Description

Technical Field

[0001] This application relates to the field of support pad positioning technology, specifically to an electric bed and a support pad positioning structure. Background Technology

[0002] An electric bed is a device that allows for the electric control of at least a portion of the bed frame to raise, thereby changing the height of the headboard, footboard, or other parts of the bed board, and thus varying the degree of curvature of the bed board. Electric beds can be widely used in various scenarios such as daily life and hospital care to meet user needs and improve comfort.

[0003] During the process of raising the bed frame, the mattress may slip. Therefore, existing electric beds often have a support protruding from the bed surface at the foot of the bed to prevent the mattress from sliding backward. However, this foot support can cause discomfort for users when getting into and out of bed, and even with this support, the mattress can still easily slip off when it exceeds the height of the support.

[0004] Meanwhile, when the bed frame is raised, the footrests cannot guarantee a proper fit between the mattress and the frame, causing the center of the mattress to arch. Furthermore, when raised, the mattress's downward sliding motion puts significant pressure on the footrests, potentially leading to mattress deformation and shortening its lifespan.

Detailed Implementation

[0059] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of this application and are not intended to limit this application. In this application, unless otherwise stated, directional terms such as "up," "down," "left," and "right" generally refer to up, down, left, and right in the actual use or working state of the device, specifically the drawing directions in the accompanying drawings.

[0060] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0061] This application provides an electric bed and a support pad positioning structure, which will be described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments of this application. Furthermore, in the following embodiments, the descriptions of each embodiment have their own emphasis; parts not described in detail in a certain embodiment can be referred to in the relevant descriptions of other embodiments.

[0062] An embodiment of this application provides an electric bed; please refer to [link / reference]. Figure 1 It 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 each other. Typically, the first side 150 is the upper side and the second side 160 is the lower side. The mattress 200 is disposed on the first side 150 of the bed frame 100, that is, the mattress 200 is disposed on the bed frame 100.

[0063] In this regard, please combine Figure 2The bed frame 100 is typically mounted on a bottom support 300, which may include bed legs, etc., as is well known to those skilled in the art. It is understood that the bottom support 300 in the accompanying drawings is merely an example and does not constitute an undue limitation on this application.

[0064] Here, the electric bed also includes a drive component (not shown in the figure), which can be a drive motor, electric cylinder, pneumatic cylinder, etc. The drive component is connected to the bed frame 100, thereby driving at least a portion of the bed frame 100 to rise. The specific location and number of the drive component can be set according to actual needs. Electric beds generally include drive components such as motors for driving the bed frame to rise, which are well known to those skilled in the art and can be designed according to actual needs. This embodiment does not improve the drive component, so it will not be described in detail.

[0065] For example, please continue reading Figure 2 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, which are hinged sequentially. When a user lies on the electric bed, the first bed frame 110 roughly corresponds to the user's head and back, the second bed frame 120 roughly corresponds to the user's hips (and can also be called a hip bed frame), the third bed frame 130 roughly corresponds to the user's thighs, and the fourth bed frame 140 roughly corresponds to the user's calves and feet. Two drive units are connected to the first bed frame 110 and the third bed frame 130 respectively. By driving the drive units, the first bed frame 110 and the third bed frame 130 can be lifted, 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; alternatively, another drive unit can be provided to lift the fourth bed frame 140, etc. It is understood that the arrangement of the bed frame 100 and the drive unit is not limited to the above. The bed frame 100 may also be in other forms, such as having only three parts: the first bed frame 110, the second bed frame 120, and the third bed frame 130, or more or fewer parts. The connection between the drive unit and the bed frame 100 may also be different. For example, only one drive unit may be provided that is connected to any part of the bed frame 100 and can drive that part to lift. All of these are achievable by those skilled in the art, and the examples in this embodiment do not constitute an undue limitation on this application.

[0066] For example, Figure 2 This illustrates a state in which the mattress 200 is raised. It is understood that this is merely an example and does not constitute an undue limitation on this application. In some embodiments, after the bed frame 100 is raised, the bed frame 100 and the mattress 200 may also be in other tilted states.

[0067] Here, when the bed frame 100 is raised, the mattress 200 on the bed frame 100 will be raised simultaneously, and the mattress 200 will be raised to an inclined position. Due to gravity, the mattress 200 will slide downwards, and the relative position between the mattress 200 and the bed frame 100 will change, resulting in a part of the mattress 200 bulging or the mattress 200 falling out of the bed frame 100.

