Description

TECHNICAL FIELD

[0001] The present application relates to the field of bedding, in particular to a bed. BACKGROUND

[0002] The existing bed includes a base, a mattress arranged above the base, and a backrest arranged at the front edge of the base. The backrest and the mattress are fixed structures. The bed cannot provide comfortable support for the user because the posture of the mattress cannot be adjusted. The overall appearance of the bed remains unchanged because the backrest cannot be adjusted, which easily causes visual fatigue and affects the use experience. SUMMARY

[0003] In order to solve the problems of the prior art, the present application provides a bed. The posture adjusting assembly is arranged to adjust the posture of the mattress. The bed can improve the comfort of the user and provide a channel for the backrest to rise and fall, thereby improving the use experience.

[0004] The present application is achieved by the following way: a bed includes a base and a mattress. The periphery of the base is provided with an upwardly extending annular rim. An assembly cavity is arranged in the annular rim. The mattress is embedded at the cavity opening of the assembly cavity. The middle part of the assembly cavity is provided with a posture adjusting assembly for supporting the mattress. The front part is provided with a liftable backrest. The mattress is moved backward by the posture adjusting assembly to form a channel for the backrest to rise and expose. The posture adjusting assembly for adjusting the posture of the mattress is arranged in the assembly cavity. The channel for the backrest to rise and fall is formed by moving the mattress backward. The backrest can be switched between the hidden station and the use station. The comfort of leaning and the appearance of the bed are improved. The posture of the mattress is adjusted to provide comfortable support for the user. The different requirements of the user for the posture of the mattress in different use scenarios are met. The use experience is improved.

[0005] As a preferred embodiment, the mattress is switched between the initial posture in which the top surface periphery of the mattress is flush with the top surface of the annular rim, and the use posture in which the mattress is moved backward to form the channel. The posture adjusting assembly is used to drive the mattress to switch between the initial posture and the use posture. When the mattress is in the initial posture, the top surface periphery of the mattress is flush with the corresponding section of the top surface of the annular rim. The backrest in the hidden station is matched to form a bed with a flat top surface. The appearance characteristics of the bed are changed to eliminate the aesthetic fatigue of the user and improve the appearance.

[0006] As preferred, the top surface of the annular rim is inclined with the front higher than the rear, the posture adjusting assembly comprises a translation part and a swing part, the swing part drives the rear part of the mattress to be raised upward and obtains a retreat space above the rear edge section of the annular rim for the rear movement of the mattress. The top surface of the annular rim is set to be inclined with the front higher than the rear, so that the rear edge of the mattress can be higher than the rear edge section of the annular rim after being raised by the swing, which facilitates the rear movement of the mattress and ensures that the channel for the backrest lifting can be formed between the front edge of the mattress and the front edge section of the annular rim when the mattress is moved rearward to the position.

[0007] As preferred, the posture adjusting assembly comprises a lower support fixed to the bottom wall of the assembly cavity, the translation part comprises a middle support capable of translating forward and backward along the lower support and a first push rod driving the middle support to translate, and the swing part comprises an upper support swingably connected to the middle support and a second push rod driving the upper support to swing and vertically arranged. The lower support is fixed to the bottom wall of the assembly cavity and effectively supports the middle support and the upper support. The middle support can be driven by the first push rod to move forward and backward together with the upper support, and the upper support can be driven by the second push rod to swing, so that the mattress can be simultaneously adjusted to translate forward and backward and to swing by the posture adjusting assembly, thereby enabling the mattress to switch between the use posture and the initial posture.

[0008] As preferred, the top surface of the lower support is provided with first guide rails arranged in the forward and backward direction, the bottom of the middle support is provided with first sliding blocks matched with the first guide rails, the first guide rails are arranged in the forward and backward direction of the bed, and the middle support is installed on the first guide rails through the first sliding blocks, which not only supports the middle support and its upper components, but also guides the middle support to move forward and backward, thereby driving the mattress to translate forward and backward.

[0009] As preferred, the fixed end of the first push rod is fixed to the lower support, the movable end is fixed to the middle support, the extension direction of the first push rod is consistent with the sliding direction of the middle support, and the axis of the first push rod is arranged in the forward and backward direction, so that the movable end of the first push rod can drive the middle support to move forward and backward, which effectively improves the transmission efficiency between the first push rod and the middle support and prevents the first sliding block and the first guide rail from being stuck.

[0010] As preferred, the middle part of the top surface of the middle support extends upward to form a lower support seat, the middle part of the bottom surface of the upper support extends downward to form an upper support seat, and the upper support seat and the lower support seat are hingedly connected through a rotating shaft. The upper support seat and the lower support seat are partially overlapped and connected through the rotating shaft, and the axis of the rotating shaft is arranged in the transverse direction of the bed, so that the front edge and the rear edge of the mattress are alternately lifted when the mattress swings around the rotating shaft, thereby adjusting the angle between the top surface of the mattress and the horizontal plane, which meets the adjustment requirements of the user for the posture of the mattress and effectively improves the use comfort of the mattress.

[0011] As preferred, the fixed end of the second push rod is hinged with the rear edge of the middle support, and the movable end is hinged with the rear edge of the upper support. Since the middle support and the upper support are connected through the rotating shaft, when the upper support swings around the rotating shaft, the rear edge of the upper support will shift forward and backward relative to the rear edge of the middle support. The two ends of the second push rod are hinged between the upper support and the middle support, so that the second push rod can swing forward and backward around the rear edge of the middle support, thereby offsetting the forward and backward swing of the rear edge of the upper support, and ensuring that the second push rod can drive the upper support to swing around the rotating shaft through the extension and contraction.

