Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, and more specifically to a vehicle pressure relief valve with an active sealing function. Background Art

[0002] The body pressure relief valve is a key component related to the balance of air pressure inside and outside the vehicle. It consists of a pressure relief valve body and a pressure relief valve disc. The valve disc can be installed in the pressure relief channel to move under air pressure to close or open the pressure relief channel. When the air pressure inside the vehicle increases, the air pressure drives the valve disc to open the pressure relief channel to release pressure. When the air pressure inside the car is balanced, the valve disc closes the pressure relief channel.

[0003] The pressure relief valve is an important component that directly affects the closing force and closing sound quality of the car door.

[0004] Although the pressure relief valve is a one-way airflow channel, water often flows into the car through the pressure relief valve when passing through water, which is bound to cause great property losses to consumers. Utility Model Content

[0005] In view of the deficiencies and defects of the existing technology, a vehicle pressure relief valve with an active sealing function is provided, which can retain the functionality of the normal use of the pressure relief channel and improve the isolation performance of the vehicle interior space.

[0006] A vehicle pressure relief valve with active sealing function, comprising:

[0007] a housing, wherein a pressure relief passage is provided on the housing, wherein an inner end of the pressure relief passage is connected to the interior space of the vehicle, and an outer end of the pressure relief passage is connected to the external environment;

[0008] a valve plate, the valve plate being movably mounted in the pressure relief channel under air pressure to movably close or open the pressure relief channel;

[0009] The sealing part is arranged in cooperation with the pressure relief channel, and the sealing part is driven to move by the driving mechanism. The driving mechanism drives the sealing part to move to the closed pressure relief channel so that the interior space of the vehicle is disconnected from the external environment. The driving mechanism drives the sealing part to move to the open pressure relief channel so that the interior space of the vehicle is connected to the external environment.

[0010] With the above structure, the vehicle pressure relief valve with active sealing function of the present invention has the following advantages over the prior art: when the vehicle interior needs to be isolated from the external environment (for example, to prevent water from the external environment from entering the vehicle interior), the driving mechanism drives the sealing portion to seal the pressure relief channel. At this time, the vehicle interior is disconnected from the external environment, and the medium cannot enter or exit the vehicle interior through the pressure relief channel, thereby improving the isolation performance of the vehicle interior.

[0011] When it is necessary to connect the interior space of the vehicle with the external environment, the driving mechanism drives the sealing part to open the pressure relief channel. At this time, the interior space of the vehicle and the external environment are in a connected state, and the medium can enter and exit the interior space of the vehicle through the pressure relief channel, retaining the functionality of normal use.

[0012] As an improvement of the present invention, the sealing portion is arranged at the outer end of the pressure relief channel. The sealing portion is made of soft rubber material and can be moved to be close to the outer end outlet of the pressure relief channel.

[0013] As an improvement of the present invention, the shell is provided with a smooth mating surface around the outer end outlet of the pressure relief channel, the sealing portion extends to the peripheral side of the mating surface, and a rib is provided at a position opposite to the mating surface of the sealing portion, and the rib is provided around the outer end outlet of the pressure relief channel.

[0014] As an improvement of the present invention, it also includes a pressure sensor, which is arranged at the outer end of the pressure relief channel. The pressure sensor is electrically connected to the driving mechanism. When the pressure sensor monitors the water pressure signal, the driving mechanism drives the sealing part to move to the closed pressure relief channel.

[0015] As an improvement of the present invention, the driving mechanism includes an actuator, a crank, and a linkage rod. The actuator is installed at the inner end of the shell, the crank is connected to the output end of the actuator, one end of the linkage rod is hinged to the crank, and the other end is hinged to the inner end of the sealing part.

[0016] As an improvement of the present invention, the outer end cover of the pressure relief channel is provided with a protective cover, and the side wall of the protective cover is provided with a plurality of through holes at intervals along the moving direction of the sealing portion.

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] See also Figure 1-5 As shown, a vehicle pressure relief valve with active sealing function includes:

[0025] A housing 1 is provided with a pressure relief passage 1.1, wherein the inner end of the pressure relief passage 1.1 is connected to the interior of the vehicle and the outer end is connected to the external environment;

[0026] a valve plate 2, the valve plate 2 being movably mounted in the pressure relief channel 1.1 under air pressure to movably close or open the pressure relief channel 1.1;

[0027] The sealing portion 3 is arranged to cooperate with the pressure relief channel 1.1, and the sealing portion 3 is driven to move by the driving mechanism 4. The driving mechanism 4 drives the sealing portion 3 to move to the closed pressure relief channel 1.1, so that the interior space of the vehicle is disconnected from the external environment. The driving mechanism 4 drives the sealing portion 3 to move to the open pressure relief channel 1.1, so that the interior space of the vehicle is connected to the external environment.

[0028] When the interior of the vehicle needs to be isolated from the outside environment, the driving mechanism 4 drives the sealing portion 3 to seal the pressure relief channel 1.1. At this time, the interior of the vehicle is disconnected from the outside environment, and the medium cannot enter or exit the interior of the vehicle through the pressure relief channel 1.1, thereby improving the isolation performance of the interior of the vehicle.

