Description

Technical Field

[0001] The utility model relates to a door handle, in particular to a door handle with a lamp group and good sealing effect. Background Art

[0002] Many car door handles are equipped with light groups to indicate success or failure when opening or closing the door. This light group installed on the door handle includes a light emitter and a light guide installed on a PCB circuit board, and is built into the door handle. Generally, after receiving a signal from the car controller, the PCB circuit board will light up the light emitter on the PCB circuit board and guide the light to the surface of the door handle through the light guide. At this time, part of the light group needs to be exposed on the outer surface of the door handle, and the PCB circuit board is also close to the car door handle, so the sealing of the light group is very important, especially the sealing between the PCB circuit board and the light guide. Utility Model Content

[0003] The utility model aims to provide a car door handle with a lamp group and good sealing effect.

[0004] According to one aspect of the utility model, a car door handle is provided, which includes a housing and a lamp assembly built in the housing. The lamp assembly includes a PCB circuit board, a light emitter arranged on the PCB circuit board, and a light guide, the light guide is arranged between the housing and the PCB circuit board, and the light guide includes a light guide part, a body, and a sealing ring.

[0005] Preferably, the light guide is arranged above the light emitting body, and is used for guiding and radiating the light emitted by the light emitting body to the outside of the housing of the door handle.

[0006] Preferably, one end of the light guide portion facing the light-emitting body is a light guide grid.

[0007] Preferably, the main body is in a hollow cylindrical shape, is arranged around the light-emitting body, and is installed between the housing and the PCB circuit board.

[0008] Preferably, the main body and the light guide portion are integrally formed.

[0009] Preferably, sealing is achieved between the PCB circuit board and the body through a sealing ring.

[0010] Preferably, an annular groove is provided on one side of the body adjacent to the PCB circuit board, and the sealing ring is provided in the annular groove.

[0011] Preferably, the height of the sealing ring is greater than the depth of the annular groove. Therefore, when the light guide is installed between the housing of the door handle and the PCB circuit board, the sealing ring will abut the surface of the PCB circuit board. At the same time, the PCB circuit board will also appropriately squeeze the sealing ring, thereby producing a better sealing effect.

[0012] Preferably, the light emitting body is an LED lamp.

[0013] The automobile door handle provided by the utility model has a good sealing effect between the PCB circuit board and the light guide body through the sealing ring arranged in the annular groove of the light guide body. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Hereinafter, embodiments of the vehicle lamp according to the present invention will be described with reference to the drawings.

[0024] See also Figure 1 As shown, the utility model discloses a car door handle 100, which includes a housing 20 and a lamp assembly 10. The car door handle 100 is generally installed on a car door, and when the door is opened or closed, the lamp assembly 10 exposed outside the car door handle 100 will light up to indicate an incorrect operation or error.

[0025] See also Figure 2 and Figure 3As shown, a PCB circuit board 12 is arranged in the housing 20, and the shape of the PCB circuit board 12 generally conforms to the shape of the automobile door handle 100. A light emitter 13 is arranged on the PCB circuit board 12. After the PCB circuit board 12 connected to the outside receives a signal such as turning on or off the light, the light emitter 13 on the PCB circuit board 12 will light up. At this time, the light guide 11 is arranged to cover the light emitter 13. At this time, the light emitter 13 can be an LED lamp.

[0026] Specifically, see Figure 4 and Figure 5 As shown, the light guide 11 includes a light guide portion 111, a body 112 and a sealing ring 113. The light guide portion 111 is provided at the top of the light guide 11. The light guide portion 111 after being installed with the housing 20 and the PCB circuit board 12 is exposed on the surface of the housing 20, and guides and radiates the light emitted by the light source 13 to the outside of the door handle. The light guide 11 is also provided with a body 112, which is a hollow cylindrical shape, arranged around the light source 13, and is integrally formed with the light guide portion 111. An annular groove 114 is provided on one side of the body 112 adjacent to the PCB circuit board 12, and the sealing ring 113 is installed in the annular groove 114. At this time, the height of the sealing ring 113 is slightly higher than the depth of the annular groove 114, so one end of the sealing ring 113 will be exposed to the outside of the body 112.

[0027] See also Figure 6 When the seal ring 113 is installed together with the PCB circuit board 12, the part of the seal ring 113 exposed to the outside will abut against the PCB circuit board 12, and the PCB circuit board 12 will squeeze the seal ring 113, thereby achieving a sealing effect. At the same time, the side of the light guide 11 facing the light emitting body 13 is a light guide grid 116. This structure is more conducive to guiding and diverging the light emitted by the light emitting body 13.

[0028] Further, see Figure 7 As shown, a protruding rib 115 is provided in the annular groove 114 for clamping and fixing the sealing ring 113 .

[0029] It will be apparent to those skilled in the art that various modifications and variations can be made to the above exemplary embodiments of the present invention without departing from the spirit and scope of the present invention. Therefore, it is intended that the present invention covers modifications and variations of the present invention that fall within the scope of the appended claims and their equivalent technical solutions.
