Therefore, they should not be understood as limitations on this application.

[0053] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of such features. Throughout the description of this application, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0054] In the prior art, the luminous car logo assembly installed on the steering wheel is relatively complex in structure and heavy, which affects the effectiveness of airbag deployment. In addition, the performance of the existing luminous car logo assembly is unstable because it needs to be used in conjunction with other hardened layers.

[0055] Based on this, the present application provides a luminous car logo, which is installed on the steering wheel, including: a mounting cover, a car logo assembly, a luminous positioning element and a positioning connection structure; wherein the mounting cover is connected to the airbag of the steering wheel, and the outer end surface of the mounting cover has a mounting position for accommodating the car logo assembly and the luminous positioning element. The car logo assembly is installed at the mounting position of the mounting cover through the positioning connection structure. The car logo assembly includes a transparent layer, an IML diaphragm layer, a connecting support layer and a car logo, and a first injection molding structure corresponding to each other is provided between the transparent layer and the IML diaphragm layer, and the transparent layer and the IML diaphragm layer are connected by the first injection molding structure. A second injection molding structure corresponding to each other is provided between the IML diaphragm layer and the connecting support layer, and the IML diaphragm layer and the connecting support layer are connected by the second injection molding structure, and the IML diaphragm layer is located between the transparent layer and the connecting support layer. The car logo is presented on the transparent layer. The luminous positioning element is arranged at the installation position of the installation cover, and is close to the side of the inner end surface facing away from the installation cover, and is arranged opposite to the vehicle logo assembly through the positioning connection structure. The luminous positioning element can emit bright light to the vehicle logo assembly to make the vehicle logo illuminate; after the vehicle logo assembly and the luminous positioning element are respectively installed at the installation positions of the installation cover, the outer end surface of the installation cover can present a flat structure.

[0056] It can be understood that the luminous vehicle logo provided by the present application arranges the vehicle logo assembly and the luminous positioning element on the outer end face of the mounting cover, so that the airbag on the inner end face of the mounting cover does not directly contact the vehicle logo assembly and the luminous positioning element, and thus will not affect the detonation effect when the airbag is detonated. Moreover, arranging the luminous positioning element on the outer end face of the mounting cover can also enable the luminous positioning element to effectively dissipate heat. In addition, corresponding injection molding structures are provided between the transparent layer, the IML diaphragm layer, and the connecting support layer, so that the connection between the transparent layer, the IML diaphragm layer, and the connecting support layer is more stable, thereby improving the stability of the luminous vehicle logo. In addition, the vehicle logo assembly and the luminous positioning element can be installed on the mounting cover only by the positioning connection structure, and the outer end face of the mounting cover after installation presents a flat structure, which not only simplifies the mounting connection structure, but also improves the aesthetics.

[0057] Next, the luminous vehicle logo provided in this application will be described in detail with reference to the accompanying drawings.

[0058] First embodiment

[0059] The present application provides a luminous vehicle logo installed on a steering wheel, comprising: a mounting cover 1, a vehicle logo assembly 2, a luminous positioning element 5 and a positioning connection structure 6.

[0060] Specifically, in this embodiment, the mounting cover 1 is part of the steering wheel and is connected to the steering wheel's airbag. Specifically, the airbag is positioned on the inner end surface 12 of the mounting cover 1. At one angle, the mounting cover 1 has a roughly bow-shaped or U-shaped configuration. The outer end surface 11 of the mounting cover 1 defines a mounting location for the vehicle logo assembly 2 and the illuminated positioning element 5. This location is located in the middle of the outer end surface 11 of the mounting cover 1.

[0061] The vehicle logo assembly 2 is installed at the installation position of the installation cover 1 through the positioning connection structure 6. The vehicle logo assembly 2 includes a transparent layer 21, an IML diaphragm layer 22, a connecting support layer 23 and a vehicle logo 24, and the transparent layer 21, the IML diaphragm layer 22 and the connecting support layer 23 are integrally formed after injection molding. A first injection molding structure corresponding to each other is provided between the transparent layer 21 and the IML diaphragm layer 22, and the transparent layer 21 and the IML diaphragm layer 22 are connected by the first injection molding structure. In this embodiment, the first injection molding structure refers to the morphological structure required for the transparent layer 21 and the IML diaphragm layer 22 during injection molding. The first injection molding structure corresponding to each other is provided between the transparent layer 21 and the IML diaphragm layer 22 so that the transparent layer 21 and the IML diaphragm layer 22 can be quickly injected. Specifically, in one example, a first injection molding structure is provided on the first end surfaces of the transparent layer 21 and the IML diaphragm layer 22, respectively. The first injection molding structure includes a first accommodating cavity surface 31 and a first embedded surface structure 32. The first accommodating cavity surface 31 refers to a structure having a mold cavity structure but only one end surface. The first accommodating cavity surface 31 is provided on the first end surface of the transparent layer 21, and the first embedded surface structure 32 is provided on the first end surface of the IML diaphragm layer 22. The first embedded surface structure 32 is attached to the first accommodating cavity surface 31 to achieve an injection molding connection between the transparent layer 21 and the IML diaphragm layer 22. The transparent layer 21 has a glass-like transparent texture. The material of the transparent layer 21 is acrylic or transparent PC (Polycarbonate). This transparent material can give the transparent layer a glass-like transparent texture.