[0068] Therefore, in the embodiments of this application, please refer to Figure 3 The bed frame 100 is provided with at least one channel 170. Exemplarily, two channels 170 are provided on the fourth bed frame 140. Also exemplary, the channels 170 on the bed frame 100 can be arranged in groups, with each group including two channels 170 symmetrically arranged in the width direction of the bed frame 100, that is, each group including two channels 170 axially symmetrical along the centerline of the bed frame 100 in the length direction. Of course, it is understood that in other embodiments, the location and number of channels 170 are not limited to the above. For example, one, two, three, five, six, etc., channels 170 can be provided. Furthermore, in other embodiments, channels 170 can also be located in other positions, such as on the second bed frame 120. The examples in this embodiment do not constitute an undue limitation. In addition, the channels 170 can be directly provided on the bed frame 100, or a fixed seat 180 can be provided on the bed frame 100 (see reference...). Figure 9 As shown), a channel 170 is provided on the fixed base 180.

[0069] Here, passage 170 extends through the first side 150 and the second side 160 of the bed frame 100. See also... Figure 4 and Figure 5 Fasteners 700 are provided at each channel 170 position.

[0070] Please see Figure 6 A mating part 600 is provided on the mattress 200, which can be mated to the channel 170 at the aforementioned bed frame 100.

[0071] Please refer to further information. Figure 7 For example, the mattress 200 here has a fastener 400 on the side near the bed frame 100. In normal use, that is, the fastener 400 is provided on the underside of the mattress 200. The fastener 400 is used to connect the connector 500 to the mattress 200, and the connector 500 is provided with the aforementioned mating part 600.

[0072] Please combine Figure 5At least a portion of the mating part 600 can pass through the channel 170 and engage with the fastener 700 at the channel 170, thereby allowing the mattress 200 to fit better against the bed frame 100. The engagement method between the mating part 600 and the fastener 700 can be snap-fit, magnetic connection, or other connection methods, and this embodiment does not impose any undue limitations on them.

[0073] Therefore, through the cooperation of the mating part 600 and the fastener 700, the mattress 200 is restrained, thus preventing the mattress 200 from slipping relative to the bed frame 100. This is especially true when the bed frame 100 is raised, further reducing the slippage of the mattress 200 relative to the bed frame 100. Consequently, due to the reduced displacement, the mattress 200 maintains a better fit with the bed frame 100, making it less prone to bulging or slipping out of the bed frame 100 area. This helps improve user comfort, reduces damage to the mattress 200, and extends its lifespan.

[0074] In some embodiments, during installation, the user first inserts at least a portion of the mating part 600 into the channel 170. The user's hand can be positioned on the second side 160 of the bed frame 100 and apply force to the mating part 600 or the fastener 700 from the second side 160, so that the mating part 600 can engage with the fastener 700. The second side 160 can be the side of the bed frame 100 closest to the ground. After engagement, since the fastener 700 is fixed to the bed frame 100, and the mating part 600 is connected to the mattress 200 via the connector 500 or other means, the engagement connection between the fastener 700 and the mating part 600 can reduce the displacement of the mattress 200 relative to the bed frame 100.

[0075] In the embodiments of this application, the mating part 600 moves from the first side 150 to the second side 160 of the bed frame 100 via the channel 170 and engages with the fastener 700 at the channel 170. However, if the engagement point of the mating part 600 and the fastener 700 were located on the first side 150 of the bed frame 100, i.e., the side of the bed frame 100 closest to the mattress 200, the engagement point of the mating part 600 and the fastener 700 would be obscured by the mattress 200, making it inconvenient for the user to operate the engagement. The arrangement in the embodiments of this application facilitates user operation to connect and disconnect the mating part 600 and the fastener 700.

[0076] Here, the mating parts 600, fasteners 700, and channels 170 are correspondingly arranged; that is, the positions and quantities of the mating parts 600, fasteners 700, and channels 170 correspond one-to-one. For example, please refer to... Figure 8 Here, six channels 170 are provided on the bed frame 100, and fasteners 700 are provided at each channel 170 (please refer to...). Figure 5 (As shown), please refer to the following: Figure 6 The mattress 200 is provided with six corresponding mating parts 600, and each mating part 600 can engage with the fastener 700 at the corresponding channel 170. Of course, it is understood that in other embodiments, these components may not be provided in a one-to-one correspondence. For example, several mating parts 600 may share the same channel 170; several mating parts 600 may be connected to the same fastener 700, etc. The example in this embodiment does not constitute an undue limitation.

