Solenoid valve structure, waist support structure and vehicle

Abstract

A solenoid valve structure, a waist support structure and a vehicle. The solenoid valve structure comprises a valve body, a first ferromagnetic member (2), an elastic member (3), and a second ferromagnetic member (4). The valve body is provided with a valve cavity (11), and an air inlet channel and an exhaust channel which can be communicated with the valve cavity (11). The first ferromagnetic member (2) and the second ferromagnetic member (4) are located in the valve cavity (11). The elastic member (3) is located between the first ferromagnetic member (2) and the second ferromagnetic member (4), and two ends of the elastic member (3) are respectively connected to the first ferromagnetic member (2) and the second ferromagnetic member (4). When the power-on state of the solenoid valve structure is changed, the first ferromagnetic member (2) can move towards or away from the second ferromagnetic member (4), so as to open the exhaust channel or the air inlet channel in the alternative only. Configuring the two ends of the elastic member (3) to be respectively connected to the first ferromagnetic member (2) and the second ferromagnetic member (4) prevents the problem that collision sound or abnormal sound is likely to be generated when the first ferromagnetic member (2) moves towards the second ferromagnetic member (4) and comes into contact with the elastic member (3) again, thereby improving the seat ride comfort.

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the China Patent Office on August 29, 2023, with application number 202322337140.5 and application name “Solenoid valve structure, lumbar support structure and vehicle”, all contents of which are incorporated by reference into this application. Technical Field

[0003] The present application relates to the field of vehicle technology, and in particular to a solenoid valve structure, a lumbar support structure, and a vehicle. Background Art

[0004] The solenoid valve structure can be used to control the inflation and deflation of the vehicle's waist support air bag waiting for inflation equipment.

[0005] Specifically, the solenoid valve structure includes a moving iron core, a fixed iron core, and a spring positioned between the two. One end of the spring is connected to the fixed iron core, while the other end of the spring abuts the moving iron core when the solenoid valve structure is powered off, pushing the iron core away from the fixed iron core to deflate the lumbar support airbag. When the solenoid valve structure is powered on, the moving iron core, under the influence of the magnetic attraction between the moving iron core and the fixed iron core, moves toward the fixed iron core, contacts the spring again, and compresses the spring to inflate the lumbar support airbag.

[0006] However, when the moving iron core reciprocates, when the moving iron core contacts the spring, collision sound and abnormal noise are generated between the moving iron core and the spring, which in turn affects the riding comfort of the seat.

[0025] The present application provides a solenoid valve structure, a lumbar support structure, and a vehicle. The solenoid valve structure includes a valve body, a first ferromagnetic member, an elastic member, and a second ferromagnetic member. The valve body has a valve cavity, with the first and second ferromagnetic members disposed within the valve cavity. The valve body has an intake passage and an exhaust passage that are communicable with the valve cavity. The elastic member is positioned between the first and second ferromagnetic members, with both ends of the elastic member connected to the first and second ferromagnetic members, respectively. The first ferromagnetic member can move toward or away from the second ferromagnetic member when the solenoid valve structure is energized, thereby selectively opening either the exhaust passage or the intake passage.

[0032] Detailed description

[0033] In order to more clearly understand the above-mentioned objectives, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0034] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application can also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present application, not all of the embodiments.

[0035] Example 1:

[0036] 1 and 2 , an embodiment of the present application provides a solenoid valve structure, including a valve body, a first ferromagnetic component 2 , an elastic component 3 and a second ferromagnetic component 4 .

[0037] The valve body has a valve cavity 11, and the first ferromagnetic member 2 and the second ferromagnetic member 4 are arranged in the valve cavity 11. The valve body has an air inlet channel and an air outlet channel that can communicate with the valve cavity 11.

[0038] The elastic part 3 is located between the first ferromagnetic part 2 and the second ferromagnetic part 4, and the two ends of the elastic part 3 are respectively connected to the first ferromagnetic part 2 and the second ferromagnetic part 4. The first ferromagnetic part 2 can move toward or away from the second ferromagnetic part 4 when the power-on state of the solenoid valve structure changes, so as to selectively open the exhaust channel or the intake channel.

