Detailed Implementation

[0051] Many specific details are set forth in the following description to provide a full understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of this application; therefore, this application is not limited to the specific embodiments disclosed below.

[0052] In the description of this application, it should be understood that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of 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 technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0054] In related technologies, the structure of the illuminated car emblem component on the steering wheel is relatively complex, and the component is also quite heavy. This can affect the deployment effectiveness of the airbag. Furthermore, existing illuminated car emblem components require the use of other hardened layers, resulting in unstable performance.

[0055] This application provides a luminous car emblem, mounted on a steering wheel, comprising: a mounting cover, an emblem 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 face of the mounting cover has a mounting position for accommodating the emblem assembly and the luminous positioning element. The emblem assembly is mounted on the mounting position of the mounting cover via the positioning connection structure. The emblem assembly includes a transparent layer, an IML film layer, a connecting support layer, and an emblem, and a first injection molding structure corresponding to each other is provided between the transparent layer and the IML film layer, and the transparent layer and the IML film layer are connected through the first injection molding structure. A second injection molding structure corresponding to each other is provided between the IML film layer and the connecting support layer, and the IML film layer and the connecting support layer are connected through the second injection molding structure, with the IML film layer located between the transparent layer and the connecting support layer. The emblem is displayed on the transparent layer. The luminous positioning element is located at the mounting position of the mounting cover and close to the side facing away from the inner end face of the mounting cover. It is positioned opposite to the car logo component through a positioning connection structure. The luminous positioning element can emit light to the car logo component to make the car logo light up. After the car logo component and the luminous positioning element are installed at the mounting position of the mounting cover, the outer end face of the mounting cover can present a flat structure.

[0056] This application provides an luminous car emblem where the emblem component and luminous positioning element are positioned on the outer end face of the mounting cover. This prevents the airbag on the inner end face of the mounting cover from directly contacting the emblem component and luminous positioning element, thus avoiding any impact on the airbag deployment effect. Furthermore, positioning the luminous positioning element on the outer end face of the mounting cover allows for effective heat dissipation. Additionally, corresponding injection molding structures are provided between the transparent layer, the IML film layer, and the connecting support layer, resulting in a more stable connection and improved stability of the luminous car emblem. Moreover, the emblem component and luminous positioning element can be mounted on the mounting cover using only the positioning connection structure, and the outer end face of the mounted cover after installation has a flat structure, simplifying the installation connection structure and improving aesthetics.

[0057] The luminous vehicle emblem provided in this application will now be described in detail with reference to the accompanying drawings.

[0058] First Embodiment

[0059] This application provides a light-emitting car emblem, which is installed on a steering wheel and includes: a mounting cover 1, an emblem assembly 2, a light-emitting 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 airbag of the steering wheel, i.e., the airbag is located on the inner end face 12 side of the mounting cover 1. At a certain angle, the mounting cover 1 is approximately bow-shaped or U-shaped. The outer end face 11 of the mounting cover 1 has a mounting position for accommodating the car emblem assembly 2 and the light-emitting positioning element 5. This mounting position is located in the middle of the outer end face 11 of the mounting cover 1.

[0061] The logo component 2 is installed at the mounting position of the mounting cover 1 via the positioning connection structure 6. The logo component 2 includes a transparent layer 21, an IML film layer 22, a connecting support layer 23, and a logo 24, and the transparent layer 21, IML film layer 22, and connecting support layer 23 are integrally molded after injection molding. A corresponding first injection molding structure is provided between the transparent layer 21 and the IML film layer 22, connecting them. In this embodiment, the first injection molding structure refers to the required shape structure of the transparent layer 21 and the IML film layer 22 during injection molding. The corresponding first injection molding structure between the transparent layer 21 and the IML film layer 22 allows for rapid injection molding of the two layers. Specifically, in one example, a first injection molding structure is disposed on the respective first end faces of the transparent layer 21 and the IML film layer 22. The first injection molding structure includes a first accommodating cavity surface 31 and a first faceting structure 32. The first accommodating cavity surface 31 refers to a structure with a cavity structure but only one end face. The first accommodating cavity surface 31 is disposed on the first end face of the transparent layer 21, and the first faceting structure 32 is disposed on the first end face of the IML film layer 22. The first faceting structure 32 is attached to the first accommodating cavity surface 31 to achieve injection molding connection between the transparent layer 21 and the IML film 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 allows the transparent layer to have a glass-like transparent texture.

