Description

Technical Field

[0001] The present application relates to the technical field of support cushion positioning, and in particular to an electric bed, a support cushion positioning structure and a method of using the same. Background Art

[0002] An electric bed is a device that can electrically control the lifting of at least a portion of the bed frame, so that the height of the head, foot or other parts of the bed board can be changed, thereby achieving a change in the degree of bending of the bed board. Electric beds can be widely used in different scenarios such as daily life and hospital care to meet user needs and improve user comfort.

[0003] During the process of raising the bed frame, the mattress may slip, so existing electric beds often have a bracket protruding from the bed surface at the foot of the bed to prevent the mattress from sliding backward. However, this foot bracket makes the user feel uncomfortable when getting in and out of bed, and even if this bracket is provided, the mattress is still easy to fall out when it exceeds the height of the bracket.

[0004] At the same time, when the bed frame is raised, the bracket at the foot cannot ensure the fit between the mattress and the bed frame, and the middle of the mattress is prone to arching. In addition, when the bed frame is raised, the downward sliding movement of the mattress will cause a strong compression on the bracket at the foot position, which will cause the mattress to deform and affect the life of the mattress.

DETAILED DESCRIPTION

[0080] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present application and are not used to limit the present application. In the present application, unless otherwise stated, the directional words used, such as "up", "down", "left", and "right", generally refer to the up, down, left, and right of the device in actual use or working state, specifically the drawing direction in the accompanying drawings.

[0081] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

[0082] The present application provides an electric bed, a support cushion positioning structure and a method of using the same, which are described in detail below. It should be noted that the description order of the following embodiments does not limit the preferred order of the embodiments of the present application. In the following embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, please refer to the relevant description of other embodiments.

[0083] The embodiment of the present application provides an electric bed, see Figure 1 , which includes a bed frame 100 and a mattress 200. Exemplarily, the bed frame 100 has a first side 150 and a second side 160 opposite to each other. Usually, the first side 150 is the upper side and the second side 160 is the lower side. The mattress 200 is arranged on the first side 150 of the bed frame 100, that is, the mattress 200 is arranged on the bed frame 100.

[0084] Please combine Figure 2 The bed frame 100 can be generally arranged on a bottom support member 300, and the bottom support member 300 can include bed legs, etc., which is well known to those skilled in the art. It can be understood that the bottom support member 300 in the drawings of the present application is only an example, and does not constitute an improper limitation to the present application.

[0085] Here, the electric bed also includes a driving member (not shown), which may be a driving motor, an electric cylinder, a pneumatic cylinder, etc. The driving member is connected to the bed frame 100, and can drive at least a portion of the bed frame 100 to lift. The specific location and number of the driving member can be set according to actual needs. Electric beds basically include driving members such as a motor for driving the bed frame to lift, which is well known to those skilled in the art and can be designed according to actual needs. The driving member is not improved in this embodiment, so it will not be described in detail.

[0086] For example, please refer to Figure 2Here, the bed frame 100 includes a first bed frame 110, a second bed frame 120, a third bed frame 130 and a fourth bed frame 140 which are hinged in sequence. When the user lies on the electric bed, the first bed frame 110 roughly corresponds to the position of the user's head and back, the second bed frame 120 roughly corresponds to the position of the user's buttocks, and can also be called a buttocks bed frame, the third bed frame 130 roughly corresponds to the position of the user's thigh, and the fourth bed frame 140 roughly corresponds to the position of the user's calf and foot. Two driving members are respectively connected to the first bed frame 110 and the third bed frame 130. Through the driving of the driving member, the first bed frame 110 and the third bed frame 130 can be driven to lift up, thereby adjusting the posture of the bed frame 100. Here, since the fourth bed frame 140 is hinged to the third bed frame 130, the fourth bed frame 140 is also driven by the third bed frame; or, a driving member can be set to drive the fourth bed frame 140 to rise, etc. It is understandable that the arrangement of the bed frame 100 and the driving member is not limited to the above, and the bed frame 100 may also be in other forms, for example, having only three parts, namely, the first bed frame 110, the second bed frame 120 and the third bed frame 130, or other more or fewer parts; the matching connection between the driving member and the bed frame 100 may also be different, for example, only one driving member connected to any part of the bed frame 100 is provided and can drive the part to lift; this is achievable for those skilled in the art, and the examples in this embodiment do not constitute an improper limitation on the present application.

