Description

Technical Field

[0001] This utility model discloses a massage seat controller and a vehicle, belonging to the field of automotive seat control technology. Background Technology

[0002] In the existing pneumatic control system of massage chairs, the core controller usually needs to integrate multiple pneumatic valve components to achieve inflation / deflation control of different airbags in the chair.

[0003] In traditional controllers, the pneumatic valve components are often scattered in different locations inside the seat, or although they are integrated on the same circuit board, the layout is messy. This results in complex connecting pipes, large space occupation, and low assembly efficiency. The unreasonable internal structure design of the controller leads to a chaotic air circuit layout, which not only increases airflow resistance, but may also cause air leakage risks due to pipe bends and friction, thus reducing system reliability. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the valve components in existing controllers are scattered or have a messy layout, resulting in complex pipelines and large space occupation. The invention proposes a massage seat controller and vehicle.

[0005] The problem to be solved by this utility model is achieved by the following technical solution:

[0006] A massage chair controller includes: a controller housing assembly having a mounting cavity; and a circuit board assembly disposed within the mounting cavity and connected to the controller housing assembly. The circuit board assembly includes a circuit board body, a pneumatic massage valve assembly, a pneumatic lumbar support valve assembly, and an active side wing valve assembly. The pneumatic massage valve assembly, the pneumatic lumbar support valve assembly, and the active side wing valve assembly are respectively spaced apart on the circuit board body. The pneumatic massage valve assembly and the pneumatic lumbar support valve assembly are connected to an external air pump through a first air inlet, and the active side wing valve assembly is connected to an external air pump through a second air inlet. The first air inlet and the second air inlet are spaced apart.

[0007] Furthermore, the massage chair controller also includes: sound insulation cotton disposed within the mounting cavity, and the sound insulation cotton is connected to at least one of the pneumatic massage valve assembly, pneumatic lumbar support valve assembly, active side wing valve assembly, and controller housing assembly.

[0008] Furthermore, the massage chair controller also includes: positioning units, of which multiple positioning units are arranged circumferentially on the circuit board body.

[0009] Furthermore, the positioning unit includes: a positioning unit, which has a limiting space for cooperating with the circuit board body, and multiple limiting protrusions are provided on the positioning unit inside the limiting space, with the multiple limiting protrusions spaced apart; and a limiting post, which is provided in the limiting space and cooperates with the circuit board body.

[0010] Furthermore, the cross-section of the limiting protrusion includes a triangle or a semicircle.

[0011] Furthermore, the pneumatic massage valve assembly includes multiple pneumatic massage valve units, which are spaced apart; the pneumatic lumbar support valve assembly includes multiple pneumatic lumbar support valve units, which are spaced apart; and the multiple pneumatic massage valve units and the multiple pneumatic lumbar support valve units are connected through a first channel.

[0016] The advantages of this invention compared to existing technologies are as follows:

[0017] This utility model discloses a massage seat controller and vehicle, which integrates three valve components on the same circuit board and sets them apart, reducing the redundant pipelines and installation space required for dispersed layout, making the overall controller structure more compact and easier to assemble, and reducing the space occupied inside the seat. The first and second air inlets supply air to the valve components with different functions, avoiding mutual interference between airflows from different air paths, ensuring stable air pressure when each functional module is working, and improving the adjustment accuracy of massage intensity, lumbar support, and side wing clamping.

Detailed Implementation

[0025] The following is based on the appendix Figure 1-6 Further explanation of this utility model:

[0026] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] like Figures 1-4 As shown, the first embodiment of this utility model provides a massage chair controller based on the prior art, including: a controller housing assembly and a circuit board assembly 30. The controller housing assembly has a mounting cavity, and the circuit board assembly 30 is disposed in the mounting cavity and connected to the controller housing assembly. The circuit board assembly 30 includes a circuit board body 310, a pneumatic massage valve assembly, a pneumatic lumbar support valve assembly, and an active side wing valve assembly. The pneumatic massage valve assembly, the pneumatic lumbar support valve assembly, and the active side wing valve assembly are respectively spaced apart on the circuit board body 310. The pneumatic massage valve assembly and the pneumatic lumbar support valve assembly are connected to an external air pump through a first air inlet 303, and the active side wing valve assembly is connected to an external air pump through a second air inlet 309. The first air inlet 303 and the second air inlet 309 are spaced apart.

[0030] In this embodiment, the pneumatic massage valve assembly, pneumatic lumbar support valve assembly, and active side wing valve assembly are integrated onto the same circuit board body 310 and spaced apart. Combined with the mounting cavity structure of the controller housing assembly, this achieves a compact layout of the functional valve assemblies, significantly reducing the overall space occupied and simplifying the assembly process. Simultaneously, the spaced arrangement of the first air inlet 303 and the second air inlet 309 allows the pneumatic massage valve assembly, pneumatic lumbar support valve assembly, and active side wing valve assembly to form independent air supply circuits, effectively avoiding airflow interference between different functional modules during operation and ensuring air pressure stability and adjustment accuracy. This integrated design combined with the independent air path layout not only optimizes the air path to reduce the risk of leakage but also facilitates subsequent maintenance and repair of the circuit board assembly 30 due to its clear structure, significantly improving the overall reliability and performance of the controller.

