When the car door is closed, the gas pushes away the blades 320 to be discharged.

[0046] The pressure relief valve frame 310 and the blades 320 can be realized by the existing technology, and excessive description is not given here.

[0047] In a specific embodiment, the cover body 100 is connected with the body sheet metal of the car through soft rubber sealing, which further improves the sealing performance and prevents dust, polluted air and water outside the car from entering the car through the connection between the cover body 100 and the body sheet metal of the car.

[0048] In a specific embodiment, it further comprises a rear bevel door 240, the opposite sides of the cover body 100 are both provided with pressure relief ports, and the front bevel door 230 and the rear bevel door 240 are oppositely arranged on the two sides of the cover body 100 and correspond to the pressure relief ports respectively.

[0049] Further, the transmission assembly further comprises a third connecting rod 211, a fourth connecting rod 212 and an eccentric wheel 221. The eccentric wheel 221 is drivingly connected with the motor, and drives the eccentric wheel 221 to rotate in the circumferential direction. The two ends of the third connecting rod 211 are respectively connected with the eccentric wheel 221 and the rear bevel door 240. The driving motor 110 drives the third connecting rod 211 to drive the rear bevel door 240 to a position away from the pressure relief port. The transmission assembly further comprises the fourth connecting rod 212. One end of the fourth connecting rod 212 is rotatably connected with one end of the third connecting rod 211, and the other end is rotatably connected with the position of the pressure relief port of the cover body 100. The rear bevel door 240 is arranged on the fourth connecting rod 212, and the plate surface is attached to and fixedly connected with the fourth connecting rod 212.

[0050] In this specific embodiment, the eccentric wheel 221 is drivingly connected with the driving motor 110, and the driving motor 110 drives the eccentric wheel 221 to rotate in the circumferential direction. The two ends of the third connecting rod 211 are respectively connected with the eccentric wheel 221 and the rear bevel door 240. The driving motor 110 drives the third connecting rod 211 to drive the rear bevel door 240 to a position away from the pressure relief port. One end of the fourth connecting rod 212 is rotatably connected with one end of the third connecting rod 211, and the other end is rotatably connected with the position of the pressure relief port of the cover body 100. The rear bevel door 240 is arranged on the fourth connecting rod 212, and the plate surface is attached to and fixedly connected with the fourth connecting rod 212. Through this transmission structure, the rear bevel door 240 can be synchronously or independently opened and closed with the front bevel door 230, meeting the pressure relief and waterproof requirements in different working conditions.

[0051] The opening and closing mode of the rear bevel door 240 is the same as that of the front bevel door 230, and is arranged opposite to the front bevel door 230. In the normal state, the two pressure relief ports are opposite, facilitating the pressure relief of the pressure relief valve assembly.

[0052] In a specific embodiment, the transmission assembly further comprises a synchronous transmission shaft 120. The reducer and the synchronous transmission shaft 120 are arranged in the cover body 100. One end of the synchronous transmission shaft 120 is connected with the center position of the plate surface of the eccentric wheel 221, and the other end is connected with the reducer. The driving motor 110 is drivingly connected with the synchronous transmission shaft 120 through the reducer, and drives the eccentric wheel 221 to rotate around the circumferential direction of the synchronous transmission shaft 120. The synchronous transmission shaft 120 is connected with the output shaft of the driving motor 110 through the reducer, and passes through the eccentric wheel 221 to drive the eccentric wheel 221 to rotate in the circumferential direction. When the driving motor 110 is started, the synchronous transmission shaft 120 drives the eccentric wheel 221 to rotate in the circumferential direction, ensuring the synchronization of the actions of the front bevel door 230 and the rear bevel door 240, making the pressure relief valve more stable and reliable in the working process, and avoiding problems such as poor sealing or poor pressure relief caused by inconsistent actions of the front and rear bevel doors 240.

[0053] In a specific embodiment, the cover 100 is in the shape of an isosceles trapezoid in the direction of the opening of the vertical pressure relief port, and one side of the cover 100 is provided with a pressure relief valve mounting port, and the cross section of the cover 100 gradually decreases in the direction away from the pressure relief valve mounting port. The structure of the cover 100 is beneficial to increase the internal volume of the pressure relief valve in a limited space and improve the pressure relief efficiency. The isosceles trapezoidal structure makes the cover 100 more conformable when installed on the outer side wall of the automobile, thereby reducing wind resistance and noise. In addition, one side of the cover 100 is provided with a pressure relief valve mounting port, and the cross section of the cover 100 gradually decreases in the direction away from the pressure relief valve mounting port. This design helps to guide the airflow to smoothly pass through the pressure relief port, and at the same time, when the corner door is closed, the water pressure can be better utilized to increase the sealing effect and improve the waterproof performance.

[0054] In a specific embodiment, when the pressure relief port is closed by the inclined corner door, the center of the eccentric wheel 221 is located between the inclined corner door and the rotation position of the first connecting rod 223 and the eccentric wheel 221. One side wall of the cover is provided with a pressure relief side wall, the pressure relief side wall is provided with a pressure relief port, and the inclined corner door is rotatably arranged on the pressure relief side wall. The eccentric wheel 221 is in the shape of a square plate. When the front inclined corner door 230 and the rear inclined corner door 240 are sealingly fixed to the cover 100, the eccentric wheel 221 is obliquely arranged, i.e. the connection rotation position of the eccentric wheel 221 and the first connecting rod 223 and the rear inclined corner door 240 are located on both sides of the connection position of the eccentric wheel 221 and the synchronous transmission shaft 120, and the connection rotation position of the eccentric wheel 221 and the third connecting rod 211 and the front inclined corner door 230 are located on both sides of the connection position of the eccentric wheel 221 and the synchronous transmission shaft 120, thereby completing the self-locking of the first connecting rod 223 and the third connecting rod 211 relative to the eccentric wheel 221.

[0055] The first connecting rod 223 and the third connecting rod 211 are both in the shape of a rod. The cross section of the first connecting rod 223 is a straight line, and the third connecting rod 211 has a certain inclination angle, which is beneficial to the rotation connection of the first connecting rod 223 and the third connecting rod 211 with the length direction of the two sides of the eccentric wheel 221.

[0056] In a specific embodiment, the cross section of the cover 100 is in the shape of an isosceles trapezoid, i.e. two waists are provided with pressure relief ports, and the front inclined corner door and the rear inclined corner door are respectively arranged outside. When the two inclined corner doors are completely opened, the cross section of the cover 100 and the two inclined corner doors is in the shape of a rectangle, i.e. the inclined corner door form can realize a large enough ventilation space with a small movement amount, and can be opened and closed in a given rectangular space without occupying additional space.

[0057] The inclined door is a plate body structure, and a protection plate body extends from the side edge position towards the pressure relief port. In addition, the cross section of the protection plate body is arc-shaped, and the cross section length and the cross section width of the protection plate body are greater than the cross section length and the cross section width of the inclined door, so that the annular structure of the protection plate body can completely cover the pressure relief port, and the connection sealing performance of the inclined door and the pressure relief port is improved.

[0058] The inclined door is a plate body structure, and a sealing ring is arranged at the side edge position towards the pressure relief port. The sealing ring is matched with the pressure relief port. When the inclined door is closed, the sealing ring is in sealing connection with the pressure relief port.