[0012] As preferred, the mattress comprises a bed support and a cushion body which are connected in a flush manner, and a receiving groove is arranged in the middle of the top surface of the bed support for embedding the cushion body. The bottom surface of the bed support is provided with a supporting plate, and the bottom surface of the supporting plate is provided with a clamping groove which can be inserted and clamped with the top of the posture adjusting assembly. The mattress has a split structure, which can not only facilitate the independent production and processing of each part to reduce the production cost, but also reduce the disassembly difficulty by reducing the weight of each part, thereby facilitating the maintenance and use. In addition, since the cushion body and the bed support are in a split structure, the user can replace the cushion body according to the needs, so as to obtain a cushion body that meets the user's sleeping habits, thereby effectively improving the use experience.

[0013] As preferred, the front part of the assembly cavity is provided with a lifting assembly for driving the backrest to move. The lifting assembly comprises a third push rod for driving the backrest to lift, a second guide rail arranged in the same direction as the third push rod, and a second sliding block arranged in the backrest and matched with the second guide rail. The second push rod drives the backrest to lift and switch between a hidden station completely hidden in the assembly cavity and a use station exposed by passing through the channel. The lifting assembly is used for lifting and adjusting the backrest between the hidden station and the use station. The third push rod can provide driving force for the lifting of the backrest, and the second guide rail and the second sliding block can guide the lifting of the backrest, so as to ensure that the backrest moves along a predetermined path and prevent the backrest from being scratched or clamped with adjacent parts. By reducing the size of the channel, the space utilization efficiency in the base can be improved.

[0014] As preferred, a through hole is arranged on the side wall of the annular surrounding edge, and the side part of the assembly cavity is provided with a functional part which can pass through the through hole and switch between the hidden station and the use station by the driving of the extension and contraction assembly. The through hole can provide hidden space for the functional part, effectively reducing the space occupied by the functional part, and also provide exposed space for the functional part, so as to ensure that the functional part can exert its own function and improve the use experience.

[0015] As preferred, the telescopic assembly comprises a fourth push rod fixed to the bottom of the assembly cavity by the support, the fourth push rod is telescopic along the axis of the through hole and drives the functional part to switch between the hidden working position, which is completely hidden in the base and is flush with the peripheral edge of the outer port of the through hole, and the use working position, which is exposed to the through hole. The fourth push rod drives the functional part to move telescopically between the hidden working position and the use working position. When the functional part is in the use working position, the functional part is exposed to the outer port of the through hole, which is convenient for use; when the functional part is in the hidden working position, the functional part is hidden in the through hole, and the outer end surface of the fourth push rod away from the functional part blocks the outer port of the through hole, which ensures that the side wall of the base remains flat and improves the aesthetics.

[0016] As preferred, the through hole is provided with a third guide rail for guiding the sliding of the functional part along the preset path. The third guide rail is arranged along the axis of the through hole, and the functional part slides along the third guide rail and can reliably switch between the use working position and the hidden working position through the through hole.

[0017] As preferred, the functional part is a pedal, and the through hole is arranged on the bottom of the side edge section of the annular surrounding edge. The pedal arranged on the side of the base is telescopic, which can ensure the aesthetics of the side of the base by switching the pedal to the hidden working position, and can provide a stepping area for users to get on and off the bed by switching the pedal to the use working position, and can reduce the step height of the user when getting on and off the bed by increasing the pedal, which ensures the safety of the user when getting on and off the bed and improves the use experience.

[0018] The functional part is a drawer, the through hole is arranged on the upper part of the side edge section of the annular surrounding edge, and the fourth push rod and the drawer are connected through an inclined connecting rod. The drawer arranged on the side of the base is telescopic between the use working position and the hidden working position, which can provide a storage space for users, increase the activity space of the bed, facilitate the movement of the user, and reduce the number and volume of the bed and its supporting articles for convenient transportation. The inclined connecting rod can transmit the pushing force between the fourth push rod and the drawer, and can be used to coordinate the height difference between the fourth push rod and the drawer to ensure that the drawer is stably pushed and displaced.

[0019] The posture adjusting assembly arranged in the assembly cavity can adjust the posture of the mattress, which can form a channel for the backrest to switch between the hidden working position and the use working position by driving the mattress to retreat, improve the leaning comfort, improve the aesthetics of the bed, and provide comfortable support for the user by adjusting the posture of the mattress to meet the differentiated requirements of the user for the posture of the mattress in different use scenarios, thereby improving the use experience.

The posture of the mattress 2 is adjusted by the posture adjusting assembly 4 in the assembly cavity, so that the bed can form a channel 6 for the backrest 5 to rise and fall by adjusting the posture of the mattress 2, which can hide the backrest 5 and the channel 6 to make the bed have a flat top surface, effectively improve the aesthetics, provide users with a different visual experience from traditional beds, and improve the interest and experience of use, and can also provide users with comfortable support in different use scenarios by adjusting the posture of the mattress 2, and can also provide users with comfortable leaning in different use scenarios by adjusting the height of the backrest 5, and improve the comfort of use.

