Description

TECHNICAL FIELD

[0001] The present application relates to the field of functional components, in particular to a dual-posture electric storage bed frame. BACKGROUND

[0002] With the development of the home industry, people have more and more functional requirements for beds, and the main function is that the bed frame can be opened to store items in the bed bottom.

[0003] To facilitate the storage of items in the bed bottom, an electric storage bed frame is generally used. After pressing the switch to open the button, the motor is driven to lift the tail of the mattress upwards. When a certain angle is reached, it will be locked in the raised state. At this time, items can be placed. Pressing the switch again will close the button, and the bed plate will reset.

[0004] The existing electric storage bed frame generally only has one horizontal lifting posture. When placing items, the operable space is fixed, and it is not easy to place larger items. If the operable space can be changed, the bed frame will be in an unstable state and needs to be manually locked, which is very inconvenient to use and the user experience is not good. SUMMARY

[0005] In order to change the operation space and place items of different sizes, the present application provides a dual-posture electric storage bed frame.

[0006] The dual-posture electric storage bed frame provided by the present application adopts the following technical solution:

[0007] A dual-posture electric storage bed frame, comprising a mattress support, a bottom carrier, and a drive assembly for driving the mattress support to open or close, the drive assembly comprising a movable rod, a rotating rod, an extension rod, and a drive member for driving the rotating rod to rotate, the movable rod and the mattress support and the bottom carrier form a rotating pair respectively, the rotating rod and the mattress support form a rotating pair, the extension rod and the movable rod and the rotating rod form a rotating pair respectively, and the movable rod itself is foldable and the folding direction is away from the extension rod; when the extension rod is elongated to the maximum length, the drive member can force the movable rod to fold. The movable rod is matched with an elastic member for forcing the movable rod to maintain an extended state.

[0008] By adopting the technical scheme, the movable rod can be folded, and the movable rod can be folded or unfolded by arranging the elastic member and the telescopic rod, so that two posture changes of the mattress support are realized; under the action of the driving member, when the telescopic rod is not elongated to the maximum position, the movable rod will not be pulled, and the elastic potential energy of the elastic member itself can force the movable rod to maintain the unfolded state, so that the two ends of the mattress support are opened in a flush manner. In this way, the articles can be stored at the bottom of the bed, and the pillows or quilts on the mattress support will not fall down, and it is not necessary to take the articles away from the mattress support before opening for storage, which is convenient for placing small articles at the bottom of the bed, and simple and fast. When the telescopic rod is elongated to the maximum length, the driving member continues to work, the telescopic rod pulls the movable rod, and the movable rod starts to fold, so that the distance between the two ends of the movable rod is relatively shortened, and at the same time, since the lengths of the two ends of the rotating rod remain unchanged, the mattress support changes in a manner that one end is high and the other end is low. At this time, it is convenient to place large articles at the bottom of the bed, and one end of the mattress support is higher, so that people can also crawl into the bottom of the bed, and the articles can be placed in a deeper position at the bottom of the bed.

[0009] Optionally, the movable rod comprises a movable upper rod and a movable lower rod; the mattress support and the movable upper rod constitute a rotating pair; the movable lower rod and the bottom carrier constitute a rotating pair; the movable upper rod and the movable lower rod constitute a rotating pair; and the telescopic rod and the movable lower rod constitute a rotating pair.

[0010] By adopting the technical scheme, the movable upper rod and the movable lower rod constitute a rotating pair, so that the folding of the movable rod can be realized; the movable upper rod and the mattress support, and the movable lower rod and the bottom carrier all constitute rotating pairs, so that when the movable rod is folded, the mattress support and the bottom carrier will not generate a large torque on the movable rod, and the rotation is facilitated.

[0011] Optionally, the movable lower rod is fixed with an upper limit stop plate; when the movable upper rod abuts against the upper limit stop plate, the movable upper rod is located at the starting point of the movable rod changing from the unfolded state to the folded state, and at this time, the included angle of the folding direction of the movable rod is greater than 180°.

[0012] By adopting the technical scheme, under the action of the elastic member, the movable upper rod abuts against the upper limit stop plate, at this time, the angle of the folding direction is greater than 180°, so that the movable rod has a self-locking effect, at this time, the two ends of the mattress are flush and in a stable state; when the movable rod is subjected to the pressure of the mattress support, the movable rod will not fold, but will transmit the force to the upper limit stop plate, and since the upper limit stop plate is fixed to the movable lower rod, the force received by the mattress will finally be transmitted to the bottom carrier through the movable lower rod. The self-locking state of the movable rod can make the movable rod bear the pressure, so that the mattress support will not overturn when subjected to external force, the stability of the mattress support is improved, and finally the shaking of the mattress when placing articles at the bottom of the bed is not worried about.

