Description

Technical Field

[0001] This application relates to the field of automotive ventilation technology, specifically to a fan suspension mechanism, a seat ventilation system, and an automotive seat. Background Technology

[0002] With the development of the vehicle transportation sector, people's requirements for vehicle ride comfort are getting higher and higher, and the application of seat ventilation devices is becoming more and more widespread. However, due to the limited space in the back and bottom of car seats, the space for ventilation components such as fans is tight and cannot be arranged reasonably. Therefore, the size of ventilation components needs to be reduced as much as possible to meet the seat space requirements, but the reduction in size will inevitably affect the ventilation performance. For example, the fan connection structure disclosed in the published "Fan Connection Structure and Car Seat" 202010580820.8 is directly connected to the bottom surface of the seat foam without being squeezed into the foam. In order to make full use of the space under the seat, technical improvements are needed. Therefore, the reasonable use of the space under the seat to complete the arrangement of comfort performance components has become an urgent problem to be solved. Summary of the Invention

[0031] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] Example 1

[0034] As mentioned in the background section, in view of the problems in the prior art, this application proposes a fan suspension mechanism, which is mounted on a support frame, such as... Figure 1 As shown, it includes:

[0035] A first mounting base 1 is connected to the support frame. The first mounting base 1 has a first mounting surface 101 and a first through hole 102 in the middle. The axis of the first through hole 102 is a first direction. Optionally, the first mounting base 1 can be circular, square, rectangular, elliptical, or oblong, etc. The first mounting surface 101 is the top surface of the first mounting base 1, and the first direction is a vertical direction. In addition, the first mounting base 1 can be screwed or welded to the support frame.

[0036] A connecting assembly includes at least one connector, each connector having a first end and a second end. The first end is connected to the first mounting base 1, and the second end has a first boss 201 extending in a second direction, which is perpendicular to the first direction. Optionally, the first end is the bottom end of each connector, and the second end is the top end of each connector. The shape and quantity of the connecting assembly can be changed or increased / decreased according to usage.

[0037] The connecting component forms a first space with the first mounting base 1 and the first boss 201. The first space is used to accommodate part or all of the fan 8. One end of the fan 8 is connected to each of the first bosses 201. When the connecting component is deformed by pressure towards the first mounting base 1, the distance between it and the first mounting base 1 shortens. When the pressure disappears, the connecting component returns to its initial state, and the distance between it and the first mounting base 1 also returns to its initial state. In certain specific scenarios, such as... Figure 7 As shown, when a person sits on seat 6, a downward pressure is applied to seat 6. At this time, the connecting component deforms and can drive the fan 8 to move downward. In use, the fan 8 in this mechanism can be displaced with the deformation of the connecting component, which can avoid the feeling of foreign objects when the passenger sits, and also improve the space utilization and avoid reducing the size of the fan 8.

[0038] Furthermore, the connecting component has a flexible structure and is made of polypropylene.

[0039] Furthermore, such as Figure 1 As shown, the connectors are arranged in a circumferential array on the first mounting base 1, and each connector forms a first angle with the first mounting surface 101. The opening direction of the first angle is consistent, all facing away from the first mounting surface 101. Further, the first bosses 201 at the second end of each connector are interconnected to form a first protrusion 2. In certain specific scenarios, the first protrusion 2 is annular, and its bottom is welded to the top of each connector. Optionally, the connector can be a first inclined spring 3, the bottom of which is connected to the first mounting base 1. The first boss 201 connected to the top of each first inclined spring 3 is provided with a first hook hole 301, and one end of the fan 8 can be inserted into the first hook hole 301. When a person sits on the seat 6 and generates downward pressure, the end away from the first mounting base 1 drives the fan 8 to move downward. Figure 2 As shown, the inclined structure of the first inclined spring 3, the deformation at its connection with the first mounting base 1 and the first boss 201, and its elasticity enable it to have a downward displacement, which can prevent the fan 8 from being squeezed and damaged.

[0040] Specifically, when the first protrusion 2 is annular, the angle between the first inclined spring piece 3 and the plane where the first mounting base 1 is located is the first angle, which is less than 90 degrees and not perpendicular to the plane where the first mounting base 1 is located; furthermore, each of the first inclined spring pieces 3 gradually tilts towards the center of the outer contour of the first mounting base 1 from the first end to the second end, and its tilt angle is less than 90 degrees.

[0041] Furthermore, the projection of the first inclined spring piece 3 onto the plane where the first mounting base 1 is located is the first projection, the line connecting the bottom end of the first inclined spring piece 3 to the first line is the first connecting line, and the angle formed by the side of the first projection closest to the center of the outer contour and the first connecting line is the fourth angle, which is less than 90 degrees.

[0042] Furthermore, such as Figure 4 As shown, the connectors are arranged in a circumferential array on the first mounting base 1, and the extension direction of each connector forms a second angle with the first mounting surface 101. The opening direction of each second angle faces the axis of the first through hole 102. Optionally, the connector can be a second inclined spring 4. The bottom end of each second inclined spring 4 is welded to the first mounting base 1, and the first boss 201 connected to the top of each second inclined spring 4 is provided with a second mounting hole 401. One end of the fan 8 can be inserted into the second mounting hole 401. Specifically, the middle of each second inclined spring 4... The projection of the line onto the plane formed by the centerline and the axis and the projection of the first mounting seat 1 onto this plane form the second angle, which is less than 90 degrees. When a person sits on the seat 6 and generates downward pressure, the end away from the first mounting seat 1 drives the fan 8 to move downward, which can prevent the fan 8 from being squeezed and damaged. In certain specific scenarios, the number can be four. The four second oblique springs 4 are equally spaced on the first mounting surface 101, which can ensure that the fan 8 does not deviate when it moves downward, and always moves in the vertical direction, which can ensure the comfort of the passenger.

