Description

Technical Field

[0001] The present invention relates to the field of seat temperature control equipment, in particular to an intelligent seat temperature management mechanism. Background Art

[0002] In existing seat ventilation systems, their core relies on the coordinated operation of a fan, air ducts, and a breathable seat fabric. Although the fan is crucial for generating airflows, centrifugal or axial fans driven by small DC motors often consume high energy during operation. When multiple fans operate simultaneously, the power consumption of the entire ventilation system is huge, which not only increases energy consumption but also affects the endurance and energy utilization efficiency in fields such as automobiles and aerospace that rely on limited energy supplies. In addition, the air ducts are made of plastic or rubber pipes, which are prone to damage due to bending and aging during long-term use, resulting in air leakage, affecting the ventilation effect, and having relatively high maintenance and replacement costs. Moreover, existing ventilation systems can only achieve functions similar to blowing by a fan and cannot truly refrigerate. In hot weather, it is difficult to bring a comfortable cooling experience to the driver and passengers. The reason is that they lack an effective refrigeration mechanism and simply promote air flow without being able to change the air temperature.

[0003] For automotive seat electric heating systems, the heating wire is the core, equipped with a temperature sensor, a control system, and power lines. Although the heating wire can generate heat when powered on, heating wires made of resistance materials such as nickel-chromium alloys have the problem of uneven heating, which easily leads to local overheating or overcooling of the seat and affects the user's physical comfort. At the same time, there is a risk of electric leakage in resistance wire heating. Once the insulation layer is damaged, it may pose a threat to the personal safety of the driver and passengers. Moreover, the seat electric heating and ventilation systems are independent of each other. These two systems not only occupy a large amount of space, increasing the complexity of seat design and installation, but also keep the cost high, with relatively high production and manufacturing costs as well as later maintenance costs. Summary of the Invention

[0017] The present invention will now be described in further detail with reference to the drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so they only show the components related to the present invention.

[0018] Figure 1 This is a schematic structural diagram of the present invention.

[0019] As shown in the Figure 1 accompanying drawings, an intelligent seat temperature management mechanism includes a medium delivery pipe 1, a pump body 2, a temperature sensor 3, a controller 4, and a cooling and heating adjustment mechanism 5. The pump body 2 is connected to the cooling and heating adjustment mechanism 5 through a pipeline, and the cooling and heating adjustment mechanism 5 is connected to the medium delivery pipe 1 through a pipeline. The motor of the pump body 2, the temperature sensor 3, and the cooling and heating adjustment mechanism 5 are all communicatively connected to the controller 4.

[0020] The pump body 2 is responsible for transporting heat or cold during the refrigeration and heating processes. During refrigeration, air or coolant transfers the cold generated by heating the refrigeration chip to the seat surface; during heating, the heat generated by the heating refrigeration chip and the PTC heater is transported out. By adjusting the medium flow rate, the heat exchange efficiency can be controlled to achieve rapid temperature adjustment or stable maintenance.

[0021] The cooling and heating adjustment mechanism 5 includes a heat exchanger 51, a radiator 52, a heating and refrigeration chip, and a PTC heater. The heating and refrigeration chip and the PTC heater are fixed between the heat exchanger 51 and the radiator 52.

[0022] When the heating and refrigeration chip is powered on, one side of the chip cools and the other side heats. By precisely controlling the direction and magnitude of the current, the refrigeration and heating modes can be flexibly switched, and the temperature can be adjusted. It has the advantage of fast response speed and can achieve temperature changes in a short time to meet the user's demand for rapid adjustment of the seat temperature.

[0023] The PTC heater, as an auxiliary heating component, starts when the heating capacity of the heating and refrigeration chip is insufficient or rapid temperature increase is required in the heating mode. The PTC heater has the characteristics of high heating efficiency and good constant temperature performance. As the temperature rises, its resistance increases and the current automatically decreases, thus avoiding overheating and ensuring the safety and stability of the heating process.

[0024] The heat exchanger 51 can achieve heat exchange between air or coolant and the inside of the seat. The heat exchange area and process are optimized to improve the heat exchange efficiency, enabling the seat temperature to quickly respond to system regulation and evenly transfer to all parts of the seat, enhancing user comfort.

[0025] The radiator 52 is used to dissipate the heat generated on the heating surface of the heating and refrigeration chip in the refrigeration mode to ensure the efficient and stable operation of the heating and refrigeration chip. High-efficiency heat dissipation materials and designs, such as large-area heat dissipation fins combined with fan-assisted heat dissipation, are used to quickly dissipate the heat to the surrounding environment.

[0026] The controller 4 receives real-time temperature data from the temperature sensor 3, compares and analyzes the received data with the user-predefined temperature, and then precisely regulates parameters such as the working current of the heating and cooling chip, the startup and shutdown of the PTC heater, and the flow rate of the pump body 2, ensuring that the seat always maintains within the temperature range expected by the user.

[0027] The medium delivery pipe 1 is an air delivery pipe or a liquid delivery pipe, and several air outlet holes are distributed on the pipe body of the air delivery pipe. The gas sent into the air delivery pipe by the air pump will be ejected through the air outlet holes.

[0028] The medium delivery pipe 1 is composed of two L-shaped pipes 11. The two L-shaped pipes 11 are parallel to each other, and the two L-shaped pipes 11 are respectively connected to the left and right sides of the heat exchanger 51 through horizontal straight pipes 12. The medium delivery pipe 1 can ensure the reasonable flow of air or coolant inside the seat, evenly distribute heat and cold to the seat surface, avoid local temperature unevenness, and provide a comfortable and consistent temperature experience for the user.

[0029] The pump body 2 is a liquid pump or an air pump.

[0030] The number of temperature sensors 3 is more than two, and several temperature sensors 3 are distributed on the backrest and seat surface of the seat. The temperature sensors 3 are distributed in areas close to the human contact area such as the seat surface and inside. They can monitor the seat temperature with high precision and in real time, and quickly feedback the temperature signal to the controller 4, providing a data basis for precise temperature regulation.

[0031] Inspired by the ideal embodiments of the present invention described above, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this invention. The technical scope of this invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