[0013] Optionally, the movable lower rod is fixed with a lower limit stop plate, when the movable upper rod abuts against the lower limit stop plate, the movable upper rod is at the terminal point of the movable rod from the unfolded state to the folded state.

[0014] By adopting the above technical scheme, after the telescopic rod is stretched to the maximum length, the telescopic rod can pull the movable lower rod under the action of the driving member, so that the movable rod starts to change from the unfolded state to the folded state, when the movable upper rod abuts against the lower limit stop plate, the movable rod will not continue to fold, at this time, the movable rod is in a stable state, at this time, the mattress support is high at one end and low at the other end and is in a stable state, when the mattress support is subjected to an external force, the external force will be transmitted to the lower limit stop plate through the movable lower rod, since the upper limit stop plate is fixed to the movable lower rod, the force received by the mattress will ultimately be transmitted to the bottom carrier through the movable lower rod, so that the mattress support will not swing when subjected to an external force, the stability of the mattress support is improved, and finally the mattress will not shake when placing objects on the bed.

[0015] Optionally, the elastic member is a torsion spring, and the torsion spring is arranged at the rotation center of the movable upper rod and the movable lower rod.

[0016] By adopting the above technical scheme, the torsion spring has elastic potential energy, and the movable rod will expand when not subjected to the pulling force of the telescopic rod, and has a tendency to force the movable upper rod to rotate towards the upper limit stop plate.

[0017] Optionally, the rotation center of the rotating rod and the mattress support is defined as a first rotation point, the rotation center of the movable rod and the mattress support is defined as a second rotation point, and the second rotation point and the center of gravity of the mattress support are respectively located on two sides of the first rotation point.

[0018] By adopting the above technical scheme, the center of gravity of the mattress support has a tendency to make the mattress support rotate around the first rotation point, which can reduce the burden of the elastic member, so that the elastic member can reset the mattress support from the state of the two ends being different in height to the state of the two ends being the same in height without too much elastic potential energy.

[0019] Optionally, the elastic member is a gas spring, and the two ends of the gas spring constitute a rotating pair with the movable upper rod and the movable lower rod respectively.

[0020] By adopting the above technical scheme, the gas spring also has elastic potential energy, and has the advantages of simple structure, light weight and convenient installation and maintenance. When not subjected to the pulling force of the telescopic rod, the movable rod will maintain the unfolded state, and under the reset of the gas spring, there will be a certain damping to buffer, so that the two states of the two ends of the mattress support being the same in height and the two ends being different in height are switched smoothly.

[0021] Optionally, the telescopic rod comprises a fixed clamping piece, a sliding rod capable of sliding relative to the fixed clamping piece, and an anti-disengagement part for preventing the fixed seat from disengaging from the fixed clamping piece, the fixed clamping piece and the movable lower rod constitute a rotary pair, and the sliding rod and the rotating rod constitute a rotary pair.

[0022] By adopting the above technical scheme, the sliding rod slides relative to the fixed clamping piece, so that the telescopic rod does not transmit the received tensile force to the movable rod, and the movable rod can be in an unfolded state. The anti-disengagement part can prevent the sliding rod from disengaging from the fixed clamping piece, so that when the telescopic rod is elongated to the maximum distance, it serves as a tensile rod. Under the action of the driving member, the movable rod is folded.

[0023] Optionally, the bottom carrier comprises two bed side plates, and the driving assembly is provided in at least two, and the two driving assemblies are respectively arranged on the two bed side plates.

[0024] By adopting the above technical scheme, the two groups of driving members can improve the stability of the mattress support when it is opened or closed, reduce shaking, and enable the user to place objects in the deep part of the bed bottom with confidence.

[0025] Optionally, at least one synchronization rod is connected between adjacent driving assemblies.

[0026] By adopting the above technical scheme, the synchronization rod is used to connect the driving assemblies, improve the synchronization of the working driving assemblies, and reduce the occurrence of lateral tilting of the mattress support.

[0027] In summary, the present application has at least one of the following beneficial technical effects:

[0028] 1. The two ends of the mattress support are opened in a flush manner. Objects can be stored in the bed bottom, and the pillows or quilts on the mattress support will not fall down, and it is not necessary to remove these objects from the mattress support before opening for storage. It is convenient and simple to place small objects in the bed bottom. The mattress support also has a waterproof opening with one end being low and the other end being high. At this time, it is convenient to place large objects in the bed bottom, and the higher end of the mattress support enables a person to also crawl into the bed bottom and place objects in a deeper position in the bed bottom.

