Abstract
Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of support pad positioning, in particular to an electric bed and a support pad positioning structure. BACKGROUND
[0002] An electric bed is a device that can control at least a part of a bed frame to be lifted by an electric mode, so that the height of the head, foot or other parts of the bed plate changes, thereby realizing the change of the bending degree of the bed plate. The electric bed can be widely applied in different scenes such as daily life and hospital care to meet the use requirements of users and improve the use comfort.
[0003] During the lifting of the bed frame, the mattress may slip, therefore, the existing electric bed often sets a support protruding from the bed surface at the foot position to prevent the mattress from slipping backward. However, this foot support makes the user feel uncomfortable when getting on and off the bed, and even if this support is set, when the mattress exceeds the height of the support, the mattress is still easy to fall out.
[0004] At the same time, when the bed frame is lifted, the support at the foot position cannot guarantee the fit between the mattress and the bed frame, and the middle part of the mattress is easy to arch. Moreover, in the lifted state, the mattress has a downward sliding trend, which will produce a strong extrusion on the support at the foot position, thereby causing the deformation of the mattress and affecting the service life of the mattress.

DETAILED DESCRIPTION
[0044] The technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

In the present application, the orientation words such as "upper", "lower", "left", "right" generally refer to the upper, lower, left and right of the device in the actual use or working state, and specifically refer to the figure direction in the drawings.
[0045] In addition, the terms "first" and "second" are only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first" and "second" can explicitly or implicitly include at least one of the features.
[0046] The present application provides an electric bed and a support pad positioning structure, which are described in detail below. It should be noted that the description order of the following embodiments is not limited as the preferred order of the embodiments of the present application. In the following embodiments, the description of each embodiment has its own emphasis, and the parts not described in detail in a certain embodiment can be referred to the related description of other embodiments.
[0047] The embodiments of the present application provide an electric bed, please refer to Figure 1 which includes a bed frame 100 and a mattress 200, and the mattress 200 is arranged on the bed frame 100.
[0048] Among them, please combine Figure 2The bed frame 100 can be generally arranged on a bottom support 300, which can include a bed leg or the like, as known by those skilled in the art. Of course, the bottom support 300 in the drawings of the present application is merely an example and does not constitute an improper limitation on the present application.
[0049] Here, the electric bed further includes a driving member (not shown in the drawings), which can be a driving motor, an electric cylinder, a pneumatic cylinder or the like. The driving member is connected to the bed frame 100 and can drive at least a part of the bed frame 100 to be lifted.
[0050] For example, here, 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 connected in sequence. When a user lies on the electric bed, the first bed frame 110 generally corresponds to the position of the head and back of the user, the second bed frame 120 generally corresponds to the position of the hips of the user and can also be referred to as a hip bed frame, the third bed frame 130 generally corresponds to the position of the thighs of the user, and the fourth bed frame 140 generally corresponds to the position of the lower legs and feet of the user. Two driving members are respectively connected to the first bed frame 110 and the third bed frame 130, and through the driving of the driving members, the first bed frame 110 and the third bed frame 130 can be lifted to adjust the posture of the bed frame 100. It can be understood that the arrangement of the bed frame 100 and the driving member is not limited to the above, and the bed frame 100 can also have other forms, such as only having three parts of the first bed frame 110, the second bed frame 120 and the third bed frame 130 or more or fewer parts, etc.; the driving member can also be connected to the bed frame 100 in a different manner, such as only arranging one driving member connected to any part of the bed frame 100 and capable of driving the part to be lifted. This can be realized by those skilled in the art, and the examples in the present embodiment do not constitute an improper limitation on the present application.
[0051] For example, Figure 2 That is, a state of the mattress 200 after being lifted is shown. It can be understood that this is merely an example and does not constitute an improper limitation on the present application. In some embodiments, after the bed frame 100 is lifted, the bed frame 100 and the mattress 200 can also be in other inclined states.
[0052] 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 action of gravity, the mattress 200 will slide downward and change the relative position between the mattress 200 and the bed frame 100, thereby causing a part of the mattress 200 to bulge or the mattress 200 to be out of the bed frame 100, etc.
[0053] For this purpose, please refer to Figure 3 In the embodiments of the present application, a constraint assembly 400 is arranged on the bed frame 100. Please also refer to Figure 4The constraint assembly 400 comprises a constraint piece 410, which is provided with a constraint section 411 forming a limiting space 412 on the side close to the bed frame 100, and the limiting space 412 is provided with an opening 413 for the positioning piece 400 to enter and exit.
