The rotation and vibration of the massage head are combined to improve the comfort and effect of the massage. 3. The design of the ventilation unit can reduce the stuffiness of the user's back in summer. Through the periodic squeezing and stretching of the elastic bladder and the control of the one-way valve, the gas is inhaled and ejected, providing the user with a cool airflow. In addition, the design of the connection component allows the user to easily adjust the ventilation function according to the season and needs. In winter, the elastic bladder can be adjusted to stop supplying air and the ventilation function can be canceled; 4. The installation slot on the flexible rack has a built-in hose, which stores electrorheological fluid. When the massage cushion needs to be shaped, the wire in the hose can be energized to "solidify" the electrorheological fluid and provide additional support. This "solidification" phenomenon is reversible, allowing the flexible rack to deform again, thereby improving the flexibility and adaptability of the massage cushion. 5. The design of the connecting components allows users to adjust the ventilation function and auxiliary shaping function through simple operations. The design of the damping wheel and the damping plate provides greater friction for the rotating rod, preventing the rotating rod from rotating under non-human conditions and ensuring the stability of the position of the rotating rod and the block.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Reference Figure 1-14 A non-hard shell flexible massage cushion comprises an outer layer bag 11, a frame assembly, a massage unit and a ventilation unit. The frame assembly, the massage unit and the ventilation unit are arranged inside the outer layer bag 11. An opening is provided at one end of the outer layer bag 11, and a zipper is provided at the opening position. A plurality of ventilation holes 12 (such as Fig.14As shown), a cover cloth 13 is arranged on the side of the outer bag 11, and the cover cloth 13 is arranged opposite to the plurality of vent holes 12. One side of the cover cloth 13 is fixedly connected to the outer bag 11, and the other three sides of the cover cloth 13 can be connected to the outer bag 11 through Velcro; The frame assembly includes an upper frame 21, a lower frame 22, two flexible racks 23, a conductive strip 24 and a power supply rack 25. The two flexible racks 23 are fixed between the upper frame 21 and the lower frame 22. The upper frame 21, the lower frame 22 and the two flexible racks 23 together form a frame-like structure. The conductive strip 24 is fixed between the upper frame 21 and the lower frame 22. The power supply rack 25 is slidably assembled on the conductive strip 24. The power supply rack 25 can always contact the conductive strip 24 during the movement process to realize continuous power supply to the electronic devices inside the outer shell 31. The flexible rack 23 is provided with a mounting groove 81 (such as Figure 7 As shown, a long hose 82 is fixed inside the mounting groove 81, and an electrorheological fluid is stored inside the hose 82. A wire 83 is arranged inside the hose 82 (as shown in FIG. Fig.12 As shown in the figure, when the flexible rack 23 is deformed, the hose 82 is deformed accordingly. The hose 82 has a built-in wire 83, and electrorheological fluid is accumulated inside the hose 82. The electrorheological fluid is a special liquid that can quickly change its physical state under the action of an electric field. Under normal conditions, the electrorheological fluid is in a flowing state, but when an electric field is applied, it will quickly "solidify" to provide a stable supporting force. When the massage cushion needs to be shaped, the user can control the wires 83 in the two hoses 82 to energize. When the wires 83 are energized, the electric field generated by the wires 83 can cause the electrorheological fluid in the hose 82 to "solidify". As the electrorheological fluid "solidifies", the hose 82 and the flexible rack 23 obtain additional support force, so that they can maintain the current shape. This "solidification" phenomenon is reversible. When the power is disconnected, the electrorheological fluid will restore its flow state, allowing the flexible rack 23 to deform again. For the user, this auxiliary shaping function greatly improves the flexibility and adaptability of the massage cushion. It is worth noting that the circuit connection method and power supply method of the two wires 83 are prior art, which are not shown in the figure and will not be described in detail here. Preferably, the two wires 83 can be connected in series to a battery, and the battery is controlled by a switch. The user can control whether the current flows through the two wires 83 through the switch; The massage unit includes an outer shell 31, a dual-axis motor 32, two moving components, two massage components and two vibration components. The outer shell 31 is slidably assembled on two flexible racks 23. Two avoidance openings are provided on the outer shell 31. The dual-axis motor 32 is installed inside the outer shell 31. The two moving components, two massage components and two vibration components are all arranged inside the outer shell 31. The moving component includes a worm 33, a travel gear 34 and a transmission gear set 