[0087] For example, Figure 2 That is, it shows a state of the mattress 200 after being lifted. It can be understood that it is only an example and does not constitute an undue limitation to the present application. In some embodiments, after the bed frame 100 is lifted, the bed frame 100 and the mattress 200 may also be in other inclined states.

[0088] Here, when the bed frame 100 is lifted, the mattress 200 on the bed frame 100 will be lifted synchronously, and then the mattress 200 will be lifted to an inclined state. Due to the effect of gravity, the mattress 200 will slide downward, and the relative position between the mattress 200 and the bed frame 100 will change, thereby causing a part of the mattress 200 to bulge or the mattress 200 to fall out of the bed frame 100.

[0089] For this purpose, in the embodiments of the present application, please refer to Figure 3 , at least one channel 170 is provided on the bed frame 100. For example, two channels 170 are provided on the second bed frame 100 and the fourth bed frame 100, respectively. Of course, it can be understood that in other embodiments, the location and number of the channels 170 are not limited to the above. For example, one, two, three, five, six, etc. channels 170 may be provided, and the examples in this embodiment do not constitute an improper limitation thereto.

[0090] Please combine again Figure 4, where the channel 170 passes through the first side 150 and the second side 160 of the bed frame 100. Figure 5-7 And focus on the Figure 6 and Figure 7 , a fastener 400 is further provided on the second side 160 of the bed frame 100, and a connector 500 is provided on the mattress 200, and the connector 500 is provided with a matching portion 600. The connector 500 can pass through the channel 170 on the bed frame 100 to extend from the first side 150 to the second side 160 of the bed frame 100, and the matching portion 600 can be matched with the fastener 400 located on the second side 160 of the bed frame 100, so that the mattress 200 can be better fitted to the bed frame 100.

[0091] Thus, through the cooperation of the matching portion 600 and the fastener 400, the connector 500 and the mattress 200 are constrained, and the mattress 200 is not easy to slip relative to the bed frame 100. In particular, when the bed frame 100 is lifted, the slippage of the mattress 200 relative to the bed frame 100 can be reduced. Furthermore, since the displacement of the mattress 200 is reduced, the fit between the mattress 200 and the bed frame 100 is higher, and the mattress 200 is not easy to bulge or slip out of the bed frame 100, which helps to improve the user's comfort, and also helps to reduce damage to the mattress 200 and increase the service life of the mattress 200.

[0092] In some embodiments, when installing, the user first passes the connector 500 through the channel 170, and the user's hand can be located on the second side 160 of the bed frame 100 and apply force to the connector 500 from the second side 160, so that the matching portion 600 can be matched with the fastener 400, and the second side 160 can be the side of the bed frame 100 close to the ground. After the matching is completed, the connector 500 abuts against the inner wall of the channel 170 to reduce the displacement of the mattress 200 relative to the bed frame 100. Exemplarily, the connector 500 has a free end, and the free end is provided with a stretching portion 510, and the stretching portion 510 is used for the user to hold and operate and stretch the connector 500. Exemplarily, the connector 500 may also have a fixed end, which is the connecting end of the connector 500 and the mattress 200.

[0093] In the embodiment of the present application, the connecting member 500 extends from the first side 150 to the second side 160 of the bed frame 100 through the channel 170, so that the matching portion 600 can match with the fastener 400 on the second side 160 of the bed frame 100. Figure 8 and Fig. 9, which shows a schematic diagram of the bed frame 100 on the second side 160. If the mating connection position of the mating portion 600 and the fastener 400 is set on the first side 150 of the bed frame 100, that is, the side of the bed frame 100 close to the mattress 200, the mating connection position of the mating portion 600 and the fastener 400 is shielded by the mattress 200, making it inconvenient for the user to operate the mating connection between the two. However, through the arrangement of the embodiment of the present application, it is convenient for the user to operate to achieve the connection and disassembly of the mating portion 600 and the fastener 400.