[0062] The IML diaphragm layer 22 is located between the transparent layer 21 and the connecting support layer 23. A second injection molding structure corresponding to each other is provided between the IML diaphragm layer 22 and the connecting support layer 23. The IML diaphragm layer 22 and the connecting support layer 23 are connected by the second injection molding structure. In this embodiment, the second injection molding structure refers to the morphological structure required for the IML diaphragm layer 22 and the connecting support layer 23 during injection molding. The second injection molding structure corresponding to each other is provided between the IML diaphragm layer 22 and the connecting support layer 23 so that the IML diaphragm layer 22 and the connecting support layer 23 can be quickly injection molded. Specifically, in one example, the second injection molding structure is provided on the second end faces of the IML diaphragm layer 22 and the connecting support layer 23, respectively. The second injection molding structure includes a second accommodating cavity surface 41 and a second embedded surface structure 42, wherein the second accommodating cavity surface 41 refers to a structure having a cavity structure but only having an end face on one side. A second accommodating cavity surface 41 is provided on the second end surface of the connecting support layer 23, and a second embedded surface structure 42 is provided on the second end surface of the IML diaphragm layer 22. The second embedded surface structure 42 is attached to the second accommodating cavity surface 41 to achieve a connection between the IML diaphragm layer 22 and the connecting support layer 23. The connecting support layer 23 is opaque and is made of polyethylene terephthalate (PET).

[0063] Furthermore, in one example, the transparent layer 21, the IML film layer 22, and the connecting support layer 23 are each rectangular, with the center of the rectangle forming an inclined surface relative to the end surfaces on both sides. Of course, in other examples, the transparent layer 21, the IML film layer 22, and the connecting support layer 23 can also be other injection-molded shapes.

[0064] When the transparent layer 21, the IML film layer 22, and the connecting support layer 23 are each rectangular, and the end surfaces on opposite sides of the middle of the rectangle form inclined surfaces, the first accommodating cavity surface 31 correspondingly includes a first accommodating surface 311 and a first limiting connecting surface 312, and the second accommodating cavity surface 41 correspondingly includes a second accommodating surface 411 and a second limiting connecting surface 412. The first accommodating surface 311 and the second accommodating surface 411 are opposed to each other in a first direction, and the accommodating morphological structures of the first accommodating surface 311 and the second accommodating surface 411 are adapted to each other. The adaptation of the accommodating morphological structures of the first accommodating surface 311 and the second accommodating surface 411 means that the morphological structures of the first accommodating surface 311 and the second accommodating surface 411 can be attached to or connected to each other. The first direction refers to the direction in which the transparent layer 21, the IML film layer 22, and the connecting support layer 23 are sequentially connected. The IML film layer 22 is disposed between the first accommodating surface 311 and the second accommodating surface 411. The first limiting connection surfaces 312 are disposed on opposite sides of the first accommodating surface 311 in the second direction, and the first limiting connection surfaces 312 have a first limiting connection angle 313 relative to the first accommodating surface 311. Correspondingly, the second limiting connection surfaces 412 are disposed on opposite sides of the second accommodating surface 411 in the second direction, and the second limiting connection surfaces 412 have a second limiting connection angle relative to the second accommodating surface 411. The first limiting connection surfaces 312 and the second limiting connection surfaces 412 are adapted and connected to achieve sequential connection of the transparent layer 21, the IML film layer 22, and the connection support layer 23. The first direction and the second direction are perpendicular to each other.

[0065] It should be noted that, in this embodiment, the first limiting connection surface 312 and the second limiting connection surface 412, in addition to being the injection molding shape, also have a certain limiting connection function, thereby making the transparent layer 21, the IML membrane layer 22, and the connection support layer 23 more stable during injection molding. Moreover, most importantly, the first limiting connection angle 313 and the second limiting connection angle respectively make the first limiting connection surface 312 and the second limiting connection surface 412 curved. This structural morphology can prevent the transparent layer 21, the IML membrane layer 22, and the connection support layer 23 from being observed as a layered structure. That is, although the transparent layer 21, the IML membrane layer 22, and the connection support layer 23 are a multi-layer structure, after injection molding through this morphological structure, only the entire vehicle logo assembly 2 composed of the transparent layer 21, the IML membrane layer 22, and the connection support layer 23 can be seen from this direction.

