Description

An automobile front windshield sun insulation curtain device

technical field

The utility model relates to an automobile accessory, in particular to an automobile front windshield sun insulation curtain device.

Background technique

Nowadays, the number of cars owned by residents is increasing, but due to the lack of parking spaces, people can only park their vehicles in the open air when they drive. Such parts are prone to premature aging. At present, there are separate products such as automotive heat insulation curtains on the market, but the quality is uneven and it is not very convenient to use. If the car manufacturer proceeds from the actual use, it should be considered at the beginning of the car design. The realization of automobile heat insulation and sunshade functions provides customers with better choices. The Chinese patent literature discloses a patent for a "automobile front windshield protective cover". Its authorized announcement number is CN 201670090 U, and the authorized announcement date is December 15, 2010. : The cover body is made of waterproof material. The two ends of the middle part of the cover body have elastic rearview mirror protective covers. There are elastic belts above and below the elastic rearview mirror protective cover. The elastic belts are respectively connected to the windproof hook and the anti-theft buckle. The cover body is Isosceles trapezoid; when in use, put the car front windshield protective cover on the outside of the car front windshield, the elastic rearview mirror protective cover is covered on the car rearview mirror, the windproof hook is hooked on the car body, and the anti-theft buckle extends into the car door and buckles each other Live, the front windshield shield of the whole car plays the role of blocking sunlight and so on. The "automobile front windshield protective cover" patent described above provides a kind of protective cover that can be used for the sunshade of the automobile front windshield protective cover, but this protective cover is a kind of independent product, not only will take up more space on the storage, but it is also difficult to use. It is inconvenient. It needs to be taken out and spread out on the front windshield of the car every time it is used. After use, it must be collected and folded and put away. For short-term parking, it will undoubtedly waste more time to use this protective cover.

Utility model content

The utility model aims at overcoming the problem that the automobile front windshield in the prior art lacks a sunshade curtain which is easy to use and convenient to store, and provides an automobile front windshield sunscreen device which can be configured with the car, is simple to operate, and is easy to store.

In order to achieve the above object, the utility model adopts the following technical solutions: a car front windshield sun-insulating curtain device, including a sunshade, and also includes a rotating shaft mechanism, a first traction mechanism, and a second traction mechanism, and the rotating shaft mechanism is provided with a reel . A reel box, the reel is located in the reel box and is rotatably connected with the reel box, and at least one torsion spring is arranged on the reel, and the sunshade is connected with the reel and can be accommodated in the reel box. The first traction mechanism and the second traction mechanism are respectively arranged at two ends of the reel box, and the first traction mechanism and the second traction mechanism are all provided with a traction motor, a traction rope, and a guide column, and one end of the guide column is connected with the reel box, The other end of the guide column is connected with the traction motor, and the traction cables are respectively connected with the traction motor and the sunshade curtain, and the traction motor is synchronously running. To avoid premature aging of car interior panels, instrument panels and other components exposed to the sun, you can use sunshade curtains to block direct sunlight. In a reel box, in order to reduce space occupation, the reel box can be set at the junction of the car dashboard and the front windshield glass. The first traction mechanism and the second traction mechanism, the first traction mechanism and the second traction mechanism all include a traction motor, a traction cable, and a guide column, wherein the guide column is arranged along the front windshield column, and one end of the guide column is connected to the front windshield column. The reel box is connected, and the other end is connected with the traction motor. The sunshade curtain can be automatically lifted by using the traction motor. The traction motor and the sunshade curtain are connected and driven by a traction cable.

Preferably, two torsion springs are arranged symmetrically on the reel. The rotation of the reel and the sunshade itself will generate surface tension on the sunshade. If the surface tension is too small, the sunshade will become soft after being raised, affecting the sunshade area, and the soft sunshade is not easy to store neatly when it is recycled. Install torsion springs at both ends of the reel to provide additional surface tension for the sunshade and eliminate adverse effects.

Preferably, the guide column is provided with a chute, and a roller is provided in the chute, and the roller is connected to the sunshade as a shaft. The lifting path of the sunshade is limited by the guide column. Fix two rollers on the sunshade, and use the rollers to roll in the chute of the guide column, which can reduce the friction between the sunshade and the guide column, and can better Limit the lifting path of the sunshade.

Preferably, the traction cable is a synchronous belt. Compared with the ordinary belt drive, the synchronous belt transmission has the characteristics of accurate transmission and not easy to slip. Using the synchronous belt as the traction cable can make the lifting and lowering of the sunshade more stable and reliable.

Therefore, the utility model has the following beneficial effects: (1) It can be configured with the vehicle and has a simple structure; (2) It is easy to operate and convenient to store.