[0029] When the interior of the vehicle needs to be connected to the outside environment, the driving mechanism 4 drives the sealing part 3 to open the pressure relief channel 1.1. At this time, the interior of the vehicle is in a connected state with the outside environment, and the medium can enter and exit the interior of the vehicle through the pressure relief channel 1.1, retaining the functionality of normal use.

[0030] A grid is set on the inside of the pressure relief channel 1.1 to form multiple windows, and the valve plate 2 is set to cover the outside of the window. One end of the valve plate 2 is hinged to the grid, and the other end is a free end. The inner side is placed on the limit block of the window and forms an outward-inclined angle from top to bottom.

[0031] When assembling the device, the device can be kept in a vertical setting. When the air pressure in the vehicle interior increases, the high air pressure will drive the valve plate 2 to rotate outward until the window is open, thereby opening the pressure relief channel 1.1 and releasing the pressure in the vehicle interior.

[0032] When the pressure relief in the vehicle interior is complete, the valve plate 2 can be reset to the position of shielding the window under the influence of its own gravity, so that the pressure relief channel 1.1 is in a closed state.

[0033] When the external ambient pressure increases, the valve plate 2 can be reset to the position of shielding the window.

[0034] See also Figure 2-3 As shown, the sealing portion 3 is disposed at the outer end of the pressure relief channel 1.1. The sealing portion 3 is made of a soft rubber material and can be moved to closely contact the outer outlet of the pressure relief channel 1.1. The soft material sealing portion 3 is disposed at the outer end of the pressure relief channel 1.1. When the driving mechanism 4 drives it inward, it can closely contact the outer outlet of the pressure relief channel 1.1 to seal the pressure relief channel 1.1. After the above improvement, the pressure relief channel 1.1 has a simple structure, reliable operation, and can be more stably and tightly sealed, further improving the sealing performance.

[0035] The housing 1 is provided with a smooth mating surface 1.11 around the outer end outlet of the pressure relief channel 1.1. The sealing portion 3 extends to the circumference of the mating surface 1.11, and a rib 3.1 is provided at a position opposite the mating surface 1.11 of the sealing portion 3. The rib 3.1 is provided around the outer end outlet of the pressure relief channel 1.1.

[0036] An annular rib 3.1 is formed on the inner side of the sealing portion 3 to reduce the contact surface. The rib 3.1 can stably and effectively press against the mating surface 1.11, further improving the sealing performance and effectively preventing the medium from passing through the gap and entering the pressure relief channel 1.1.

[0037] See also Figure 1-2 As shown, it also includes a pressure sensor 5, which is arranged at the outer end of the pressure relief channel 1.1. The pressure sensor 5 is electrically connected to the driving mechanism 4. When the pressure sensor 5 detects a water pressure signal, the driving mechanism 4 drives the sealing part 3 to move to the closed pressure relief channel 1.1.

[0038] A pressure sensor 5 is used to detect the pressure of the external environment. When the external environmental pressure increases, a control signal is automatically sent to the driving mechanism 4, which starts and drives the sealing part 3 to move to the closed pressure relief channel 1.1;

[0039] See also Figure 4-5 As shown, the driving mechanism 4 includes an actuator 4.1, a crank 4.2, and a linkage rod. The actuator 4.1 is installed at the inner end of the housing 1, the crank 4.2 is connected to the output end of the actuator 4.1, and one end of the linkage rod is hinged to the crank 4.2 and the other end is hinged to the inner end of the sealing part 3.

[0040] The driving mechanism 4 mentioned above has the characteristics of simple structure and large torque, which can increase the locking force between the rib 3.1 and the matching surface 1.11, and further improve the sealing performance.

[0041] See also Figure 1-3 As shown, the outer end cover of the pressure relief channel 1.1 is provided with a protective cover 6, and the side wall of the protective cover 6 is provided with a plurality of through holes 6.1 at intervals along the moving direction of the sealing part 3.

[0042] The protective cover 6 can play a protective role and effectively prevent external debris from entering;

[0043] Several through holes 6.1 are arranged at intervals on the protective cover 6 along the moving direction of the sealing part 3. Preferably, three rows are arranged at intervals. When the sealing part 3 moves, the through holes 6.1 at the corresponding positions can be opened or closed (for example, one row, two rows, or three rows can be opened), and the connection state can be adjusted in multiple gears.

[0044] The above-mentioned vehicle pressure relief valve with active sealing function is assembled on a fixed plate 7, and then the fixed plate 7 is connected to the vehicle. The entire device is arranged in an upright manner. The pressure sensor 5 is arranged on the fixed plate 7 below the pressure relief channel 1.1, and the pressure sensors 5 can be arranged in two rows from top to bottom.

[0045] When the vehicle is wading, if the pressure sensor 5 in the lower row detects the water pressure signal, it will output an alarm signal;

[0046] If the upper pressure sensor 5 detects a water pressure signal, it will send a control signal to the drive mechanism 4 and drive the sealing part 3 to move inward through the actuator 4.1 to seal the outer end outlet of the pressure relief channel 1.1. After the above improvement, the vehicle's airtightness can be improved, which can effectively prevent foreign matter from entering and improve the water wading performance.

[0047] The above are only preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