[0066] In one example, the first position-limiting connection angle 313 and the second position-limiting connection angle are preferentially set at the first position-limiting connection surface 312 on one side.

[0067] In this embodiment, the car logo 24 is presented on the transparent layer 21, and the transparent layer 21 has a glass-like transparent texture. Specifically, in one example, the car logo 24 is provided on the IML film layer 22. The specific style of the car logo 24 is set according to actual needs and is not specifically limited here. The car logo assembly 2 also includes a car logo decorative hole 25, and the car logo decorative hole 25 is provided on the connecting support layer 23, and the main body of the connecting support layer 23 is opaque. The car logo decorative hole 25 is opposite to and adapted to the car logo 24, and the car logo 24 is presented on the transparent layer 21 through the transparent layer 21. Among them, the car logo decorative hole 25 is adapted to the car logo 24, which means that the shape and size of the car logo decorative hole 25 are the same as the shape and size of the outer contour of the car logo 24, so that the car logo decorative hole 25 and the car logo 24 can overlap in one direction.

[0068] In this embodiment, the vehicle logo assembly 2 is installed at the installation position of the installation cover 1 through the positioning connection structure 6. In one example, the positioning connection structure 6 is arranged between the first end surface of the connection support layer 23 and the installation position of the installation cover 1, and the positioning connection structure 6 includes: a welding column 61, a first installation groove 62, a connection card hole 63, a positioning pin 66 and a positioning hole 67. In one example, the welding column 61 is arranged at the first end surface of the connection support layer 23 and faces the installation cover 1. There are multiple welding columns 61, and the thickness of the welding columns 61 can be set to different. The positioning pin 66 is arranged at the first end surface of the connection support layer 23 and is located on the side of the welding column 61. In one example, there are two positioning pins 66, and they are respectively located on the side of the welding column 61, specifically on both sides of the first end surface of the connection support layer 23. In one example, there are four positioning pins 66, and every two positioning pins 66 are located on both sides of the first end surface of the connection support layer 23. The first mounting groove 62 is recessed in the outer end surface 11 of the mounting cover 1, and the first mounting groove 62 can serve as part of the mounting position of the mounting cover 1. In one example, corresponding to the rectangular shape of the connecting support layer 23, the groove shape of the first mounting groove 62 is set to a rectangle. The connecting card hole 63 is corresponding to the welding column 61 and is set through the bottom of the first mounting groove 62. The connecting card hole 63 passes through the bottom of the first mounting groove 62, which means that the connecting card hole 63 passes through the mounting cover 1, and specifically passes through the mounting position of the mounting cover 1. The orifice size of the connecting card hole 63 can be different, and it is plugged into the corresponding welding column 61. The positioning hole 67 is corresponding to the positioning pin 66 and is set through the bottom of the first mounting groove 62. The positioning hole 67 is positioned and connected with the positioning pin 66. After the welding column 61 is inserted into the connection card hole 63 , the column head of the welding column 61 is welded to the inner end surface 12 of the installation cover 1 to fix the connection support layer 23 to the installation position of the installation cover 1 .

[0069] The light-emitting positioning element 5 is arranged at the installation position of the installation cover 1, and is close to the side of the inner end surface 12 facing away from the installation cover 1, and is arranged opposite to the vehicle logo component 2 through the positioning connection structure 6. Specifically, the light-emitting positioning element 5 includes: a light guide plate 51, a PCB board 52, a power supply component 53 and a positioning connection hole 54. Among them, the positioning connection structure 6 also includes a second installation groove 64, which is recessed in the bottom of the first installation groove 62, and the second installation groove 64 is on the outer end surface 11 of the installation cover 1. The second installation groove 64 can be used as a part of the installation position of the installation cover 1, and the bottom of the second installation groove 64 is on the side facing away from the inner end surface 12 of the installation cover 1. The groove shape of the second installation groove 64 is adapted to the shape and size of the light guide plate 51. The light guide plate 51 is installed in the second installation groove 64. The PCB board 52 is relatively arranged on both sides of the light guide plate 51. The power supply component 53 is connected to the PCB board 52. In one example, the power supply assembly 53 includes a power connector and a power line, one end of the power line is connected to the PCB board 52, and the other end of the power line is connected to the power connector. The power connector is connected to the car's power connector. In one example, the bottom of the second mounting groove 64 is further provided with a threading hole 65, so that the power line of the power supply assembly 53 passes through the threading hole 65. The positioning connection hole 54 is provided at the bottom of the light guide plate 51 and the second mounting groove 64, wherein the positioning connection hole 54 provided at the bottom of the second mounting groove 64 passes through the bottom of the second mounting groove 64, and the positioning connection hole 54 passing through the bottom of the second mounting groove 64 means that the positioning connection hole 54 passes through the mounting cover 1, and specifically passes through the mounting position of the mounting cover 1.

