DETAILED DESCRIPTION

[0038] ​​The technical solutions of the present utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0040] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0041] like Figures 1 to 10 As shown in the figure, this embodiment demonstrates a multifunctional folding furniture, including a cabinet 1 with a receiving cavity 11, a bed frame 2 rotatably connected to the receiving cavity 11, and a table frame 3 rotatably connected to the bed frame 2. The bed frame 2 can be flipped open or stored in the receiving cavity 11, and the table frame 3 can be unfolded relative to the bed frame 2 or stored in the bed frame 2. A first locking member 25 is provided between the cabinet 1 and the bed frame 2, and the bed frame 2 is locked in the receiving cavity 11 by the first locking member 25. A second locking member 35 is provided between the bed frame 2 and the table frame 3, and the second locking member 35 fixes the table frame 3 and stores it in the bed frame 2. The folding furniture also includes a control mechanism electrically connected to the first locking member 25 and the second locking member 35. The control mechanism controls the first locking member 25 to be unlocked only when the second locking member 35 locks the table frame 3, and the control mechanism controls the second locking member 35 to be unlocked only when the first locking member 25 locks the bed frame 2.

[0042] The bed frame 2 is locked by the first locking member 25 after being received in the receiving cavity 11 in the embodiment, so as to limit the bed frame 2 from automatically turning over and separating from the receiving cavity 11, and the table frame 3 is locked by the second locking member 35, so as to enable the table frame 3 to be received in the bed frame 2, and further limit the table frame 3 from being unfolded, and the control mechanism can realize the logical interlocking of the bed frame 2 and the table frame 3. When it is needed to lower the bed frame 2, the table frame 3 needs to be locked by the second locking member 35 first, and then the control mechanism can control the first locking member 25 to be unlocked, that is, the bed frame 2 can be lowered only after the table frame 3 is received and locked. Similarly, when it is needed to unfold the table frame 3, the bed frame 2 needs to be locked by the first locking member 25 first, and then the control mechanism can control the second locking member 35 to be unlocked, that is, the table frame 3 can be unfolded only after the bed frame 2 is received and locked. That is, only after one of the bed frame 2 and the table frame 3 is locked, the other one can be unlocked and unfolded, so as to ensure that the second locking member 35 cannot be mistakenly triggered to cause the table frame 3 to be automatically unfolded when the user uses the bed frame 2, reduce the possibility that the table frame 3 is damaged due to collision, make the receiving and fixing of the table frame 3 more firm and reliable. Similarly, the first locking member 25 cannot be mistakenly triggered to cause the bed frame 2 to be loosened and turned over when the user uses the table frame 3, so as to ensure that the table frame 3 can be kept stable and reliable during use, avoid the table frame 3 from being inclined due to the turning over of the bed frame 2, reduce the possibility that the user is pressed by the bed frame 2, make the table frame 3 have higher use safety, and help to reduce the safety hidden danger of the folding furniture.

[0043] As shown in Figures 2 to 5 , the receiving cavity 11 is provided with a force bearing plate 15 and a driving mechanism 4 in the embodiment. The bed frame 2 is rotationally connected to the cabinet 1 through the force bearing plate 15. The driving mechanism 4 comprises a linear actuator. The linear actuator comprises a power unit provided with an actuating torque by a motor 41 and a tubular telescopic unit 42 driven by the actuating torque. The driving mechanism 4 is hingedly connected to the inner wall of the receiving cavity 11. The output end of the motor 41 is in transmission connection with the tubular telescopic unit 42. The motor 41 controls the tubular telescopic unit 42 to be telescoped. One end of the tubular telescopic unit 42 away from the motor 41 is hingedly connected to one end of the bed frame 2 close to the bottom of the cabinet 1. After the motor 41 is started, the motor 41 controls the tubular telescopic unit 42 to be elongated. Then, the whole bed frame 2 rotates upward around the hinged position of the force bearing plate 15 until the whole bed frame 2 is vertical. At this time, the bed frame 2 is received in the receiving cavity 11. The bottom plate 21 of the bed frame 2 serves as the front plate of the cabinet 1. Refer to Figure 1 . When the motor 41 controls the tubular telescopic unit 42 to be contracted, the whole bed frame 2 rotates downward around the hinged position of the force bearing plate 15, that is, the bed frame 2 gradually moves away from the receiving cavity 11 and is unfolded until the whole bed frame 2 is kept horizontal. At this time, the bed frame 2 reaches the maximum unfolded state. Refer to Figure 4 and Figure 5 .

