[0025] The following will clearly and completely describe the related technologies in the present utility model in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present utility model without making creative efforts shall fall within the protection scope of the present utility model.
[0026] Referring to Figures 1 to 5 , an upper berth for an automobile with a segmented winding and retraction of bent wire mesh in this embodiment includes: a berth cover with a protective net assembly 1, and the berth cover with a protective net assembly 1 includes: a berth frame 2, a lower sponge 3, and a sling 9; one long side of the berth cover with a protective net assembly 1 is rotationally connected to the inner wall of the automobile carriage through a shaft, the bottom of the sling 9 is hoisted on the other long side of the berth cover with a protective net assembly 1, and the top of the sling 9 is hoisted on the top of the automobile carriage; the berth frame 2 is a concave trough shape, the lower sponge 3 is sunken and installed in the lower trough shape of the berth frame 2, and the bottom surface and / or side surface of the lower trough shape of the berth frame 2 is grille-shaped or hollow-shaped; the sling 9 is made of a flexible rope with an adjustable hoisting length; a rigid metal frame can be arranged around the berth cover with a protective net assembly 1, and then the edge of the berth frame 2 is welded to the metal frame, so that the periphery of the berth frame 2 has better rigidity and better elasticity inside. Moreover, since the lower sponge 3 is sunken and installed in the lower trough shape of the berth frame 2, the comfort of the berth frame 2 is improved.
[0027] Furthermore, at the connection between the sling 9 and the berth cover with a protective net assembly 1, there is a cylindrical aluminum alloy sleeve 6 with a horizontal rotating shaft. Inside the aluminum alloy sleeve 6, there is a retractor assembly 7 that rotates coaxially with the aluminum alloy sleeve 6. The lower end of the sling 9 is wound and fixed on the rotating shaft of the retractor assembly 7; a return spring is also arranged on the rotating shaft of the retractor assembly 7. The sling 9 is wound around the rotating shaft of the retractor assembly 7. When the berth cover with a protective net assembly 1 is rotated upward to be retracted, the return spring returns to its original position, the rotating shaft rewinds the lower end of the sling 9, and the sling 9 is coiled and contracted inside the aluminum alloy sleeve 6; when the berth cover with a protective net assembly 1 is rotated downward to be laid flat, the sling 9 is stretched out from the aluminum alloy sleeve 6, and the return spring is compressed by the force, storing energy for the next upward rotation to retract the berth cover with a protective net assembly 1; the aluminum alloy sleeve 6 with a horizontal rotating shaft has a lower cost than the existing straight-through aluminum alloy sleeve and better retracting and releasing effects.
[0028] Even further, at the edge of the berth frame 2, there is a notch 11 that is recessed inward in the horizontal direction, and the aluminum alloy sleeve 6 is snap-fitted and fixedly connected in the notch 11; the aluminum alloy sleeve 6 is arranged in the notch 11, making the outer edge of the berth cover with a protective net assembly 1 flatter and less likely to interfere with external space equipment or personnel during retraction and release.
[0029] Furthermore, a release button 5 is inserted through the outer wall of the aluminum alloy sleeve 6. One end of the release button 5 located inside the aluminum alloy sleeve 6 is interlocked with the rotating shaft of the retractor assembly 7. The release button 5 is interlocked with the rotating shaft, functioning to lock the return spring. When the release button 5 is in the un-pressed position, the return spring is locked, and the elastic force of the return spring cannot be transmitted to the rotating shaft. When the sleeper belt protection net assembly 1 is laid flat, it will not be retracted due to the elastic force causing the rotating shaft to coil the sling 9. When it is necessary to rotate and retract the sleeper belt protection net assembly 1, press the release button 5, the return spring is unlocked, and the elastic force causes the rotating shaft to coil the sling 9, thereby causing an upward pulling force on the outside of the sleeper belt protection net assembly 1. The vehicle occupants only need to gently push up the sleeper belt protection net assembly 1 to easily retract it.
[0030] Further, a buckle 10 for adjusting the length is inserted through the sling 9; the buckle 10 is used to adjust the length of the sling 9 so that when the sling 9 is straightened, the sleeper belt protection net assembly 1 is horizontal or maintains a certain slope according to the habits of the vehicle occupants.
[0031] Further, at least two slings 9 are provided; the two slings 9 can lift the sleeper belt protection net assembly 1 more reliably and securely.
