Description

Technical Field

[0001] The invention belongs to the technical field of ventilation frames, and in particular relates to an active ventilation frame device for an automobile. Background Art

[0002] The exchange of air between the inside and outside of a car is currently usually achieved in the following two ways: 1. By opening the car windows or doors, 2. By exchanging air with the outside through the ventilation frame installed on the car body. However, both of the above methods require air exchange only after the air pressure difference between the inside and outside environments of the car rises to a certain level. Correspondingly, the ventilation frame blades can only remain open under the pressure of the air inside the car, thereby achieving air pressure relief.

[0003] However, with the rapid development of the automobile industry in recent years, automobile configurations and functions have gradually become richer. In the face of more and more rich automobile configurations, its single function is increasingly unable to meet the needs of automobiles. For example, in similar working conditions such as automobile oxygen production and wading navigation, the interior environment of the vehicle must always be isolated from the exterior environment, and the above-mentioned traditional ventilation frames can no longer meet the operational requirements of sealing use.

[0004] In view of this, overcoming the defects of the above-mentioned prior art is an urgent problem to be solved in the field of this technology. Summary of the invention

[0005] In view of the above problems, the present invention proposes an active ventilation frame device for an automobile, comprising: a ventilation frame frame and baffle blades;

[0007] The annular electromagnetic coil is connected to an external power source.

[0008] Furthermore, it also includes a plurality of hanging rod bodies, one end of which is connected above the front port of the string of air holes, the hanging rod body includes a hanging part and a cross-blocking part, the baffle blades are provided with hanging openings corresponding to the hanging rod bodies, the hanging openings are sleeved on the outer wall of the hanging part, and the cross-sectional area of ​​the hanging openings is smaller than the cross-sectional area of ​​the cross-blocking part.

[0009] Furthermore, the baffle blade is made of a flexible material, and the baffle blade includes an upper baffle portion and a lower baffle portion, and the upper baffle portion is sleeved with the suspension rod body;

[0010] The magnetic metal sheet comprises a first metal strip and a second metal strip. The first metal strip and the second metal strip are respectively embedded in the upper baffle portion and the lower baffle portion, and a predetermined distance is maintained between the first metal strip and the second metal strip.

[0011] Furthermore, the upper baffle portion abuts against the front end of the string of air holes to form a fixed connection.

[0012] Furthermore, the first metal strip and the second metal strip are arranged in a counterposition, and the first metal strip and the second metal strip extend in the same direction along the side wall of the baffle blade.

[0013] Furthermore, the cross sections of the ventilation holes, the air string holes, and the baffle blades all adopt the same structure.

[0014] Furthermore, the lower end and the upper end of the front port of the air string hole are arranged front and back, so that the baffle blades are arranged obliquely when blocking the air string hole.

Combined with the magnetic metal sheet embedded in the baffle blade and arranged in opposition to the annular electromagnetic coil, the annular electromagnetic coil generates an adsorption force on the magnetic metal sheet, driving the baffle blade to fit the port of the air hole, thereby sealing the air hole, and further isolating the gas flow between the inside and outside of the vehicle, greatly improving the overall service life of the device and ensuring the technical requirement for timely sealing of the ventilation frame.

DETAILED DESCRIPTION

[0027] The following description provides many different embodiments or examples for implementing different features of the present invention. The components and arrangements described in the following specific examples are only used to simplify the present invention and are only used as examples, not to limit the present invention.

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] The present invention provides an automobile active ventilation frame device. Figure 1 A schematic diagram showing an active ventilation frame device for an automobile in an embodiment of the present invention Figure 1 , Figure 1 In the invention, the automobile active ventilation frame device comprises: a ventilation frame frame 1 and baffle blades 2;

[0030] The ventilation frame skeleton 1 is provided with a ventilation hole 3 connecting the space inside the vehicle and the space outside the vehicle, and a plurality of array-arranged string air holes 4 are arranged inside the ventilation hole 3, and an annular electromagnetic coil 5 is embedded around the front ports of the plurality of string air holes 4 facing the external environment, and a baffle blade 2 is provided at the front ports of the plurality of string air holes 4, and a magnetic metal sheet 6 arranged in correspondence with the annular electromagnetic coil 5 is embedded inside the baffle blade 2;

[0031] The annular electromagnetic coil 5 is connected to an external power source. When the annular electromagnetic coil 5 is energized, it generates an adsorption force to adsorb the magnetic metal sheet 6, thereby achieving the blocking of the front end of the air string hole 4 by the baffle blade 2.

[0032] The automobile active ventilation frame device of the present application, in actual use, controls the start and stop of the annular electromagnetic coil 5 through an external power supply. When the annular electromagnetic coil 5 is energized, the annular electromagnetic coil 5 forms a coaxial magnetic induction effect at the corresponding air hole 4. Combined with the magnetic metal sheet 6 embedded in the baffle blade 2 and arranged in opposition to the annular electromagnetic coil 5, the annular electromagnetic coil 5 generates an adsorption force on the magnetic metal sheet 6, driving the baffle blade 2 to fit the port of the air hole 4, thereby blocking the air hole 4, and further isolating the gas flow between the inside and outside of the vehicle.

