Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, specifically to an electromagnetic pressure relief valve and a vehicle. Background Technology

[0002] Body pressure relief valves are typically located in the vehicle doors or rear panel to vent air from the passenger compartment. These valves are usually passive, meaning their valve plates are lightweight to balance the pressure difference between the inside and outside of the vehicle using their own weight. This means the valve may not close automatically when vehicle speed changes rapidly, causing severe ear discomfort for passengers. Furthermore, during high-speed driving, in rainy conditions, or in environments with poor air quality or high levels of pollution such as dust or insects, the exhaust passage of the pressure relief valve remains open, leading to increased road noise, mold or corrosion of the interior, and the entry of contaminants into the vehicle. Moreover, the presence of a passive pressure relief valve means that over 70% of the recirculated airflow is exhausted through it, preventing the air conditioning system from effectively recovering and utilizing the waste heat from the exhaust air from the passenger compartment. Utility Model Content

[0003] This utility model aims to at least partially solve one of the technical problems in the related art.

[0004] Therefore, embodiments of this utility model propose an electromagnetic pressure relief valve, which can actively close the exhaust passage, effectively regulate the pressure balance inside the vehicle, ensure a clean environment inside the vehicle under harsh driving conditions, and recover residual heat from the passenger compartment.

[0007] According to the embodiment of this utility model, the electromagnetic pressure relief valve is configured such that an electromagnetic coil is connected to a valve seat and a metal plate is connected to a valve plate. Under specific operating conditions, energizing the electromagnetic coil causes it to magnetically connect with the metal plate, maintaining the valve plate in the first position of closing the exhaust passage, thus actively closing the exhaust passage. These specific operating conditions can include rapid changes in vehicle speed, thereby preventing drastic pressure changes inside the vehicle and effectively regulating the pressure balance; high-speed driving conditions, thereby improving the sound insulation of the vehicle body at the electromagnetic pressure relief valve, resulting in low driving noise; rain conditions, thereby preventing mold growth on the interior and corrosion of components caused by prolonged rainy weather; poor air quality or severe pollution conditions with high levels of dust and insects, thereby preventing pollutants from entering the vehicle and effectively ensuring a clean interior environment; and winter conditions, thereby preventing residual heat from the passenger compartment from being discharged to the outside of the vehicle through the electromagnetic pressure relief valve, resulting in high heat recovery and utilization rates.

The electromagnetic pressure relief valve further includes a first latch and a second latch, both of which are connected to the fixed base and are arranged at intervals along the extension direction of the limiting hole. The electromagnetic coil is located between the first latch and the second latch.

[0011] In some embodiments, the valve plate is made of a flexible material.

[0027] The embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0028] The following is combined with Figures 1-5 This invention describes an electromagnetic pressure relief valve according to an embodiment of the present invention.

[0029] The electromagnetic pressure relief valve of this embodiment includes a valve seat 1, a valve plate 2, an electromagnetic coil 3, and a metal plate 4. The valve seat 1 has an exhaust passage 11. The valve plate 2 is pivotally connected to the valve seat 1 and has a first position with the exhaust passage 11 closed and a second position with the exhaust passage 11 open. The electromagnetic coil 3 is connected to the valve seat 1, and the metal plate 4 is connected to the valve plate 2. When energized, the electromagnetic coil 3 is magnetically attracted to the metal plate 4 to maintain the valve plate 2 in the first position.

[0030] According to the embodiment of this utility model, the electromagnetic pressure relief valve is configured such that an electromagnetic coil 3 is connected to a valve seat 1, and a metal plate 4 is connected to a valve plate 2. Under specific operating conditions, energizing the electromagnetic coil 3 causes it to magnetically connect with the metal plate 4, thus maintaining the valve plate 2 in the first position of closing the exhaust passage 11, i.e., actively closing the exhaust passage 11. These specific operating conditions can include rapid changes in vehicle speed, thereby preventing drastic pressure changes inside the vehicle and effectively regulating the pressure balance; high-speed driving conditions, thereby improving the sound insulation of the vehicle body at the electromagnetic pressure relief valve, resulting in low driving noise; rain conditions, thereby preventing mold growth in the interior and corrosion of components caused by prolonged rainy weather; poor air quality or severe pollution conditions such as dust and insects, thereby preventing pollutants from entering the vehicle and effectively ensuring a clean interior environment; and winter conditions, thereby preventing residual heat from the passenger compartment from being discharged to the outside of the vehicle through the electromagnetic pressure relief valve, resulting in high heat recovery and utilization rates.