[0037] In this embodiment, the mattress 2 is switched between the initial posture in which the top surface of the mattress 2 is flush with the top surface of the annular rim 3 and the use posture in which the mattress 2 retreats to form the channel 6 by the posture adjusting assembly 4. Specifically, the top surface of the annular rim 3 is inclined with the front higher than the back, when the mattress 2 is in the initial state, the mattress 2 is embedded in the assembly cavity (as shown in Figure 3 The top surface of the mattress 2 is inclined, the top surface of the mattress 2 is matched and connected with the top surface of the annular rim 3, the backrest 5 is hidden in the assembly cavity, the gap between the mattress 2 and the annular rim 3 is eliminated to ensure that the bed has a flat and continuous top surface, so that the bed has a visual effect different from existing beds, thereby improving the aesthetics of the bed and decorating the bedroom. When the user needs to use the bed, the bed can be deformed to the use posture according to the user's needs, the posture of the mattress 2 is adjusted under the drive of the posture adjusting assembly 4, which can provide comfortable support for the user, and can also separate the front edge of the mattress 2 from the front edge of the annular rim 3 and form a channel 6 connected with the assembly cavity, so that the backrest 5 in the assembly cavity can be lifted upward and exposed through the channel 6, providing comfortable leaning for the user.

[0038] In use, the bed mattress 2 and the backrest 5 cooperate to deform the bed according to the use requirement. When the user needs to lie down, the bed mattress 2 is switched from the initial posture to the use posture, the first push rod 9 and the second push rod 11 are operated simultaneously, the second push rod 11 extends along the axial direction and drives the rear edge of the bed mattress 2 to be raised, so that the height difference between the rear edge of the bed mattress 2 and the rear edge section of the annular surrounding edge 3 provides a retreat space for the rear movement of the bed mattress 2, the first push rod 9 extends along the axial direction and drives the bed mattress 2 to move rearward, so that the bed mattress 2 can move rearward by using the retreat space, and then the channel 6 vertically aligned with the backrest 5 is formed between the front edge of the bed mattress 2 and the front edge section of the annular surrounding edge 3, after the channel 6 is formed, the backrest 5 is switched from the hidden position to the use position by the driving of the third push rod 20. After the deformation is completed, the top surface of the bed mattress 2 is arranged horizontally to effectively support the user, and the backrest 5 is exposed to the upper end of the channel 6 to facilitate the user to lean on it. When the user does not need to use the bed, the backrest 5 is lowered into the assembly cavity by the driving of the third push rod 20, the bed mattress 2 is switched from the use posture to the initial posture, the bed mattress 2 is completely embedded in the cavity opening of the assembly cavity, and the top surface of the bed mattress 2 is matched and connected with the top surface of the annular surrounding edge 3, so that the bed has a flat top surface.

[0039] In the embodiment, the posture adjusting assembly 4 includes a translation part and a swing part (as shown in Figure 4 The swing part drives the rear part of the bed mattress 2 to be raised upward and obtains the retreat space for the rear movement of the bed mattress 2 above the rear edge section of the annular surrounding edge 3. The translation part is used to drive the bed mattress 2 to move forward and backward, and the swing part is used to drive the bed mattress 2 to swing, and the posture of the bed mattress 2 is adjusted by independently controlling the translation part and the swing part. When the bed mattress 2 is in the initial posture, the bed mattress 2 cooperates with the annular surrounding edge 3 and has good appearance, the bed mattress 2 can have multiple use postures, so that the user can obtain different use experiences according to the requirement, and the use comfort of the user in different scenes is effectively improved. The translation part and the swing part can be adjusted simultaneously or at different times, and the adjustment range of the translation part and the swing part can be adjusted according to the requirement to obtain different use postures, which should all be regarded as the specific embodiments of the embodiment.

[0040] In the embodiment, the translation part is used to drive the bed mattress 2 to move forward and backward. The posture adjusting assembly 4 includes a lower support 7 fixed to the bottom wall of the assembly cavity (as shown in Figure 6The translation part includes a middle support 8 that can translate forward and backward along the lower support 7 and a first push rod 9 that drives the middle support 8 to translate, the fixed end of the first push rod 9 is fixedly connected with the lower support 7, the movable end is fixedly connected with the middle support 8, the extension direction of the first push rod 9 is consistent with the sliding direction of the middle support 8, and the first push rod 9 can apply a force along the sliding direction of the first guide rail 12 to the middle support 8. Specifically, the top surface of the lower support 7 is provided with two first guide rails 12 that are parallel to each other and arranged in the forward and backward directions, and the bottom of the middle support 8 is provided with two first sliding blocks 13 that are arranged correspondingly to the first guide rails 12, the first sliding blocks 13 slide along the corresponding first guide rails 12 and guide the middle support 8 to translate forward and backward, so that the upper support 10 and the mattress 2 are synchronously translated.

