When the temperature inside the vehicle is higher than the first temperature threshold and / or the temperature outside the vehicle is higher than the second temperature threshold, the vent at the bottom of the roof additional component can be controlled by the control component to be in an open state, and when the temperature inside the vehicle is lower than or equal to the first temperature threshold and the temperature outside the vehicle is lower than or equal to the second temperature threshold, the vent at the bottom of the roof additional component can be controlled by the control component to be in a closed state.

[0019] In the embodiment of the present invention, the control component can control the in-vehicle vent to be in an open state or a closed state. When the temperature inside the vehicle is higher than a first temperature threshold and / or the temperature outside the vehicle is higher than a second temperature threshold, the control component can control the in-vehicle vent to be in an open state, and when the temperature inside the vehicle is lower than or equal to the first temperature threshold and the temperature outside the vehicle is lower than or equal to the second temperature threshold, the control component can control the in-vehicle vent to be in a closed state.

[0020] In an embodiment of the present invention, when the temperature inside the vehicle is lower than or equal to a first temperature threshold and the temperature outside the vehicle is lower than or equal to a second temperature threshold, the roof attachment component of the vehicle roof is in an unextended state.

[0021] When the temperature inside the vehicle is higher than a first temperature threshold and / or the temperature outside the vehicle is higher than a second temperature threshold, the roof attachment component is controlled to change from the non-extended state to the extended state.

[0022] It should be noted that when the roof additional component of the vehicle roof is in an unextended state, the vents arranged at the bottom of the roof additional component will not be exposed to the air, and no air will enter the roof additional component through the vents arranged at the bottom of the roof additional component.

[0023] refer to Figure 1 , Figure 1 It is a schematic diagram of the components inside the vehicle and the roof.

[0024] Figure 1 The vehicle roof 1, the control component 3, the first temperature sensor 4 for detecting the temperature inside the vehicle, the exhaust outlet 6, the shielding assembly 9, and the exhaust fan 15 are shown. The exhaust outlet 6 may be at the bottom of the vehicle, and the exhaust fan 15 is provided at one end of the exhaust outlet 6 close to the outside of the vehicle.

[0025] Figure 2 is a schematic diagram of the roof and roof attachment parts.

[0026] Figure 2 Two retractable roof attachment parts, namely a roof attachment part 21 , a roof attachment part 22 are shown. Figure 2 Also shown are a two-way cylinder 23 and a support rod 13. Both the two-way cylinder 23 and the support rod 13 are inside the roof 1. Figure 2 Also shown are the ventilation duct 7 , the vehicle interior ventilation opening 8 , the ventilation opening 14 at the bottom of the roof attachment component 22 , the solar panel 16 above the roof attachment component 21 , and the second temperature sensor 5 .

[0027] The two-way cylinder 23 can be arranged at the bottom of the support rod 13. The two output ends of the two-way cylinder 23 are respectively oriented toward the front and rear sides of the vehicle, and the two output ends of the two-way cylinder 23 are respectively connected to the roof additional component 21 and the roof additional component 22. Both sides of the roof 1 can be provided with openings, and the roof additional component 21 and the roof additional component 22 can slide at the openings of the roof 1.

[0028] As an example, the first temperature threshold is 45° and the second temperature threshold is 60°. When the temperature inside the vehicle is higher than 45° and / or the temperature outside the vehicle is higher than 60°, the control component 3 controls the two output ends of the two-way cylinder 23 to extend, thereby extending the roof additional components 21 and 22 outward through the opening of the roof 1.

[0029] After the roof additional component 21 and the roof additional component 22 are extended, the roof additional component 21 and the roof additional component 22 are hollow. After the roof additional component 21 and the roof additional component 22 are extended, the roof additional component 21 and the roof additional component 22 are hollow roof extensions.

[0030] After the roof additional component 21 and the roof additional component 22 are extended respectively, the roof additional component 21 and the roof additional component 22 can block the sunlight to prevent the sunlight from irradiating the windshield of the car.

[0031] In the disclosed embodiment, the roof may be relatively thick and may be hollow, the control component may be an electronic control unit (ECU), the control component may control the extension and retraction of the roof attachment component, the first temperature sensor may detect the internal temperature of the vehicle, the second temperature sensor may detect the external temperature of the vehicle, the first temperature sensor and the second temperature sensor respectively send the detected temperatures to the control component, and the exhaust outlet 6 may be at the bottom of the car.

[0032] When the roof additional component 21 is in the extended state, air enters the roof additional component 21 through the vents at the bottom of the roof additional component. The air entering the roof additional component 21 passes through the vents on the side walls of the roof additional component 21, the ventilation channels connected to the vents on the side walls of the roof additional component 21, and the in-vehicle vents in sequence and then enters the interior of the vehicle. The air entering the interior of the vehicle is discharged to the outside of the vehicle through the exhaust outlet 6.

[0033] When the roof additional component 22 is in the extended state, air enters the roof additional component 22 through the vents at the bottom of the roof additional component 22. The air entering the roof additional component 22 passes through the vents on the side walls of the roof additional component 22, the ventilation channels connected to the vents on the side walls of the roof additional component 22, and the in-vehicle vents in sequence and then enters the interior of the vehicle. The air entering the interior of the vehicle is discharged to the outside of the vehicle through the exhaust outlet 6.

[0034] Air can circulate inside and outside the vehicle, which can effectively reduce the temperature inside the vehicle. The control component can upload the temperature inside the vehicle to a remote terminal, such as a mobile phone, so that the user of the vehicle can conveniently check the temperature inside the vehicle through the APP in the mobile phone.