[0094] Here, the connecting member 500, the fastener 400 and the channel 170 are arranged correspondingly, that is, the positions and quantities of the connecting member 500, the fastener 400 and the channel 170 correspond one to one. Figure 3 , here there are four channels 170, see Figure 8 Combined with Fig. 9 , four connecting members 500 are provided correspondingly, and four fasteners 400 are provided, and then the matching portion 600 on each connecting member 500 can match with the corresponding fastener 400. Of course, it can be understood that in other embodiments, these components may not be provided one by one, for example, several connecting members 500 may share the same channel 170; the matching portions 600 of several connecting members 500 may be connected to the same fastener 400, etc., and the examples in this embodiment do not constitute an improper limitation thereto.

[0095] In addition, in some embodiments, the intervals between the channels 170 can be set larger, so as to better tighten the mattress 200 through the connector 500 and make it fit the bed frame 100. Figure 3 In the embodiment, the two channels 170 on the second bed frame 100 are spaced apart, for example, respectively close to the left and right sides of the bed frame 100 , and the two channels 170 on the fourth bed frame 100 are also spaced apart, for example, respectively close to the left and right sides of the bed frame 100 .

[0096] In some embodiments, the connector 500 may be a braided belt or a nylon belt, for example, the connector 500 may also be a cloth belt made of other materials, or a chain, etc. Therefore, the connector 500 has good tensile strength and is not easily deformed, which helps to maintain the position of the mattress 200 and reduce the slippage of the mattress 200 compared to the bed frame 100.

[0097] In some embodiments, see Figure 3, the bed frame 100 is provided with a channel 170 in an area near the feet and / or in an area near the buttocks. Exemplarily, the second bed frame 100 and / or the fourth bed frame 100 are provided with a channel 170. The position on the mattress 200 connected to the connecting member 500 may roughly correspond to the position where the channel 170 is provided, for example, in an area near the buttocks and feet, but it may also be provided farther from the channel 170, and the examples in this embodiment do not constitute an undue limitation thereto.

[0098] Here, the second bed frame 100 and the fourth bed frame 100 are respectively provided with the channel 170 as an example for illustration. Figure 6 and Figure 7 , which shows the relative positional relationship between the connector 500 and the channel 170 , but it is only for illustration. In practice, the connector 500 may be located at other positions within the channel 170 .

[0099] by Figure 6 Taking the state shown as an example, no matter the area near the head or the area near the feet of the bed frame 100 is lifted, the mattress 200 at the hip position is subjected to the force F1 with an upward component and moves upward. Here, the connector 500 can effectively pull the mattress 200 at the hip position to prevent the mattress 200 from moving upward, thereby improving the fit between the mattress 200 and the bed frame 100. Figure 7 For example, when the bed frame 100 is raised or lowered, the mattress 200 at the foot position is often subjected to a force F2 having backward and upward components and is displaced backward and upward. When the connecting piece 500 is connected to the bed frame 100, due to the small deformation and tensile resistance of the connecting piece 500 itself, the connecting piece 500 can effectively prevent the mattress 200 from displacing backward and upward, which helps to improve the fit between the mattress 200 and the bed frame 100.

[0100] In some embodiments, see Fig.10 , one end of the connecting member 500 is directly connected to the mattress 200. In other embodiments, please refer to Fig.11 , a reinforcing part 210 is provided on the mattress 200. For example, four reinforcing parts 210 are provided here, and the four reinforcing parts 210 are provided one by one with four connecting members 500, that is, each connecting member 500 is connected to a corresponding reinforcing part 210 (see the schematic diagram of the matching between the connecting member 500 and the reinforcing part 210 for details). Fig.12 Of course, it can be understood that, in other embodiments, the number of the reinforcing parts 210 is not limited to the above, and generally, the number of the reinforcing parts 210 can match the number of the connecting members 500.

[0101] Please refer to this for further information. Fig.12, the reinforcing part 210 has a connecting surface 211, and the connecting member 500 is connected to the connecting surface 211. Therefore, the connecting member 500 and the mattress 200 are not in point contact but in surface contact, which helps to strengthen the strength of the connection position between the two, so that the connecting member 500 drives a larger surface of the mattress 200 to move during operation, rather than driving a smaller area of ​​the mattress 200 (for example, an approximately linear area on the mattress 200) to move, thereby reducing the deformation of the mattress 200 when the connecting member 500 constrains the mattress 200. Exemplarily, the reinforcing part 210 can be roughly plate-shaped.