[0054] Here, the constraint piece 410 is further provided with a fixing portion 414 for connecting with the bed frame 100, so that the constraint piece 410 can be fixed on the bed frame 100. The constraint section 411 has a fixed end 4112 and a free end 4111, and the fixed end 4112 is arranged on the fixing portion 414, and the limiting space 412 is located between the constraint section 411 and the fixing portion 414, i.e. on the side of the constraint section 411 close to the bed frame 100. Of course, it can be understood that in some embodiments, the fixing portion 414 can not be provided, and the fixed end 4112 of the constraint section 411 is directly connected to the bed frame 100, and the examples in the present embodiment do not constitute improper limitations.
[0055] Here, please refer to Figure 3 and Figure 5 , the positioning piece 500 is arranged on the mattress 200 corresponding to the constraint assembly 400. Exemplarily, please refer to Figure 5 and Figure 7 , the positions of the constraint assembly 400 and the positioning piece 500 are arranged correspondingly. Exemplarily, please refer to Figure 6 , the connecting belt 600 is arranged on the mattress 200 corresponding to the position of the constraint assembly 400, and the connecting belt 600 has a connecting channel 610, which can be a through hole, etc., and the positioning piece 500 is arranged in the connecting channel 610 of the connecting belt 600 to be fixed with the mattress 200. Of course, it can be understood that in some embodiments, the mattress 200 can be connected to the positioning piece 500 in other ways, such as adhesion, magnetic connection by arranging a magnetic structure, etc., which can be thought of and realized by those skilled in the art, and the examples in the present embodiment do not constitute improper limitations on the present application.
[0056] Here, the positioning piece 500 can pass through the opening 413 corresponding to the constraint assembly 400 and be matched into the limiting space 412, so that the mattress 200 and the bed frame 100 are fixed. Exemplarily, please refer to Figure 4 , in combination with Figure 8 and Figure 9 , along the direction indicated by the arrow in Figure 8 , the positioning piece 500 passes through the opening 413 and moves into the limiting space 412, and in the state shown in Figure 9 , the positioning piece 500 is limited and fixed by the limiting space 412 of the constraint piece 410.
[0057] Thus, in the state that the bed frame 100 is driven and lifted by the driving member, the restraint segment 411 of the at least one set of restraint assembly 400 stops the corresponding positioning member 500, so as to reduce the sliding of the mattress 200 relative to the bed frame 100. Further, the displacement of the mattress 200 is small, the fitting degree of the mattress 200 to the bed frame 100 is high, the mattress 200 is not easy to bulge and is not easy to get out of the range of the bed frame 100, which helps to improve the use comfort of the user, also helps to reduce the damage of the mattress 200, and improves the service life of the mattress 200.
[0058] Meanwhile, in the embodiments of the present application, the restraint assembly 400 and the positioning member 500 are located between the mattress 200 and the bed frame 100, that is, the restraint assembly 400 and the positioning member 500 will not be exposed on the bed tail like the bracket in the prior art, so as not to hinder the user's getting on and off the bed, and also helps to make the electric bed tail more simple and beautiful.
[0059] In some embodiments, the restraint segment 411 is configured to have elasticity, and the restraint segment 411 has a limiting end, exemplarily, please refer to Figure 9 , the free end 4111 of the restraint segment 411 is the limiting end, the opening 413 of the limiting space 412 is located on the side of the limiting end close to the bed frame 100, and the positioning member 500 is clamped and matched in the limiting space 412.
[0060] Exemplarily, the restraint segment 411 is configured to have elasticity, so as to facilitate the positioning member 500 to be matched into the limiting space 412 of the restraint segment 411. For example, when the positioning member 500 passes through the opening 413, the positioning member 500 abuts against the limiting end, the restraint segment 411 elastically deforms to increase the height of the opening 413, so that the positioning member 500 can pass through the opening 413 and enter the limiting space 412, and be clamped and restrained in the limiting space 412 by the restraint segment 411.
