TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile seat, especially a car seat massage waist support control valve based on mechanical structure. BACKGROUND

[0002] At present, the automobile seat massage waist support control valve market is mainly occupied by electromagnetic valves and memory metal control valves. As a mature technical solution, electromagnetic valves control the opening and closing of the valve group through electromagnetic effect, realize the switching of the gas circuit, and thus complete the inflation and deflation control of the massage waist support. However, the impact sound between the moving valve core and the fixed valve core of the electromagnetic valve during the working process is difficult to avoid, which not only produces noise, but also seriously affects the comfort experience of the passengers. Especially in the pursuit of high-quality driving environment, this noise problem is particularly prominent.

[0003] On the other hand, the memory metal control valve realizes the switching of the gas circuit by changing the form of memory metal through current, which performs well in noise control, but its product stability is greatly affected by process and material. The processing and material selection of memory metal have high requirements, resulting in high product cost, which limits its wide application in the market.

[0004] Therefore, how to design an automobile seat massage waist support control valve that can effectively control noise, reduce cost, and improve gas circuit switching frequency has become a technical problem to be solved. The present application aims to provide a control valve based on mechanical structure to overcome the shortcomings of the prior art and meet the market demand for high-quality, low-cost, and high-efficiency massage waist support control valve. SUMMARY

[0005] The applicant provides an automobile seat massage waist support control valve based on mechanical structure to overcome the shortcomings of the prior art and meet the market demand for high-quality, low-cost, and high-efficiency massage waist support control valve.

[0006] The technical solution adopted by the utility model is as follows:

[0007] An automobile seat massage waist support control valve based on mechanical structure, comprising:

[0008] The outer shell body comprises a cylindrical hollow inner cavity, and a plurality of groups of gas holes with different heights are arranged on the outer shell body, and each group of gas holes comprises two gas holes in the same plane;

[0009] The valve core is rotatably arranged in the outer shell, and the valve core is hollow and provided with a gas cavity, and an air inlet end is arranged at one end of the gas cavity, a plurality of air inlet holes of different heights are arranged on the valve core and communicated with the gas cavity, and each air inlet hole is arranged on a corresponding plane with each gas hole group, and the rotation of the valve core enables some air inlet holes to be communicated with corresponding gas holes.

[0010] In one embodiment, the control valve further comprises:

[0011] A servo motor is connected to one end of the valve core through a shaft coupling for driving rotation.

[0012] An air nozzle is arranged at the other end of the valve core and connected to the air inlet end of the gas cavity for air supply.

[0013] In one embodiment, bearings are arranged at the upper and lower ends of the valve core and the outer shell, respectively.

[0014] In one embodiment, sealing rings are arranged between the air inlet holes of different heights in the valve core.

[0015] In one embodiment, an exhaust passage is arranged on the corresponding plane of the valve core, the exhaust passage penetrates the valve core and is not communicated with the gas cavity and the air inlet hole, and the distance between the two ends of the exhaust passage and the corresponding plane is the same as the distance between the two gas holes.

[0016] In one embodiment, the two gas holes in the same group are used for air inlet and exhaust, respectively, and the distance between the two gas holes is less than the diameter.

[0017] In one embodiment, the air inlet on the outer shell is used to connect the air charging device.

[0018] In one embodiment, the plurality of air inlet holes are arranged in a spiral shape.

[0019] In one embodiment, the plurality of gas holes are arranged on the same vertical line.

[0020] The beneficial effects of the utility model are as follows:

[0021] The utility model has the advantages of compact and reasonable structure, convenient operation, effective control of noise through rotary motion, reduced product cost and improved market competitiveness through the design of pure mechanical structure, and improved air path switching frequency and enhanced massage effect through the design of servo motor driving valve core rotation. These advantages make the control valve of the embodiment excellent in performance, cost and comfort, and meet the market demand for high-quality, low-cost and efficient massage waist support control valve.

