[0040] 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 fall within the protection scope of the present utility model.
[0041] As Figure 3 shown, the embodiment of the present utility model discloses a light guide fixing structure, including a light guide bracket 20 and a light guide clip 30.
[0042] As Figure 6 shown, a light guide receiving groove 21 capable of receiving the light guide 10 is provided on the light guide bracket 20. As Figures 8 - 10 shown, the light guide clip 30 includes a first light guide clip 32 and a second light guide clip 33. The first light guide clip 32 and the second light guide clip 33 are detachably connected. When the two are in a connected state, a space capable of receiving the light guide 10 is formed to fix the light guide 10.
[0043] Specifically, both the first light guide clip 32 and the second light guide clip 33 are semi-circular structures. When the two are connected, a circular ring structure is formed. The light guide clip 30 and the light guide bracket 20 are detachably connected to fix the light guide 10.
[0044] It should be noted that the light guide clip 30 includes at least two, preferably disposed at the end of the light guide 10. The connection manner between the first light guide clip 32 and the second light guide clip 33 can adopt a bolt connection manner or a snap connection manner. The specific connection manner is not limited. The extension direction of the light guide bracket 20 can be specifically determined according to the extension direction of the light guide 10 to adapt to light guides 10 with different trajectories.
[0045] During actual use, as Figure 11As shown, first, each light guide clip 30 is fixed to both ends of the light guide 10 respectively. Subsequently, the light guide clip 30 is connected to the light guide bracket 20, and the fixation of the light guide 10 can be completed.
[0046] The light guide fixing structure disclosed in the embodiment of the present utility model uses the cooperation of the light guide clip 30 and the light guide bracket 20 to fix the light guide 10, with simple assembly and convenient installation. Compared with the prior art method of integrating the installation structure on the light guide 10, it can improve the phenomenon of forming bright spots or dark spots visually when the light guide 10 is lit, improve the uniformity of the light emission of the light guide 10, ensure a good light emission effect, and at the same time reduce the light energy loss of the light guide 10 and improve the energy utilization rate.
[0047] In some specific embodiments, such as Figure 10 As shown, the light guide clip 30 includes a plurality of elastic members 31 arranged circumferentially. The plurality of elastic members 31 form a structure similar to a "petal structure" to form a clamping structure capable of clamping the light guide 10, so as to clamp the light guide 10 and reduce the risk of the light guide 10 falling off. Specifically, as Figure 8 and Figure 9 As shown, some of the plurality of elastic members 31 are arranged on the first light guide clip 32, and the other part of the elastic members 31 are arranged on the second light guide clip 33. The arrangement of the plurality of elastic members 31 can adapt to light guides 10 with different diameters. Of course, light guide clips 30 with different specifications can also be made to adapt to light guides 10 with different specifications.
[0048] Specifically, each elastic member 31 extends radially along the light guide clip 30. When the light guide clip 30 is installed on the light guide 10, each elastic member 31 abuts against the light guide 10. As Figure 5 As shown, the figure shows that the elastic member 31 includes eight arranged circumferentially at intervals along the light guide clip 30, and the eight elastic members 31 are all bent in the same direction. In the figure, each shown elastic member 31 is bent clockwise to form a clamping structure capable of clamping the light guide 10. It should be noted that the specific number and bending direction of the elastic member 31 are specifically set according to actual needs. This is only an example here and cannot be used as a limitation. In order to increase the contact area with the light guide 10, each elastic member 31 is preferably in a sheet structure.
[0049] Such as Figures 8 - 9 As shown, in some specific embodiments, the first end of the first light guide clip 32 and the first end of the second light guide clip 33 are hingedly connected, and the second end of the first light guide clip 32 and the second end of the second light guide clip 33 are snap-connected. As Figure 9As shown, during actual use, the second ends of the first optical waveguide clip 32 and the second optical waveguide clip 33 are separated. The second optical waveguide clip 33 is disposed at the end of the optical waveguide 10, and then the second end of the first optical waveguide clip 32 is buckled towards the second end of the second optical waveguide clip 33 so that the first optical waveguide clip 32 and the second optical waveguide clip 33 are snap-connected. Figure 10 The figure shows a schematic structural view of the snap connection in place. The first optical waveguide clip 32 and the second optical waveguide clip 33 are buckled to fix the optical waveguide 10.
[0050] Specifically, a snap projection can be provided on one of the first optical waveguide clip 32 and the second optical waveguide clip 33, and a snap groove cooperating with the snap projection can be provided on the other; or a snap connection can be used, where a locking hook is provided on one of the first optical waveguide clip 32 and the second optical waveguide clip 33, and a hanging member cooperating with the locking hook is provided on the other; or other snap connection methods can be used.
[0051] In some other specific embodiments, the second end of the first optical waveguide clip 32 and the second end of the second optical waveguide clip 33 can also be connected by a connecting member, such as by a bolt.
[0052] As Figure 4 shown, in some specific embodiments, a first hook 321 is provided on the first optical waveguide clip 32, and a second hook 331 is provided on the second optical waveguide clip 33. The bending directions of the first hook 321 and the second hook 331 are opposite. In the figure, the bending direction of the first hook 321 is upward, and the bending direction of the second hook 331 is downward. When the first optical waveguide clip 32 and the second optical waveguide clip 33 are buckled, the first hook 321 and the second hook 331 are buckled together. This setting method is convenient for installation. In some other specific embodiments, a bayonet cooperating with the first hook 321 can be provided on the second optical waveguide clip 33.
[0053] As Figure 6 shown, in some specific embodiments, the optical waveguide bracket 20 includes an optical waveguide receiving groove 21 and an optical waveguide clip mounting portion 22. The optical waveguide clip mounting portion 22 is connected to the optical waveguide receiving groove 21 through a connecting portion. To adapt to the trajectory of the optical waveguide 10, the connecting portion is inclined and inclined in the direction from the optical waveguide receiving groove 21 to the optical waveguide clip mounting portion 22. The optical waveguide clip 30 is connected to the optical waveguide clip mounting portion 22.
[0054] Specifically, the optical waveguide clip 30 is snap-connected to the optical waveguide clip mounting portion 22. A snap 34 is provided on one of the optical waveguide clip 30 and the optical waveguide clip mounting portion 22, and a card slot 23 cooperating with the snap 34 is provided on the other.
[0055] As Figure 12 and Figure 13As shown, in some specific embodiments, the buckle 34 is provided on the light guide clip 30, and the card slot 23 is provided on the light guide clip mounting portion 22. To ensure the firm connection between the light guide clip 30 and the light guide bracket 20, two buckles 34 are provided and are respectively located on both sides of the light guide 10, and the card slots 23 correspond to the buckles 34 one by one. To further improve the firm connection between the light guide clip 30 and the light guide bracket 20, the setting directions of the engaging portions of the two buckles 34 are different, and the setting directions of the notches of the corresponding two card slots 23 are different. The notch of one of the card slots 23 faces the end of the light guide 10, and the notch of the other card slot 23 faces the center of the light guide 10.
[0056] In some specific embodiments, such as Figure 12 As shown, a groove 221 is provided on the light guide clip mounting portion 22. When the light guide clip 30 is connected to the light guide bracket 20, the light guide clip 30 is mounted in the groove 221.
