[0033] The heating and cooling seat cushion is applied to electric vehicle seats, bicycle seats, motorcycle seats, sightseeing car seats, golf cart seats and other seats. When applied to electric vehicle seats, the lithium battery of the electric vehicle can be used as a power source, or an independently arranged battery can be used for power supply.

[0034] In practice, an appropriate number of the first hole positions 2 and the second hole positions 3 can be selected according to actual conditions, and this is not limited. During use, the user can turn on the control switch 4 according to their own needs. For example, in summer, the user can turn on the cooling function through the control switch 4, and in winter, the user can turn on the heating function through the control switch 4.

[0035] The TEC semiconductor module 8 is a single unit or multiple units. Multiple units can be selected according to actual needs to improve the cooling function or heating function. There is no restriction on this. In the cooling function, the upper layer of the TEC semiconductor module 8 is the cold surface, and the lower layer of the TEC semiconductor module 8 is the hot surface. The fan 7 drives to generate negative pressure, and the external airflow passes through the air inlet channel 6 and passes through the position of the TEC semiconductor module 8. The upper layer of the TEC semiconductor module 8 is the cold surface. After passing through the cold surface, the external airflow passes through the ventilation channel 9 to the first hole position 2 of the seat cushion end face for cooling. Under the second hole position 3, the cooled external airflow is guided to the TEC semiconductor module 8 under the negative pressure of the fan 7 to participate in the airflow circulation; the lower layer of the TEC semiconductor module 8 is the hot surface. After passing through the hot surface, the external airflow is discharged through the exhaust channel 10 to dissipate heat at the hot surface position, thereby improving the cooling effect.

[0036] When the heating function is used, the upper layer of the TEC semiconductor module 8 becomes the hot surface, and the lower layer becomes the cold surface. The remaining process can refer to the above-mentioned cooling process and will not be described in detail.

[0037] refer to Fig. 9 As shown, the TEC semiconductor module 8 includes a cooling surface 11 and a heat dissipation surface 12 arranged below the cooling surface 11, the cooling surface 11 and the heat dissipation surface 12 are communicated with the fan 7, the cooling surface 11 is communicated with the ventilation channel 9, and the heat dissipation surface 12 is communicated with the exhaust channel 10.

[0038] The cooling surface 11 and the heat dissipation surface 12 of the TEC semiconductor module 8 are arranged in an upper and lower structure, the ventilation channel 9 is connected to the cooling surface 11, and the exhaust channel 10 is connected to the heat dissipation surface 12. The ventilation channel 9 and the exhaust channel 10 are separated. When the cooling function is used, the external airflow is cooled by the cooling surface 11 of the TEC semiconductor module 8 and guided to the first hole position 2 through the ventilation channel 9; the external airflow is cooled by the heat dissipation surface 12 of the TEC semiconductor module 8 and discharged through the exhaust channel 10.

[0039] Reference Figure 5 As shown, the ventilation channel 9 is provided with one or more guide strips 13 , and the guide strips 13 are used to guide cold air or hot air to the first hole position 2 .

[0040] The number of the guide bars 13 is set according to the distribution of the first hole positions 2. The airflow flowing through the cold surface of the TEC semiconductor module 8 is guided to the first hole positions 2 through the guide bars 13, thereby facilitating the cooling of the seat cushion by the refrigerated external airflow.

[0041] Specifically, the second hole position 3 is arranged above the fan 7 , and the fan 7 is provided with an upward opening. The fan 7 is driven to circulate the cold air or hot air from the second hole position 3 to the ventilation passage 9 .

[0042] When the fan 7 is driven, negative pressure is generated. Part of the external airflow enters through the air inlet channel 6, and the other part enters through the second hole 3 above the fan 7. By sucking the airflow from the second hole 3, the cold air or hot air from the second hole 3 can be involved in the circulation, thereby improving the cooling and heating functions.

[0043] like Fig.10 As shown, the utility model further includes a ventilation net 14 for cold air or hot air circulation, and the ventilation net 14 is laid on the first hole position 2 and the second hole position 3. The ventilation net 14 is a hole position evenly distributed on the end surface, which can facilitate hot air or cold air to participate in the circulation, that is, under the action of the ventilation net 14, a part of the cold air or hot air derived from the first hole position 2 enters the fan 7 through the second hole position 3 and participates in the circulation.

[0044] like Fig.11As shown, the utility model includes an air guide member 15 arranged at the air outlet at the right end of the cushion body 1 and an air guide decorative member 16 arranged on the air guide member 15 .

[0045] The control switch 4 includes a composite button and a gear button. The composite button is used to switch between the heating function, the cooling function and the off function. The gear button is used to adjust the heating gear or the cooling gear.

[0046] The control switch 4 can be implemented by independently setting a heating button, a cooling button, a switch button and a gear button. In order to reduce the number of buttons, the heating button, the cooling button and the switch can be compounded, such as being designed to be edited as a switch by a single click, edited as a heating mode by a double click, edited as a cooling mode by a triple click, or a short press for a heating mode, and a long press for a cooling mode. The cooling gear is designed to be a three-gear mode, the first gear is a cooling temperature of 24 degrees and a heating temperature of 45 degrees; the second gear is a cooling temperature of 26 degrees and a heating temperature of 40 degrees; the third gear is a cooling temperature of 28 degrees and a heating temperature of 30 degrees.