[0039] In some embodiments, the inner cavity of the valve body can form a valve cavity 11, and the first ferromagnetic member 2 and the second ferromagnetic member 4 can be sequentially arranged in the valve cavity 11 along the length of the valve cavity 11. The elastic member 3 is located between the first ferromagnetic member 2 and the second ferromagnetic member 4, and the ends of the elastic member 3 are respectively connected to the first ferromagnetic member 2 and the second ferromagnetic member 4. When the power supply state of the solenoid valve structure changes, the first ferromagnetic member 2 can move toward or away from the second ferromagnetic member 4 to selectively open the exhaust channel or the intake channel.

[0040] In some embodiments, the first ferromagnetic part 2 can move toward or away from the second ferromagnetic part 4 when the power-on state of the solenoid valve structure changes, so that the process of selectively opening the exhaust channel or the intake channel can be specifically as follows: the first ferromagnetic part 2 can move toward the second ferromagnetic part 4 when the solenoid valve structure is powered on to close the exhaust channel and open the intake channel, so that air can be taken in through the intake channel; and the first ferromagnetic part 2 can move toward the direction away from the second ferromagnetic part 4 when the solenoid valve structure is powered off to close the intake channel and open the exhaust channel, so that exhaust can be discharged through the exhaust channel.

[0041] In some embodiments, the elastic member 3 is located between the first ferromagnetic member 2 and the second ferromagnetic member 4 and is connected to the first ferromagnetic member 2 and the second ferromagnetic member 4 respectively, so that no matter whether the first ferromagnetic member 2 moves toward the direction close to the second ferromagnetic member 4 or moves away from the second ferromagnetic member 4, the two ends of the elastic member 3 are always connected to the first ferromagnetic member 2 and the second ferromagnetic member 4 and are not separated. This can avoid the problem of easy collision sound or abnormal noise caused by the first ferromagnetic member 2 moving toward the direction close to the second ferromagnetic member 4 and contacting the elastic member 3 again, thereby improving the riding comfort of the vehicle seat.

[0042] In some embodiments, referring to the left and right directions of the drawings shown in FIG1 and FIG2 , the left end of the elastic member 3 is connected to the first ferromagnetic member 2, and the right end of the elastic member 3 is connected to the second ferromagnetic member 4. Referring to FIG1 , when power is turned on, the first ferromagnetic member 2 moves to the right under the action of the magnetic attraction between the first ferromagnetic member 2 and the second ferromagnetic member 4. At this time, the first ferromagnetic member 2 compresses the elastic member 3 and eventually presses against the second ferromagnetic member 4 to close the exhaust channel and open the inflation channel. Referring to FIG2 , when power is turned off, the first ferromagnetic member 2 moves to the left under the action of the elastic restoring force of the elastic member 3 and separates from the second ferromagnetic member 4. At this time, the first ferromagnetic member 2 eventually presses against the inner wall of the valve chamber 11 to close the inflation channel and open the exhaust channel.

[0043] In some embodiments, the elastic member 3 may be a spring. Furthermore, the two ends of the elastic member 3 may be welded to the first ferromagnetic member 2 and the second ferromagnetic member 4, respectively, or may be adhesively bonded or snap-fitted, as long as the two ends of the elastic member 3 are always connected to the first ferromagnetic member 2 and the second ferromagnetic member 4.

[0044] In some embodiments, a coil group can be wound on the outer wall of the valve body, and the coil group is electrically connected to the first ferromagnetic part 2 and the second ferromagnetic part 4, so that when the coil group is energized, the first ferromagnetic part 2 can move to the right under the magnetic attraction force of the first ferromagnetic part 2 and the second ferromagnetic part 4, and when the coil group is de-energized, the first ferromagnetic part 2 can move to the left under the action of the elastic restoring force of the elastic part 3.