[0062] The IML film layer 22 is located between the transparent layer 21 and the connecting support layer 23. A corresponding second injection molding structure is provided between the IML film layer 22 and the connecting support layer 23, connecting them via the second injection molding structure. In this embodiment, the second injection molding structure refers to the required shape structure of the IML film layer 22 and the connecting support layer 23 during injection molding. The corresponding second injection molding structure between the IML film layer 22 and the connecting support layer 23 allows for rapid injection molding. Specifically, in one example, the second injection molding structure is located on the respective second end faces of the IML film layer 22 and the connecting support layer 23. The second injection molding structure includes a second accommodating cavity surface 41 and a second insert structure 42. The second accommodating cavity surface 41 refers to a structure with a cavity structure but only one end face. The second accommodating cavity surface 41 is disposed on the second end face of the connecting support layer 23, and the second interfacing structure 42 is disposed on the second end face of the IML membrane layer 22. The second interfacing structure 42 is attached to the second accommodating cavity surface 41 to achieve the connection between the IML membrane layer 22 and the connecting support layer 23. The connecting support layer 23 is opaque, and the non-transparent material of the connecting support layer 23 is PET (Polyethylene terephthalate).

[0063] Furthermore, in one example, the transparent layer 21, the IML film layer 22, and the connecting support layer 23 are all rectangular, and the middle part of the rectangle forms an inclined surface relative to the two end faces. 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 forms.

[0064] When the transparent layer 21, the IML film layer 22, and the connecting support layer 23 are all rectangular, and the middle portion of each rectangle has an inclined end face relative to the two sides, the first receiving cavity surface 31 includes a first receiving surface 311 and a first limiting connection surface 312, and the second receiving cavity surface 41 includes a second receiving surface 411 and a second limiting connection surface 412. The first receiving surface 311 and the second receiving surface 411 are opposite each other in a first direction, and their receiving shapes and structures are compatible. This compatibility means that the shapes and structures of the first receiving surface 311 and the second receiving surface 411 can be fitted or interlocked. 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 receiving surface 311 and the second receiving surface 411. The first limiting connecting surface 312 is disposed on both sides of the first receiving surface 311 in the second direction, and the first limiting connecting surface 312 has a first limiting connecting angle 313 relative to the first receiving surface 311. Correspondingly, the second limiting connecting surface 412 is disposed on both sides of the second receiving surface 411 in the second direction, and the second limiting connecting surface 412 has a second limiting connecting angle relative to the second receiving surface 411. The first limiting connecting surface 312 and the second limiting connecting surface 412 are adapted and connected to realize the sequential connection of the transparent layer 21, the IML film layer 22 and the connecting 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 injection molding connection of the transparent layer 21, the IML film layer 22 and the connecting support layer 23 more stable. 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 shape can prevent the transparent layer 21, the IML film layer 22 and the connecting support layer 23 from being observed as a layered structure. That is, although the transparent layer 21, the IML film layer 22 and the connecting support layer 23 are multi-layered structures, after injection molding through this structure, only the entire car logo component 2 composed of the transparent layer 21, the IML film layer 22 and the connecting support layer 23 will be visible in this direction.

[0066] In one example, the first limiting connection angle 313 and the second limiting connection angle are preferably set on the first 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 disposed 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 component 2 also includes a car logo accessory hole 25, which is disposed on the connecting support layer 23, and the main body of the connecting support layer 23 is opaque. The car logo accessory 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. Wherein, the car logo accessory hole 25 and the car logo 24 are adapted to each other, meaning that the shape and size of the car logo accessory hole 25 are the same as the shape and size of the outer contour of the car logo 24, so that the car logo accessory hole 25 and the car logo 24 can overlap in one direction.

