Description

Vehicle lamp structure with multiple waterproof parts

The invention relates to a vehicular lamp structure, in particular to a combination of a lamp holder and a lamp housing, and when the lamp holder is assembled with the lamp housing, the gaps are combined with each other, from the outside to the inside. There is a vehicle luminaire structure in which at least two waterproof members are present.

Generally speaking, the structure of the lamp exposed outside the vehicle is usually provided with a waterproof member to prevent external moisture (such as rain) from infiltrating into the interior of the lamp structure, causing a short circuit in the wire and damaging the lamp. Structure, only the structure of the lamp having the waterproof member is described. Referring to Fig. 1, the lamp structure 1 includes a lamp holder 11 and a lamp housing 13, wherein the lamp holder 11 can be assembled to a vehicle. A first accommodating space 110 is defined in a side of the first accommodating space 110. The blocking portion 112 is extended from the inner wall surface 111 of the socket 11 and has an end. A distance is spaced from the inner wall surface 111 of the socket 11 to divide the first accommodating space 110 into a central accommodating portion 1101 and a surrounding accommodating portion 1103, and a light-emitting element 15 is received into the central accommodating portion. In 1101, it is assembled to the bottom surface of the socket 11 so that after receiving an external power source, a light source can be generated and projected from one side of the socket 11.

As described above, referring to FIG. 1, a waterproof member 17 is made of a resilient plastic material and corresponds to the configuration of the surrounding receiving portion 1103 so as to be positionable to the surrounding receiving portion 1103. a second accommodating space 130 is recessed on one side of the lamp housing 13 . The first accommodating space 110 and the second accommodating case are assembled in the case where the lamp housing 13 is assembled with the lamp holder 11 . The space 130 is in communication, and the periphery of the lamp housing 13 extends into the surrounding receiving portion 1103 and abuts against the waterproof member 17, and the outer wall of the lamp housing 13 corresponds to one of the lamp holders 11 The outer peripheral portion of the lamp holder 11 is placed against the periphery of one side of the lamp holder 11 when the lamp housing 13 is assembled with the lamp holder 11 at the position of the side periphery. The barrier function of the waterproof member 17 prevents the outside water from passing through the gap between the socket 11 and the lamp housing 13 and penetrates into the center housing portion 1101, thereby dampening the circuit board of the light-emitting element 15 The luminaire structure 1 is damaged.

However, as shown in Fig. 1, the above-mentioned lamp structure 1 is still not perfect in waterproofing effect, and cannot achieve the high waterproof effect expected by the manufacturer or the consumer. The main reason is that the lamp holder 11 and the lamp are Between the shells 13, the two are fixed by screwing, so that, in the position adjacent to the screw, the side edge of one side of the socket 11 and the lamp housing 13 are affected by the pressing force of the screw. The outer cover portion 132 will be tightly fitted, but at a position away from the screw, since the pressing force of the screw is small, and the waterproof member 17 itself has an elastic restoring force, the lamp housing 13 is A peripheral force is generated to cause a gap L between the socket 11 and the lamp housing 13 to cause the outside water to accumulate in the peripheral housing portion 1103 through the spacing L (as in the virtual circle A of FIG. 2). Moreover, as the vehicle structure 1 is greatly vibrated due to the influence of bumps, the periphery of the lamp housing 13 and the waterproof member 17 often shift in an instant, so that the original accumulation is The water here can penetrate into the gap Receiving position (e.g., FIG. 2 of the imaginary circle A) surrounding the receiving portion 1103 adjacent the center 1101 thus can flow into the central receiving portion 1101, causing the light emitting element 15 from being damaged due to short circuit.

In addition to the foregoing reasons, as shown in Figures 1 and 3, since the luminaire structure 1 is assembled to the outside of the vehicle, it will cause its own temperature rise after a long period of exposure to the sun, due to the lamp holder. 11 is usually made of a plastic material, so in the case of high temperature, it is easy to soften and deform. Although the waterproof member 17 itself has elasticity, it is limited by the volume and the restoring force to be maintained, so that the waterproof member 17 and A gap (such as the virtual circle C in FIG. 3) is formed between the inner wall surfaces 111 of the socket 11, so that when the lamp structure 1 is greatly shaken due to the influence of the bump, the external water can be infiltrated. Into the gap, and then infiltrated into the central receiving portion 1101, causing damage to the lamp structure 1. In addition, if the waterproof member 17 or the lamp holder 11 is produced, the surface is slightly uneven due to poor production. When the lamp structure 1 is used for a long period of time, the waterproof member 17 is easily fatigued or the lamp holder 11 is deformed, resulting in a change as shown in FIG.

In summary, the waterproof effect of the traditional luminaire structure is not as expected by the industry and consumers, not only causing consumers to spend extra money to repair or replace the luminaire structure, but also affect the brand loyalty of the consumer to the industry. Therefore, how to design a luminaire structure that can solve the above problems is an important issue that many manufacturers have solved.

In view of the fact that when the vehicle is on the way, or when the vehicle is exposed to the sun for a long time, the waterproof effect of the traditional luminaire structure is greatly reduced, so that the external water can penetrate into the luminaire structure, resulting in structural damage of the luminaire, and then derivative The inventor has finally developed and designed a vehicular lamp structure having multiple waterproof members of the present invention after long-term efforts and research, in order to effectively solve the above problems by the present invention.

An object of the present invention is to provide a vehicular lamp structure having multiple waterproof members, mainly by providing a plurality of waterproof members on the vehicular lamp structure to enhance the waterproof effect of the vehicular lamp structure. The lamp structure comprises a lamp holder, a light-emitting component, a plurality of waterproof components and a lamp housing, wherein the lamp holder is assembled to a vehicle, and a first receiving space is recessed on one side thereof, the first receiving The space ring is provided with a blocking portion, one end edge of the blocking portion is connected to the lamp holder, and the first receiving space is divided into a central receiving portion and a surrounding receiving portion, and the light emitting element is received into the central receiving portion. And receiving an external power source, wherein a waterproof member is positioned to the bottom surface of the surrounding receiving portion, and the lamp housing is provided with a second receiving space and a joint portion, and the joint portion can extend into the periphery In the accommodating portion, and closely abutting the waterproof member, the lamp housing can be fixedly assembled to the lamp holder, and the remaining waterproof members are clamped between the lamp holder and the gap of the lamp housing, so that Can ensure the lamp holder and lamp housing During assembly, at least two waterproof members are present from the outside to the inside, so that the vehicle lighting structure is prevented from being affected by bumps due to bumps during long-term exposure or during vehicle travel. Infiltrating into the position of the light-emitting element, thereby causing damage to the structure of the vehicle lamp.