[0102] In some embodiments, see Fig.13 , the mating portion 600 includes a first sub-portion 610 and a second sub-portion 620, and the aforementioned connector 500 is clamped between the first sub-portion 610 and the second sub-portion 620. Exemplarily, the first sub-portion 610 and the second sub-portion 620 can form a detachable mating connection, for example, the first sub-portion 610 and the second sub-portion 620 form a detachable connection through magnetism, or the first sub-portion 610 and the second sub-portion 620 form a threaded connection, or the first sub-portion 610 and the second sub-portion 620 form a snap connection or a rivet connection, or the first sub-portion 610 and the second sub-portion 620 are connected by threads or other means, and magnetic adsorption is also formed between the first sub-portion 610 and the second sub-portion 620. Of course, in other embodiments, the first sub-portion 610 and the second sub-portion 620 can also be detachably connected or non-detachably connected in other ways, for example, the first sub-portion 610 and the second sub-portion 620 can be connected by welding, etc., and the examples in this embodiment do not constitute an improper limitation thereto.

[0103] In some embodiments, the matching portion 600 and the fastener 400 are detachably connected by magnetism, that is, the matching portion 600 and the fastener 400 are both magnetic, and the two can be magnetically attracted to each other to form a detachable connection.

[0104] For example, the mating portion 600 and the fastener 400 are detachably connected by magnetism. Fig.14 The fastener 400 has a protruding portion 410, such as a protruding column, etc. In addition, illustratively, the fastener 400 may also be provided with a connecting hole 420 for connecting it to the second side 160 of the bed frame 100 by screws. Of course, in other embodiments, the connection method of the fastener 400 and the bed frame 100 is not limited to the above.

[0105] Corresponding to the protrusion 410, see Fig.15A recessed portion 630, such as a through hole or a groove, is provided on the mating portion 600. When the mating portion 600 includes a first sub-portion 610 and a second sub-portion 620, usually the first sub-portion 610 and the second sub-portion 620 are correspondingly provided with recessed portions 630. For example, the first sub-portion 610 and the second sub-portion 620 are both correspondingly provided with through holes as the recessed portions 630, and the through holes of the two are connected and communicated with each other.

[0106] When the mating portion 600 is mated with the fastener 400, at least a portion of the protruding portion 410 is mated in the recessed portion 630. Fig.16 As shown, the protrusion 410 passes through the recess 630. Fig.17 As shown, it shows a schematic diagram of the mating portion 600 mating with the fastener 400 and fixing the connecting member 500. In order to avoid the protruding portion 410, an avoidance hole may be provided on the connecting member 500 corresponding to the protruding portion 410, but it may not be provided. The example in this embodiment does not constitute an undue limitation to it.

[0107] It is understandable that in other embodiments, the protruding portion 410 may be provided on the mating portion 600 and the recessed portion 630 may be provided on the fastener 400 , and the example in this embodiment does not constitute an undue limitation thereto.

[0108] In some embodiments, on the basis of the detachable connection formed between the mating portion 600 and the fastener 400 by magnetism, the magnetization direction of the mating portion 600 is perpendicular to the surface of the bed frame 100. Usually, the bed frame 100 is placed on a horizontal ground, and the magnetization direction of the mating portion 600 is also perpendicular to the horizontal direction, for example, approximately in the vertical direction.

[0109] Here, the magnetization direction of the magnet at the matching part 600 is perpendicular to the surface of the bed frame 100 close to the ground, that is, there is only one magnetic pole on the plane of the bed frame 100. During installation, the matching part 600 can be automatically centered on the fastener 400, and the installation difficulty is convenient for magnetized magnets in other directions.

[0110] Exemplarily, if the mating portion 600 adopts a structure including a first sub-portion 610 and a second sub-portion 620, the first sub-portion 610 can be set as the N pole of the mating portion 600, and the second sub-portion 620 can be set as the S pole of the mating portion 600, or vice versa.

[0111] In a further example, on the basis of adopting the magnetic adsorption solution, the aforementioned protruding portion 410 and recessed portion 630 are also provided. In this case, the magnetization direction of the matching portion 600 is also the axial direction of the protruding portion 410 and / or the recessed portion 630 .