[0068] In this embodiment, the logo component 2 is installed on the mounting position of the mounting cover 1 via the positioning connection structure 6. In one example, the positioning connection structure 6 is disposed between the first end face of the connecting support layer 23 and the mounting position of the mounting cover 1. The positioning connection structure 6 includes: a welding post 61, a first mounting groove 62, a connecting slot 63, a positioning pin 66, and a positioning hole 67. The welding post 61 is located on the first end face of the connecting support layer 23 and faces the mounting cover 1. Multiple welding posts 61 are provided, and their thicknesses can be set to different values. The positioning pin 66 is located on the first end face of the connecting support layer 23 and is situated on the side of the welding post 61. In one example, two positioning pins 66 are provided, each located on one side of the welding post 61, specifically on both sides of the first end face of the connecting support layer 23. In another example, four positioning pins 66 are provided, with every two positioning pins 66 located on both sides of the first end face of the connecting support layer 23. The first mounting groove 62 is recessed on the outer end face 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 be rectangular. The connecting hole 63 is correspondingly provided with the welding post 61 and is provided through the bottom of the first mounting groove 62. The connecting hole 63 passing through the bottom of the first mounting groove 62 means that the connecting hole 63 passes through the mounting cover 1, and specifically, it passes through the mounting position of the mounting cover 1. The size of the opening of the connecting hole 63 can be different, and it is inserted into the corresponding welding post 61. The positioning hole 67 is correspondingly provided with the positioning pin 66 and is provided through the bottom of the first mounting groove 62. The positioning hole 67 and the positioning pin 66 are positioned and connected. After the welding post 61 is inserted into the connecting clip hole 63, the head of the welding post 61 is fused to the inner end face 12 of the mounting cover 1 to fix the connecting support layer 23 to the mounting position of the mounting cover 1.

[0069] The light-emitting positioning element 5 is located at the mounting position of the mounting cover 1, close to the side facing away from the inner end face 12 of the mounting cover 1, and is positioned opposite to the car logo component 2 via 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. The positioning connection structure 6 further includes a second mounting groove 64, which is recessed into the bottom of the first mounting groove 62 and is located on the outer end face 11 of the mounting cover 1. The second mounting groove 64 serves as part of the mounting position of the mounting cover 1, and the bottom of the second mounting groove 64 faces away from the inner end face 12 of the mounting cover 1. The groove shape of the second mounting groove 64 matches the shape and size of the light guide plate 51. The light guide plate 51 is installed in the second mounting groove 64. The PCB board 52 is positioned opposite to 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 component 53 includes a connector and a power transmission line. One end of the power transmission line is connected to the PCB board 52, and the other end is connected to the connector. The connector is connected to an automotive power connector. In one example, the bottom of the second mounting slot 64 is also provided with a through hole 65 so that the power transmission line of the power supply component 53 passes through the through hole 65. A positioning connection hole 54 is provided at the bottom of the light guide plate 51 and the second mounting slot 64. The positioning connection hole 54 at the bottom of the second mounting slot 64 penetrates the bottom of the second mounting slot 64, which means that the positioning connection hole 54 penetrates the mounting cover 1, specifically penetrating the installation position of the mounting cover 1. The positioning connection holes 54 correspond to the welding posts 61 and the connecting holes 63, respectively. Specifically, the positioning connection holes 54 correspond to a portion of the welding posts 61 and a portion of the connecting holes 63, which are within the projection range of the light guide plate 51. After the welding posts 61 are sequentially inserted into the connecting holes 63 and the positioning connection holes 54, the heads of the welding posts 61 are fused to the inner end face 12 of the mounting cover 1, thereby mounting the light-emitting positioning element 5 on the outer end face 11 of the mounting cover 1.

[0070] In one example, the positioning connection structure 6 can also be as follows: specifically, the positioning connection structure 6 is disposed between the first end face of the connecting support layer 23 and the mounting position of the mounting cover 1. The positioning connection structure 6 includes: a positioning connection protrusion, a reverse limiting hook, a first mounting groove 62, a connecting hole 63, a positioning pin 66, and a positioning hole 67. The positioning connection protrusion is located on the first end face of the connecting support layer 23 and faces the mounting cover 1.

