Description

Technical Field

[0001] This invention belongs to the field of automotive massage seat technology, specifically relating to an automotive seat with a music-infused massage device. Background Technology

[0002] With the continuous upgrading of the demand for comfort in the automotive consumer market, car massage seats have become one of the core configurations of mid-to-high-end models. In the existing technology, car massage seats mostly rely on air pumps to drive air bags to inflate and deflate, and the massage function is achieved by the pressure generated by the expansion of the air bags. For example, a car massage seat with patent publication number CN222946614U has a technical solution including a backrest, a seat cushion, an air pump and several backrest air bags connected to the air pump. The air pump inflates and deflates the backrest air bags individually, partially or completely to achieve the massage action.

[0003] However, these traditional massage seats have significant drawbacks. On the one hand, their limited functionality is a major issue, offering only massage and failing to address the discomfort of prolonged sitting, especially in summer or high-temperature environments. Even with the car's air conditioning on, the airflow cannot directly reach the back area where the body contacts the seat, leading to sweat buildup and significantly reducing comfort. On the other hand, the airbags have low gas utilization efficiency, with the inflation and deflation process serving only the massage function: the deflated gas is directly discharged into the seat without effective recovery or utilization. Furthermore, after the airbags deflate, they rely on negative pressure suction from an air pump or passive contraction due to body pressure, resulting in low reset efficiency. This not only disrupts the massage rhythm but also prevents the expansion of additional functions through the deflation process.

[0004] In addition, existing massage chairs mostly use mechanical movements at fixed frequencies, lacking a connection with the user's sensory experience. For example, they cannot adjust the massage intensity and frequency in conjunction with the rhythm of music, making it difficult to meet users' needs for a personalized and immersive comfort experience. Summary of the Invention

[0005] The purpose of this invention is to provide a car seat with a music-infused massage device, which enables massage, air cooling, and music-infused massage to work in synergy, thereby improving the comfort and experience of long-distance travel.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a car seat with a music-rhythm massage device, comprising...

[0007] The seat body includes a seat cushion, a backrest connected to the seat cushion, a first backrest disposed on the backrest, and a second backrest disposed on the first backrest.

[0008] An air pump installed on the backrest;

[0009] A blower linkage device includes multiple receiving slots opened on a first cushion, a massage air bag disposed inside any one of the receiving slots, an air inlet pipe and an air outlet pipe communicating with the inside of any one of the massage air bags, with the air inlet pipe and the air outlet pipe being distributed opposite to each other, a fastening plate disposed inside the massage air bag, a fixing cylinder disposed at one end of the fastening plate, a conical guide block disposed at the other end of the fastening plate and inserted into the air outlet pipe, a second spring disposed inside the fixing cylinder, a movable conical block disposed at one end of the second spring and extending to the outside of the fixing cylinder, and a first spring sleeved on the outer wall of the fixing cylinder and connected to the fastening plate and the bottom of the massage air bag respectively.

[0010] The music rhythm module includes a controller and an audio acquisition unit for acquiring music signals. The controller is connected to the audio acquisition unit and an air pump. The controller can adjust the air pump according to the music signal so that the inflation and deflation rhythm of the massage air bag is synchronized with the music rhythm.

[0011] As a preferred technical solution of the present invention, it further includes a first sealing ring disposed at one end of the air outlet pipe, and an elastic block disposed on the conical guide block that can seal with the first sealing ring.

[0012] As a preferred embodiment of the present invention, a second sealing ring is further installed at the bottom of the massage air bag, and the movable cone can be engaged with the second sealing ring.

[0013] As a preferred technical solution of the present invention, the outlet end of the air pipe is provided with multiple notches, and the multiple notches are equally spaced; the inner wall of the fixed cylinder is provided with a sliding groove, and the movable cone is provided with a sliding strip that can be slidably connected with the sliding groove.

[0014] As a preferred technical solution of the present invention, it further includes an airflow distributor installed on the backrest, wherein the air pump is provided with a pipe and the pipe is connected to the air inlet end of the airflow distributor.

