DETAILED DESCRIPTION

[0043] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the application. However, the application can be practiced without the specific details. In other instances, well-known methods, procedures, components, and circuits have not been described in detail since such can be readily understood.

[0044] In the description of the present application, it should be understood that the terms "upper", "lower", "left", "right", and the like refer to the orientation or positional relationship shown in the drawings, and are only for the purpose of facilitating the description of the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0045] In addition, the terms "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined as "first", "second" can explicitly or implicitly include at least one of the features. In the description of the present application, the meaning of "a plurality of" is at least two, such as two, three, etc., unless otherwise specifically limited.

[0046] In the related art, the light-emitting logo assembly structure provided on the steering wheel is relatively complex, and the light-emitting logo assembly is relatively heavy. In addition, the existing light-emitting logo assembly needs to be used in cooperation with other hardening layers, and its performance is unstable.

[0047] Therefore, the present application provides a light-emitting logo installed on a steering wheel, which comprises a cover, a light-emitting logo assembly and a positioning connection structure. The cover is connected to the airbag of the steering wheel, and the inner end face of the cover has a mounting position for mounting the light-emitting logo assembly. The positioning connection structure is arranged on the cover and the light-emitting logo assembly, and the light-emitting logo assembly is mounted on the mounting position of the cover through the positioning connection structure. The light-emitting logo assembly comprises an accommodating cover body, a light-emitting assembly and a logo assembly, wherein the light-emitting assembly is arranged inside the accommodating cover body, the logo assembly is arranged outside the accommodating cover body, and the outer end face of the cover presents a flat structure after the logo assembly is mounted on the mounting position. The light-emitting assembly emits bright light to the logo assembly to make the logo assembly bright.

[0048] It can be understood that the light-emitting assembly is arranged inside the accommodating cover body, so that the air bag of the inner end surface of the cover does not directly contact the light-emitting assembly, thereby improving the stability of the light-emitting assembly while not affecting the point explosion effect when the safety air bag is point exploded. Moreover, the light-emitting assembly is arranged inside the accommodating cover body, so that the structure of the light-emitting emblem assembly is more modularized, thereby reducing the dispersion degree of each structure, i.e., reducing the complexity of the structure of the light-emitting emblem assembly. In addition, the sign assembly is arranged outside the accommodating cover body, and after being mounted at the mounting position, the outer end surface of the cover presents a flat structure, which not only realizes reasonable application of the mounting structure, but also improves the aesthetic degree.

The second end surface of the PCB board is provided with an electronic control device (including an ECU, Electronic Control Unit), or the PCB board 43 is connected to an external electronic control device to obtain at least the color change and brightness change of the lamp beads 431 of the PCB board 43 provided by the electronic control device. The electronic control device is arranged in an external manner, which can reduce the thickness of the PCB board 43, and also can reduce the heat dissipation. The first end surface of the reflective film 44 is attached to the second end surface of the PCB board 43, and the second end surface of the reflective film 44 is in contact with the rear end cover 32. The reflective film 44 is used to reflect the light of the lamp beads 431 to improve the light-emitting intensity of the PCB board 43. It should be noted that the PCB board is provided with an external power supply. In addition, in an example, the electronic control device is arranged on the second end surface of the PCB board, and the reflective film 44 is not arranged on the second end surface of the PCB board. When the electronic control device is arranged on the second end surface of the PCB board, the external power supply can be connected through the wire.

[0061] In the embodiment, the diffusion film 41, the light guide plate 42, the PCB plate 43 and the reflection film 44 are overlapped in the connecting direction. In an example, the diffusion film 41, the light guide plate 42, the PCB plate 43 and the reflection film 44 have similar shapes, so that the diffusion film 41, the light guide plate 42, the PCB plate 43 and the reflection film 44 can be connected together in a pasting manner or an injection molding manner.
