[0025] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0026] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 , Figure 16 and Figure 17 As shown, this embodiment provides a pull-rod unlocking upper berth, including a berth body 100, a protective net assembly 200, a retractor 300, and an unlocking component 400; two retractors 300 are fixedly installed on the berth body 100, one end of the protective net assembly 200 is connected to the retractor 300, and the adjusting webbing 230 of the protective net assembly 200 is located at the bottom of the berth body 100; the unlocking component 400 includes an unlocking button 410, an unlocking pull rod 420, and a locking member 430, both ends of the locking member 430 are connected to the retractor 300 through a synchronizing rod 310, and the unlocking button 410 is connected to the locking member 430 through the unlocking pull rod 420.

[0027] Specifically, when the user needs to unfold the protective net assembly, that is, when unfolding the berth body, the user triggers the unlock button 410. The unlock button 410 triggers the unlock lever 420, which in turn triggers the locking member 430. The locking member 430 releases the restriction on the retractor 300, allowing the retractor 300 to unwind. This allows the adjusting webbing 230 of the protective net assembly 200 to stretch outward relative to the retractor 300, so that the adjusting webbing 230 does not restrict the downward rotation of the berth body 100. This allows the user to lay the folded berth body 100 flat. Furthermore, the two retractors 300 work synchronously through the synchronizing rod 310, making operation convenient. The user only needs to control one unlock button 410.

[0028] The adjusting webbing 230 of the protective net assembly 200 is located at the bottom of the berth body 100. When the retractor 300 retracts, the adjusting webbing 230 can support the berth body 100 to be retracted. In normal use, the weight of the berth body 100 falls on the adjusting webbing 230 and the hinge hook seat 150, improving the stability of the berth body 100.

[0029] See Figures 1-17 As shown, in the optional solution of this embodiment, the sleeper body 100 is provided with an unlocking mounting base 101, the unlocking button 410 is rotatably mounted on the unlocking mounting base 101, and a first reset spring member 411 is provided between the unlocking button 410 and the unlocking mounting base 101.

[0030] The locking component 430 includes a locking seat 431, a ratchet 432, a pawl plate 433, and a rotating shaft 434. The rotating shaft 434 is rotatably mounted on the locking seat 431, and the ratchet 432 is sleeved on the rotating shaft 434. The ratchet 432 and the rotating shaft 434 rotate synchronously. The pawl plate 433 is rotatably mounted on the locking seat 431. A second reset spring 435 is provided between the pawl plate 433 and the locking seat 431 so that the pawl plate 433 tends to abut against the ratchet 432. The pawl plate 433 is connected to the unlocking lever 420, which can drive the pawl plate 433 away from the ratchet 432. An angle limiting plate 436 is provided on the locking seat 431 to limit the rotation angle of the pawl plate 433.

[0031] The synchronizing rod 310 is sleeved on the rotating shaft 434, and the synchronizing rod 310 is rotatably mounted on the locking seat 431.

[0032] Specifically, when the user presses the unlock button 410, the unlock button 410 rotates relative to the unlock mounting base 101. This rotation pushes the unlock lever 420, causing it to move towards the unlock button 410. The movement of the unlock lever 420 causes the pawl plate 433 to rotate relative to the locking seat 431, disengaging the pawl plate 433 from the ratchet 432. At this time, the angle limiting plate 436 limits the pawl plate 433. The two retractors 300 are connected to the rotating shaft 434 via the synchronizing rod 310. When the ratchet 432 on the plate 433 separates from the pivot rod 434, the ratchet 432 is unrestricted, and the two retractors 300 can rotate under the action of their own coil springs, driving the synchronizing rod 310 to rotate. The ratchet 432 rotates with the synchronizing rod 310, and the two retractors 300 can unwind the two adjusting webbing 230, thereby increasing the length of the two adjusting webbing 230 outside the retractors 300. At this time, the user can pull down the berth body 100, so that the berth body 100 can be moved from the vertical storage state to the horizontal use state.

[0033] Furthermore, when the user releases the unlock button 410, the unlock button 410 is reset under the action of the first reset spring 411, and the pawl plate 433 is reset under the action of the second reset spring 435, so that the pawl plate 433 engages with the ratchet 432, so that the ratchet 432 cannot rotate, thereby locking the two retractors 300, so that the two adjusting webbing 230 cannot continue to be stretched outward. The user can flip the horizontal berth body 100 to the vertical storage state. At this time, the berth body 100 no longer presses the adjusting webbing 230, so that the retractor 300 can wind up the adjusting webbing 230 under its own elasticity.

[0034] In addition, the unlocking lever 420 is reset under the action of the third reset spring 437.

[0035] See Figures 1-17 As shown, in the optional embodiment, the protective net assembly 200 includes a protective net 210, a support rod 220, and two adjusting webbing straps 230. One end of the adjusting webbing strap 230 is connected to the retractor 300 via the bottom of the berth body 100, and the other end is provided with a locking piece 231. The locking piece 231 is detachably connected to a roof bracket 232, which is mounted on the vehicle body. Both ends of the support rod 220 have through-channels, the axis of which is perpendicular to the axis of the support rod 220. Both adjusting webbing straps 230 pass through the through-channels to allow the support rod 220 to move on the adjusting webbing straps 230. An elastic rope 221 is threaded through the support rod 220, and both ends of the elastic rope 221 are connected to the two adjusting webbing straps 230 respectively. One end of the protective net 210 is mounted on the support rod 220, and the other end is connected to the berth body 100.

