[0047] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0048] like Figures 1 to 19As shown, a novel anti-pinch support S-shaped integrated functional mattress comprises a motor drive device 1, which is movably connected to an anti-pinch arm structure 2; the anti-pinch arm structure 2 is rotatably connected to the edge of the motor drive device 1, and the motor drive device 1 comprises a driving component 101 for controlling the anti-pinch arm structure 2 to realize rotation and lifting, and the driving component 101 is movably connected to the anti-pinch arm structure 2; the anti-pinch arm structure 2 comprises a plurality of coupled movable joints 201, and adjacent movable joints 201 can restrict each other from rotating; when the anti-pinch arm structure 2 is descending, if the movable joint 201 is subjected to a force opposite to the descending direction, the movable joint 201 will rotate in the direction of the force, and drive the adjacent movable joint 201 to rotate under the action of the limiting structure.

[0049] Specifically, in this embodiment, the motor drive device 1 has two independently operable drive components 101, and the number of anti-pinch arm structures 2 is two; one of the anti-pinch arm structures 2 is connected to the side of the motor drive device 1 close to the mattress head, and the other anti-pinch arm structure 2 is connected to the side of the motor drive device 1 close to the mattress leg; the drive components 101 and the anti-pinch arm structures 2 are used in a one-to-one correspondence; therefore, through the structure of these two drive components 101 and the two anti-pinch arm structures 2, the lifting and lowering of the mattress head and the mattress legs can be controlled separately.

[0050] Therefore, in the present technical solution, three solutions are protected: a solution in which only the head of the mattress is lifted and lowered, a solution in which only the legs of the mattress are lifted and lowered, and a solution in which both the head of the mattress and the legs of the mattress have the lifting function.

[0051] There is a limiting structure between adjacent movable joints 201, and the limiting structure includes a first limiting member 2a and a second limiting member 2b; the first limiting member 2a is located at one end of the movable joint 201, and the second limiting member 2b is located at the other end of the movable joint 201; in two adjacently connected movable joints 201, the first limiting member 2a of one movable joint 201 is used in combination with the second limiting member 2b of the other movable joint 201; the second limiting member 2b surrounds a limited movable space 2b3, the first limiting member 2a can rotate in the limited movable space 2b3, and the rotating surface of the first limiting member 2a intersects with the second limiting member 2b. The limiting structure can, on the one hand, enable the adjacent movable joints 201 to maintain a straight lying or raised state, and on the other hand, enable the movable joints 201 to rotate at a certain angle, so as to achieve rolling up, which will be explained in detail below.

[0052] The first limiting member 2a includes a first assembly cylinder 2a1 located in the middle, and the left and right ends of the first assembly cylinder 2a1 are connected with a clamping plate 2a2; the second limiting member 2b includes a second assembly cylinder 2b1 located in the middle, and the second assembly cylinder 2b1 is embedded in the first assembly cylinder 2a1; when adjacent movable joints 201 are connected, the second assembly cylinder 2b1 is embedded in the first assembly cylinder 2a1, and the second assembly cylinder 2b1 and the first assembly cylinder 2a1 are both hollow. At this time, by installing bolts horizontally in the hollow, the adjacent movable joints 1 can be rotated and fixed together.

[0053] The second assembly cylinder 2b1 is provided with a fan-shaped boss 2b2 outside, and the limited activity space 2b3 is sandwiched between the fan-shaped boss 2b2; when two adjacent movable joints 201 rotate relative to each other, the clamping plate 2a2 of one movable joint 201 rotates in the limited activity space 2b3 of the other movable joint 201. When the anti-pinch support arm structure 2 is blocked by external force when rotating downward (i.e., when encountering an obstacle during descent), the first limiting member 2a can rotate in the limited activity space 2b3, and the rotation surface of the first limiting member 2a intersects with the second limiting member 2b, that is, the first limiting member 2a will be limited by the second limiting member 2b after rotating back a certain angle, so that the movable joints 1 connected in sequence can all rotate.

[0054] Combination Figures 6 to 10 It can be seen that blocking side surfaces 2b21 are formed on both sides of the fan-shaped boss 2b2, wherein the blocking side surface 2b21 on one side limits the card plate 2a2 from further rotating clockwise, and wherein the blocking side surface 2b21 on the other side limits the card plate 2a2 from further rotating counterclockwise.

[0055] The purpose of the above restriction is that only by limiting the continued rotation of the card plate 2a2 to one side (limiting the card plate 2a2 from further rotating downward) can the following be formed: Figure 2 as well as Figure 3 The purpose of the whole page lifting is to limit the continued rotation of the card plate 2a2 to the other side (limit the card plate 2a2 from further rotating upwards) to form the following Figure 5 As shown, when one or more active joints 1 encounter an obstacle, a series of reverse rotations will occur, that is, the series of active joints 1 connected have a chain reaction.

