Description

Technical Field

[0001] This utility model discloses a pneumatic lumbar support controller for a seat and a vehicle, belonging to the field of automotive seat technology. Background Technology

[0002] A pneumatic lumbar support is a car seat comfort feature that provides lumbar support through air pressure regulation to enhance driving comfort. The working principle of a pneumatic lumbar support is based on a pneumatic system. This system uses an air pump to generate compressed air, which is then distributed as needed to individual airbags within the seat back via a pressure-distributing valve. The airbags inflate when inflated, providing firm support for the lumbar region; they deflate when deflated, relaxing and massaging the lower back. An electronic controller precisely controls the inflation and deflation process of the airbags, achieving dynamic adjustment of lumbar support and massage.

[0003] Pneumatic lumbar supports adjust their height and position by inflating and deflating air bags. The inflation and deflation of these air bags are mainly achieved through solenoid valves. Since pneumatic lumbar supports typically consist of multiple air bags, their control system is correspondingly configured as a solenoid valve group controller with multiple solenoid valves. However, most solenoid valves on the market are complex in structure and inconvenient to assemble, often requiring specialized connectors to combine multiple solenoid valves. This results in a large controller size and difficulties in disassembly and assembly. Utility Model Content

Detailed Implementation

[0026] The following is based on the appendix Figure 1-9 Further explanation of this utility model:

[0027] 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.

[0028] 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.

[0029] 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.

[0030] like Figure 1-5As shown, the first embodiment of this utility model provides a pneumatic lumbar support controller for a seat based on the prior art. It includes a lower housing 6, with honeycomb-shaped reinforcing ribs 61 at the bottom inner side. A PCBA board assembly is disposed inside the lower housing 6, and sound-absorbing cotton 3 and foam 2 are disposed on the PCBA board assembly. An air passage 66 is provided at one end of the lower housing 6, which is connected to a solenoid valve on the PCBA board assembly. The PCBA board assembly, sound-absorbing cotton 3, and foam 2 are sealed and fastened within the lower housing 6 by an upper housing 1. One end of the air passage 66 is connected to the outside, and the other end of the air passage 66 is sealed by a baffle 11 on the upper housing 1. This application, through the above structure, facilitates the combined use of multiple solenoid valves, effectively reducing the difficulty of disassembling and assembling the solenoid valve assembly and the overall design of the seat lumbar support controller, achieving the effects of simple structure, high integration, and small size.

[0031] Furthermore, the PCBA board assembly includes a PCBA board 75. A first solenoid valve group 73 and a second solenoid valve group 74 are respectively disposed near their two side edges on the PCBA board 75. A third solenoid valve group 72 is disposed on one side of the PCBA board 75 near the end of the second solenoid valve group 74. One end of the third solenoid valve group 72 is arranged adjacent to one end of the first solenoid valve group 73. A terminal block 71 is installed on one end of the PCBA board 75. Sound-absorbing cotton 3 is installed on the PCBA board 75 between the first solenoid valve group 73 and the second solenoid valve group 74. The foam 2 is attached to the top of the third solenoid valve group 72, the first solenoid valve group 73, and the second solenoid valve group 74. Installed between the first and second solenoid valve groups, the sound-absorbing cotton can directly absorb and block the mechanical vibration and fluid noise generated when the two solenoid valve groups are working, reducing the transmission of noise to the surrounding environment, lowering the overall noise level of the equipment during operation, and improving the acoustic conditions of the working environment. PCBA boards typically integrate various electronic components and circuits. Sound-absorbing cotton can play a certain role in buffering, reducing the impact of vibration generated by the solenoid valve assembly on the components and circuits on the PCBA board, reducing the risk of component loosening or desoldering caused by vibration, and improving the stability and reliability of the circuit system.

[0032] Sound-absorbing cotton generally has a certain degree of thermal insulation, which can, to some extent, prevent the heat generated by the solenoid valve assembly during operation from being rapidly transferred to the PCBA board. This helps maintain the operating temperature of electronic components on the PCBA board within a reasonable range, preventing overheating from adversely affecting circuit performance and lifespan, and thus playing a role in auxiliary thermal management. Some sound-absorbing cotton may also have certain electromagnetic shielding properties, which can reduce the impact of electromagnetic interference generated by the solenoid valve assembly on other electronic components and circuits on the PCBA board to a certain extent, improving the electromagnetic compatibility of the entire system.