[0041] In the embodiment, the swinging part includes an upper support 10 that is swingably connected to the middle support 8 and a second push rod 11 (as shown in the figure) that drives the upper support 10 to swing and is arranged vertically. Figure 5 The middle part of the top surface of the middle support 8 extends upward to form a lower support 14, the middle part of the bottom surface of the upper support 10 extends downward to form an upper support 15, and the upper support 15 and the lower support 14 are hingedly connected through a rotating shaft, which not only ensures that the upper support 10 and the middle support 8 have a space for the upper support 10 to swing and adjust, effectively increases the swinging range of the upper support 10, and facilitates the posture adjustment of the mattress 2, but also ensures that the upper support 10 can be synchronously adjusted forward and backward with the middle support 8, and ensures that the mattress 2 can receive the driving force for swinging and translating. The fixed end of the second push rod 11 is hingedly connected to the rear edge of the middle support 8, and the movable end is hingedly connected to the rear edge of the upper support 10, so that the axis of the second push rod 11 can swing with the bottom end as the center, effectively eliminating the forward and backward deviation of the upper support 10 when swinging, and ensuring that the driving force formed by the extension of the second push rod 11 can smoothly push the upper support 10 to swing.

[0042] In the embodiment, the front part of the base 1 is provided with a lifting assembly that drives the backrest 5 to switch between the hidden position and the use position. The lifting assembly drives the backrest 5 to switch between the hidden position and the use position, which not only improves the aesthetics of the bed by hiding the backrest 5, but also meets the differentiated needs of users by adjusting the height of the backrest 5, improves the leaning comfort, and improves the use experience.

[0043] In the embodiment, the lifting assembly includes a third push rod 20 (as shown in the figure) arranged below the backrest 5. Figure 7The third push rod 20 is telescopic and drives the backrest 5 to switch between the hidden position and the use position. The lifting assembly includes a second guide rail 21 fixed to the base 1, and the backrest 5 is provided with a second sliding block 22, and the backrest 5 slides along the second guide rail 21 through the second sliding block 22, so that the backrest 5 can reciprocate along the preset path. The bottom end of the third push rod 20 is fixed to the base 1 through a fixed seat, so that the telescopic direction of the third push rod 20 is consistent with the preset movement path of the backrest 5. During installation, the second guide rail 21 and the bottom of the third push rod 20 are fixed to the base 1, ensuring that the guide section of the second guide rail 21 and the telescopic direction of the third push rod 20 are parallel to each other, which further ensures that the backrest 5 can slide along the guide section under the drive of the third push rod 20, effectively reducing the resistance when the backrest 5 slides, and effectively reducing the space requirement for the lifting of the backrest 5, preventing scratching and clamping with the surrounding components.

[0044] In the embodiment, the second guide rail 21 is two and is arranged on both sides of the backrest 5, and the third push rod 20 is arranged between the second guide rails 21, which ensures that the backrest 5 can be stressed in the middle and smoothly lifted, and also ensures that both sides of the backrest 5 can be guided by the corresponding second guide rails 21, ensuring that the backrest 5 maintains a stable posture during lifting, and can be fixed in position through the second guide rails 21 after the backrest 5 is lifted into position, effectively bearing the leaning force from the user, providing leaning support for the user.

[0045] In the embodiment, the second guide rail 21 includes a guide section arranged parallel to the telescopic direction of the third push rod 20 and a fixed section fixed to the base 1. The fixed section of the second guide rail 21 is horizontally arranged, ensuring that the fixed section can be tightly attached to the top surface of the base 1 and fixed through fasteners, ensuring the position of the guide section is fixed, providing stable support for the lifting of the backrest 5. The guide section is used to guide the sliding of the second sliding block 22, and the guide section can be arranged obliquely, which facilitates the oblique lifting of the obliquely arranged backrest 5, effectively reduces the cross-sectional size of the lifting channel 6 of the backrest 5, and also effectively reduces the thickness of the backrest 5, facilitating the hiding of the backrest 5. The fixed section is arranged front-to-back, effectively improving the front-to-back anti-toppling performance of the second guide rail 21.

[0046] In the embodiment, the backrest 5 comprises a body and a cover plate covering the rear wall of the body, the rear wall of the body is provided with a recess formed by a recess for mounting the second sliding block 22, the bottom wall of the recess is provided with an opening for passing the second guide rail 21, the second guide rail 21 is inserted into the recess through the opening and is in sliding fit with the second sliding block 22. The backrest 5 is in a split structure, in the installation, first, the second sliding block 22 is installed in the recess, then, the second sliding block 22 is sleeved on the guide section of the second guide rail 21, finally, the cover plate is covered on the rear wall of the body, which not only ensures that the backrest 5 can be sleeved on the second guide rail 21 through the opening provided on the bottom wall of the backrest 5 and ensures that the second sliding block 22 can slide along the second guide rail 21, but also can shield the second sliding block 22 and the second guide rail 21 by the cover plate, thereby improving the appearance.

[0047] In the embodiment, the base 1 is provided with an annular surrounding edge 3, the front part of the assembly cavity forms a space for hiding the backrest 5, the mattress 2 is withdrawn and the passage 6 is opened, and the backrest 5 can be switched between a use position exposed to the passage 6 and a hidden position completely hidden in the assembly cavity.

[0048] In the embodiment, the mattress 2 is precisely displaced by the limit switch, the base 1 is provided with a plurality of limit switches matched with the posture adjusting assembly 4, the first push rod 9 drives the middle support 8 to translate and stops running after triggering the corresponding limit switch. The second push rod 11 drives the upper support 10 to swing and stops running after triggering the corresponding limit switch. The limit switch can be triggered when the middle support 8 drives the mattress 2 to move to the use posture or the initial posture and respectively controls the corresponding first push rod 9 and the second push rod 11 to stop running.

