Description

Technical Field

[0001] This application relates to the field of automotive seat accessories, and more particularly to a passively ventilated seat cushion for truck seats. Background Technology

[0002] Trucks are essential tools for freight transportation, and truck seats are crucial components for enhancing passenger comfort. When passengers are seated, their buttocks experience poor heat dissipation, which is especially pronounced in summer, leading to discomfort such as heat and dampness, significantly impacting their overall experience.

[0003] In related technologies, breathable seat cushions and fans are typically used to improve seat heat dissipation. The fan is built into the seat, and the air blown by the fan passes through the breathable seat cushion to cool the occupant's buttocks. However, adding a fan requires additional installation space inside the seat, increasing production costs and complexity. At the same time, the airflow exiting from the vents only cools the area of ​​the occupant's buttocks near the vents, limiting the cooling area and reducing the overall cooling effect on the occupant's buttocks. Utility Model Content

[0004] In order to reduce the production cost of the seat cushion and improve its heat dissipation effect, this application provides a passively ventilated seat cushion for truck seats.

[0005] This application provides a passively ventilated seat cushion for truck seats, employing the following technical solution: A passively ventilated seat cushion for truck seats, comprising a base plate, a cushion, and a dust cover; The cushion and the dust cover are located on both sides of the base plate, respectively; The dust cover is provided with a corrugated structure. The deformation of the dust cover generates airflow, which passes through the base plate and the soft pad in sequence. The cushion is provided with multiple exhaust grooves, and the sidewalls of the exhaust grooves are deformed to allow the airflow to flow within the exhaust grooves.

[0006] By employing the above technical solution, vibrations during truck operation cause the dust cover to deform. During the compression and stretching of the dust cover, its internal volume changes, leading to changes in internal air pressure. This causes airflow to form inside the dust cover, which then passes through the floor plate and the cushion, thereby dissipating heat from the buttocks of the passengers.

[0007] Simultaneously, when the truck vibrates, the sidewalls of the exhaust duct deform under the pressure of the passenger's buttocks, causing a change in the volume within the exhaust duct. This change in volume causes the airflow to move along the exhaust duct, guiding it to a wider area and increasing the heat dissipation area of ​​the airflow, thus improving the seat cushion's heat dissipation effect.

[0008] Optionally, the exhaust channel is arranged obliquely on the pad.

[0009] By adopting the above technical solution, when the heat from the occupant's buttocks is conducted to the cushion, the exhaust groove is obliquely arranged on the cushion, which increases the path length of the airflow, thereby increasing the heat exchange time between the airflow and the cushion, and thus improving the heat dissipation effect of the seat cushion.

[0010] Optionally, the exhaust groove has a wavy structure.

[0011] By adopting the above technical solution, the exhaust groove is set into a wave-shaped structure, which further increases the path length of the airflow, thereby increasing the heat exchange time between the airflow and the cushion, and further improving the heat dissipation effect of the seat cushion.

[0012] Optionally, the cushion is provided with a plurality of vent holes, which are located within the vent groove; the dust cover allows airflow to pass through the vent holes and enter the vent groove.

[0013] By adopting the above technical solution, the exhaust port is located inside the exhaust groove, which provides space for the airflow and reduces the possibility that the passenger's buttocks will block the outlet of the exhaust port, causing the airflow to be unable to flow.

[0014] Optionally, a support pad may also be included, through which the airflow passes after passing the cushion.

[0015] By adopting the above technical solution, the support pad can provide cushioning between the buttocks of the passenger and the soft pad, reducing the possibility of direct contact between the passenger's buttocks and the soft pad, which could lead to damage to the venting channel.

[0016] Optionally, the support pad has a mesh structure.

[0017] By adopting the above technical solution, the mesh structure of the support pad can distribute the pressure on the occupant's buttocks, improving occupant comfort. Simultaneously, the mesh structure of the support pad improves the breathability of the seat cushion, further increasing the space for airflow.

[0018] Optionally, it also includes an outer skin that covers the base plate, the cushion, and the support pad, through which the airflow passes.

[0019] By adopting the above technical solution, the outer skin covers the bottom plate, the soft pad and the support pad, reducing the possibility that the bottom plate, the soft pad and the support pad will fall off during truck driving.

[0020] Optionally, the cushion is provided with cushion side panels on both sides.

[0021] By adopting the above technical solution, the soft padding sidewalls provide lateral support for passengers, improving their stability during the ride and thus enhancing their comfort.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. Vibrations during truck operation cause the dust cover to deform. During the compression and stretching of the dust cover, its internal volume changes, leading to changes in internal air pressure. This creates airflow within the dust cover, which then passes through the floor and cushioning to dissipate heat from the passengers' buttocks. Simultaneously, the truck's vibrations cause the sidewalls of the exhaust channels to deform under the pressure of the passengers' buttocks, changing the volume within the exhaust channels. This change in volume causes airflow to move along the exhaust channels, guiding it over a larger area and increasing the heat dissipation surface area, thus improving the seat cushion's cooling effect. 2. By arranging the exhaust channels at an angle, the heat from the occupant's buttocks is conducted to the cushion, increasing the path length of the airflow and thus increasing the heat exchange time between the airflow and the cushion, thereby improving the heat dissipation effect of the seat cushion.

[0023] 3. By setting up a support pad, the support pad can provide cushioning between the passenger's buttocks and the soft pad, reducing the possibility of direct contact between the passenger's buttocks and the soft pad, which could damage the air vent. Attached Figure Description

[0026] The following is in conjunction with the appendix Figure 1 -Appendix Figure 3 This application will be described in further detail.