[0075] Second embodiment

[0076] The embodiment of the present application provides a steering wheel airbag assembly, comprising an airbag and the aforementioned luminous vehicle logo, wherein the airbag is placed in the mounting cover 1. The luminous vehicle logo can be referred to the description of the above embodiment and will not be repeated here.

[0077] Third embodiment

[0078] The embodiment of the present application also provides a molding process for a luminous vehicle logo, such as Figure 9 As shown, Figure 9This is a flow chart of a molding process for a luminous vehicle logo provided in an embodiment of the present application. The molding process for the luminous vehicle logo includes the following steps:

[0079] Step S101 : In a first injection molding mold, an IML film layer with a vehicle logo is formed by IML process.

[0080] Specifically, a base film suitable for IML processing is selected. A logo bearing a vehicle logo is printed onto the base film using the IML process to form an initial IML film layer. This initial IML film layer is then placed in a first injection mold. Temperature and pressure are used to shape the initial IML film layer with the logo to the desired shape. The shaped initial IML film layer is then trimmed to form an IML film layer bearing the vehicle logo and possessing a morphological structure. The first injection mold is used to shape the initial IML film layer. In this embodiment, the IML process involves printing ink on the inner surface of a polymer film, hot-pressing the printed film into the 3D shape of the product, then cutting and trimming the outer shape and inner hole. The film is then placed into an injection mold cavity, and a molding resin is injected into the metal mold, where it is bonded to the film and solidified to form the product. This method achieves aesthetically pleasing surface patterns and superior performance while maintaining the structure and performance of the plastic part.

[0081] Step S102 : in a second injection molding mold, a transparent material is processed to form a transparent layer, and the IML film layer and the transparent layer are injection molded for the first time to adhere the IML film layer to the transparent layer to form a composite layer.

[0082] Specifically, in this step, a transparent material is placed in a second injection mold to shape the transparent material, and the shaping structure of the transparent material is adapted to the structure of the IML diaphragm layer. The transparent material is acrylic or transparent PC (Polycarbonate). The transparent material can give the transparent layer a glassy, ​​transparent texture. The second injection mold is used to injection mold the transparent material. After the transparent material is shaped into a transparent layer in the second injection mold, the IML diaphragm layer is placed in the second injection mold, and the IML diaphragm layer is placed in a position adapted to the transparent layer. The IML diaphragm layer and the transparent layer are injection molded for the first time using the second injection mold to adhere the IML diaphragm layer to the transparent layer to form a composite layer.

[0083] Step S103, in a third injection mold, a non-transparent material is used for processing to form a connecting support layer, and the composite layer and the connecting support layer are injection molded for a second time to form a vehicle logo assembly; the first end face of the connecting support layer can be injection molded with a partial positioning connection structure.

[0084] Specifically, a non-transparent material is placed in a third injection mold to shape the non-transparent material, and the shaping structure of the non-transparent material is adapted to the structure of the IML diaphragm layer and the transparent layer. Wherein, the non-transparent material refers to PET (Polyethylene terephthalate) material. Specifically, when the non-transparent material is shaped to form a connecting support layer, the shaping structure of the second end face of the connecting support layer is adapted to the structure of the IML diaphragm layer and the transparent layer. The first end face of the connecting support layer can be injection molded with a partial positioning connection structure, and the partial positioning connection structure is specifically an integrally formed positioning connection protrusion and a reverse limit hook, or a welding column. Injection molding the first end face of the connecting support layer with a partial positioning connection structure can improve the stability of the connecting support layer connected to the installation position of the installation cover through the positioning connection structure. Wherein, the third injection mold is used to injection mold the non-transparent material. After the non-transparent material is shaped in the third injection mold to form the connecting support layer, the composite layer formed by injection molding the IML membrane layer and the transparent layer is placed in the third injection mold, and the composite layer formed by injection molding the IML membrane layer and the transparent layer is positioned to match the second end surface of the connecting support layer. A second injection molding is performed on the composite layer formed by injection molding the IML membrane layer and the transparent layer and the connecting support layer in the third injection mold to form the vehicle logo assembly.

[0085] The molding process for the luminous vehicle logo provided in the embodiments of the present application utilizes different injection molds to form the transparent layer, IML film layer, and connecting support layer, respectively, enabling precise and efficient injection molding of each layer. Furthermore, each layer is linked in processing: the second injection mold can perform the first injection molding of the IML film layer and the transparent layer, while the third injection mold can perform the second injection molding of the composite layer formed by the IML film layer and the transparent layer and the connecting support layer, thereby forming the vehicle logo assembly. This improves both processing accuracy and efficiency.
