Description

Technical Field

[0001] This application relates to the field of automotive interior accessories, and in particular to automotive seat fan assemblies, automotive cushions, and automotive seats. Background Technology

[0002] Car seat fans are installed on car seats, and traditional car seat fans use a single air outlet design. Because there's only one outlet, the airflow from a traditional car seat fan has a relatively limited coverage area, making it difficult to provide even and effective ventilation and cooling across the entire seat surface. For example, for some larger areas like the seat cushion and backrest, the airflow from a single-outlet fan may only provide good cooling to that specific area, while areas further away from the outlet will still experience heat buildup, resulting in a lack of overall thermal comfort for the seat.

[0003] Specifically, single-outlet fans cannot meet the needs of applications requiring a large air volume or simultaneous airflow in two different directions. Moreover, the unidirectional airflow of a single-outlet fan can lead to uneven air distribution within the space.

[0004] Traditional car seat ventilation systems also use a combination of multiple single-outlet fans. However, due to problems such as the coordination between the fans and unreasonable outlet layout, uneven ventilation can easily occur, resulting in uneven airflow distribution on the car seat surface. Some areas may experience excessively strong or weak airflow, affecting the thermal comfort of the car seat. Utility Model Content

[0053] This application discloses an automotive seat fan assembly, an automotive seat cushion, and an automotive seat, which include some or all of the technical features of the following embodiments; that is, the automotive seat fan assembly, automotive seat cushion, and automotive seat include some or all of the following structures. In one embodiment of this application, an automotive seat fan assembly includes a housing, a drive motor, a fan wheel assembly, and a bearing component; the housing has a receiving cavity and a first air outlet, a second air outlet, and an air inlet respectively communicating with the receiving cavity; the drive motor, the fan wheel assembly, and the bearing component are all disposed in the receiving cavity; the housing has a bottom surface and a side surface adjacent to the bottom surface, the first air outlet and the second air outlet are located on the side surface, the air inlet is located on the bottom surface, and the axial direction of the bearing component is perpendicular to the bottom surface; the fan wheel assembly is installed in the housing through the bearing component, and the drive motor is drivenly connected to the fan wheel assembly to drive the fan wheel assembly to rotate so as to discharge air through the first air outlet and the second air outlet. The aforementioned car seat fan assembly, through the combination of the housing, drive motor, impeller assembly, and bearing components, boasts a compact size. Its inlet placement design allows for easy installation in suitable locations on the car seat, enabling the impeller assembly to smoothly expel air from the side of the housing through the first and second air outlets. Furthermore, the overall airflow volume and direction are easily controlled. When applied to car seats, it improves ventilation and heat dissipation, enhancing in-vehicle comfort, particularly playing a crucial role in air circulation and temperature regulation in specific areas of the car seat. The following section will further elaborate on this. Figures 1 to 13 The car seat fan assembly, car seat cushion, and car seat are described in detail.

[0054] In some embodiments, a car seat fan assembly 100 is such as Figure 1 As shown, it includes a housing 103, combined with Figure 2 and Figure 3 The car seat fan assembly 100 further includes a drive motor 130, a fan wheel assembly 140, and a bearing 160; the housing 103 has a receiving cavity 104 and a first air outlet 101, a second air outlet 102, and an air inlet 112 respectively communicating with the receiving cavity 104; the drive motor 130, the fan wheel assembly 140, and the bearing 160 are all disposed in the receiving cavity 104; the housing 103 has a bottom surface 105 and a side surface 106 adjacent to the bottom surface 105. The first air outlet 101 and the second air outlet 102 are located on the side 106, the air inlet 112 is located on the bottom surface 105, and the axial direction 200 of the bearing component 160 is perpendicular to the bottom surface 105; the impeller assembly 140 is installed in the housing 103 through the bearing component 160, and the drive motor 130 is drivenly connected to the impeller assembly 140 to drive the impeller assembly 140 to rotate so as to discharge air through the first air outlet 101 and the second air outlet 102. This structural design, through the cooperation of the housing 103, drive motor 130, impeller assembly 140 and bearing 160, has the advantage of small size. Combined with the position design of the air inlet 112, it is easy to place in a suitable position on the car seat, so that the impeller assembly 140 can smoothly exhaust air from the side 106 of the housing 103 through the first air outlet 101 and the second air outlet 102. Moreover, the overall air volume and air direction are easy to control. When applied to car seats, it is beneficial to improve the ventilation and heat dissipation function of car seats, such as car seats, and enhance the comfort of the car. In particular, it can play a key role in the air circulation and temperature regulation of local areas of car seats.

