In the description of this application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0054] In the related art, the structure of the luminous car logo component on the steering wheel is relatively complex, and the luminous car logo component is heavy, which will affect the detonation effect when the airbag is detonated. In addition, the existing luminous car logo component needs to be used in conjunction with other hardening layers, and its performance is unstable.

[0057] Next, the luminous vehicle logo provided in the present 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 a part of the steering wheel, and the mounting cover 1 is connected to the airbag of the steering wheel, that is, the airbag is arranged on the inner end surface 12 side of the mounting cover 1. At an angle, the mounting cover 1 is approximately in a bow shape or a U shape. The outer end surface 11 of the mounting cover 1 has a mounting position for accommodating the vehicle logo assembly 2 and the luminous positioning element 5. The mounting position 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. Among them, the vehicle logo assembly 2 includes a transparent layer 21, an IML film layer 22, a connecting support layer 23 and a vehicle logo 24, and the transparent layer 21, the IML film 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 film layer 22, and the transparent layer 21 and the IML film layer 22 are connected by the first injection molding structure. Among them, in this embodiment, the first injection molding structure refers to the morphological structure required for the transparent layer 21 and the IML film layer 22 during injection molding. The first injection molding structure corresponding to each other is provided between the transparent layer 21 and the IML film layer 22, so that the transparent layer 21 and the IML film layer 22 can be quickly injected. Specifically, in one example, the first injection molding structure is arranged on the first end faces of the transparent layer 21 and the IML diaphragm layer 22 respectively, and the first injection molding structure includes a first accommodating cavity surface 31 and a first embedded surface structure 32, wherein the first accommodating cavity surface 31 refers to a structure having a cavity structure but only having an end face on one side. The first accommodating cavity surface 31 is arranged on the first end face of the transparent layer 21, and the first embedded surface structure 32 is arranged on the first end face of the IML diaphragm layer 22, and the first embedded surface structure 32 is attached to the first accommodating cavity surface 31 to realize the injection molding connection of the transparent layer 21 and the IML diaphragm layer 22. Among them, the transparent layer 21 has a glass transparent texture. The material of the transparent layer 21 is acrylic or transparent PC (Polycarbonate). The transparent material can make the transparent layer have a glass transparent texture.

[0062] The IML diaphragm layer 22 is located between the transparent layer 21 and the connecting support layer 23, and a second injection molding structure corresponding to each other is provided between the IML diaphragm layer 22 and the connecting support layer 23, and the IML diaphragm layer 22 and the connecting support layer 23 are connected by the second injection molding structure, wherein, 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 at the second end faces of the IML diaphragm layer 22 and the connecting support layer 23, respectively, and 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. The second accommodating cavity surface 41 is provided at the second end surface of the connecting support layer 23, the second embedded surface structure 42 is provided at the second end surface of the IML film layer 22, and the second embedded surface structure 42 is attached to the second accommodating cavity surface 41 to achieve the connection between the IML film 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 refers to PET (Polyethylene terephthalate) material.

[0063] Furthermore, in one example, the transparent layer 21, the IML film layer 22, and the connecting support layer 23 are rectangular, and the middle of the rectangle forms an inclined surface with respect 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 molding forms.

[0064] When the transparent layer 21, the IML film layer 22, and the connecting support layer 23 are rectangular, and the end faces on both sides of the middle of the rectangle form inclined surfaces, the first accommodating cavity surface 31 includes the first accommodating surface 311 and the first limiting connecting surface 312, and the second accommodating cavity surface 41 includes the second accommodating surface 411 and the second limiting connecting surface 412; wherein the first accommodating surface 311 and the second accommodating surface 411 are opposite to each other in the first direction, and the accommodating morphological structures of the first accommodating surface 311 and the second accommodating surface 411 are adapted, wherein the accommodating morphological structures of the first accommodating surface 311 and the second accommodating surface 411 are adapted to each other, which means that the morphological structures of the first accommodating surface 311 and the second accommodating surface 411 can be mutually attached or connected. 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 connected in sequence. The IML film layer 22 is arranged between the first accommodating surface 311 and the second accommodating surface 411. The first position-limiting connection surface 312 is relatively arranged on both sides of the first accommodating surface 311 in the second direction, and the first position-limiting connection surface 312 has a first position-limiting connection angle 313 relative to the first accommodating surface 311. Correspondingly, the second position-limiting connection surface 412 is relatively arranged on both sides of the second accommodating surface 411 in the second direction, and the second position-limiting connection surface 412 has a second position-limiting connection angle relative to the second accommodating surface 411. The first position-limiting connection surface 312 and the second position-limiting connection surface 412 are adapted and connected to realize the 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 are not only the injection molding shapes, but also have a certain limiting connection function, so that the transparent layer 21, the IML film layer 22 and the connection support layer 23 are 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, and this structural morphology can prevent the transparent layer 21, the IML film layer 22 and the connection support layer 23 from being observed as a layered structure, that is, although the transparent layer 21, the IML film layer 22 and the connection support layer 23 are multi-layer structures, after injection molding through this morphological structure, only the entire vehicle logo component 2 composed of the transparent layer 21, the IML film layer 22 and the connection support layer 23 can be seen in this direction.

