The electric cylinder is extended to drive the fragrance cover 31 to move up and down to complete the opening and closing of the ventilation hole of the fragrance housing 36. The drive mechanism 5 includes a manual emergency switch. When the electric control fails, the electric cylinder is manually triggered to move to open or close the fragrance valve.

[0054] In the above embodiment, another optional implementation is that a sealing ring is provided on the three-dimensional side of the seesaw 34 close to the fragrance housing 36, and the sealing ring is located around the ventilation hole;

[0055] Alternatively, a sealing ring is provided on the inner surface of the fragrance housing 36, and the diameter of the sealing ring is larger than the diameter of the ventilation hole. The sealing effect is improved by providing the sealing ring.

[0056] Installation position of the fragrance mechanism 3: the seat includes a seat cushion cover 1, a seat cushion foam 2 and a seat frame assembly 4, the seat cushion foam 2 is installed on the upper surface of the seat frame assembly 4, and the fragrance mechanism 3 is installed on the upper surface of the seat cushion foam 2; the fragrance mechanism 3 is installed between the seat frame assembly 4 and the seat cushion foam 2, and the bulge on the upper surface of the fragrance mechanism 3 is in contact with the seat cushion foam 2; when in use, the fragrance mechanism 3 is installed on the upper surface of the seat frame assembly 4, and then the seat cushion foam 2 is installed on the upper surfaces of the fragrance mechanism 3 and the seat frame assembly 4, and the seat cushion cover 1 is arranged on the upper surface of the seat cushion foam 2. The above-mentioned installation scheme realizes the installation of the fragrance mechanism 3 inside the seat, thereby saving installation space, and at the same time realizes the automatic opening of the fragrance mechanism 3 by the passengers or the driver sitting, which is very convenient.

[0057] In the above embodiment, another optional implementation is that when in use, the fragrance mechanism 3 is installed on the outer side of the seat frame assembly 4, and then the seat cushion foam 2 is installed on the upper surface of the fragrance mechanism 3 and the seat frame assembly 4, and the seat cushion surface cover 1 is arranged on the upper surface of the seat cushion foam 2. The above installation scheme realizes the installation of the fragrance mechanism 3 to the outside of the seat, which is convenient for replacing the fragrance inside the fragrance mechanism 3.

[0058] Working principle: A seat fragrance control method, when a passenger or driver sits on the seat cushion cover 1, the seat cushion cover 1 is subjected to gravity and transmitted to the fragrance mechanism 3; the fragrance mechanism 3 is first subjected to force on the fragrance cover 31, and the fragrance cover 31 is subjected to force to compress the first spring 331, and at the same time, the fragrance cover 31 moves downward, and the fragrance cover 31 is subjected to force to press the seesaw 34, and the seesaw 34 is rotatably connected to the fragrance shell 36 through the middle position (the seesaw 34 is equivalent to a lever, and the rotation connection between the seesaw 34 and the fragrance shell 36 is equivalent to a fulcrum), and the end of the seesaw 34 close to the bottom surface of the fragrance shell 36 moves upward, and at the same time, after the seesaw 34 moves upward, the ventilation hole of the fragrance shell 36 leaks out, so that the fragrance gas overflows the fragrance shell 36, and the air environment is improved;

[0059] When the passenger stands up and leaves the seat cushion, the seat cushion cover 1 is not subject to gravity. At this time, the fragrance mechanism 3 moves upward due to the upward force of the first spring 331, the fragrance cover 31 moves upward, and the end of the rocker 34 close to the bottom of the fragrance shell 36 moves downward. The end of the rocker 34 close to the bottom of the fragrance shell 36 closes the ventilation holes on the fragrance shell 36, so that the fragrance mechanism 3 is automatically closed when the person leaves the seat.

[0060] In the above embodiment, another optional implementation is that the driving mechanism 5 drives the fragrance cover 31 to move up and down, thereby driving the rocker 34 to block the ventilation holes on the fragrance housing 36 or open the ventilation holes on the fragrance housing 36.