[0027] This application discloses a passively ventilated seat cushion for truck seats. For example... Figure 1 and Figure 2 The passive ventilated seat cushion includes a base plate 1, a soft pad 2, a dust cover 3, a support pad 4, and an outer skin 5. The dust cover 3, base plate 1, soft pad 2, and support pad 4 are installed sequentially from bottom to top.

[0028] like Figure 1 and Figure 2 As shown, the truck seat includes a base plate frame 6 and a base frame 7. In related technologies, in order to improve the shock absorption effect of the truck seat, a shock absorption device is installed between the base plate frame 6 and the base frame 7, so that when the truck vibrates during driving, the base plate frame 6 can move in the vertical direction relative to the base frame 7, thereby achieving the effect of shock absorption and buffering.

[0029] like Figure 1 and Figure 2 As shown, in this embodiment, the base plate 1 is fixedly connected to the base plate frame 6, one end of the dust cover 3 is fixedly connected to the base plate frame 6, and the other end is fixedly connected to the base frame 7. The dust cover 3 has a corrugated structure, which allows the dust cover 3 to deform when the base plate frame 6 moves vertically. After the base plate 1, the soft pad 2, and the support pad 4 are placed sequentially from bottom to top, the outer skin 5 covers the base plate 1, the soft pad 2, and the support pad 4 and is fixedly connected to the base plate frame 6, so that the base plate 1, the soft pad 2, and the support pad 4 can move vertically together with the base plate frame 6. The covering of the outer skin 5 reduces the possibility of the base plate 1, the soft pad 2, and the support pad 4 falling off during truck travel.

[0030] Specifically, when the base frame 6 moves upward, the dust cover 3 stretches; when the base frame 6 moves downward, the dust cover 3 compresses. Multiple ventilation holes are provided on the base frame 7. During the compression and stretching of the dust cover 3, the internal volume changes, resulting in a change in internal air pressure. This allows air to enter from the end where the dust cover 3 connects to the base frame 7, forming an airflow inside the dust cover 3. The airflow passes sequentially through the base plate 1, the soft pad 2, the support pad 4, and the outer skin 5, thus dissipating heat from the buttocks of the passengers. This application utilizes the vibration generated during truck movement, combined with the deformation of the dust cover 3, to generate airflow, thereby achieving heat dissipation for the buttocks of passengers. Compared to related technologies that add a fan for cooling, this application reduces production costs.

[0031] like Figure 3As shown, the cushion 2 has multiple exhaust channels 21 arranged obliquely on the cushion 2, and the exhaust channels 21 are wavy. In this embodiment, the multiple exhaust channels 21 are arranged symmetrically. Multiple exhaust holes 22 are opened in the exhaust channels 21. In this embodiment, the cushion 2 is made of flexible material. During truck operation, the truck vibration causes the sidewalls of the exhaust channels 21 to deform under the pressure of the passenger's buttocks, thus changing the volume within the exhaust channels 21. When the volume within the exhaust channels 21 changes, airflow flows within the exhaust channels 21, thereby guiding the airflow to a larger area, increasing the heat dissipation area of ​​the airflow, and improving the heat dissipation effect of the seat cushion. The oblique and wavy arrangement of the exhaust channels 21 increases the path length of the airflow. When the heat from the passenger's buttocks is transferred to the cushion 2, the increased path length of the airflow increases the heat exchange time between the airflow and the cushion 2, thereby further improving the heat exchange effect of the seat cushion. In addition, the exhaust port 22 is located inside the exhaust groove 21, which provides space for airflow and reduces the possibility that the passenger's buttocks may block the outlet of the exhaust port 22, causing airflow to be blocked.

[0032] like Figure 2 As shown, the airflow passes through the cushion 2 and then through the support pad 4, which has a mesh structure. In this embodiment, the support pad 4 is made of a flexible material. The support pad 4 provides cushioning between the occupant's buttocks and the cushion 2, reducing the possibility of direct contact between the occupant's buttocks and the cushion 2, thus preventing damage to the exhaust channel 21. The mesh structure of the support pad 4 disperses pressure on the occupant's buttocks, improving occupant comfort. Simultaneously, the mesh structure of the support pad 4 improves the breathability of the seat cushion, further increasing the space for airflow and enhancing heat dissipation.

[0033] like Figure 2 and Figure 3 As shown, soft pad sidewalls 23 are provided on both sides of the soft pad 2, and support pad sidewalls 41 are provided on the support pad 4 at the position corresponding to the soft pad sidewalls 23. The soft pad sidewalls 23 and support pad sidewalls 41 provide lateral support for passengers, improve the stability of passengers during the riding process, and thus improve the comfort of passengers during the riding process.

[0034] The implementation principle of a passively ventilated seat cushion for truck seats in this application embodiment is as follows: When vibrations occur during truck movement, the dust cover 3 is compressed and stretched as the floor frame 6 moves. During the compression and stretching of the dust cover 3, airflow is generated inside the dust cover 3. The airflow passes through the floor 1, the cushion 2, the support pad 4, and the outer skin 5 in sequence to dissipate heat from the buttocks of the passengers.

[0035] Meanwhile, during the truck's vibration, the sidewall of the exhaust duct 21 is subjected to pressure from the passengers. As the sidewall of the exhaust duct 21 deforms, the airflow moves within the exhaust duct 21, thereby expanding the airflow area within the seat cushion and increasing the heat exchange area between the airflow and the passenger's buttocks, thus improving the seat cushion's heat dissipation effect.

[0036] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