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

[0067] In the present embodiment, the car logo 24 is presented on the transparent layer 21, and the transparent layer 21 has a glass transparent texture. Specifically, in one example, the car logo 24 is arranged 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 decoration hole 25, and the car logo decoration hole 25 is arranged on the connecting support layer 23, and the main body of the connecting support layer 23 is opaque. The car logo decoration 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 decoration hole 25 is adapted to the car logo 24, which means that the shape and size of the car logo decoration hole 25 are the same as the shape and size of the outer contour of the car logo 24, so that the car logo decoration 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 be 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, the positioning pins 66 are arranged in two, and are respectively located on the sides 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 be used as a 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 type of the first mounting groove 62 is set to a rectangle. The connecting card hole 63 is set corresponding to the welding column 61, and is set through the bottom of the groove of the first mounting groove 62. The connecting card hole 63 passes through the bottom of the groove 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 with the corresponding welding column 61. The positioning hole 67 is set corresponding to the positioning pin 66, and is set through the bottom of the groove of the first mounting groove 62, and the positioning hole 67 is connected with the positioning pin 66 for positioning. After the welding column 61 is inserted into the connection clamp 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 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, the second installation groove 64 is recessed at 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 away from the inner end surface 12 of the installation cover 1. The groove type 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 component 53 includes a power connector and a power transmission line, one end of the power transmission line is connected to the PCB board 52, and the other end of the power transmission line is connected to the power connector.

The forming process of the luminous vehicle logo comprises 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 that can be processed by the IML process is selected, and a logo with a car logo is printed on the base film through the IML process to form an initial IML film layer. Then, the initial IML film layer is placed in the first injection mold, and the initial IML film layer with the logo is shaped according to the required shape through the action of temperature and pressure, and the shaped initial IML film layer is cut to form an IML film layer with a car logo and a morphological structure. Among them, the first injection mold is used to shape the initial IML film layer. Among them, in this embodiment, the IML process refers to printing ink on the inner surface of the polymer film, hot pressing the printed film to form the 3D shape of the product, and then cutting the shape and inner hole, and then putting it into the injection mold cavity, injecting the molding resin into the metal mold, and bonding with the film to form a whole and solidify it into a product. A molding method that ensures the structure and performance of the plastic part while bringing beautiful patterns and superior performance to the product surface.

[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 subjected to a first injection molding 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. Wherein, the transparent material is acrylic or transparent PC (Polycarbonate). The transparent material can make the transparent layer have a glass transparent texture. The second injection mold is used to injection mold the transparent material. After the transparent material is shaped to form 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 by 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 connection support layer, and the composite layer and the connection support layer are injection molded for a second time to form a vehicle logo component; the first end surface of the connection 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 a partial positioning connection structure on the first end face of the connecting support layer 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 a connection support layer, the composite layer formed by injection molding of the IML membrane layer and the transparent layer is placed in the third injection mold, and the composite layer formed by injection molding of the IML membrane layer and the transparent layer is placed at a position that matches the second end face of the connection support layer. The composite layer formed by injection molding of the IML membrane layer and the transparent layer and the connection support layer are injection molded for a second time through the third injection mold to form a vehicle logo component.

[0085] The molding process of the luminous car logo provided in the embodiment of the present application forms a transparent layer, an IML film layer, and a connecting support layer through different injection molds, so that the injection molding between each layer is accurate and efficient. There is a processing connection 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 formed by the injection molding of the IML film layer and the transparent layer and the connecting support layer to form a car logo component, which improves the processing accuracy and the processing efficiency.
