Description

Technical Field

[0001] This utility model discloses a seat massage controller 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] During vehicle operation, the environment is extremely complex and challenging, and vibration and impact are unavoidable and constant occurrences. On highways, road surfaces vary greatly, from gravel roads to bumpy sections with potholes and speed bumps, all of which cause varying degrees of vibration. When a vehicle starts, accelerates, brakes suddenly, or turns, the interior of the vehicle body experiences impacts due to inertial forces. Furthermore, the operation of the vehicle's engine, tire friction with the road surface, and the movement of surrounding air all contribute to continuous sources of vibration.

[0004] For seat massage controllers installed inside vehicles, the chips on their PCBA boards face a severe test. Without effective restraints, the chips are highly susceptible to displacement on the PCBA board due to repeated vibrations and impacts from long-term vehicle operation. Once the chip becomes loose, the connection between its pins and the pads on the PCBA board becomes precarious. Summary of the Invention

[0045] The following is based on the appendix Figure 1-5 Further explanation of this utility model:

[0046] 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.

[0047] 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.

[0048] 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.

[0049] like Figure 1-3As shown, the first embodiment of this utility model provides a seat massage controller based on the prior art, including: a lower controller housing 3, the lower controller housing 3 having a first positioning space; a PCBA board assembly, one side of the PCBA board assembly being fitted into the first positioning space; and an upper controller housing 1, the upper controller housing 1 having a second positioning space, the upper controller housing 1 being fastened to the PCBA board assembly 2, the first positioning space being connected to the second positioning space. The other side of the PCBA board assembly is fitted into the second positioning space, and the upper controller housing 1 and the lower controller housing 3 are snap-fitted together, limiting the PCBA board assembly 2 within the first positioning space and the second positioning space.

[0050] This embodiment embeds the PCBA board assembly within the first positioning space of the lower housing and the second positioning space of the upper housing of the controller, and secures it using a snap-fit ​​mechanism. This prevents the PCBA board assembly from shifting under vibrations and impacts generated during vehicle operation, thus avoiding problems with the chips due to displacement and ensuring the stability of the chips during long-term vehicle operation. Even under the inertial forces caused by frequent vehicle starts, accelerations, sudden braking, and turning, as well as vibrations caused by engine operation, tire-ground friction, and airflow, the chips are less prone to loosening, reducing the risk of chip pin and pad connection failure and ensuring the normal operation of the seat massage controller.

[0051] Furthermore, such as Figure 2 and Figure 3 As shown, a first honeycomb reinforcing rib 31 is provided at the bottom of the first positioning space, a wedge-shaped block 35 is provided on the outer side of the lower housing 3 of the controller, a second honeycomb reinforcing rib 13 is provided at the bottom of the second positioning space, and a snap-fit ​​hole 11 is provided on the outer side of the upper housing 1 of the controller to engage with the wedge-shaped block 35. The first honeycomb reinforcing rib 31 and the second honeycomb reinforcing rib 13 can increase the structural strength of the bottom of the corresponding positioning spaces of the lower and upper housings of the controller. The honeycomb structure design can effectively improve the compressive strength and deformation resistance of the housing without adding too much weight, better protect the PCBA board assembly embedded in the positioning space, and enable it to withstand greater external forces without damage or deformation when subjected to vibration and impact during vehicle operation, further ensuring the stability of components such as chips on the PCBA board.

[0052] like Figure 4 and Figure 5As shown, the PCBA board assembly 2 includes a PCB board 25 and four positioning components 22. Each positioning component 22 has a limiting space, and the four corners of the PCB board 25 are positioned within these limiting spaces. Several electronic components 23 are mounted on the PCB board 25. A pneumatic assembly 24 is connected to these electronic components 23. One end of the pneumatic assembly 24 has a first connection port 21, and its side has several connection ports 241. The bottom of the lower housing 3 of the controller has a second connection port 32 connected to the first connection port 11, and the side of the lower housing 3 has an air inlet 33 communicating with the second connection port 32. The four positioning components in the PCBA board assembly have limiting spaces, and the four corners of the PCB board are positioned within these four limiting spaces. This design enables precise positioning and stable installation of the PCB board within the lower housing of the controller. During vehicle operation, vibrations and impacts are frequent and complex. Precise positioning and stable installation effectively prevent the PCB board from shifting or shaking within the housing, thus avoiding damage to electronic components due to collisions and friction, and ensuring the reliability and stability of the PCBA board assembly. This structural design organically integrates the PCBA board assembly, pneumatic components, and the lower housing of the controller, resulting in a compact structure and efficient space utilization for the entire seat massage controller. Within the limited space of the vehicle interior, this compact structure not only facilitates installation and layout but also reduces the probability of malfunctions caused by interference between components, improving the overall performance and reliability of the controller.

[0053] In this embodiment, the lower housing 3 of the controller is provided with a first port limiting groove 36 for limiting a plurality of the connection ports 241, and the upper housing 1 of the controller is provided with a second port limiting groove 14 for limiting a plurality of connection ports 241. The first port limiting groove 36 and the second port limiting groove 14 can precisely limit the connection ports 241 of the pneumatic component 24 from the upper and lower sides of the controller, respectively. This ensures that the connection ports will not be displaced due to vibration or impact during vehicle operation, keeps the connection between the pneumatic component and other components stable, and avoids problems such as loose air circuit connection and air leakage caused by shaking or displacement of the connection ports, thus ensuring the normal operation of the pneumatic system of the seat massage controller.

[0054] In one exemplary embodiment, the bottom of the upper housing 1 of the controller is provided with positioning grooves 12 that engage with a plurality of electronic components 23. The positioning grooves 12 provide precise positioning for the electronic components 23, ensuring that each electronic component is accurately installed in a predetermined position. When the PCBA board assembly is installed into the upper housing of the controller, the electronic components can correspond one-to-one with the positioning grooves, which helps improve the accuracy and efficiency of assembly and avoids circuit connection errors or functional abnormalities caused by deviations in the installation position of the electronic components.

[0055] In this embodiment, the seat massage controller further includes: adhesive-backed foam 4, which is disposed on the PCB board 25, and sound-absorbing sponge 5 disposed on the adhesive-backed foam 4. Since the sound-absorbing sponge itself also has a certain degree of elasticity and cushioning capacity, its layering on the adhesive-backed foam further enhances the cushioning protection of the PCB board 21. When the vehicle encounters strong bumps or impacts, the sound-absorbing sponge and adhesive-backed foam work together to better absorb and disperse external forces, reducing the impact on the PCB board and its electronic components, minimizing the risk of damage caused by external forces, and extending the service life of the electronic components and controller.

[0056] Furthermore, the lower housing 3 of the controller is provided with positioning holes 34 at both ends for connection to the vehicle body. The positioning holes 34 help installers accurately determine the installation position of the seat massage controller on the vehicle body. During installation, by cooperating with corresponding mounting structures on the vehicle (such as bolts), the controller can be ensured to be installed in the predetermined position, guaranteeing its accurate relative position with other vehicle components and avoiding functional abnormalities or interference with other components due to installation position deviations.

[0057] The second embodiment of this utility model provides a vehicle based on the first embodiment, including a seat massage controller, and the seat pneumatic lumbar support controller is the same as the seat massage controller described in the first embodiment. Because the seat massage controller is specifically designed for the complex driving environment of vehicles, its reliability and stability are improved through various structural optimizations (such as honeycomb reinforcing ribs, port limiting grooves, positioning grooves, etc.). This makes it less likely for seat massage-related functions to malfunction during long-term vehicle use, reducing after-sales maintenance costs and user inconvenience.

[0058] 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.