[0077] Furthermore, in some embodiments, the spacing between the channels 170 can be set relatively large to better tighten the mattress 200 and conform it to the bed frame 100 via the two spaced-apart mating parts 600. Exemplarily, in Figure 3 In the middle, two channels 170 on the fourth bed frame 100 are spaced apart, for example, close to the opposite left and right sides of the bed frame 100 respectively.

[0078] In some embodiments, the connector 500 can be a steel wire rope, a braided belt, or a nylon belt, etc. For example, the connector 500 can also be a cloth belt made of other materials, or a chain. As a result, the connector 500 has good tensile strength and is not easily deformed, which helps to maintain the positioning of the mattress 200 and reduce the slippage of the mattress 200 relative to the bed frame 100.

[0079] In some embodiments, please refer to Figure 8 The bed frame 100 has channels 170 provided in the area near the feet and / or in the area near the hips. Furthermore, exemplary embodiments are provided in which a second bed frame 120 and a fourth bed frame 140 are also included (see [link to embodiment]). Figure 3 The second bed frame 120 and / or the fourth bed frame 140 may have a channel 170. The position on the mattress 200 that mates with the mating part 600 may roughly correspond to the position of the channel 170, for example, in the area near the hips and feet, but it may also be located further away from the channel 170. The example in this embodiment does not constitute an undue limitation on this.

[0080] In some embodiments, the fastener 700 is movably disposed at the channel 170 to selectively form a first passage and a second passage within the channel 170. For example, see [link to example]. Figure 9 The fastener 700 can be rotatably connected to the channel 170 by means of hinge or pivot connection. Of course, in other embodiments, the fastener 700 can also be movably set in other ways, such as the fastener 700 being detachably installed in the channel 170 or slidably installed in the channel 170 by means of slide rail.

[0081] Here, with the first passage formed, at least a portion of the mating part 600 can pass through the channel 170 along the first passage. For example, please refer to... Figure 9 After the fastener 700 rotates, it at least partially leaves the space within the channel 170, thereby opening the channel 170 and forming a first passage. At this time, the mating part 600 can pass through the channel 170. Here, a portion of the mating part 600 passes through the channel 170. From the orientation of the bed frame 100, the mating part 600 moves from the first side 150 to the second side 160 during this process, that is, it moves from top to bottom in the direction shown in the figure. Of course, it can be understood that in other embodiments, the mating part 600 may also pass entirely through the channel 170, or it may not pass through the channel 170 but only be accommodated within the channel 170. If it is necessary to accommodate the mating part 600 within the channel 170, the rotation direction or the mode of movement of the fastener 700 may differ from the previous method. Figure 9 The states shown may differ; for example, fastener 700 may need to be set to face. Figure 9 The upper side is rotated in the indicated direction to prevent the fastener 700 from obstructing the movement of the mating part 600 when it is received within the channel 170. Furthermore, in some examples, the end face of the fastener 700 near the mating part 600 may be shaped to conform to the bottom edge of the mating part 600 to avoid it during movement.

[0082] With the second passage formed, at least a portion of the mating part 600 cannot pass through the channel 170 along the second passage. (See also...) Figure 10 And please combine Figure 11 As shown, compared to Figure 9 In the shown state, the mating part 600 is moved at least partially into the channel 170 by rotation or other means, thereby blocking part of the first passage and forming a second passage. That is, the second passage is transformed from the first passage due to the obstruction of the mating part 600. At this time, since at least part of the first passage is blocked, the mating part 600, which can pass through the first passage, cannot pass through the second passage, thereby limiting the mating part 600, and forming a mating connection between the mating part 600 and the fastener 700.

[0083] It is understood that the first passage is only partially blocked by the mating part 600 to form the second passage. In some embodiments, the mating part 600 may be configured to almost completely block the first passage, that is, the second passage may be a substantially closed passage, allowing only the connection structure (such as the connector 500) between the mattress 200 and the mating part 600 to pass through. Of course, the example in this embodiment does not constitute an undue limitation.