[0044] As shown in Figure 2As shown, the first locking member 25 is installed at the end of the bed frame 2 away from the bearing plate 15 in the embodiment, and the top wall of the accommodating cavity 11 is provided with a first locking hole 12. When the bed frame 2 is flipped upward to reach the vertical state, the locking tongue of the first locking member 25 extends into the first locking hole 12, and the cooperation of the first locking member 25 and the first locking hole 12 realizes the locking of the bed frame 2 and the cabinet body 1. In addition, in order to avoid the locking tongue of the first locking member 25 from being stuck when it enters the first locking hole 12, the side of the locking tongue of the first locking member 25 away from the bottom plate 21 is provided with a guide surface in the embodiment. During the upward rotation of the bed frame 2, the top plate of the cabinet body 1 acts on the guide surface of the locking tongue, so that the locking tongue is compressed. When the locking tongue is below the first locking hole 12, the locking tongue will automatically pop out and extend into the first locking hole 12 after losing the compression force, thereby realizing the locking of the first locking member 25 and the first locking hole 12.

[0045] As shown in the drawings, Figure 2 In addition, since the locking tongue of the first locking member 25 has a guide surface, the locking cooperation of the first locking member 25 and the first locking hole 12 can only limit the rotation of the bed frame 2 away from the cabinet body 1, but cannot limit the rotation of the bed frame 2 toward the cabinet body 1. Therefore, the inner wall of the accommodating cavity 11 is provided with a limiting plate 13 in the embodiment. When the bed frame 2 reaches the vertical state, the limiting plate 13 forms a limiting cooperation with the bed frame 2, limiting the first locking member 25 from disengaging from the first locking hole 12 toward the direction of the accommodating cavity 11. The rotation angle of the bed frame 2 is limited to 90° by the limiting plate 13, so that the bed frame 2 can be kept straight after being stored, and the appearance of the entire cabinet 1 is more beautiful. In addition, after the bed frame 2 is locked in the accommodating cavity 11, the locking cooperation of the first locking member 25 and the first locking hole 12 limits the rotation of the bed frame 2 away from the cabinet body 1, and the limiting cooperation of the limiting plate 13 and the bed frame 2 limits the rotation of the bed frame 2 toward the cabinet body 1. That is, both rotation directions of the bed frame 2 are limited, thereby limiting the shaking amplitude of the bed frame 2 after being locked, ensuring that the table frame 3 can be kept stable and reliable during use, and helping to improve the user's experience.

[0046] In addition, the folding furniture in the embodiment further comprises a first detection member for detecting the turning state of the bed frame 2 and a second detection member for detecting the unfolding state of the table frame 3. The bed frame 2 and the cabinet body 1 are locked by the first locking member 25 to trigger the first detection member. The table frame 3 and the bed frame 2 are locked by the second locking member 35 to trigger the second detection member. The first detection member is installed on the driving mechanism 4. The first detection member is used to detect the stroke of the tubular telescopic unit 42. The first detection member judges the turning angle of the bed frame 2 according to the length of the tubular telescopic unit 42. When the bed frame 2 is locked in the accommodating cavity 11, the stroke of the tubular telescopic unit 42 is the largest. When the bed frame 2 is unfolded and can be used, the stroke of the tubular telescopic unit 42 is the smallest. The first detection member can limit the stroke range of the tubular telescopic unit 42 according to the two extreme states of the bed frame 2. When the stroke of the tubular telescopic unit 42 reaches the end point of the stroke range, the first detection member can send an electrical signal to the control mechanism to make the control mechanism stop the motor 41, so as to avoid the motor 41 from running after the bed frame 2 reaches the extreme state. The first detection member can make the driving mechanism 4 run more accurately and reliably, reduce the possibility of damage of the driving mechanism 4, and help to prolong the service life of the driving mechanism 4. In addition, the first detection member can detect the stroke of the tubular telescopic unit 42, and then accurately judge the turning angle of the bed frame 2 through the stroke of the tubular telescopic unit 42, so that the detection result of the first detection member has higher accuracy.