[0015] As a preferred embodiment of the present invention, the air intake pipe is connected to the air outlet of the airflow distributor, and the controller is electrically connected to the in-vehicle central control screen.

[0016] As a preferred embodiment of the present invention, it further includes a pressure sensor disposed inside the massage air bag, and the pressure sensor is electrically connected to the controller.

[0017] As a preferred embodiment of the present invention, it further includes symmetrically arranged stabilizing seats, with the seat cushion installed on the inner side of the two stabilizing seats.

[0018] As a preferred technical solution of the present invention, it further includes a first opening on the backrest, a second opening inside the first cushion communicating with the receiving groove, and the second opening communicating with the first opening.

[0019] As a preferred embodiment of the present invention, the air intake pipe passes through the first opening and the second opening, and the seat body also includes a headrest.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] This application achieves real-time linkage between "music signal and massage action" through a music rhythm module: the audio acquisition unit accurately captures the music frequency and amplitude, and the controller converts it into the inflation and deflation rhythm of the massage air bag. At the same time, it supports preset modes such as selection through the central control screen to adapt to different music styles, break through the limitations of fixed massage modes, and provide users with an immersive massage experience.

[0022] The air-blowing linkage device of this application realizes the synergy of "massage and air blowing": when the massage air bag is inflated, the conical guide block seals the air outlet pipe to ensure the massage intensity; when deflated, the air outlet pipe is automatically opened, and the gas in the massage air bag is dispersed into a uniform airflow through the notch, which is accurately blown to the back contact area without the need for an additional independent air blowing component; at the same time, the notch avoids the discomfort caused by a single airflow blowing directly, improves comfort, and achieves a seamless connection between massage and air blowing.

[0033] Example 1: Please refer to Figures 1-9 This is the first embodiment of the present invention, which provides a car seat with a music-rhythmic massage device, including...

[0034] The seat body includes a seat cushion 2, a backrest 3 connected to the seat cushion 2, a first backrest 31 mounted on the backrest 3, and a second backrest 32 mounted on the first backrest 31. From a comfort perspective, the multi-layered backrest structure, through a combination of different materials (such as high-elasticity sponge for the first backrest 31 and skin-friendly memory foam for the second backrest 32), achieves a dual effect of "support + fit." The first backrest 31 provides sufficient support to prevent back pain caused by prolonged use; the second backrest 32 conforms to the curve of the human back, reducing the gap between the back and the backrest and improving contact comfort. From a functional adaptability perspective, the first backrest 31 can be used to create a slot 310 for installing a massage airbag 6, while the second backrest 32 can cover the massage airbag 6, preventing the massage airbag 6 from directly contacting the human body and creating an abrupt feeling. The pressure transmission during the inflation and deflation of the massage airbag 6 is not affected, balancing the massage function and user comfort. It also includes symmetrically arranged stabilizing seats 1, with the seat cushion 2 installed inside the two stabilizing seats 1. The symmetrical stabilizing seats 1 provide bidirectional support for the seat cushion 2, preventing it from shifting or sinking to one side due to long-term human weight bearing, thus extending the lifespan of the seat cushion 2. From a safety perspective, the stabilizing seats 1 limit the lateral displacement of the seat cushion 2, especially during rapid acceleration, braking, or turning, reducing the swaying of the seat cushion 2 and lowering the risk of tilting due to seat instability, thus improving riding safety. The seat also includes a headrest, which supports the user's head. From a safety perspective, in the event of a rear-end collision, the headrest prevents the head from violently tilting backward, reducing the risk of cervical spine injury, and meeting automotive safety design standards.