[0084] In some embodiments, for a better illustration of the working principle of the embodiments of this application, please refer to [the relevant documentation / reference]. Figure 12As shown. Along the axial direction of channel 170, that is... Figure 12 In the direction perpendicular to the paper, the aforementioned first path has a first projection, and the second path has a second projection. Figure 12 Region T1 roughly shows the area range of the first projection, while region T2 roughly shows the area range of the second projection. It is evident that due to the obstruction of at least a portion of the fastener 700, at least a portion of the area of ​​the first projection is blocked, thus forming a smaller second projection.

[0085] Furthermore, along the axial direction of channel 170, the mating portion 600 has a third projection (not shown in the figure). The first projection covers the third projection, so the mating portion 600 can pass through the first passage; however, at least a portion of the third projection extends beyond the range of the second projection, preventing the mating portion 600 from passing through the second passage. Thus, by moving the fastener 700, the state of channel 170 can be selectively switched between the first and second passages. In the first passage state, the mating portion 600 can pass through channel 170; in the second passage state, the mating portion 600 cannot pass through channel 170, thereby achieving selective limiting of the mating portion 600.

[0086] In some embodiments, the fastener 700 is rotatably disposed at the channel 170. Here, by way of example, the rotatable connection position of the fastener 700 and the channel 170 may be approximately at the end of the channel 170 away from the mattress 200, that is, approximately at the bottom end of the channel 170 in actual use.

[0087] Thus, with the first passage formed, at least a portion of the fastener 700 can rotate to the second side 160 of the bed frame 100. The advantage of this arrangement is that the fastener 700 moves towards the side of the bed frame 100 away from the mattress 200, facilitating user operation. Simultaneously, the direction of movement of the fastener 700 is opposite to the direction of movement of the mating part 600 disengaging from the channel 170, making it less likely for the mating part 600 to be released from its position by the fastener 700 and disengage from the channel 170 due to misoperation or other unforeseen external forces, thereby achieving an effective limiting effect.

[0088] Of course, it is understood that in other embodiments, the connection method between the fastener 700 and the bed frame 100 is not limited to the above. The fastener 700 can be connected to the bed frame 100 directly or indirectly, and the opening and closing direction of the fastener 700 is not limited to the above. The examples in this embodiment do not constitute an undue limitation.

[0089] In some embodiments, the fastener 700 is movably disposed at the channel 170 and is switchable between a first state and a second state; in the second state, compared to the first state, at least a portion of the fastener 700 moves into the channel 170 to prevent the mating portion 600 from passing through the channel 170.

[0090] Here, for example, the first state can be the aforementioned state of forming the first pathway, and the second state can be the aforementioned state of forming the second pathway. Of course, the examples in the embodiments of this application do not constitute an undue limitation.

[0091] In some embodiments, the electric bed further includes an elastic element connected between the bed frame 100 and the fastener 700 to give the fastener 700 a tendency to remain in a second state. It is understood that, unless otherwise specified, the connections in this application include both direct and indirect connections where feasible. For example, here, the elastic element may be directly connected between the bed frame 100 and the fastener 700, or indirectly connected between the two, as long as it enables the fastener 700 to have a tendency to remain in a second state or form a second passage.

[0092] In some embodiments, please refer to Figure 13 The mating portion 600 includes a first sub-portion 610 and a second sub-portion 620 connected to each other, with the outer diameter of the second sub-portion 620 being larger than that of the first sub-portion 610. Exemplarily, the outer diameter of the first sub-portion 610 can be set to gradually widen to connect with the second sub-portion 620, thereby improving its appearance and reducing the risk of sharp edges and bumps. Furthermore, the second sub-portion 620 can be set to a generally spherical shape. Of course, in other embodiments, the mating portion 600 can also be square, rhomboid, or other shapes, as long as it is adapted to the channel 170 and the fastener 700. In some embodiments, there may not be a clear dividing line between the first sub-portion 610 and the second sub-portion 620; the portion after the outer diameter reaches its maximum position can be considered as the second sub-portion 620.

[0093] Please see here. Figure 11 With the mating part 600 and the fastener 700 engaged, a portion of the second sub-part 620 is exposed outside the channel 170, specifically in the area located on the second side 160 of the bed frame 100. Alternatively, in other embodiments, either the second sub-part 620 or both the first sub-part 610 and the entire second sub-part 620 may be exposed outside the channel 170, specifically in the area located on the second side 160 of the bed frame 100, allowing the user to observe their position.