[0029] 2. The movable rod has a self-locking effect, so that the mattress support does not swing when subjected to external force, and the stability of the mattress support is improved. Ultimately, the mattress does not need to be worried about shaking when objects are placed in the bed bottom.

[0030] 3. The center of gravity of the mattress support has a tendency to rotate the mattress support around the first rotation point, which can reduce the burden of the elastic member, so that the elastic member does not need too much elastic potential energy to reset the mattress support from the two-end tilted state to the two-end flush state.

DETAILED DESCRIPTION

[0040] The following will be described in detail with reference to the accompanying drawings. Figures 1-8 The present application will be described in further detail.

[0041] The direction description in the embodiments is all taken as the reference. Figure 1

[0042] Embodiment 1:

[0043] Reference Figure 1 and Figure 2 ​The utility model provides a double posture electric storage bed frame, which comprises a mattress support 10, a bottom carrier 11 and a driving assembly 20 for driving the opening and closing of the mattress support 10 relative to a bed body. The bottom carrier 11 can be the bed body or a part of the bed body, or a support mounted inside the bed body for supporting the driving assembly. The bed body comprises a headboard 111, two sideboards 112 and a footboard 114, the two ends of the headboard 111 are connected with the sideboards 112 respectively, and the sideboards 112 and the footboard 114 are used for supporting the mattress support 10.

[0044] In the embodiment, the sideboard 112 is taken as the bottom carrier 11. The driving assembly 20 is mounted on the inner side of the two sideboards 112 respectively. The driving assembly 20 can make the mattress support 10 have two postures. The first posture is a shallow placing posture: the two ends of the mattress support 10 are flush, at this time, the mattress support 10 close to the footboard 114 is opened to place articles, and the sideboard 112 direction can also place articles, but since the space of the mattress support 10 rising is small, the user is inconvenient to drill into the bed bottom, so it is the shallow placing posture. The second posture is a deep placing posture: the two ends of the mattress support 10 have a difference, the end close to the headboard 111 is lowered, and the end close to the footboard 114 is raised, so that the mattress support 10 close to the footboard 114 is opened to an opening sufficient for the user to enter, and articles can be placed deeply into the bed body, so it is the deep placing posture.

[0045] With reference to Figure 3 The driving assembly 20 comprises a movable rod 21, a rotating rod 22, a driving part 23 and an extension rod 24. In order to make the mattress support 10 tilt away from the headboard 111, the movable rod 21 is arranged closer to the headboard 111 than the rotating rod 22. The two ends of the rotating rod 22 are hingedly connected with the mattress support 10 and the sideboard 112 respectively. The body of the driving part 23 is hingedly connected with the sideboard 112. In the embodiment, the driving part 23 is an electric push rod. The output shaft of the driving part 23 is hingedly connected with the rotating rod 22, so that the rotating rod 22 serves as a driving part, and the movable rod 21 serves as a driven part.

[0046] The movable rod 21 comprises a movable upper rod 211, a movable lower rod 212 and an elastic part. The movable upper rod 211 and the movable lower rod 212 are hingedly connected with each other, so that the movable rod 21 can be folded or unfolded. In the embodiment, the elastic part is a torsion spring 213, which is arranged at the rotation center of the movable upper rod 211 and the movable lower rod 212. The elastic potential energy of the torsion spring 213 makes the movable rod 21 have a tendency to be unfolded. In the embodiment, the two ends of the extension rod 24 are hingedly connected with the movable lower rod 212 and the rotating rod 22 respectively. In other embodiments, the movable rod 21 can also take the form of a multi-link mechanism to increase the posture change of the mattress support.

[0047] With reference to Figure 4 and Figure 5The upper limit stop plate 214 and the lower limit stop plate 215 are arranged in the movable lower rod 212. When the movable upper rod 211 abuts against the upper limit stop plate 214, the included angle between the movable upper rod 211 and the movable lower rod 212 and away from the telescopic rod 24 is 185°. At this time, the included angle is unfolded to the maximum angle. In this way, the movable rod 21 can realize a self-locking state, avoiding the problem that the movable rod 21 is folded after the mattress support 10 is pressed. At this time, the mattress support 10 is in a shallow laying posture. It should be noted that the angle is not the only maximum angle defined in the present application. In actual parameter setting, any angle in 180°-200° can be selected as the maximum angle. When the movable upper rod 211 abuts against the lower limit stop plate 215, the included angle between the movable upper rod 211 and the movable lower rod 212 and away from the telescopic rod 24 is 30°. At this time, the included angle is folded to the minimum angle. At this time, the mattress support 10 is in a deep laying posture. It should be noted that the angle is not the only minimum angle defined in the present application. In actual parameter setting, any angle in 15°-60° can be selected as the minimum angle. The upper limit stop plate 214 and the lower limit stop plate 215 are both covered with felt, which can play a buffering role.

