Description

car sunshade

technical field

The utility model relates to an automobile sunshade device.

Background technique

In summer, after the car is exposed to the sun for a period of time, the steering wheel and seats are scalded by the sun, and the temperature in the cab will rise rapidly, which will accelerate the aging of some plastic parts inside the vehicle, and when the driver enters the cab, the air conditioner will not be able to quickly Cool down, making the driver and passengers feel extremely uncomfortable. In addition, due to the temperature, the higher the temperature, the heavier the unpleasant smell emitted from the interior of the car.

The car sunshade device is a product made to deal with the excessively high temperature of the cockpit inside the car caused by the strong solar radiation in summer. At present, there are many kinds of car sunshade and light-proof devices on the market, each with its own characteristics. Existing automobiles deal with solar radiation mainly by physical shading and mechanical detachable sunshade. Physical sunshade methods include built-in sunshade products, external sunshade products, special light-proof pads, spray-type car cooling agents and solar car sunroofs, etc. However, the design of physical shading methods for anti-solar radiation products is not mature enough. Due to the constraints of the profit-seeking factors of manufacturing companies and the lack of design capabilities, such products usually show unreasonable operation methods and lack of artistic sense of design, resulting in Consumers' evaluation of the product's expected value is in a negative state, which greatly reduces the purchase desire and enthusiasm of buyers.

Someone in the industry has developed a mechanical detachable sunshade device, such as an external car sunshade. The sunshade effect is very good, the price is relatively moderate, and it is more convenient to use. However, since the device is placed outside the car, it is easy to be stolen. The built-in car sun visor has a good sun shading effect, but it is troublesome to operate. Many users often buy this product, but when they get off the car, they often forget to use the product due to time constraints or do not use it due to the complicated operation. The external car cover has a simple structure, but the operation is extremely complicated, and it is not suitable for anti-theft, and it is more complicated to store and release.

Therefore, it is very necessary to design a sunshade device that can open the sunshade when parking (especially in a place where the sun is shining) to reduce the temperature change in the car, and can save the energy consumed by turning on the air conditioner after entering the car. The inventor does further research on this, develops a kind of automobile sunshade device, and this case produces thus.

Utility model content

The technical problem to be solved by the utility model is to provide an automobile sunshade device, which has a good effect of avoiding light and sunshading, is very convenient to use, and has one-button operation.

For solving the problems of the technologies described above, the technical solution of the utility model is:

A car sunshade device, comprising a sunshade curtain, a base and two sets of storage components; the two sets of storage components are respectively fixedly installed on the left and right sides of the base;

The storage components include pulleys, guide wheels, guide rails, wire wheels, half shafts, springs and motors that provide electric energy; the motors are connected to the wire wheels, the wire wheels are connected to the half shafts through pull wires, and the guide rails are fixed and installed on the front windshield of the car in a detachable manner On the glass, the guide wheel is installed on the guide rail in a movable manner. The pulley controlling the movement direction of the cable is set on the top of the guide rail. The bottom of the guide rail, the motor and the wire wheel are all fixed on the base. The other end of the sunshade is connected to the spring; the base placed on the instrument panel has a roller shade cylinder, one end of the sunshade is fixed in the roller shade cylinder, and the other end of the sunshade is fixed on the semi-axis of the storage component;

Wind the cable through the motor-operated wire wheel, and the cable pulls up the half shaft through the pulley, driving the sunshade to move upwards, releases the cable through the motor-operated wire wheel, and the cable goes down the lower half shaft through the pulley, driving the sunshade to move downward.

Further, an electromagnetic clutch is also included, and the electromagnetic clutch is located under the wire wheel and installed on the base.

Further, a suction cup is also included, and the guide rail is fixedly installed on the front windshield of the automobile through the suction cup.

Further, the motor is a stepping motor.

Further, the guide rail is a folding guide rail.

After the above scheme is adopted, when the sunshade needs to be raised, the motor is controlled to rotate in the forward direction so that the wire wheel winds the cable, and the cable pulls up the half shaft through the pulley. The telescopic guide wheel moves upward on the guide rail, thereby driving the sunshade to move upward smoothly; when the sunshade needs to be lowered and stored, the control motor reverses to make the wire pulley release the cable, and the cable goes down the lower half shaft through the pulley. At this time, The guide wheel connected with the half shaft also moves downward together, and the telescopic guide wheel moves downward on the guide rail through the spring, thereby driving the sunshade to move downward steadily and smoothly.

The utility model has the following advantages:

1. Solved the problem of the steering wheel and seats being scalded by the sun. When the driver pulls up the sunshade roller blind, the effect of avoiding light and sunshade is good, and these problems will disappear. At the same time, it can also prevent the car from being exposed to the sun. Fading or even cracking of the instrument panel and aging failure of components;

2. When the driver opens the sunshade, the sunshade has a certain anti-theft function, so that the thief cannot observe the situation inside the car from the front windshield, and avoids the theft of the property inside the car;

3. The utility model can also protect the invisibility of the driver and passengers. When the sunshade is pulled up, the car will feel like being in an opaque small house with a sense of security, and it will be very practical and at ease when doing anything. Prevent others from easily seeing the situation inside the car through the front windshield;

Fourth, the state stipulates that advertising is not allowed on the outside of the car (if you want to advertise, you need to provide an application to the relevant department), and the owner of the car does not allow anyone to advertise on his car. However, there are no regulations in the country inside the car. Since the front windshield is the best advertising position of the vehicle, it is possible to advertise on this device to further improve the economic benefits of this device;

5. This device also has certain environmental protection and energy-saving functions. When the driver enters the vehicle that has just been exposed to the sun, the air conditioner is bound to be turned on. If this device is installed, the energy consumption of the air conditioner can be saved to a certain extent, and formaldehyde can be reduced. release of harmful gases.