[0112] It can be seen that when the connection method between the mating part 600 and the fastener 400 is set to a magnetically-fitted structure, the structure is simple to install, and the self-positioning function can be achieved by setting the magnetic pole position, so that the user can more easily achieve accurate fit between the mating part 600 and the fastener 400.

[0113] However, since the matching portion 600 and the fastener 400 are magnetically matched, an interfering magnetic field will be formed, which may interfere with medical equipment when used in the medical field. For example, when the electric bed with this structure is used as a hospital bed, this may cause this situation.

[0114] Therefore, in some embodiments of the present application, the mating portion 600 and the fastener 400 are mated and connected in a non-magnetic manner. Correspondingly, the mating portion 600 and the connector 500 can also be connected in a non-magnetic manner.

[0115] For example, in some embodiments, see Fig.18 The fastener 400 is provided with a protruding portion 410, and the protruding portion 410 is provided with at least one protrusion 411, and the protrusion 411 protrudes from the protruding portion 410 along the radial direction of the protruding portion 410. Correspondingly, please refer to Fig.19 The mating portion 600 is provided with a recessed portion 630, which includes a through hole. The cross section of the through hole in the recessed portion 630 is adapted to the cross section of the protruding portion 410 at the position where the protrusion 411 is provided, so that at least a part of the protruding portion 410 and the protrusion 411 can pass through the through hole.

[0116] For example, see Fig. 20 When the matching portion 600 is matched with the fastener 400, after the protruding portion 410 passes through the through hole of the recessed portion 630 and rotates relative to the recessed portion 630, the protrusion 411 leaves the range of the recessed portion 630, and then the protrusion 411 abuts against the side of the matching portion 600 away from the bed frame 100, thereby achieving the matching connection between the fastener 400 and the matching portion 600. When disassembly is required, the matching portion 600 and the recessed portion 630 are rotated relative to the protruding portion 410 again, and the protrusion 411 returns to the range of the recessed portion 630 again, and then the protruding portion 410 and the protrusion 411 can pass through the recessed portion 630, thereby releasing the matching between the protruding portion 410 and the recessed portion 630.

[0117] Here, the number of protrusions 411 may be set to N, where N is a natural number approximately equal to 1. The protrusions 411 on the protruding portion 410 pass through the through hole of the recessed portion 630. After rotating 180 / N°, the protruding portion 410 and the recessed portion 630 may be matingly connected. Figures 18 to 20In the figure, the number of protrusions 411 is set to 3, that is, N is 3, and the three protrusions 411 are evenly arranged along the circumferential direction. Of course, in other embodiments, the number N may be different from the example in the figure.

[0118] Also illustratively, see Fig. 22 The recessed portion 630 is provided with a flange portion 631 extending radially inwardly of the through hole. The flange portion 631 has a flange surface 632 on a side away from the protruding portion 410. Figure 22-Figure 24 As shown, with particular reference to Fig. 22 and Fig.24 , the flange surface 632 is inclined. Here, please refer to Fig. 22 The flange 631 is provided with two symmetrical flanges corresponding to the two protrusions 411 of the protruding portion 410. In other embodiments, when the number of protrusions 411 is different, the number of flanges 631 is also different. When the protruding portion 410 is provided on the fastener 400, the side of the flange 631 away from the protruding portion 410, that is, away from the fastener 400, is usually away from the bed frame 100.

[0119] Also, see Fig.23 In some examples, a stopper 633 may be provided on the flange surface 632. The stopper 633 is located at the end of the motion path of the protrusion 411 on the flange surface 632 to limit the protrusion 411 and prevent the protrusion 411 from falling out of the flange surface 632 due to excessive rotation by the user. Fig.23 The direction toward the outside of the paper is the height direction, and the flange surface 632 gradually increases in the height direction along the movement path of the protrusion 411 to be inclined, and the stop portion 633 can be located at the end of the higher side of the flange surface 632.

[0120] After the protruding portion 410 is inserted into the through hole, the protrusion 411 moves to the side of the flange portion 631 having the inclined flange surface 632, and then the protruding portion 410 is rotated to make the protrusion 411 rotate along the flange surface 632. Since the flange surface 632 is inclined, as the protrusion 411 rotates, the protrusion 411 and the flange surface 632 approach each other, and the rotational torque gradually increases, so that the fastener 400 and the matching portion 600 are tightly matched with each other. Please refer to Fig.25 , which is a schematic diagram showing a state in which the mating portion 600 and the fastener 400 have completed mating and fixed the connecting member 500.

