Description

Technical Field

[0001] This invention pertains to vehicle fragrance devices, and specifically relates to a seat fragrance mechanism, system, control method, and vehicle. Background Technology

[0002] With the increasing development of the automotive industry, the items stored in cars are uncertain, and customers' requirements for car odor are getting higher and higher. Car fragrances can greatly improve the smell inside the car. However, car fragrances need to be turned on or off manually by the customer. Because the customer forgets to turn them off after turning them on, the car fragrances are left on for a long time, resulting in waste. Or, because the customer does not turn them on or it is inconvenient to turn them on when sitting in the back seat, the air inside the car cannot be improved.

[0003] Meanwhile, as car controls become increasingly intelligent, simple, and optimized, a seat fragrance system has emerged as a necessity. Summary of the Invention

[0004] To address the above problems, the present invention proposes a seat fragrance mechanism, comprising a seat and a fragrance mechanism, wherein the fragrance mechanism is installed on the outer surface of the seat or inside the seat;

[0005] The fragrance mechanism includes a rocker arm and a fragrance housing. The side surface of the fragrance housing is provided with several ventilation holes. A fragrance box is installed on the bottom surface inside the fragrance housing. A fragrance cover is slidably installed at the opening on the upper surface of the fragrance housing, and a first spring is provided between the fragrance cover and the fragrance box.

[0006] The middle part of the rocker is rotatably connected to the inner surface of the fragrance housing cavity. One end of the rocker is connected to the connecting plate of the fragrance cover, and the other end is slidably installed in the gap between the fragrance box and the fragrance housing, overlapping or separating from the ventilation hole.

[0007] Furthermore, a snap fastener is provided on the outer surface of the fragrance cap that slides in contact with the fragrance housing;

[0008] The inner surface of the fragrance housing is provided with a slot, which is located near the opening; the slot is engaged with a buckle.

[0009] Furthermore, the upper surface of the fragrance cap is provided with a protrusion, and a rubber shock-absorbing pad is provided inside the protrusion, the rubber shock-absorbing pad being in contact with the end face of the first spring.

[0010] Furthermore, the seat includes a seat cushion cover, a seat cushion foam, and a seat frame assembly. The seat cushion foam is installed on the upper surface of the seat frame assembly, and a fragrance mechanism is installed on the upper surface of the seat cushion foam. A fragrance mechanism is installed between the seat frame assembly and the seat cushion foam, and the upper surface of the fragrance mechanism protrudes and contacts the seat cushion foam.

[0011] Furthermore, the seat fragrance mechanism also includes a second spring, one end of which is connected to the end of the rocker plate near the fragrance housing, and the other end is connected to the inner surface of the fragrance housing.

[0012] Furthermore, the seat fragrance mechanism also includes a drive mechanism, which is disposed inside the fragrance box and the drive end of the drive mechanism is fixedly connected to the inner surface of the fragrance cover; or the drive mechanism is disposed outside the fragrance mechanism and is fixedly connected to the outer surface of the fragrance housing or the seat, and the drive end of the drive mechanism is fixedly connected to the outer surface of the fragrance cover.

[0013] A seat fragrance control system includes the aforementioned seat fragrance mechanism, pressure sensing module, detection module, control module, and seat. The seat is equipped with the seat fragrance mechanism, pressure sensing module, detection module, and control module. The pressure sensing module and detection module are electrically connected to the control module, and the control module is electrically connected to the drive mechanism of the seat fragrance mechanism.

[0014] A method for controlling seat fragrance, employing the aforementioned seat fragrance control system, is characterized by further including the following steps:

[0015] The detection module checks whether the vehicle is unlocked;

[0016] If the vehicle is unlocked, the pressure sensor module detects the seat pressure F1;

[0017] If the seat pressure F1 is greater than the set pressure F2, the drive mechanism will drive the seat fragrance mechanism to release fragrance, and the detection module will monitor the vehicle status in real time.

[0018] If a vehicle collision signal or emergency braking signal is detected, the drive mechanism will shut down the seat fragrance system.