[0031] Furthermore, the massage chair controller also includes: sound insulation cotton 40, which is disposed within the mounting cavity and connected to at least one of the pneumatic massage valve assembly, pneumatic lumbar support valve assembly, active side wing valve assembly, and controller housing assembly. The sound insulation cotton 40 added to the massage chair controller, disposed within the mounting cavity and connected to at least one of the pneumatic massage valve assembly, pneumatic lumbar support valve assembly, active side wing valve assembly, and controller housing assembly, effectively absorbs the pneumatic and mechanical vibration noise generated during the operation of each valve assembly, significantly reducing the overall operating noise of the controller and improving the quietness of the massage chair during use. Simultaneously, the connection method between the sound insulation cotton 40 and the relevant components can also reduce vibration transmission between the valve assembly and the controller housing assembly through its own buffering characteristics, reducing the risk of component loosening after long-term use and further enhancing the structural stability and service life of the controller.

[0032] In one exemplary embodiment, such as Figure 5 As shown, the massage chair controller also includes a positioning unit 50, which comprises multiple units arranged circumferentially on the circuit board body 310. The multiple positioning units 50 included in the massage chair controller are arranged circumferentially on the circuit board body 310. This design provides a precise positioning reference for the circuit board assembly 30 within the mounting cavity of the controller housing assembly, ensuring the accurate positioning of the circuit board body 310 and its functional components such as the pneumatic massage valve assembly, pneumatic lumbar support valve assembly, and active side wing valve assembly during assembly. This avoids misalignment of air circuit connections or interference between components due to installation offset. Simultaneously, the circumferentially spaced positioning units 50 evenly distribute the fixing stress on the circuit board assembly 30, enhancing its stability in connection with the controller housing assembly, reducing loosening caused by vibration and other factors during long-term use, and further ensuring the reliability of the air circuit connections between each valve assembly and the first air inlet 303 and the second air inlet 309.

[0033] Furthermore, the positioning unit 50 includes: a positioning unit 501, which is provided with a limiting space 502 for cooperating with the circuit board body 310. The positioning unit 501 inside the limiting space 502 is provided with a plurality of limiting protrusions 504, which are spaced apart, and a limiting post 503, which is provided inside the limiting space 502 and cooperates with the circuit board body 310.

[0034] In this embodiment, the positioning unit 501, by cooperating with the circuit board body 310 through the setting of the limiting space 502, can effectively constrain the circuit board body 310 as a whole; while the multiple spaced limiting protrusions 504 inside the limiting space 502 can further enhance the limiting effect on the edge of the circuit board body 310, preventing it from shifting laterally during assembly or use; at the same time, the limiting post 503 located in the limiting space 502 cooperates with the circuit board body 310 to accurately position the circuit board body 310 longitudinally, ensuring that its installation position with the controller housing assembly is accurate. This combination structure of "limiting space 502 + limiting protrusion 504 + limiting post 503" makes the positioning unit 50 more stable and reliable in positioning the circuit board body 310. It effectively avoids the air circuit connection problem caused by positional deviation between the pneumatic massage valve assembly, pneumatic waist support valve assembly, active side wing valve assembly, etc. on the circuit board assembly 30 and the first air inlet 303 and the second air inlet 309, and improves the overall assembly accuracy and working stability of the controller.

[0035] In an exemplary embodiment, the cross-section of the limiting protrusion 504 includes a triangle or a semi-circle. The triangular cross-section of the limiting protrusion 504 allows for point-contact limiting with the circuit board body 310 through its sharp edges, enhancing the locking effect and effectively preventing lateral slippage. The semi-circular cross-section of the limiting protrusion 504, on the other hand, contacts the circuit board body 310 through its smooth curved surface, ensuring the limiting function while reducing wear on the edges of the circuit board body 310, thus preventing damage to the circuit board due to long-term assembly or vibration. Both shapes can be combined with the limiting space 502 and limiting post 503 of the positioning unit 501 to further improve the positioning accuracy and stability of the circuit board body 310, ensuring accurate and reliable airway connections between functional components such as the pneumatic massage valve assembly and the pneumatic waist support valve assembly and the first air inlet 303 and the second air inlet 309.

[0036] In this embodiment, the pneumatic massage valve assembly includes multiple pneumatic massage valve units 302, which are spaced apart. The pneumatic lumbar support valve assembly includes multiple pneumatic lumbar support valve units 304, which are spaced apart. The multiple pneumatic massage valve units 302 and the multiple pneumatic lumbar support valve units 304 are connected through a first channel 305.

