Description

Technical Field

[0001] This disclosure generally relates to the technical field of vehicle seats, and in particular, to a vehicle seat with a seat air conditioning system. Background Technology

[0002] With the continuous development of the automotive industry, people have put forward higher requirements for the comfort of vehicle seats, hoping that vehicle seats can provide good heating and cooling functions.

[0003] In existing technologies, heating elements, such as resistance wires, are typically installed within the seat to heat it. These heating elements are complex in structure and manufacturing, resulting in high costs. Seat heating is achieved by consuming additional electrical energy from the entire vehicle. The heating temperature is not adjustable, the heating speed is slow, and heat dissipation is slow after heating, preventing users from precisely controlling the temperature. Heating with resistance wires is prone to causing fires and can lead to seat and foam aging (foam powdering). Heating elements cannot usually be placed in the bending areas of the seat, limiting the heating area and leaving certain parts of the seat unheated, among other issues.

[0004] In existing technologies, fans are typically installed inside the seats to ventilate and cool them. These fans blow or draw air, causing it to circulate through the seats and achieve a cooling effect, rather than directly providing cooling. However, cooling seats with fans has several drawbacks. For example, users cannot adjust the fan speed or precisely control the temperature drop, resulting in ineffective cooling; the fans generate ambient noise inside the vehicle; when the interior temperature is high, the fans draw hot air through the seats, failing to cool them; and since the fans circulate existing air, they cannot eliminate odors and harmful gases like formaldehyde. Furthermore, installing fans inside the seats complicates the seat's structure and manufacturing process, increasing costs.

[0005] Therefore, there is a need to improve existing vehicle seats. Utility Model Content

[0006] One of the purposes of this disclosure is to overcome one or more problems existing in the prior art and to achieve additional advantages.

[0038] This disclosure relates to a vehicle seat in which a seat air conditioning system is integrated into a vehicle seat body comprising a seat cushion body and a seat back body. The seat air conditioning system according to this disclosure eliminates the need for a fan and / or heating device installed in the vehicle seat, reducing the number of parts to be assembled into the vehicle seat, lowering installation difficulty and cost, reducing seat weight, reducing power consumption, eliminating fan noise during temperature adjustment, slowing down the aging of the seat structure, and so on.

[0039] Reference Figure 1 The illustration schematically depicts a vehicle seat 1 according to an embodiment of the present disclosure. The vehicle seat 1 includes at least a seat cushion body 11, a backrest body 12, and a seat air conditioning system 13. The seat cushion body 11 and the backrest body 12 constitute the vehicle seat body, and the seat air conditioning system 13 is coupled to the vehicle seat.

[0040] like Figures 2a to 3b As shown, the seat air conditioning system 13 includes at least an air duct system 131, an air inlet cavity 132, an interface component 133, and an external air conditioning duct 134.

[0041] The air duct system 131 and the air inlet chamber 132 can be installed in the vehicle seat 1 and connected to each other.

[0042] The air duct system 131 and the air inlet cavity 132 can be disposed in at least one of the seat cushion body 11 and the backrest body 12. The following description takes the case where the air duct system 131 and the air inlet cavity 132 are disposed in the seat cushion body 11 as an example. The disposal in the backrest body 12 is similar.

[0043] The air duct system 131 may include an airflow outlet 1311 disposed on the outer surface of the vehicle seat and at least one airflow passage 1312 disposed within the vehicle seat and communicating with the airflow outlet. According to another embodiment of the present disclosure, multiple airflow passages may be provided within the vehicle seat.

[0044] According to one embodiment of this disclosure, the airflow outlets 1311 of the air duct system 131 may be a series of holes distributed in the outer surface of the seat cushion body 11. According to one embodiment of this disclosure, the airflow outlets of the air duct system 131 are uniformly distributed in the outer surface of the seat cushion body 11. In another embodiment of this disclosure, the airflow outlets of the air duct system 131 are non-uniformly distributed in the seat cushion body, for example, distributed in an "O", "E", or "H" shape in the outer surface of the seat cushion body 11.

[0045] The airflow passages of the air duct system 131 can be arranged according to the distribution of the airflow outlets 1311 so that the airflow passages can connect all the airflow outlets 1311. According to one embodiment of this disclosure, when the airflow outlets are distributed in an "O", "E", or "H" shape on the upper surface of the seat cushion body 11, the airflow passages are formed in the seat cushion body in the corresponding "O", "E", or "H" shape. This allows the seat air conditioning system to meet the configuration requirements of different vehicle seats.