[0019] Furthermore, the fragrance concentration c is adjusted based on the seat pressure F1 and the vehicle status;

[0020] The formula for calculating fragrance concentration c is as follows:

[0021] c = d × (1 + a × b), where d is a constant with a value of 0.1-2, the speed coefficient a = 1 - 0.01 × speed v, and the pressure coefficient b = 0.005 × passenger weight m.

[0038] Example 1,

[0039] like Figure 1 As shown, Figure 1 An exploded view of the fragrance mechanism of a seat fragrance device according to an embodiment of the present invention is shown. A seat fragrance device includes a seat and a fragrance device 3, which is installed on the outer surface or inside the seat. The fragrance device 3 includes a rocker arm 34 and a fragrance housing 36. The fragrance housing 36 has a cavity inside and an opening at one end. Several ventilation holes are provided on the side surface of the fragrance housing 36, and both the ventilation holes and the opening communicate with the cavity. A fragrance box 35 is installed in the cavity of the fragrance housing 36, and the fragrance box 35 is fixedly connected to the lower surface of the cavity. A fragrance cover 31 is slidably installed at the opening on the upper surface of the fragrance housing 36, and a first spring 331 is provided between the fragrance cover 31 and the fragrance box 35.

[0040] The elastic element 33 includes a first spring 331 and a second spring 332 (e.g., Figure 3 (As shown); one end of the second spring 332 is connected to the end of the rocker plate 34 near the fragrance housing 36, and the other end is connected to the inner surface of the fragrance housing 36. The second spring 332 generates tension to make the rocker plate 34 coincide with the ventilation hole on the side surface of the fragrance housing 36.

[0041] The middle part of the rocker arm 34 is rotatably connected to the outer surface of the fragrance box 35 and / or the inner surface of the cavity of the fragrance housing 36. One end of the rocker arm 34 is connected to the connecting plate of the fragrance cover 31, and the other end is slidably installed in the gap between the fragrance box 35 and the fragrance housing 36, which coincides with or separates from the ventilation hole.

[0042] Specifically, the fragrance cap 31 and the fragrance housing 36 are connected to the slot 361 via a snap 311; and the vertical movement is achieved through the central concentric cylinder; the fragrance box 35 is a container for storing fragrance, and the fragrance can be refilled and reused by snap-fit ​​disassembly.

[0043] The upper surface of the fragrance cover 31 is provided with a protrusion, and the lower surface of the fragrance cover 31 is provided with a first cylindrical groove. A rubber shock-absorbing pad 32 and a first spring 331 are installed in the first cylindrical groove. A second cylindrical groove is provided in the middle of the fragrance box 35. The first spring 331 is installed in the second cylindrical groove. The second cylindrical groove is slidably installed inside the first cylindrical groove.

[0044] When in use, install the fragrance mechanism 3 onto the upper surface of the seat frame assembly 4 (see reference). Figure 4 Then, a seat cushion foam 2 is installed on the upper surface of the fragrance mechanism 3 and the seat frame assembly 4, and a seat cushion cover 1 is set on the upper surface of the seat cushion foam 2. The above installation scheme realizes that the fragrance mechanism 3 is installed inside the seat, thereby saving installation space. At the same time, it realizes that the fragrance mechanism 3 can be automatically opened when the passenger or driver sits, which is very convenient.

[0045] In the above embodiments, another optional implementation method is that, during use, the fragrance mechanism 3 is installed on the outer side of the seat frame assembly 4, and then a seat cushion foam 2 is installed on the upper surface of the fragrance mechanism 3 and the seat frame assembly 4. A seat cushion cover 1 is set on the upper surface of the seat cushion foam 2. The above installation method realizes that the fragrance mechanism 3 is installed on the outside of the seat, which makes it convenient to replace the fragrance in the fragrance mechanism 3.

[0046] In this invention, a buckle 311 is provided on the outer surface of the fragrance cap 31 that contacts the cavity of the fragrance housing 36.

[0047] Specifically, the elastic arm of buckle 311 has a thickness of 0.5-1.2mm and a buckle angle of 45°±2°; buckle 311 is made of POM (Polyoxymethylene) material with an elastic modulus ≥3GP and local glass fiber reinforcement.