[0035] Figure 3 is a schematic structural diagram of a shielding assembly provided by an embodiment of the present invention, Figure 3The figure shows a fixing frame 91, a track 92, a traction groove 93, a gear 94, a covering cloth 95 and a motor 96 of the shielding assembly. The fixing frames 91 are respectively arranged on both sides of the front windshield inside the car, and the track 92 is arranged on the fixing frame 91. A winding drum 10 is arranged at the end of the fixing frame 91. A rotating rod 11 is rotatably arranged in the winding drum 10. The rotating rod 11 is connected to one end of the traction groove 93. The other end of the traction groove 93 is arranged in the track 92. The track 92 is slidably connected to the traction groove 93. The traction groove 93 is provided with a gear 94. The gear 94 It is meshed and connected with the traction groove 93, a connecting rod 12 is arranged between the gears 94, a covering cloth 95 is arranged on the side of the traction groove 93, a motor 96 is arranged on the side of the fixing frame 91, the output shaft of the motor 96 is connected with the gear 94, and the motor 96 is communicatively connected with the control component 3. When the temperature inside the vehicle is higher than the first temperature threshold and / or the temperature outside the vehicle is higher than the second temperature threshold, the control component 3 controls the motor 96 to rotate forward, and the forward rotation of the motor 96 drives the gear 94 to rotate, so that the covering cloth 95 on the traction groove 93 is unfolded to block the sunlight.

[0036] In the embodiment disclosed in the present invention, two fixing frames 91 can be respectively arranged on both sides of the front windshield inside the car to ensure that the fixing frames 91 do not block the driving field of vision. Tracks 92 along the direction of the fixing frames 91 are respectively opened on the two fixing frames 91. A cylindrical winding drum 10 is arranged at the end of the fixing frame 91 close to the roof 1. The side of the winding drum 10 close to the fixing frame 91 is open. A rotating rod 11 is rotatably arranged on the side wall inside the winding drum 10. The ends of the same side ends of the two traction grooves 93 are fixedly arranged on the surface of the rotating rod 11. The ends of the other ends of the two traction grooves 93 are respectively arranged in two tracks 92. The traction grooves 93 can slide in the tracks 92. Gears 94 are respectively arranged on the surfaces of the two traction grooves 93. The gears 94 and the traction grooves 93 are meshed and connected. A connecting rod 12 is arranged between the two gears 94, so that the two gears 94 can rotate synchronously. A covering cloth 95 is provided on the side close to the traction groove 93. When the gear 94 rotates, the traction groove 93 can be driven to move, thereby driving the covering cloth 95 to move. A motor 96 is provided on the side of the fixed frame 91, and the output shaft of the motor 96 is fixedly connected to the middle part of the gear 94. In the initial state, most of the traction groove 93 and the covering cloth 95 are rolled up on the rotating rod 11 in the winding drum 10. When the temperature inside the vehicle is higher than the first temperature threshold and / or the temperature outside the vehicle is higher than the second temperature threshold, the control component 3 controls the motor 96 to rotate forward, thereby controlling the gear 94 to rotate and pull the traction groove 93 and the covering cloth 95 out of the winding drum 10. When one end of the traction groove 93 located in the track 92 reaches the end of the track 92, the control component 3 controls the motor 96 to stop rotating. At this time, the covering cloth 95 is opened below the front windshield to block the sunlight and prevent the sunlight from entering the interior of the car after refraction and reflection.

[0037] In an optional embodiment, the exhaust fan is communicatively connected to the control component, and when the temperature inside the vehicle is higher than a first temperature threshold and / or the temperature outside the vehicle is higher than a second temperature threshold, the control component controls the exhaust fan to turn on, which can accelerate the air circulation inside the vehicle, thereby effectively reducing the temperature inside the vehicle. This prevents the sunlight from directly shining through the front windshield into the interior of the vehicle and causing a temperature rise, and can prevent the temperature inside the vehicle from being too high.

[0038] In an optional embodiment, a first temperature sensor is disposed inside the vehicle, and a second temperature sensor is disposed above the roof 1. When the temperature inside the vehicle is higher than a first temperature threshold and / or the temperature outside the vehicle is higher than a second temperature threshold, the control component controls the motor 96 to rotate forward, controls the two telescopic ends of the bidirectional cylinder 23 to extend, and controls the exhaust fan to turn on.

[0039] In the disclosed embodiment, a solar panel is provided above the roof additional component, and there is also a battery in the car. The entire device can operate normally when the solar panel is not working. When the roof additional component is in an extended state, the solar panel 16 is exposed to the sun, and after being exposed to the sun, the solar energy is converted into electrical energy, and then stored, which can power the fan at the exhaust outlet and the control component.

[0040] In an optional embodiment, when the roof attachment component is in the extended state and the temperature inside the vehicle is lower than the third temperature threshold, the control component controls the motor 96 to rotate in the opposite direction, controls the two telescopic ends of the bidirectional cylinder 23 to contract, and controls the exhaust fan to close.

[0041] In the disclosed embodiment, the third temperature threshold may be less than the first temperature threshold and less than the second temperature threshold. As an example, the third temperature threshold is 30°. When the temperature inside the vehicle is lower than the third temperature threshold, since there is no active air conditioning cooling function, it may be that the weather starts to rain and the temperature of the entire environment drops. The control component controls the motor 96 to rotate in the opposite direction, and retracts the traction groove 93 and the cover cloth 95 into the reel 10. The control component controls the two telescopic ends of the two-way cylinder 23 to contract and retract the top additional component 21 and the roof additional component 22, so that the roof additional component is changed from an extended state to an unextended state. To avoid losses caused by rainwater being brought into the interior of the car during air circulation, the control component controls the exhaust fan to close to avoid excessively low temperatures in the car due to accelerated air circulation.

[0042] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