[0033] The foam, when bonded to the top of the three solenoid valve assemblies, creates a good seal, preventing dust and debris from entering the assembly and affecting its normal operation. This reduces the probability of malfunctions and extends the lifespan of the solenoid valve assemblies. It also buffers vibrations during operation, reducing the impact on the valves themselves and their connections with other components. This not only helps protect the structural integrity of the valve assemblies but also reduces wear and fatigue caused by vibration, improving the stability and durability of the entire system. The foam typically has good insulation properties, forming an insulating layer between the solenoid valve assemblies and other components, preventing electrical short circuits and leakage, and improving the electrical safety of the equipment. The foam also has a certain heat conduction regulating effect, allowing for more even heat distribution among the three solenoid valve assemblies, preventing localized overheating, and helping to maintain the valve assemblies within a suitable operating temperature range, thus improving their efficiency and reliability. In addition to the primary noise reduction function of the sound-absorbing cotton, the foam bonded to the top of the solenoid valve assemblies also provides auxiliary noise reduction, further absorbing and blocking noise emitted by the valve assemblies, making the equipment operate more quietly.

[0034] like Figure 6-9 As shown, an internal flow channel 64 is provided at the bottom of the lower housing 6. The two first internal flow channel connection ends 67 of the internal flow channel 64 are connected to the air passage 66. The PCBA assembly also includes an air intake pipe 4. The first air intake pipe end 41 of the air intake pipe 4 is connected to the first solenoid valve group 73. The third air intake pipe end 43 of the air intake pipe 4 is connected to one end of the second solenoid valve group 74. The second air intake pipe end 42 of the air intake pipe 4 is connected to the second internal flow channel connection end 63 of the internal flow channel 64. The fourth air intake pipe end 44 of the air intake pipe 4 is connected to the third internal flow channel connection end 65 of the internal flow channel 64. The connection between the internal flow channel 64 and the air intake pipe 4 allows gas to be evenly distributed from the air intake pipe to the first solenoid valve group 73, the second solenoid valve group 74, and the internal flow channel of the lower housing through different connection ends, ensuring that each component receives a stable and appropriate amount of gas, which helps the various parts of the system work in a coordinated manner.

[0035] The upper housing 1 has a first solenoid valve terminal mating part 12 on each side, and the lower housing 6 has a second solenoid valve terminal mating part 68 on each side. The first solenoid valve terminal mating part 12 and the second solenoid valve terminal mating part 68 form an assembly position that fits into the first solenoid valve group 73 and the second solenoid valve group 74.

[0036] The lower housing 6 has at least one wedge-shaped block 62 on each of its two sides, and the upper housing 1 has at least one limiting groove 13 on each of its two sides that mates with the wedge-shaped block 62. A rubber cover 5 is installed between the other end of the air passage 66 and the baffle 11. Multiple reinforcing ribs 69 are arranged from one end to the other inside the air passage 66. The arrangement of multiple reinforcing ribs can effectively enhance the structural strength of the air passage, improve its compressive strength, prevent the air passage from deforming or being damaged under gas pressure, and ensure the normal use of the air passage and the smooth flow of gas. The reinforcing ribs can guide and turbulent the gas flow in the air passage, making the gas distribution in the passage more uniform, reducing the occurrence of eddies and airflow turbulence, improving the efficiency and stability of gas flow, and helping to improve the overall performance of the equipment. The presence of reinforcing ribs changes the natural frequency of the air passage, reducing the risk of resonance caused by gas flow during equipment operation, avoiding structural damage and noise generation caused by resonance, and improving the reliability and comfort of equipment operation.

[0037] The second embodiment of this utility model provides a vehicle based on the first embodiment, including a seat pneumatic lumbar support controller, wherein the seat pneumatic lumbar support controller is the same as the seat pneumatic lumbar support controller described in the first embodiment.

[0038] Although embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. It can be applied to various fields suitable for this utility model. Other modifications can be readily implemented by those skilled in the art. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and examples shown and described herein.