[0061] Thus, since the restraint segment 411 can elastically deform, the positioning member 500 can be conveniently moved into the limiting space 412 by applying external force to overcome the elastic force. After the positioning member 500 is located in the limiting space 412, the limiting end stops the positioning member 500 without external force, so that the positioning member 500 is not easy to fall off. When it is necessary to disassemble the positioning member 500 to release the cooperation between the positioning member 500 and the restraint segment 411, external force can be applied again to make the restraint segment 411 elastically deform, so that the height of the opening 413 is increased by the displacement of the limiting end, and then the positioning member 500 can exit the limiting space 412 through the opening 413.
[0062] Exemplarily, the restraint segment 411 can be made of polyurethane, ABS plastic, polycarbonate or other non-plastic materials. Exemplarily, the restraint segment 411 can be arc-shaped.
[0063] Through the arrangement, the positioning member 500 can be conveniently fitted into the limiting space 412, and the connection stability between the limiting member and the positioning member 500 is also high.
[0064] In some embodiments, please continue to refer to Figure 9 The constraint section 411 is arc-shaped, and the end of the constraint section 411 at the opening 413 is provided with a limiting section 415 connected with the constraint section 411 and forming a limiting end portion protruding towards the bed frame 100 at the connection. The limiting end portion can be used to limit and constrain the positioning member 500. Here, the limiting end portion can be the free end 4111 of the constraint section 411 exemplarily.
[0065] Further, when the constraint section 411 is arc-shaped, the limiting space 412 is generally circular, please refer to Figure 6 The positioning member 500 can have a fitting section 510 in a cylindrical shape similar to the arc-shaped constraint section 411, for fitting in the limiting space 412. It can be understood that in other embodiments, the shapes of the constraint section 411 and the limiting space 412 can be different from the above, for example, the limiting space 412 can be constructed as a rectangle or other shapes by the constraint section 411, and the fitting section 510 can also be constructed in a shape similar to the constraint section 411 and the limiting space 412, and the examples in the present embodiment do not constitute undue limitation thereto.
[0066] Further, please continue to refer to Figure 6 The flange section 520 can also be provided on the positioning member 500, and protrudes from the limiting space 412 along the radial direction of the positioning member 500, for limiting the positioning member 500 along the axial direction of the positioning member 500.
[0067] Since the flange section 520 protrudes from the limiting space 412 along the radial direction of the positioning member 500 as observed along the axial direction of the positioning member 500, that is, the diameter of the flange section 520 is greater than that of the fitting section 510 and the limiting space 412, therefore, the flange section 520 cannot pass through the limiting space 412, and in the axial direction, the flange section 520 can abut against the limiting member 410, and the position of the positioning member 500 in the axial direction is limited.
[0068] For example, each set of constraint assemblies 400 is provided with two limiting members 410, and one positioning member 500 is provided corresponding to each set of constraint assemblies 400, and the two ends of the positioning member 500 can be respectively provided with flange sections 520, and the two flange sections 520 are located on the sides away from each other of the two limiting members 410.
[0069] In some embodiments, on the basis that the fitting section 510 of the positioning member 500 is cylindrical, please refer to Figure 8The diameter of the fitting section 510 is set as d, and the height of the opening 413 is set as h. Exemplarily, the minimum distance between the limiting end and the fixed part 414 is the height h of the opening 413, or in the embodiment without the fixed part 414, the minimum distance between the limiting end and the bed frame 100 is the height h of the opening 413.
[0070] Here, the height h of the opening 413 is set to satisfy: d≥h≥0.8*d.
[0071] Exemplarily, h can be any value of 0.8d, 0.85d, 0.87d, 0.88d, 0.895d, 0.897d, 0.9d, 0.92d, 0.95d, 0.96d, d or a range value between any two of them. In another example, the difference h-d is any value of 1mm, 1.1mm, 1.2mm, 1.22mm, 1.24mm, 1.25mm, 1.3mm, 1.33mm, 1.36mm, 1.4mm, 1.5mm or a range value between any two of them. It can be understood that all the values of h are not shown in the example of the embodiment, and in other embodiments, the values of h can be different from the above, and the example in the embodiment does not constitute improper limitation thereto.
[0072] Through the above setting, the positioning member 500 can be limited in the limiting space 412, and when assembling the positioning member 500, the positioning member 500 can be conveniently assembled into the limiting space 412 and disassembled out of the limiting space 412 by applying a force to press the limiting end to displace it.