[0043] Furthermore, such as Figure 5As shown, the connectors are arranged in a circumferential array on the first mounting base 1. The extension direction of each connector forms a third angle with the first mounting surface 101. The opening direction of each third angle faces the axis of the first through hole 102. Each connector has a second through hole near the end of the first mounting surface 101. Optionally, the connector can be a third inclined spring piece 5. The first mounting base 1 can be square. The bottom end of each third inclined spring piece 5 is welded to the four right angles of the first mounting base 1. The first boss 201 connected to the top of each third inclined spring piece 5 has a third hook hole 501. One end of the fan 8 can be inserted into the third mounting hole 501; specifically, the projection of the centerline of each of the third inclined spring pieces 5 onto the surface formed by the centerline and the axis and the projection of the first mounting seat 1 onto this surface form the third angle, which is less than 90 degrees; when a person sits on the seat 6 and generates downward pressure, the end away from the first mounting seat 1 drives the fan 8 to move downward, which can prevent the fan 8 from being squeezed and damaged; in certain specific situations, the split structure of the third inclined spring piece 5 can make it more stable when it drives the fan 8 to move downward, which can prevent the fan 8 from being squeezed and damaged.

[0044] Furthermore, the fan suspension mechanism and the support frame can be integrated or separate; further, such as Figure 6 As shown, the support frame includes a first frame 601 and / or a second frame 701. The first frame 601 is located at the bottom of the seat 6, and the second frame 701 is located on the side of the seat back 7 away from the human body. In certain specific scenarios, such as... Figure 8 As shown, the fan suspension mechanism can be a separate structure from the first frame 601 and / or the second frame 701 and can be detachably connected to the first frame 601 and / or the second frame 701, or it can be integrally injection molded with the first frame 601 and / or the second frame 701. When a person sits on the seat 6, pressure is applied to the seat 6 and the seat back 7 respectively, causing the fan suspension mechanism provided on the first frame 601 and the second frame 701 to drive the fan 8 to move, which can prevent the fan 8 from being squeezed and damaged, and also prevent the passenger from feeling a foreign object.

[0045] Furthermore, the connection strength between the connector and the first boss 201 is greater than the connection strength between the connector and the first mounting base 1. In certain specific scenarios, when a person sits on the seat 6, the connector deforms, causing the first boss 201 and the fan 8 to move downwards. The connection between the connector and the first boss 201 hardly deforms, and the deformation mainly occurs at the connection between the connector and the first mounting base 1. This ensures that the fan 8 moves downwards more stably, improves riding comfort, and also improves the durability of the fan suspension mechanism.

[0046] Example 2

[0047] Based on Embodiment 1, this application further proposes a seat ventilation system, which includes the aforementioned fan suspension mechanism; the seat ventilation system also includes a ventilation component 9, and the air inlet or outlet of the fan 8 is connected to the airflow path of the ventilation component 9; the fan 8 can be connected to the fan suspension mechanism by any of the following methods: plug-in, rotary snap-fit, rubber rivet, and self-tapping screw; in certain specific scenarios, the connection form between the fan 8 and the first boss 201 can be various; one end of the ventilation component 9 located at the bottom of the seat 6 abuts against the first bracket, and the end away from the first bracket abuts against the end of the first boss 201 away from the connector. Next, the ventilation component 9 is used to circulate air within the seat 6; one end of the ventilation component 9, located on the side of the seat back 7 away from the human body, abuts against the second bracket, and the end away from the second bracket abuts against the end of the first protrusion 201 away from the connector; optionally, the ventilation component 9 is an air bag, the top of which is in close contact with the first bracket and / or the second bracket. When the seat ventilation system is in suction mode, air can enter the seat 6 and the seat back 7 through the air bag, and then be discharged through the holes on the surface of the seat 6 and the seat back 7, which can ensure the ventilation performance of the seat 6 and the seat back 7, thereby improving the comfort of the occupant.

[0048] Example 3

[0049] Based on Embodiments 1 and 2, this application further proposes a car seat, such as... Figure 9 As shown, the car seat includes the aforementioned seat ventilation system and also includes a first seat foam 602 disposed at the bottom of the seat 6. The ventilation component 9 is disposed between the first seat foam 602 and the first frame 601, and the fan suspension mechanism is connected to the first frame 601. In certain specific scenarios, the first seat foam 602 is made of polyurethane material, and its bottom end can be squeezed to increase the usable space at the bottom of the seat 6.

[0050] Furthermore, this application proposes a car seat, which includes the aforementioned seat ventilation system and a second seat foam 702 disposed on the seat back 7. The ventilation component is disposed between the second seat foam 702 and the second frame 701 for circulating air within the car seat. The second frame 701 may be a back spring or a lumbar support backplate, and the fan suspension mechanism may be connected to the back spring or the lumbar support backplate. The second seat foam 702 is made of polyurethane material and can be compressed on the side away from the human body, thereby increasing the usable space of the seat back 7.

[0051] In addition, in practical application scenarios, the ventilation component 9 may be provided only between the first seat foam 602 and the first frame 601, or only between the second seat foam 702 and the second frame 701. Alternatively, the ventilation component 9 may be provided between the first seat foam 602 and the first frame 601, and between the second seat foam 702 and the second frame 701. The specific installation can be changed according to different vehicle models and usage scenarios.
