Therefore, these and other directional terms should not be construed as limiting terms. Furthermore, the terms "first," "second," "third," and the like are used for descriptive and descriptive purposes only and not for purposes of indication or implication as to the relative importance of the respective components.

Referring to fig. 1, a schematic structural diagram of a pressure relief valve according to an embodiment of the present invention is shown. For convenience of description, a direction from the roof to the underbody along the vertical axis of the vehicle is defined as an up-down direction. The pressure relief valve 100 is used for relieving pressure of air in an automobile compartment and comprises a valve body 1, a valve plate 2 and a driving motor 3. The valve body 1 is arranged in a through hole of an automobile body, and a sealing element is arranged between the through hole and the valve body 1 and used for sealing a gap between the valve body 1 and the through hole. A valve duct 11 is formed on the valve body 1 for connecting the environment outside the vehicle to the environment inside the vehicle cabin for ventilation and pressure relief. The valve passage 11 is generally rectangular-like in cross-section in the direction of gas flow therein, although other shapes are possible. The valve plate 2 is arranged in the valve body 1, in particular at the opening of the valve duct 11 facing the environment outside the vehicle. The valve plate 2 is configured to match the cross-sectional shape of the valve channel 11, so that the valve plate 2 can close the valve channel 11, so that the valve plate 2 is also configured, for example, as a rectangle, although the valve plate 2 can also be configured as other shapes. The valve plate 2 is connected with the valve body 1 through the rotating shaft 4, so that the valve plate 2 can rotate relative to the valve body 1, when the valve plate 2 rotates to be parallel to the cross section of the valve channel 11, the valve channel 11 is completely sealed by the valve plate 2, no gas can overflow from the pressure release valve 100, and when the valve plate 2 rotates to other positions, the valve channel 11 is opened, and the gas overflows from the pressure release valve 100. The valve plate 2 rotates at a maximum angle of 90 ° with respect to the valve body 1. It is defined here that the angle of rotation of the valve plate 2 is 0 ° when the valve plate 2 is parallel to said cross section of the valve channel 11, and 90 ° when the valve plate 2 is perpendicular to said cross section of the valve channel 11, i.e. when the valve channel 11 is fully open. The valve plate 2 is thus rotated through an angle of from 0 to 90 deg., and the degree of opening of the valve passage 11 is gradually increased until it is fully opened.

The driving motor 3 is installed on the valve body 1, and an output end of the driving motor 3 is connected to the rotating shaft 4 so as to rotatably drive the rotating shaft 4. Referring to fig. 2, a schematic connection diagram of the valve sheet 2 and the motor 3 of the pressure relief valve 100 according to an embodiment of the present invention is shown. In this embodiment, the rotation shaft 4 is connected to the valve plate 2 on an axis of symmetry of the valve plate 2 perpendicular to its short sides such that the valve plate 2 can be rotated about this axis of symmetry, and the rotation shaft 4 extends over the entire length of the valve plate 2. Such a connection enables the width of a single valve plate 2 to be constructed small and the rotation of the valve plate 2 to be stable. It should be understood that the rotation shaft 4 may also be connected to the valve plate 2 at the upper edge of the valve plate 2, i.e. the edge of the valve plate 2 closer to the vehicle roof in the state of closing the valve channel 11, so that the valve plate 2 can rotate around its upper edge. Such a connection prevents water or other material flowing down from above the pressure relief valve 100 from entering the pressure relief valve 100, since it is just stopped by the valve plate 2 during the flow down.

In this embodiment, the relief valve 100 has two valve plates 2 and two drive motors 3 (one of which is not shown in the figure), and the two valve plates 2 are connected to the two drive motors 4 via rotary shafts 4 arranged parallel to each other, respectively. In an embodiment not shown, there can be a plurality of valve plates in any number, the valve plates can be respectively connected to a plurality of driving motors corresponding to the number of the valve plates through rotating shafts arranged in parallel to each other, each driving motor drives its corresponding valve plate, the valve plates can also be coaxially connected to one driving motor through one rotating shaft, and the one driving motor drives all the valve plates at the same time, and the gas flow area and the flow rate of the relief valve can be increased by using the valve plates.

In this embodiment, because valve block 2 passes through driving motor 3 drive, so valve block 2 can be constructed to be thicker than the valve block of the relief valve among the prior art, consequently valve block 2 can be made through polyethylene (PP) material, makes valve block 2 sturdy and thick and heavy more like this, is difficult for receiving outside influence and opens easily and has strengthened the syllable-dividing effect. In addition, at the contact portion of the valve sheet 2 and the valve body 1, that is, the peripheral portion of the valve channel 11 sealed by the valve sheet 2, the valve sheet 2 is injection molded by a thermoplastic elastomer (TPE), so as to ensure that the valve sheet 2 can completely seal the valve channel 11. It will be understood that the valve plate 2 can also be made of other acoustically and chemically stable materials.

In this embodiment, the driving motor 3 is a servo motor, the servo motor 3 is electrically connected to an Electronic Control Unit (ECU) of the vehicle, and the servo motor 3 can send a feedback signal to the electronic control unit to feed back the state of the servo motor 3 and the current valve opening, so that when the motor 3 fails, a user can be reminded of repairing the valve and the valve opening can be controlled more accurately through the electronic control unit.

It should be understood that the pressure relief valve of the present invention may be installed on a variety of vehicles, including cars, vans, buses, and the like. Therefore, the subject matter of the present invention is also intended to protect various vehicles equipped with the pressure relief valve of the present invention.
