[0001] The present application relates to the field of vehicles, and in particular to a decorative structure, a lamp and a vehicle. Background Art

[0002] At present, in order to meet the overall vehicle styling, more and more decorative parts have appeared. Many decorative parts are connected to the light distribution mirror of the lamp. Due to the special structure of the decorative parts themselves and the limitation of the shape of the light distribution mirror, the installation stability of the decorative parts is not high after being connected to the light distribution mirror and they are easy to fall off the light distribution mirror. Summary of the Invention

[0003] The purpose of the embodiments of the present application is to provide a decorative structure, a lamp and a vehicle to solve the technical problem of low installation stability of decorative parts in the prior art.

[0004] To achieve the above objectives, the technical solution adopted in this application is: on the one hand, a decorative structure is provided, comprising:

[0005] A bracket, used for detachable connection with the target light distribution lens;

[0006] The decorative piece is clamped on the bracket and forms a preset decorative shape on a side away from the bracket.

[0007] The decorative element comprises a decorative portion for forming the decorative shape and a clamping portion for connecting with the decorative portion;

[0008] The buckle is detachably connected to the clamping portion and the bracket respectively.

[0009] Compared to the prior art, the decorative structure of the present application has the following beneficial effects: the decorative part is connected to the target lens via a bracket. Since the bracket can be flexibly configured to adapt to the shape of the decorative part and the lens, when the decorative part is indirectly connected to the lens via the bracket, the bracket can provide a better connection stability between the decorative part and the lens. By independently processing the decorative portion and the clamping portion, not only can the processing difficulty of the decorative part be reduced and the decorative part meet higher appearance requirements, but the decorative part can also be more stably clamped to the bracket via the clamping portion, thereby improving its own installation stability. By providing a clip that can be clamped to the clamping portion and the bracket respectively, not only can the processing difficulty of the decorative part be further reduced, but the clamping portion can also be more stably clamped to the bracket, effectively improving the installation stability of the decorative part.

[0010] On the other hand, the present application also provides a lamp having the decorative structure as described above, and also includes a light distribution mirror, the light-emitting surface of which is recessed toward the inside of the lamp to form a receiving groove, and the bracket and the decorative component are located inside the receiving groove.

[0011] Compared with the prior art, the beneficial effect of the lamp in the present application is that: by forming a receiving groove on the light-emitting surface of the photometric mirror, the present application not only prevents the decorative part from protruding from the photometric mirror, but also utilizes the receiving groove to form a protective effect on the bracket and decorative part inside the receiving groove, which is conducive to further improving the installation stability of the decorative part.

[0012] Optionally, the light distribution lens has a plurality of connecting posts protruding from the bottom of the receiving groove along the depth of the receiving groove. The connecting posts and the bracket form corresponding screw holes along the extension direction of the connecting posts and are connected to each other via a connecting member axially inserted into the screw holes. In this solution, the connecting posts protruding from the bottom of the receiving groove can form longer screw holes for connecting to the bracket by utilizing the space in the depth direction of the receiving groove, which further improves the installation stability of the bracket, and thus further improves the installation stability of the decorative component.

[0013] Optionally, a main positioning post is provided on the lens, adjacent to and connected to the connecting post. The main positioning post is slidably connected to the bracket and can provide a sliding guide for the bracket during the threaded connection between the bracket and the connecting post. In this solution, the main positioning post's sliding connection with the bracket not only enables the bracket to be installed into the receiving slot more efficiently, but also forms a support and limit position for the bracket after it is installed and secured, thereby further improving the installation stability of the bracket, and thus further improving the installation stability of the decorative component.

[0014] Optionally, the lens is provided with an auxiliary positioning post spaced apart from the main positioning post. The auxiliary positioning post is slidably connected to the bracket and can provide a sliding guide for the bracket during the threaded connection between the bracket and the connecting post. In this solution, the provision of an auxiliary positioning post that cooperates with the main positioning post not only improves the efficiency and stability of the bracket installation process, but also cooperates with the main positioning post to form at least two spaced-apart abutment locations between the lens and the bracket, further improving the installation stability of the bracket, and thus further improving the installation stability of the decorative component.