[0047] As shown in Figure 3 and Figure 7 In the embodiment, the table frame 3 is hinged to one side of the bed frame 2 close to the bottom plate 21. The second locking member 35 is fixed on the bed frame 2. The table frame 3 is provided with a second lock hole 332 and a third lock hole 322. When the second locking member 35 is locked and matched with the second lock hole 332, the upper surface of the table frame 3 is perpendicular to the bottom plate 21 of the bed frame 2. At this time, the table frame 3 is in an unfolded state and can be used by the user to place articles. When the second locking member 35 is locked and matched with the third lock hole 322, the upper surface of the table frame 3 is parallel to the bottom plate 21 of the bed frame 2 and is in the same plane. At this time, the upper surface of the table frame 3 serves as part of the bottom plate 21 of the bed frame 2. The second locking member 35 is locked and matched with the second lock hole 332 and the third lock hole 322 respectively, so that the table frame 3 is kept in an unfolded state and a storage state respectively. The table frame 3 is not easy to rotate randomly when it is used and stored, which can improve the connection stability of the table frame 3 and the bed frame 2, reduce the shaking amplitude of the table frame 3 when it is used, and help to improve the user experience. In addition, only one second locking member 35 can fix the two states of the table frame 3, which can reduce the number of second locking members 35, reduce the manufacturing cost, and improve the utilization rate of the second locking members 35.

[0048] As shown in Figure 6 and Figure 7As shown, the second detection member in the embodiment includes a sensor arranged on the bed frame 2 and a trigger arranged on the bed frame 2, the sensor is a micro switch 37, the tabletop 31 of the table frame 3 serves as the trigger, the button of the micro switch 37 faces the tabletop 31 of the table frame 3, when the second locking member 35 and the third lock hole 322 are locked and matched, the bottom of the tabletop 31 will press the button of the micro switch 37, so that the micro switch 37 is triggered, and then it is judged that the table frame 3 is locked by the second locking member 35; when the second locking member 35 is separated from the third lock hole 322, an included angle will be formed between the table frame 3 and the bed frame 2, the bottom of the tabletop 31 will be away from the bed frame 2, and then the press on the button of the micro switch 37 is released, so that the micro switch 37 is disconnected, and then it is judged that the table frame 3 has been unlocked, after the table frame 3 is stored in place, the table frame 3 will press the micro switch 37 to trigger the micro switch 37, the triggering mechanism of the micro switch 37 is simpler and more reliable, and it is not easy to be disturbed by other external factors such as electromagnetism, so that the micro switch 37 has higher reliability, which is helpful to realize accurate control on the state of the table frame 3.

[0049] Of course, it can be understood that in other embodiments, the sensor can also be a hall switch installed on the bed frame 2, and the trigger can be a magnet fixed to the table frame 3, the cooperation of the hall switch and the magnet realizes non-contact detection, avoids wear and failure caused by long-term contact and collision, and helps to improve the reliability and service life of the sensor.

[0050] The first locking member 25 and the second locking member 35 in the embodiment are electrically connected with the control mechanism, the user can use a remote controller or a mobile terminal to operate the controller to unlock the first locking member 25 or the second locking member 35, in order to avoid that the bed frame 2 and the table frame 3 are unlocked and expanded at the same time, the control mechanism in the embodiment judges the state of the bed frame 2 and the table frame 3 according to the detection results of the first detection member and the second detection member, so that the bed frame 2 and the table frame 3 can only be unlocked one at a time, that is, when the bed frame 2 is locked by the first locking member 25 and is in the storage state, the control mechanism can control the second locking member 35 to be unlocked, so that the table frame 3 can be normally expanded; when the table frame 3 is locked by the second locking member 35 and is in the storage state, the control mechanism can control the first locking member 25 to be unlocked, so that the bed frame 2 can be normally expanded.

