An automotive seat with multiple ventilation functions

Abstract

The present invention relates to the technical field of automotive seats, and discloses an automotive seat with multiple ventilation functions, including a seat mechanism. At the lower center inside the seat mechanism, there is an air interaction mechanism for ventilating the outer surface of the seat. At the lower end of the air interaction mechanism, there is a heating mechanism for heating the air. On both sides of the air interaction mechanism, there are reciprocating flipping mechanisms for driving the air interaction mechanism to reciprocate and tilt and flip. When the outside temperature is relatively high, multiple motors in the air interaction mechanism start to rotate forward, which causes multiple fan blades to rotate and generate an air current, sucking away the heat around the seat surface. At this time, the seat surface remains cool, effectively improving the comfort of sitting. When the temperature drops, the heating mechanism is activated, and the motors rotate in the reverse direction, pushing the fan blades in the air interaction mechanism to rotate. The air current is heated when passing through the heating mechanism, and then the warm air is sent to the seat surface to ensure that warm air is provided to passengers in a cold environment.

Description

Technical Field

[0001] The present invention relates to the technical field of automotive seats, and specifically to an automotive seat with multiple ventilation functions. Background Art

[0002] An automotive ventilation seat is a seat that provides a comfortable ventilation function through an internal fan or air circulation system. Its main function is to help dissipate heat through the seat cushion and backrest parts of the seat, reduce the temperature of the seat surface, and enhance the comfort of driving or riding. Especially in hot weather conditions, ventilation seats are usually equipped with fans, holes, or special fabric materials to achieve a cooling effect by inhaling and discharging air. Opposite to the traditional seat heating function, ventilation seats can effectively reduce the discomfort caused by being moistened by sweat and provide a more refreshing experience.

[0003] Traditional automotive ventilation seats usually achieve air circulation by embedding multiple small fans into the sponge or filling material of the seat cushion. Although this design has a low cost and is easy to implement, it has certain limitations. Since the fans are distributed inside the seat cushion, the ventilation effect is often uneven, resulting in insufficient ventilation or poor air flow in some areas of the seat cushion, unable to effectively provide a full-coverage cooling sensation and unable to obtain sufficient air flow. Over time, the poorly ventilated parts are prone to accumulating sweat or moisture, bringing an uncomfortable experience to passengers and even potentially affecting the durability of the seat. For this reason, we propose an automotive seat with multiple ventilation functions. Summary of the Invention

When the horizontal movement mechanism is activated, it drives two reciprocating flipping mechanisms to move horizontally, thereby causing the air interaction mechanism and the heating mechanism to move horizontally. During the horizontal movement of the two reciprocating flipping mechanisms, they simultaneously drive the air interaction mechanism and the heating mechanism to perform reciprocating tilting and flipping. This action enables the air interaction mechanism to generate relatively uniform airflows at different positions on the seat surface, preventing poor ventilation caused by uneven fan positions. When the external temperature is relatively high, multiple motors within the air interaction mechanism start to rotate forward, causing multiple fan blades to rotate and generate airflows that suck away the heat around the seat surface. At this time, the seat surface remains cool, effectively enhancing the comfort of sitting. When the temperature drops, the heating mechanism is activated, and the motors rotate in the reverse direction, driving the fan blades within the air interaction mechanism to rotate. The airflows are heated when passing through the heating mechanism and then warm air is sent to the seat surface to ensure warmth for passengers in cold environments. In addition, the support component effectively protects the reciprocating flipping mechanism, the air interaction mechanism, and the heating mechanism from external interference, ensuring the stability of these key components. The operation of the horizontal movement mechanism enables all ventilation and heating functions within the seat to work in coordination, guaranteeing the uniformity and comfort of the ventilation effect. This device comprehensively utilizes multiple functions, providing multiple benefits such as temperature regulation, air circulation, and enhanced comfort, effectively improving the usage experience of the seat.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 11 As shown, the present invention provides a technical solution: an automotive seat with multiple ventilation functions, including a seat mechanism 1. At the lower center inside the seat mechanism 1, there is an air interaction mechanism 6 for ventilating the outer surface of the seat. At the lower end of the air interaction mechanism 6, there is a heating mechanism 7 for heating the air. On both sides of the air interaction mechanism 6, there are reciprocating flipping mechanisms 5 for driving the air interaction mechanism 6 to reciprocally tilt and flip. Outside the air interaction mechanism 6, there is a support assembly 3 for protecting the reciprocating flipping mechanism 5, the air interaction mechanism 6, and the heating mechanism 7. At the lower part inside the support assembly 3, there is a horizontal movement mechanism 4 for driving the reciprocating flipping mechanism 5, the air interaction mechanism 6, and the heating mechanism 7 to move horizontally. When the horizontal movement mechanism 4 operates, it will drive the reciprocating flipping mechanism 5 to operate and drive the air interaction mechanism 6 and the heating mechanism 7 to reciprocally tilt and flip. At the lower end of the support assembly 3, there is an installation assembly 2.