[0045] The solenoid valve structure of the embodiment of the present application is such that the two ends of the elastic member 3 are respectively connected to the first ferromagnetic member 2 and the second ferromagnetic member 4. Therefore, no matter the first ferromagnetic member 2 moves toward the direction close to the second ferromagnetic member 4 or moves away from the second ferromagnetic member 4, the two ends of the elastic member 3 are always connected to the first ferromagnetic member 2 and the second ferromagnetic member 4 and do not separate. This can avoid the problem of the first ferromagnetic member 2 easily generating collision sounds or abnormal noises when it moves toward the direction close to the second ferromagnetic member 4 and contacts the elastic member 3 again, thereby improving the riding comfort of the vehicle seat.

[0046] In some embodiments, the two ends of the elastic member 3 can be respectively mounted on the first ferromagnetic member 2 and the second ferromagnetic member 4. Compared with the manner in which the two ends of the elastic member 3 are respectively connected to the side surfaces of the first ferromagnetic member 2 and the second ferromagnetic member 4 facing each other, when the two ends of the elastic member 3 are respectively mounted on the first ferromagnetic member 2 and the second ferromagnetic member 4, it is convenient for the first ferromagnetic member 2 to compress the part of the elastic member 3 that is not mounted on the first ferromagnetic member 2 and the second ferromagnetic member 4 when the first ferromagnetic member 2 moves to the right, and then press against the second ferromagnetic member 4, that is, the amount of compression of the elastic member 3 by the first ferromagnetic member 2 can be reduced.

[0047] As shown in Figure 1, in some embodiments, the side wall of the first ferromagnetic part 2 at one end facing the second ferromagnetic part 4 is recessed toward the central axis of the valve cavity 11 to form a first annular groove 21, and part of the elastic part 3 is located in the first annular groove 21.

[0048] In some embodiments, in order to facilitate the installation of the elastic part 3, the side wall of the right end of the first ferromagnetic part 2 can be set to be recessed in the direction close to the central axis of the valve chamber 11 to form a first annular groove 21. At this time, a step structure is formed between the part of the first ferromagnetic part 2 that does not form the first annular groove 21 and the part of the first ferromagnetic part 2 that forms the first annular groove 21. The elastic part 3 is located in the first annular groove 21 and can be pressed against the step structure to limit or install the elastic part 3.

[0049] As shown in FIG1 , in some embodiments, the outer wall of the elastic member 3 does not protrude beyond the outer wall of the first ferromagnetic member 2 , thereby avoiding the problem of the elastic member 3 protruding beyond the outer wall of the first ferromagnetic member 2 and occupying space in the valve cavity 11 . For example, the outer wall of the elastic member 3 can be flush with the outer wall of the first ferromagnetic member 2 , thereby making the overall appearance relatively flat and beautiful; alternatively, the outer wall of the elastic member 3 can be lower than the outer wall of the first ferromagnetic member 2 .

[0050] As shown in Figure 1, in some embodiments, the side wall of the second ferromagnetic part 4 at one end facing the first ferromagnetic part 2 is recessed toward the center axis of the valve cavity 11 to form a second annular groove 42, and a portion of the elastic part 3 is located in the second annular groove 42.

[0051] In some embodiments, in order to facilitate the installation of the elastic part 3, the side wall of the left end of the second ferromagnetic part 4 can be set to be recessed in the direction close to the central axis of the valve chamber 11 to form a second annular groove 42. At this time, a step structure is formed between the part of the second ferromagnetic part 4 that does not form the second annular groove 42 and the part of the second ferromagnetic part 4 that forms the second annular groove 42. The elastic part 3 is located in the second annular groove 42 and can be pressed against the step structure to limit or position the elastic part 3.

[0052] As shown in FIG1 , in some embodiments, the outer wall of the elastic member 3 does not protrude beyond the outer wall of the second ferromagnetic member 4 , thereby avoiding the problem of the elastic member 3 protruding beyond the outer wall of the second ferromagnetic member 4 and occupying space in the valve cavity 11 . For example, the outer wall of the elastic member 3 can be flush with the outer wall of the second ferromagnetic member 4 , thereby making the overall appearance relatively flat and beautiful; alternatively, the outer wall of the elastic member 3 can be lower than the outer wall of the second ferromagnetic member 4 .