[0031] It should be noted that the metal plate 4 is made of iron or steel. When the electromagnetic pressure relief valve is not energized, the valve plate 2 hangs down naturally and is in the first position where the exhaust passage 11 is closed. The sum of the component of the weight of the valve plate 2 and the added weight of the metal plate 4 in the direction perpendicular to the valve plate 2 is less than the component of the wind force in the direction perpendicular to the valve plate 2 when the blower airflow is at its minimum. That is, even the minimum airflow can blow open the valve plate 2 in its natural state. When the electromagnetic coil 3 is energized, the wind force generated on the valve plate 2 at the maximum blower airflow is less than the magnetic force of the electromagnetic coil 3 attracting the metal plate 4. In addition, the vehicle judges the weather conditions and air quality outside the vehicle based on rain sensors, air quality sensors, etc., and actively closes the electromagnetic pressure relief valve in rainy weather and heavily polluted air environments to prevent rainwater and pollutants from entering the passenger compartment.

[0032] In some embodiments, when the valve plate 2 is in the first position, the electromagnetic coil 3 abuts against the metal plate 4.

[0033] At this time, when the electromagnetic coil 3 is energized, the electromagnetic coil 3 and the metal plate 4 obtain the maximum attraction force, thereby making the valve plate 2 more reliable in sealing the exhaust passage 11 and able to adapt to more complex and harsh working conditions. In other words, a lower power and smaller size electromagnetic coil 3 can be used to achieve reliable sealing of the exhaust passage 11, and the cost of the electromagnetic pressure relief valve is lower.

[0034] In some embodiments, such as Figure 1 and Figure 3 As shown, the electromagnetic pressure relief valve also includes a fixed seat 12, which is located in the exhaust channel 11. The electromagnetic coil 3 is connected to the fixed seat 12. When the valve plate 2 is in the first position, the fixed seat 12 abuts against the valve plate 2 to support the valve plate 2.

[0035] The mounting bracket 12 facilitates the fixed installation of the electromagnetic coil 3 and provides reliable support for the valve plate 2 located in the first position. The valve plate 2 is less likely to deform away from the second position when the pressure difference between the inside and outside of the vehicle body is large, thus affecting the sealing reliability of the exhaust passage 11.

[0036] For example, the fixed seat 12 is integrally formed with the valve seat 1, and the exhaust channel 11 is also provided with a grid-like or mesh-like limiting plate. The limiting plate abuts against the valve plate 2 located in the first position to support the valve plate 2. The limiting plate is integrally formed with the valve seat 1, and the fixed seat 12 is disposed on the limiting plate.

[0037] In some embodiments, the fixed base 12 has a limiting hole 15, and the electromagnetic coil 3 is disposed in the limiting hole 15, with the axial direction of the electromagnetic coil 3 aligned with the extending direction of the limiting hole 15. The electromagnetic pressure relief valve also includes a first latch 13 and a second latch 14, both of which are connected to the fixed base 12 and are arranged at intervals along the extending direction of the limiting hole 15, with the electromagnetic coil 3 disposed between the first latch 13 and the second latch 14.

[0038] The limiting hole 15 limits the electromagnetic coil 3 radially, while the first latch 13 and the second latch 14 limit the electromagnetic coil 3 axially. The limiting reliability of the electromagnetic coil 3 on the fixed base 12 is high, effectively preventing the electromagnetic coil 3 from vibrating and affecting the sealing reliability of the valve plate 2 to the exhaust channel 11. Moreover, this arrangement also facilitates the exposure of the electromagnetic coil 3, thus allowing a portion of the metal plate 4 to extend into the limiting hole 15 and abut against the electromagnetic coil 3 when the valve plate 2 is in the first position.

[0039] For example, such as Figure 2 and Figure 3As shown, the extension direction of the limiting hole 15 is consistent with the extension direction of the exhaust channel 11. The limiting hole 15 passes through the fixing seat 12. The first buckle 13 and the second buckle 14 are respectively disposed at both ends of the limiting hole 15. The first buckle 13 is disposed inside the limiting hole 15 and is disposed adjacent to the valve plate 2 relative to the second buckle 14. The first buckle 13 consists of two protrusions disposed on the inner surface of the limiting hole 15. The two protrusions are arranged at intervals along the circumference of the limiting hole 15. When the valve plate 2 is in the first position, the thickness of the part of the metal plate 4 located inside the limiting hole 15 is equal to the thickness of the protrusions.

[0040] In some embodiments, the valve plate 2 is made of a flexible material. This makes the valve plate 2 lighter, easier to switch between the first and second positions, and provides a larger contact area with the valve seat 1 when the valve plate 2 is in the first position, resulting in a better sealing effect. Furthermore, it avoids rigid collisions between the valve plate 2 and the valve seat 1 when switching between the first and second positions, thus preventing excessive noise.

[0041] For example, valve plate 2 is made of nitrile rubber.

[0042] In some embodiments, the electromagnetic pressure relief valve further includes a support rib 5, which is connected to the valve plate 2 and is used to support the valve plate 2.

[0043] With the valve plate 2 made of a flexible material, the support rib 5 is used to keep the valve plate 2 in the unfolded state, thereby ensuring that the valve plate 2 in the first position has high reliability in sealing the exhaust channel 11.