[0094] In some embodiments, to reduce impacts and noise that may be generated when the mating part 600 contacts the bed board, the mating part 600 is made of a flexible material or a buffer layer made of a flexible material is provided on the surface of the mating part 600. Exemplarily, the mating part 600 is made of a flexible material such as silicone or rubber, or a buffer layer made of a material such as rubber or silicone is provided on the surface of the mating part 600. It is understood that the buffer layer may cover the entire surface of the mating part 600, or it may only cover a portion of the surface, such as only covering the second sub-part 620 that is easily in contact with other components. Of course, the examples in this embodiment do not constitute an undue limitation on this application.

[0095] In some embodiments, as described above, the mating portion 600 is connected to the mattress 200 via a connector 500. For example, the connector 500 may be a steel wire rope or the like. Again, for example, the connector 500 is mated to the mattress 200, and the connector 500 has opposing first and second ends, each provided with a mating portion 600; a channel 170 is provided on the bed frame 100 corresponding to each mating portion 600.

[0096] Therefore, please combine Figure 6 As shown, two mating parts 600 are installed at both ends of a connector 500, that is, the two mating parts 600 can be connected to the mattress 200 through one connector 500, thereby reducing the number of parts and making the assembly more convenient.

[0097] For example, please continue reading Figure 6 Near the tail end of the mattress 200, the connector 500 can extend along the width direction of the mattress 200, thereby making the distance between the mating portions 600 at both ends relatively large. Of course, the example in this embodiment does not constitute an undue limitation. In other locations or other embodiments, the connector 500 may also extend along the length direction of the mattress 200.

[0098] In some embodiments, a connection structure is provided between the connector 500 and the mating portion 600 to achieve connection between the two. For example, please refer to... Figure 14 One end of the connector 500 is provided with a first stop portion 510, the outer diameter of which is larger than the outer diameter of the connector 500. For example, the first stop portion 510 can be a spherical structure. Of course, in other embodiments, it can also be a cylindrical, polygonal, or other structure. The example in this embodiment does not constitute an undue limitation.

[0099] A first channel 630 and a second channel 640 are provided on the mating part 600. The inner diameter of the second channel 640 is larger than the inner diameter of the first channel 630, and the outer diameter of the first stop portion 510 is larger than the inner diameter of the first channel 630. A portion of the connecting member 500 passes through the first channel 630, and the first stop portion 510 is engaged with the second channel 640, so that the connecting member 500 is connected to the mating part 600. Therefore, the mating part 600 cannot be aligned along... Figure 14 The mating part 600 will not move upward on its own to detach from the connector 500 under normal circumstances due to gravity.

[0100] In some embodiments, as described above, the connector 500 can be connected to the mattress 200 via the fastener 400, thereby connecting the mating part 600, the connector 500, and the fastener 400 in sequence, and then forming a connection between the fastener 400 and the mattress 200.

[0101] For example, please refer to Figure 14 The fixing member 400 has an inner cavity 430 with an opening. An end plug 800 is provided at the opening, and the end plug 800 has a through hole 810 extending through it. In addition, the end plug 800 may be provided with threads for connection with the fixing member 400. Of course, the example in this embodiment does not constitute an undue limitation.

[0102] Here, a locking element 820 can be provided, which engages with the outer end of the through hole 810. The locking element 820 also has an opening that connects to the through hole 810. A portion of the connector 500 passes through the opening of the locking element 820 and enters the through hole 810, engaging with the opening. Alternatively, please refer to... Figure 13 The connector 500 is provided with a second stop portion 520, and a portion of the connector 500 passes through the through hole 810 and the second stop portion 520 is confined within the inner cavity 430 (see...). Figure 14 This forms a mating connection between the connector 500 and the fixing member 400. Of course, in other embodiments, the connector 500 can also be connected to the fixing member 400 in other ways, such as magnetic connection, snap-fit, etc. The example in this embodiment does not constitute an undue limitation.

[0103] In some embodiments, based on the provision of a connector 500 and a fixing member 400, both ends of the connector 500 are exposed outside the inner cavity 430 of the fixing member 400, and each end of the connector 500 is provided with a mating part 600.

[0104] Furthermore, each fastener 400 mates with a corresponding connector 500, and the bed frame 100 is provided with a channel 170 corresponding to the mating part 600 provided on the connector 500.

[0105] For example, at least one fastener 400 is disposed near one end of the mattress 200 in the length direction and extends along the width direction of the mattress 200. Furthermore, simultaneously or individually, at least one fastener 400 is disposed near one end of the mattress 200 in the width direction and extends along the length direction of the mattress 200.

