Abstract
Description
Technical Field
[0001] The invention relates to a massage bed, in particular to an electric storage bed. Background Art
[0002] In modern home design, as urban living space becomes increasingly compact, how to efficiently utilize limited space has become the focus of attention. Traditional bed designs often only meet basic sleeping needs, while ignoring the huge potential of the space under the bed. In order to place items and improve space utilization, although there are already some beds with storage functions on the market, such as drawer beds or air-supported beds, most of these products have the following shortcomings: manual operation is cumbersome, and most traditional storage beds require users to manually open or close the storage space, which is not only inconvenient to operate, but also requires the user to lift the mattress part before taking items from the existing storage beds, which is particularly laborious when storing large or heavy items, and it is easy to mess up or drop the existing items on the bed; due to the limited height of the mattress, the space for taking items is also quite limited, and it is very inconvenient to take items, especially large items. This design is obviously not friendly enough for the elderly, the physically disabled, or modern people who pursue convenience in life. Summary of the invention
[0003] Therefore, in order to solve the above-mentioned problems, the present invention provides an electric storage bed that can automatically perform moving and lifting operations.
[0004] An electric storage bed comprises a bed frame, a storage rack, a guide rail assembly, and a driving device. The bed frame is provided with a first bed surface. The guide rail assembly is arranged between the bed frame and the storage rack, and drives the storage rack to move. Under the guidance of the guide rail assembly, the driving device drives the storage rack to move out or retract under the bed frame; the storage rack is provided with a lifting device and a second bed surface. When the storage rack moves out from under the bed frame, the lifting device pushes the second bed surface to rise or fall; the guide rail assembly comprises guide rails arranged on two opposite sides of the bed frame, and guide rail pulleys correspondingly arranged on two opposite sides of the storage rack. When the driving device drives the storage rack to move, the guide rail assembly is used to guide the moving direction of the storage rack.
[0005] The technical solution provided by the present invention has the following beneficial effects: by electrically driving the storage rack and the lifting device, the guide rail assembly is arranged on the opposite side of the bed frame, so that the storage rack can be accurately guided to move out or retract under the bed frame. Then, the lifting device can smoothly rise or fall after the storage rack is moved into place, so that the electric storage bed has the advantage of automatic movement and lifting of the storage rack.

These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, a person of ordinary skill in the art should be able to understand other possible implementations and advantages of the present invention.

[0009] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.
[0010] Reference Figures 1 to 7As shown, an electric storage bed provided in this embodiment includes a bed frame 1, a storage rack 2, a guide rail assembly 3, and a driving device 4. The bed frame 1 is provided with a first bed surface 91, and the guide rail assembly 3 is arranged between the bed frame 1 and the storage rack 2 to drive the storage rack 2 to move. Under the guiding action of the guide rail assembly 3, the driving device 4 drives the storage rack 2 to move out or retract under the first bed surface 91 of the bed frame 1; the storage rack 2 is provided with a lifting device 6 and a second bed surface 62, when the storage rack 2 moves out from under the bed frame 1, the lifting device 6 pushes the second bed surface 62 to rise or fall; the guide rail assembly 3 includes a guide rail 31 arranged on the inner side of the bed frame 1 and opposite to each other, and a guide rail pulley 32 arranged on the outer side of the storage rack 2 and opposite to the guide rail. When the driving device 4 drives the storage rack 2 to move, the guide rail assembly 3 is used to guide the moving direction of the storage rack 2. The storage rack 2 is driven out by the driving device 4 to facilitate the storage and retrieval of stored items; and a mattress can be set on the second bed surface 62, and the second bed surface 62 can be raised to the same height as the first bed surface 91 by the lifting device 6 to expand the actual use area of the bed.
[0011] Further, the driving device 4 is arranged in the middle of the storage rack 2, and at least two bottom rollers 22 are arranged at the bottom of the storage rack 2 and away from the driving device 4. The bottom rollers 22 are arranged at the bottom of the storage rack 2 to further support the movement of the storage rack 2. Furthermore, the bottom rollers 22 and the driving device 4 are arranged on the side of the storage rack 2 to reduce the internal space of the storage rack 2.
[0012] Furthermore, a massage device is included, which is arranged on the second bed surface 62, and the storage rack can be removed at any time according to needs to obtain a massage experience. Specifically, the structure and working principle of the massage device are both existing technologies and will not be described in detail here.
