Technical Field

[0001] This utility model belongs to the field of furniture technology, specifically relating to a rocking bed. Background Technology

[0002] A bed is a piece of furniture closely related to people's daily lives, effectively ensuring their need for rest. However, existing beds are all flat and fixed, which can only be used in normal environments. When used in swaying environments such as long-distance buses or ships, people will roll back and forth on the bed, affecting their rest. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a rocking bed that can adjust the bed board in a shaking environment, reduce the shaking of the bed board, and prevent the user from shaking with the bed and affecting sleep quality.

[0004] To achieve the above and other related objectives, this utility model provides a rocking-damping bed, comprising an outer frame, an inner frame, a bed board, and bed legs located at the four corners of the bottom of the outer frame; the outer frame, inner frame, and bed board are all centrally symmetrical structures; the inner contour shape of the outer frame is the same as the outer contour shape of the inner frame; the outer contour shape of the bed board is the same as the inner contour shape of the inner frame; the inner frame is rotatably assembled inside the outer frame about the transverse centerline of the outer frame as the axis of rotation, and the bed board is rotatably assembled inside the inner frame about the longitudinal centerline of the inner frame as the axis of rotation; the rocking-damping bed further includes a stop yoke mechanism disposed below the center of the bed board, the stop yoke mechanism including support The support frame comprises a frame, a fixed shaft, a turntable, a sliding pin, and a sliding yoke. The support frame includes a mounting plate fixed to the bottom of the bed board and sliding grooves located at both ends of the mounting plate. One end of the fixed shaft is vertically fixed to the center of the bottom of the bed board, and the other end of the fixed shaft passes through the mounting plate and is rotatably connected to the center of the turntable. A sliding pin is eccentrically provided on the turntable, and the sliding yoke has a yoke groove that slides with the sliding pin. Sliding rods that slide with the corresponding sliding grooves are provided on both sides of the sliding yoke. When the external frame shakes with the external environment, the turntable and sliding pin assembly will rotate relative to the fixed shaft under its own weight, causing the sliding yoke to perform linear reciprocating motion driven by the sliding pin, thereby adaptively generating resistance to reduce the shaking force and reduce the degree of bed board shaking.

[0005] Preferably, the mounting plate is provided with limiting springs that are connected to the four bed legs respectively, so that when the external frame sways with the external environment, the limiting springs generate a pulling force to reduce the swaying force. This pulling force, together with the resistance force generated by the stop yoke structure, counteracts the swaying force and ensures the balance of the bed board.

[0006] Preferably, a shock-absorbing spring is provided between the mounting plate and the ground to improve user comfort.

[0007] Preferably, both the outer frame and the inner frame are rectangular frames, and the bed board is a cuboid. The four corners of the outer frame, the inner frame, and the bed board are rounded to reduce friction when the outer frame, the inner frame, and the bed board rotate relative to each other.

[0008] Preferably, a transverse rotating shaft is fixed on the long side frame of the inner frame, and a universal ball is provided at the outer end of the transverse rotating shaft. A universal ball groove that mates with the universal ball on the transverse rotating shaft is provided on the long side frame of the outer frame. A longitudinal rotating shaft is fixed on the short side of the bed board, and a universal ball is provided at the outer end of the longitudinal rotating shaft. A universal ball groove that mates with the universal ball on the longitudinal rotating shaft is provided on the short side frame of the inner frame. Rolling rotation is achieved through the cooperation of the universal ball and the universal ball groove to ensure smooth rotation.

[0009] Preferably, the outer frame is equipped with guardrails to prevent users from rolling off the bed board and falling and getting injured.

[0010] Preferably, the anti-shaking bed includes a locking device for locking the outer frame, the inner frame, and the bed board relative to each other.

[0011] As described above, the anti-shaking bed of this utility model has the following beneficial effects:

[0012] The rotational assembly between the outer frame, inner frame, and bed board enables the longitudinal swing (i.e., back-and-forth swing) of the inner frame relative to the outer frame and the lateral swing (i.e., left-and-right swing) of the bed board relative to the inner frame. The stop yoke structure and limit rope under the bed board counteract the swaying forces in different directions generated by the swaying environment on the bed board, thereby achieving automatic straightening of the bed board.

[0023] The inner frame 3 is rotatably assembled inside the outer frame 2 with the transverse center line a as the axis of rotation, and the bed board 4 is rotatably assembled inside the inner frame 3 with the longitudinal center line b as the axis of rotation.

[0024] The stop yoke mechanism includes a support frame, a fixed shaft 52, a turntable 53, a sliding pin 531, and a sliding yoke 54. The support frame includes a mounting plate 511 fixed to the bottom of the bed board 4 and sliding grooves 512 located at both ends of the mounting plate 511. One end of the fixed shaft 52 is vertically fixed to the center of the bottom of the bed board 4, and the other end of the fixed shaft 52 passes through the mounting plate 511 and is rotatably connected to the center of the turntable 53. A sliding pin 531 is eccentrically provided on the turntable 53, and the sliding yoke 54 has a yoke groove that slides with the sliding pin 531. Sliding rods 541 that slide with the corresponding sliding grooves 512 are provided on both sides of the sliding yoke 54.

[0025] It is understood that the shapes of the outer frame 2, the inner frame 3 and the bed board 4 can be determined according to actual needs and are not limited thereto. In this embodiment, the outer frame 2 and the inner frame 3 are preferably set as rectangular frames and the bed board 4 is set as a cuboid. In order to reduce friction and improve aesthetics, the four corners of the outer frame 2, the inner frame 3 and the bed board 4 are rounded.

[0026] It is understood that the rotational assembly between the inner frame 3 and the outer frame 2, and the rotational assembly between the inner frame 3 and the bed board, can be smoothly rotated by means of a rotating shaft + bearing or universal ball + universal ball groove, etc., and there is no limitation thereto. In this embodiment, the rotational method of universal ball + universal ball groove is preferred.

[0027] Specifically, such as Figure 1 As shown, a transverse rotating shaft 31 is fixed on the long side frame of the inner frame 3, and a universal ball 7 is provided at the outer end of the transverse rotating shaft 31. A universal ball groove 71 that mates with the universal ball 7 on the long side frame of the outer frame 2 is provided. A longitudinal rotating shaft 41 is fixed on the short side of the bed board 4, and a universal ball 7 is provided at the outer end of the longitudinal rotating shaft 41. A universal ball groove 71 that mates with the universal ball 7 on the short side frame of the inner frame 3 is provided.

[0032] When in use, the user lies flat on the bed board 4. When there is no vibration in the external environment, the locking mechanism locks the outer frame 2, the inner frame 3, and the bed board 4 together. The shock-absorbing spring is used to improve the user's comfort. When the external environment shakes, the locking mechanism is removed, and the bed board 4 and the stop yoke mechanism shake with the external environment. At this time, the turntable 53 in the stop yoke mechanism rotates under its own weight, causing the slide rod 541 to move back and forth, generating a resistance force to suppress the shaking of the bed board 4 and reducing the shaking angle of the bed board 4. The setting of the limit spring 6 further reduces the shaking angle of the bed board 4, ensuring that the bed board 4 remains balanced in the shaking environment.