[0035] An air pump 5 and an airflow distributor 4 are installed on the backrest 3. The air pump 5 is equipped with a pipe 51, which is connected to the air inlet of the airflow distributor 4. The air inlet pipe 41 is connected to the air outlet of the airflow distributor 4. The addition of the airflow distributor 4 enables "centralized distribution and precise delivery" of the gas output from the air pump 5, avoiding the chaotic air path caused by multiple air inlet pipes 41 being directly connected to the air pump 5, and reducing the risk of air pipe entanglement and leakage. From the perspective of pressure balance, the airflow distributor 4 can adjust the gas pressure output to each air inlet pipe 41, ensuring that each massage air bag 6 receives a stable air inlet pressure, avoiding uneven massage intensity due to insufficient pressure in some air bags, and improving the consistency of massage effect. From the perspective of ease of control, this structure can drive multiple massage air bags 6 with a single air pump 5, eliminating the need to configure a separate air pump for each massage air bag 6, reducing equipment cost and energy consumption. It also includes a first opening 33 on the backrest 3, and a second opening inside the first cushion 31 that connects to the receiving groove 310, with the second opening connected to the first opening 33. The air intake pipe 41 passes through the first opening 33 and the second opening. The opening of the first opening 33 and the second opening provides a dedicated passage for the air intake pipe 41, preventing the air intake pipe 41 from being exposed outside the seat or randomly inserted into the gaps in the cushion, reducing the probability of the air intake pipe 41 being squeezed or worn, and extending the service life of the air intake pipe 41. From the perspective of ease of installation, the clear opening position can guide the air intake pipe 41 to accurately connect to the airflow distributor 4 and the massage air bag 6, reducing the difficulty of positioning the air intake pipe 41 during installation and improving assembly efficiency. From the perspective of aesthetics, the hidden air pipe layout can maintain the appearance integrity of the seat backrest 3 and the first cushion 31, and prevent the air intake pipe 41 from being exposed and affecting the overall visual effect of the seat.

[0036] The air-blowing linkage device includes multiple receiving slots 310 formed on the first backrest 31, and a massage airbag 6 fixedly disposed inside any one of the receiving slots 310. The massage airbag 6 consists of two parts: a rigid plate and an airbag body disposed on the rigid plate. This structure can provide stable support through the rigid plate. The flexible nature of the airbag body can conform to the back of the human body, balancing support and comfort.

[0037] The wall of the receiving groove 310 can limit the massage air bag 6, preventing the massage air bag 6 from shifting or flipping laterally during inflation and deflation, ensuring that the massage air bag 6 is always in the corresponding massage area and guaranteeing massage accuracy.

[0038] The air inlet pipe 41 and air outlet pipe 61, which are connected to the inside of any one of the massage air bags 6, are distributed opposite each other to form a two-way channel for "air intake and exhaust". This avoids local stagnation of gas inside the massage air bag 6, ensures uniform inflation and deflation speed, and improves the smoothness of the massage rhythm. From the perspective of functional synergy, the air inlet pipe 41 is responsible for delivering the gas required for massage, and the air outlet pipe 61 is responsible for expelling the gas from the air bag and realizing the blowing function. The relative distribution of the two can direct the exhaust gas directly to the contact area between the human body and the seat, avoid airflow dispersion, and improve the blowing and heat dissipation effect. From the perspective of structural symmetry, the relative distribution of air pipes can balance the structural forces on both sides of the massage air bag 6 and avoid the risk of air bag deformation caused by the connection of air pipes on one side.

[0039] The fastening plate 71 is located inside the massage air bag 6, the fixing cylinder 7 is located at one end of the fastening plate 71, and the conical guide block 710 is located at the other end of the fastening plate 71 and inserted into the air outlet pipe 61.

[0040] A second spring 72 is located inside the fixed cylinder 7, and a movable cone 8 is located at one end of the second spring 72 and extends to the outside of the fixed cylinder 7. A first spring 9 is sleeved on the outer wall of the fixed cylinder 7 and connected to the fastening plate 71 and the rigid plate inside the massage air bag 6. The elastic coefficient of the second spring 72 is greater than that of the first spring 9. In the initial stage of air intake, the air pressure inside the massage air bag 6 pushes the movable cone 8, the fixed cylinder 7, the fastening plate 71, and the conical guide block 710 upward as a whole. At this time, the second spring 72 is not yet compressed. After the conical guide block 710 and the air outlet pipe 61 are sealed, the air pressure of the continued air intake will compress the second spring 72, and the gas will officially enter the air bag. The body expands to create a hammering effect for massage. When air intake stops, the second spring 72, with its large elastic coefficient, first pushes the movable cone 8 downward to engage with the second sealing ring 63, blocking the air intake pipe 41 and preventing gas backflow. Then, the contraction force of the first spring 9 drives the fixed cylinder 7, fastening plate 71, and movable cone 8 to move downward as a whole, further compressing the second sealing ring 63, making the air intake pipe 41 more tightly sealed. At the same time, the downward movement of the fixed cylinder 7, fastening plate 71, and movable cone 8 opens the air outlet pipe 61, thus achieving air path switching. This allows the gas in the air bag to be discharged through the air outlet pipe 61, realizing the blowing operation.

