Description

Technical Field

[0001] This utility model belongs to the field of furniture technology, and more specifically it relates to a single bed that can be quickly folded up and unfolded. Background Technology

[0002] With the increasing popularity of single-person households and small apartments, the demand for single beds that are space-efficient and easy to move is growing.

[0003] Traditional fixed beds, while structurally stable and with good load-bearing capacity, are bulky and extremely inconvenient to move and transport. They are also prone to collisions in narrow hallways or rooms, making them unsuitable for the needs of modern mobile lifestyles and compact living spaces. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a single bed that can be quickly folded up and unfolded, which has the advantage of solving the problem of the large space occupied by traditional single beds.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A single bed that can be quickly folded up includes a bed frame body and support legs. The bed frame body includes a first frame and a second frame connected by hinges. Guide rails are provided on the opposite outer walls of the first frame and the second frame, and the guide rails have strip-shaped openings that extend through their length. The bed frame body is equipped with a support linkage assembly, which includes a first link, a second link, and a third link that are rotatably connected in sequence by a pin; the end of the first link away from the second link is fixedly connected to a transmission roller. The first frame is equipped with a drive motor, and the output end of the drive motor is connected to the transmission roller to drive it to rotate; The second and third connecting rods are both provided with guide grooves, the openings of the guide grooves face the bed frame body, and a T-shaped slider is slidably connected in the guide groove. The head of the T-shaped slider is embedded in the guide rail, and the neck of the T-shaped slider passes through the strip opening and can slide along it. The support legs are detachably mounted to the bottom of the bed frame body.

[0006] The advantages of this solution are at least as follows: Through the coordinated action of the drive motor, transmission rollers, and supporting linkage assembly, users can automatically unfold and retract the supporting linkage assembly simply by operating a switch, greatly saving manpower and time. The operation is effortless, convenient, and enhances the user experience. The supporting linkage assembly (first, second, and third linkages) forms a stable linkage mechanism. Driven by the motor, the T-shaped slider slides precisely along the guide rail, ensuring that the bed frame can be quickly positioned and locked when unfolded, providing stable support; it can be smoothly retracted when folded, with a controllable and reliable movement trajectory. The first and second frames can be folded in half, and the supporting linkage assembly can be retracted via the drive motor, significantly reducing the volume of the single bed in its retracted state. This solves the pain points of traditional integrated beds, such as difficulty in transportation and large space occupation, making it particularly suitable for small apartments, dormitories, or scenarios requiring frequent movement.

[0007] The present invention is further configured such that the support leg and the bed frame body are detachably connected by a threaded connection.

[0008] The advantages of this solution are at least as follows: the support legs are connected to the bed frame body by a threaded connection, requiring no special tools, and users can easily install and disassemble them, thus improving ease of use.

[0009] The present invention is further configured such that a friction pad is provided on the bottom surface of the support foot.

[0010] The advantages of this design are at least as follows: the friction pads at the bottom of the support feet increase friction with the ground, effectively preventing the bed from sliding or shifting during use and improving safety.

[0011] The present invention is further configured such that: a control module is fixed to the side of the drive motor, and the control module is electrically connected to the drive motor.

[0012] The advantages of this solution are at least as follows: the control module is electrically connected to the drive motor, allowing users to control the extension and retraction of the supporting linkage assembly via buttons, remote control, or smart devices, thereby achieving automated operation and improving the user experience.

[0013] The present invention is further configured such that the outer cover of the drive motor is provided with an isolation sleeve.

[0014] The advantages of this solution are at least as follows: the isolation sleeve covering the drive motor can effectively prevent dust, moisture, and foreign objects from entering, extend the service life of the motor, and also prevent users from directly contacting the motor, reducing the risk of electric shock.

[0015] The present invention is further configured such that a rubber gasket is added to the threaded connection between the support leg and the bed frame body.

[0016] The advantages of this solution are at least as follows: the rubber gasket acts as a buffer at the threaded connection, reducing loosening and vibration at the connection point, and improving the stability and comfort of the bed.

[0017] The present invention is further configured such that: a fine-tuning hole for applying force to the tool is provided on the column of the support foot.

[0018] The advantages of this design are at least as follows: the fine-tuning holes on the support legs allow for precise adjustments using tools, ensuring that the support legs are securely installed and the bed is level, thus enhancing stability. It also facilitates tightening or replacing the support legs after long-term use, extending the bed's lifespan.

[0019] The present invention is further configured such that: elastic protective strips are attached to the end edges of the first frame and the second frame that are close to each other.