[0013] Furthermore, the driving device 4 includes a motor 41, a worm 42, a turbine 43 and a driving wheel 44, wherein the motor 41 is connected to the worm 42, the worm 42 drives the turbine 43 to rotate, and the turbine 43 is connected to the driving wheel 44. After the motor 41 stops, due to the self-locking effect of the worm 42 and the turbine 43, when the driving wheel 44 stops rotating, the storage rack 2 is fixed in the current position. The condition for the worm 42 and the worm wheel 43 to form a self-locking structure is: when the indexing cylindrical lead angle (that is, the helix angle) of the worm 42 is less than or equal to the equivalent friction angle (γ≤ρ), self-locking can be achieved, that is, the worm wheel 43 can only be actively driven by the worm 42, and the worm wheel 43 cannot drive the worm 42. After the motor 41 stops, the turbine 43 is stuck by the worm 42 and cannot rotate, so that the drive wheel 44 connected to the turbine 43 cannot rotate. This mechanical structure can safely and reliably fix the position of the storage rack 2 when the motor 41 stops. By driving the storage rack 2 with the motor 41, users can easily store and retrieve items, and the self-locking mechanism of the worm gear 43 and the worm 42 also ensures that the storage rack 2 can stay stably at any position, improving the safety and reliability of use. Of course, in other embodiments, a gear set can be set between the turbine 43 and the drive wheel 44 to obtain the transmission ratio required to move the storage rack 2.
[0014] Furthermore, the driving device 4 includes a motor 41 and two driving wheels 44, the driving wheels 44 are arranged in parallel with each other and rotate synchronously, and the motor 41 drives the two driving wheels 44 to rotate synchronously to maintain linear motion. Furthermore, the driving wheels 44 are arranged on both sides of the motor 41 to eliminate the torque generated when the single-side driving wheel is working, and reduce the pressure on the guide pulley 32 in the non-guided direction.
[0015] Furthermore, the rotation axis direction of the guide pulley 32 is the vertical direction, and the guide pulley 32 moves in the guide rail 31; the width of the guide rail 31 in the vertical direction is wider than the width of the guide pulley 32, and there is a gap between the guide pulley 32 and the upper side wall and / or the lower side wall of the guide rail 31, so that when the storage rack 2 is moved, the guide pulley 32 not only plays a guiding role but also can be offset up and down a certain distance in the guide rail 31. The guide pulley 32 is arranged horizontally, that is, the rotation axis direction of the guide pulley 32 is the vertical direction, and the guide pulley 32 guides the storage rack 2 to move back and forth. The guide rail 31 can adopt an upper and lower guide rail limit plate protruding from the inner side of the bed frame 1; or only an upper limit plate is set, and the guide pulley 32 is set between the upper limit plate and the ground and is subject to upper and lower limit effects. Since the driving wheel 44 always needs to contact the ground to provide driving force, and the guide pulley 32 can be offset up and down, the storage rack 2 can be stably removed or retracted even if the ground flatness is different. Other guide rail assemblies, such as the drawer guide rails in the furniture field, generally use guide wheels with a rotating axis in the horizontal direction. The guide wheels are fixed by the upper and lower limits of the guide rails in the vertical direction. The guide rail assembly can only move in the horizontal direction. If the ground is uneven, the driving wheel will be separated from the ground and suspended due to the limit of the guide rail, thereby losing the driving force. In this application, the storage rack 2 often needs to bear the weight of storage items such as mattresses and clothes. The guide rail assembly 3 has a high requirement for the stability of the guiding effect of the removal or retraction of the storage rack 2. Due to the uneven load distribution of the storage rack 2 and the different friction between the driving wheel 44 and the ground, the driving unit 4 is given different torques, thereby affecting the linear movement of the storage rack 2. Therefore, the guide rail assembly 3 often needs to bear the pressure brought by the storage rack 2 in other directions other than the guiding direction. The rotating axis of the present application is in the vertical direction, and the guide rail pulley 32 moves along the guide groove 31 and can be offset up and down, which can guide the storage rack 2 to move along a predetermined path to ensure the accuracy and stability of the movement.
[0016] Furthermore, the storage rack 2 is provided with two guide rail pulley mounting columns 21, and the guide rail pulleys 32 are respectively arranged on the guide rail pulley mounting columns 21, and the guide rail pulley mounting columns 21 extend out of the storage rack 2, so that when the storage rack 2 is moved out from under the bed frame 1, the guide rail pulleys 32 contact the guide rails. In order to reduce the space occupied in the length direction of the storage rack 2, the length of the storage rack 2 can be as consistent as possible with the length of the bed frame 1, and the user can place a mattress on the storage rack 2, and the user can use the storage rack 2 and the mattress as another bed.