[0046] According to one embodiment of this disclosure, the airflow passage 1312 of the air duct system 131 may have a non-constant cross-sectional area. The cross-sectional area of ​​the airflow passage is larger near the air inlet cavity 132, and gradually decreases near the air outlet 1311 depending on the number, size, and layout of the air outlets 1311, so that the airflow from the seat air conditioner felt by the passenger is uniform and gentle.

[0047] The air intake cavity 132 is a cavity that receives the air conditioning airflow entering the vehicle seat and guides the air conditioning airflow into the airflow passage 1312. The air intake cavity 132 may include an air intake cavity body 1321 and an air intake cavity end for connecting the interface member 133.

[0048] According to one embodiment of this disclosure, particularly as Figure 3a and Figure 3b As can be seen, the air intake cavity body 1321 can be configured to be disposed within the vehicle seat near the outer surface having the airflow outlet 1311. According to one embodiment of this disclosure, the air intake cavity body 1321 can particularly be disposed in the portion between the internal support structures of the vehicle seat. According to another embodiment of this disclosure, the air intake cavity body 1321 is disposed in a "C" or "E" shape within the seat cushion body near the outer surface. The air intake cavity body according to this disclosure allows for a larger air intake cavity volume without affecting the stability and comfort of the vehicle seat structure; it can shorten the airflow passage, reducing the risk of the airflow passage being compressed and deformed during long-term use; it can reduce the resistance and temperature loss of the air conditioning airflow during its flow to the airflow outlet; and by being disposed in the portion between the internal support structures of the seat, the air intake cavity does not increase the thickness of the vehicle seat.

[0049] The interface 133 can be configured to connect the air intake cavity 132 and the seat external air conditioning duct 134. A first end of the interface 133 can be sealed to the air intake cavity end of the air intake cavity 132. A second end of the interface 133 can be in fluid communication with the seat external air conditioning duct 134 (e.g., the first end of the seat external air conditioning duct 134).

[0050] According to one embodiment of this disclosure, the first end of the interface member 133 can be configured to achieve a sealed connection with the air inlet cavity end via a slot-pin type connector. According to another embodiment of this disclosure, for an air inlet cavity end with a circular profile, the first end of the interface member 133 can be configured to achieve a sealed connection with the air inlet cavity end via a threaded connector. According to another embodiment of this disclosure, for an air inlet cavity end with a square profile, the first end of the interface member 133 can be configured to have a corresponding square shape, for example, by being tightly fitted inside the air inlet cavity end to achieve a sealed connection, or by being sleeved outside the air inlet cavity end and fitted with a snap-fit ​​element to achieve a sealed connection. In some embodiments, a sealing element can be provided between the first end of the interface member 133 and the air inlet cavity end to enhance the sealed connection between them.

[0051] The second end of the interface member 133 can be threaded to the seat external air conditioning duct 134 (e.g., the first end of the seat external air conditioning duct 134). According to other embodiments of this disclosure, the second end of the interface member 133 can be fixedly connected to or integrally formed with the first end of the seat external air conditioning duct 134. This can provide optimal sealing between the interface member and the seat air conditioning duct.

[0052] The second end of the external air conditioning duct 134 (i.e., the end opposite to the first end of the external air conditioning duct 134) can be connected to the vehicle air conditioning system 2, so that the airflow output by the vehicle air conditioning system enters the vehicle seat through the external air conditioning duct 134, the interface 133, and the air inlet 132, and is finally output from the airflow outlet 1311.

[0053] The external air conditioning duct 134 has a flexible configuration, which allows the external air conditioning duct 134 to adapt to the movement of the vehicle seat by changing its length or shape when the vehicle seat changes position, such as moving forward, backward, left, right, or rotating. This eliminates the need to reinstall or manually adjust the external air conditioning duct 134.

[0054] According to one embodiment of this disclosure, the external air conditioning duct 134 is a flexible tube, which can deform to follow the movement of the vehicle seat. According to another embodiment of this disclosure, the external air conditioning duct 134 is a corrugated tube, which can change its length by stretching or compressing. In other embodiments of this disclosure, the external air conditioning duct 134 can also be a duct composed of several sections of tubular parts that are movable relative to each other, and has the ability to deform within a certain range.

[0055] like Figures 1 to 3bAs shown, the second end of the external air conditioning duct 134 can be directly connected to the air supply duct 21 of the vehicle air conditioning system 2 located under the vehicle seat 1. The air supply duct 21 is typically arranged to pass through the side or under the seat, for distributing hot or cold air generated by the vehicle air conditioning system 2 within the vehicle interior space. In one embodiment according to this disclosure, the external air conditioning duct 134 can be screwed onto a threaded connector provided on the air supply duct 21 via a threaded connector to achieve fluid communication with the air supply duct 21. In another embodiment according to this disclosure, the external air conditioning duct 134 can be connected to a corresponding female or male connector provided on the air supply duct 21 via a spring-clamp type male or female connector to achieve fluid communication with the air supply duct 21.