[0020] The advantages of this solution are at least as follows: the elastic guard strips attached to the edge of the frame prevent users from being pinched when unfolding or retracting the bed, thus improving safety. Attached Figure Description

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0024] A single bed that can be quickly folded up, such as Figure 1 As shown, the bed frame includes a main body 1 and support legs 2. The main body 1 includes a first frame 101 and a second frame 102 connected by hinges. Guide rails 3 are provided on the opposite outer walls of the first frame 101 and the second frame 102, and a strip-shaped opening 4 extending through its length is provided on the guide rails 3. The bed frame body 1 is provided with a support link group 5. The support link group 5 includes a first link 501, a second link 502 and a third link 503 that are rotatably connected by a pin in sequence; the end of the first link 501 away from the second link 502 is fixedly connected to a transmission roller. The first frame 101 is equipped with a drive motor 6, and the output end of the drive motor 6 is connected to the transmission roller to drive it to rotate. Guide grooves 301 are provided on both the second link 502 and the third link 503 (see reference). Figure 7 The opening of the guide groove 301 faces the bed frame body 1. A T-shaped slider 7 is slidably connected in the guide groove 301. The head of the T-shaped slider 7 is embedded in the guide rail 3. The neck of the T-shaped slider 7 passes through the strip opening 4 and can slide along it. The support leg 2 is detachably installed at the bottom of the bed frame body 1. Through the coordinated action of the drive motor 6, transmission rollers, and support linkage group 5, the user can automatically unfold and retract the support linkage group 5 simply by operating a switch, greatly saving manpower and time, making operation effortless and convenient, and improving the user experience; the support linkage group 5 (first, second, and third linkages 503) constitutes a stable linkage mechanism. Driven by the motor, the T-shaped slider 7 slides precisely along the guide rail 3, ensuring that the bed frame can be quickly positioned and locked when unfolded, providing stable support; when folded, it can be smoothly retracted, with controllable and reliable movement trajectory; the first frame 101 and the second frame 102 can be folded in half, and the support linkage group 5 can be retracted through the drive motor 6, which significantly reduces the volume of the single bed in the retracted state, solving the pain points of traditional integrated bed frames being difficult to move and occupying a lot of space, making it particularly suitable for small apartments, dormitories, or scenarios that require frequent movement.

[0025] like Figure 1 As shown, the support leg 2 is detachably connected to the bed frame body 1 via a threaded connection. This threaded connection allows for easy installation and removal by the user without the need for special tools, improving usability.

[0026] like Figure 1 As shown, the bottom surface of the support leg 2 is provided with a friction pad 8. The friction pad 8 at the bottom of the support leg 2 increases the friction with the ground, effectively preventing the bed from sliding or shifting during use and improving safety.

[0027] like Figure 4 As shown, a control module 9 is fixed to the side of the drive motor 6, and the control module 9 is electrically connected to the drive motor 6. The control module 9, being electrically connected to the drive motor 6, allows users to control the extension and retraction of the supporting linkage group 5 via buttons, remote control, or smart devices, achieving automated operation and improving the user experience.

[0028] like Figure 4 As shown, the drive motor 6 is covered by an isolation sleeve 10. The isolation sleeve 10 covers the drive motor 6, which can effectively prevent dust, moisture and foreign objects from entering, extend the service life of the motor, and also prevent users from directly contacting the motor, reducing the risk of electric shock.

[0029] like Figure 2 As shown, a rubber washer 11 is installed at the threaded connection between the support leg 2 and the bed frame body 1. The rubber washer 11 acts as a buffer at the threaded connection, reducing loosening and vibration of the connection, and improving the stability and comfort of the bed.

[0030] like Figure 2 As shown, the support leg 2 has a fine-tuning hole 12 on its column for applying force with tools. The fine-tuning hole 12 on the support leg 2 column allows for fine adjustment using tools, ensuring that the support leg 2 is securely installed and the bed is level, enhancing stability, and facilitating the tightening or replacement of the support leg 2 after long-term use, thus extending the service life of the bed.

[0031] like Figure 5 As shown, both the first frame 101 and the second frame 102 have elastic guard strips 13 attached to their adjacent end edges. The elastic guard strips 13 are attached to the edges of the frames to prevent users from being pinched when setting up or folding up the bed, thus improving safety.

[0032] The working process and beneficial effects of this utility model are as follows: When the single bed of this utility model needs to be stored, the drive motor 6 is started by the control module 9. The drive motor 6 drives the transmission roller to rotate, causing the first connecting rod 501 fixed on it to rotate upward. The movement of the first connecting rod 501 is linked to the second connecting rod 502 and the third connecting rod 503 through the pin shaft, so that the included angle between the two becomes smaller. At the same time, the T-shaped slider 7 slides along the guide rail 3 towards the first connecting rod 501 under the constraint of the guide groove 301. This process ensures that the supporting linkage 5 always moves along the preset trajectory when retracting, avoiding jamming or deviation, so that the linkage assembly can be smoothly and compactly retracted into the bed frame body 1, thereby retracting the supporting linkage 5 as a whole; then, the second frame 102 is flipped downward around the hinge, so that it is folded and fitted with the first frame 101; finally, the bed frame body 1 and the retracted supporting linkage 5 form a compact whole, significantly reducing the area occupied in the idle state; the support legs 2 can also be easily unscrewed, further reducing the volume.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.