[0037] The pneumatic massage valve assembly employs multiple spaced-apart pneumatic massage valve units 302, and the pneumatic lumbar support valve assembly employs multiple spaced-apart pneumatic lumbar support valve units 304. Both are connected via a first channel 305. This design offers significant advantages: the multiple spaced-apart pneumatic massage valve units 302 and pneumatic lumbar support valve units 304 can respectively control the massage airbags and lumbar support airbags in different areas of the seat, achieving more precise zone control and improving the targeted nature of massage and lumbar support adjustments. Connecting them via the first channel 305 allows them to share the air source of the first air inlet 303, ensuring the air path is independent of the active side wing valve assembly while simplifying the air path layout for pneumatic massage and lumbar support functions and reducing pipeline redundancy. Furthermore, the spaced-apart valve units, combined with the connected first channel 305, avoid the poor heat dissipation problem caused by centralized valve assembly arrangement and ensure consistent air pressure, improving the synchronicity and stability of the valve unit actions, thereby optimizing the overall effect of massage and lumbar support adjustment.

[0038] Furthermore, the active side wing valve assembly includes a first active side wing valve 306 and a second active side wing valve 308, which are spaced apart and connected through a second channel 307. The spaced arrangement of the first active side wing valve 306 and the second active side wing valve 308 allows for precise control of the side wing airbags on both sides of the seat, achieving independent and symmetrical clamping adjustment and improving the fit of the user's comfort. The second channel 307 allows both to share the air source of the second air inlet 309, maintaining the independence of air supply from the pneumatic massage valve assembly and the pneumatic lumbar support valve assembly while simplifying the internal air circuit structure of the active side wing function and reducing the complexity of pipeline connections. In addition, the spaced arrangement combined with the connected second channel 307 avoids the space congestion and heat dissipation problems caused by the centralized arrangement of valve assemblies, and ensures the balance of air supply pressure on both side wing valves, ensuring the synchronicity and coordination of the operation of the first active side wing valve 306 and the second active side wing valve 308, further optimizing the adjustment accuracy and user experience of the active side wing.

[0039] In one exemplary embodiment, the circuit board assembly 30 further includes a connection terminal 301, which is connected to the circuit board body 310. The connection terminal 301 is spaced apart from the pneumatic massage valve assembly, the pneumatic waist support valve assembly, and the active side wing valve assembly. The connection terminal 301 serves as a transfer component between external control signals and the internal valve assemblies. Maintaining a distance between it and each valve assembly avoids electromagnetic interference during signal transmission, ensuring accurate transmission of control commands to the pneumatic massage valve unit 302, the pneumatic waist support valve unit 304, the first active side wing valve 306, and the second active side wing valve 308. Simultaneously, the spaced arrangement makes the layout of the connection terminal 301 and each valve assembly clearer, facilitating wiring operations and subsequent maintenance, and reducing the risk of short circuits caused by cross-wiring. Combined with the air path layout on the circuit board body 310, this further enhances the overall structural rationality and operational reliability of the circuit board assembly 30.

[0040] In the above embodiments, such as Figure 6 As shown, the controller housing assembly includes: a lower housing 20, which is connected to the sound insulation cotton 40, the circuit board assembly 30 and the positioning unit 50. The lower housing 20 has a terminal slot 201 for engaging with the connection terminal 301. An upper housing 10 is fastened to the lower housing 20 to form an installation cavity. The lower housing 20 is directly connected to the sound insulation cotton 40, circuit board assembly 30, and positioning unit 50, providing a stable mounting base for these core components. Combined with the mounting cavity formed by the upper housing 10 after snapping shut, it provides comprehensive protection for the internal circuit board body 310, pneumatic massage valve assembly, pneumatic waist support valve assembly, and active side wing valve assembly, isolating them from external dust, moisture, and other interference. The terminal slot 201 on the lower housing 20 precisely matches the connecting terminal 301, providing independent mounting space for the connecting terminal 301, facilitating external wiring access, and preventing collisions or interference with other components during wiring. The snap-fit ​​structure between the upper housing 10 and the lower housing 20 simplifies the overall assembly process while ensuring the sealing of the mounting cavity. Combined with the sound insulation effect of the sound insulation cotton 40, it further reduces noise leakage from the internal valve assembly during operation, improving the overall protection performance and user experience of the controller.

[0041] The second embodiment of this utility model provides a vehicle based on the first embodiment, including a vehicle body and a massage seat controller as described in the first embodiment.

[0042] This embodiment integrates a massage seat controller with features such as compact structure, stable air supply, and low-noise operation into the vehicle body, providing passengers with a superior massage experience. The mounting cavity formed by the upper housing 10 and lower housing 20 of the controller housing assembly protects internal components such as the circuit board assembly 30 from vibration and dust during vehicle operation, ensuring stable operation in complex in-vehicle environments. The sound insulation cotton 40 effectively reduces the operating noise of the valve assembly, and together with the vehicle's sound insulation design, enhances the quietness of the vehicle interior. The precise positioning unit 50 and reasonable air circuit layout ensure reliable operation of the massage function, allowing passengers to obtain comfortable massage, lumbar support, and side wing wrapping sensation through the pneumatic massage valve assembly, pneumatic lumbar support valve assembly, and active side wing valve assembly during driving, further enhancing the vehicle's ride comfort and humanized design.
