Description

Technical Field

[0001] This invention relates to the field of automotive seat massage technology, and more particularly to an automotive foot massage module and its S-shaped foot massage system. Background Technology

[0002] Most current car seat massage systems use airbags for inflation and deflation. This method is technologically mature and widely used. However, airbag massage suffers from limited deformation within a confined space, resulting in low massage intensity and a less noticeable subjective effect. Another type of massage is the mechanical massage structure, but mechanical massage occupies more space and is less commonly used. It also presents significant challenges to the arrangement of other functional structures such as seat ventilation, heating, and support. Furthermore, in the event of a car collision, mechanical massage structures can cause greater injury to occupants, increasing the risk of injury.

[0003] Therefore, existing car seat massage systems have the following drawbacks: 1. Airbag massage has low massage intensity and the subjective feeling effect is not obvious; 2. Mechanical massage structure occupies a large space; 3. In the event of a car collision, mechanical massage structure can cause greater harm to the human body, increasing the risk of injury to occupants. Summary of the Invention

[0004] In view of the above problems, the purpose of this invention is to provide a foot massage module for automobiles and its S-shaped foot massage system for performing foot massage in automobiles, solving the problems of mechanical massage occupying a large space and increasing the risk of injury to passengers, as well as the problems of low massage intensity and poor massage effect of air bag massage.

The arc-shaped protrusion is fixedly connected to the air bag support through the flexible hyperboloid portions on both sides. The shape of the arc-shaped protrusion corresponds to the upper support surface of the air bag. The inner side of the arc-shaped protrusion is attached to the upper support surface of the air bag. The top surface of the arc-shaped protrusion is fixedly connected to the bottom surface of the massage protrusions on the soft massage plate.

[0010] The massage controller controls the air pump to inflate the air bag. During the inflation and expansion of the air bag, the arc-shaped protrusion of the elastic base plate is driven, and the arc-shaped protrusion is supported and raised by the air bag to support the massage protrusion.

[0011] As a preferred embodiment of the present invention, the plurality of foot massage modules are arranged alternately in an S-shape to form a foot massage mechanism;

[0012] As a preferred embodiment of the present invention, the elastic substrate is made of TPE, and the arc-shaped protrusion is integrally formed with the flexible hyperboloid portions on both sides.

[0013] As a preferred embodiment of the present invention, the massage bumps include: an integrally formed top massage bump and a bottom support bump, wherein the bottom support bump is fixedly connected to the arcuate protrusion of the elastic substrate by ultrasonic welding.

[0014] As a preferred embodiment of the present invention, the air pump is fixed to the seat back frame by a clamping bracket, and the clamping bracket is provided with a positioning boss, which cooperates with the groove of the seat back frame.

[0015] As a preferred embodiment of the present invention, the air bag and the air bag support are connected by ultrasonic welding, the top surface of the air bag and the arc-shaped protrusion are fixedly connected by ultrasonic welding, the air bag support is provided with buckles around its perimeter for fixing to external components, and has a recess in the middle for positioning the air bag, and the two flexible hyperboloid portions are provided with unequally spaced mounting points on their edges, the unequally spaced mounting points are coupled to the corresponding mounting points of the air bag support, and the unequally spaced mounting points are used to prevent errors.

[0016] As a preferred embodiment of the present invention, the two soft connecting parts are positioned by the protrusions on their edges and the grooves provided on the air bag bracket, and are coupled to the corresponding mounting points of the air bag bracket by the snap-fit ​​parts on the edges of the soft connecting parts.

[0017] As a preferred embodiment of the present invention, the soft massage board is provided with a surface contact layer for contacting the feet, and the surface contact layer is provided with a plurality of acupoint massage points for foot acupoints.

[0018] Another object of the present invention is to provide an S-shaped foot massage system for automobiles, comprising: a foot massage module, a roller shutter module and a control module, wherein a plurality of the foot massage modules are arranged alternately in an S-shape on a massage mounting plate, the massage mounting plate is fixedly connected to the back of the front seat back frame of the automobile, and the roller shutter module is installed on the back of the front seat back frame of the automobile and is used to cover the foot massage system.

[0019] The roller shutter module includes: a motor, a roller shaft, a roller shutter door, and a roller shutter door mounting frame.

[0024] 2. A roller shutter module is installed on the back of the seat back. It is assembled with the seat foam and screwed to the seat back frame. The massage bumps on the soft massage plate of the foot massage module transmit the air bag's pushing action to the human foot in a regular manner, solving the pain points of low intensity and monotonous massage action of air bag massage.

[0026] 4. The airbag control module controls the inflation and deflation of the airbags based on the pressure values ​​of multiple airbags. The deformation of the airbags causes the flexible hyperboloid structure of the TPE elastic substrate to deform. The deformation of the flexible hyperboloid structure causes the soft massage plate to deform. Utilizing the lever principle, the combined deformation of the TPE elastic substrate and the soft massage plate can amplify the small deformation of the airbags, allowing the soles of the feet to feel the massage effect of the superimposed massage bumps on the soft massage plate, thus enhancing the massage experience.