[0022] Meanwhile, the utility model also has the following advantages:

[0023] The control valve of the embodiment controls the massage rhythm through rotary motion, avoiding the impact noise of the moving valve core and the fixed valve core in the traditional electromagnetic valve. The design of the rotary motion structure enables the valve core to smoothly transition when switching the gas circuit, reducing the noise caused by mechanical collision, thereby providing a more peaceful driving environment. This is undoubtedly an important improvement for passengers who pursue high-quality driving experience. Rotary motion not only reduces noise, but also improves the overall comfort of the massage system, so that passengers can enjoy massage without being disturbed by noise.

[0024] The control valve of the embodiment adopts a purely mechanical structure, which greatly reduces the product cost compared to electromagnetic valves and memory metal control valves. Electromagnetic valves require copper winding conductors to generate electromagnetic force, while memory metal control valves have higher requirements for processing and material selection. This scheme realizes the opening and closing function of the valve group through the precise fit of the mechanical valve core and the air inlet, which simplifies the structure and reduces the manufacturing cost. This makes the control valve of the embodiment more advantageous in price, improving the market competitiveness of the product.

[0025] The control valve of the embodiment adopts a servo motor to drive the valve core to rotate, realizing fast and accurate gas circuit switching. Compared with the reciprocating motion of traditional electromagnetic valves, the design of servo motor + mechanical rotary mechanism greatly improves the running speed, thereby improving the response speed of the massage and lumbar support system. This high-speed gas circuit switching capability enables the massage system to adjust the massage intensity and frequency more quickly, better meeting the individual needs of passengers. At the same time, high-frequency gas circuit switching also improves the continuity and comfort of massage, enhancing the driving experience of passengers. BRIEF DESCRIPTION OF DRAWINGS

[0034] The specific implementation of the present application will be described below in conjunction with the drawings.

[0035] As shown in the drawings, the automobile seat massage waist support control valve based on mechanical structure of the present embodiment, including shell 100, valve core 400, servo motor 300 and air nozzle 200, through the rotating way control massage rhythm, avoid the impact noise of traditional control valve in valve core and air inlet, solve the noise problem from the structure itself. Figures 1-5 Specifically, the shell 100 in the present embodiment, including cylindrical hollow cavity, the shell 100 is provided with several groups of different height air hole group 101, and each air hole group 101 includes two air holes 101 in the same plane, two air holes 101 are used for air inlet and air outlet respectively, and multiple air holes 101 are in the same vertical line, which is convenient for processing and assembling.

[0036] The shell 100 as the main structure of the whole control valve, its cylindrical design not only facilitates processing and manufacturing, but also provides sufficient internal space to accommodate the valve core 400 and other components. The air hole group 101 on the shell 100 is the key to realizing different massage functions of the control valve, and each air hole group 101 corresponds to different massage area or intensity. Two air holes 101 are in the same plane, which ensures that when the valve core 400 rotates to a certain position, it can be aligned with the two air holes 101 at the same time, thereby realizing the functions of air inlet and air outlet. This design makes the control valve more compact in structure and easy to operate.

[0037] The valve core 400 in the present embodiment is rotatably arranged in the shell 100, and the valve core 400 is hollow inside and provided with an air cavity 401, and an air inlet end is arranged at one end of the air cavity 401. The valve core 400 is provided with a plurality of air inlet holes 402 of different heights and in communication with the air cavity 401, and each air inlet hole 402 is in the corresponding plane with each air hole group 101, and the rotation of the valve core 400 makes part of the air inlet holes 402 and the corresponding air holes 101 communicate;

[0038] In the present embodiment, the plurality of air inlet holes 402 are distributed in a spiral shape, so that at most one air inlet hole 402 communicates with the corresponding air hole 101, and the air hole 101 communicating with the air inlet hole 402 is the air inlet, so that the air pressure is greater.

[0039]

[0040] ​In another embodiment, at least two air inlet holes 402 are arranged on the same vertical line according to the needs, so that multiple air inlet holes 402 are in communication with the corresponding air holes 101, thereby realizing the simultaneous inflation of multiple inflation devices.