[0073] In some embodiments, please refer to Figure 10 The bed frame 100 has a first end 210 and a second end 220 opposite along the length direction thereof, exemplarily, Figure 10 The first direction X is also shown in the above, which can be the length direction of the bed frame 100. Here, the constraint assembly 400 includes a first constraint assembly 420, which is arranged on the bed frame 100 close to the first end 210, and the openings 413 of the constraint members 410 in the first constraint assembly 420 are towards the second end 220.
[0074] The first end 210 is close to the foot end of the bed, corresponding to the lower leg and foot of the user, for example, the first constraint assembly 420 can be arranged on the fourth bed frame 140 mentioned above. Of course, in other embodiments, the arrangement position is not limited thereto.
[0075] Therefore, when the electric bed is in the lifting state, for example, the electric bed is in the state shown by Figure 2 or the state shown by Figure 1 towardsFigure 2 When the bed 100 is in the state shown in FIG. 1, the foot region of the mattress 200 has a tendency to slide downwardly and rearwardly. Since the openings 413 of the respective constraint members 410 in the first constraint assembly 420 face the second end 220, i.e., in a direction opposite to the sliding tendency of the mattress 200, the positioning member 500 corresponding to the first constraint assembly 420 cannot be disengaged from the first constraint assembly 420. Thus, the first constraint assembly 420 blocks and reduces the sliding of the positioning member 500 and the mattress 200 connected to the positioning member 500, and makes the mattress 200 more closely fit the bed frame 100.
[0076] Exemplarily, in Figure 9 and Figure 10 , the first constraint assembly 420 includes two constraint members 410. Of course, it can be understood that in other embodiments, the first constraint assembly 420 can include one, three, four, or other number of constraint members 410. For example, the first constraint assembly 420 can include at least two constraint members 410 to achieve a more stable connection. In addition, the respective constraint members 410 in the first constraint assembly 420 can be sequentially arranged along the width direction of the bed frame 100 to correspondingly connect the positioning member 500 extending substantially along the width direction.
[0077] In some embodiments, please refer to Figure 10 , the bed frame 100 also has a third end 230 and a fourth end 240 opposite along the width direction thereof. Exemplarily, Figure 10 also shows a second direction Y, which can be the width direction of the bed frame 100.
[0078] Here, the constraint assembly 400 can also include at least one of a second constraint assembly 430 and a third constraint assembly 440.
[0079] The second constraint assembly 430 is arranged on the bed frame 100 close to the third end 230, and the openings 413 of the respective constraint members 410 in the second constraint assembly 430 face the third end 230 or the fourth end 240.
[0080] The third constraint assembly 440 is arranged on the bed frame 100 close to the fourth end 240, and the openings 413 of the respective constraint members 410 in the third constraint assembly 440 face the fourth end 240 or the third end 230.
[0081] For example, the openings 413 of each constraint member 410 in the second constraint assembly 430 face the third end 230, and the openings 413 of each constraint member 410 in the third constraint assembly 440 face the fourth end 240, that is, the openings 413 of each constraint member 410 in the second constraint assembly 430 and the third constraint assembly 440 face the outside of the bed frame 200; or, the openings 413 of each constraint member 410 in the second constraint assembly 430 face the fourth end 240, and the openings 413 of each constraint member 410 in the third constraint assembly 440 face the third end 230, that is, the openings 413 of each constraint member 410 in the second constraint assembly 430 and the third constraint assembly 440 face the inside of the bed frame 200.
[0082] Here, the second constraint component 430 and the third constraint component 440 each include two constraint members 410. It is understood that in other embodiments, the second constraint component 430 may also include one, three, four, or other numbers of constraint members 410. The third constraint component 440 may also include one, three, four, or other numbers of constraint members 410. For example, both the second constraint component 430 and the third constraint component 440 may include at least two constraint members 410 to achieve a more stable connection. It is understood that the number of constraint members 410 in the second constraint component 430 and the number of constraint members 410 in the third constraint component 440 may be the same or different. Furthermore, the orientation of each constraint member 410 may be the same or different, for example... Figure 9 The second constraint member 410 and the third constraint member 410 together include four constraint members 410, and their orientations can be the same or different.
[0083] Furthermore, each constraint member 410 in the second constraint assembly 430 can be arranged sequentially along the length direction of the bed frame 100, and each constraint member 410 in the third constraint assembly 440 can also be arranged sequentially along the length direction of the bed frame 100, so as to respectively cooperate with and connect to the corresponding positioning member 500 that extends approximately along the length direction.
