Description

Technical Field

[0001] The utility model relates to a fixing device, in particular to a device used for connecting and fixing lamps on vehicles. Background Art

[0002] For the safety of nighttime driving, headlights are required to be installed at the front of the vehicle to provide lighting when driving at night. On the front side of the vehicle, the rear of the lamp is the engine room, in which the vehicle's power mechanism is often installed. The front fender and front hood at the front of the vehicle provide a relatively closed environment for these power mechanisms to protect the power mechanisms from erosion by rain from the outside. The front hood and front fender are formed with arc-shaped portions that bend toward the direction of the lamp at the position of the lamp. After the lamp is assembled in place, these arc-shaped portions are buckled onto the outer surface of the lamp housing. In order to prevent leakage, it is generally required to provide an elastic pad made of rubber material on the outer peripheral surface of the lamp housing at the position corresponding to the front hood and front fender, and liquid sealing is achieved by the fit and abutment between the front hood and front fender and the elastic pad.

[0003] A Chinese patent document (publication number: CN 205956985U) discloses a desiccant fixing device, including a lamp body with a through hole, and a mounting seat fixed on the lamp body and embedded in the through hole, and a replaceable desiccant is arranged on the mounting seat. With such a configuration, when the desiccant needs to be replaced, the operator removes the mounting seat from the lamp body through the through hole, removes the desiccant from the mounting seat, and replaces it with a new desiccant, thereby achieving easy replacement of the desiccant and preventing the vehicle lamp from fogging due to desiccant failure. The utility model also provides a lamp having the above-mentioned desiccant fixing device and a vehicle having the lamp.

[0004] This fixing device discloses a fixing structure that can realize the fixed connection of the lamp. When fixing the lamp, it is also necessary to set the above-mentioned elastic pad. The setting of this elastic pad is inconvenient. After a long time of use, it is easy to have gaps due to aging. It cannot well meet the waterproof requirements of the vehicle during the rainy day. Rainwater is easy to penetrate into the cabin from the position of the lamp housing and cause damage to the power mechanism. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a vehicle lamp connection and fixing device, which can fix the lamp and has good waterproof performance at the position of the lamp on the vehicle.

[0006] In order to solve the above technical problems, the technical solution of the utility model is: a vehicle lamp connection and fixing device, the front fender and the front hood are used to wrap around the outer periphery of the lamp housing, and is characterized in that an outward convex ring is provided at the outer edge of the inner end of the lamp housing, and the convex ring extends along the entire outer edge of the inner end of the lamp housing; a protruding baffle body is provided on the surface of the convex ring facing the outer end of the lamp housing, and the baffle body is strip-shaped, and there is a gap between the baffle body and the side of the lamp housing, so as to form a guide port between the baffle body and the lamp housing; an arc-shaped portion extending toward the lamp housing is formed at the end of the front fender and the front hood facing the lamp housing, and the inner surface of the arc-shaped portion is in contact with the baffle body.

[0007] After the lamp is assembled, the curved parts on the front hood and the front fender are fitted onto the baffle. Even if there is a small gap between the front hood, the front fender and the lamp housing, when the vehicle is speeding in the rain, a small amount of rainwater that penetrates will be blocked by the baffle and will only accumulate in the guide port.

[0008] Furthermore, the blocking body extends on the convex ring along the circumferential direction of the inner end of the lamp housing, which well meets the requirement of the blocking body for blocking rainwater, and the blocking body can stably block rainwater.

[0009] Furthermore, the two ends of the baffle body are formed with curved parts, which are connected to the side of the lamp housing as a whole, and the periphery of the diversion port is closed. This is conducive to the baffle body to effectively intercept the infiltrated rainwater, so as to prevent the rainwater entering the diversion port from continuing to spread deeper due to pressure accumulation.

[0010] Furthermore, there are two stoppers, which are respectively fitted with the arc-shaped parts on the front bonnet and the front fender, which is well adapted to the respective contact sealing of the front bonnet and the front fender, and can achieve the installation and matching requirements of the front bonnet and the front fender while ensuring the sealing effect.

[0011] Furthermore, the front bonnet and the front fender are respectively formed with notches adapted to the outer side of the lamp housing, and the size of the notches corresponds to the size of the corresponding blocking body. The provision of the notches can ensure that the front bonnet and the front fender are closely matched with the lamp housing.

[0012] Furthermore, an inlay is provided on the surface of the convex ring facing the outer end of the lamp housing, and the inlay is separated from the blocking body. The inlay is formed by a protrusion integrally formed on the lamp housing, and the inlay is provided to facilitate the corresponding structures on the back of the front hood and the front fender to be plugged and matched with the inlay, thereby improving the stability of the lamp on the vehicle.

[0013] Compared with the prior art, the utility model has the following beneficial effects: a convex ring is provided on the lamp housing, and the blocking body is provided on the convex ring. Through the combination of the convex ring and the blocking body, a sealing structure with good sealing effect can be formed on the lamp housing, which can effectively prevent rainwater and dust from entering the cabin from the gap between the lamp housing and the front hood and the front fender. The sealing effect is good, and effective protection can be provided for the power mechanism in the cabin. Even if a small amount of rainwater penetrates from the side of the lamp housing, it will be accumulated by the diversion port, and the deep penetration of rainwater can be prevented. By setting the side of the lamp housing in an inclined manner, the rainwater accumulated in the diversion port will also seep out along the side of the lamp housing after parking, thereby having a good protection effect on the power mechanism.