[0055] In each embodiment, such as Figure 2 and Figure 9 As shown, the housing 103 has a receiving cavity 104 and a first air outlet 101, a second air outlet 102, and an air inlet 112 respectively communicating with the receiving cavity 104. The drive motor 130, the impeller assembly 140, and the bearing 160 are all disposed in the receiving cavity 104; in some embodiments, combined with Figure 3The first air outlet 101 and the second air outlet 102 are arranged opposite to each other and have parallel air outlet surfaces, meaning that the air outlet directions of the first air outlet 101 and the second air outlet 102 are opposite. In other embodiments, the air outlet directions of the first air outlet 101 and the second air outlet 102 can also be set at an angle of 60 degrees to 120 degrees, that is, the angle between the air outlet directions of the first air outlet 101 and the second air outlet 102 is 60 degrees to 120 degrees. As an example, the angle between the air outlet directions of the first air outlet 101 and the second air outlet 102 is 80 degrees, 90 degrees, or 100 degrees, etc. This structural design makes it easy to control the overall air volume and air outlet direction when the car seat fan assembly 100 is applied to a car seat, and it can easily realize multi-position air outlet, with air outlets for the buttocks and back being able to be performed simultaneously, thus ensuring the effective delivery of air volume and direction as much as possible. In this way, the two air outlets can be designed in different directions or positions as needed to meet different air supply requirements, such as achieving bidirectional horizontal air supply; or being distributed at a certain angle so as to supply air to spaces at different angles at the same time.

[0056] In some of these embodiments, such as Figure 4 and Figure 5 As shown, the housing 103 includes a connected upper cover 110 and a base 120; the air inlet 112 is located on the upper cover 110, and the first air outlet 101 and the second air outlet 102 are formed between the upper cover 110 and the base 120. In other embodiments, the air inlet 112 may also be located on the base 120; or simultaneously on both the upper cover 110 and the base 120. In other embodiments, the first air outlet 101 and the second air outlet 102 may also be formed on the base 120. Figure 6 and Figure 9 The wind turbine assembly 140 is mounted on the base 120 via the bearing component 160, and together they are connected. Figure 12 and Figure 13 The stator 131 of the drive motor 130 is mounted on the base 120, and the rotor 132 of the drive motor 130 is drivenly connected to the fan assembly 140. This design simplifies the structure of the car seat fan assembly 100, and the car seat fan assembly 100 is easy to assemble. As an example, it can be assembled first into... Figure 11 The internal components shown are wired and assembled onto the base 120, and then the upper cover 110 is connected to the base 120.

[0057] In some of these embodiments, such as Figure 2 and Figure 9As shown, the upper cover 110 is provided with a first connecting member 111, and the base 120 is provided with a second connecting member 122; the first connecting member 111 and the second connecting member 122 are connected to connect the upper cover 110 and the base 120. Figure 7 and Figure 8 In some embodiments, the first connector 111 includes a first snap-fit ​​portion 113 and a first screw-in portion 114, and the second connector 122 includes a second snap-fit ​​portion 128 and a second screw-in portion 129. The first snap-fit ​​portion 113 engages with the second snap-fit ​​portion 128, and the first screw-in portion 114 is screwed into the second screw-in portion 129. This structural design facilitates quick snap-fit ​​alignment of the upper cover 110 and the base 120, followed by screwing to secure them. Furthermore, the design has no protruding sharp parts, making it suitable for use in car seats, such as car seats or car cushions, for protection.

[0058] In some of these embodiments, such as Figure 2 and Figure 7 As shown, the housing 103 or the upper cover 110 of the housing 103 is provided with a reinforcing rib 115 at the position of the air inlet 112. This can protect the air inlet 112, improve the structural strength of the housing 103 or the upper cover 110 at the air inlet 112, and avoid easy damage due to improper load.

