Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] The purpose of this invention is to provide a mechanical massager for car seats, a car seat massage system, and a car seat, so as to solve the problems existing in the prior art, achieve a more stable and powerful massage to the passenger, and improve the massage effect.

[0019] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Example 1 like Figures 1 to 6 As shown, this embodiment provides a mechanical massager for a car seat, including an upper housing 1, a lower housing 2, a power unit 3, and a rotating massage device 4. The upper housing 1 is placed inside the lower housing 2 and can move along the lower housing 2 in a first direction or a second direction. The first direction is towards the occupant, and the second direction is opposite to the first direction. The lower housing 2 and the upper housing 1 can form an inflatable cavity, which is used to communicate with a pneumatic device 14 to provide power for the upper housing 1 to move along the lower housing 2 in the first direction. The power unit 3 is fixedly mounted on the upper housing 1, and the power output shaft of the power unit 3 is fixedly connected to the rotating massage device 4. The power output shaft of the power unit 3 can drive the rotating massage device 4 to rotate.

[0021] The car seat mechanical massager provided in this embodiment drives the rotary massage device 4 to rotate via the power output shaft of the power unit 3, enabling the rotary massage device 4 to perform rotary massage. By filling the inflation cavity with high-pressure gas, the upper shell 1 rises, bringing the rotary massage device 4 closer to the occupant. This allows the car seat mechanical massager to switch between working and retracted states, and to retract into a safer and more reliable state when the occupant does not need a massage. It provides massage function while maintaining good comfort when the occupant does not require a massage. Furthermore, by changing the pressure and flow rate of the high-pressure gas filling the inflation cavity between the upper shell 1 and the lower shell 2, the distance between the rotary massage device 4 and the occupant can be adaptively changed within a certain range, better adapting to the occupant's body surface and achieving a more comfortable massage effect. At the same time, the height of the protrusion of the rotary massage device 4 can be adapted to different people, thus achieving a better massage effect for different occupants. In addition, by making holes in the seat foam 16 inside the seat cover 15, the rotary massage device 4 can pass through to perform massage.

[0022] In a preferred embodiment of this invention, the inner wall of the lower housing 2 is provided with a plurality of guide limiting grooves 5, and the outer wall of the upper housing 1 is provided with a plurality of protrusions 6. The number of protrusions 6 is equal to the number of guide limiting grooves 5. The protrusions 6 correspond one-to-one with the guide limiting grooves 5. The protrusions 6 can extend into the guide limiting grooves 5 and are in sealed contact with the guide limiting grooves 5. The protrusions 6 can move along the guide limiting grooves 5 in a first direction or a second direction, so that the upper housing 1 and the rotating massage device 4 can move stably in the first direction or the second direction.

[0023] In a preferred embodiment of this invention, a first guide groove 7 is provided on the inner sidewall of the lower housing 2, which is perpendicular to the guide limiting groove 5. A second guide groove 8 is provided on the top surface of the lower housing 2, which is parallel to the guide limiting groove 5. The first guide groove 7 corresponds one-to-one with the guide limiting groove 5, and the first guide groove 7 corresponds one-to-one with the second guide groove 8. One end of the first guide groove 7 is connected to the guide limiting groove 5, and the other end of the first guide groove 7 is connected to the second guide groove 8. The protrusion 6 can extend into the second guide groove 8 or the first guide groove 7. The protrusion 6 can move along the second guide groove 8 and enter the first guide groove 7. The protrusion 6 can move along the first guide groove 7 and enter the guide limiting groove 5. This not only restricts the movement of the upper housing 1 in the first or second direction through the guide limiting groove 5, but also facilitates the installation of the upper housing 1 into the lower housing 2.

[0024] As a preferred embodiment of this invention, the center line of the power output shaft of the power unit 3, the center line of the rotary massage device 4, the center line of the upper housing 1, and the center line of the lower housing 2 coincide, which facilitates use.