[0121] It can be understood that in the above-mentioned embodiment of setting the flange surface 632, the axial length of the protruding portion 410 only needs to be sufficient to enable the protrusion 411 to cooperate with the flange surface 632 after it cooperates with the recessed portion 630, and the flange portion 631 and the flange surface 632 are located in the through hole of the recessed portion 630, so the axial length of the protruding portion 410 can be set shorter.

[0122] See also Fig.26 As shown, after the installation is completed, the required length of the connector 500 is L1, but in order to match and connect the matching portion 600 on the connector 500 to the fastening portion, it is necessary to apply a force to the connector 500 in a direction away from the mattress 200, and then the required length of the connector 500 during installation is L2, and L2 is longer than L1. In order to achieve installation, it is necessary to set the length of the connector 500 to L2, which results in its actual length being longer than the required length L1 after installation, and then the mattress 200 has a certain movable space. If the difference between L2 and L1 is smaller, the sliding space of the mattress 200 is smaller, and the length of L2 is related to the length L3 of the protruding portion 410. The smaller the length L3 of the protruding portion 410, the smaller L2 can be. The embodiment of the present application can shorten the axial length of the protruding portion 410, that is, the length of L3, and then reduce L2 to reduce the displacement of the mattress 200.

[0123] It is understandable that in the above-mentioned embodiments, the fastener 400 is provided with a protruding portion 410, and the matching portion 600 is provided with a recessed portion 630 corresponding to the protruding portion 410. However, in other embodiments, the matching portion 600 may be provided with a protruding portion 410, and the fastener 400 may be provided with a recessed portion 630, and the example in this embodiment does not constitute an improper limitation thereto.

[0124] In some embodiments, see Fig. 27, an additional part 700 may also be provided, and the matching part 600 and the fastener 400 are connected by the additional part 700. Exemplarily, the additional part 700 is matched with the fastener 400, and the matching part 600 is clamped between the additional part 700 and the fastener 400. The matching connection method between the additional part 700 and the fastener 400 may be threaded connection, clamping, magnetic connection, etc., and the examples in this embodiment do not constitute an improper limitation thereto. For example, a first thread segment 710 is provided on the additional part 700, a matching hole 640 is provided on the matching part 600 as a avoidance, and a second thread segment 430 is provided on the fastener 400. The additional part 700 and the fastener 400 may be meshed with each other through the first thread segment 710 and the second thread segment 430, thereby achieving a matching connection. Among them, the first thread segment 710 may be an external thread, and the second thread segment 430 may be an internal thread. Here, if the connecting member 500 hinders the mating connection between the accessory 700 and the fastener 400, a structure such as an avoidance hole can be provided on the connecting member 500, such as the aforementioned mating hole 640, which is easy to understand for those skilled in the art.

[0125] For some further examples, see Fig.28 , an extension section 720 may be provided on the outside of the first threaded section 710. The inside of the first threaded section 710 may have a section without threads, for example, the part of the mating hole 640 that penetrates the mating portion 600 may not have threads, or the inside of the extension section 720 may be entirely the first threaded section 710. The example in this embodiment does not constitute an improper limitation to it. Corresponding to the extension section 720, the fastener 400 is provided with an extension section 440. Please refer to the example in this embodiment. Fig.29 An extension space 441 is provided in the extension section 440 , and the extension space 441 is connected to the aforementioned second threaded section 430 to accommodate the extension section 720 .

[0126] When in use, when the assembly is completed, the first threaded section 710 of the attachment 700 is engaged with the second threaded section 430 of the fastener 400, and at the same time, the extension section 720 is accommodated in the extension space 441. Exemplarily, the inner wall of the extension section 440 wraps at least a portion of the extension section 720. Generally, the extension section 720 does not protrude from the extension space 441 to avoid forming a protruding structure, but the example in this embodiment does not constitute an undue limitation thereto.