[0036] The protective net 210 has multiple energy-absorbing webbing 240 at the end away from the support rod 220, and the end of the energy-absorbing webbing 240 away from the protective net 210 is attached to the berth body 100; the middle part of the energy-absorbing webbing 240 is folded and connected together by weakened stitching 241; the end of the protective net 210 away from the support rod 220 is provided with a support plate 250, and the support plate 250 is connected to the berth body 100.

[0037] Specifically, one end of the protective net 210 is fitted onto the support rod 220, and both ends of the support rod 220 are respectively threaded onto two adjusting webbing 230, so that the support rod 220 can move up and down along the adjusting webbing 230. An elastic rope 221 is threaded inside the support rod 220, and both ends of the elastic rope 221 are respectively connected to two locking plates 231. When the user pulls down the protective net 210 to place items or perform other operations and then releases the protective net 210, the protective net 210 automatically resets under the action of the elastic rope 221.

[0038] Additionally, a roof mounting bracket 232 is provided on the inner side wall of the vehicle, and a locking plate 231 is engaged in the roof mounting bracket 232. A trigger button is provided on the roof mounting bracket 232, which can unlock the locking plate 231.

[0039] Supporting this is the fact that multiple energy-absorbing webbing strips 240 are installed on the protective net 210. The end of the energy-absorbing webbing strip 240 away from the protective net 210 is fixed to the roller beam frame 110 of the sleeper body 100. A support plate 250 is inserted through the bottom of the protective net 210 and is fixed to the roller beam frame 110 of the sleeper body 100. The middle part of the energy-absorbing webbing strip 240 is folded and connected together by weakening seams 241. With this arrangement, in the event of a collision, the weakening seams 241 break instantly, and the folded part of the energy-absorbing webbing strip 240 straightens, providing the energy absorption function of the protective net 210. This prevents the collision energy from concentrating in other sewn areas and causing other parts to break, effectively preventing passengers or luggage from falling during a collision.

[0040] See Figures 1-17 As shown, in the optional embodiment, the sleeper body 100 includes a roller beam frame 110 and a plastic honeycomb panel 120; multiple reinforcing plates 130 are provided on the roller beam frame 110, and the plastic honeycomb panel 120 is provided on the reinforcing plates 130; a foamed surface cover 140 is provided on the roller beam frame 110.

[0041] Specifically, the main body of the roll-formed beam frame 110 is made of 0.6mm thin plate roll-formed parts. The roll-formed beam frame 110 and the reinforcing plate 130 are riveted together. The bottom surface of the roll-formed beam frame 110 is filled with plastic honeycomb board 120. The overall assembly process is simple and the weight is light. The closed cavity of the roll-formed beam frame 110 is not easy to deform or tear after roll forming.

[0042] In addition, galvanized sheet can be used for roll forming parts, or a face sleeve can be used inside the roll forming cavity to avoid the use of painting or electrophoresis treatment. The surface treatment cost is low and it is environmentally friendly.

[0043] See Figures 1-17 As shown, in the optional embodiment, the roller beam frame 110 is provided with a hinge mounting bracket 150, the hinge mounting bracket 150 is provided with a guide groove 151 inside, the guide groove 151 is an isosceles trapezoid, and the hinge mounting bracket 150 is provided with a pivot hole 152 at the end of the guide groove 151; it also includes a hinge fixing bracket 500, the hinge fixing bracket 500 is provided with a rotating shaft 510, and the rotating shaft 510 is pivotally connected in the pivot hole 152.

[0044] Specifically, the hinge fixing bracket 500 and the hinge hook bracket 150 are engaged. First, the hinge fixing bracket 500 is fixed to the vehicle body, and the hinge hook bracket 150 is installed on the sleeper body 100. When installing the sleeper body 100, simply hook the hinge hook bracket 150 on the sleeper body 100 onto the hinge fixing bracket 500 to complete the assembly. The operation is convenient and easy to disassemble and replace.

[0045] During the connection process, the hinge fixing bracket 500 has a rotating shaft 510, and a pivot hole 152 is provided at the end of the guide slide 151. The rotating shaft 510 slides into the isosceles trapezoidal guide slide 151. The rotating shaft 510 can open the outer wall of the guide slide 151, so that both ends of the rotating shaft 510 enter the pivot hole 152, completing the connection between the hinge fixing bracket 500 and the hinge connection bracket 150. The hinge fixing bracket 500 and the hinge connection bracket 150 can rotate relative to each other, so that the user can fold the horizontal berth body 100 into a vertical position.

[0046] When the rotating shaft 510 is engaged in the guide groove 151 of the hinge mounting bracket 150, as the rotating shaft 510 moves toward the pivot hole 152, the rotating shaft 510 can open the side wall of the guide groove 151 and then enter the pivot hole 152. The side wall of the guide groove 151 will return to its original position under its own elasticity.

[0047] It should be noted that the hinge mounting bracket 150 includes a metal base 153, a plastic inner shell 154, and a plastic outer shell 155. The metal base 153 is fixed on the roller beam frame 110, the plastic inner shell 154 is disposed inside the metal base 153, and the plastic outer shell 155 is disposed outside the metal base 153.

[0048] See Figures 1-17 As shown, in an optional embodiment, a spring mattress 160 is provided on the plastic honeycomb panel 120, and the spring mattress 160 is filled with sponge.

[0049] Specifically, the 160 spring mattress has fewer volatile organic compounds, good overall resilience and breathability, providing occupants with a good comfort experience. At the same time, the 160 spring mattress has good pressure resistance and temperature change resistance, which can effectively extend the service life of the sleeping berth assembly.

[0050] In addition, the spring mattress 160 is filled with foam to improve comfort.

[0051] This embodiment provides a commercial vehicle, including a pull-rod unlocking upper sleeper berth.
