[0002] Bicycles are a very popular means of transportation at present. With the advocacy of green travel and the need for fitness and exercise, more and more cycling enthusiasts are joining in.

[0003] As people's living standards improve, the requirements for bicycles are getting higher and higher. For safety reasons, headlights are installed.

[0004] Since bicycles are exposed to the outside for a long time, they are prone to falling or being hit, especially in some complex road conditions. For example, mountain bike enthusiasts are prone to falling and being hit. The current headlight housing has poor toughness and fall resistance and is easily damaged by bumps and collisions.

Through the composite structure of the housing body and the rubber ring, when the housing body is deformed by impact, the rubber ring can play an elastic buffering role, thereby improving the overall toughness and drop-resistant performance. The rubber ring is partially exposed from the housing body, and before the housing body is hit by an impact object, the impact object will first hit the rubber ring. The rubber ring itself has elastic buffering properties, thereby further improving the drop-resistant performance, thereby solving the problems raised in the above-mentioned background technology.

[0007] Preferably, the shell body is integrally injection molded.

[0008] Preferably, the longitudinal section of the annular groove is an arc groove that is more than half of a circular arc.

[0009] Preferably, the multiple circles of annular grooves are evenly spaced.

[0010] Preferably, the rubber ring is partially exposed from the shell body.

[0011] Preferably, the rubber ring is a hot melt rubber ring.

[0012] Preferably, the rubber ring is directly hot-melt bonded to the shell body.

[0013] Preferably, the rubber ring is PUR hot melt adhesive.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. Through the composite structure of the shell body and the rubber ring, when the shell body is deformed by impact, the rubber ring can act as an elastic buffer, thereby improving the overall toughness and anti-fall performance.

[0016] 2. The rubber ring is partially exposed from the shell body. Before the shell body is hit by an object, the object will first hit the rubber ring. The rubber ring itself has elastic buffering properties, which further improves the anti-fall performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-5 The utility model provides a high-toughness and drop-resistant injection-molded housing for a vehicle lamp, comprising a housing body 1, wherein the housing body 1 is a cover-type housing, wherein the housing body 1 is provided with a plurality of annular grooves 2 at intervals along its outer wall, wherein each of the annular grooves 2 is sleeved with an apron 3; when in use, through the composite structure of the housing body 1 and the apron 3, when the housing body 1 is deformed by impact, the apron 3 can act as an elastic buffer, and when the housing body 1 is deformed and pulls the apron 3, the apron 3 provides a reverse pulling force to prevent the deformation, and when the housing body 1 is deformed and squeezes the apron 3, an elastic buffer support is provided, thereby improving the overall toughness and drop-resistant performance.

[0025] Specifically, the shell body 1 is integrally injection-molded; in this embodiment, the overall strength of the shell body 1 is improved.

[0026] Specifically, the longitudinal section of the annular groove 2 is an arc groove 4 that is more than half of a circular arc. In this embodiment, the rubber ring 3 is not easy to fall out of the arc groove 4, thereby enhancing its stability on the shell body 1 when it is hit.

[0027] Specifically, the multiple circles of the annular grooves 2 are evenly spaced. In this embodiment, the elastic buffering of the shell body 1 is uniform at various locations, and the overall appearance is more beautiful.

[0028] Specifically, the rubber ring 3 is partially exposed from the shell body 1. In the present embodiment, before the shell body 1 is hit by an impact object, the impact object will first hit the rubber ring 3. The rubber ring 3 itself has elastic buffering properties, thereby improving the anti-fall performance.

[0029] Specifically, the rubber ring 3 is a hot-melt rubber ring; in this embodiment, the rubber ring 3 is conveniently mounted on the shell body 1, and the hot-melt adhesive is applied to the ring groove 2 in one circle by a hot-melt adhesive machine, and the rubber ring 3 is mounted after cooling and forming.

[0030] Specifically, the rubber ring 3 is directly hot-melt bonded to the shell body 1; in this embodiment, the rubber ring 3 is directly bonded to the shell body 1, so that when the shell body 1 is deformed and the rubber ring 3 is pulled, the rubber ring 3 provides a reverse pulling force to prevent its deformation.

[0031] Specifically, the rubber ring 3 is PUR hot melt adhesive. In the present embodiment, the PUR hot melt adhesive has excellent properties such as high temperature resistance, wear resistance, and corrosion resistance, so that the rubber ring 3 itself is not easily damaged, thereby improving the overall strength.

[0032] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0033] Working principle: When in use, through the composite structure of the shell body 1 and the rubber ring 3, when the shell body 1 is deformed by impact, the rubber ring 3 can play an elastic buffering role. When the shell body 1 is deformed and pulls the rubber ring 3, the rubber ring 3 provides a reverse pulling force to prevent its deformation. When the shell body 1 is deformed and squeezes the rubber ring 3, it provides elastic buffering support, thereby improving the overall toughness and anti-fall performance. Since the rubber ring 3 is partially exposed from the shell body 1, before the shell body 1 is hit by an impactor, the impactor will first hit the rubber ring 3. The rubber ring 3 itself has elastic buffering properties, which further improves the anti-fall performance.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
