Description

Technical Field

[0001] This utility model relates to the technical field of automotive seat massage systems, and in particular to a low-noise, high-flow air pump for automotive seat massage systems. Background Technology

[0002] In car seat massage systems, the air pump, as a key component, plays a decisive role in the massage effect and user experience. However, air pumps currently used in car seat massage systems generally have some unresolved issues. First, noise is a significant problem. The interior of a car is a relatively enclosed space with high requirements for quietness, and the noise generated by the air pump during operation can seriously affect the comfort of passengers. Traditional air pumps generate considerable noise during operation due to gas flow and friction between components. For example, when the air pump supplies gas to the seat massage system, the moment the gas flows out of the pump, the high flow rate and lack of effective buffering produce a sharp airflow sound; at the same time, the friction between the mechanical parts inside the air pump during high-speed operation also generates noise. These noises are particularly noticeable in the quiet environment of the car, causing annoyance to passengers. Second, there is insufficient airflow. To achieve a good seat massage effect, the air pump needs to provide a sufficient and stable airflow. However, existing air pumps, under the same volume conditions, often cannot provide enough airflow, resulting in insufficient massage intensity and poor massage effect. Especially in some high-end car seat massage systems, the requirements for air pump flow are higher, and traditional air pumps are difficult to meet the gas flow changes required by complex and diverse massage modes.

[0003] In summary, existing air pumps used in car seat massage systems have many problems in terms of noise and flow rate, which seriously affect the performance and production efficiency of car seat massage systems. There is an urgent need to develop a new air pump technology to solve these problems. Utility Model Content

[0004] In view of the problems existing in the prior art, the present invention aims to provide a low-noise, high-flow air pump for a car seat massage system, so as to solve the problems of high noise and insufficient flow in the existing air pumps of the car seat massage system.

[0005] To achieve the above objectives, this utility model proposes a low-noise, high-flow air pump for an automotive seat massage system, comprising a motor and an air pump housing. The air pump housing includes a motor bracket, a cup holder, a lower air duct cover, and an upper air duct cover, connected sequentially from bottom to top. The motor bracket has air inlets at all four corners of its bottom surface and an eccentric wheel inside. The cup holder contains four cups arranged in a 2x2 matrix, with the lower ends of each cup fixedly connected by cup pushers and the top ends fixedly connected by connecting plates. The motor is fixedly mounted at the bottom of the motor bracket, and its output shaft passes through the motor bracket, extends into the interior of the motor bracket, and connects to the eccentric wheel. The eccentric wheel is connected to the cup holder via steel needles. The bowls and push blocks are connected. A gasket valve is embedded on the top surface of the lower cover of the air passage seat. An air passage is provided inside the lower cover of the air passage seat corresponding to the position of each leather bowl. A valve port is provided on the gasket valve corresponding to the position of each air passage. The upper cover of the air passage seat has four partitions inside. The four partitions are evenly distributed around the perimeter to divide the four corners of the upper cover of the air passage seat into an edge air chamber and to enclose the center of the upper cover of the air passage seat into a central air chamber. The top surface of each edge air chamber is open and tightly fitted with the gasket valve. The corresponding sides of the edge air chambers are connected to the central air chamber. An air outlet is also provided at the center of the top surface of the upper cover of the air passage seat. The bottom surface of the central air chamber is sealed by an air inlet cover plate, and the top surface of the central air chamber is connected to the air outlet.

[0006] In the above solution, the interior of the edge air chamber is equipped with several baffles to disrupt the gas flow direction. Adding baffle structures inside the air chamber disrupts the gas flow direction, creating a more complex flow path, preventing the formation of concentrated high-speed airflows, further reducing noise, and achieving low-noise operation of the air pump during operation, significantly improving the quietness and ride comfort inside the vehicle.

[0007] In the above solution: the motor bracket is fixed to the motor with four screws. The four screws pass through the inside of the motor bracket and are fixed to the motor, ensuring that the motor and the motor bracket are firmly connected. Moreover, the four screws are hidden inside the motor bracket, avoiding the messy feeling caused by exposed external screws.

