Description

Frameless automatic rain shelter

Technical Field

The utility model relates to an automatic canopy of no skeleton.

Background

In order to prevent rainwater from wetting clothes, many families install a fixed canopy, and the clothes are shielded no matter whether the weather is clear or overcast and rainy, so that the lighting requirement of the clothes cannot be met, and therefore the automatic canopy capable of sensing rainwater to automatically expand is needed.

At present common non-fixed rainshelter has manual and electric remote control rainshelter, and the structure adopts folding telescopic, mostly is parking rainshelter, and its structure contains large-scale metal support in order flexible, and skeleton volume and quality are great, need great power motor or manual operation just can stretch out and draw back, and the cost is higher and can't satisfy unmanned automatic demand that expandes when raining, is not suitable for and shines clothes rainshelter.

Disclosure of Invention

The utility model aims at overcoming not enough among the prior art, providing a no skeleton automatic canopy realizes that the canopy can sense the rainwater and expand automatically under the unmanned condition, automatic shrink when no rain.

In order to solve the technical problem, the utility model discloses a following technical scheme realizes:

a frameless automatic rain shelter comprises a rain shelter body and a control module, wherein the rain shelter body comprises four upright posts, two cross rods, a scroll, connecting rods and rain shielding cloth, every two upright posts and one cross rod form a frame shaped like a Chinese character 'men', one end of the rain shielding cloth is connected with the scroll, the other end of the rain shielding cloth is connected with the connecting rods, the inner sides of the two cross rods are provided with annular chains, two ends of a rotating shaft are provided with chain wheels, the chain wheels are meshed with the chains, the rotating shaft is rotatably arranged at one end of the cross rods through bearings, and the rain shielding cloth is positioned between the two cross rods; two ends of the connecting rod are respectively and fixedly connected with the chains at the corresponding sides, and a motor is fixed on the cross rod and drives the rotating shaft to rotate;

the control module comprises a controller and a rainwater sensor, the rainwater sensor is arranged at one end, far away from the rotating shaft, of the cross rod, and the rainwater sensor and the motor are electrically connected with the controller.

When the rain sensor detects rain, the controller controls the motor to rotate forwards to drive the scroll to rotate, the chain wheel drives the chain to rotate, the chain drives the connecting rod to move towards one end far away from the scroll, and then the rain shielding cloth is opened; when the rain stops, the controller controls the motor to rotate reversely, the reel is driven to rotate reversely, the chain wheel drives the chain to rotate, the chain drives the connecting rod to move towards one end close to the reel, and then the rain shielding cloth is folded. The rain-proof cloth can be automatically opened and closed, and the operation is convenient. Compare with the foldable rainshelter of tradition, the utility model discloses overall structure is light and handy, easily preparation and installation utilize low-power motor to drive the operation, can expand automatically when raining, and automatic shrink when no rain has satisfied the dual demand that clothing was taken shelter from rain and daylighting under the unmanned condition.

In a further improvement, the motor is a servo motor.

Further improve, two pole settings height that keep away from the spool are less than two pole settings near the spool, make the rain-proof cloth of opening be the slope form, prevent that the rainwater from gathering on the rain-proof cloth.

Further improve, the inboard of horizontal pole is seted up flutedly along its length direction, and the chain setting prevents that the chain from droing in the recess.

The vertical rods and the cross rods are made of stainless steel materials, so that the vertical rods and the cross rods are not rusted, and the service life is prolonged.

Compared with the prior art, the beneficial effects of the utility model are that:

this automatic canopy of no skeleton has got rid of a large amount of member and pulley structure among the foldable canopy of tradition for preparation and equipment are more light and handy simple and easy, and the cost is reduced has sufficient stability simultaneously.

When the rain sensor detects rain, the controller controls the motor to rotate forwards to drive the scroll to rotate, the chain wheel drives the chain to rotate, the chain drives the connecting rod to move towards one end far away from the scroll, and then the rain shielding cloth is opened; when the rain stops, the controller controls the motor to rotate reversely, the reel is driven to rotate reversely, the chain wheel drives the chain to rotate, the chain drives the connecting rod to move towards one end close to the reel, and then the rain shielding cloth is folded. The rain-proof cloth can be automatically opened and closed, and the operation is convenient.

Drawings

Fig. 1 is a schematic structural view of the frameless automatic canopy of the present invention.

Detailed Description

The invention will be described in further detail with reference to the following detailed description and accompanying drawings:

as shown in fig. 1, a frameless automatic canopy comprises a canopy body and a control module, wherein the canopy body comprises four upright posts 1, two cross rods 2, a scroll 3, a connecting rod 4 and a canopy 5, each two upright posts and one cross rod form a frame shaped like a Chinese character 'men', one end of the canopy is connected with the scroll, the other end of the canopy is connected with the connecting rod, annular chains are arranged on the inner sides of the two cross rods, chain wheels are arranged at two ends of a rotating shaft, the chain wheels are meshed with the chains, the rotating shaft is rotatably arranged at one end of the cross rod through a bearing, and the canopy is positioned between the two cross rods; two ends of the connecting rod are respectively and fixedly connected with the chains at the corresponding sides, and a motor is fixed on the cross rod and drives the rotating shaft to rotate;

In this embodiment, the motor is a servo motor.

In this embodiment, the height of the two vertical rods far away from the reel 3 is smaller than that of the two vertical rods close to the reel, so that the opened rain-proof cloth is inclined, and rainwater is prevented from gathering on the rain-proof cloth.

In this embodiment, the recess has been seted up along its length direction to the inboard of horizontal pole 2, and the chain setting prevents that the chain from droing in the recess.

In this embodiment, the vertical rod 1 and the cross rod 2 are made of stainless steel, so that the vertical rod and the cross rod are not rusted, and the service life is prolonged.

The unexplained parts related to the present invention are the same as or implemented by using the prior art.