The positioning pin 66 is located on the first end face of the connecting support layer 23 and is situated on the side of the positioning connection protrusion. In one example, two positioning pins 66 are provided, each located on the side of the positioning connection protrusion, specifically on both sides of the first end face of the connecting support layer 23. In another example, four positioning pins 66 are provided, with every two positioning pins 66 located on both sides of the first end face of the connecting support layer 23. The reverse limiting hook is integrally formed with the end of the positioning connection protrusion. The first mounting groove 62 is recessed on the outer end face 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 be rectangular. The connecting hole 63 is correspondingly provided with the positioning connecting protrusion and is provided through the bottom of the first mounting groove 62. The connecting hole 63 passing through the bottom of the first mounting groove 62 means that the connecting hole 63 passes through the mounting cover 1, and specifically, it passes through the mounting position of the mounting cover 1. The size of the opening of the connecting hole 63 can be different, and it is inserted into the corresponding positioning connecting protrusion. The positioning hole 67 is correspondingly provided with the positioning pin 66 and is provided through the bottom of the first mounting groove 62. The positioning hole 67 is positioned and connected with the positioning pin 66.

In one example, the bottom of the second mounting slot 64 is also provided with a through hole 65 so that the power transmission line of the power supply component 53 passes through the through hole 65. A positioning connection hole 54 is provided at the bottom of the light guide plate 51 and the second mounting slot 64. The positioning connection hole 54 at the bottom of the second mounting slot 64 penetrates the bottom of the second mounting slot 64, which means that the positioning connection hole 54 penetrates the mounting cover 1, specifically penetrating the installation position of the mounting cover 1. The positioning connection holes 54 correspond to the positioning connection protrusions and the connection locking holes 63, respectively. Specifically, the positioning connection holes 54 correspond to a portion of the positioning connection protrusions and a portion of the connection locking holes 63, which are within the projection range of the light guide plate 51. After the positioning connection protrusions are sequentially inserted into the connection locking holes 63 and the positioning connection holes 54, the reverse limiting hooks are engaged with the inner end face 12 of the mounting cover 1, thereby mounting the light-emitting positioning element 5 on the outer end face 11 of the mounting cover 1.

[0072] In this embodiment, the car logo component 2 and the light-emitting positioning element 5 are disposed on the outer end face 11 of the mounting cover 1, so that the airbag on the inner end face 12 of the mounting cover 1 does not directly contact the car logo component 2 and the light-emitting positioning element 5, and thus will not affect the detonation effect when the airbag is detonated.

[0073] This application provides a luminous car emblem, installed on a steering wheel, comprising: a mounting cover 1, an emblem assembly 2, a luminous positioning element 5, and a positioning connection structure 6; wherein, the mounting cover 1 is connected to the airbag of the steering wheel, and the outer end face 11 of the mounting cover 1 has a mounting position for accommodating the emblem assembly 2 and the luminous positioning element 5.

It is positioned opposite to the car logo assembly 2 through the positioning connection structure 6. The light-emitting positioning element 5 can emit light to the car logo assembly 2 to make the car logo 24 light up. After the car logo assembly 2 and the light-emitting positioning element 5 are respectively installed at the mounting position of the mounting cover 1, the outer end face 11 of the mounting cover 1 can present a flat structure.

[0074] This application places the car emblem component 2 and the luminous positioning element 5 on the outer end face 11 of the mounting cover 1, so that the airbag on the inner end face 12 of the mounting cover 1 does not directly contact the car emblem component 2 and the luminous positioning element, thus preventing any impact on the detonation effect when the airbag is deployed. Furthermore, corresponding injection molding structures are provided between the transparent layer 21, the IML film layer 22, and the connecting support layer 23, making the connection between these layers more stable and improving the stability of the luminous car emblem. In addition, the car emblem component 2 and the luminous positioning element 5 can be installed on the mounting cover 1 using only the positioning connection structure 6, and the outer end face 11 of the mounting cover 1 after installation has a flat structure, which not only simplifies the installation connection structure but also improves aesthetics.