[0049] In the embodiment, the backrest 5 is precisely displaced by the limit switch. Specifically, the second guide rail 21 is provided with a limit switch, when the backrest 5 is lifted and the second sliding block 22 touches the limit switch, the third push rod 20 stops running and positions the backrest 5 at the use position or the hidden position. The limit switch can be triggered after the backrest 5 is moved to the position and controls the third push rod 20 to stop running, thereby controlling the lifting of the backrest 5. The limit switch is arranged at the end of the second guide rail 21 and is used to assist the backrest 5 to control the third push rod 20 to stop running when the backrest 5 is moved to the hidden position or the use position, thereby ensuring that the backrest 5 is precisely moved.

[0050] In actual operation, the control box is arranged in the assembly cavity, which is used to receive signals from the limit switch and the user and ensures that each movable part of the bed is precisely adjusted within the preset movable range.

[0051] Embodiment two:

[0052] Compared with the first embodiment, the embodiment provides another structure of the bed.

[0053] As Figure 8 shown, the mattress 2 comprises a bed support 16 and a cushion body 17 flushly connected at the top surface, the middle of the top surface of the bed support 16 is provided with a receiving groove for embedding the cushion body 17, the bottom surface of the bed support 16 is provided with a supporting plate 18, the bottom surface of the supporting plate 18 is provided with a clamping groove 19 which can be inserted and clamped with the top of the posture adjusting assembly 4. The mattress 2 is arranged in a split structure comprising the bed support 16 and the cushion body 17, so that the mattress 2 can be disassembled in parts, which can not only replace the cushion body 17 alone to meet the user's requirement for different hardness, but also reduce the difficulty of maintenance and improve the user experience by disassembling the mattress 2 in parts.

[0054] In this embodiment, the mattress 2 comprises a bed support 16 and a cushion body 17 arranged on the bed support 16. Each part of the mattress 2 can be installed on the base 1 one by one, which not only facilitates disassembly by reducing the weight of each part, but also facilitates processing and production. Specifically, first, the bed support 16 with a filling layer is installed on the upper bracket 10 of the posture adjusting assembly 4 in the base 1 through the supporting plate 18, and then the cushion body 17 is embedded in the receiving groove. The bed support 16 and the cushion body 17 are installed on the base 1 in steps, which not only reduces the difficulty of disassembly, facilitates assembly and maintenance, but also plays a role in shielding the assembly cavity to prevent the posture adjusting assembly 4 from affecting the aesthetic appearance due to exposure.

[0055] In this embodiment, the bottom surface of the bed support 16 is provided with a supporting plate 18, and the bed support 16 is connected with the upper bracket 10 through the supporting plate 18. The supporting plate 18 is attached to the bottom surface of the bed support 16 from bottom to top and is fixed by fasteners, so that the supporting plate 18 and the bed support 16 are fixed and linked, thereby facilitating the posture adjusting assembly 4 to drive the mattress 2 to adjust and position the posture through the supporting plate 18.

[0056] In this embodiment, the bottom surface of the supporting plate 18 is provided with a clamping groove 19, the vertical projection size of the clamping groove 19 matches the vertical projection size of the upper bracket 10, and the two opposite side walls of the clamping groove 19 have different heights, specifically, the outer edge side wall of the clamping groove 19 is higher than the inner edge side wall. During installation, first, the bed support 16 is moved above the posture adjusting assembly 4 with the clamping groove 19 exposed downward, and then the bed support 16 is overlapped on the posture adjusting assembly 4 from top to bottom, so that the clamping groove 19 is vertically sleeved on the upper bracket 10. During the sleeving process, the upper bracket 10 will first contact the bottom of the outer edge side wall of the clamping groove 19, and under the guiding action of attachment, it is ensured that the upper bracket 10 can contact the inner edge side wall of the clamping groove 19, which plays a role in vertical guiding and aligning the clamping groove 19 and the upper bracket 10, effectively reducing the assembly difficulty and improving the insertion accuracy.

[0057] In the embodiment, the upper support 10 is formed by splicing and fixing the square-sectioned rods, the vertical cross-sectional profile of the clamping groove 19 matches the radial cross-sectional profile of the rods, and after installation, the outer edge side wall, inner edge side wall and top wall of the upper support 10 match and abut against the outer edge side wall, inner edge side wall and top wall of the clamping groove 19, thereby ensuring that the supporting plate 18 can be driven by the upper support 10 to realize horizontal and upward synchronous linkage, and ensuring that the mattress 2 can be translated and swung and other posture adjusting actions are driven by the posture adjusting assembly 4, and at the same time, the mattress 2 uses its own gravity to ensure that the clamping groove 19 is reliably sleeved on the upper support 10, thereby preventing the clamping groove 19 from being separated from the upper support 10 due to upward jumping of the mattress 2.

[0058] In the embodiment, the upper support 10 is in a day-shaped structure, including an outer frame and a reinforcing rod bridging between opposite edges, thereby ensuring that the structural strength of the upper support 10 meets the requirements of supporting the mattress 2 and driving the mattress 2 to adjust the posture. In addition, the upper support 10 can also be provided in other shapes, such as a field-shaped structure or an eye-shaped structure, which should all be considered as specific embodiments of the present application.