[0056] When the movable joint 201 is in a flat state, the card plate 2a2 is set horizontally; the movable joint 201 has a critical edge 2c. When adjacent movable joints 201 are used in combination, the angle between the blocking side 2b21 used to limit the further rotation of the card plate 2a2 and the horizontal line is set to α, and the angle between the critical edge 2c and the horizontal line is set to β, then β>α, and the value range of α is 10~70°; the purpose of the above design is that when the card plate 2a2 is rotated to the angle α, it is limited and will not rotate further, so as to avoid the critical edge 2c being compressed and damaged; the value range of α is 10~70°, which can be set according to actual needs. In this embodiment, α is set to 70°.

[0057] In this embodiment, the number of the fan-shaped boss 2b2 and the card plate 2a2 are both two, and the blocking side 2b21 located above the lower fan-shaped boss 2b2 and the blocking side 2b21 located below the upper fan-shaped boss 2b2 jointly limit the card plate 2a2 to rotate counterclockwise, so that the whole-plate anti-clamping support arm structure is as follows Figure 2 As shown in the figure, it can lie flat and the end can be stressed as Figure 3 The entire page shown is lifted; from Fig.10 It can be seen that the blocking side 2b21 located at the bottom of the lower fan-shaped boss 2b2 and the blocking side 2b21 located at the top of the upper fan-shaped boss 2b2 jointly limit the card plate 2a2 to rotate clockwise, so that when the anti-pinch arm structure is subjected to external force (such as pressing on a child), the connected movable joint 1 will rotate away from the child, and the movable joint 1 is driven to rotate in turn to form a wrapping shape, which will not crush the child.

[0058] The following is an explanation of one of the driving components. The driving component 101 includes a motor 1011, and the motor 1011 is connected to a first screw rod 1012, and the first screw rod 1012 is meshingly connected to a gear 1013; the gear 1013 is coaxially connected to a second screw rod 1014, and the second screw rod 1014 is threadedly connected to a slider 1016; a limiting component 1017 is provided in the motor drive device 1 to limit the slider 1016 to rotate following the second screw rod 1014.

[0059] In this embodiment, the first screw 1012 is a worm, and the gear 1013 is a worm wheel, and the two are combined into a worm gear structure; the second screw 1014 is a lead screw, and a lead screw sleeve is provided in the slider 1016 to match the lead screw. At the same time, because the slider 1016 is limited by the limiting component 1017, the second screw 1014 and the slider 1016 form a lead screw module structure. Therefore, it can be seen from the above structure that the rotation of the motor 1011 drives the second screw 1014 to rotate through the first screw 1012 and the gear 1013, and finally drives the slider 1016 to slide left and right; corresponding Fig.14It can be seen that the movable joint 201 connected to the motor drive device 1 is quite special. A triangular protrusion is formed near the position of the movable joint 201 and the upper part of the movable joint 201 is rotatably connected to the motor drive device 1. The slider 1016 pushes the triangular protrusion so that the movable joint 201 can rotate, so that the anti-pinch arm structure can rotate and rise as a whole; when the slider 1016 slides outward, the anti-pinch arm structure is lifted up to raise the anti-pinch arm structure; when the slider 1016 slides inward and resets, the anti-pinch arm structure is no longer lifted up, so that the anti-pinch arm structure drops and lies flat.

[0060] The end of the second screw rod 1014 is connected to a bearing 1022, and the slider 1016 and the bearing 1022 are respectively distributed on both sides of the gear 1013; the bearing 1022 allows the second screw rod 1014 to be rotatably assembled in the motor drive device 1;

[0061] The second screw rod 1014 includes a main rod section 10141 and an assembly section 10142. The main rod section 10141 has threads and is used in conjunction with the slider 1016. The slider 1016 is connected to the main rod section 10141. A limiting step is provided between the main rod section 10141 and the assembly section 10142. The gear 1013 is inserted from one side of the assembly section 10142 and fixed on one side of the limiting step. The gear 1013 is inserted from one side of the assembly section 10142 and fixed on one side of the limiting step. The limiting step is used to limit the installation of the gear 1013. The side of the gear 1013 is connected to a fastening member 1015, and the fastening member 1015 is connected to the inner ring of the bearing 1022.

[0062] The assembly section 10142 is in the shape of a D-axis, and the mounting hole of the clamping member 1015 matches the D-axis shape; the clamping member 1015 is protrudingly formed with protruding teeth 10151 on all sides, and the corresponding position of the gear 1013 has a recessed position 10131, and the protruding teeth 10151 are embedded in the recessed position 10131; the end of the assembly section 10142 is threadedly connected with a lock nut 1018, and the lock nut 1018 is connected to the inner ring of the bearing 1022.