[0008] In the above scheme: a recessed groove is provided on the top surface of the lower cover of the track seat, and a positioning post is provided in the recessed groove. The positioning post includes a circular positioning post, a rectangular positioning post, and a triangular positioning post. The gasket valve plate has positioning holes that match each positioning post one by one. The gasket valve plate is embedded in the recessed groove by cooperating with the positioning post through the positioning holes. The one-to-one matching design of the positioning post and positioning hole makes the installation process of the gasket valve plate simpler and faster. When assembling, the operator only needs to align the positioning hole on the gasket valve plate with the positioning post in the recessed groove and insert it. There is no need for complicated adjustments and calibrations, which effectively shortens the assembly time and improves production efficiency.

[0009] In the above solution: the air pump housing is cylindrical, and each outer wall of the air pump housing is equipped with a vertical retaining spring. The two ends of the vertical retaining spring are hooked onto the top and bottom surfaces of the air pump housing, respectively. These vertical retaining springs cooperate to securely connect the motor bracket, the rubber cup seat, the lower cover of the air passage seat, and the upper cover of the air passage seat. The use of vertical retaining springs simplifies the assembly process. Operators only need to accurately hook the vertical retaining springs onto the corresponding positions on the top and bottom surfaces of the air pump housing to simultaneously fix multiple components, eliminating the need for complex tools and cumbersome tightening steps, greatly improving assembly efficiency and reducing production costs. Specifically, the air pump housing has slots for the vertical retaining springs to be inserted.

[0010] In the above solution: the air inlet is connected to an air inlet pipe, and the air passage of the air inlet pipe is designed in a streamlined shape, so that the gas can enter the air pump more smoothly and reduce the air intake resistance. Thus, under the same working conditions, the amount of gas entering the air pump is significantly increased, providing a more sufficient air source for the seat massage system and effectively improving the massage effect.

[0011] In the above solution: the outer wall of the air pump housing is provided with multiple external positioning blocks, and the mounting bracket of the car seat massage system is provided with positioning grooves corresponding to each external positioning block. Each external positioning block can be snapped into its respective positioning groove to achieve pre-fixation of the air pump. When installing the air pump, simply align the external positioning block of the air pump with the positioning groove on the mounting bracket, and then complete the installation of the air pump through a simple snap-fit ​​or bolt connection. This method eliminates the need for complex positioning operations in the confined space inside the seat, greatly improving the convenience and speed of installation.

[0012] The beneficial effects of this utility model are:

[0013] 1. Traditional air pumps have an asymmetrical air chamber structure, leading to uneven gas flow, turbulence, increased noise, and hindered flow rate. This air pump employs a unique symmetrical air chamber structure, allowing for smoother gas flow within the chamber, reducing turbulence, lowering noise at its source, and optimizing the gas flow path to increase flow rate. 2. A central air chamber structure is added to the outlet chamber (including edge and center chambers). When gas flows out of the pump, direct high-speed ejection generates significant noise. The newly added central air chamber structure buffers the high-speed gas flow, effectively controlling the gas velocity and reducing noise from high-speed gas ejection. 3. The design of the air inlet cover inside the outlet chamber effectively isolates the air inlet and outlet spaces while maintaining stable outlet chamber volume. This helps maintain stable internal pressure within the air pump, further improving its reliability and stability, ensuring a continuous and stable supply of gas to the seat massage system under various operating conditions.

[0019] like Figure 1 As shown in Figure 5, a low-noise, high-flow air pump for a car seat massage system mainly consists of a motor 1 and an air pump housing.

[0020] The air pump housing includes a motor bracket 2, a leather cup seat 3, a lower cover of the air passage seat 4, and an upper cover of the air passage seat 5, which are connected sequentially from bottom to top. The bottom of the motor bracket 2 is provided with air inlets 6 at the four corners (using four evenly distributed air inlets, the air intake area is greatly increased, and the air intake flow rate is significantly improved compared with traditional air pumps. The sufficient air intake provides more air source for the air pump, ensuring that more gas can be provided to the seat massage system in the same amount of time, effectively improving the massage intensity and effect). It is also provided with an eccentric wheel 7 inside. The leather cup seat 3 is provided with four leather cups 8. The four leather cups 8 are arranged in a 2x2 matrix, and the lower ends of each leather cup 8 are fixedly connected by leather cup push blocks 9. The top ends of each leather cup 8 are fixedly connected by connecting plates 10.