[0048] The inner surface of the fragrance housing 36 is provided with a slot 361, which is located near the opening; the slot 361 is engaged with the buckle 311.

[0049] Specifically, the elastic arm of the buckle 311 deforms along the inner surface of the fragrance housing 36 during insertion. When the buckle 311 passes through the slot 361, an audible clicking sound is produced. According to the JB / T12175 standard test, the life of a conventional buckle is only 500 times, while this application reaches 2000 times.

[0050] When the fragrance box 35 needs to be replaced, the clip 311 of the fragrance cover 31 is removed from the slot 361, and then the fragrance box 35 is removed from the cavity of the fragrance housing 36. The next step is to reinstall the new fragrance box 35 or the fragrance box 35 refilled with fragrance into the cavity of the fragrance housing 36, and install the first spring 331 into the second cylindrical slot of the fragrance box 35. Then, the fragrance cover 31 is connected to the rocker arm 34, and the fragrance cover 31 is installed into the opening of the fragrance housing 36 until the clip 311 is engaged in the slot 361.

[0051] refer to Figure 2 The upper surface of the fragrance cover 31 is provided with a protrusion, and a rubber shock-absorbing pad 32 is provided inside the protrusion. The rubber shock-absorbing pad 32 is in contact with one end of the first spring 331. Specifically, the rubber shock-absorbing pad 32 is embedded in the inner surface of the fragrance cover 31 and the inner surface of the fragrance box 35, and plays a role in vibration reduction.

[0052] The seat fragrance mechanism also includes a drive mechanism 5, which is located inside the fragrance box 35 and the drive end of the drive mechanism 5 is fixedly connected to the inner surface of the fragrance cover 31; or the drive mechanism 5 is located outside the fragrance mechanism 3, and the drive mechanism 5 is fixedly connected to the outer surface of the fragrance housing 36 or the seat, and the drive end of the drive mechanism 5 is fixedly connected to the outside of the fragrance cover 31.

[0053] Specifically, the drive mechanism 5 includes an electric cylinder. The drive mechanism 5 is located inside the fragrance box 35, and the piston rod end of the drive mechanism 5 is connected to the rubber shock-absorbing pad 32; alternatively, the drive mechanism 5 is located outside the fragrance mechanism 3, and is fixedly connected to the outside of the fragrance housing 36 or the seat, with the drive end of the drive mechanism 5 fixedly connected to the outside of the fragrance cover 31. The fragrance cover 31 is moved up and down by the extension and retraction of the electric cylinder to open and close the ventilation holes of the fragrance housing 36. The drive mechanism 5 includes a manual emergency switch; in case of electrical failure, the electric cylinder is manually triggered 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 rocker plate 34 near the fragrance housing 36, and the sealing ring is located around the ventilation hole;

[0055] Alternatively, a sealing ring may be provided on the inner surface of the fragrance housing 36. The diameter of the sealing ring is larger than the diameter of the ventilation hole, thereby improving the sealing effect.

[0056] Installation location 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 upper surface of the fragrance mechanism 3 protrudes and contacts the seat cushion foam 2. 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 surface of the fragrance mechanism 3 and the seat frame assembly 4. The seat cushion cover 1 is set on the upper surface of the seat cushion foam 2. The above installation scheme realizes that the fragrance mechanism 3 is installed inside the seat, thereby saving installation space. At the same time, it realizes that the fragrance mechanism 3 is automatically opened when the passenger or driver sits, which is very convenient.