[0033] In addition, considering the use of automobiles in similar complex environments such as wading and sailing, in actual use, impurities and debris such as sand, leaves, etc. in the air often gather at the front port of the air hole 4, and even directly affect the internal transmission structure through the air hole 4, resulting in abnormal operation of the structure, which directly affects the operation requirement of the baffle blade 2 to block the air hole. The present application uses the magnetic induction effect generated by the annular electromagnetic coil 5 as the driving component for the baffle blade 2, avoiding the problems of jamming and blockage that may be caused by connecting parts such as mechanical transmission shafts, greatly improving the service life of the device, and ensuring the technical requirement for timely sealing of the ventilation frame.

[0034] It should be noted that, in the present embodiment, the external power source is the current and voltage of the annular electromagnetic coil 5, and the specifications of the annular electromagnetic coil 5, which need to be matched and calculated according to the application scenario and vehicle model requirements to ensure the effective closure of the ventilation frame structure under specific working conditions.

[0035] It also includes a plurality of hanging rod bodies 7, one end of which is connected to the top of the front end of the string of air holes 4, and the hanging rod body 7 includes a hanging portion and a cross-blocking portion. The baffle blade 2 is provided with a hanging opening 23 corresponding to the hanging rod body 7, and the hanging opening 23 is sleeved on the outer wall of the hanging portion, and the cross-sectional area of ​​the hanging opening 23 is smaller than the cross-sectional area of ​​the cross-blocking portion, so as to limit the activity range of the baffle blade 2 and prevent the baffle blade 2 from detaching from the cross-blocking portion.

[0036] In the present application, the baffle blade 2 is suspended by the suspension rod body 7 through the suspension part and the suspension opening 23, and the activity range of the baffle blade 2 is limited by the cross-blocking part. When the annular electromagnetic coil 5 is in a power-off state, the baffle blade 2 is suspended on the suspension rod body 7, and the baffle blade 2 swings on the suspension rod body 7 along with the gas flow on both sides of the air hole 4, thereby autonomously blocking and opening the air hole 4.

[0037] refer to Figure 2 In the example shown, the baffle blade 2 includes an upper baffle portion 21 and a lower baffle portion 22, the upper baffle portion 21 is sleeved with the suspension rod 7, the magnetic metal sheet 6 includes a first metal strip 61 and a second metal strip 62, the upper baffle portion 21 and the lower baffle portion 22 are respectively embedded with the first metal strip 61 and the second metal strip 62, and a predetermined distance is maintained between the first metal strip 61 and the second metal strip 62.

[0038] Among them, the baffle blades 2 are made of flexible material, the upper baffle part 21 is played by the first metal strip 61 which plays the role of the skeleton, and the lower baffle part 22 is played by the second metal strip 62 which plays the role of the skeleton. Because a predetermined distance is maintained between the first metal strip 61 and the second metal strip 62, the angle between the upper baffle part 21 and the lower baffle part 22 can be flexibly changed.

[0039] refer to Figure 3 and Figure 4 , indicating that when the annular electromagnetic coil 5 is in the power-off state, based on the pressure difference between the environment inside the vehicle and the environment outside the vehicle, it is affected by the airflow passing through the string air hole 4, driving the baffle blade 2 to swing along the movement trajectory of the airflow; illustratively, a baffle blade 2 is installed at each string air hole 4, and the multiple baffle blades 2 in the figure correspond to the baffle blades 2 in different swinging states respectively; through the swing of the baffle blade 2, the blocking area of ​​the airflow is changed, thereby reducing the obstruction of the baffle blade 2 to the gas flow in the string air hole 4.

[0040] At the same time, the upper baffle portion 21 abuts against the front end of the air string hole 4 and forms a fixed connection. For example, it is bonded with glue or fixed with screws to prevent the baffle blade 2 from sliding on the hanging portion of the hanging rod body 7, thereby reducing the wear of the upper baffle portion 21 and the hanging rod body 7 and improving the overall service life of the baffle blade 2.

[0041] Correspondingly, the first metal strip 61 and the second metal strip 62 are arranged in a counterposition, and the first metal strip 61 and the second metal strip 62 extend in the same direction along the side wall of the baffle blade 2, so that the first metal strip 61 and the second metal strip 62 form an encircling state. Exemplarily, the first metal strip 61 and the second metal strip 62 both adopt a C-shaped structure and are arranged in a counterposition, ensuring that the baffle blade 2 is driven as a whole to form a blockage with the string air hole 4; in the process of selecting and manufacturing the first metal strip 61 and the second metal strip 62, the first metal strip 61 and the second metal strip 62 are made of iron and / or cobalt and / or nickel based on lightness and high magnetic attraction.