[0059] In the embodiment, the top surface of the bed support 16 is provided with a receiving groove, and the wall surface of the receiving groove is provided with a filling layer. During installation, the cushion body 17 is embedded into the receiving groove from top to bottom, and the side wall and bottom wall of the cushion body 17 abut against the side wall and bottom wall of the receiving groove through the corresponding filling layer, so that the top surface of the cushion body 17 is smoothly connected with the top surface of the bed support 16. After installation, the receiving groove and the cushion body 17 are provided with the filling layer, the filling layer fills the gap between the inner wall of the receiving groove and the outer wall of the cushion body 17 through its own deformation, and the top surface of the filling layer, the top surface of the cushion body 17 and the top surface of the bed support 16 form a smooth and continuous plane, which not only positions the cushion body 17, but also ensures that the mattress 2 has a smooth top surface, thereby effectively improving the appearance of the bed.

[0060] In the embodiment, the mattress 2 includes a skin layer that completely covers the top surface of the bed support 16 and the top surface of the cushion body 17. The skin layer is an integral structure and can completely cover the top surface of the mattress 2, which not only effectively blocks the gap between the top surface of the bed support 16, the top surface of the filling layer and the top surface of the cushion body 17, thereby ensuring that the top surface of the mattress 2 has a uniform visual effect and improving the appearance, but also positions the cushion body 17, thereby ensuring that the top surface of the mattress 2 remains smooth and improving the lying comfort.

[0061] The other structures and effects of the bed in the embodiment are the same as those in Embodiment One, and will not be described again.

[0062] Embodiment Three

[0063] Compared with Embodiment One and Embodiment Two, the present embodiment provides another structure of a bed.

[0064] AsFigure 9 As shown, the side wall of the annular surrounding edge 3 is provided with a through hole 23, and the side of the assembly cavity is provided with a function part which can pass through the through hole 23 and switch between the hidden position and the use position under the drive of the telescopic assembly. The function part is a drawer 28.

[0065] In the embodiment, the side of the base 1 is provided with the drawer 28 which is driven by the telescopic assembly to switch between the use position and the hidden position. The telescopic assembly is arranged to drive the drawer 28 to move accurately between the use position and the hidden position, so that the drawer 28 in the use position can be used to place and take articles, and the drawer 28 can be switched to the hidden position to reduce the space occupied by the drawer 28 around the bed, so as to provide a spacious space for the user to pass through, and the number of articles matched with the bed can be reduced to facilitate the carrying and improve the use experience.

[0066] In the embodiment, the telescopic assembly includes a fourth push rod 25 arranged in the assembly cavity (as shown). Figure 10 The fourth push rod 25 drives the drawer 28 to switch between the hidden position in which the drawer 28 is completely hidden in the base 1 and the use position in which the drawer 28 is exposed outside the base 1. Specifically, the fourth push rod 25 is arranged in a horizontal posture at the bottom of the assembly cavity to reserve space for the installation of the mattress 2 at the top of the assembly cavity. The fourth push rod 25 is arranged in a horizontal posture at the bottom of the assembly cavity, so that the top of the assembly cavity is empty and convenient for accommodating the mattress 2, which not only ensures that the mattress 2 can be inserted at the cavity opening of the assembly cavity and reserves space for adjusting the posture of the mattress 2, but also prevents the fourth push rod 25 from being stuck due to the interference with the mattress 2, so as to ensure the smooth telescopic movement of the fourth push rod 25.

[0067] In the embodiment, the upper part of the side wall of the assembly cavity is provided with a through hole 23, and the fourth push rod 25 drives the drawer 28 to reciprocate along the axis of the through hole 23 through the inclined connecting rod 29. The through hole 23 is arranged above the front part of the side wall of the base 1, which shortens the distance between the drawer 28 and the hands of the user and facilitates the user to take and place articles from the drawer 28, thereby improving the convenience of use. Since there is a height difference between the through hole 23 and the fourth push rod 25, and the telescopic direction of the drawer 28 is consistent with the telescopic direction of the fourth push rod 25, the inclined connecting rod 29 is arranged between the movable end of the fourth push rod 25 and the drawer 28 to realize transmission, which not only can be fixed to the movable end and the drawer 28 through the ends with height difference at both ends of the connecting rod 29, but also can realize the smooth transmission of the pushing force through the connecting rod 29, so as to ensure that the drawer 28 can smoothly translate along the preset path to switch between the use position and the hidden position.

[0068] In the embodiment, the bottom wall of the assembly cavity is provided with a support 24, and the fixed end of the fourth push rod 25 is fixedly connected to the support 24, so that the extension direction of the movable end of the fourth push rod 25 is parallel to the axis of the through hole 23. The bottom end of the support 24 is arranged on the bottom wall of the assembly cavity, and the top is fixedly connected to the fixed end of the fourth push rod 25. The movable end of the fourth push rod 25 is fixedly connected to the bottom end of the connecting rod 29. The top end of the support 24 is arranged at the same height as the bottom end of the connecting rod 29, so that the fourth push rod 25 can apply a horizontal pushing force to the drawer 28 through the connecting rod 29 in a horizontal posture. The fourth push rod 25 always maintains a horizontal posture during extension and retraction, preventing the fourth push rod 25 from contacting the mattress 2.

