Description

Technical Field

[0001] This utility model belongs to the field of automotive seat technology, specifically, it relates to a ventilated automotive seat cushion. Background Technology

[0002] With the development of the automotive industry and the increasing demands of consumers for driving and riding comfort, the functionality of car seats has become one of the key factors affecting the user experience. In high-temperature environments in summer or during long-distance driving, the contact area between the driver and passengers and the seat is prone to stuffiness due to poor air circulation, and may even cause problems such as sweating and stickiness. This not only reduces driving and riding comfort, but may also affect driving concentration, and may even cause skin discomfort in the long run.

[0003] However, in the current technology, the ventilation function of car seats is mostly an exclusive optional feature of high-end models. If consumers want this function when purchasing a car, they have to pay an additional high option fee, which significantly increases the cost of purchasing a car. Meanwhile, mid-to-low-end models are often not equipped with seat ventilation function. Moreover, after the vehicle leaves the factory, the process of modifying the original car seats to be ventilated is complicated and costly. It may also damage the structural integrity of the original car seats, affecting the safety performance of the seats and the original adjustment functions (such as seat height adjustment, backrest angle adjustment, etc.), making it difficult for most mid-to-low-end car owners to enjoy the comfort experience brought by seat ventilation. While some simple ventilated seat cushions have appeared on the market, most of these products rely solely on breathable fabrics for passive ventilation, resulting in limited effectiveness. Some seat cushions with active ventilation structures suffer from design flaws, such as cluttered ventilation duct layouts, improper fan installation leading to excessive noise, or complex installation and fixing structures that make them prone to shifting during use. These issues may even interfere with the normal use of car seats and the deployment of airbags, failing to meet users' core needs for efficient ventilation, convenient installation, and no impact on original vehicle functions.

[0004] In view of this, this utility model is hereby proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a ventilated car seat cushion, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: A ventilated car seat cushion, comprising: Car seats consist of an inner shell and a base. The inner shell is elastically fitted onto the base, and a seat cushion is installed around the perimeter of the inner shell. The ventilation mechanism includes multiple first synchronous pulleys and a transmission pulley rotatably mounted on a base. A first synchronous belt is fitted onto the multiple first synchronous pulleys and the transmission pulley. An L-shaped connecting plate is fixed to one side of the base. Two second synchronous pulleys are rotatably mounted on the L-shaped connecting plate. A second synchronous belt is fitted onto the two second synchronous pulleys. Fans are installed on both the first and second synchronous pulleys. A driving component is installed inside the inner shell. The driving component is respectively engaged with the transmission pulley and one of the second synchronous pulleys.

[0007] Optionally, a transmission rod is fixed on the transmission wheel, and a first bevel gear is fixed at one end of the transmission rod. The first bevel gear engages with the driving component. A rotating shaft is fixed on one side of one of the second synchronous pulleys, and a second bevel gear is fixed at one end of the rotating shaft. The second bevel gear meshes with the first bevel gear. The driving component includes a gear and a toothed plate. The toothed plate is fixed on one side of the inner wall of the inner shell, and the gear is sleeved on the rotating shaft. The gear meshes with the toothed plate.

[0008] Optionally, two adjustable guide rails are installed on the lower side of the base, and multiple buffer components are fixedly connected between the base and the inner shell.

[0009] Optionally, the inner shell has multiple first air vents and multiple second air vents on one side, and the seat cushion has multiple ventilation holes that cooperate with the multiple first air vents and multiple second air vents; the seat cushion has an air vent groove on one side that cooperates with the second air vents.

[0010] Optionally, a guide limiting groove is provided on one side of the inner wall of the inner shell, and the L-shaped connecting plate is slidably fitted in the guide limiting groove.

[0011] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time: By elastically fitting the inner shell onto the base, the seat cushion can be installed around the inner shell. This allows for the installation of the ventilation system without requiring any destructive modifications to the original structure of the seat's inner shell and base. This reduces the impact on the original seat's safety and adjustment functions that can occur when retrofitting ventilation systems to traditional seats. The included fan, driven by a drive unit, rotates all the fans, providing a comfortable driving environment for the driver on the seat cushion. The drive unit also reduces the need for additional power units and their noise, further improving the driving environment. The L-shaped connecting plate, through the elastic connection between the inner shell and the base, enhances the ventilation stability between the ventilation system and the seat body.

Detailed Implementation

[0016] The present invention will now be described in further detail with reference to the accompanying drawings.

[0017] Please see Figure 1-5 As shown, this embodiment provides a ventilated car seat cushion, including: The car seat 1 includes an inner shell 101 and a base 102. The inner shell 101 is elastically fitted onto the base 102, and a seat cushion 103 is installed on the periphery of the inner shell 101. Ventilation mechanism 2 includes multiple first synchronous pulleys 201 and a transmission pulley 202 rotatably fitted on base 102. A first synchronous belt 203 is fitted on the multiple first synchronous pulleys 201 and the transmission pulley 202. An L-shaped connecting plate 204 is fixed on one side of base 102. Two second synchronous pulleys 205 are rotatably fitted on the L-shaped connecting plate 204. A second synchronous belt 206 is fitted on the two second synchronous pulleys 205. Fans 207 are installed on both the first synchronous pulleys 201 and the second synchronous pulleys 205. A driving component 3 is installed inside the inner shell 101. The driving component 3 is respectively fitted with the transmission pulley 202 and one of the second synchronous pulleys 205.

