[0050] Additionally, specific details are provided in the following description to facilitate a thorough understanding of the examples. However, those skilled in the art will understand that practice can be carried out without these specific details.

[0051] In existing technology, an airbag cover is typically placed over the airbag, and a tear line is provided on the airbag cover. When the airbag inflates and deploys, the airbag compresses the airbag cover, causing it to break off at the tear line. After the tear line is torn, part of the airbag cover, carrying the luminous emblem, flips along a certain rotation axis, allowing the airbag to extend and deploy.

[0052] In addition, decorative lines are added to the airbag cover to enhance its appearance. However, this design restricts the placement of the illuminated logo and the arrangement of wiring on the airbag cover.

[0053] Based on this, the embodiments of this specification propose a processing solution: such as Figure 2 As shown, this utility model provides a logo by extending the wire 40 along the flip axis 11. This prevents the wire 40 from being pulled off when the part along the airbag cover 10 is flipped along a certain flip axis 11, thus solving the problem that the wire 40 of the luminous logo is easily broken in the prior art.

[0054] The technical solutions provided by the various embodiments of this application are described below with reference to the accompanying drawings.

[0055] like Figures 1-6 As shown, this utility model discloses a logo applied to an airbag cover 10. At least a portion of the airbag cover 10 is capable of being flipped along a flipping axis 11. The logo includes a mounting component 20, a light-emitting component 30, a wire 40, and a marking component 50. The mounting component 20 is mounted on the airbag cover 10; the light-emitting component 30 is mounted on the mounting component 20; the wire 40 is connected to the light-emitting component 30 and extends outward from the mounting component 20, extending in the direction of the flipping axis 11; the marking component 50 covers the mounting component 20 and the light-emitting component 30.

[0056] The airbag cover 10 may have a tear line. When the airbag cover 10 is impacted by the airbag, the tear line breaks, causing part of the airbag cover 10 to flip along a certain flipping axis 11 that is approximately parallel to the tear line. At this time, the company emblem also flips along with the flipped part of the airbag cover 10.

[0057] In some embodiments, the airbag cover 10 may be provided with shaping lines to beautify the airbag cover 10. For example, two shaping lines may be arranged laterally on the outer surface of the airbag cover 10 and spaced apart, so that the logo is installed between the two shaping lines. In this case, the shaping lines restrict the installation position of the logo fixing wing.

[0058] The mounting member 20 is used to be fixedly mounted on the airbag cover plate 10 to provide a mounting base for the logo. The mounting member 20 can be clamped on the airbag cover plate 10 through a plurality of mounting members 20 such as slots, welding columns, etc.

[0059] The light emitting member 30 is used to emit light under the action of the lead wire 40, which can be a lamp bead or a lamp string.

[0060] The light emitting member 30 can be a printed circuit board (PCB board) with a lamp bead.

[0061] The lead wire 40 is used to connect the light emitting member 30 with an external power supply such as a BMS.

[0062] The logo member 50 is used to display the logo in cooperation with the light emitting member 30.

[0063] Specifically, when at least part of the airbag cover plate 10 is impacted and flipped along a certain flip axis 11, the logo is flipped with the flipped part of the airbag cover plate 10. At this time, the lead wire 40 is extended towards the flip axis 11, so that the lead wire 40 will not be excessively pulled and thus is prevented from being pulled off.

[0064] Preferably, the extension direction of the lead wire 40 is substantially perpendicular to the flip axis 11.

[0065] In some embodiments, as shown in Figure 3 , part of the airbag cover plate 10 is flipped towards the six o'clock direction or the twelve o'clock direction of the steering wheel, and the lead wire 40 is extended towards the six o'clock direction or the twelve o'clock direction of the steering wheel to cope with the airbag cover plate 10 being provided with a transverse modeling line or a transverse tear line.

[0066] Herein, the transverse direction is the three o'clock to nine o'clock direction of the steering wheel when the airbag cover plate 10 is mounted on the steering wheel.

[0067] For example, when two modeling lines are arranged at intervals on the airbag cover plate 10, the tear line is arranged in correspondence with one of the modeling lines, and at this time, the logo is arranged between the two modeling lines, and part of the airbag cover plate 10 is flipped towards the six o'clock direction or the twelve o'clock direction of the steering wheel, and the lead wire 40 is extended towards the six o'clock direction or the twelve o'clock direction of the steering wheel to avoid being pulled off.

[0068] Further, as shown in Figure 2 , 4 , the mounting member 20 is provided with a lead wire groove 21, and the lead wire 40 extends from the lead wire groove 21 to the outside of the mounting member 20 to protect the lead wire 40, so as to avoid the lead wire 40 being crushed by the mounting member 20 and the airbag cover plate 10 and thus being broken or disconnected when part of the airbag cover plate 10 is flipped.

[0069] The wire slot 21 extends from the inner side of the mounting piece 20 to the outer side of the mounting piece 20 and has a certain depth to completely accommodate the wire 40.

[0071] The wire track 22 is provided with a wire slot for accommodating the wire 40.

[0072] The longitudinal section of the wire track 22 can be in an inverted Ω structure.

[0073] Preferably, the wire track 22 cooperates with the inner wall of the airbag cover plate 10 to form an accommodation space 23 for accommodating the wire 40 to avoid the wire being pressed to break or disconnect.

[0074] In the present application, the bending direction of the wire track 22 is the same as the bending direction of the airbag cover plate 10, so that after the mounting piece 20 is mounted on the airbag cover plate 10, the wire track 22 and the inner wall of the airbag cover plate 10 fit to form a closed accommodation space 23.

[0075] Further, the mounting piece 20 further comprises a mounting slot 24 for accommodating the light-emitting piece 30, and the mounting slot 24 is formed with a support portion 25 for supporting the light-emitting piece 30; the side wall of the mounting slot 24 is provided with a plurality of limiting columns 26 for limiting the light-emitting piece 30 in cooperation with the limiting grooves on the light-emitting piece 30.

[0080] The light guide plate 60 is used to uniformly distribute the light of the light-emitting piece 30, so that the light is more uniformly transmitted to the lens 51.

[0081] The light guide plate 60 is made of a light-transmitting material.

[0082] Further, as shown in Figure 6 the mounting groove 24 is provided with a positioning groove 27 matched with the positioning wing 61, and the positioning groove 27 is used to position the light guide plate 60 in the mounting groove 24 to avoid rotation of the light guide plate 60 during use.

[0083] Further, as shown in Figure 4 , 7 the sign member 50 includes a lens 51 and a sign part 52. The lens 51 covers the light emitting member 30 and is connected to the mounting member 20 perpendicularly to the turning direction of the airbag cover plate 10; and the sign part 52 is arranged on the side of the lens 51 away from the light emitting member 30.

[0084] The two sides of the lens 51 are provided with mounting wings, and the lens 51 is connected to the mounting member 20 through the mounting wings, for example, clamping.