[0017] Furthermore, the lifting device 6 includes an electric push rod 61 connected to the second bed surface 62, and the other end of the electric push rod 61 is connected to the storage rack 2, and the electric push rod 61 supports and pushes the second bed surface 62 to rise and fall. After the storage rack 2 is moved out, the storage rack 2 will not move when the second bed surface 62 is raised or lowered due to the self-locking effect of the worm 42 and the turbine 43, so that the lifting process of the second bed surface 62 is more stable. The user can place a mattress on the second bed surface 62, so that when the storage rack 2 is moved outward and the mattress of the second bed surface 62 rises to the same height as the mattress of the bed frame 1, the user can get a bed with extended width. Preferably, the electric push rod 61 is arranged on the side of the storage rack 2 to maximize the storage space of the storage rack 2.
[0018] Furthermore, the lifting device 6 also includes a scissor part 7, which includes two scissor columns 71 that are cross-arranged and hinged in the middle, and the scissor part 7 also includes sliders 72 and slider grooves 73 for the sliders to slide, which are respectively arranged on the second bed surface 62 and the storage rack 2. One ends of the two scissor columns 71 are fixedly hinged to the second bed surface 62 and the storage rack 2, respectively, and the other ends of the two scissor columns 71 are fixedly hinged to the sliders 72 in the slider grooves 73, respectively. The scissor part 7 is opened and closed by the hinge of the scissor columns 71 and the sliding of the slider 72, so that the second bed surface 62 is lifted and lowered along the vertical direction. The structural design of the scissors portion 7 between the second bed surface 62 and the storage rack 2 is one of the more preferred embodiments of the present scheme. Of course, in other embodiments, the structural design between the second bed surface 62 and the storage rack 2 is not limited thereto, such as providing a vertical guide rail on the storage rack 2 and providing guide wheels on the second bed surface 62, so that the second bed surface 62 can stably move in the vertical direction.
[0019] Furthermore, it also includes a controller 5, magnets 81 are provided at both ends of the guide rail 31, and a Hall sensor 82 is provided on the storage rack 2. When the storage rack 2 is completely moved out or completely retracted under the bed frame 1, the Hall sensor 82 senses the magnet 81 and sends a signal to the controller 5 to control the drive device 4 to stop working. The controller 5 can also control the operation of the drive device 4 and the electric push rod 61. Of course, the magnet 81 and the Hall sensor 82 are provided to monitor whether the relative position relationship between the storage rack 2 and the bed frame 1 has reached the preset position, so the position of the magnet 81 and the Hall sensor 82 can also be set at other positions of the bed frame 1 and the storage rack 2. In other embodiments, the magnet 81 and the Hall sensor 82 may not be used, and a travel switch, an optical coupler switch or a sensor of similar nature may also be used.
[0020] A baffle 11 is respectively disposed on two opposite side walls of the bed frame 1, and a baffle 23 is disposed on the storage rack 2 corresponding to the baffle 11. When the storage rack 2 is to be retracted under the bed body 1, the two driving wheels 44 first rotate forward to drive the two baffles 23 to abut against the two baffles 11, and then the two driving wheels 44 reverse to drive the storage rack 2 to move to the bottom of the bed body 1. By driving the baffles 23 to abut against the baffles 11, it can be ensured that the direction of the storage rack 2 is facing the direction in which the guide rail 31 extends. In this way, even if the working process may cause the moving direction and angle of the storage rack 2 to change, when the storage rack 2 is to be retracted, its moving direction can be corrected by the abutment between the baffles 23 and the baffles 11, so that it can be smoothly retracted under the bed body 1. The structural design of the block 23 and the baffle 11 is one of the more preferred embodiments in the present scheme, so as to promote and realize the precise angle correction of the storage rack 2. Of course, in other embodiments, the structural design of the block and the baffle is not limited to this. For example, if the block is not used, the guide rail pulley 32 is used to abut against the baffle to realize the angle correction of the storage rack 2.
[0021] All the action mechanisms and control components of the electric storage bed of the present application are arranged in the bed frame, and a modular design is adopted. The product uses a small number of parts, which can save packaging and transportation costs, greatly reduce the difficulty of product assembly, and users can assemble it by themselves, and maintenance is also simple and quick.
[0022] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, it should be understood by those skilled in the art that various changes may be made to the present invention in form and details without departing from the spirit and scope of the present invention as defined by the appended claims, all of which are within the scope of protection of the present invention.