[0057] In the above embodiments, another optional implementation method is that, during use, the fragrance mechanism 3 is installed on the outer side of the seat frame assembly 4, and then a seat cushion foam 2 is installed on the upper surface of the fragrance mechanism 3 and the seat frame assembly 4. A seat cushion cover 1 is set on the upper surface of the seat cushion foam 2. The above installation method realizes that the fragrance mechanism 3 is installed on the outside of the seat, which makes it convenient to replace the fragrance in 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, which is transmitted to the fragrance mechanism 3. The fragrance mechanism 3 first experiences force on the fragrance cover 31, which compresses the first spring 331. At the same time, the fragrance cover 31 moves downward, and the fragrance cover 31 applies force to the rocker plate 34. The rocker plate 34 is rotatably connected to the fragrance housing 36 through the middle position (the rocker plate 34 is equivalent to a lever, and the rotatable connection between the rocker plate 34 and the fragrance housing 36 is equivalent to a fulcrum). The end of the rocker plate 34 near the bottom surface of the fragrance housing 36 moves upward. At the same time, after the rocker plate 34 moves upward, the ventilation hole of the fragrance housing 36 is exposed, so that the fragrance gas overflows from the fragrance housing 36, thereby improving the air environment.

[0059] When a passenger gets up and leaves the seat, the seat cover 1 is not subject to gravity. At this time, the fragrance mechanism 3 moves upward under the upward force of the first spring 331, the fragrance cover 31 moves upward, and the end of the rocker 34 near the bottom of the fragrance housing 36 moves downward. The end of the rocker 34 near the bottom of the fragrance housing 36 closes the ventilation hole on the fragrance housing 36, thereby realizing that when the person leaves the seat, the fragrance mechanism 3 automatically closes.

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

[0061] Example 2,

[0062] refer to Figure 5 A seat fragrance control system includes a seat fragrance mechanism, a pressure sensing module, a detection module, a control module, and a seat as described in Embodiment 1. The seat is equipped with the seat fragrance mechanism, the pressure sensing module, the detection module, and the control module. The pressure sensing module and the detection module are both electrically connected to the control module, and the control module is electrically connected to the drive mechanism 5 of the seat fragrance mechanism.

[0063] Example 3,

[0064] The seat fragrance control system using Embodiment 2 above further includes the following steps:

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

[0066] If the vehicle is unlocked, the pressure sensor module detects the seat pressure F1;

[0067] If the seat pressure F1 is greater than the set pressure F2, the drive mechanism 5 drives the seat fragrance mechanism 3 to release fragrance, and the detection module monitors the vehicle status in real time.

[0068] If a vehicle collision signal or emergency braking signal is detected, the drive mechanism 5 will shut down the seat fragrance mechanism 3.

[0069] In the above embodiments, another optional implementation is to set a delay in closing the fragrance after leaving the vehicle, with a delay time of ≤10 minutes. When the inventor needs to start the vehicle's fragrance in advance, it can be done remotely (via an app or key). At this time, the car is started or the vehicle's ventilation system is activated, and the drive mechanism 5 drives the fragrance cover 31, which in turn drives the rocker plate 34 away from the ventilation hole on the fragrance housing 36, thereby releasing the fragrance.

[0070] In this invention, the fragrance release rate is adjusted based on the seat pressure F1 and the vehicle status;

[0071] The formula for calculating fragrance concentration c is as follows:

[0072] Fragrance concentration c = base 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 base value d ranges from 0.1 to 2. In a preferred embodiment, when the passenger's weight m is 70 kg and the vehicle speed v is 80 km / h, the base value d is 0.6, and the fragrance concentration c is 0.642 mg / m.

[0074] Where Δt = t1 - t2, and when Δt ≤ 1, d takes the value of 0.6; where Δt is the travel time, t1 is the current travel time, and t2 is the car start time.

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

[0076] When Δt > 3, d takes the value of 0.2; to avoid olfactory fatigue;

[0077] At the same time, the value of d can be adjusted by a switch. For example, when there are infants, pregnant women or people with allergies in the vehicle, the value of d is a constant 0.2.

[0078] refer to Figure 6 ,

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

[0080] S2, if the vehicle is unlocked, the pressure sensing module detects the seat pressure F1; if the seat pressure F1 is less than or equal to the pressure F2, the detection continues; when the vehicle is unlocked, the fragrance preheating is triggered, and the preheating temperature is 40℃±5℃.

[0081] S3, if the seat pressure F1 is greater than the set pressure F2, the drive 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 emergency braking signal is detected, the drive mechanism 5 drives the fragrance cover 31 to close the fragrance.

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

[0084] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