[0015] Optionally, the bottom of the receiving groove is provided with a plurality of auxiliary positioning surfaces, which mate with the surface shape of the bracket and can provide sliding guidance for the bracket during installation and removal from the receiving groove. In this solution, the auxiliary positioning surfaces provided at the bottom of the receiving groove not only enable the bracket to be installed into the receiving groove more efficiently, but also cooperate with the main positioning column and the auxiliary positioning column to limit the bracket, thereby preventing the bracket from shaking in the receiving groove, which helps to further improve the installation stability of the bracket, and thus further improve the installation stability of the decorative component.

[0016] Optionally, the auxiliary positioning surfaces are provided with at least two adjacent groove walls extending in different directions from the receiving groove; the auxiliary positioning surfaces extend in the same direction as the adjacent groove walls. In this embodiment, the at least two auxiliary positioning surfaces can be arranged around the bracket, thereby better limiting the bracket from rocking in the receiving groove, further improving the bracket's installation stability, and thus further improving the installation stability of the decorative component.

[0017] On the other hand, the present application also provides a vehicle having any of the above-mentioned lamps. Compared with the prior art, since the vehicle provided in the present application includes any of the above-mentioned lamps, it also has at least the beneficial effects of the above-mentioned lamps, which will not be repeated here.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0031] Please also refer to Figure 1 、 Figure 2 and Figure 3 A decorative structure provided in an embodiment of the present application will now be described. The decorative structure includes a bracket 101 and a decorative member 102. The bracket 101 is configured to be detachably connected to the target lens 200, while the decorative member 102 is snap-fitted to the bracket 101 and forms a predetermined decorative shape on a side facing away from the bracket 101.

[0032] According to the structure of the bracket 101 and decorative member 102 provided in this embodiment, the function of the bracket 101 is to connect the decorative member 102 and the target lens 200. Because the bracket 101 can be flexibly configured to adapt to the shapes of the decorative member 102 and the lens 200, it can effectively solve the problem of poor connection stability between the decorative member 102 and the lens 200 caused by the unique shapes of the decorative member 102 and the lens 200 in the prior art. When the decorative member 102 is indirectly connected to the lens 200 via the bracket 101, the bracket 101 can achieve better connection stability between the decorative member 102 and the lens 200, thereby achieving better installation stability for the decorative member 102 in this application, far superior to the prior art.

[0033] It will be understood that the methods for detachably connecting the bracket 101 to the lens 200 in this embodiment include, but are not limited to, commonly used methods in the art, such as snap connections, rivet connections, or threaded connections formed by screws 203 or bolts. The snap connections between the decorative member 102 and the bracket 101 can employ commonly used methods in the art, such as damping connections, interference fit connections, and snap connections formed by the cooperation of a block and a slot. Other snap connections in the art that allow for detachable connection of the bracket 101 to the lens 200, as well as other snap connections that allow for snapping of the decorative member 102 to the bracket 101, can be considered common variations of the aforementioned connection methods in this embodiment and will not be further described here.

[0034] In another embodiment of this application, please refer to Figure 1 、 Figure 2 and Figure 3 The decorative element 102 has a decorative portion 121 for forming a decorative shape and a clamping portion 122 for connecting with the decorative portion 121 . The decorative element 102 is clamped with the bracket 101 via the clamping portion 122 .

[0035] According to the above structure provided in this embodiment, since the decorative part 102 has independently processed decorative parts 121 and clamping parts 122, this can not only reduce the processing difficulty of the decorative part 102 and enable the decorative part 102 to meet higher appearance requirements, but also enable the decorative part 102 to be more stably clamped to the bracket 101 through the clamping part 122 and improve its own installation stability.

[0036] It is understood that, in order to meet higher aesthetic requirements for the decorative member 102, the decorative portion 121 and the clip portion 122 in this embodiment can also be configured to be detachably connected. For example, in this embodiment, the decorative portion 121 and the clip portion 122 can be configured to be bonded to each other. By configuring the decorative member 102 to be formed by bonding the clip portion 122 and the decorative portion 121 together, not only can the decorative portion 121 be more easily processed to meet higher aesthetic requirements, but the clip portion 122 can also be more easily processed, thereby enabling the clip portion 122 to be more stably attached to the bracket 101, further improving the installation stability of the decorative member 102.