[0051] Specifically, for example, when a user needs to unlock bed frame 2, the control mechanism first determines whether table frame 3 is in a retracted state. If table frame 3 is locked by the second locking element 35, the micro switch 37 is triggered, and the control mechanism can control the first locking element 25 to unlock, allowing bed frame 2 to unfold normally. However, if table frame 3 is not locked by the second locking element 35, the micro switch 37 is off, and the control mechanism locks the first locking element 25, preventing it from unlocking normally. The user must retract table frame 3 before bed frame 2 can be unlocked. Similarly, when a user needs to unlock table frame 3, the control mechanism first determines whether bed frame 2 is in a retracted state. If bed frame 2 is locked by the first locking element 25, the control mechanism... The mechanism can control the second locking element 35 to unlock, allowing the table frame 3 to unfold normally. If the bed frame 2 is not locked, the bed frame 2 must be folded up before the table frame 3 can be unlocked. Through the above-mentioned interlocking logic, the bed frame 2 and the table frame 3 can only be unlocked and unfolded when one of them is locked. This ensures that the second locking element 35 will not be accidentally triggered when the user is using the bed frame 2, thus preventing the table frame 3 from unfolding automatically and reducing the possibility of the table frame 3 being damaged by a collision. It also ensures that the table frame 3 remains stable and reliable during use, preventing the table frame 3 from tilting when the bed frame 2 is flipped, reducing the possibility of the user being crushed by the bed frame 2, making the table frame 3 safer to use, and helping to reduce the safety hazards of folding furniture.

[0052] It is understandable that in other embodiments, the first locking member 25 and the second locking member 35 may also have a first unlocking part and a second unlocking part, respectively. The first unlocking part is exposed on the outer surface of the cabinet 1 or the side of the bed board facing away from the cabinet 1, and the second unlocking part is exposed on the side of the bed board facing away from the cabinet 1 or the outer surface of the table frame 3. The first unlocking part and the second unlocking part enable the first locking member 25 and the second locking member 35 to still be unlocked normally in the power-off state, ensuring the reliability of the folding furniture.

[0053] like Figure 3 , Figure 6 and Figure 7 As shown, in this embodiment, the bed frame 2 has a receiving groove 211 on its base plate 21, and a slide rail 36 is provided in the receiving groove 211. The length direction of the slide rail 36 is parallel to the length direction of the bed frame 2. A first slider 361 is slidably mounted on the slide rail 36. The table frame 3 includes a table board 31 and a support rod 32. A frame 33 is fixedly installed at the bottom of the table board 31. The upper end of the frame 33 is hinged to the first slider 361 so that the upper end of the bed frame 2 can slide along the slide rail 36 with the first slider 361. One end of the support rod 32 is hinged to the bottom of the receiving groove 211, and the other end is hinged to the frame 33. A second locking hole 332 is located at the end of the frame 33 near the first slider 361, and a third locking hole 322 is provided on one side of the support rod 32.

[0054] As Figure 3 shown, when the table frame 3 is in the storage state in the embodiment, the first sliding block 361 is at the top end of the slide rail 36, the support rod 32 and the frame 33 are in the same plane and are hidden in the accommodating groove 211, and the locking tongue of the second locking piece 35 extends into the third lock hole 322; after the table frame 3 is unlocked, the first sliding block 361 slides downward along the slide rail 36, thereby gradually lowering the upper end of the table plate 31, in the lowering process, the table plate 31 rotates upward around the first sliding block 361, the lower end of the table plate 31 gradually moves away from the bed frame 2 and rises, and the support rod 32 is also opened with the table plate 31; when the table plate 31 reaches the horizontal state, the locking tongue of the second locking piece 35 extends into the second lock hole 332, thereby achieving the locking of the table frame 3; one end of the support rod 32 is connected to the bed frame 2, and the other end is connected to the bottom of the table plate 31 and supports the table frame 3; at this time, the support rod 32, the table plate 31 and the bed frame 2 form a stable triangular structure, so that the connection between the table plate 31 and the bed frame 2 remains stable, reducing the possibility of shaking of the table plate 31 in use, which helps to improve the user's experience; in addition, the use of the table leg can be saved through the support frame, the space occupied by the entire table frame 3 is reduced, and the table frame 3 can be better stored in the bed frame 2; secondly, the support rod 32 rotates with the rotation of the table plate 31, without manual operation, so that the unfolding and storage of the table frame 3 are more simple and convenient, which helps to improve the unfolding and storage efficiency of the table frame 3 and can improve the user's experience; in addition, in the unfolding process of the table plate 31, the upper end of the table plate 31 descends with the first sliding block 361, so that the table plate 31 can stop at a height suitable for the user to use after being kept horizontal, and therefore the length of the table plate 31 has less influence on the parking height of the table plate 31, thereby effectively increasing the length of the table plate 31, making the table plate 31 have a larger placing area, and helping to improve the practicality of the table plate 31.

