Description

Housing with temperature control and heat preservation functions and headlight housing thereof

A multi-layered accessory, particularly a housing with temperature control and heat preservation functions and its headlight housing.

In colder regions, harsh climates can easily cause ice or frost to form on car and motorcycle headlights, which not only affects the lighting efficiency of the headlights, but also affects the driver's vision and driving safety. In extremely cold climates, headlights made of different materials have different shrinkage forces when facing low temperatures, causing the headlight components to fall off or shift when facing extremely low temperatures, making the headlights unusable.

Most of the deicing and defrosting methods currently used are physical or chemical deicing methods such as plastic scrapers or spray-type deicers, but the above methods are short-term practices. In addition to being unable to effectively deicer and defrost for a long time, they also cause waste of environmental resources. In view of this, there is an urgent need for a plastic shell that can have both heat preservation and temperature control effects and can be used for car and motorcycle headlights for a long time.

In order to reduce the problem of the lamp components falling off or shifting under low temperature conditions and improve the problems mentioned in the previous technology of this specification, the new invention provides a shell with temperature control and heat preservation functions, including a protective layer stacked in sequence, which is a transparent material with dielectric properties; a bonding layer, which is a transparent adhesive material with dielectric properties and flexibility. The bonding layer is relatively One side of the layer is concavely provided with an insulating pattern; a conductive layer, which is a kind of adhesive material with electrothermal properties, when the bonding layer and the conductive layer are correspondingly combined, the bonding layer completely covers the conductive layer; a temperature control and heat insulation layer, which is a kind of carbon-containing conductive adhesive material and can control the temperature within a specific range; and an insulating layer, which serves as a protective structure and covers the combined surface of the bonding layer and the conductive layer.

Among them, the material of the protective layer includes polycarbonate (PC).

The conductive layer includes a conductive adhesive material, and the conductive layer is processed on the connecting layer by coating.

The next layer is a film or liquid colloid, and is processed on the protective layer by screen printing, coating, pad printing, transfer printing, transfer printing, in-mold printing, 3D printing, inkjet printing, and gravure printing.

Among them, the conductive glue material is a material with high conductivity such as silver, copper, gold, and aluminum.

Among them, the material of the temperature control and insulation layer includes carbon-containing conductive glue.

Among them, the carbon-containing conductive adhesive material is a metal carbide produced by mixing high-conductivity metal materials such as silver, copper, gold, and aluminum with carbon-based materials.

The bonding layer material is optical clear adhesive.

The shell material with temperature control and heat preservation function provided by the new model is simple and convenient to manufacture, and can be widely used in different materials and products. The conductive layer directly generates electrothermal properties after being energized, so that the shell with temperature control and heat preservation function can quickly and efficiently produce temperature control and heat preservation effects, and achieve the effect of deicing and defrosting. The conductive layer is coated on the bonding layer in a colloid manner, so that any part of the temperature control and heat preservation shell can produce uniform and equal heat preservation and temperature control effects, and will no longer heat up when a specific temperature is reached.

As shown in FIG. 1 and FIG. 2 , the shell with temperature control and heat preservation function provided by the invention is a protective layer 10, a connecting layer 20, a conductive layer 30, a temperature control and heat preservation layer 40 and an insulating layer 50 stacked in sequence. The shell can be heated to a fixed temperature range after being electrically conductive to produce temperature control and heat preservation effects. It is suitable for making workpieces for transport vehicles, lamp covers, traffic signs, lenses, snow mirrors, signal sensors, display panels or mirrors and other daily necessities. Among them, the protective layer 10 is a transparent material with dielectric properties, which can be plastic. Preferably, the protective layer 10 is made of plastic materials such as polycarbonate (PC), polypropylene (PP), or polyethylene (PE). Furthermore, the protective layer 10 is a resilient film to effectively reduce the overall thickness.

Furthermore, as shown in FIG3 , the housing with temperature control and heat preservation functions can be applied to the lamp housing of a vehicle such as a car or a motorcycle to produce a vehicle lamp housing A with temperature control and heat preservation functions, so as to overcome the problem that the lamp component B of the current vehicle may fall off or shift when facing extremely low temperatures.

The bonding layer 20 is a transparent adhesive material, which is used to closely bond the protective layer 10 and the conductive layer 30. The bonding layer 20 has dielectric properties and flexibility, and its material is preferably optical adhesive (Optical Clear Adhesive). The type of the bonding layer 20 is not limited. The bonding layer 20 can be selected as a film or liquid adhesive according to the material of the protective layer 10, and can be processed on the protective layer 10 by screen printing, coating, pad printing, transfer, transfer printing, in-mold printing, 3D printing, inkjet printing, gravure printing, etc.