[0037] In addition, the clipping portion 122, which can be separated from the decorative portion 121 and independently processed, can be clipped to the bracket 101 in a more flexible manner, which helps significantly reduce the overall structural dimensions of the decorative member 102 and enables the decorative member 102 provided in this embodiment to meet higher appearance requirements. For example, the clipping portion 122, which can be independently processed in this embodiment, can be configured as a flat card structure and clipped to a slot structure provided on the bracket 101, thereby achieving the above-mentioned technical effect of reducing the overall structural dimensions of the decorative member 102. Of course, other structures in the art that can reduce the dimensions of the clipping structure between the decorative member 102 and the bracket 101 can also be considered common variations of the structure described above in this embodiment and will not be described in detail here.

[0038] In another embodiment of this application, please refer to Figure 1 、 Figure 2 and Figure 3 The decorative structure further includes a buckle 103, which is detachably connected to the clamping portion 122 and the bracket 101 respectively.

[0039] According to the above structure provided in this embodiment, the buckle 103 that can be respectively engaged with the engaging portion 122 and the bracket 101 can not only further reduce the processing difficulty of the decorative part 102, but also enable the engaging portion 122 to be more stably engaged with the bracket 101, and effectively improve the installation stability of the decorative part 102.

[0040] It is understood that in this embodiment, the buckle 103 can be configured as a commonly used snap-fit ​​structure in the art, and by snapping it into the slot on the bracket 101 or the snap-fit ​​portion 122, the decorative member 102 and the bracket 101 can be quickly snapped together. Of course, in this embodiment, the buckle 103 can also be provided with a snap-fit ​​slot corresponding to the bracket 101 and the snap-fit ​​portion 122, which can also achieve a quick snap-fit ​​connection between the decorative member 102 and the bracket 101. In other embodiments of the present application, the buckle 103 can also be configured to be integrally formed with the bracket 101 or the snap-fit ​​portion 122, respectively, to achieve a similar snap-fit ​​effect as in this embodiment, which will not be repeated here.

[0041] Please also refer to Figure 2 、 Figure 3 and Figure 4 A lamp provided in an embodiment of the present application will now be described.

The main positioning column 204 is slidably connected to the bracket 101 and can provide a sliding guide for the bracket 101 during the threaded connection process between the bracket 101 and the connecting column 202.

[0048] According to the above structure provided in this embodiment, the main positioning column 204 can not only enable the bracket 101 to be installed in the accommodating groove 201 more efficiently through the sliding connection with the bracket 101, but also form a support limit for the bracket 101 after the bracket 101 is installed and fixed, which is beneficial to further improve the installation stability of the bracket 101, thereby further improving the installation stability of the decorative part 102.

[0049] It can be understood that the cross-sectional shape of the main positioning column 204 in this embodiment is not limited, and can be set to a circular, rectangular or polygonal structure commonly used in the art. In addition, the main positioning column 204 can also be provided with a positioning structure such as a slide groove, a slide rail, etc. for corresponding to the bracket 101 and enabling the bracket 101 to slide relative to the positioning column. This embodiment is a preferred embodiment, and the main positioning column 204 is set as a step with a circular cross-section as an example for explanation. In the lamp provided in this embodiment, the main positioning column 204 can use its inclined annular side wall as the positioning structure of the bracket 101 and form abutment against the bracket 101 after the bracket 101 and the connecting column 202 are installed in place, which can provide better installation stability for the bracket 101.

[0050] In another embodiment of this application, please refer to Figure 2 、 Figure 3 and Figure 4 The light distribution mirror 200 is provided with an auxiliary positioning column 205 spaced apart from the main positioning column 204. The auxiliary positioning column 205 is slidably connected to the bracket 101 and can provide a sliding guide for the bracket 101 during the threaded connection process between the bracket 101 and the connecting column 202.

[0051] According to the above structure provided in this embodiment, by providing an auxiliary positioning column 205 that cooperates with the main positioning column 204, not only can the efficiency and stability of the bracket 101 during installation be improved, but the auxiliary positioning column 205 can also cooperate with the main positioning column 204 to form at least two abutment positions spaced apart between the lens 200 and the bracket 101, which is beneficial to further improve the installation stability of the bracket 101, thereby further improving the installation stability of the decorative part 102.

[0052] It can be understood that the cross-sectional shape of the auxiliary positioning column 205 in this embodiment is not limited, and can be set to a circular, rectangular or polygonal structure commonly used in the art. In addition, the auxiliary positioning column 205 can also be provided with a positioning structure such as a slide groove, a slide rail, etc. for corresponding to the bracket 101 and enabling the bracket 101 to slide relative to the auxiliary positioning column 205.