[0041] The valve core 400 is the core component of the control valve, and its rotating design enables the control valve to adjust the air flow path according to different massage needs. The hollow air cavity 401 inside the valve core 400 is used to store and transmit gas, and the air inlet end serves as the gas inlet and is connected to the external inflation device. The design of multiple air inlet holes 402 of different heights enables the valve core 400 to align with different air hole groups 101 on the outer shell 100 during rotation, thereby achieving precise control over different massage areas. This design not only improves the flexibility of the control valve but also enhances its adaptability, enabling it to meet the massage needs of different users.

[0042] The servo motor 300 in this embodiment is connected to one end of the valve core 400 through the shaft coupling 301 for driving rotation. The servo motor 300 serves as the power source of the control valve and is connected to the valve core 400 through the shaft coupling 301, ensuring stable transmission of power. The servo motor 300 has precise control performance and can accurately control the rotation angle and speed of the valve core 400 according to pre-set programs or user instructions. This design enables the control valve to achieve complex massage movements and force adjustments, improving the comfort and effectiveness of the massage. At the same time, the use of the servo motor 300 simplifies the control system of the control valve, reducing manufacturing costs and maintenance difficulty.

[0043] The inflation device in this embodiment is an air bag, and in this embodiment, the air bag is divided into a massage air bag and a waist support air bag, which are respectively connected to air holes 101 of different heights for air intake and rotate with the valve core 400, thereby achieving the collision and contraction of the corresponding air bags. At the same time, the servo motor 300 can accurately adjust the collision of each air bag by adjusting the rotation angle, and can also adjust the air intake efficiency according to the contact area of the air inlet hole 402 and the air hole 101.

[0044] The air nozzle 200 in this embodiment is located at the other end of the valve core 400 and is connected to the air inlet end of the air cavity 401 for air supply. The air nozzle 200 serves as the connecting component between the control valve and the inflation device, and its design ensures smooth transmission of gas. The air nozzle 200 is connected to the air inlet end of the air cavity 401 of the valve core 400, so that the gas in the inflation device can enter the air cavity 401 of the valve core 400 through the air nozzle 200, and then enter the massage waist support through the air inlet hole 402 and the air hole 101 on the outer shell 100. The selection and installation position of the air nozzle 200 are crucial to the performance of the control valve, as they directly affect the flow and pressure of the gas, thereby affecting the massage effect.

[0045] In this embodiment, bearings 500 are arranged between the valve core 400 and the outer housing 100 at the upper and lower ends respectively; the arrangement of the bearings 500 has an important influence on the operation stability and durability of the control valve. The arrangement of the bearings 500 between the valve core 400 and the outer housing 100 can effectively reduce the friction and wear between the two, improving the operation efficiency of the control valve. At the same time, the bearings 500 can also bear the radial and axial forces generated during the rotation of the valve core 400, ensuring the stability and positioning accuracy of the valve core 400. This design not only prolongs the service life of the control valve, but also improves its reliability and stability.

[0046] In this embodiment, sealing rings 403 are arranged between the different height intake holes 402 in the valve core 400, and the arrangement of the sealing rings 403 is crucial for the air tightness of the control valve. The arrangement of the sealing rings 403 between the different height intake holes 402 in the valve core 400 can effectively prevent gas leakage during the rotation of the valve core 400. In addition, the valve core 400 is also provided with an exhaust passage 404 connected with the gas cavity 401, for discharging unnecessary gas.

[0047] In this embodiment, the valve core 400 is provided with an exhaust passage 404 on the plane corresponding to the intake hole 402, the exhaust passage 404 penetrates the valve core 400 and does not communicate with the gas cavity 401 and the intake hole 402, and the distance between the two ends of the exhaust passage 404 and the two gas holes 101 on the corresponding plane is the same; the arrangement of the exhaust passage 404 is the key to the exhaust function of the control valve. The arrangement of the exhaust passage 404 on the plane corresponding to the intake hole 402 in the valve core 400 makes the exhaust passage 404 align with the two gas holes 101 on the outer housing 100 when the valve core 400 rotates to a certain position, thereby realizing the discharge of gas. The design of the exhaust passage 404 needs to consider factors such as its length, width and depth to ensure that it can meet the exhaust requirements of the control valve. At the same time, the distance between the two ends of the exhaust passage 404 and the two gas holes 101 on the corresponding plane is the same, which ensures the docking accuracy and sealing performance of the exhaust passage 404, and improves the performance and reliability of the control valve.