[0053] 1 and 2 , in some embodiments, the valve body includes a valve housing 1 and a valve seat 8, a valve cavity 11 is opened in the valve housing 1, the valve seat 8 is located at the open end of the valve housing 1, and the valve seat 8 has a vent hole 81 connected to the outside, and the valve housing 1 has a first opening 12 and a second opening connected to the valve cavity 11, the first opening 12 is used to communicate with an external inflation device, and the second opening is used to communicate with the device to be inflated.

[0054] The first opening 12, the valve cavity 11 and the second opening are connected to form an air inlet passage for inflating the inflatable device. The vent hole 81, the valve cavity 11 and the second opening are connected to form an air exhaust passage for exhausting the inflatable device.

[0055] In some embodiments, the elastic member 3 is located between the first ferromagnetic member 2 and the second ferromagnetic member 4 and the two ends of the elastic member 3 are respectively connected to the first ferromagnetic member 2 and the second ferromagnetic member 4; the first ferromagnetic member 2 can move toward the direction close to the second ferromagnetic member 4 and block the air vent 81 when the solenoid valve structure is energized. At this time, the exhaust channel is in a closed state, and the first opening 12, the valve cavity 11 and the second opening are connected to form an air intake channel for inflating the equipment to be inflated; and the first ferromagnetic member 2 can move toward the direction away from the second ferromagnetic member 4 and block the first opening 12 under the action of the elastic member 3 when the solenoid valve structure is de-energized. At this time, the air intake channel is in a closed state, and the air vent 81, the valve cavity 11 and the second opening are connected to form an exhaust channel for exhausting the equipment to be inflated.

[0056] In some embodiments, a first pipeline 6 and a second pipeline 7 can be connected to the valve housing 1, the first pipeline 6 being in communication with the external inflation device and the first opening 12, respectively, and the second pipeline 7 being in communication with the second opening and the device to be inflated, respectively. When the first ferromagnetic component 2 blocks the vent 81, the external inflation device can input gas through the first pipeline 6, and the gas entering the first pipeline 6 enters the device to be inflated through the first opening 12, the valve cavity 11, and the second opening, thereby achieving the inflation operation of the device to be inflated. When the first ferromagnetic component 2 blocks the first opening 12, the gas in the device to be inflated can enter the valve cavity 11 through the second pipeline 7 and the second opening, and then be discharged through the vent 81, thereby achieving the exhaust operation of the device to be inflated.

[0057] In some embodiments, a central hole 41 communicating with the vent 81 can be provided on the second ferromagnetic member 4. When the first ferromagnetic member 2 blocks the first opening 12, gas within the device to be inflated can enter the valve cavity 11 through the second pipeline 7 and the second opening, and then be discharged through the central hole 41 and the vent 81, thereby achieving exhaust operation of the device to be inflated. When the first ferromagnetic member 2 blocks the central hole 41 and thus blocks the vent 81, an external inflatable device can input gas through the first pipeline 6, and the gas entering the first pipeline 6 can enter the device to be inflated through the first opening 12, the valve cavity 11, and the second opening, thereby achieving inflation operation of the device to be inflated.

[0058] In some embodiments, referring to the left-right direction of the drawings shown in FIG1 and FIG2 , the first ferromagnetic member 2 is positioned to the left of the second ferromagnetic member 4, and the first opening 12 and the second opening are positioned to the left of the valve housing 1. In this case, an opening communicating with the valve cavity 11 can be provided on the right side of the valve housing 1, thereby facilitating installation of the first ferromagnetic member 2 and the second ferromagnetic member 4 into the valve cavity 11 through the opening.