[0041] It should be noted that when the fixed cylinder 7, fastening plate 71, and movable cone block 8 move downward as a whole, they will drive the conical guide block 710 downward as well, so that the air outlet pipe 61 can be opened. However, since the conical guide block 710 is conical, it only needs to move downward a certain distance. The small diameter of the conical guide block 710 corresponds to the inner diameter of the air outlet pipe 61 to form an airflow gap, which can realize the gas discharge. In order to ensure that the fixed cylinder 7, fastening plate 71, and movable cone block 8 can correspond to the air outlet pipe 61 and the air inlet pipe 41 when they move up and down as a whole, the conical guide block 710 remains inside the air outlet pipe 61 when it moves down to open the air outlet pipe 61, and the movable cone block 8 remains inside the air inlet pipe 41 when it moves up to open the air inlet pipe 41, so that the sealing mechanism will not be misaligned due to the air intake and exhaust.

[0042] When the air intake stops, after the second spring 72 drives the movable cone block 8 to complete the sealing of the air intake pipe 41, the auxiliary pull fastening plate 71 moves down as a whole, driving the cone guide block 710 to move down from the air outlet pipe 61, realizing the air outlet pipe 61 is open, and ensuring smooth exhaust blowing action.

[0043] If a second spring 72 is not added inside the fixed cylinder 7, although the movable cone 8 can be moved by the air pressure of the air intake, and the fixed cylinder 7 and the fastening plate 71 can be moved upward to seal the air outlet pipe 61, and the air outlet pipe 61 can be opened by relying on the first spring 9 to reset when the air is released, the effect will be significantly affected. When the air intake stops, the first spring 9 will reset, which will cause the "exhaust-blocking" action to be reversed, resulting in the gas in the air bag flowing back to the air intake pipe 41 and reducing the blowing efficiency.

[0044] A first sealing ring 62 is provided at one end of the air outlet pipe 61, and an elastic block 7101 is provided on the conical guide block 710 to seal with the first sealing ring 62. The elastic block 7101 (preferably made of silicone) has good elastic deformation ability and can fit tightly with the first sealing ring 62 (preferably made of nitrile rubber) when in contact, filling the tiny gap between the two, preventing gas from leaking from the air outlet pipe 61 when the massage air bag 6 is inflated, ensuring stable pressure inside the air bag, and guaranteeing massage intensity. From the perspective of wear adaptability, the elastic properties of the elastic block 7101 can buffer the impact force when the conical guide block 710 contacts the first sealing ring 62, reduce the rigid friction between the two, reduce the wear rate, and extend the service life of the sealing components.

[0045] The second sealing ring 63 is installed at the bottom of the massage air bag 6. The movable cone block 8 can engage with the second sealing ring 63. When inflating, after the conical guide block 710 seals the air outlet pipe 61, the continuous air pressure will push the movable cone block 8 to squeeze the second spring 72 and move upward, ensuring that the air in the air inlet pipe 41 can smoothly enter the massage air bag 6 body. When deflating, the movable cone block 8 first engages with the second sealing ring 63 under the action of the reset force of the second spring 72 to block the air inlet pipe 41 and prevent the air in the air bag from flowing back. Then, the first spring 9 pulls the fastening plate 71 downward to open the air outlet pipe 61 to release the air. The second sealing ring 63 is fixed at the bottom of the air bag and its position is fixed, which makes it easy for the movable cone block 8 to be accurately positioned and engaged, avoiding sealing failure caused by the position displacement of the sealing component.