[0106] For example, please see Figure 6 The fastener 400 at one end of the mattress 200 along its length extends along the width of the mattress 200, for example, it can be installed on the aforementioned fourth bed frame 100. Simultaneously, at approximately the middle area at both ends of the mattress 200 along its width, a fastener 400 extending along the length of the mattress 200 is provided, for example, it can be installed on the aforementioned second bed frame 100. Each fastener 400 is fitted with a connector 500, and each connector 500 has mating portions 600 at both ends. Channels 170 are provided on the bed frame 100 corresponding to the position and number of mating portions 600 for mating with the mating portions 600.

[0107] Furthermore, as another example, please refer to Figure 7 The fastener 400 includes a generally tubular fixing tube 410 and a connecting strap 420. The aforementioned inner cavity 430 is located within the fixing tube 410. The connecting strap 500 passes through the fixing tube 410 with both ends protruding outside the fixing tube 410. The two ends of the connecting strap 420 are connected to the mattress 200 by sewing thread or other means, forming a space that is generally contoured to the fixing tube 410 for connecting the fixing tube 410. The fixing tube 410 passes through this space and is connected to the mattress 200. Of course, the example in this embodiment does not constitute an undue limitation, and those skilled in the art can use other methods to connect the fastener 400 to the mattress 200 and the connecting strap 500.

[0108] In some embodiments, the bed frame 100 is provided with channels 170 in the area near the hips and / or near the feet, and the mating parts 600 are provided corresponding to the position and number of channels 170.

[0109] In some embodiments, the mating part 600 is configured in terms of position and number corresponding to the channel 170.

[0110] Furthermore, the bed frame 100 includes a first bed frame 100, a second bed frame 100, a third bed frame 100, and a fourth bed frame 100 arranged sequentially along the length of the bed frame 100, with a passage 170 provided on the second bed frame 100 and / or the fourth bed frame 100; or, the bed frame 100 includes a first bed frame 100, a second bed frame 100, and a third bed frame 100 arranged sequentially along the length of the bed frame 100, with the passage 170 provided on the second bed frame 100 and / or the third bed frame 100.

[0111] Accordingly, see Figures 1 to 17 This application also provides a support pad positioning structure for positioning a first component on a second component, wherein one of the first component and the second component is a support pad and the other is a support frame. For example, the support pad can be the aforementioned mattress 200, and the support frame can be the aforementioned bed frame 100; further examples include a support pad being a seat cushion and a support frame being a recliner, etc. It is understood that this support pad positioning structure is more suitable for support frames that are mechanically driven and can change state, as well as support frames that are manually driven and can change state, or support frames that cannot change state, all of which can achieve a cooperative connection between the support pad and the support frame. Of course, the examples in the embodiments of this application do not constitute an undue limitation.

[0112] The first component has a first side 150 and a second side 160 opposite to each other, and the first component is provided with a channel 170 passing through the first side 150 and the second side 160, and a fastener 700 is also provided at the channel 170; the second component is provided on the first side 150 of the first component, and the second component is provided with a mating part 600.

[0113] Here, at least a portion of the mating part 600 passes through the channel 170 and is connected to the fastener 700.

[0114] In some embodiments, as described above, channel 170 may be disposed on mounting base 180, which may be used for connection to the first component.

[0115] It is understood that for the specific structure, location and mating relationship of the mating part 600, fastener 700 and other components, please refer to the foregoing embodiments. To avoid making this application too lengthy, this application will not elaborate further.

[0116] Example

[0117] Please see Figure 15In use, the user first presses down the fastener 700 to expose enough space in the channel 170 for the mating part 600 to pass through. Then, the mating part 600 is inserted into the channel 170 and moved downwards in the direction shown in the figure. Then, the fastener 700 is rotated back to its original position, so that a portion of the channel 170 is blocked by the fastener 700, thereby preventing the mating part 600 from moving upwards in the direction shown in the figure and disengaging from the channel 170.

[0118] Please see Figure 16 and Figure 17 The tail end of the mattress 200 is connected to the bed frame 100 by fastener 700 and mating part 600, which reduces the slippage of the mattress 200 relative to the bed frame 100. Furthermore, due to the reduced displacement, the mattress 200 fits the bed frame 100 more closely, making it less prone to bulging or slipping out of the bed frame 100. This improves user comfort, reduces damage to the mattress 200, and extends its lifespan.