[0059] At this time, as shown in Figure 1, when the first ferromagnetic part 2 moves toward the direction close to the second ferromagnetic part 4 until the first ferromagnetic part 2 is against the second ferromagnetic part 4 and blocks the middle hole 41 to block the air vent 81, that is, when the first ferromagnetic part 2 moves to the right to block the middle hole 41 to block the air vent 81, the left side of the first ferromagnetic part 2 is separated from the first opening 12, and the first opening 12 is no longer blocked. At this time, the first opening 12, the valve cavity 11 and the second opening are connected to form an air intake channel, while the second opening, the valve cavity 11 and the air vent 81 cannot be connected to form an exhaust channel. At this time, the gas can be transported to the device to be inflated through the air intake channel through an external inflation device to realize the inflation operation of the device to be inflated. The inflation path during inflation can be shown as the dotted arrow shown in Figure 1.

[0060] In some embodiments, as shown in Figure 2, when the first ferromagnetic part 2 moves in a direction away from the second ferromagnetic part 4 until the first ferromagnetic part 2 is against the left side wall of the valve housing 1 to block the first opening 12, that is, when the first ferromagnetic part 2 moves to the left and blocks the first opening 12, the right side of the first ferromagnetic part 2 is separated from the second ferromagnetic part 4, thereby no longer blocking the air vent 81. At this time, the first opening 12 cannot be connected with the valve cavity 11 and the second opening to form an air intake channel, while the second opening, the hole 41 in the valve cavity 11 and the air vent 81 are connected to form an exhaust channel. At this time, the gas in the equipment to be inflated can be discharged through the exhaust channel to realize the exhaust operation of the equipment to be inflated. The exhaust path during exhaust can be shown as the dotted arrow shown in Figure 2.

[0061] In some embodiments, the external inflatable device may be, for example, an air pump or other inflatable device. The device to be inflated may be, for example, a waist support airbag or an airbag, etc., which needs to be inflated or deflated.

[0062] In some embodiments, the first ferromagnetic component 2 and the second ferromagnetic component 4 can both be made of an iron core or a ferromagnetic material. For example, the first ferromagnetic component 2 can be a first iron core made of an iron core, and the second ferromagnetic component 4 can be a second iron core made of an iron core.

[0064] In some embodiments, when the first ferromagnetic component 2 is located to the left of the second ferromagnetic component 4, a first buffer component 51 may be provided on the right side of the first ferromagnetic component 2, so that when the first ferromagnetic component 2 moves to the right and contacts the second ferromagnetic component 4, the first buffer component 51 can buffer the contact and collision between the two components, and the first buffer component 51 can block the vent 81 of the second ferromagnetic component 4. Furthermore, a second buffer component 52 may be provided on the left side of the first ferromagnetic component 2, so that when the first ferromagnetic component 2 moves to the left and contacts the left inner wall of the valve housing 1, the second buffer component 52 can buffer the contact and collision between the two components, and the second buffer component 52 can block the first opening 12.

[0065] In some embodiments, the first buffer member 51 and the second buffer member 52 can both be rubber buffer pads or silicone buffer pads or buffer members made of other elastic and flexible materials.

[0066] 1 and 2 , in some embodiments, when a first buffer member 51 is provided on the first ferromagnetic member 2 , a first recess 22 is provided on a side of the first ferromagnetic member 2 facing the second ferromagnetic member 4 , and the first buffer member 51 is provided in the first recess 22 and a portion of the first buffer member 51 is located outside the first recess 22 .

This allows the first buffer member 51 to be installed on the first ferromagnetic member 2 and effectively reduces the space occupied by the first buffer member 51 within the valve chamber 11. In addition, the first buffer member 51 can be adapted to the first recessed groove 22, thereby ensuring that the first buffer member 51 can be securely assembled within the first recessed groove 22.

This allows the second buffer member 52 to be installed on the first ferromagnetic member 2 and effectively reduces the space occupied by the second buffer member 52 within the valve chamber 11. In addition, the second buffer member 52 can be adapted to the second recessed groove 23, thereby ensuring that the second buffer member 52 can be securely assembled within the second recessed groove 23.