[0127] Here, the matching length of the first thread segment 710 and the second thread segment 430 will affect the connection strength. However, if the matching length of the first thread segment 710 and the second thread segment 430 is too long, the user needs to twist more turns when using it, which increases the installation time. In some embodiments of the present application, an extension segment 720 is provided, and the connection strength is increased by the matching of the extension segment 720 and the extension segment 440, so that the matching length of the first thread segment 710 and the second thread segment 430 can be set to be smaller to reduce the installation time.

[0128] In addition, it can be understood that the additional component 700 and the matching portion 600 shown in the drawings of the present application are two separate components, while in other embodiments, the additional component 700 and the matching portion 600 can also be an integrated component, that is, the additional component 700 can be a part of the matching portion 600, and then the above embodiment can also be understood as the fastener 400 and the matching portion 600 are connected by threaded matching. In addition, in other embodiments, the protruding portion 410 in any of the above embodiments can be provided with an external thread, and the recessed portion 630 can be provided with an internal thread, and the protruding portion 410 and the recessed portion 630 can be meshed with each other through the external thread and the internal thread, thereby achieving a matching connection.

[0129] For example, see Fig.30 Alternatively, the fastener 400 may be provided with a protruding portion 410, the protruding portion 410 may be provided with an external thread as the aforementioned second thread segment 430, and the attachment 700 may be provided with an internal thread as the aforementioned first thread segment 710, and the two may be threadedly matched to achieve connection. Fig.31 As shown, the protruding portion 410 may be provided with an internal thread, and the accessory 700 may be provided with an external thread correspondingly, as long as the two can be connected to each other in a coordinated manner.

[0130] In these embodiments, since magnetic attraction is not used, each component does not generate a magnetic field, does not interfere with the operation of the medical device, and can be applied to the medical field. In addition, the installation and removal between the fastener 400 and the matching part 600 in these embodiments are relatively simple, which is convenient for users to operate.

[0131] In some embodiments, embodiments of the present application provide a snap-fit ​​structure to achieve the matching between the matching portion 600 and the fastener 400 .

[0132] See also Fig.32The fastener 400 includes a third side 470, a limiting portion 450 is provided on the third side 470 of the fastener 400, and a limiting groove 451 is provided on the limiting portion 450, and the limiting groove 451 is used to cooperate with the matching portion 600 to prevent the matching portion 600 from falling out. Exemplarily, two limiting portions 450 arranged at intervals may be provided, and a space for the connector 500 to pass through is formed between the two limiting portions 450. Of course, in some embodiments, the limiting portion 450 may not be provided or other numbers of limiting portions 450 may be provided, and the examples in this embodiment do not constitute an improper limitation thereto.

[0133] Please refer to Fig.33 , the fastener 400 also includes a fourth side 480, and the third side 470 and the fourth side 480 can be opposite sides, such as an upper side and a lower side. A fastening groove 460 is provided on the fourth side 480 of the fastener 400, and the fastening groove 460 includes a first slot 461, a second slot 462 and a third slot 463 which are arranged in sequence, and the entrance of the fastening groove 460 is located on the side of the first slot 461 away from the third slot 463. Among them, from the first slot 461, the second slot 462 to the third slot 463, the width of the fastening groove 460 gradually increases. Exemplarily, the first slot 461 has a first width, the second slot 462 has a second width, the third slot 463 has a third width, and the first width is less than the second width and less than the third width.

[0134] Here, in order to achieve the matching connection between the fastener 400 and the matching portion 600, Fig.32 and Fig.33 Based on the combination Fig.34 In the embodiment of the present application, a locking member 800 is also provided. The locking member 800 includes a first rod 810 and a second rod 820 arranged at intervals, and a first spacing is provided between the first rod 810 and the second rod 820. One end of the same side of the first rod 810 and the second rod 820 extends outwardly on a side away from each other to provide a first check end 811 and a second check end 821, and a second spacing is provided between the first check end 811 and the second check end 821, and the second spacing is greater than the first spacing. In addition, the second width is less than the second spacing, and the third width is greater than the second spacing. The first check end 811 and the second check end 821 can be arranged obliquely to the first rod 810 and the second rod 820. In addition, one end of the other side of the first rod 810 and the second rod 820 can be connected to each other to form a stop fitting portion 830.

[0135] When using, refer to Fig.35 The matching portion 600 can be inserted into the limiting groove 451 of the upper limiting portion 450 on the third side 470 of the fastener 400 .

