Description

Car sun protection device

The present invention relates to an automobile device, and more particularly to an automobile sun protection device.

When the car is parked under the scorching sun, the car will continue to receive the radiant heat of the sun, and when the space inside the car is sealed, it is difficult to dissipate heat by the heat convection, so that the owner wants to enter the space inside the car. When driving, you must feel very uncomfortable due to the heat accumulated in the car. Therefore, automobiles usually attach thermal insulation paper to the glass to reduce the radiant heat transmitted by the sunlight to the interior space of the vehicle by means of reflection. However, since sunlight is a light composed of light of a plurality of wavelengths, it is difficult to completely reflect light of all wavelengths in order to maintain a certain degree of light transmission of the glass, so that in the case where only part of the sunlight is reflected, it is long. After the time exposure, a large amount of radiant heat will still be transmitted to the interior space, and the effect of generating heat insulation is rather limited.

Referring to Fig. 1, a conventional automotive thermal insulation device 1 is suitable for mounting on a vehicle 2 having a plurality of glasses 21 and includes a plurality of thermal insulation mats 11 respectively detachably disposed on the glass 21. The insulating mats 11 can block most of the sunlight and do not affect the transmittance of the glass 21 after disassembly. However, when the thermal insulation mats 11 are provided, it is necessary to dispose each of the thermal insulation mats 11 on the corresponding glass 21 one by one, which is cumbersome in the installation steps, so that the disadvantages in use are still to be improved. In addition, since the influence of the sunlight on the automobile 2 is not only the radiant heat radiated from the glass 21 to the inside of the vehicle, but also the thermal energy directly transmitted from the sheet metal of the automobile 2 to the interior of the vehicle, the automobile compartment is separated. The thermal insulation effect of the thermal device 1 is still not satisfactory.

Therefore, the object of the present invention is to provide a car sun protection device with good heat insulation effect and convenient installation.

Therefore, in the novel sunscreen insulation device of the automobile, the automobile comprises two end edges respectively located at the front end and the rear end, and a sheet metal plate extending between the end edges and extending forward and backward. The vehicle sun protection device comprises a housing mounted on one end of the vehicle and surrounding an accommodation space, a rail unit mounted on the sheet metal of the automobile, and a housing disposed on the housing. Occlusion unit in space.

The track unit includes two tracks spaced apart from each other and extending in the same direction; and the shielding unit includes a shielding cloth having a fixed end and a moving end respectively located at opposite ends, and a moving end connected to the shielding cloth and disposed on the track Moving components on the orbit.

The fixed end of the shielding cloth is located in the accommodating space, and the moving member can move along the extending direction of the tracks, and the moving ends of the shielding cloth are moved together to make the shielding cloth along the tracks. Extend the direction and spread it on the sheet metal of the car.

The effect of the present invention is that by moving the moving member on the tracks, the shielding cloth can be spread on the sheet metal of the automobile in a simple step, and the shielding cloth completely shields the top end of the automobile. The solar light is blocked above the car to prevent the heat energy of the sun from being transmitted to the interior space of the car, so that a good heat insulation effect can be achieved.

Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same reference numerals.

Referring to FIG. 2 and FIG. 3, a first embodiment of the novel sunscreen insulation device 3 of the present invention is suitable for being mounted on a car 9, which comprises two end edges 91 respectively located at the front end and the rear end, and an interface A sheet metal plate 92 extending between the end edges 91 and extending forward and backward.

The track unit 32 includes two tracks 321 which are spaced apart from each other and extend in the same direction. The shielding unit 33 includes a shielding cloth 331 having a fixed end 301 and a moving end 302 respectively at opposite ends, and a shielding cloth 331 connected to the shielding cloth 331. The moving member 302 and the moving member 332 disposed on the rails 321 and a shaft 333 pivotally disposed in the receiving space 310 of the housing 31. The fixed end 301 of the shielding cloth 331 is located in the accommodating space 310 and is fixed on the shaft 333. The shielding cloth 331 is wound around the shaft 333 to facilitate storage of the shielding cloth 331 sufficient to block the automobile 9 in the accommodating space 310 where space is limited.

Referring to FIG. 4 and FIG. 2 and FIG. 3, the driving unit 34 is preferably a stepping motor and is electrically connected to the moving member 332 for driving the moving member 332 along the track 321 of the track unit 32. mobile. It should be noted that the power supplied to the driving unit 34 can be directly connected to the existing battery of the automobile 9 (not shown), or the power module can be additionally provided. Due to the technical features of this part, those skilled in the relevant art can change the designer according to the requirements, and therefore will not be further described herein.

Referring back to FIG. 2 and FIG. 3, when the first embodiment is used, the driving unit 34 can be activated by a remote control or a physical button or the like to move the moving member 332 along the extending direction of the tracks 321 . The moving end 302 of the shielding cloth 331 is moved together, and the shielding cloth 331 is spread on the sheet metal 92 of the automobile 9 along the extending direction of the rails 321 in a simple step to block the upper portion of the automobile 9. By shielding the sunlight by the shielding cloth 331, heat energy can be prevented from being radiated or transmitted to the inside of the automobile 9 at the same time, so that a good heat insulation effect can be produced.

Referring to FIG. 5 , the shielding unit 33 further includes a rewinding elastic piece 334 connected between the shielding cloth 331 and the shaft 333 , so that the shielding cloth 331 can be smoothly re-accommodated on the shaft 333 . The retractable elastic piece 334 can accumulate an elastic restoring force when the shielding cloth 331 is carried out from the shaft 333, and the elastic restoring force can be generated when the shielding cloth 331 is rewinded on the shaft 333. The assistance of the direction makes the storage of the shielding cloth 331 smoother.

It should be particularly noted that the car 9 as shown in FIGS. 2 and 3 is usually provided with a bumper for safety reasons. If the appearance of the casing 31 of the first embodiment is more integrated with the automobile, the housing 31 can be integrally formed with the bumper of the automobile 9 except that the casing can be avoided. The body 31 occupies a space and also allows the appearance of the car 9 to present an integrated visual effect.