[0032] Further, an upper sponge 4 is also covered on the upper part of the lower sponge 3, and the four peripheral edges of the upper sponge 4 respectively extend out of the four peripheral edges of the sleeper frame 2; the upper sponge 4 and the lower sponge 3 are used in combination, increasing the sponge thickness of the sleeper belt protection net assembly 1 on the premise of the same total thickness, thus improving the comfort of the sleeper on the vehicle.
[0033] Further, a support rod 8 is rotatably connected to the sleeper frame 2, and a hook or buckle is provided at one end of the support rod 8 away from the sleeper frame 2; the support rod 8 is used to reliably fix the sleeper belt protection net assembly 1 inside the vehicle body when it is rotated and retracted. The hook or buckle at the other end of the support rod 8 detachably connects the support rod 8 to the inner wall of the vehicle body, thereby fixing the sleeper belt protection net assembly 1.
[0034] Furthermore, the support rod 8 is a rod with adjustable length; the support rod 8 with adjustable length enables the rotation and retraction angle of the sleeper belt protection net assembly 1 to be adjustable and controllable, meeting the diverse needs of vehicle occupants for the retraction angle of the sleeper belt protection net assembly 1; at the same time, it enables vehicle occupants to place items on the sleeper belt protection net assembly 1 that is not fully retracted.
[0035] Further, the sleeper belt protection net assembly 1 is in a cuboid shape.
[0036] Embodiment
[0037] The sleeper frame 2 of this embodiment is a sunken groove made of welded steel wire grids. Assembly process description: After cutting the transverse and longitudinal steel wires to the required lengths, bend the two ends of the steel wires; place the bent steel wires in the tooling and arrange them at a fixed spacing to firmly weld the contact points of the transverse and longitudinal steel wires; then place the welded steel wire mesh into the frame formed by profile bending and welding, and weld the contact points between the perimeter of the steel wire mesh and the skeleton; screw and install the retractor assembly 7 (including the release button 5) in the two notches 11 at the front end of the sleeper; sequentially place the lower sponge 3 and the upper sponge 4 in the frame, and then integrally wrap the sleeper with a leather belt and a protective net assembly 1; finally, pass the plastic-sprayed seamless pipe through the belt clips of the retractor assembly 7, the upper end of the protective net, and the belt clips of the retractor assembly 7, and press the two ends into the end caps, and the assembly of the upper sleeper assembly is completed.
[0038] Instructions for using the upper sleeper assembly: The rear end of the upper sleeper assembly is fixed to the body hinge of the vehicle body, and brackets are provided on both sides of the vehicle body for support. The upper end of the sling 9 of the retractor assembly 7 is screwed and fixed to the roof sheet metal; open the clamping mechanism of the sling 9 bracket, lift the upper sleeper assembly, and the retractor automatically retracts to realize the upward rotation of the sleeper to release the interior space of the vehicle; press the release buttons 5 on both sides, the retractor is released from the limit, and due to gravity, the upper sleeper rotates downward to the support position of the bracket, and pull up the protective net and the plastic-sprayed seamless steel pipe, and lock the locking mechanism of the strap bracket.
[0039] Therefore, in this embodiment, the bearing capacity of the steel wire mesh of the upper sleeper is strengthened after bending, the filling space of the sponge is increased, and the comfort of the sleeper is improved; the automatic retraction mechanism is divided into two sections, and the short aluminum profile sleeve is screwed to the iron skeleton body through the profile fixing plate, reducing the usage amount of the integral aluminum profile sleeve, so the weight of the sleeper itself is also reduced; the weight of the bent steel wire mesh segmented retractable upper sleeper on the vehicle is lower than that of the integral aluminum alloy sleeper, and the sleeper can be pushed up with one hand, and the automatic retraction is realized by using the retractor installed inside the profile. Press the release button, and the sleeper can be lowered and laid flat.
[0040] In summary, the steel wire mesh proposed by the present utility model is bent and then welded to the frame, expanding the sponge filling space and improving the comfort. At the same time, on the basis of realizing automatic retraction, the present utility model reduces the material usage amount of the aluminum alloy sleeve, and the cost is lower than that of the straight-through aluminum alloy sleeve.
[0041] It should be emphasized that: The above are only the preferred embodiments of the present utility model, and do not impose any form of limitation on the present utility model. Any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