[0046] The music rhythm module includes a controller 34 and an audio acquisition unit for collecting music signals. The controller 34 is connected to the audio acquisition unit and the air pump 5. The controller 34 can adjust the air pump 5 according to the music signal, so that the inflation and deflation rhythm of the massage airbags 6 is synchronized with the music rhythm, realizing the linkage between "music signal and massage action". This breaks through the fixed frequency massage mode of traditional massage chairs, and makes the inflation and deflation rhythm of the massage airbags 6 synchronize with the music rhythm (such as the airbags inflating rapidly when there are low-frequency heavy sounds and slowly inflating when there are high-frequency light sounds), thus enhancing the immersive massage experience. From the perspective of control precision, the audio acquisition unit can collect the frequency and amplitude signals of the music in real time. The controller 34 converts the signals into the output power of the air pump 5 through an algorithm, ensuring that the synchronization error between the massage rhythm and the music is less than 0.1s, thus improving the rhythm effect. From the perspective of personalization and adaptability, the controller 34 can adjust the control parameters according to different music styles (such as rock, classical, and jazz) to meet the user's needs for different massage rhythms.

[0047] In this embodiment, preferably, the outlet port of the air outlet pipe 61 has multiple notches 610, and the multiple notches 610 are evenly distributed. The evenly distributed notches 610 can disperse the gas discharged from the air outlet pipe 61 into multiple small airflows, avoiding the local wind speed being too high and the body feeling uncomfortable caused by a single airflow blowing directly towards the human body, so that the airflow covers the back skin more evenly and improves the comfort of heat dissipation. The smaller gaps and dispersed distribution of the notches 610 can reduce the probability of large particles of impurities entering the interior of the air outlet pipe 61 and reduce the risk of airway blockage.

[0048] In this embodiment, preferably, the controller 34 is electrically connected to the in-vehicle central control screen. Users can directly control the start / stop and mode switching (such as selecting "emphasis mode" or "soothing mode") of the music rhythm module through the in-vehicle central control screen, without the need for an additional independent control panel, thus reducing operational complexity. From an interactive experience perspective, the central control screen can display the current music rhythm and the working status of the massage airbags 6 (such as pressure value and inflation / deflation frequency), allowing users to intuitively understand the device's operation and improving interactive transparency. From a functional integration perspective, this connection method can realize the linkage between the seat massage function and the in-vehicle entertainment system (such as starting the massage while selecting music through the central control screen), enhancing the overall intelligent experience of the vehicle.

[0049] In this embodiment, preferably, a pressure sensor is also included inside the massage air bag 6, and the pressure sensor is electrically connected to the controller 34. The pressure sensor can detect the pressure value inside the massage air bag 6 in real time. When the pressure exceeds a preset threshold (e.g., 0.3 MPa), the controller 34 will automatically reduce the output power of the air pump 5 to avoid excessive massage intensity caused by excessive pressure in the massage air bag 6, which could cause user discomfort or damage to the massage air bag 6. From the perspective of optimizing the massage effect, the pressure sensor can provide feedback on the actual pressure of the air bag. The controller 34 adjusts the air intake according to the feedback data to ensure that the pressure of each massage air bag 6 is maintained in the optimal massage range (e.g., 0.15-0.25 MPa), ensuring the consistency and comfort of the massage intensity. From the perspective of equipment protection, real-time pressure monitoring can prevent the massage air bag 6 from aging accelerated due to long-term overpressure operation and extend the service life of the air bag.

[0050] Example 2: Please refer to Figures 1-9 This is the second embodiment of the present invention, which is based on the previous embodiment, but differs in that:

[0051] The inner wall of the fixed cylinder 7 is provided with a sliding groove 73, and the movable cone 8 is provided with a slide bar 81 that can slide and connect with the sliding groove 73. The cooperation between the sliding groove 73 and the slide bar 81 can limit the movement trajectory of the movable cone 8, ensuring that the movable cone 8 moves only along the axial direction of the fixed cylinder 7, avoiding rotation or offset of the movable cone 8 during sliding, and ensuring that the movable cone 8 can accurately engage or disengage with the second sealing ring 63. From the perspective of wear uniformity, the sliding guide structure can make the contact area between the movable cone 8 and the fixed cylinder 7 evenly distributed, reducing local excessive wear and extending the service life of the movable cone 8 and the fixed cylinder 7. From the perspective of smooth operation, the cooperation between the sliding groove 73 and the slide bar 81 can reduce the frictional resistance when the movable cone 8 slides, avoid delays in air circuit switching caused by jamming, ensure smoother sealing switching during the "inflation-deflation" process, and improve the synergistic efficiency of massage and blowing functions.