[0136] Please combine Fig.33 and Fig.34The first check end 811 and the second check end 821 of the locking member 800 first enter the first slot 461 from the entrance of the fastening slot 460. At this time, the first check end 811 and the second check end 821 contact the inner wall of the first slot 461. Due to the limitation of the inner wall of the first slot 461, the second distance between the first check end 811 and the second check end 821 will become smaller compared to the state without external force.

[0137] See also Fig.36 As the locking component 800 moves, the first check end 811 and the second check end 821 enter the second slot 462. The first check end 811 and the second check end 821 are no longer constrained by the inner wall of the first slot 461, but are constrained by the inner wall of the second slot 462. Since the second width of the second slot 462 is greater than the first width of the first slot 461, the second distance between the first check end 811 and the second check end 821 can be correspondingly increased. At this time, it is difficult for the first check end 811 and the second check end 821 to return to the first slot 461, thereby forming a fit between the locking component 800 and the fastener 400.

[0138] See also Fig.37 As the locking member 800 moves, the first check end 811 and the second check end 821 enter the third slot 463. At this time, the first check end 811 and the second check end 821 are fully extended. For example, when extended, they will move along the step surface formed at the junction of the second slot 462 and the third slot 463 and collide with the inner wall of the third slot 463, which may produce a slight sound. The sound can be used as a prompt to remind the user that it has been installed in place. At the same time, in this state, please combine Fig.38 The stopper matching portion 830 formed by connecting the first rod 810 and the second rod 820 is located at a position close to the surface of the third side 470 of the fastener 400 to reduce the possibility of the locking member 800 falling off. Thus, the locking match is completed.

[0139] When the mating connection needs to be released, the user can pull the locking member 800 to the second slot 462 position by applying a little pulling force, so that the mating portion 600 can be separated from the locking member.

[0140] This snap-fit ​​structure will not form an additional magnetic field, will not interfere with medical equipment, and is relatively easy to install and remove.

[0141] It can be seen that in the embodiment of the present application, the mating connection between the mating portion 600 and the fastener 400 is easy to achieve and release, and the user's operation is very convenient.

[0142] Accordingly, see Figures 1 to 38, the embodiments of the present application further provide a support pad positioning structure, which is used to position a first component on a second component, one of the first component and the second component is a support pad, and the other is a support frame. Exemplarily, the support pad can be the aforementioned mattress 200, and the support frame can be the aforementioned bed frame 100; another exemplary embodiment, the support pad can be a seat cushion, and the support frame can be a recliner, etc. It can be understood that the support pad positioning structure is more suitable for a support frame that can change its state by mechanical drive, and can also be suitable for a support frame that can change its state by human drive. Of course, the examples in the embodiments of the present application do not constitute an undue limitation thereto.

[0143] The first component has a first side 150 and a second side 160 opposite to each other, and a channel 170 penetrating the first side 150 and the second side 160 is arranged on the first component, and a fastener 400 is also arranged on the second side 160 of the first component; the second component is arranged on the first side 150 of the first component, and a connecting member 500 is arranged on the second component, and the connecting member 500 is provided with a mating portion 600.

[0144] Here, the connector 500 may pass through the passage 170 so that the mating portion 600 is mated with the fastener 400 .

[0145] For the specific structure, setting position and matching relationship of the matching part 600, fastener 400 and other components, please refer to the aforementioned embodiments. In order to avoid the text of this application being too lengthy, this application will not elaborate on it.

[0146] Accordingly, an embodiment of the present application further provides a method for using an electric bed, comprising the following steps:

[0148] S200. Make the connecting member 500 on the mattress 200 pass through the channel 170 on the bed frame 100 so that the matching portion 600 on the connecting member 500 matches with the fastener 400 on the second side 160 of the bed frame 100, thereby relatively fixing the bed frame 100 and the mattress 200.

[0149] Among them, the relative positions, connection relationships and assembly methods of various components such as the connecting part 500, the channel 170, the matching part 600 and the fastener 400 can refer to any of the aforementioned embodiments, which are the same as the descriptions in the aforementioned structural embodiments.

During installation, the axially magnetized magnet can be automatically centered, and the installation between the matching portion 600 and the fastener 400 is very convenient.