[0044] For example, the support rib 5 is made of iron wire with a circular cross-section.

[0045] In some embodiments, the support rib 5 is disposed on the edge of the valve plate 2, and the extending direction of the support rib 5 is consistent with the extending direction of the edge of the valve plate 2.

[0046] This ensures that the valve plate 2 is reliably maintained in the unfolded state, while also reducing the number of support ribs 5 arranged on the valve body, thus ensuring that the valve plate 2 maintains its original elastic function.

[0047] Optionally, the support rib 5 includes multiple ribs 51, which are spaced apart along the extension direction of the edge of the valve plate 2. This ensures that the valve plate 2 is reliably maintained in the deployed state, while each rib 51 can be independently fixed in a set position on the valve plate 2. The assembly of the ribs 51 on the valve plate 2 is easier and more efficient.

[0048] For example, such as Figure 5 As shown, taking the valve plate 2 as a rectangular plate as an example, the ribs 51 are arranged on the left, right and bottom edges of the valve plate 2, and the top of the valve plate 2 is pivotally connected to the valve seat 1.

[0049] In some embodiments, such as Figure 5As shown, the support rib 5 is embedded within the valve plate 2. This design ensures high connection strength between the support rib 5 and the valve plate 2, preventing the support rib 5 from easily falling off and providing good support for the valve plate 2. On the other hand, it avoids direct contact between the support rib 5 and the valve seat 1, which could cause excessive noise.

[0050] For example, the support rib 5 can be iron wire, which is pre-embedded in the valve plate 2.

[0051] In some embodiments, the top of the valve plate 2 is pivotally connected to the valve seat 1, and the metal plate 4 is disposed at the bottom of the valve plate 2. This allows the valve plate 2 to maintain the first position of closing the exhaust passage 11 under its own weight. For example, when the vehicle is not started, the exhaust passage 11 can be kept closed without energizing the electromagnetic coil 3, effectively keeping the interior of the vehicle clean.

[0052] Optionally, there are at least two metal plates 4 arranged at intervals along the pivot axis of the valve plate 2. That is, at least two electromagnetic coils 3 achieve the attraction and fixation of the valve plate 2, the valve plate 2 maintains higher reliability in the first position, and the valve plate 2 in the first position is less likely to undergo local deformation, which would lead to incomplete sealing and poor sealing of the exhaust passage 11.

[0053] For example, each valve plate 2 corresponds to three metal plates 4, which are arranged along the length of the valve plate 2 at the left edge, right edge and center of the bottom of the valve plate 2, respectively.

[0054] In some embodiments, the metal sheet 4 is snapped into the valve plate 2, and the main body of the metal sheet 4 is located on the side of the valve plate 2 facing the electromagnetic coil 3.

[0055] This makes the disassembly of the metal plate 4 on the valve plate 2 highly efficient, and facilitates the contact between the metal plate 4 and the electromagnetic coil 3 to ensure a lower attraction force between them.

[0056] For example, the metal sheet 4 includes at least two claws that penetrate the valve plate 2 and bend against the side of the valve plate 2 away from the electromagnetic coil 3.

[0057] In some embodiments, there are at least two exhaust passages 11 arranged side by side, and the valve plate 2 corresponds one-to-one with the exhaust passage 11.

[0058] That is, each electromagnetic pressure relief valve is equipped with at least two valve plates 2, and each valve plate 2 is relatively independent. Thus, even if a valve plate 2 cannot move due to various accidents, such as when a valve plate 2 is stuck in the first position and cannot rotate, the other valve plates 2 can still rotate to the second position to ensure the pressure relief function of the electromagnetic pressure relief valve.

[0059] For example, such as Figure 1As shown, the mesh-like limiting plate in valve seat 1 divides the inner cavity of valve seat 1 into three exhaust channels 11, which are arranged sequentially in the vertical direction. At this time, there are nine electromagnetic coils 3 arranged in an array. The nine electromagnetic coils 3 are connected in series in groups of three, and then in parallel to form the circuit topology. An external low-voltage power supply (e.g., 12V) powers the electromagnetic coils 3, with each electromagnetic coil 3 having an actual voltage of 4V. Due to the relatively high internal resistance of the coils, the total circuit current is less than 1A.

[0060] In some embodiments, such as Figure 3 and Figure 4 As shown, the electromagnetic pressure relief valve also includes a latch 6, which is connected to the valve seat 1 to secure the connecting wires of the electromagnetic coils 3. This ensures that the connecting wires of each electromagnetic coil 3 are reliably secured at specific positions on the valve seat 1, preventing the connecting wires from interfering with the rotation of the valve plate 2 and also preventing the connecting wires from encroaching on the exhaust passage 11.

[0061] For example, the latch 6 is attached to the back of the valve seat 1, and the latch 6 forms a U-shaped groove for the connecting wire harness to be fastened into.

[0062] The vehicle according to the present invention includes an electromagnetic pressure relief valve as described in any of the above embodiments.