[0048] With reference to Figure 6 and Figure 7 The telescopic rod 24 includes a fixed clamping piece 241, a sliding rod 242 and an anti-disengagement part 244. The fixed clamping piece 241 is in a U shape, the opening end of the U-shaped fixed clamping piece 241 is hinged to the rotating rod 22, the two side walls of the fixed clamping piece 241 are fixed with a fixed seat 243, the sliding rod 242 can pass through the fixed seat 243 and slide relative to the fixed clamping piece 241, and the anti-disengagement part 244 can prevent the sliding rod 242 from sliding out of the fixed seat 243. The anti-disengagement part 244 includes a nut 2441 and a gasket 2442, the end of the sliding rod 242 is provided with a threaded segment 2443, the gasket 2442 is first sleeved into the threaded segment 2443 so that the gasket 2442 abuts against the shaft side surface of the sliding rod 242, and then the nut 2441 is screwed on the threaded segment 2443. The gasket 2442 plays a role of anti-loosening. The end of the sliding rod 242 away from the anti-disengagement part 244 is hinged to the rotating rod 22. In other embodiments, the telescopic rod 24 can also be replaced by a flexible piece, such as a pull rope or an iron wire.

[0049] The rotation center of the rotating rod 22 and the mattress support 10 is defined as the first rotation point 30, and the rotation center of the movable rod 21 and the mattress support 10 is defined as the second rotation point 40. The part of the mattress support 10 close to the first rotation point 30 is the collapsed section 31, and the part of the mattress support 10 away from the first rotation point 30 is the raised section 32. The length of the raised section 32 is greater than that of the collapsed section 31, so that the center of gravity of the mattress support 10 is located in the raised section 32. Because the collapsed section 31 is smaller than the raised section 32, under the gravity of the raised section 32, the torsional spring 213 does not need too much force to make the movable upper rod 211 push up the collapsed section 31, so that the movable rod 21 always remains in an unfolded state. The collapsed section 31 is prevented from being too heavy to be reset by the torsional spring 213. When the movable rod 21 is fully unfolded, the mattress support 10 is in a shallow placement posture, and when the movable rod 21 is fully folded, the mattress support 10 is in a deep placement posture.

[0050] In this embodiment, the synchronization rod 113 is one, and the two ends of the synchronization rod are connected with the movable lower rod 212. In other embodiments, multiple synchronization rods can be provided and connected between the two movable rods 21 and / or between the two rotating rods 22. To improve stability and synchronization, the drive assemblies 20 on the two bottom carriers 11 are connected by a synchronization rod 113.

[0051] In this embodiment, the main connection between the components is hinged, and in other embodiments, the hinge can be replaced by a rotating rivet.

[0052] The initial state of the mattress support 10 is that the mattress support 10 is supported by the bottom carrier 11, and under the action of the elastic member, the movable upper rod 211 is at the maximum rotation angle position, and the telescopic rod 24 is at the minimum contraction length.

[0053] When it is necessary to make the mattress support 10 in a shallow placement posture: the drive member 23 starts to work, and pushes the rotating rod 22 to rotate clockwise, and the movable rod 21 and the rotating rod 22 jointly support the mattress support 10 to lift; although the telescopic rod 24 is directly connected with the movable rod 21 and the rotating rod 22, since the slide rod 242 of the telescopic rod 24 has not been extended to the limit, the telescopic rod 24 will only be extended under the pulling of the rotating rod 22 at this time, so the telescopic rod 24 will not pull the movable rod 21 to fold. The movable rod 21 and the rotating rod 22 can make the two ends of the mattress support 10 flush during opening. After the drive member 23 stops working, the mattress support 10 is in a shallow placement posture, and the mattress support 10 can be kept stable.

[0054] To indicate the rotation direction of the rotating rod 22 and the movable rod 21, in this embodiment, the movable rod is on the left side and the rotating rod is on the right side, and at this time, the clockwise direction of the rotating rod rotating to the right side.