[0084] Here, when the electric bed is in the raised state, for example, when the electric bed is in... Figure 2 The state shown or by Figure 1 The state shown Figure 2When the state changes as shown, the hip region of the mattress 200 has a tendency to be pulled upward, and since the openings 413 of each of the constraint members 410 in the second constraint assembly 430 and the third constraint assembly 440 are not all facing upward, the positioning member 500 corresponding to the second constraint assembly 430 or the third constraint assembly 440 cannot be disengaged from the second constraint assembly 430 or the third constraint assembly 440, so that the second constraint assembly 430 and the third constraint assembly 440 block and reduce the situation of the positioning member 500 and the mattress 200 connected to the positioning member 500 from slipping and rising upward, so that the mattress 200 is more fitted to the bed frame 100.
[0085] In some embodiments, the constraint assembly 400 can be provided in one group, two groups, three groups, or other numbers, for example, only the first constraint assembly 420 described above. Further, in some embodiments, the number of constraint assemblies 400 is provided as at least two groups to improve its effect. And, at least one group of constraint assemblies 400 is provided along the first direction X, and at least one group of constraint assemblies 400 is provided along the second direction Y, which is at an angle to the first direction X and the second direction Y, that is, not parallel and not coincident.
[0086] For example, the first direction X can be the length direction of the bed frame 100, and the second direction Y can be the width direction of the bed frame 100. For another example, the electric bed includes two groups of constraint assemblies 400, one group of constraint assemblies 400 can be the first constraint assembly 420 described above, and the other group of constraint assemblies 400 can be the second constraint assembly 430 described above. Of course, the examples in the embodiments of the present application do not constitute undue limitation on the present application, and in some embodiments, the first direction X and the second direction Y can also be other directions, and the number and position of the constraint assemblies 400 are not limited to the above.
[0087] In some embodiments, the second constraint assembly 430 and / or the third constraint assembly 440 described above can be provided in the region close to the user's hip, that is, approximately close to the middle region of the bed frame 100. For example, any of the second constraint assembly 430 and the third constraint assembly 440 can be provided on the second bed frame 120 described above.
[0088] In some embodiments, the first constraint assembly 420 described above is provided in a first part of the bed frame 100, and any of the second constraint assembly 430 and the third constraint assembly 440 is provided in a second part of the bed frame 100, that is, the first constraint assembly 420 and the second constraint assembly 430 and / or the third constraint assembly 440 are provided in different parts of the bed frame 100. In the lifting state of the electric bed, the inclination states of the first part and the second part are different, for example, the directions of inclination and / or the inclination angles to the horizontal plane are different.
[0089] Exemplarily, the first constraint assembly 420 is arranged on the fourth bed frame 140, and the second constraint assembly 430 and / or the third constraint assembly 440 are arranged on the second bed frame 120, and the second bed frame 120 and the fourth bed frame 140 are in different inclined states in the lifting state of the electric bed. For example, the second bed frame 120 is substantially in a horizontal state, and the fourth bed frame 140 is in an inclined state to the horizontal state.
[0090] In some embodiments, please refer to Figure 10 , Figure 9 In some embodiments, please refer to Figure 11 , the opening 413 of each constraint member 410 of the first constraint assembly 420 is directed towards the second end 220. Please refer to Figure 5 and Figure 6 , the positioning member 500 extending in the direction of the first end 210 to the side of the constraint member 410 close to the first end 210 and connected with the mattress 200. It can be understood that the connection can be direct or indirect, for example, in the embodiment provided with the connecting belt 600, that is, the connecting belt 600 connected with the positioning member 500 extends to the side of the constraint member 410 close to the first end 210 and is connected with the mattress 200, specifically, the connecting belt 600 and the stitching 620 of the mattress 200, that is, the connecting position of the connecting belt 600 and the mattress 200, is located on the back side of the direction of the opening 413 of the corresponding constraint member 410. Thus, according to the direction of the opening 413 and the direct or indirect connection position of the positioning member 500 and the mattress 200, the displacement of the mattress 200 relative to the bed frame 100 can be reduced, thereby achieving a better effect of limiting the mattress 200.