35. The worm 33 is fixed on the output shaft of the dual-axis motor 32. The travel gear 34 is rotatably assembled inside the outer shell 31. The travel gear 34 passes through the avoidance opening. The transmission gear set 35 is arranged inside the outer shell 31, and includes a toothed disc in the transmission gear set 35, and the travel gear 34 is fixed to the toothed disc, and the travel gear 34 is coaxially arranged with the toothed disc. The transmission gear set 35 is provided with a worm wheel meshing with the worm 33, and the worm wheel in the transmission gear set 35 is driven to rotate when the worm 33 rotates. The transmission gear set 35 transmits the power of the dual-axis motor 32 to the toothed disc, so that the toothed disc drives the travel gear 34 to rotate, and the travel gear 34 is meshed with the flexible rack 23, so that the travel gear 34 can move along the flexible rack 23 when it rotates; The massage assembly includes a driving gear 41, a rotating shaft 42, a slot 43, a movable rod 44 and a massage head 46. The rotating shaft 42 (such as Fig.11 The drive gear 41 is fixedly mounted on the rotating shaft 42, and the drive gear 41 is meshed with the transmission gear set 35 (as shown in FIG. Figure 3 As shown in the figure, a slot 43 is formed at the top of the rotating shaft 42, and a movable rod 44 is slidably disposed inside the slot 43. The cross-sections of the slot 43 and the movable rod 44 are both rectangular structures. The movable rod 44 is connected to the bottom of the slot 43 through a connecting spring 45. The top of the movable rod 44 extends to the outside of the outer shell 31 and is connected to the massage head 46. The transmission gear set 35 can also transmit the power of the dual-axis motor 32 to the driving gear 41 during operation, so that the driving gear 41 drives the rotating shaft 42 to rotate. Since the cross-sections of the slot 43 and the movable rod 44 are both rectangular structures, Therefore, when the rotating shaft 42 rotates, the movable rod 44 can be driven to rotate, and the massage head 46 connected to the movable rod 44 will also rotate accordingly. Based on the above process, the movement of the outer shell 31 and the rotation of the two massage heads 46 are synchronized. In this process, the two massage heads 46 can massage the back of the user. The vibration assembly includes a rotating block 51, a vibration block 52, a vibration rod 53 and a guide ring 54. The rotating block 51 is fixedly sleeved on the rotating shaft 42, the vibration block 52 is slidably sleeved on the rotating shaft 42, and the vibration rod 53 is fixed on the top surface of the vibration block 52 (such as Figure 6 As shown in FIG. 1 , the top end of the vibration rod 53 extends to the outside of the outer shell 31 and is arranged opposite to the massage head 46. The guide ring 54 is fixed inside the outer shell 31 (as shown in FIG. Fig. 9As shown in the figure, the inner ring of the guide ring 54 is provided with a limiting groove 55, and the outer circumferential surface of the vibration block 52 is fixed with a limiting block 56, and the limiting block 56 is slidably set in the limiting groove 55. The rotating block 51 and the vibration block 52 are arranged vertically opposite to each other, and the rotating block 51 and the vibration block 52 together form a cylindrical structure. The rotating block 51 and the vibration block 52 are of the same size, and the opposite ends of the rotating block 51 and the vibration block 52 are both provided with inclined surfaces. The outer circumferential surface of the vibration block 52 fits with the side surface of the guide ring 54. When the rotating block 51 rotates, the inclined surfaces opposite to the rotating block 51 and the vibration block 52 will push the vibration block 52 to When the rotating block 51 does not apply a thrust to the vibration block 52, the vibration rod 53 no longer applies a thrust to the massage head 46. At this time, the massage head 46 will be reset under the elastic force of the connecting spring 45. Based on the above process, under the cooperation of the rotating block 51 and the vibration block 52, the massage head 46 can produce a vibration effect. The rotation action of the massage head 46 combined with the vibration action can improve the comfort of the user. The ventilation unit includes a ventilation pipe 61, an air supply assembly and a connecting assembly. The ventilation pipe 61 is fixed on the outer shell 31 (such as Fig.10 As shown in the figure, a plurality of air jets 62 are provided on the ventilation pipe 61, the air supply assembly is arranged between the lower frame 22 and the outer shell 31, the connecting assembly is arranged on the lower frame 22, the air supply assembly includes an elastic capsule 63, two frames 64, two air pipes 65, two one-way valves 66 and two guide rods 67, the elastic capsule 63 is a plate-like structure, the two frames 64 are respectively fixed at both ends of the elastic capsule 63, one of the frames 64 is connected to the outer shell 31, and the other frame 64 is connected to the lower frame 22, the two air pipes 65 are connected to the elastic capsule 63, and the two one-way valves 66 are respectively installed on the two air pipes 65 (as shown in the figure). Figure 7As shown in the figure, the flow limiting directions of the two