[0059] For embodiments with mounting position 121, in conjunction with Figure 4 and Figure 5 In some embodiments, the base 120 is provided with a mounting position 121, the wind turbine assembly 140 is mounted on the mounting position 121 via the bearing 160, and the stator 131 of the drive motor 130 is mounted on the mounting position 121. This allows for quick assembly of the drive motor 130 and the wind turbine assembly 140; in other embodiments, such as Figure 8 and Figure 10 As shown, the positioning mounting base 123 can also be used in conjunction with the mounting position 121 to mount the wind turbine assembly 140 on the positioning mounting base 123 via the bearing component 160, and the stator 131 of the drive motor 130 can be mounted on the positioning mounting base 123; then the positioning mounting base 123 can be mounted on the mounting position 121, thereby realizing the pre-assembly of the semi-finished product and improving the overall assembly efficiency.

[0060] Combination Figure 1 and Figure 8In some embodiments, the housing 103 forms an arc-shaped air guide zone 125 adapted to the impeller assembly 140 on the upper cover 110 and the base 120, and a planar air outlet zone 126 connected to the arc-shaped air guide zone 125, and the planar air outlet zone 126 serves as the first air outlet 101 and the second air outlet 102. The housing 103 protects the internal components and guides airflow through the arc-shaped air guide zone 125, which helps ensure that air can smoothly enter from the air inlet 112 and flow to the two air outlets, making the airflow smoother and reducing energy loss. This design, using an arc-shaped air guide zone 125 in conjunction with a planar air outlet zone 126, is driven by the same motor and delivers air in two directions without crosstalk, resulting in smoother airflow and reduced energy loss. This further maximizes the effective delivery of air volume and direction, allowing the two air outlets to simultaneously deliver air in different directions or areas, significantly increasing the air delivery coverage and enabling more even air distribution in the space. Therefore, the air delivery range is wider. Moreover, compared to traditional blowers with two single air outlets, the automotive seat fan assembly 100 described in this application provides greater air volume and higher air delivery efficiency while occupying the same space, thereby reducing the cost of use and installation difficulty.

[0061] In each embodiment, such as Figure 1 and Figure 2 As shown, the housing 103 has a bottom surface 105 and a side surface 106 adjacent to the bottom surface 105. The first air outlet 101 and the second air outlet 102 are located on the side surface 106, and the air inlet 112 is located on the bottom surface 105. Figure 3 and Figure 6The axial direction 200 of the bearing component 160 is perpendicular to the bottom surface 105. As an example, in the illustrated embodiment, the car seat fan assembly 100 has two bottom surfaces 105 that are parallel or substantially parallel. The surface between the two bottom surfaces 105, adjacent to both bottom surfaces 105, serves as the side surface 106. The first air outlet 101 and the second air outlet 102 are located between the two bottom surfaces 105, and the air inlet 112 is located on one of the bottom surfaces 105, or each bottom surface 105 is provided with the air inlet 112. This structural design makes it easy to place the car seat fan assembly 100 at a suitable position on the car seat, and the overall air volume and direction of the impeller assembly 140 are easy to control, thus facilitating multi-position airflow. Furthermore, the rear and back airflows of the car seat can be performed simultaneously, thus ensuring effective airflow and direction delivery and improving user comfort. Furthermore, the air volume of the two air outlets can be flexibly allocated by adjusting the size, shape, or airflow structure of the air outlets to meet the air supply requirements of different scenarios, depending on different needs.

[0062] In each embodiment, such as Figure 3 As shown, the wind turbine assembly 140 is mounted inside the housing 103 via the bearing 160, and the drive motor 130 is connected to the wind turbine assembly 140 to drive the wind turbine assembly 140 to rotate, so as to discharge air through the first air outlet 101 and the second air outlet 102. In some embodiments, such as Figure 11 and Figure 12 As shown, the drive motor 130 is located within the wind turbine assembly 140. In some embodiments, combined with Figure 6 The bearing component 160 includes a first ball bearing 161 and a second ball bearing 162, which are spaced apart and sleeved on the outside of the wind turbine assembly 140 or on the outside of the shaft core 142 of the wind turbine assembly 140. This design facilitates the installation of the wind turbine assembly 140 in the receiving cavity 104, and through the cooperation of the shaft core 142 with the first ball bearing 161 and the second ball bearing 162, the wind turbine assembly 140 can rotate securely within the housing 103, and also helps to reduce noise.