[0042] Among them, reference Figure 5 and Figure 2 , four string air holes 4 are arranged in an array in the ventilation holes 3, and three groups of suspension rods 7 are arranged at the front ends of the string air holes 4 to improve the stability of the baffle blades 2 suspended on the suspension rods 7. At the same time, in order to improve the integrity of the ventilation holes 3, the string air holes 4 and the baffle blades 2, the cross-sections of the ventilation holes 3, the string air holes 4 and the baffle blades 2 all adopt the same structure. For example, the cross-sections of the ventilation holes 3, the string air holes 4 and the baffle blades 2 all adopt a rectangular structure, and the turning points of the magnetic metal sheets 6 and the annular electromagnetic coils 5 adopt rounded transitions to ensure the compactness of adjacent string air holes 4 after the array of several string air holes 4 is arranged, and to ensure that each baffle blade 2 is suspended by at least two suspension rods 7 to meet the stability requirements of the baffle blades 2 suspended on the suspension rods 7.

[0043] It should be noted that, although the above description is given by taking four air holes 4 and three groups of suspension rods 7 as an example, the present invention is not limited thereto, and the number of air holes 4 and suspension rods 7 can be in various forms. The spacing between adjacent air holes 4 and adjacent baffle blades 2 can also be in various forms. Those skilled in the art can comprehensively consider the driving principle of the present invention and the actual application situation, as long as the principle of the present invention can be realized.

[0044] Among them, Figure 4 In the example shown, the lower end and the upper end of the front port of the air hole 4 are arranged front to back, so that the baffle blades 2 are arranged obliquely when blocking the air hole 4. Compared with the vertical surface structure of the front port of the air hole 4, the oblique arrangement of the baffle blades 2 of the present application increases the connection area between the baffle blades 2 and the front port of the air hole 4, and the baffle blades 2 have a force acting downward and toward the front port of the air hole 4 in a naturally placed state, so as to improve the stability when the front port of the air hole 4 and the baffle blades 2 form abutment.

[0045] exist Figure 5In the example shown, when the annular electromagnetic coil 5 is in the power-off state and the air pressure inside and outside the vehicle is the same, the upper baffle portion 21 of the baffle blade 2 overlaps the upper end of the front port, and the lower baffle portion 22 of the baffle blade 2 overlaps the lower end of the front port, and the baffle blade 2 is placed at an angle; when the air pressure inside the vehicle is greater than the air pressure outside the vehicle, the lower baffle portion 22 is separated from the lower end of the front port, and as the pressure difference between the inside and outside of the vehicle increases, the gap between the lower baffle portion 22 and the lower end of the front port gradually increases.

[0046] When the air pressure outside the vehicle is greater than the air pressure inside the vehicle, or the annular electromagnetic coil 5 is in a powered state, the baffle blade 2 fits against the front end of the air string hole 4 .

[0047] Taking the integrity of the device into consideration, the front end of the air string hole 4 is located in the inner cavity of the ventilation hole 3, while meeting the protection requirements of the ventilation hole 3 for the baffle blades 2.

[0048] In order to increase the force area of ​​the baffle blade 2 against the air hole 4, a support plate 8 coplanar with the front end of the air hole 4 is provided in the air hole 4 to improve the stability of the placement of the baffle blade 2. At the same time, the area of ​​the baffle blade 2 is larger than the cross-sectional area of ​​the air hole 4 to ensure that the baffle blade 2 fully covers the air hole 4.

[0049] In order to increase the sealing performance of the baffle blade 2 on the air hole 4, a sealing ring or a sealing groove is added to the front port of the air hole 4, or a sealing ring or a sealing protrusion is added to the side wall of the baffle blade 2 facing the air hole 4. These are conventional technical solutions known to technical personnel in the field and will not be explained here. In actual use, the electromagnetic force is used to provide the baffle blade 2 with a force attached to the front port of the air hole 4, which has met the technical requirement of blocking the air hole 4.

[0050] In addition, in the present embodiment, in order to improve the practicality of the device of the present application, a plurality of annular electromagnetic coils 5 are respectively connected in parallel with an external power supply through a plurality of cables 9 in a one-to-one correspondence, and each annular electromagnetic coil 5 is individually regulated by the external power supply to meet various blocking operation requirements, thereby blocking one or more specific air string holes 4, and at the same time ensuring that the unobstructed flow of other air string holes 4 is not affected by the corresponding baffle blades 2.

[0051] During actual use, in order to improve the active sealing effect of the existing ventilation frame, the annular electromagnetic coil 5 can be directly installed on the existing ventilation frame, and the existing ordinary blades can be replaced with the baffle blades 2 of the present application, and the annular electromagnetic coil 5 can be connected to the corresponding vehicle-mounted circuit system or a power supply can be installed, which is convenient and practical.