[0069] In the embodiment, when the drawer 28 is in the hidden position, the outer end surface of the drawer 28 is flushly connected to the outer port peripheral edge of the through hole 23. The axial projection profile of the through hole 23 matches the axial projection profile of the drawer 28 along the through hole 23, which not only ensures that the drawer 28 can be extended and retracted through the through hole 23, but also improves the appearance by reducing the gap between the drawer 28 and the outer port peripheral edge of the through hole 23. Specifically, when the drawer 28 is in the hidden position, the end surface of the drawer 28 facing away from the fourth push rod 25 can be flushly connected to the outer port peripheral edge of the through hole 23. When the drawer 28 is in the use position, the outer wall of the drawer 28 can be connected to the outer port peripheral edge of the through hole 23, preventing the fourth push rod 25 and other components in the through hole 23 from being exposed.

[0070] In the embodiment, the inner port of the through hole 23 is provided with a seat body with a third guide rail 26, and the bottom of the drawer 28 is provided with a sliding groove matched with the third guide rail 26, so that the drawer 28 can be extended and retracted along the third guide rail 26 under the drive of the fourth push rod 25. The seat body is two and is arranged on the bottom edge of the inner port of the through hole 23. The seat body is provided with third guide rails 26 arranged parallel to each other. The sliding groove is sleeved on the third guide rail 26 and slides along the third guide rail 26. The third guide rail 26 can not only guide the drawer 28 to extend and retract along the axial direction of the through hole 23, but also support the drawer 28, preventing the drawer 28 from being scratched and stuck with the inner wall of the through hole 23, and ensuring smooth translation of the drawer 28.

[0071] In the embodiment, a limiting plate is arranged in the assembly cavity. A guide groove is formed in the top surface of the limiting plate, and the bottom surface of the connecting rod 29 is formed by being raised downward to form a sliding piece that can slide along the guide groove. The limiting plate is arranged in the side area adjacent to the through hole 23 of the assembly cavity. A guide groove is formed in the top surface of the limiting plate, which is arranged in the same direction as the translation path of the drawer 28. The height of the slot of the guide groove matches the height of the bottom end of the connecting rod 29. The sliding piece is inserted into the guide groove and guides the connecting rod 29 to slide along the guide groove. By limiting the deviation of the connecting rod 29, it can effectively transmit the pushing force and effectively improve the transmission efficiency of the extension and retraction assembly, and improve the use reliability by reducing failures.

[0072] In the embodiment, limit switches are arranged on the end portions of the guide grooves, and the bottom surface of the connecting rod 29 is formed with a trigger member that can be in contact with the limit switches. The limit switches can be triggered by the trigger member to control the fourth push rod 25 to stop running. The limit switches are multiple, and can control the connecting rod 29 to be positioned at a specified position, thereby ensuring that the drawer 28 can be accurately positioned at the use position or the hidden position.

[0073] In the embodiment, the two side edge sections of the annular surrounding edge 3 are arranged with the drawers 28 that can be exposed or hidden. The two drawers 28 arranged on the two sides of the base 1 can increase the number of storage cavities, and facilitate the user to take or place the articles in the lying position, thereby effectively improving the use convenience. The fourth push rod 25 can perform the extension or retraction action upon receiving the instruction from the user. The instruction can come from the button, the sensor or the mobile terminal, which should all be regarded as the specific embodiments of the present application.

[0074] In the embodiment, the drawer 28 comprises a shell and a core body arranged in the shell. The core body is plug-inly installed in the shell. The core body is plug-inly arranged in the shell, and the core body is arranged with a storage cavity with an exposed top portion. Preferably, the core body is arranged on the rear side wall of the shell. When the drawer 28 is switched to the use position, the rear wall of the shell is exposed, facilitating the plug-in switching of the core body, so as to facilitate the user to take or place the articles in the storage cavity. When the drawer 28 is switched to the hidden position, the rear wall of the shell is completely hidden in the through hole 23, ensuring that the outer end surface of the shell is smoothly connected with the outer end portion of the through hole 23, thereby improving the appearance of the side wall of the base 1. In addition, the drawer 28 comprises a shell with an open top portion and a cover plate covering the open top portion. When the drawer 28 is moved to the use position, the cover plate is entirely exposed to the base 1 and can be flipped to be opened or closed. This can ensure that the user can take or place the articles when the drawer 28 is in the use position, and can also ensure that the drawer 28 has good appearance when the drawer 28 is in the hidden position, which should also be regarded as the specific embodiment of the present application.

[0075] The other structures and effects of the bed in the embodiment are the same as those in the first embodiment and the second embodiment, and will not be described herein again.

[0076] Embodiment Four

[0077] Compared with the first embodiment and the second embodiment, the present embodiment provides another structure of a bed.

[0078] As shown in Figure 11 The side wall of the annular surrounding edge 3 is arranged with a through hole 23. The side portion of the assembly cavity is arranged with a functional member that can pass through the through hole 23 and be switched between the hidden position and the use position under the driving of the extension and retraction assembly. The functional member is a pedal 27.

[0079] In the embodiment, the side of the base 1 is provided with a pedal 27 driven by a telescopic assembly, so that the pedal 27 can be switched between a use position and a hidden position. By arranging the telescopic assembly to drive the pedal 27 to move accurately between the use position and the hidden position, the pedal 27 located in the use position can provide a stepping area for the user to get on and off the bed, effectively improving the safety of getting on and off the bed and the use experience, and the pedal 27 can be switched to the hidden position to improve the appearance of the side wall of the base 1.