one-way valves 66 are opposite, one of the air pipes 65 is connected to the external environment, and the other air pipe 65 is connected to the ventilation pipe 61 at one end away from the elastic capsule 63, and the two guide rods 67 are fixed between the upper frame 21 and the lower frame 22. Connecting rods 69 are fixed at both ends of the frame 64, and guide sleeves 68 are fixed at one end of the two connecting rods 69 away from the frame 64. The guide sleeves 68 are slidably sleeved on the guide rods 67, and the guide rods 67 are made of flexible material. When the frame 64 moves, the guide sleeves 68 and the guide rods 67 act on the movement of the frame 64. To achieve the limiting effect, during the reciprocating movement of the outer shell 31, the elastic capsule 63 can continuously supply air to the inside of the ventilation pipe 61, so that the gas is ejected through the plurality of air jets 62. At the same time, the user can flip the cover cloth 13 on the outer bag 11 to separate the cover cloth 13 from the outer bag 11 and expose the plurality of air holes 12. In this case, the airflow ejected from the plurality of air jets 62 can be ejected through the plurality of air holes 12 and blow toward the user's back. This design can reduce the stuffiness generated by the user when using the massage cushion in summer, and further improve the user's comfort. The connecting assembly is composed of a fixing portion and a connecting portion; the fixing portion includes a fixing cylinder 71, a positioning cylinder 72 and a slot 73, the fixing cylinder 71 is fixed to the side of the frame 64 near the lower frame 22 (such as Figure 8 As shown, the positioning cylinder 72 is fixed inside the fixing cylinder 71, and the card slot 73 is provided on the inner circle of the positioning cylinder 72; the connecting portion includes a fixing seat 74, a rotating rod 75 and a card block 76, the fixing seat 74 is fixed to the side of the lower frame 22, and the rotating rod 75 is rotatably assembled on the fixing seat 74 (as shown in FIG. Fig.13The cam 76 is fixed to one end of the rotating rod 75, and a knob is fixed to the other end of the rotating rod 75. The shape of the cam 76 matches the slot 73. Two positioning protrusions 77 are fixed to the side of the fixing seat 74. A positioning rod 78 is fixed to the rotating rod 75. The positioning rod 78 is arranged between the two positioning protrusions 77. A damping wheel 79 is fixedly sleeved on the rotating rod 75. A damping plate 710 is fixed to the lower frame 22. The damping wheel 79 and the damping plate 710 fit each other. In winter, the ventilation function of the massage cushion may not be needed. At this time, the staff can adjust the connecting assembly to separate the frame 64 close to the lower frame 22 from the lower frame 22. When the two are separated, the movement of the outer shell 31 will directly drive the elastic capsule 63 to move. In this process, the elastic capsule 63 The elastic sac 63 will not be stretched or compressed, and the air supply action will stop accordingly. Specifically, when it is necessary to release the connection between the frame 64 and the lower frame 22, the user opens the zipper on the outer bag 11 to open the outer bag 11, and then manually turns the knob to drive the rotating rod 75 to rotate. When the rotating rod 75 rotates, the block 76 thereon rotates accordingly. The user rotates the rotating rod 75 until the block 76 is aligned with the slot 73. In this case, the block 76 no longer provides a limit for the positioning tube 72. When the outer shell 31 pulls the elastic sac 63, the positioning tube 72 will directly separate from the rotating rod 75, that is, the outer shell 31 will pull the entire elastic sac 63 to move. In this case, the elastic sac 63 no longer performs an air supply action, and the ventilation function is cancelled.

[0021] The specific working principle of the present invention is as follows: The main frame of a multi-angle chip defect detection device proposed by the present invention is composed of an upper frame 21, a lower frame 22 and two flexible racks 23. The outer bag 11 is sleeved on the main frame to form an outer layer protection of the main frame. The upper frame 21 and the lower frame 22 respectively resist the two ends of the outer bag 11 to provide support for the outer bag 11. The two flexible racks 23 are made of flexible materials, such as soft plastic or rubber materials. When massaging, the outer shell 31 moves along the two flexible racks 23, and the two massage heads 46 on the outer shell 31 massage the user's back. This structural form replaces the traditional structure of the massage cushion with a hard shell, and the overall structure is lighter and thinner. It not only reduces the space occupied, but also improves the aesthetics of the product. The unique flexible rack 23 design can produce deformation to adapt to different shapes. This feature ensures that the cushion can better fit the human body curve. At the position where the human body contacts, due to the optimization of the structure and the softness of the material, the user can hardly feel any foreign body sensation, which greatly enhances the comfort of use. In addition, due to the reduction in thickness, the body sensation when sitting is more natural, and the comfort of massage is also significantly