[0055] The reason why the mattress support 10 is stable in the shallow position is that the center of the mattress support 10 of the present application is located at the raised section 32, which will be turned clockwise around the first rotating point 30 under the action of gravity, at which time the movable rod 21 will pull the collapsed section 31 to prevent the mattress support 10 from turning clockwise. When the collapsed section 31 is pressed, the mattress support 10 has a tendency to turn counterclockwise around the first rotating point 30, but when the movable rod 21 is unfolded by 185°, the pressure is resisted by the upper limit stop plate 214, so that the movable rod 21 can resist the collapsed section 31 to turn downward, thereby preventing the mattress support 10 from turning counterclockwise. The four-bar mechanism is formed by the bed side plate 112, the mattress support 10, the movable rod 21 and the rotating rod 22, at which time the driving member 23 does not work, which will limit the rotating rod 22 to prevent the four-bar mechanism from rotating, thereby forming a stable state.

[0056] When it is needed to make the mattress support 10 in the deep position, on the basis of the mattress support 10 in the shallow position, the driving member 23 continues to work to push the rotating rod 22 to rotate clockwise, and when the telescopic rod 24 is elongated to the limit position, the telescopic rod 24 can transmit the pulling force of the rotating rod 22. The rotating rod 22 continues to rotate clockwise, and the telescopic rod 24 will pull the movable rod 21, since the telescopic rod 24 is connected to the movable lower rod 212, when the pulling force of the telescopic rod 24 is greater than the torsional force of the torsional spring 213 and the torque exerted by the center of gravity of the mattress support 10, the telescopic rod 24 will pull the movable lower rod 212 to rotate clockwise relative to the bed side plate 112, and will make the movable upper rod 211 rotate counterclockwise relative to the movable lower rod 212, so that the movable rod 21 enters the folded state. When folded to the final state, the movable upper rod 211 abuts against the lower limit stop plate 215, and the movable rod 21 is at the minimum angle of 30° in the folded state, at which time the driving member 23 stops working, and the posture of the bed frame is the deep position.

[0057] The reason why the mattress support 10 is stable in the deep position is that the lower limit stop plate 215 prevents the collapsed section 31 from continuing to move downward, and since the driving member 23 does not work, the rotating rod 22 is also fixed, so that the telescopic rod 24 always maintains a pulling state to the movable lower rod 212 to limit the movable lower rod 212 from rotating counterclockwise, which can prevent the lower end from moving upward, thereby forming a stable state.

[0058] When resetting, the driving member 23 makes the rotating rod 22 rotate counterclockwise, and the position limitation of the telescopic rod 24 to the movable rod 21 is gradually released, and the folded movable rod 21 gradually unfolds under the action of the torsional spring 213, when the movable rod 21 is unfolded to the maximum angle, the mattress support 10 is reset from the deep position to the shallow position. Then, the driving member 23 can continue to drive the rotating rod 22 to rotate counterclockwise, and the telescopic rod 24 starts to contract, and at the same time, the movable rod 21 also starts to rotate counterclockwise, until the mattress support 10 is in the initial position.

[0059] In this embodiment, the center of gravity of the mattress support 10 is located at the raised section 32, so the torsion spring 213 of the movable rod 21 does not need too much force to make the movable upper rod 211 push the collapsed section 31 to move upward. That is, the torque of the raised section 32 and the torque of the torsion spring 213 can assist the mattress support 10 to recover from the two-end difference to the two-end flush posture.

[0060] Embodiment: 2

[0061] With reference to Figure 7 and Figure 8 , the difference between this embodiment and the embodiment is that the elastic member is a gas spring 25, and the two ends of the gas spring 25 are respectively hinged to the movable upper rod 211 and the movable lower rod 212. The folding of the movable rod 21 is achieved by the extension and contraction of the gas spring 25, because the gas spring 25 has a certain damping to buffer, so that the two states of the two-end flush and the one-end high and the other-end low of the two mattress supports 10 are switched smoothly.

[0062] Embodiment 3: The difference between this embodiment 3 and the embodiment 1 is that the elastic member includes a gas spring 25 and a torsion spring 213, and the movable upper rod 211 and the movable lower rod 212 are connected by the torsion spring 213, and the gas spring 25 is also added, and the two ends of the gas spring 25 are respectively hinged to the movable upper rod 211 and the movable lower rod 212. Because the gas spring 25 has a certain damping to buffer, so that the two states of the two-end flush and the one-end high and the other-end low of the two mattress supports 10 are switched smoothly.

[0063] The above are the preferred embodiments of the present application, which do not limit the protection scope of the present application, so: any equivalent changes made on the basis of the structure, shape, principle of the present application should be covered within the protection scope of the present application.