[0018] When the car is driving on a bumpy road, the inner shell 101 and the seat cushion 103 will shake on the base 102. During the shaking, the drive component 3 will drive the transmission wheel 202 and one of the second synchronous pulleys 205 to rotate. Under the transmission of the first synchronous belt 203 and the second synchronous belt 206, multiple fans 207 can be driven to rotate at the same time, so that the air force generated by the fans can be sent to the seat cushion 103, thereby improving the comfort of the driver sitting on the seat cushion 103.

[0019] By elastically fitting the inner shell 101 onto the base 102, the seat cushion 103 can be installed around the inner shell 101. This allows the ventilation mechanism 2 to be installed without requiring any destructive modifications to the original structure of the original seat inner shell 101 and base 102. This reduces the impact on the safety and adjustment functions of the original seat that may occur when retrofitting ventilation facilities to traditional seats. The fan 207, driven by the drive component 3, rotates all the fans 207, providing a comfortable driving environment for the driver on the seat cushion 103. The drive component 3 also reduces the need for additional power units and their noise, further improving the driving environment. The L-shaped connecting plate 204, through the elastic connection between the inner shell 101 and the base 102, improves the ventilation stability between the ventilation mechanism 2 and the seat body.

[0020] In this embodiment, a transmission rod 208 is fixed on the transmission wheel 202, and a first bevel gear 209 is fixed to one end of the transmission rod 208. The first bevel gear 209 cooperates with the driving component 3. In this embodiment, a rotating shaft 210 is fixed to one side of one of the second synchronous pulleys 205, and a second bevel gear 211 is fixed to one end of the rotating shaft 210. The second bevel gear 211 meshes with the first bevel gear 208. In this embodiment, the driving component 3 includes a gear 301 and a toothed plate 302. The toothed plate 302 is fixed to one side of the inner wall of the inner shell 101, and the gear 301 is sleeved on the rotating shaft 210. The gear 301 meshes with the toothed plate 302. In this embodiment, when the car is driving on a bumpy road, the inner shell 101 shakes relative to the base 102. The toothed plate 302 fixed to the inner wall of the inner shell 101 moves synchronously with the inner shell 101. Since the gear 301 is sleeved on the rotating shaft 210 and meshes with the toothed plate 302, the linear movement of the toothed plate 302 drives the gear 301 to rotate, thereby driving the rotating shaft 210 to rotate. When the rotating shaft 210 rotates, it drives the second synchronous pulley 205 fixed to it to rotate, and drives another second synchronous pulley 205 to rotate synchronously through the second synchronous belt 206. On the other hand, it drives the second bevel gear 2 at the end of the rotating shaft 210 to rotate. 11. Rotation; Because the second bevel gear 211 meshes with the first bevel gear 209, the rotation of the second bevel gear 211 drives the first bevel gear 209 and the transmission rod 208 fixed thereto to rotate, thereby driving the transmission wheel 202 to rotate; the transmission wheel 202 drives multiple first synchronous pulleys 201 to rotate synchronously through the first synchronous belt 203, ultimately realizing that the fans 207 on the first synchronous pulley 201 and the second synchronous pulley 205 operate simultaneously; compared with traditional ventilated seats, it not only reduces the manufacturing cost and energy consumption of the device, but also reduces the noise generated by the traditional device during operation, as well as the situation where modification is easy to damage the original vehicle structure.

[0021] In this embodiment, two adjusting guide rails 104 are installed on the lower side of the base 102, and multiple buffers 105 are fixedly connected between the base 102 and the inner shell 101. By setting the adjusting guide rails 104, the base 102 can be adapted to the original car seat track and achieve front and rear sliding adjustment, so that the ventilated seat cushion does not affect the basic position adjustment function of the original car seat after installation. By setting multiple buffers 105, the elastic deformation can be used to buffer the impact of bumps, improve the riding comfort of the driver and passengers, and the elastic restoring force can make the shaking of the inner shell 101 more stable and controllable, providing a stable power input foundation for the drive component 3, so that the fan 207 can run continuously, reducing the situation of transmission failure or unstable ventilation effect due to violent shaking; at the same time, the elastic connection of the buffers 105 does not need to change the original assembly relationship between the inner shell 101 and the base 102, and will not damage the structural integrity of the original car seat, which meets the safety requirements of aftermarket modification. The driving component 3 in this embodiment can also adopt the driving method of existing technology such as a motor. Without affecting the normal use of this device, it can be selected according to the actual needs of the user, and there is no limitation on it.

[0022] In this embodiment, the inner shell 101 has multiple first air vents 106 and multiple second air vents 107 on one side, and the seat cushion 103 has multiple vents 108, which cooperate with the multiple first air vents 106 and multiple second air vents 107. The seat cushion 103 in this embodiment also has an air vent groove 109 on one side, which cooperates with the second air vents 107. Through the multiple air vent grooves 109, since the fan 207 on the L-shaped connecting plate 204 moves with varying airflow directions, the airflow generated by the fan 207 can be evenly delivered to the seat cushion 103 through the air vent grooves 109, improving the stability and uniformity of airflow delivery in actual use.

[0023] In this embodiment, a guide limiting groove 110 is provided on one side of the inner wall of the inner shell 101, and the L-shaped connecting plate 204 is slidably fitted in the guide limiting groove 110. Through the provided guide limiting groove 110, when the car seat 1 is displaced due to bumps, the L-shaped connecting plate 204 will slide directionally along the trajectory of the guide limiting groove 110, thereby limiting the displacement of the L-shaped connecting plate 204 in the horizontal or vertical direction, and thus improving the stability of components such as the second synchronous wheel 205 and the fan 207 during use.