[0055] As Figure 7 shown, two slide rails 36 are arranged on the bed frame 2 in the embodiment, the table frame 3 includes two support rods 32, and the frame 33 includes three cross beams 331, two of which are distributed along the length direction of the table frame 3, and the other cross beam 331 is fixed between the other two cross beams 331, and the cross beam 331 is also between the two slide rails 36; the end of the cross beam 331 forms the second lock hole 332, and the two support rods 32 are fixedly connected with a connecting rod 321, and the third lock hole 322 is located at the end of the connecting rod 321; the use of two slide rails 36 can keep the table plate 31 stable when the first sliding block 361 slides, thereby reducing the possibility of deflection of the table plate 31, and the two support rods 32 can improve the support force on the table plate 31, so that the table plate 31 has stronger load-bearing performance.

[0056] The second lock hole 332 in the embodiment is locked with the second locking piece 35 after the cross beam 331 is lowered along the slide rail 36, and thus the upper surface of the locking tongue of the second locking piece 35 is provided with a first guide slope. During the locking process, the cross beam 331 pushes the locking tongue to retract through the first guide slope, so that the cross beam 331 can pass the locking tongue, and the locking tongue extends into the second lock hole 332. Although the locking tongue of the second locking piece 35 can limit the upward sliding of the cross beam 331 along the slide rail 36, the cross beam 331 can still slide downward along the slide rail 36 due to the first guide slope. The desk board 31 is prone to tilting due to accidental pressing by the user. Therefore, the slide rail 36 is provided with a limiting block 362 in the embodiment. When the second locking piece 35 is locked with the second lock hole 332, the limiting block 362 abuts against the lower side of the sliding block, thereby limiting the continuous downward sliding of the sliding block, ensuring that the upper end of the desk board 31 does not continue to slide downward along the slide rail 36 after the desk board 31 is kept horizontal, and enabling the desk board 31 to be stably kept horizontal. This avoids tilting of the desk board 31 due to accidental pressing by the user, and makes the use of the desk frame 3 more safe and reliable. In addition, the third lock hole 322 is locked with the second locking piece 35 after the support rod 32 is rotated toward the bed frame 2. Thus, the side of the locking tongue of the second locking piece 35 facing the support rod 32 is provided with a second guide slope. During the locking process, the connecting rod 321 pushes the locking tongue to retract through the second guide slope, so that the connecting rod 321 can pass the locking tongue, and the locking tongue extends into the third lock hole 322. The first guide slope and the second guide slope can make the second locking piece 35 enter the second lock hole 332 or the third lock hole 322 more labor-saving, and less prone to jamming. In addition, the locking can be completed without manual operation of the second locking piece 35.

[0057] As shown in Figure 6 , the desk frame 3 in the embodiment further includes a first power assisting device 34. The two ends of the first power assisting device 34 are respectively hinged to the frame 33 and the support rod 32. The first power assisting device 34 is a pneumatic spring. During the transition of the desk board 31 from the unfolded state to the storage state, the pneumatic spring gradually elongates. Since the pneumatic spring itself has the power of gradually elongating, the first power assisting device 34 can provide power assistance for the storage of the desk frame 3. The use of the electric device can be omitted, the structure of the desk frame 3 is simpler, and the external force required by the user to store the desk frame 3 can be saved. In addition, the first power assisting device 34 can also provide damping when the desk board 31 is unfolded, so as to slow down the descending speed of the upper end of the desk board 31, avoid the rapid descending of the upper end of the desk board 31 to the lowest position, and reduce the possibility of the user being bumped by the desk board 31. This helps to improve the use safety of the desk board 31.

When the bed frame 2 is turned over upward, the pneumatic spring is elongated, so that the second power assisting device 16 can provide power when the bed frame 2 is stored upward, reduce the load of the driving mechanism 4, and also reduce the external force required by the user when manually overturning, so that the overturning of the bed frame 2 is more simple and labor-saving. When the bed frame 2 is turned over downward, the second power assisting device 16 can generate damping to slow down the speed of the downward turning of the bed frame 2, avoid the bed frame 2 from colliding with the cabinet 1 or the bottom surface due to the too fast downward turning speed of the bed frame 2, and also prevent the bed frame 2 from causing harm to the user, so that the use of the bed frame 2 has higher safety. In addition, the driving mechanism 4 and the second power assisting device 16 are respectively located on the two sides of the bed frame 2, so that the stress of the bed frame 2 is more uniform, avoiding the bed frame 2 from being damaged due to stress concentration, and making the overturning of the bed frame 2 more stable and reliable.