[0091] Correspondingly, in some embodiments, the second constraint assembly 430 and / or the third constraint assembly 440 can be the same as the first constraint assembly 420, and the stitching 620 of the mattress 200 (that is, the connecting position of the connecting belt 600 and the mattress 200, and the indirect connecting position of the positioning member 500 and the mattress 200) is located on the opposite side of the direction of the opening 413 of the corresponding constraint member 410 in the corresponding constraint assembly 400. That is, the direct connecting position or the indirect connecting position of the positioning member 500 and the mattress 200 is located on the opposite side of the direction of the opening 413 of the corresponding constraint member 410 in the corresponding constraint assembly 400.
[0092] Exemplarily, the C2 direction in FIG. 13 exemplarily shows the opening 413 orientation of each of the restraint members 410 in the second restraint assembly 430.

Please refer to Figure 12 , Figure 12 for more information.

Here, the opening 413 of each of the restraint members 410 in the third restraint assembly 440 is oriented towards the fourth end 240, i.e. towards the outer side of the bed frame 200. The positioning member 500" cooperating with the third restraint assembly 440 can extend to the side of the restraint members 410 in the third restraint assembly 440 close to the third end 230 to connect with the mattress 200. Figure 12 Exemplarily, the C2 direction in FIG. 15 exemplarily shows the opening 413 orientation of each of the restraint members 410 in the second restraint assembly 430. Here, it is different from the example shown in
[0094] Figure 13 , Figure 13 , the opening 413 of each of the restraint members 410 in the second restraint assembly 430 is oriented towards the fourth end 240, i.e. towards the inner side of the bed frame 200. Please refer to Figure 12 for more information. Figure 14 The positioning member 500' cooperating with the second restraint assembly 430 can extend to the side of the restraint members 410 in the second restraint assembly 430 close to the third end 230 to connect with the mattress 200.
[0095] Figure 13 Exemplarily, the C3 direction in FIG. 16 exemplarily shows the opening 413 orientation of each of the restraint members 410 in the third restraint assembly 440. Here, it is different from the example shown in Figure 12 , the opening 413 of each of the restraint members 410 in the third restraint assembly 440 is oriented towards the third end 230, i.e. towards the inner side of the bed frame 200. The positioning member 500" cooperating with the third restraint assembly 440 can extend to the side of the restraint members 410 in the third restraint assembly 440 close to the fourth end 240 to connect with the mattress 200.
[0096] Correspondingly, please refer to Figures 1 to 14 The embodiments of the present application also provide a support cushion positioning structure for positioning a first component on a second component, one of the first component and the second component being a support cushion and the other being a support frame. Exemplarily, the support cushion can be the aforementioned mattress 200, and the support frame can be the aforementioned bed frame 100; or, the support cushion can be a seat cushion, and the support frame can be a recliner chair, etc. It can be understood that the support cushion positioning structure is more suitable for a support frame that is driven by a machine to change its state, and is also suitable for a support frame that is driven by human power to change its state.

Here, the connecting positions of the positioning members 500 and the mattress 200 are located on the opposite sides of the openings 413 of the restraint members 410 in the corresponding restraint assemblies 400.
[0107] In use, first, the positioning members 500 are sleeved into the connecting belts 600 on the mattress 200, and then the mattress 200 is placed on the bed frame 100, and the positioning members 500 are pulled so as to be clamped into the corresponding restraint assemblies 400 installed on the bed frame 100, and one positioning member 500 can cooperate with two or more restraint members 410. After all the positioning members 500 cooperate with the corresponding restraint members 410, the installation is completed.
[0108] When the electric bed is raised, the mattress 200 in the foot region has a tendency to move backward, and the mattress 200 in the hip region has a tendency to rise. The connecting belt 600 in the foot region is pulled backward, and the connecting belt 600 in the hip region is pulled upward. Due to the direction of the openings 413 of the restraint members 410, the restraint members 410 can block the positioning members 500, so that the mattress 200 is attached to the bed frame 100.
[0109] Embodiment 2

The connecting position of the positioning member 500 and the mattress 200 is on the opposite side of the corresponding constraint assembly 400 where the opening 413 of the constraint member 410 is towards.
[0114] In use, first, the positioning member 500 is sleeved into the connecting belt 600 on the mattress 200, then the mattress 200 is placed on the bedstead 100, the positioning member 500 is pulled, each positioning member 500 is respectively clamped into the corresponding constraint assembly 400 arranged on the bedstead 100, one positioning member 500 can be matched with two or more constraint members 410. After all the positioning members 500 are matched with the corresponding constraint members 410, the installation is completed.