[0080] In the embodiment, the telescopic assembly includes a fourth push rod 25 arranged in the assembly cavity, which drives the pedal 27 to be switched between a hidden position fully hidden in the base 1 and a use position exposed to the base 1. The fourth push rod 25 includes a fixed end and a movable end, and the movable end can reciprocate along the axis of the fourth push rod 25 to drive the pedal 27 to switch between the use position and the hidden position along a preset path.

[0081] In the installation, the bottom of the assembly cavity is provided with a support 24, and the fixed end of the fourth push rod 25 is fixed to the support 24, so that the fourth push rod 25 drives the pedal 27 to move along the preset path through the telescopic end. The fourth push rod 25 is fixed to the support 24 through the fixed end and connected to the pedal 27 through the movable end, so that the fourth push rod 25 is in an axial horizontal posture, ensuring that the telescopic direction of the movable end is consistent with the telescopic direction of the drawer 28. In use, the movable end of the fourth push rod 25 telescopes along its axis and stops running when the trigger member touches the corresponding limit switch, ensuring that the pedal 27 can be translated and accurately positioned at the use position or the hidden position under the drive of the fourth push rod 25, ensuring the telescopic reliability of the pedal 27 and facilitating use.

[0082] In the embodiment, the through hole 23 is arranged on the rear side wall of the assembly cavity, and the axis of the through hole 23 is consistent with the preset path of the pedal 27. The outer port profile of the through hole 23 matches the profile of the outer end surface of the pedal 27, and the through hole 23 can provide a channel 6 for the pedal 27 to be exposed and hidden, and can be completely blocked by the pedal 27. Specifically, when the pedal 27 is in the use position, the inner end of the pedal 27 hidden in the through hole 23 and the outer end exposed to the outer port of the through hole 23, the top surface of the pedal 27 forms a stepping area exposed to the side wall of the base 1, facilitating the user to get on and off the bed in two steps through the stepping area, and improving the safety of getting on and off the bed by reducing the height of single step. When the pedal 27 is in the hidden position, the pedal 27 is completely hidden in the through hole 23, and the outer end surface of the pedal 27 is in smooth connection with the outer port of the through hole 23, so that the side wall of the base 1 remains flat, hiding the pedal 27 and effectively improving the appearance of the side wall of the base 1.

[0083] In this embodiment, the inner wall of the through hole 23 is provided with a guide plate with a third guide rail 26, and the pedal 27 is provided with a third slider (e.g., ...) that cooperates with the third guide rail 26. Figure 12 As shown, the third guide rail 26 guides the pedal 27 to move along a preset path. The guide plate is set on the top wall of the through hole 23, the third guide rail 26 is set on the bottom surface of the guide plate, and the third slider is set on the top surface of the inner end of the pedal 27. After installation, the third slider can slide along the third guide rail 26, which not only ensures that the pedal 27 can slide accurately along the preset path, but also ensures that the pedal 27 can bear the user's body weight by vertically positioning the inner end of the pedal 27 when the pedal 27 slides to the use position, thus ensuring that the user will not slip and fall due to the pedal 27 tilting under force, effectively ensuring safety during use.

[0084] In this embodiment, there are two guide plates, which are placed on both sides of the top wall of the inner port of the through hole 23 to ensure that the pedal 27 can move horizontally in a preset posture and prevent the pedal 27 from being deflected or offset by force.

[0085] In this embodiment, a limit switch is provided at the inner port of the through hole 23 facing the assembly cavity. The fourth push rod 25 drives the pedal 27 to move along the axis of the through hole 23 and stops running after triggering the limit switch. The limit switch can precisely control the fourth push rod 25 when the pedal 27 moves to the working position or the hidden position, thereby improving the displacement accuracy of the pedal 27.

[0086] In this embodiment, a limit box for mounting a limit switch is provided at the inner port of the through hole 23. The bottom surface of the pedal 27 forms a trigger element by a downward bulge. The pedal 27 moves horizontally and engages with the limit switch through the trigger element, so that the start and stop of the fourth push rod 25 can be controlled. The trigger element can move synchronously with the pedal 27 within the limit box and triggers the corresponding limit switch after the pedal 27 moves into position. By controlling the fourth push rod 25 to stop running, the pedal 27 is ensured to be positioned in a preset position, ensuring the precise movement of the pedal 27. Specifically, the limit box has space for the trigger element to move synchronously with the pedal 27 between the use position and the hidden position, and also has limit switches that control the positioning of the pedal 27 in the use position and the hidden position respectively, thereby ensuring reliability in use.

[0087] In this embodiment, a light strip is embedded in the pedal 27, and a light-transmitting part is provided on the outer end of the pedal 27 away from the fourth push rod 25. The light generated by the light strip is scattered outward through the light-transmitting part. The light strip can be controlled to open and close by a sensor, or it can be manually controlled by the user. When in use, the light generated by the light strip can diffuse outward after passing through the light-transmitting part, ensuring that the light strip can provide illumination and indicate the position of the pedal 27 when the user needs to get on or off the bed.

[0088] In the embodiment, the two side edge sections of the annular surrounding edge 3 are provided with retractable exposed steps 27, and the steps 27 are arranged on the two sides of the base 1 to facilitate the user to get on and off the bed from either side, thereby effectively improving the use convenience. The fourth push rod 25 can perform the retracting action after receiving the instruction from the user, and the instruction can come from the button, the sensor or the mobile terminal, which should all be regarded as the specific embodiments of the application.