[0056] The external air conditioning duct 134 of the seat can be equipped with a damper switch to regulate the flow rate of fluid passing through the external air conditioning duct 134. In some embodiments, the user can operate the air conditioning control panel or control knob to control the opening, closing, and opening size of the damper switch, thereby achieving precise temperature regulation.

[0057] For example, when the vehicle's air conditioning system 2 is operating in heating mode, as hot air passes through the air duct 21 under the vehicle seat, the user can operate the vent switch to open the vent, allowing the hot air to enter the external air conditioning duct 134 and then enter the vehicle seat through the air intake chamber 132, thus heating the vehicle seat. The user can also adjust the vent opening to obtain the desired temperature. When the vehicle's air conditioning system is operating in cooling mode, as cooling air passes through the air duct 21 under the vehicle seat, the user can choose to allow the cooling air to enter the external air conditioning duct 134 and then enter the vehicle seat through the air intake chamber 132, thus cooling the vehicle seat. Similarly, the user can also adjust the vent opening to obtain the desired temperature.

[0058] In some embodiments, the seat air conditioning system 13 may be equipped with a temperature sensor to measure, for example, the real-time temperature of fluid flowing to the vehicle seat 1. The temperature sensor may be located at any one of the external air conditioning duct 134, the air inlet 132, or the airflow passage 1312.

[0059] In other embodiments, the air supply duct 21 may also be configured with a separate duct solely for fluid communication between the vehicle air conditioning system 2 and the seat air conditioning system 13. In one embodiment according to this disclosure, the external seat air conditioning duct 134 is directly connected to the separate duct inside the air supply duct 21. This allows the vehicle seat air conditioning to be turned on independently when the vehicle ambient air conditioning is not turned on.

[0060] refer to Figures 1 to 3bThe vehicle seat 1 may further include seat cushion sides 15 on both sides of the seat cushion body 11 and seat back sides 14 on both sides of the seat back body 12. An air duct system may also be provided within the seat cushion sides 15. According to one embodiment of this disclosure, an airflow channel within the seat cushion body 11 branches off to the left and right sides of the seat cushion sides 15, communicating with airflow outlets distributed on the surface of the seat cushion sides 15. An air duct system may also be provided in a similar manner within the seat back sides 14. According to one embodiment of this disclosure, an airflow channel within the seat back body 12 branches off to the left and right sides of the seat back sides 14, communicating with airflow outlets distributed on the surface of the seat back sides 14.

[0061] Similarly, according to one embodiment of this disclosure, the vehicle seat 1 may further include a headrest body and an air duct system and an air outlet disposed in the headrest body and communicating with an airflow channel within the seat back body 12. According to another embodiment of this disclosure, the vehicle seat 1 may further include a leg body extending below the seat cushion body 11 and an air duct system and an air outlet disposed in the leg body and communicating with an airflow channel within the seat cushion body 11.

[0062] The air duct system can be installed in more areas such as the side of the seat cushion, the side of the seat back, the headrest, and the leg area, allowing users to select and control the opening and closing of different areas of the seat air conditioning, providing personalized seat air conditioning services and optimizing the riding experience.

[0063] Depending on the range of the air duct system, the air intake cavity 132 can also be located in different areas of the vehicle seat. For example, the air intake cavity can be located below or to the side of the seat cushion body 11. The air intake cavity can also be located behind or to the side of the seat back body of the vehicle seat. According to other embodiments of this disclosure, the seat cushion body 11 and the seat back body 12 can each be provided with an air intake cavity, and the air intake cavity can be respectively connected to the vehicle air conditioning system. This optimized air intake cavity arrangement allows for an expansion of the volume within the vehicle seat that can accommodate air conditioning airflow, thus optimizing the efficiency of the seat air conditioning system.

[0064] The vehicle seats equipped with the seat air conditioning system according to this disclosure may be driver's seat, front passenger seat and / or rear seats.

[0065] The vehicle seat disclosed herein has a simple structure and manufacturing process; it allows for rapid seat temperature adjustment; it can provide cooling or heating at any position within the vehicle seat; the air used for cooling or heating comes from fresh outside air, avoiding the introduction of potential odors and harmful gases such as formaldehyde from inside the vehicle. The vehicle seat disclosed herein eliminates the need for fans and / or heating devices installed within the vehicle seat, reducing the number of components to be assembled, lightening the seat weight, lowering energy consumption, eliminating fan noise during temperature adjustment, and slowing down the aging of the seat structure.