However, it will be apparent that these embodiments may also be implemented without these specific details. In other instances, well-known structures and devices are shown in block diagram form for ease of description of one or more embodiments.

[0037] Example 1

[0038] See Figure 1-8 The foot massage module 12 provided in this embodiment includes: an air pump 1, an air valve 2, an air bag 3, an air bag support 4, an elastic base plate 5, a soft massage plate 6, an air pipe 7, and a wiring harness 8; the air pump 1 is connected to the air bag 3 through the air pipe 7, the air valve 2 is installed on the air pipe 7 connecting the air pump 1 and the air bag 3, and the air pump 1 is connected to the massage controller 9 through the wiring harness 8; the air bag 2 is fixedly connected to the air bag support 4, and the soft massage plate 6 is fixedly connected to the air bag support 4 and located directly above the air bag 3; the soft massage plate 6 includes: a massage protrusion 601 located in the middle, and a massage protrusion 601 located in the middle. The massage protrusion 601 is fixedly connected to the air bag support 4 via the soft connecting parts 602 on both sides of the point 601. The massage protrusion 601 and the soft connecting parts 602 on both sides are integrally formed. The massage protrusion 601 is internally composited with a hard material. The two soft connecting parts 602 have a certain elasticity and can be deformed under the pull of the massage protrusion 601. The two soft connecting parts 602 are positioned by the protrusions on the edge and the grooves provided on the air bag support 4, and are engaged with the corresponding mounting points of the air bag support 4 by the snap-fit ​​parts on the edge of the soft connecting parts 602. The TPE elastic substrate 5 is fixedly connected to the air bag support 4 and located between the air bag 3 and the soft massage plate 6. The TPE elastic substrate 5 includes: an arc-shaped protrusion 501 and flexible hyperboloid portions 502 located on both sides of the arc-shaped protrusion 501. The arc-shaped protrusion 501 is fixedly connected to the air bag support 4 through the flexible hyperboloid portions 502 on both sides. The arc-shaped protrusion 501 corresponds to the shape of the upper support surface of the air bag 3. The inner side of the arc-shaped protrusion 501 is attached to the upper support surface of the air bag 3. The top surface of the arc-shaped protrusion 501 is fixedly connected to the bottom surface of the massage protrusion 601. The flexible hyperboloid portion 502 has two curved bends. The deformation of the air bag 3 causes the flexible hyperboloid portion 502 of the TPE elastic substrate 5 to deform. The deformation of the flexible hyperboloid portion 502 of the TPE elastic substrate 5 causes the soft massage plate 6 to deform. Utilizing the lever principle, the joint deformation of the TPE elastic substrate 5 and the soft massage plate 6 can amplify the small deformation of the air bag 3, allowing the soles of the feet to feel the massage effect of the hard massage bumps 601 superimposed on the soft massage plate 6, thus enhancing the massage experience.

[0039] Furthermore, in this embodiment, multiple foot massage modules 12 are arranged alternately in an S-shape to form a foot massage mechanism;

[0040] Furthermore, in this embodiment, the TPE elastic substrate 5 is made of thermoplastic elastic TPE, and the arc-shaped protrusion 501 and the flexible hyperboloid portion 502 on both sides are integrally formed.

[0041] Furthermore, the massage bump 601 in this embodiment includes: an integrally formed top massage bump 17 and a bottom support bump 18, wherein the bottom support bump 18 is fixedly connected to the arc-shaped protrusion 501 of the TPE elastic substrate 5 by ultrasonic welding.

[0042] Furthermore, in this embodiment, the air pump 1 is fixed to the seat back frame 10 by a clamping bracket, and the clamping bracket is provided with a positioning boss, which cooperates with the groove on the seat back frame 10.

[0043] Furthermore, in this embodiment, the soft massage plate 602 is provided with a surface contact layer 19 for contacting the feet, and the surface contact layer 19 is provided with a number of acupoint massage points.

[0044] Furthermore, in this embodiment, the air bag 3 and the air bag bracket 4 are connected by ultrasonic welding. The top surface of the air bag 3 is fixedly connected to the arc-shaped protrusion 501 by ultrasonic welding. The air bag bracket 4 is provided with buckles around its perimeter for fixing to the roller shutter module 11, and has a recess in the middle for positioning the air bag 3. The edges of the two flexible hyperboloid portions 502 are provided with unequally spaced installation snap points. The unequally spaced installation snap points snap into the corresponding installation points of the air bag bracket 4. The unequally spaced installation snap points are used to prevent errors and to prevent incorrect installation at the left and right ends.

[0045] Working principle: Air pump 1 inflates air bag 3 through air tube 7. The inflation and expansion of air bag 3 drives TPE elastic substrate 5. Under the influence of air bag 3, the arc-shaped protrusion 501 of TPE elastic substrate 5 rises, causing the massage protrusions 601 of soft massage plate 6 to be pushed out. Due to the lever principle of the flexible hyperboloid 502 of TPE elastic substrate 5 and arc-shaped protrusion 501, the small deformation of air bag 3 can be amplified, thereby causing soft massage plate 6 to produce greater deformation. When the user feels the air bag being pushed out, the massage effect of the superimposed protrusions is more significant, improving the comfort of the massage.