[0021] The motor 1 is fixedly installed at the bottom of the motor bracket 2, and its output shaft passes through the motor bracket 2 and extends into the interior of the motor bracket 2, and is connected to the eccentric wheel 7. The eccentric wheel 7 is connected to the cup pusher block 9 through a steel needle (this connection structure is existing technology, the rotation of the motor 1 will drive the eccentric wheel 7 to rotate, thereby driving the cup 8 to move).

[0022] A gasket valve plate 11 is embedded on the top surface of the air passage seat cover 4. An air passage is provided inside the air passage seat cover 4 at the position corresponding to each leather cup 8. A valve port 12 is provided on the gasket valve plate 11 at the position corresponding to each air passage.

[0023] The airway seat cover 5 has four partitions 13 inside, which are evenly distributed around the perimeter to divide the four corners of the airway seat cover 5 into an edge air chamber 14 and surround the center of the airway seat cover 5 into a central air chamber 15. The top surface of each edge air chamber 14 is open and is tightly fitted with the gasket valve plate 11. The corresponding sides of the edge air chambers 14 are connected to the central air chamber 15. The top surface of the airway seat cover 5 is also provided with an air outlet 16. The bottom surface of the central air chamber 15 is sealed by an air inlet cover plate 17, and the top surface of the central air chamber 15 is connected to the air outlet 16.

[0024] Ideally, the motor bracket 2 is fixed to the motor 1 with four screws. The four screws pass through the inside of the motor bracket 2 and are fixed to the motor 1, ensuring that the motor 1 and the motor bracket 2 are firmly connected. The four screws are hidden inside the motor bracket 2, avoiding the messy feeling caused by exposed external screws.

[0025] Ideally, the top surface of the lower cover 4 of the airway seat is provided with a recess, and a positioning post is provided in the recess. The positioning post includes a circular positioning post, a rectangular positioning post, and a triangular positioning post. The gasket valve 11 is provided with a positioning hole 18 that matches each positioning post. The gasket valve 11 is embedded in the recess by engaging with the positioning post through the positioning hole. The one-to-one matching design of the positioning post and the positioning hole 18 makes the installation process of the gasket valve 11 simpler and faster. During assembly, the operator only needs to align the positioning hole 18 on the gasket valve 11 with the positioning post in the recess and insert it. There is no need for complicated adjustments and calibrations, which effectively shortens the assembly time and improves production efficiency.

[0026] Ideally, the interior of the edge air chamber 14 is equipped with several baffles to disrupt the direction of gas flow. Adding baffle structures inside the air chamber disrupts the gas flow direction, creating a more complex flow path, preventing the formation of concentrated high-speed airflows, further reducing noise, and achieving low-noise operation of the air pump during operation, significantly improving the quietness and ride comfort inside the vehicle.

[0027] Ideally, the air pump housing is cylindrical, with vertical retaining springs 19 on each outer wall. The two ends of each retaining spring 19 hook onto the top and bottom surfaces of the air pump housing, respectively. These retaining springs 19 work together to securely connect the motor bracket 2, the cup holder 3, the lower cover 4 of the air passage seat, and the upper cover 5 of the air passage seat. The use of the vertical retaining springs 19 simplifies the assembly process. Operators only need to accurately hook the retaining springs 19 onto the corresponding positions on the top and bottom surfaces of the air pump housing to simultaneously secure multiple components, eliminating the need for complex tools and cumbersome tightening steps. This significantly improves assembly efficiency and reduces production costs. Specifically, the air pump housing has slots for the vertical retaining springs 19 to be inserted.

[0028] Ideally, the air inlet 6 is connected to an air inlet pipe with a streamlined design, allowing air to enter the air pump more smoothly and reducing air intake resistance. This significantly increases the amount of air entering the air pump under the same working conditions, providing a more sufficient air source for the seat massage system and effectively improving the massage effect.

[0029] Ideally, the air pump housing should have multiple external positioning blocks on its outer wall, and the mounting bracket for the car seat massage system should have corresponding positioning slots for each external positioning block. Each external positioning block can be snapped into its respective slot to pre-fix the air pump. When installing the air pump, simply align the external positioning block of the air pump with the positioning slot on the mounting bracket, and then connect it using simple clips or bolts. This method eliminates the need for complex positioning operations within the confined space of the seat, greatly improving installation convenience.
