[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0023] A type of manually adjustable bed, such as Figures 1-5 As shown, the structure includes a first bed 1, a second bed 2, a connecting piece 3, and a lifting assembly 4. The first bed 1 and the second bed 2 are hinged together. The lifting assembly 4 is located on both sides of the carriage and is connected to the second bed 2. The first bed 1 is connected to the end of the carriage via the connecting piece 3. The connecting piece 3 supports the first bed 1 and cooperates with the sloping roof of the carriage. The lifting assembly 4 guides the second bed 2 to move up and down. When unfolded, the second bed 2 moves downward, so that the first bed 1 and the second bed 2 are on the same horizontal plane, forming a large bed. When folded up, the lifting assembly 4 guides the second bed 2 to move upward, so that it is against the roof, forming a horizontal structure. At this time, the first bed 1 and the second bed 2 are set at an angle. Through the above structure, the first bed 1 and the second bed 2 can be stored in the sloping and horizontal parts of the roof, improving the utilization of the top space.

[0024] In one embodiment, such as Figures 1-5 As shown, the lifting assembly 4 includes a fixed base 41, a first bearing seat 42, a second bearing seat 43, a first connecting rod 44, a second connecting rod 45, and a limiting assembly 46. The first bearing seat 42 and the second bearing seat 43 are respectively located at both ends of the fixed base 41. The two ends of the first connecting rod 44 are connected to the first bearing seat 42 and the second bed 2. The two ends of the second connecting rod 45 are connected to the second bearing seat 42 and the second bed 2. The lifting bed's unfolding position is controlled by the limiting assembly 46.

[0025] In one embodiment, such as Figures 1-5 As shown, the limiting component 46 includes a first limiting block 461 and a second limiting block 462. The first limiting block 461 and the second limiting block 462 are respectively disposed on the first bearing seat 42 and the second bearing seat 43, and the first limiting block 461 and the second limiting block 462 rotate synchronously with the first connecting rod 44 and the second connecting rod 45, respectively.

[0026] In the above embodiments, such as Figures 1-5 As shown, a limiting bracket 47 is installed on the fixed base 41, and a third limiting block 48 is provided on the limiting bracket 47 to cooperate with the second limiting block 462.

[0027] When in use, the first limiting block 461 contacts the fixed seat 41 and is supported on the fixed seat 41; the second limiting block 462 contacts the third limiting block 48 and is supported on the third limiting block 48; at this time, the second bed body 2 descends to the lower limit position.

[0028] In one embodiment, such as Figures 1-5 As shown, the first limiting block 461 and the second limiting block 462 are connected by a third link 463. The third link 463 enables the first link 44 and the second link 45 to rotate synchronously.

[0029] In one embodiment, such as Figures 1-5 As shown, the lifting assembly 4 also includes a gas spring 49, which connects to the limiting assembly 46 and the fixed base 41. Specifically, the gas spring 49 connects to the first limiting block 461 and the fixed base 41. When the second bed body 2 is in the folded position, the gas spring 49 is in the extended state; when the second bed body 2 is in the extended position, the gas spring 49 is in the retracted state. That is, the gas spring 49 makes bed retraction easier and more convenient.

[0030] In one embodiment, such as Figures 1-5 As shown, the fixing base 41 has an L-shaped strip structure, and reinforcing plates 411 are installed at both ends. Specifically, the reinforcing plates 411 are right-angled triangles, and the base plate and side plate of the fixing base 41 are connected by the reinforcing plates 411 to increase the strength of the fixing base 41.

[0031] In one embodiment, such as Figures 1-5 As shown, the connector 3 includes a winder 31 and a connecting belt 32. The winder 31 is connected to the carriage, and the connecting belt 32 connects the winder 31 and the first bed 1. The winder 31 pulls the first bed 1 through the connecting belt 32, providing traction to the first bed 1, and thus providing an upward traction force to the first bed 1 when unfolded, so that the first bed 1 and the second bed 2 are on the same horizontal plane.

[0032] In one embodiment, such as Figures 1-5 As shown, a fixing strap 5 is installed on the top of the carriage, and the fixing strap 5 is connected to the second bed 2 by a buckle. The fixing strap 5 is used to secure the bed when it is stored to prevent the bed from unfolding due to vehicle bumps during travel.

[0033] When using this utility model, such as Figures 1-5As shown, during folding, the first bed 1 engages with the sloping roof of the carriage, and the second bed 2 engages with the horizontal top portion of the carriage. The second bed 2 is fixed to the top of the carriage via a fixing strap 5. During unfolding, the fixing strap 5 is first separated from the second bed 2, and the second bed 2 is pulled downwards. The first connecting rod 44 and the second connecting rod 45 rotate around the first bearing seat 42 and the second bearing seat 43 respectively, until the first limiting block 461 and the second limiting block 462 reach their limit positions. At this point, the second bed 2 is at its lower limit position. The first bed 1 is connected to the winding device 31 via a connecting strap 32. The winding device 31 provides traction to the first bed 1, allowing it to unfold and connect with the second bed 2 to form a single bed. During unfolding, the gas spring 49 is compressed. During folding, only the second bed 2 needs to be pushed upwards, with the gas spring 49 providing auxiliary force. Then, the fixing strap 5 is connected to the buckle on the second bed 2 to lock it in place.

[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of implementation of the present utility model. Any modifications or equivalent substitutions to the present utility model without departing from the spirit and scope thereof should be covered within the protection scope of the claims of the present utility model.
