Description
Technical Field
[0001] The present application relates to the technical field of apartment beds, and in particular to an apartment bed and a climbing ladder control method. Background Art
[0002] Among the existing apartment bed technologies, the most common one is the upper bed and lower desk type: there is a bed on the top and a study desk and wardrobe on the bottom, providing users with relatively independent study and storage space, and users climb up the ladder to enter the bed above.
[0003] Traditional climbing ladders have obvious limitations in structural design. The climbing ladder is directly and firmly connected to the bed through welding, bolting, etc. to form an inseparable whole. This fixed connection mode makes it impossible to flexibly disassemble or fold the climbing ladder. Since the traditional climbing ladder lacks the function of disassembly and folding, when the climbing ladder is not needed, such as when students mainly study and move around under the bed during the day, the climbing ladder still exists abruptly in the space, occupying the relatively limited dormitory space. This not only affects the freedom of movement in the room, but also may cause a sense of visual congestion, making the entire dormitory environment appear messy. Summary of the invention
[0004] In order to solve the problem of space occupation by climbing ladders, the present application provides an apartment bed and a climbing ladder control method.

[0006] By adopting the above technical solution, the climbing ladder moves along the track under the action of the moving mechanism. Since the tracks are respectively arranged at the top and front end of the bed, the climbing ladder changes from a vertical state to a lying state during the movement on the track, and the climbing ladder is stored at the top of the bed. Compared with the traditional outward design of the climbing ladder, the climbing ladder is located between the bed and the track, which makes it easier for users to climb into the rest area and is safer during the climbing process.
[0007] Optionally, the track is fixedly connected to a bracket, and the bracket raises the distance between the track and the top of the bed, and the height of the bracket raising is the area where the climbing ladder is stored.

[0012] By adopting the above technical solution, the first motor drives the power gear to rotate. Since the power gear is meshed with the first gear, the rotation of the power gear can drive the power bin to move along the track, and the power bin thereby drives the moving mechanism to move. The two limit rods can now keep the climbing ladder parallel to the track, and the worm gear reducer enables the moving mechanism to have a self-locking function.
[0013] Optionally, a turntable is rotatably connected inside the movable shell, a ring gear is fixedly connected to one side of the turntable, a second motor is fixedly connected to the movable shell, a driving gear meshing with the ring gear is fixedly connected to the output end of the second motor, and the second motor drives the driving gear to rotate through a worm gear reducer.

[0020] By adopting the above technical solution, the moving direction of the climbing ladder is restricted, so that the climbing ladder moves relative to the power box, and the up and down movement of the climbing ladder is achieved through the engagement of the gear and the rack. The wire wheel tightens the steel rope to drive the climbing ladder to retract, which not only realizes the folding of the climbing ladder, but also enables the folded climbing ladder to be stored by moving.
[0021] A climbing ladder control method includes a controller, which is arranged on the bed guard of an apartment bed. The controller can select three modes: climbing mode, guarding mode and storage mode. The specific implementation method is as follows: Climbing Mode: S11. First, the distance between the track and the entrance to the rest area is adjusted by a power source to provide a suitable distance for the user to climb; S12, the moving mechanism moves to the lowest end along the track, and then rotates the bottom end of the climbing ladder to face the ground; S13, unfolding the climbing ladder through the power box so that the bottom end of the climbing ladder touches the ground.
[0022] Enclosure mode: S21, firstly folding the climbing ladder by means of a power box; S22, the moving mechanism moves to the lowest end along the track; S23, rotating the folded climbing ladder so that the length direction of the climbing ladder is parallel to the ground; S24, finally, adjusting the distance between the track and the entrance to the rest area by means of a power source, so that the climbing ladder and the bed guard together surround the entrance to the rest area; Storage mode: S31, firstly folding the climbing ladder by means of a power box; S32, rotating the folded climbing ladder so that the length direction of the climbing ladder faces the ground; S33, the moving mechanism moves to the top along the track, so that the climbing ladder is located in the storage area at the top of the bed.
[0023] By adopting the above technical solution, the controller selects different modes and uses the coordinated work of the power source, the moving mechanism and the power box to change the position, shape and relative relationship of the climbing ladder with the bed body to achieve the functions of climbing, enclosure and storage. In different modes, the track position is adjusted by the power source, the moving mechanism drives the climbing ladder to move along the track, and the power box realizes the deployment, folding and rotation operations of the climbing ladder, thereby achieving different usage states.

When lying, it can be stored on the top of the bed without taking up too much extra space, solving the problem of inconvenient storage of traditional climbing ladders. When the climbing ladder stands on the ground, it can be used for normal climbing. And its unique design between the bed and the track allows the user to climb with his back to the bed.

[0025] 2. The climbing ladder has multiple control modes. The operation panel has three modes: climbing mode, enclosure mode and storage mode.

[0026] 3. Movement and rotation function of the moving mechanism and climbing ladder: The power gear of the moving mechanism meshes with the first rack of the bending rod. The motor drives the power gear to rotate to drive the moving mechanism to move along the bending rod, and the two limit rods can keep the climbing ladder parallel to the track. The climbing ladder can be moved and folded through the power box. Its turntable design can drive the power box to rotate under the drive of the motor, so that the climbing ladder has the ability to select along the width direction, and the climbing ladder can be turned into a bed guard for enclosure, which increases the flexibility of use.