[0025] As a preferred embodiment of this invention, the top surface of the rotary massage device 4 has at least one massage protrusion 9 that is offset from the center line of the rotary massage device 4, so as to facilitate massage of the occupant.

[0026] In a preferred embodiment of this invention, the power device 3 is an electric motor; a connector 10 is fixedly provided at the bottom of the lower housing 2, and the connector 10 is electrically connected to the power device 3 through a wire. The connector 10 can be connected to an external controller 13 to facilitate the control of the power device 3; a quick-connect air pipe 11 is fixedly provided at the bottom of the lower housing 2, one end of the quick-connect air pipe 11 can be connected to the inflation cavity, and the other end of the quick-connect air pipe 11 is used to connect to the pneumatic device 14 through an air pipe, which facilitates assembly and maintenance.

[0027] In a preferred embodiment of this invention, the upper housing 1 is made of rubber to facilitate sealing; the rotating massage device 4 is made of hard plastic to facilitate use.

[0028] Example 2 like Figures 7 to 8 As shown, this embodiment provides a car seat massage system, including a fixed bracket 12, a controller 13, a pneumatic device 14, and several car seat mechanical massagers as described in Embodiment 1. The pneumatic device 14 can supply air to all the inflatable cavities. The controller 13 and the car seat mechanical massagers are all fixedly mounted on the fixed bracket 12. The controller 13 is communicatively connected to the pneumatic device 14 and the power device 3, and the controller 13 can control the operation of the pneumatic device 14 and the power device 3.

[0029] The car seat massage system provided in this embodiment drives the rotary massage device 4 to rotate via the power output shaft of the power unit 3, enabling the rotary massage device 4 to perform rotary massage. By filling the inflation cavity with high-pressure gas, the upper shell 1 rises, bringing the rotary massage device 4 closer to the passenger. This not only allows the car seat mechanical massager to switch between working and retracted states, but also enables it to retract into a safer and more reliable state when the passenger does not need a massage. It provides massage functionality while maintaining good comfort when the passenger does not require a massage. Furthermore, by changing the pressure and flow rate of the high-pressure gas filling the inflation cavity between the upper shell 1 and the lower shell 2, the distance between the rotary massage device 4 and the passenger can be adaptively changed within a certain range, better adapting to the passenger's body surface and achieving a more comfortable massage effect. At the same time, the height of the protrusion of the rotary massage device 4 can be adapted to different people, thus achieving a better massage effect for different passengers. In addition, by cutting holes in the seat foam 16 inside the seat cover 15, the rotary massage device 4 can pass through to perform massage.

[0030] As a preferred embodiment of this invention, the pneumatic device 14 is an air pump, which is easy to manufacture and use.

[0031] As a preferred embodiment of this invention, the number of car seat mechanical massagers is four, arranged in two rows and two columns, which facilitates manufacturing and use.

[0032] Example 3 This embodiment provides a car seat, including the car seat massage system in Embodiment 2.

[0033] The car seat provided in this embodiment uses the power output shaft of the power unit 3 to drive the rotary massage device 4 to rotate, enabling the rotary massage device 4 to perform rotary massage. By filling the inflation cavity with high-pressure gas, the upper shell 1 rises, bringing the rotary massage device 4 closer to the occupant. This not only allows the car seat mechanical massager to switch between working and retracted states, but also enables it to retract into a safer and more reliable state when the occupant does not need massage. While providing massage function, the seat still maintains good comfort when the occupant does not need massage. Furthermore, by changing the pressure and flow rate of the high-pressure gas filling the inflation cavity between the upper shell 1 and the lower shell 2, the distance between the rotary massage device 4 and the occupant can be adaptively changed within a certain range, better adapting to the occupant's body surface and achieving a more comfortable massage effect. At the same time, the height of the protrusion of the rotary massage device 4 can be adapted to different people, thus achieving a better massage effect for different occupants. In addition, by making holes in the seat foam 16 inside the seat cover 15, the rotary massage device 4 can pass through to perform massage.
