[0030] The core of the present utility model lies in disclosing a vehicle lamp lighting device to reduce the occupied space of the vehicle lamp.

[0031] Another core of the present utility model lies in disclosing a vehicle including the above-mentioned vehicle lamp lighting device.

[0032] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0033] As Figure 1 shown, the embodiments of the present utility model disclose a vehicle lamp lighting device, including a bracket 4, a circuit board 5, and an optical fiber 1.

[0034] Among them, the circuit board 5 is connected to the bracket 4, preferably in a detachable connection manner. A light-emitting element 51 is provided on the circuit board 5, and the light-emitting element 51 is preferably an LED. An optical fiber crystal head 2 is provided on the optical fiber 1, and the optical fiber crystal head 2 is connected to the bracket 4, and the optical fiber crystal head 2 is located in the light-emitting direction of the light-emitting element 51.

[0035] The light emitted by the light-emitting element 51 irradiates onto the optical fiber crystal head 2 and is transmitted through the optical fiber 1. The shape of the optical fiber 1 shown in the figure is only an example. In actual applications, the optical fiber 1 can be bent in various ways according to the shape of the vehicle lamp.

[0036] The vehicle lamp lighting device disclosed in the embodiments of the present utility model only includes a bracket 4, a circuit board 5, and an optical fiber 1. Compared with the prior art, which includes multiple components such as a circuit board 5, a light guide bar, a thick wall, and a reflector lamp, it can reduce the number of parts, thereby reducing the occupied space of the vehicle lamp and can flexibly adapt to the modules with various signal lamp functions. At the same time, the use of the optical fiber 1 can improve the uniformity of light emission and can meet the diversification of the vehicle lamp shape.

[0037] In some specific embodiments, for the convenience of disassembly and assembly, the optical fiber crystal head 2 is detachably connected to the bracket 4, and specifically, it can adopt a snap connection method or a connection method using a connecting piece.

[0038] As Figure 1 shown, in some specific embodiments, the bracket 4 includes an installation cavity 41 capable of installing the circuit board 5 and an installation groove 42 capable of accommodating the fiber optic crystal head 2, and the installation cavity 41 communicates with the installation groove 42.

[0039] As Figures 1-4 shown, in some specific embodiments, the installation groove 42 is a C-shaped groove, a clamping post is provided on the fiber optic crystal head 2, and a clamping portion cooperating with the clamping post is provided in the installation groove 42. Figure 4 The clamping portion described above is a protrusion, and there are two clamping posts. When the fiber optic crystal head 2 is installed in place with the bracket 4, the clamping posts abut against the clamping portion to limit the fiber optic crystal head 2 and prevent the fiber optic crystal head 2 from detaching from the opening of the C-shaped groove. At the same time, a fiber optic accommodating groove is provided on the installation groove 42 to clamp and fix the fiber optic 1. As Figure 6 shown, in order to limit the fiber optic crystal head 2 in the axial direction of the bracket 4, the height of the portion of the fiber optic crystal head 2 where the clamping post is provided is greater than the height of the fiber optic accommodating groove, and the C-shaped groove is convenient for installing the fiber optic crystal head 2.

[0040] As Figure 1 shown, in order to seal the circuit board 5, the vehicle headlamp lighting device further includes a sealing ring 3. The sealing ring 3 is provided on the fiber optic crystal head 2 and is located at one end close to the circuit board 5. When the fiber optic crystal head 2 is installed on the bracket 4, the sealing ring 3 abuts against the bracket 4 to seal the circuit board 5, specifically as Figures 5-6 shown.

[0041] During installation, first install the sealing ring 3 on the fiber optic crystal head 2, then insert the fiber optic crystal head 2 into the C-shaped groove from the opening, and then move the fiber optic crystal head 2 along the axial direction of the bracket 4 towards the circuit board 5 so that the sealing ring 3 abuts against the bracket 4 and at the same time the clamping posts abut against the clamping portion. In some other specific embodiments, a sealing ring accommodating groove is further provided on the bracket 4 to facilitate positioning of the sealing ring 3.

[0042] On the basis of the above embodiments, in order to further seal the circuit board 5, a sealant 6 is provided between the back surface of the circuit board 5 (here refers to the surface opposite to the surface where the light-emitting element 51 is provided) and the bracket 4. Specifically, during installation, after the circuit board 5 and the bracket 4 are installed, the back surface of the circuit board 5 is subjected to potting treatment. Of course, a sealing ring 3 can also be provided on the back surface of the circuit board 5. The settings of the sealing ring 3 and the sealant 6 can improve the reliability and service life of the circuit board 5 and protect the stability and safety of the circuit board 5. The vehicle headlamp lighting device disclosed by the present utility model has self-sealing performance, can be independently installed at the vehicle body position, or can be put into the combined headlamp as a part of the signal lamp shape, and is flexible to use.

[0043] In some other specific embodiments, the fiber optic connector 2 is snap-connected to the bracket 4. A snap block is provided on one of the fiber optic connector 2 and the bracket 4, and a card slot cooperating with the snap block is provided on the other. This method can position the fiber optic connector 2 and prevent the fiber optic connector 2 from rotating at the same time.

[0044] In some specific embodiments, the circuit board 5 is snap-connected to the bracket 4 or connected through a connecting member, and can be connected by means of bolt connection.

[0045] The headlight lighting device disclosed in the embodiment of the present utility model further includes a radiator for dissipating heat from the circuit board 5. The radiator is connected to the circuit board 5. Specifically, the radiator includes heat dissipation fins.

[0046] In addition, the embodiment of the present utility model also discloses a vehicle including the above-mentioned headlight lighting device, and thus has all the technical effects of the above-mentioned headlight lighting device, which will not be elaborated here.