[0075] Second Embodiment

[0076] This application provides a steering wheel airbag assembly, including an airbag and the aforementioned luminous vehicle emblem, wherein the airbag is housed within the mounting cover 1. The luminous vehicle emblem is described in the above embodiments and will not be repeated here.

[0077] Third Embodiment

[0078] This application embodiment also provides a molding process for an luminous car emblem, as shown in Figure 9. Figure 9 is a flowchart of a molding process for an luminous car emblem provided in this application embodiment. The molding process for the luminous car emblem includes the following steps:

[0079] Step S101: In the first injection molding die, an IML film layer with the car logo is formed by IML process.

[0080] Specifically, a base film suitable for IML (Integrated Molding Layer) processing is selected. The logo, bearing the vehicle emblem, is printed onto the base film using the IML process to form an initial IML film layer. Then, the initial IML film layer is placed in a first injection mold. Through the action of temperature and pressure, the initial IML film layer with the logo is shaped according to the required form. The shaped initial IML film layer is then cut to form an IML film layer with the vehicle emblem and a defined structure. The first injection mold is used to shape the initial IML film layer. In this embodiment, the IML process refers to printing ink onto the inner surface of a polymer film, hot-pressing the printed film into the 3D shape of the product, then cutting the outer shape and inner holes, placing it into the injection mold cavity, and injecting molding resin into the metal mold to bond with the film and solidify into the product. This molding method ensures the structure and performance of the plastic part while simultaneously providing the product surface with an aesthetically pleasing pattern and superior performance.

[0081] In step S102, a transparent material is used to process a transparent layer in the second injection molding die, 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 it, and the shaped structure of the transparent material is adapted to the structure of the IML film layer. The transparent material is acrylic or transparent PC (Polycarbonate). This transparent material gives the transparent layer a glass-like transparent texture. The second injection mold is used to injection mold the transparent material. After shaping the transparent material into a transparent layer in the second injection mold, the IML film layer is placed in the second injection mold, and positioned to match the transparent layer. The IML film layer and the transparent layer are then injection molded for the first time using the second injection mold to adhere the IML film layer to the transparent layer, forming a composite layer.

[0083] In step S103, a non-transparent material is used to process the composite layer and the connecting support layer in the third injection molding die to form a connecting support layer, and the composite layer and the connecting support layer are injection molded a second time to form a car logo component; the first end face of the connecting support layer may be injection molded with a partial positioning connection structure.

[0084] Specifically, a non-transparent material is placed in a third injection mold to shape it, and the shaped structure of the non-transparent material is adapted to the structure of the IML film layer and the transparent layer. The non-transparent material refers to PET (Polyethylene terephthalate). Specifically, when shaping the non-transparent material to form the connecting support layer, the shaped structure of the second end face of the connecting support layer is adapted to the structure of the IML film layer and the transparent layer. The first end face of the connecting support layer may be injection molded with a partial positioning connection structure, specifically an integrally molded positioning connection protrusion and a reverse limiting hook, or a welded pillar. Injecting a partial positioning connection structure into the first end face of the connecting support layer improves the stability of the connecting support layer connected to the mounting cover via the positioning connection structure. The third injection mold is used to injection mold the non-transparent material. After forming a connecting support layer from a non-transparent material in the third injection mold, a composite layer formed by injection molding the IML film layer and the transparent layer is placed in the third injection mold, and positioned to mate with the second end face of the connecting support layer. The composite layer and connecting support layer formed by injection molding the IML film layer and the transparent layer are then subjected to a second injection molding process using the third injection mold to form the vehicle logo component.

[0085] The luminous car logo molding process provided in this application uses different injection molding molds to form a transparent layer, an IML film layer, and a connecting support layer, making the injection molding between each layer precise and efficient. Furthermore, there are processing connections between each layer; that is, the second injection mold can perform the first injection molding of the IML film layer and the transparent layer, and the third injection mold can perform the second injection molding of the composite layer and the connecting support layer formed by the injection molding of the IML film layer and the transparent layer to form the car logo component. This improves both processing precision and processing efficiency.