[0035] Furthermore, by utilizing the coordinated operation of multiple mechanisms, this device can provide multiple ventilation functions, effectively solving the problems of uneven ventilation and insufficient comfort of traditional seats. When the horizontal movement mechanism 4 is activated, it drives the two reciprocating flipping mechanisms 5 to move horizontally, thereby causing the air interaction mechanism 6 and the heating mechanism 7 to move horizontally. During the horizontal movement of the two reciprocating flipping mechanisms 5, they simultaneously drive the air interaction mechanism 6 and the heating mechanism 7 to perform reciprocating tilting flips. This action enables the air interaction mechanism 6 to generate relatively uniform airflows at different positions on the seat surface, preventing poor ventilation caused by uneven fan positions. When the external temperature is relatively high, the multiple motors within the air interaction mechanism 6 start to rotate forward, causing the multiple fan blades to rotate and generate airflows that suck away the heat around the seat surface. At this time, the seat surface remains cool, effectively enhancing the comfort of sitting. When the temperature drops, the heating mechanism 7 is activated, and the motor rotates in the reverse direction, pushing the fan blades within the air interaction mechanism 6 to rotate. The airflows are heated when passing through the heating mechanism 7 and then warm air is sent to the seat surface to ensure warmth for passengers in cold environments. In addition, the support assembly 3 effectively protects the reciprocating flipping mechanism 5, the air interaction mechanism 6, and the heating mechanism 7 from external interference, ensuring the stability of these key components. The operation of the horizontal movement mechanism 4 enables all the ventilation and heating functions within the seat to work in coordination, ensuring the uniformity and comfort of the ventilation effect. This device comprehensively utilizes multiple functions, providing multiple benefits such as temperature regulation, air circulation, and enhanced comfort, effectively improving the usage experience of the seat.

[0039] Furthermore, the installation component 2 includes a first installation frame 201, which is fixedly connected to the lower end of the base 101, and installation beams 202 are fixedly connected to both sides of its lower end.

[0040] In a preferred technical solution of this embodiment, please refer to Figure 10 As shown, the horizontal movement mechanism 4 includes four positioning rods 401 and a reciprocating lead screw 404.

A displacement plate 406 is fixedly connected to the upper end of the reciprocating slider 405. Transmission wheels 407 are fixedly sleeved on the output end of the servo motor 403 and the end of the reciprocating lead screw 404 close to the lug 303. A transmission belt 408 is sleeved outside the two transmission wheels 407.

[0041] Further, the horizontal movement mechanism 4 is composed of four positioning rods 401 and a reciprocating lead screw 404. The positioning rods 401 are fixedly connected to one side of the protection frame 302. The reciprocating lead screw 404 is sleeved in the lug 303 through a bearing and drives the reciprocating slider 405 to slide within the guide frame 308.

Through the sliding of the reciprocating slider 405, the air interaction mechanism 6 and the heating mechanism 7 of the seat can perform horizontal displacement, thereby realizing the adjustment of the ventilation or heating effects on different parts and improving the seat comfort.

[0042] In a preferred technical solution of this embodiment, please refer to Figure 12 and Figure 13 As shown, the reciprocating flipping mechanism 5 includes a vertical plate 501. The vertical plate 501 is fixedly connected to one side near the upper end of the displacement plate 406.

A sector gear 506 is fixedly connected to the end of the third positioning column 505 away from the docking plate 503. A fixed disk 507 is fixedly connected to the end of the sector gear 506 away from the third positioning column 505.

The rotation of the sector gear 506 and several tooth buckles 509 will alternately mesh with the transmission gear 5010 for transmission, thereby driving the transmission gear 5010 to rotate reciprocally alternately, so as to realize the reciprocating flipping of the air interaction mechanism 6. This design can flexibly adjust the air flow direction to ensure that the air can be evenly distributed on the seat surface, which not only improves the ventilation efficiency but also effectively enhances the comfort of the seat.

[0044] In a preferred technical solution of this embodiment, please refer to Figure 14 As shown, the air interaction mechanism 6 includes a support frame 601.

The upper ends of the fans are connected to the threaded rods 603 through butterfly knobs 605 to ensure the stable operation of the fans. When the reciprocating flipping mechanism 5 drives the air interaction mechanism 6 to flip, the heat dissipation fans 604 operate to generate an air flow, effectively enabling the air to pass through the seat surface. This design, through the cooperation of a plurality of heat dissipation fans 604, ensures that the temperature adjustment on the seat surface is more uniform, providing a more comfortable seat experience.

[0046] In a preferred technical solution of this embodiment, please refer to Figure 15 As shown, the heating mechanism 7 includes a second installation frame 701. The second installation frame 701 is fixedly connected to the lower end of the support frame 601. An electric heating tube 702 is arranged inside the second installation frame 701. A plurality of heat equalizing sheets 703 are fixedly connected in an array outside the electric heating tube 702. The materials of the electric heating tube 702 and the heat equalizing sheets 703 are both pure copper. A temperature sensor is fixedly connected to one side inside the second installation frame 701.

[0047] Further, the heating mechanism 7 includes a second mounting frame 701 and an electric heating tube 702. A heat equalizing sheet 703 is provided outside the heating tube. When the seat needs to be heated, the electric heating tube 702 is heated by passing an electric current. The heat equalizing sheet 703 ensures uniform heating and prevents local overheating. The heating mechanism 7 is located at the lower end of the air interaction mechanism 6 and can combine the heat of the heating tube with air flow to warm the seat surface, providing a comfortable temperature for passengers especially in cold weather. The temperature sensor monitors the temperature of the electric heating tube 702 in real time, thus effectively avoiding the occurrence of overheating.
