[0029] The core of this application is to provide a mounting structure for a lamp housing to improve the utilization rate of the lamp housing.

[0030] Another core of the present application is to provide a lamp housing having the above-mentioned mounting structure for the lamp housing.

[0031] Another core of the present application is to provide a vehicle lamp having the above-mentioned lamp housing.

[0032] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0033] The spring nut inserts a spring sheet between the nut and the screw so that when the screw is tightened, the spring sheet will deform and cling to the part to be fixed, thereby generating additional friction and locking force to achieve a tightening effect.

[0034] In the related field, U-shaped spring nuts are usually used to connect and fix the lamp housing and the sheet metal structure. However, since the U-shaped spring nut structure is U-shaped, the U-shaped spring nut limits the thickness and structural form of the lamp housing, reduces the strength of the lamp housing, and the U-shaped spring nut occupies a large space, reducing the utilization rate of the lamp housing.

[0035] For this reason, Figure 1As shown, the embodiment of the present application discloses a mounting structure for a lamp housing, comprising a spring nut 100 and a lamp housing mounting portion 300. By using a single-layer spring 101 to be inserted into a slot 3011 formed at the bend 301 of the lamp housing mounting portion 300, the space occupied by the spring nut 100 can be reduced, material costs can be reduced, and the utilization rate of the lamp housing can be improved. At the same time, the thickness of the lamp housing can be increased to ensure the strength of the lamp housing.

[0036] The following will be combined Figures 1 to 3 The mounting structure for the lamp housing disclosed in the embodiment of the present application is specifically explained and illustrated.

[0037] Among them, such as Figure 1 and Figure 2 As shown, the spring nut 100 includes a spring piece 101 and a boss 102 arranged on the spring piece 101, and a first mounting hole 1021 is opened at the center position of the boss 102, and an internal thread portion is provided on the inner wall of the first mounting hole 1021 so that the first mounting hole 1021 can be threadedly matched with the fastener 200. At the same time, the lamp housing mounting portion 300 is provided with a bent portion 301 and a second mounting hole 302 adapted to the first mounting hole 1021. The second mounting hole 302 can be a light hole, and a slot 3011 is formed at the position of the bent portion 301. When the spring piece 101 is inserted into the slot 3011, the first mounting hole 1021 and the second mounting hole 302 are aligned. At this time, the lamp housing and the structure to be connected can be fixed from one side of the structure to be connected by the fastener 200. Therefore, by using a single layer of spring piece 101 to be inserted into the slot 3011 formed at the position of the bent portion 301 of the lamp housing mounting portion 300, the space occupied by the reed nut 100 is saved, material costs are reduced, and the utilization rate of the lamp housing is improved. At the same time, the space saved by the reed nut 100 can be used to increase the thickness of the lamp housing to ensure the strength of the lamp housing. It should be noted that the lamp housing mounting portion 300 is located on the lamp housing and can be integrally injection molded with the lamp housing. The structure to be connected may be a sheet metal structure or other accessories connected to the lamp housing.

[0038] In order to improve the fastening force of the reed nut 100, in some embodiments, as Figure 3 As shown, a limiting protrusion 1011 is provided on the spring nut 101, so that when the fastener 200 is tightened, the limiting protrusion 1011 abuts against the bent portion 301 of the lamp housing mounting portion 300, thereby improving the fastening force of the spring nut 100. At the same time, the protruding direction of the limiting protrusion 1011 is consistent with the bending direction of the bent portion 301. When the fastener 200 is tightened, the limiting protrusion 1011 on the spring nut 100 is forced upward to abut against the bent portion 301 of the lamp housing mounting portion 300, without exerting pressure on the main structure of the lamp housing below the lamp housing mounting portion 300, thereby effectively reducing the risk of lamp housing deformation.

[0039] In some embodiments, as Figures 1 to 3 As shown, the protruding direction of the limiting protrusion 1011 is consistent with the direction of the boss 102. In addition, two bending portions 301 can be used, and an avoidance space 3012 is formed between the two bending portions 301 to avoid the boss 102, so as to prevent the boss 102 on the spring nut 100 from interfering with the lamp housing mounting portion 300. At the same time, the limiting protrusion 1011 can include at least two, and the two limiting protrusions 1011 can be symmetrically arranged along the boss 102, so that the two limiting protrusions 1011 respectively abut against the two bending portions 301. Of course, the limiting protrusions 1011 can also be three, four, five or more, and each limiting protrusion 1011 is located on both sides of the boss 102 to abut against the two bending portions 301.

[0040] In order to prevent the reed nut 100 from being misconnected, in some embodiments, as Figures 1 to 3 As shown, a limiting portion 1012 is provided on the spring piece 101. For ease of understanding, the two opposite ends of the spring piece 101 are defined as a first end and a second end, respectively. The first end of the spring piece 101 can be inserted into the slot 3011, and the limiting portion 1012 is provided on the second end of the spring piece 101, so that the limiting portion 1012 cooperates with the bent portion 301 to position the installation direction of the spring nut 100, thereby preventing the spring nut 100 from being misconnected, resulting in the fastener 200 being unable to threadably engage with the first mounting hole 1021 of the boss 102. Specifically, the second end of the spring piece 101 can be bent at a preset angle toward the bent portion 301 to form the limiting portion 1012, so that the installation direction of the spring nut 100 can be determined by determining the direction of the limiting portion 1012 and the bent portion 301. It should be noted that the preset angle can be 90°, 120°, 135°, etc., as long as the preset angle is between 0° and 180°, and this document does not limit it here.

[0041] An embodiment of the present application also discloses a lamp housing, comprising a shell and a sheet metal part, wherein the shell and the sheet metal part are connected via a mounting structure, and the mounting structure is the mounting structure for the lamp housing disclosed in the above embodiment, and therefore has all the technical effects of the above mounting structure, which will not be repeated herein.

[0042] The embodiment of the present application further discloses a vehicle lamp, comprising a lamp housing as disclosed in the above embodiment. Therefore, the lamp housing has all the technical effects of the above lamp housings, which will not be described in detail herein.

[0043] The terms "first," "second," and so on in the specification, claims, and drawings of this application are used to distinguish between different items, not to describe a specific order. Furthermore, the terms "including," "having," and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or elements is not limited to the listed steps or elements and may include steps or elements that are not listed.

Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application.