[0048] The exhaust channel 404 is just connected with two air holes 101, and the two air holes 101 are used for air intake and air exhaust respectively. When the two air holes 101 are connected under the action of the exhaust channel 404, the gas in the inflation device flows to the air exhaust hole 101, realizing air exhaust. This design enables the control valve to realize the circulation of the gas during the massage process, thereby improving the comfort and effect of the massage. When the air intake hole 402 is aligned with the corresponding air hole 101, the gas in the inflation device enters the massage waist support through the air intake hole 402, providing power for the massage. When the exhaust channel 404 is aligned with the two air holes 101, the gas in the massage waist support is exhausted through the exhaust channel 404, realizing the circulation of the gas. This design not only improves the massage effect of the control valve, but also enhances its adaptability and flexibility.

[0049] In this embodiment, the two air holes 101 in the same group are used for air intake and air exhaust respectively, and the distance between the two air holes 101 is less than the diameter. This design makes the control valve more compact in structure and easy to operate. The two air holes 101 in the same group are used for air intake and air exhaust respectively, ensuring smooth flow of the gas during the massage process. The design that the distance between the two air holes 101 is less than the diameter enables the valve core 400 to be more easily aligned with the two air holes 101 during rotation, thereby improving the alignment accuracy and sealing performance of the control valve. This design not only improves the performance and reliability of the control valve, but also enhances its adaptability and flexibility.

[0050] In this embodiment, the air intake on the outer shell 100 is used to connect the inflation device. The air intake design on the outer shell 100 is a connection interface between the control valve and the inflation device, and its position, size and shape need to consider the connection requirements of the inflation device and the use requirements of the control valve.

[0051] In summary, the control valve in this embodiment has the following advantages:

[0052] Structurally, the reciprocating contact motion is changed to rotary motion, improving the noise problem of the valve group during work, improving passenger comfort, and reducing noise. Since the mechanical valve uses a rotary motion structure, there is no mechanical collision in reciprocating motion, so the working noise of the valve group is relatively small, which can provide the comfort of the massage and waist support system.

[0053] In principle, the electromagnetic induction is changed to a pure mechanical structure, reducing product cost and improving product market competitiveness. Since the working principle of the mechanical valve is a mechanical structure, there is no copper winding in the electromagnetic valve, and there is no memory metal in the memory valve, so the cost of the valve group is relatively low, thereby improving the product competitiveness.

[0054] Structurally, the reciprocating contact motion is changed to rotary motion, the frequency of air path switching is improved, the product comfort is improved, and the running speed can be greatly higher than the reciprocating motion of the previous valve group due to the servo motor 300 and the mechanical rotating mechanism, the improvement of the air exchange speed can greatly improve the comfort of the massage and waist support system, thereby improving the product competitiveness.

[0055] The existing electromagnetic valve needs to use copper winding conductor to generate electromagnetic force to realize the opening and closing function of the valve group, and the cost is high. The mechanical valve designed in the case realizes innovation in principle, realizes the opening and closing function of the valve group by using the precise cooperation and different collocation of the mechanical valve core 400 and the air inlet. Not only the cost is reduced, but also the product stability is improved.

[0056] At present, the market requirements for passenger comfort are getting higher and higher, and the requirements for the massage force and frequency of the massage system are also getting more and more demanding. Due to the principle of electromagnetic attraction, the traditional electromagnetic valve has low charging and discharging frequency, and the mechanical valve designed in the case can realize various charging and discharging frequencies by rotating the servo motor 300, thereby improving the comfort of passengers.

[0057] The above description is an explanation of the utility model, not a limitation of the utility model, the scope defined by the utility model is referred to the claims, and any form of modification can be made within the protection scope of the utility model.