[0061] Embodiment 2,

[0062] refer to Figure 5 A seat fragrance control system comprises the seat fragrance mechanism, pressure sensing module, detection module, control module and seat described in Example 1, wherein the seat fragrance mechanism, pressure sensing module, detection module and control module are installed in the seat, the pressure sensing module and detection module are electrically connected to the control module, and the control module is electrically connected to the driving mechanism 5 of the seat fragrance mechanism.

[0063] Embodiment 3,

[0064] The seat fragrance control system of the second embodiment further includes the following steps:

[0065] The detection module detects whether the vehicle is unlocked;

[0066] If the vehicle is unlocked, the pressure sensing module detects the seat pressure F 1 ;

[0067] If the seat pressure F 1 Greater than the set pressure F 2 , the driving mechanism 5 drives the seat fragrance mechanism 3 to release the fragrance, and the detection module detects the vehicle status in real time;

[0068] If a vehicle collision signal or an emergency brake signal is detected, the driving mechanism 5 drives the seat fragrance mechanism 3 to close.

[0069] In the above embodiment, another optional implementation is that the fragrance can be set to be turned off after leaving the car for a delay of ≤10 minutes. When the inventor needs to start the fragrance of the vehicle in advance, through remote control (app or key), the car is started or the vehicle ventilation system is started, and the driving mechanism 5 drives the fragrance cover 31 to drive the rocker 34 to leave the ventilation hole on the fragrance housing 36, thereby releasing the fragrance.

[0070] In the implementation of the present invention, based on the seat pressure F 1 Adjust the fragrance release rate according to the vehicle status;

[0071] The calculation formula of fragrance concentration c is as follows:

[0072] Fragrance concentration c = basic value d × (1 + vehicle speed coefficient a × pressure coefficient b), where vehicle speed coefficient a = 1-0.01 × vehicle speed v (km / h), and pressure coefficient b = 0.005 × passenger weight m (kg).

[0073] Specifically, the basic numerical value d ranges from 0.1 to 2. In a preferred embodiment, when the passenger weight m is 70 kg and the vehicle speed v is 80 km / h, the basic value d is 0.6. At this time, the fragrance concentration c is 0.642 mg / m.

[0074] Where Δt = t1 -t 2 , when Δt≤1, d is 0.6; where Δt is the travel time, t 1 is the current time of driving, t 2 The time for the car to start.

[0075] When 3≥Δt>1, d takes the value of 0.3; it is gradually reduced to avoid olfactory fatigue;

[0076] When Δt>3, d is set to 0.2 to avoid olfactory fatigue;

[0077] At the same time, the value of d is adjusted by the switch. For example, when there are babies, pregnant women or people with allergies in the car, the value of d is constant at 0.2.

[0078] refer to Figure 6 ,

[0079] S1, the vehicle detection module detects whether the vehicle is unlocked;

[0080] S2, if unlocked, the pressure sensing module detects the seat pressure F 1 ; If the seat pressure F 1 Less than or equal to pressure F 2 , the detection will be repeated; the fragrance preheating is triggered when the vehicle is unlocked, and the preheating temperature is 40℃±5℃.

[0081] S3, if the seat pressure F 1 Greater than the set pressure F 2 , the driving mechanism 5 drives the fragrance cover 31 to release the fragrance, and the detection module detects the vehicle status in real time;

[0082] S4, if a vehicle collision signal or an emergency brake signal is detected, the driving mechanism 5 drives the fragrance cover 31 to close the fragrance.

[0083] The driving mechanism 5 drives the fragrance cover 31 to release the fragrance. Specifically, the driving mechanism 5 drives the fragrance cover 31 to move up and down and then drives the seesaw 34 to block the ventilation holes on the fragrance housing 36 or open the ventilation holes on the fragrance housing 36 .
