[0024] The following is a detailed description of the embodiments of the utility model in conjunction with the accompanying drawings. It should be clear that the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1-6 As shown, in some illustrative embodiments, a pull-out berth for a heavy-duty commercial truck is provided, comprising: a front berth assembly, a rear berth assembly, a guide support assembly, an additional middle berth cushion 1, a pull-out handle 2 and a support rod 3.

[0026] The rear bed assembly is connected to the vehicle body through a rotating bracket 4, so that the rear bed assembly can be turned over in the cab for storage. The rotating bracket 4 adopts a rotating shaft limiting structure, which is a common mechanical structure. Its function is to protect the rear bed assembly from excessive rotation due to some reasons, and at the same time, it plays the role of supporting the rear bed assembly. The front bed assembly is located in front of the rear bed assembly and is connected to the rear bed assembly through a guide support component, so that the front bed assembly can be translated to the front of the rear bed assembly, thereby realizing the widening of the bed width of this embodiment.

[0027] The rear berth assembly is composed of a rear berth support plate 5 and a rear berth mat 6, wherein both ends of the rear berth support plate 5 are connected to the vehicle body through a rotating bracket 4, and the rear berth mat 6 is arranged on the upper surface of the rear berth support plate 5. The front berth assembly is composed of a front berth support plate 7 and a front berth mat 8 arranged on the upper surface of the front berth support plate 7.

[0028] The front berth support plate 7 is connected to the rear berth support plate 5 through a guide support assembly. The guide support assembly includes: two sets of linear slide rails 9 arranged in parallel, the guide members of the linear slide rails 9 are connected to the bottom of the rear berth support plate 5, and the moving members of the linear slide rails 9 are connected to the bottom of the front berth support plate 7. The linear slide rails 9 allow the front berth assembly to be stably translated in front of the rear berth assembly, and the berth can be widened when translated outward, and can be stored when translated inward.

[0029] The front berth support plate 7 and the rear berth support plate 5 face each other on one side, and a mutually meshing sawtooth structure 10 is provided. Among them, the sawtooth structure 10 is a sawtooth-like structure, and the sawtooth shape is usually used to describe a tooth-like shape or pattern, with a regular and repetitive concave-convex structure. The sawtooth structure 10 of this embodiment can adopt a rectangular sawtooth shape or an isosceles trapezoidal sawtooth shape. Meshing refers to the process of two or more objects crossing, biting or connecting with each other due to the characteristics of their shape or structure. The mutual meshing of the sawtooth structure 10 of this embodiment means that the protruding tooth structure on the front berth support plate 7 can be embedded in the recessed notch on the rear berth support plate 5, and correspondingly, the protruding tooth structure on the rear berth support plate 5 can be embedded in the recessed notch on the front berth support plate 7.

[0030] The mattress of the pull-out berth of the present embodiment adopts a block-type structure, specifically three pieces, namely the front berth pad 8, the additional middle berth pad 1 and the rear berth pad 6. When driving, the berth is in a contracted state, at which time only the front berth pad 8 and the rear berth pad 6 are installed. When parking and resting, the berth is in a stretched state, at which time the three mattresses are arranged in parallel and all put into use. When it is necessary to widen the berth, the front berth support plate 7 is pulled outward (i.e., in front of the rear berth assembly) so that the rear berth pad 6 and the front berth pad 8 are separated from each other and form a space, which is used to place the additional middle berth pad 1, that is, the additional middle berth pad 1 is arranged between the rear berth pad 6 and the front berth pad 8, and they are assembled together to form the mattress of the pull-out berth of the present embodiment. The additional middle berth cushion 1 is located above the sawtooth structure 10 , and the sawtooth structure 10 on the rear berth support plate 5 and the front berth support plate 7 jointly supports the additional middle berth cushion 1 , which is beneficial to the support of the additional middle berth cushion 1 .

[0031] The pull handle 2 is connected to the moving parts of the linear slide rail 9, and the pull handle 2 is located below the front berth support plate 7. The front berth assembly can be pulled horizontally by pulling the pull handle 2, which is convenient for operation. The pull handle includes: a U-shaped rod 201 and a pull ring 202 arranged on the U-shaped rod 201. The two ends of the U-shaped rod 201 are respectively connected to the moving parts of the two sets of linear slide rails, and the pull ring 202 is the operating end of the pull handle 2.

[0032] An extension plate 701 is arranged at the front middle position of the front berth support plate 7, a clearance groove 702 is arranged at the bottom of the extension plate 701, and the top end of the support rod 3 is hinged to the bottom of the clearance groove 702. The support rod 3 is used to support the front berth assembly, and the design of the extension plate 701 can provide a mounting platform for the support rod 3, and the clearance groove 702 can provide an installation space for the hinge seat used for the hinge. When the berth is in a contracted state as a whole, the support rod 3 is folded and attached to the bottom of the berth, and when the berth is in a stretched state as a whole, the support rod 3 is unfolded to provide front end support for the berth.

[0033] The width of the front berth support plate 7 is greater than the width of the rear berth support plate 5, which increases the stability in use.

[0034] The space in the cab is limited, so it is necessary to improve the utilization of the space. According to the situation that the driver and the co-driver mainly use seats when driving, and mainly use berths when parking and resting, the present application adopts a linear slide rail 9. When driving, the berth is in a retracted state, which is a seat avoidance space. When parking and resting, the seat slide rail is adjusted to the berth avoidance space, and the berth is pulled out, so that there is a wider and more comfortable sleeping and resting space. The switching of the two states enables the improvement of space utilization.

[0035] The travel of the berth using sponge stretching in the prior art is limited by the sponge stretching length, while the berth design of the present application is not limited by the sponge stretching length, but only depends on the travel of the linear slide rail 9, and any slide rail travel can be selected to reach the stretching length. In addition, the thickness and hardness of the front berth pad 8, the additional middle berth soft cushion 1 and the rear berth pad 6 are not affected by the stretching, so the state is stable.

[0036] In addition, the present application has the advantage of being lightweight, achieving cost and weight reduction. The front berth pad 8, the additional middle berth cushion 1, and the rear berth pad 6 can be made of ordinary sponges, which are simpler to process than retractable sponges, have lower costs, lower manufacturing difficulty, and higher generalization. Compared with the existing pull-out berth, the present application no longer uses a fixed crossbeam and a retractor, so the weight can be reduced to a certain extent, and the structure is simplified while achieving the same function.

[0037] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