In this embodiment, the bonding layer 20 is liquid, and its overall area is slightly larger than the conductive layer 30 and the temperature-controlling and heat-insulating layer 40. When the bonding layer 20 is correspondingly combined with the conductive layer 30 and the temperature-controlling and heat-insulating layer 40, the bonding layer 20 completely covers the conductive layer 30 and the temperature-controlling and heat-insulating layer 40. The connecting layer 20 is provided with an insulating pattern 21 on one side surface corresponding to the conductive layer 30. The purpose of the insulating pattern 21 is to prevent the conductive layer 30 and the temperature control and insulation layer 40 from being connected to the protective layer 10 after being energized. The type of the insulating pattern 21 is not limited. The area and position of the insulating pattern 21 on the connecting layer 20 are determined according to the conductive layer impedance, conductive position and shape of the finished product.

The conductive layer 30 is a kind of plastic material with electrothermal properties. When powered, it can generate temperature to achieve the effect of deicing and defrosting. The conductive layer 30 has an impedance value between 5Ω and 20Ω. The conductive layer 30 can be a conductive plastic material. Preferably, the conductive plastic material can be a material with high conductivity such as silver, copper, gold, aluminum or carbon.

The temperature control and heat preservation layer 40 is a carbon-containing conductive adhesive with electrothermal properties. When powered on, it can generate temperature and maintain the overall temperature of the headlight component B within a specific range to prevent the temperature of the conductive layer 30 from continuously rising and damaging the headlight component B, and achieve temperature control and heat preservation effects; wherein the temperature in the specific range is between 60°C and 70°C. Preferably, the carbon-containing conductive adhesive can be a metal carbide produced by mixing high-conductivity metal materials such as silver, copper, gold, and aluminum with carbon-based materials such as graphene and nano-carbon tubes. More preferably, the temperature control and heat insulation layer can be a metal conductive layer plus a carbon conductive layer, the metal conductive layer includes a high conductive metal material, the carbon conductive layer includes a carbon-based material, the carbon conductive layer is fully connected to and covers the metal conductive layer, and the ratio of the metal conductive layer to the carbon conductive layer is 1:1 to 1:1.2 (high conductive metal material: carbon-based material); the temperature control and heat insulation layer can also be a mixture of the high conductive metal material and the carbon-based material uniformly mixed and then mixed with other metal carbides, such as a silver-carbon-nickel-carbon conductive glue produced by mixing a silver-carbon conductive glue with a nickel-carbon conductive glue. It is worth noting that, because the carbon-containing conductive plastic material contains the characteristics of the carbon-based material, even when the high-conductivity metal material is added to the carbon-containing conductive plastic material, the temperature can be maintained within the specific range, thereby preventing the temperature of the headlight component B from being too high.

The conductive layer 30 and the temperature control and insulation layer 40 are sequentially coated on the bonding layer 20.

As shown in Figures 1 and 2, the insulating layer 50 is used as a protective layer to cover the combined surface of the connecting layer 20, the conductive layer 30 and the temperature control and insulation layer 40 to isolate the external environment, so as to prevent the housing with temperature control and insulation functions from being affected by temperature and humidity, and to increase the stability of the conductive layer 30 and the temperature control and insulation layer 40.

Furthermore, the housing with temperature control and heat preservation functions is connected to a power supply device through the conductive layer 30 and the temperature control and heat preservation layer 40, so that the conductive layer 30 and the temperature control and heat preservation layer 40 can generate electrothermal characteristics after being powered. The power supply device can be presented in the form of a battery or connected to a socket. Preferably, the power supply device can provide power in the form of alternating current or direct current.

When the shell with temperature control and heat preservation function is used as the headlight shell A, the edge of the protective layer 10 may extend a snap-fit structure 11 and a lamp holder 60 to be combined with each other, so that the temperature control and heat preservation shell and the lamp holder 60 are formed to place the headlight B. When the headlight B is powered on, the headlight B emits a light that passes through the headlight shell A. Preferably, the conductive layer 30, the temperature control and heat preservation layer 40 and the headlight B of the headlight shell A can be powered on at the same time to ensure that the headlight of the vehicle can automatically have the temperature control and heat preservation function when it is turned on.

The shell material with temperature control and heat preservation function provided by the present invention is simple and convenient to manufacture. When the lamp shell A with temperature control and heat preservation function is manufactured, the conductive layer 30 and the temperature control and heat preservation layer 40 are energized to directly generate electrothermal properties, so that the defogging accessory can quickly and efficiently produce the temperature control and heat preservation function. The conductive layer 30 and the temperature control and heat preservation layer 40 are sequentially coated on the bonding layer 20 in a colloid manner, so that any part of the defogging accessory can produce uniform and equal temperature control and heat preservation effects.