improved. In general, the "shellless flexible cushion" massage component has achieved multiple advantages such as lightness, strong adaptability, low foreign body sensation and good massage comfort through its innovative design, bringing users a better massage experience; For the massage unit, the operation of the massage unit is powered by a dual-axis motor 32. Specifically, when the dual-axis motor 32 is running, it drives the two worm gears 33 to rotate. When the worm gear 33 rotates, it drives the worm wheel in the transmission gear set 35 to rotate. The transmission gear set 35 transmits the power of the dual-axis motor 32 to the toothed disc, so that the toothed disc drives the traveling gear 34 to rotate. The traveling gear 34 is meshed with the flexible rack 23. Therefore, when the traveling gear 34 rotates, it can move along the flexible rack 23. In summary, when the dual-axis motor 32 is running, the two traveling gears 34 rotate synchronously and jointly drive the outer shell 31 to move along the two flexible racks 23. It should be noted that when the outer shell 31 moves to the end position of the flexible rack 23, the dual-axis motor 32 is reversed. The outer shell 31 is moved back and forth between the upper frame 21 and the lower frame 22. Furthermore, the transmission gear set 35 can also transmit the power of the dual-axis motor 32 to the driving gear 41 during operation, so that the driving gear 41 drives the rotating shaft 42 to rotate. Since the cross-sections of the slot 43 and the movable rod 44 are both rectangular structures, the rotating shaft 42 can drive the movable rod 44 to rotate, and the massage head 46 connected to the movable rod 44 will also rotate accordingly. Based on the above process, the movement of the outer shell 31 and the rotation of the two massage heads 46 are performed synchronously. In this process, the two massage heads 46 can massage the back of the user. As for the rotating shaft 42, when the rotating shaft 42 rotates, it can also drive the rotating block 51 thereon to rotate. Since the rotating block 51 and the vibrating block 52 are arranged vertically opposite to each other, the rotating block 51 and the vibrating block 52 together form a cylindrical structure. The rotating block 51 and the vibrating block 52 are of the same size. The opposite ends of the rotating block 51 and the vibrating block 52 are both provided with inclined surfaces. A limiting block 56 is connected to the vibrating block 52, and the limiting block 56 is slidably arranged in the limiting groove 55. Under the limiting action of the limiting block 56 and the limiting groove 55, the vibrating block 52 can only move in the vertical direction. The rotating block 51 will continuously squeeze the vibrating block 52 during the rotation process. When the moving block 51 pushes the vibration block 52 upward, the vibration block 52 will move upward and drive the vibration rod 53 to move upward. When the vibration rod 53 moves upward, it can push the massage head 46, so that the massage head 46 moves in a direction away from the outer shell 31. When the rotating block 51 does not apply a thrust to the vibration block 52, the vibration rod 53 no longer applies a thrust to the massage head 46. At this time, the massage head 46 will be reset under the elastic force of the connecting spring 45. Based on the above process, under the cooperation of the rotating block 51 and the vibration block 52, the massage head 46 can produce a vibration effect. The rotation action of the massage head 46 combined with the vibration action can improve the comfort of the user. In the present invention, a ventilation unit is further provided on the outer shell 31. In summer, the airflow generated by the ventilation unit can reduce the stuffiness generated on the user's back and further improve the user's comfort. Specifically, when the outer shell 31 moves back and forth between the upper frame 21 and the lower frame 22, it will periodically squeeze and stretch the elastic sac 63. Two air pipes 65 are connected to the elastic sac 63. Both air pipes 65 are equipped with one-way valves 66, and the flow limiting directions of the two one-way valves 66 are opposite. Specifically, one of the one-way valves 66 limits the gas to only enter the elastic sac 63, and the other one-way valve 66 limits the gas to only flow out of the elastic sac 63. When the elastic sac 63 is stretched, the elastic sac 63 can be evacuated through one of the air pipes 65. When When the elastic sac 63 is squeezed, the elastic sac 63 can press the internal gas into the ventilation pipe 61 through another air pipe 65, so that the gas is ejected through the plurality of jet ports 62 on the ventilation pipe 61. In summary, during the reciprocating movement of the outer shell 31, the elastic sac 63 can continuously supply gas to the inside of the ventilation pipe 61, so that the gas is ejected through the plurality of jet ports 62. At the same time, the user can flip the cover cloth 13 on the outer bag 11 to separate the cover cloth 13 from the outer bag 11 and expose the plurality of air holes 12. In this case, the airflow ejected from the plurality of air holes 62 can be ejected through the plurality of air holes 12 and blow toward the user's back. This design can reduce the stuffiness generated by the user when using the massage