[0052] Working principle and usage process of this invention:

[0053] After entering the vehicle, users can activate the music rhythm massage function of the seats through the in-vehicle central control screen, select preset massage modes (such as "emphasis mode" and "soothing mode"), or directly select target music from the in-vehicle entertainment system associated with the central control screen; after the system starts, the controller 34 automatically initializes, the audio acquisition unit begins to collect the frequency and amplitude signals of the selected music in real time, the pressure sensor enters the working state, and monitors the initial pressure in the massage air bag 6 in real time to ensure that the air pump 5 and the airflow distributor 4 are in standby ready state;

[0054] The controller 34 converts the music signal acquired by the audio acquisition unit into the output power parameters of the air pump 5 through an algorithm. After the air pump 5 starts, it delivers the gas to the airflow distributor 4 through the pipe 51. The airflow distributor 4 adjusts the gas pressure output to each air inlet pipe 41 according to the instructions of the controller 34 to ensure that the air pressure of each air inlet pipe 41 is stable.

[0055] Gas enters the massage air bag 6 through the air inlet pipe 41 (which passes through the first opening 33 of the backrest 3 and the second opening of the first cushion 31). In the initial stage of air intake, the gas pushes the movable cone 8, the fixed cylinder 7, the fastening plate 71, and the conical guide block 710 upward as a whole. At this stage, the second spring 72 is not yet compressed. Until the elastic block 7101 on the conical guide block 710 is tightly fitted with the first sealing ring 62 at one end of the air outlet pipe 61, the air outlet pipe 61 is sealed. When air intake continues, the air pressure inside the massage air bag 6 increases, and the second spring 72 is compressed. The movable cone 8 moves upward, and the gas officially enters the air bag body and expands, pressing against the back of the human body to achieve the massage action.

[0056] During this process, the pressure sensor feeds back the pressure inside the massage air bag 6 to the controller 34 in real time. If the pressure exceeds the preset threshold (e.g., 0.3MPa), the controller 34 automatically reduces the output power of the air pump 5 to reduce the air intake, ensuring that the massage intensity is moderate and avoiding user discomfort or damage to the massage air bag 6.

[0057] When the music signal enters a low-frequency interval or the massage cycle ends, the air pump 5 reduces its output power; the air pressure inside the massage air bag 6 gradually decreases, and the compressed second spring 72 (with an elastic coefficient greater than that of the first spring 9) first releases its energy, pushing the movable cone 8 downward until it precisely engages with the second sealing ring 63, thus sealing the air inlet pipe 41 and preventing the gas inside the air bag from flowing back into the air inlet pipe 41; subsequently, the first spring 9, in a stretched state, releases its potential energy, pulling the fastening plate 71 downward, and the fastening plate 71 drives the fixed cylinder 7, the movable cone 8, and the conical guide block 710 to move downward simultaneously, and the conical guide block 710 moves out of the air outlet pipe 61, thus opening the air outlet pipe 61;

[0058] The remaining gas in the massage air bag 6 is discharged through the air outlet pipe 61 and dispersed into multiple uniform airflows through the equally spaced notches 610 at the air outlet end of the air outlet pipe 61. These airflows are blown towards the area where the human back contacts the seat to dissipate heat and relieve the stuffiness of sitting for a long time.

[0059] After the user turns off the music rhythm massage function via the central control screen, the controller 34 instructs the air pump 5 to stop working, and the remaining gas in the massage air bag 6 is completely discharged through the air outlet pipe 61; the fastening plate 71 and the movable cone block 8 are completely reset under the action of the spring, and the massage air bag 6 returns to its initial state.
