The drive component includes a base, a movable seat, and a drive motor. The massage component is connected to the movable seat through the linkage component. When the movable seat is raised or lowered, the massage component works. The collapse component includes a locking spring and a clamping block. The upper end of the clamping block rotates at the upper limit of the base, and the lower end is fixedly connected to one end of the locking spring. The two clamping blocks are distributed in a figure-eight shape. The fixed end of the drive motor is fixedly connected to the base, and the output end is fixedly provided with a movable block. The movable block is located between the upper ends of the two clamping blocks, and the bottom end of the movable block abuts against the clamping block. When the movable block moves downward, the included angle between the clamping blocks increases.

[0006] In some implementations, the collapse assembly includes a thrust plate positioned above the movable block.

[0007] In some embodiments, the drive assembly includes a reset elastic element disposed between the movable seat and the base.

[0008] In some embodiments, the clamping block has a connecting step on the side near the movable block that abuts against the bottom of the movable block, the width of the movable block is less than the distance between the upper ends of the two clamping blocks, and the width of the movable block is greater than the distance between the two connecting steps.

[0009] In some embodiments, two sets of massage components are respectively disposed on both sides of the drive component. The massage component includes a first massage rod and a second massage rod. The first massage rod and the second massage rod are rotatably connected at one end, and the two first massage rods are connected by a connecting rod.

[0010] In some embodiments, the linkage assembly includes a linkage seat, a first connecting rod, and a second connecting rod. The linkage seat is fixedly disposed on one side of the movable seat.

[0021] Please see Figure 1 This utility model provides a technical solution: an anti-crushing seat massage mechanism, including a massage component 1, a linkage component 2, a drive component 3, and a collapse component 4. Two sets of massage components 1 and linkage components 2 are respectively arranged on both sides of the drive component 3, and the linkage component 2 is used to connect the massage component 1 and the drive component 3.

[0022] Please see Figure 1 and Figure 2 The drive assembly 3 includes a base 31, a movable seat 32, a drive motor 33, and a reset elastic element 34. The base 31 is fixedly connected to the seat frame. The movable seat 32 moves up and down at the upper limit of the base 31. The drive motor 33 is mounted on the movable seat 32. The fixed end of the drive motor 33 is fixedly connected to the movable seat 32, and the output end is fixedly provided with a movable block 35. A reset elastic element 34 is provided between the lower end of the movable seat 32 and the base 31. When the movable seat 32 compresses the reset elastic element 34 downward, the reset elastic element 34 applies an upward elastic force to the movable seat 32.

[0023] The massage assembly 1 includes a first massage head 11, a second massage head 12, a first massage rod 13, and a second massage rod 14. The first massage rod 13 and the second massage rod 14 are rotatably connected at one end. The first massage head 11 is fixedly mounted at one end of the first massage rod 13, and the second massage head 12 is fixedly mounted at the other end of the second massage rod 14. The first massage rods 13 on both sides of the drive assembly 3 are connected by a connecting rod 15. The first massage rod 13 and the connecting rod 15 are rotatably connected, and the connecting rod 15 is fixedly connected to the seat frame (not shown in the attached figure). The connection positions between the first massage rod 13 and the connecting rod 15, and the second massage rod 14, are located at different positions on the first massage rod 13. A return spring is provided at the connection position between the first massage rod 13 and the second massage rod 14.

[0024] Please see Figure 3 and Figure 4 The linkage component 2 includes a linkage seat 21, a first connecting rod 22, and a second connecting rod 23. The linkage seat 21 is fixedly mounted on one side of the movable seat 32. One end of the first connecting rod 22 is connected to the linkage seat 21, and the other end is fixedly provided with a first limiting ball. The two ends of the second connecting rod 23 are respectively fixedly provided with a second limiting ball and a movable limiting ball. The first massage rod 13 is provided with a first limiting groove, within which the first limiting ball is limited to rotate. The second massage rod 14 is provided with a second limiting groove, within which the second limiting ball is limited to rotate. The movable seat 32 is provided with a movable limiting groove, within which the movable limiting ball is limited to rotate. The position of the first limiting ball is higher than the position of the linkage seat 21, and the position of the second limiting ball is higher than the position of the movable limiting ball.