cushion in summer, and further improve the user's comfort. In winter, the ventilation function of the massage cushion may not be needed. At this time, the staff can adjust the connection component to separate the frame 64 close to the lower frame 22 from the lower frame 22. When the two are separated, the movement of the outer shell 31 will directly drive the elastic capsule 63 to move. During this process, the elastic capsule 63 will not be stretched or compressed, and the air supply action will also stop. Specifically, when it is necessary to release the connection between the frame 64 and the lower frame 22, the user opens the zipper on the outer bag 11 to open the outer bag 11. , and then manually turn the knob to make the knob drive the rotating rod 75 to rotate. When the rotating rod 75 rotates, the block 76 thereon rotates accordingly. The user rotates the rotating rod 75 until the block 76 is aligned with the card slot 73. In this case, the block 76 no longer provides a limit for the positioning cylinder 72. When the outer shell 31 pulls the elastic capsule 63, the positioning cylinder 72 will directly separate from the rotating rod 75, that is, the outer shell 31 will pull the entire elastic capsule 63 to move. In this case, the elastic capsule 63 no longer performs the air supply action, and the ventilation function is cancelled; When the ventilation function needs to be restored, the user can also use the connecting assembly to connect the lower frame 22 with the frame 64. Specifically, the user first pulls the frame 64 close to the lower frame 22 so that the positioning cylinder 72 is sleeved on the rotating rod 75 and the block 76 passes through the slot 73. Then the user turns the knob to make the rotating rod 75 drive the block 76 to rotate until the block 76 is separated from the slot 73. At this time, the block 76 can limit the positioning cylinder 72, that is, the positioning cylinder 72 is blocked by the block 76 and cannot move. In this case, the movement of the outer shell 31 will stretch or squeeze the elastic capsule 63, and the ventilation function will be restored. It is worth mentioning that two positioning protrusions 77 are provided on the fixing seat 74, and a positioning rod 78 is fixed on the rotating rod 75, and the positioning rod 78 is located between the two positioning protrusions 77. The two positioning protrusions 77 play a positioning role on the positioning rod 78. When one positioning protrusion 77 contacts, the card block 76 and the card slot 73 are in a state of mutual displacement. When the positioning rod 78 contacts the other positioning protrusion 77, the card block 76 and the card slot 73 are in a state of mutual alignment. Therefore, when the user adjusts the position of the card block 76, the two positioning protrusions 77 and the positioning rod 78 can be used to accurately adjust the rotation angle of the rotating rod 75. Secondly, a damping wheel 79 is fixedly sleeved on the rotating rod 75, and a damping plate 710 is fixed on the lower frame 22. The damping plate 710 is provided with a concave surface adapted to the damping wheel 79. The damping wheel 79 and the damping plate 710 fit each other, and the damping wheel 79 and the damping plate 710 are both made of rubber material. The damping wheel 79 and the damping plate 710 can provide a large friction force for the rotating rod 75. The friction force can prevent the rotating rod 75 from rotating in non-human conditions, thereby ensuring the stability of the position of the rotating rod 75 and the card block 76. In addition, the massage cushion proposed by the present invention also has the function of assisting shaping. Specifically, the flexible rack 23 is provided with a mounting groove 81 along its length direction. The mounting groove 81 has a built-in hose 82. The hose 82 stores electrorheological fluid. When the flexible rack 23 is deformed, the hose 82 is deformed accordingly. The hose 82 has a built-in wire 83, and the hose 82 stores electrorheological fluid. The electrorheological fluid is a special liquid that can rapidly change its physical state under the action of an electric field. Under normal conditions, the electrorheological fluid is in a flowing state, but when an electric field is applied, it will rapidly "solidify" to provide a stable supporting force. When the massage cushion needs to be shaped, the user can control the wires 83 in the two hoses 82 to energize. When the wires 83 When power is turned on, the electric field generated by the wire 83 can cause the electrorheological fluid in the hose 82 to "solidify". As the electrorheological fluid "solidifies", the hose 82 and the flexible rack 23 obtain additional supporting force, thereby being able to maintain the current shape. This "solidification" phenomenon is reversible. When the power is disconnected, the electrorheological fluid will resume its flow state, allowing the flexible rack 23 to deform again. For users, this auxiliary shaping function greatly enhances the flexibility and adaptability of the massage cushion. They can adjust the shape of the cushion according to their needs and easily fix it when needed. In addition, since the "solidification" phenomenon of the electrorheological fluid is reversible, users can also change the shape of the cushion at any time to adapt to different massage needs.
