperature of the side turn signal and extending its service life. In addition, the housing 1 is also provided with a breathable membrane 131 for sealing the through-hole 13. The breathable membrane 131 can prevent moisture from entering the side turn signal while maintaining good air permeability, thereby protecting the normal use of the side turn signal and extending its service life to a certain extent.
[0036] Reference Figure 2 and Figure 3 The housing 1 has multiple first support protrusions 14 integrally formed on it, which are attached to the circuit board 41. The reflector 2 has multiple second support protrusions 23 integrally formed on it, which are attached to the circuit board 41. In this embodiment, each circuit board 41 corresponds to two first support protrusions 14 and two second support protrusions 23. The two first support protrusions 14 are spaced apart, and the two second support protrusions 23 are also spaced apart, so that there is a gap for ventilation between the circuit board 41 and the housing 1 and the reflector 2, which can protect the normal use of the side turn signal.
[0037] Reference Figure 2 and Figure 3 The portion of the housing 1 corresponding to the reflector 2 protrudes in a direction away from the reflector 2 to form a receiving cavity 15 for accommodating the reflector 2. The setting of the receiving cavity 15 makes it difficult for the reflector 2 to move relative to the housing 1 during the process of fixing the reflector 2 to the housing 1, thereby improving the reliability of fixing the reflector 2 to the housing 1. A limiting block 24 is integrally formed on the reflector 2, and the housing 1 is provided with a limiting groove 241 for the limiting block 24 to fit into. The limiting groove 241 communicates with the receiving cavity 15. With the cooperation of the limiting block 24 and the limiting groove 241, it is further difficult for the reflector 2 to move relative to the housing 1, and it provides positioning during the process of fixing the reflector 2 to the housing 1.
[0038] Reference Figure 2A positioning block 16 is integrally formed on the housing 1. The positioning block 16 is set along the edge of the receiving cavity 15. The side of the positioning block 16 opposite to the receiving cavity 15 is attached to the inner wall of the lamp cover 3. The positioning block 16 can provide positioning for the installation of the lamp cover 3, improving the installation efficiency of the lamp cover 3. The lamp cover 3 can be fixed to the housing 1 by adhesive. The lamp cover 3 has multiple protruding ribs 31 inside. The protruding ribs 31 allow light to be refracted multiple times in the lamp cover 3, and then scattered in multiple directions. This can ensure uniform light distribution and improve the safety of the side turn signal during use.
[0039] Reference Figure 2 and Figure 3 The housing 1 and the reflector 2 are fixed together by connecting bolts. The reflector 2 has an integrally formed connecting post 25 on the side facing the housing 1. The connecting post 25 is coaxially provided with a threaded hole 251 that mates with the connecting bolt. The housing 1 has a through hole 17 for the connecting bolt to pass through. The housing 1 and the reflector 2 are fixed together by connecting bolts. The housing 1 and the reflector 2 are detachably connected, which facilitates the later inspection and maintenance of the turn signal on this side.
[0040] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