[0025] Please see Figure 2 and Figure 3The collapsible assembly 4 includes a fixed plate 41, a locking spring 42, a clamping block 43, and a thrust plate 44. The collapsible assembly 4 is located above the movable seat 32. The fixed plate 41 is fixedly connected to the base 31. The upper end of the clamping block 43 is rotated at the upper limit on the fixed plate 41 through a connecting column, and the lower end is fixedly connected to one end of the locking spring 42 through a spring hanging point. The two clamping blocks 43 are distributed in a figure-eight shape. The two ends of the locking spring 42 are fixedly connected to the lower ends of the clamping blocks 43 respectively. The movable block 35 is located between the two clamping blocks 43. The side of the clamping block 43 near the movable block 35 is provided with a connecting step 45 that abuts against the bottom end of the movable block 35. The width of the movable block 35 is less than the distance between the upper ends of the two clamping blocks 43 but greater than the distance between the two connecting steps 45. To limit the excessive upward movement of the movable block 35, a thrust plate 44 is provided between the upper ends of the two clamping blocks 43. The thrust plate 44 is L-shaped and is fixedly connected to the fixed plate 41 via a connecting post. One side of the thrust plate 44 is positioned above the movable block 35. When the movable block 35 moves downward, it pushes open the connecting step 45, thereby forcing the lower ends of the two clamping blocks 43 to open away from the movable block 35, increasing the angle between the two clamping blocks 43. Simultaneously, the lower ends of the clamping blocks 43 are subjected to the tension of the locking spring 42. Since the downward movement of the movable block 35 is countered by the tension exerted by the locking spring 42, the downward force on the movable block 35 is insufficient to counteract the tension exerted by the locking spring 42, and the movable block 35 cannot move downward.

[0026] Working principle and usage process of this utility model:

[0027] Normal massage process: The drive motor 33 works. Since the output force of the drive motor 33 is insufficient to counteract the resistance of the locking spring 42, the output end of the drive motor 33 maintains the contact relationship with the connecting step 45. The fixed end of the drive motor 33 drives the movable seat 32 to rise and fall. When the movable seat 32 moves downward against the elastic force of the reset elastic element 34, it drives the linkage seat 21 and the movable limiting groove to move downward. Through the linkage of the first connecting rod 22, the first massage rod 13 rotates, and the first massage head 11 moves closer to the drive assembly 3. Through the linkage of the second connecting rod 23, the angle between the second connecting rod 23 and the second massage rod 14 decreases, and the second massage head 12 moves closer to the drive assembly 3. The angle between the first massage rod 13 and the second massage rod 14 increases. When the movable seat 32 rises under the elastic force of the reset elastic element 34, it drives the linkage seat 21 and the movable limiting groove to rise. Through the linkage of the first connecting rod 22, the first massage rod 13 rotates, and the first massage head 11 moves away from the drive assembly 3. Through the linkage of the second connecting rod 23, the angle between the second connecting rod 23 and the second massage rod 14 increases, and the second massage head 12 moves away from the drive assembly 3. The angle between the first massage rod 13 and the second massage rod 14 decreases.

[0028] When subjected to external impact: When the first massage head 11 and the second massage head 12 are subjected to external force, the angle between the first massage rod 13 and the second massage rod 14 increases. Through the linkage component 2, the movable seat 32 moves downward against the elastic force of the reset elastic element 34, the drive motor 33 moves downward as a whole, the movable block 35 moves downward, the movable block 35 squeezes open the connecting step 45, forcing the lower ends of the two clamping blocks 43 to open away from the movable block 35. At the same time, the lower ends of the clamping blocks 43 are pulled by the locking spring 42, and the drive motor 33 is collapsed. The collapse component 4 buffers the impact of the external force and protects the structure of the drive motor 33. When the external force is removed, the movable seat 32 and the drive motor 33 are reset due to the elastic force of the reset spring element, and the first massage head 11 and the second massage head 12 are also reset.