[0063] Therefore, after the gear 1013 and the locking member 1015 are sequentially inserted into the assembly section 10142 and then the anti-loosening nut 1018 is tightened, the gear 1013 can be fixed tightly, and the locking member 1015 and the anti-loosening nut 1018 are both connected to the inner ring of the bearing 1022, and do not affect the rotation of the outer ring of the bearing 1022, that is, do not affect the rotation of the second screw 1014.

[0064] like Figure 8As shown, the assembly section 10142 is D-shaped, and the mounting hole of the fastening member 1015 matches the D-shaped axis; therefore, when the fastening member 1015 is installed to the position of the D-shaped axis, the effect of limited installation is achieved, that is, the fastening member 1015 will not rotate relative to the assembly section 10142; the fastening member 1015 is protruded around to form a protruding tooth 10151, and the corresponding position of the gear 1013 has a concave position 10131, and the protruding tooth 10151 is embedded in the concave position 10131; combined with Fig.17 as well as Fig.18 Look, this structure, which is embedded and installed through the protruding tooth 10151 and the recessed position 10131, can achieve the purpose of locking the rotation of the gear 1013, so that the gear 1013 will not rotate relative to the assembly section 10142, making the structure stable and non-slip, thereby ensuring that the gear 1013 and the second screw 1014 rotate stably and synchronously, which helps to accurately control the moving position of the slider 1016.

[0065] The limiting component 1017 includes a slide groove formed by the inside of the motor drive device 1. The slide groove is arranged along the length direction of the second screw rod 1014. The longitudinal section shape of the slide groove matches the shape of the slider 1016.

[0066] That is, due to the limitation of the sliding groove, when the second screw rod 1014 rotates, the sliding block 1016 cannot rotate accordingly and can only move back and forth along the length direction of the second screw rod 1014 .

[0067] As another embodiment of the limiting component, the limiting component may be a guide rail along the length direction of the second screw rod 1014 , and the slider 1016 is slidably connected to the guide rail; the guide rail also achieves the purpose of limiting the rotation of the slider 1016 .

[0068] A gap 1019 is reserved below the slide slot, and a first travel sensing switch 1020 and a second travel sensing switch 1021 are arranged below the gap 1019. Both the first sensing switch and the second sensing switch are electrically connected to the motor. A sensing member 10161 extending toward the gap 1019 is arranged on the lower surface of the slider 1016.

[0069] In this embodiment, the first travel sensing switch 1020 and the second travel sensing switch 1021 are both proximity switches. Fig.13 and Fig.14It can be seen that the second stroke sensing switch 1021 is the maximum position for controlling the slider 1016 to slide outward, and the first stroke sensing switch 1020 is the maximum position for controlling the slider 1016 to slide inward. When the slider 1016 is moving, when the sensing element 10161 of the slider 1016 is close to the sensing range of the second stroke sensing switch 1021, the second stroke sensing switch 1021 sends a signal, which is finally transmitted to the motor 1011 to stop; similarly, when the sensing element 10161 of the slider 1016 is close to the sensing range of the first stroke sensing switch 1020, the first stroke sensing switch 1020 sends a signal, which is finally transmitted to the motor 1011 to stop, thereby avoiding excessive movement of the slider 1016 to form damage.

[0070] The motor drive device 1 and the inner side protrusions of the movable joint 201 are provided with a frame installation insertion position 3; the frame installation insertion position 3 is used to insert and install the slat frame. In the actual application of the mattress, two motor drive devices 1 and two anti-pinch arm structures 2 are used (each anti-pinch arm structure 2 includes a mattress head and a mattress leg). The two motor drive devices 1 and the two anti-pinch arm structures 2 are located on the left and right sides of the mattress, and are connected in the middle by the slat frame to form a whole, and then filled with sponge, cotton pads and subsequently wrapped with a bedspread to form the entire finished mattress.

[0071] The most significant feature of the present invention is that the combined use of the first limiting member 2a and the second limiting member 2b allows adjacent movable joints 1 to have a certain angle of rotation limit. When switching from a raised state to a flat state, if there is an obstacle below, especially if the obstacle is an infant, the first limiting member 2a and the second limiting member 2b will rotate relative to each other, so that the movable joints 1 will be rolled up in turn in the opposite direction of the obstacle, thereby avoiding crushing injuries to infants and young children, and also protecting the anti-pinch arm structure itself. In addition, since the mattress is composed of a plurality of movable joints 1, the packaging can be such that the movable joints 1 on both sides of the motor drive device 1 can be folded in half and rolled up to put into a small carton, making it convenient and quick to go up and down the stairs and enter the house.

[0072] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. However, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