[0063] In some of these embodiments, such as Figure 3 and Figure 5As shown, the base 120 has a through-hole 127, which can also be understood as the housing 103 having a through-hole 127 on the base 120. In other embodiments, the housing 103 may also have a through-hole 127 on the upper cover 110. This structural design allows for the connection of a power line through the through-hole 127, and the through-hole 127 also serves as an air intake.

[0064] In some of these embodiments, such as Figure 12 and Figure 13 As shown, the housing 103 or the base 120 of the housing 103 is provided with a positioning mounting seat 123; the drive motor 130 is sleeved on the positioning mounting seat 123, and the bearing 160 is disposed in the mounting area 124 of the positioning mounting seat 123, with the outer wall of the bearing 160 abutting against the positioning mounting seat 123; combined with Figure 9 and Figure 10 The impeller assembly 140 includes a wheel-type fan blade 141 and a shaft core 142. The shaft core 142 passes through the bearing member 160 and abuts against the inner wall of the bearing member 160, and a first end of the shaft core 142 is connected to the wheel-type fan blade 141. As an example, the car seat fan assembly 100 also includes a limiting member 170, which connects to a second end of the shaft core 142 away from the wheel-type fan blade 141 to limit the shaft core 142 within the bearing member 160. With this structural design, the wheel-type fan blade 141 rotates under the action of the drive motor 130, the shaft core 142 rotates along the bearing member 160, and the limiting member 170 can maintain the position of the shaft core 142, thus keeping the impeller assembly 140 in position. Furthermore, the drive motor 130 drives the wheel fan blades 141 to rotate, creating airflow. As the wheel fan blades 141 rotate, they exert force on the air, drawing it in from the air inlet 112. After being accelerated by the wheel fan blades 141, the air is then discharged from the two air outlets. The impeller assembly 140 and its drive design are core elements of the automotive seat fan assembly 100, directly affecting its performance. The wheel fan blades 141 typically require high strength and precision to ensure stable air delivery to the two air outlets during high-speed rotation. Thus, one drive motor 130 drives the wheel fan blades 141 to deliver air to the two air outlets, which can be selected according to specific application requirements. This design increases airflow volume and improves air delivery efficiency. Different air delivery effects can be achieved by adjusting the speed and direction of the wheel fan blades 141, and it also helps reduce operating noise, avoiding interference with the quiet riding environment inside the vehicle.

[0065] In some of these embodiments, such as Figure 6 and Figure 13As shown, the wind turbine assembly 140 also includes an elastic element 150 disposed in the mounting area 124, combined with Figure 9 and Figure 10 The shaft core 142 passes through the elastic element 150. In this embodiment, the elastic element 150 is a conical spring. Exemplarily, the outer ring of the conical spring abuts against the positioning mounting seat 123. With this structural design, the wheel blade 141 can be pressed against the bearing 160, such as the first ball bearing 161, by the elastic element 150, especially the conical spring. When the wheel blade 141 and the shaft core 142 rotate, the elastic element 150 can be deformed under pressure, playing an elastic buffering role, which is beneficial to protecting the wheel blade 141 and the shaft core 142, and also beneficial to protecting the positioning mounting seat 123.

[0066] In some embodiments, combined Figures 1 to 13 The car seat fan assembly 100 includes a top cover 110, a base 120, a drive motor 130, a fan wheel assembly 140, an elastic element 150, a bearing element 160, and a limiting element 170. The top cover 110 is injection molded from polybutylene terephthalate (PBT) and primarily prevents the fan wheel assembly 140 from detaching. The fan wheel assembly 140, also injection molded from PBT, is fixed to the bearing element 160 to prevent it from detaching. When the fan wheel assembly 140 operates, it generates airflow and air pressure, achieving a cooling effect. The elastic element 150 is made of piano wire or stainless steel and primarily provides a certain elasticity to the bearing element 160, preventing it from wobbling and generating noise. The drive motor 130 is assembled from several materials, such as silicon steel sheets, enameled wire, and a PCBA board. When energized, the drive motor 130 forms N / S poles to drive the fan wheel assembly 140, causing the fan to operate. Bearing component 160 is made of stainless steel; for example, bearing component 160 may be from brands such as NMB or ISC. Base 120 is injection molded from a copper tube and a PBT ingot, and is used to secure bearing component 160.
