Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of supporting equipment for a truck cab, in particular to an upper berth assembly. The utility model also relates to a truck using the upper berth assembly. Background Art
[0002] In the current commercial vehicle manufacturing field, sleeping berth facilities are usually arranged in the vehicle cab to meet the rest and living needs of the driver and passengers during long-distance freight or passenger travel.
[0003] Especially in truck cabs, a berth is usually arranged behind the conventional main driving seat so that the truck driver can take a nap and rest on the berth when he is tired, or when it is inconvenient to find a suitable accommodation, the driver and passengers can sleep and rest on the berth, thus ensuring the on-board living needs of commercial vehicle drivers and passengers.
[0004] In the current conventional truck cab supporting equipment structure layout, two berths are usually arranged in an upper and lower position, and the arrangement structure of the two berths is similar to the upper and lower berths arranged on the same side of the sleeper compartment of a passenger train, so as to meet the living and rest needs of two drivers or passengers. Usually, the two berths in the truck cab are integral berth structures, and the upper and lower berths are respectively fixed on the rear inner wall of the truck cab.
[0005] Accordingly, taking into account the convenience and ease of use in actual vehicle life, the industry currently usually tilts and lifts the outer side of the upper berth appropriately to make the upper berth form an inclined structure with a higher outer edge and a lower inner edge, thereby increasing the distance between the outer edges of the two berths, thereby increasing the head space for the driver and passengers, and allowing the driver and passengers to move more freely and comfortably on the lower berth when they are not sleeping in the truck cab, thereby avoiding the upper berth hitting the driver and passengers' heads.
[0006] However, although the above-mentioned overall tilting and flipping action mode can meet the current truck driver and passenger's living needs, due to the height limitation of the internal space of the truck cab, the existing technology can usually only flip the upper berth upward at a small angle as a whole, so as to prevent the upper berth from flipping upward at an excessively large angle and colliding or getting stuck with the cab ceiling. This results in the existing upper berth having a very limited flipping and tilting angle, and the correspondingly increased head space and activity space for the driver and passengers are also very cramped, resulting in the driver and passengers still feeling depressed when sitting on the lower berth, and after the upper berth is flipped upward, the space between the top surface of the upper berth and the top surface and rear inner wall of the truck cab cannot be utilized, resulting in a waste of truck cab space, reducing space utilization and the living comfort of the driver and passengers.
[0007] In view of this, how to optimize the berth structure in the truck cab to avoid the adverse effects of the berth structure located above on the driver and passengers' life on the truck, and optimize the head space of the driver and passengers in the truck cab are important technical issues that technical personnel in this field currently need to solve.

[0038] Please refer to Figures 1 to 4 .
[0039] In a specific embodiment, the upper berth assembly provided by the utility model includes an inner bed body 11 and an outer bed body 12 which are arranged horizontally, and the inner bed body 11 and the outer bed body 12 are parallel to each other in length direction and are closely arranged in width direction.
[0040] The inner edge of the inner bed 11 is fixed to the inner wall of the side of the cab, and the outer edge of the inner bed 11 is hinged to the inner edge of the outer bed 12 through a folding hinge 13. The extension direction of the hinge axis of the folding hinge 13 is parallel to the length direction of the inner bed 11, and the outer bed 12 can be rotated upward around the hinge axis of the folding hinge 13 and flipped up.
[0041] In addition, the upper berth assembly also includes a position limiting support component that cooperates with the outer bed body 12.
[0042] During operation, when the driver and passengers need to sleep, the outer bed body 12 and the inner bed body 11 can be unfolded horizontally and arranged in parallel, so that the top surface of the inner bed body 11 is flush with the top surface of the outer bed body 12, thereby forming a relatively wide load-bearing surface for the driver and passengers to lie on the load-bearing surface to ensure sleeping comfort; when the driver and passengers have no need to sleep, or do not need to use the upper berth assembly as a lying space, the outer bed body 12 can be flipped up around the hinge axis of the folding hinge 13 by using the folding hinge 13 until the original position of the outer bed body 12 when it is unfolded is completely The upper and lower berths are completely out of the way so that when the driver and passengers sit on the lower berth assembly below the upper berth assembly, or when they pass by or stand on the outside of the upper berth assembly, the driver and passengers' heads will not be blocked or obstructed by the outer bed body 12, effectively avoiding the interference of the outer bed body 12 on the driver and passengers' head space, making the longitudinal space inside the truck cab more ample, thereby greatly optimizing the driver and passengers' head space in the truck cab, avoiding the horizontal extension structure of the outer bed body 12 of the upper berth assembly from causing adverse effects on the driver and passengers' life on the truck, and making the driver and passengers' life in the truck cab more convenient and comfortable.
[0043] Generally, considering the daily use comfort of the upper berth assembly, soft cushions 10 can also be laid on the top of the outer bed body 12 and the inner bed body 11 to optimize the touch feeling of the driver and passengers lying on the upper berth assembly, making the driver and passengers more comfortable and relaxed when resting and sleeping on the upper berth assembly.
[0044] When the components are assembled, the cushion 10 and the main structure of the outer bed body 12 and the inner bed body 11 can be fixed to the corresponding top corners of the outer bed body 12 and the inner bed body 11 by means of the rings arranged at the top corners of the cushion 10, so as to complete the reliable assembly and flexible disassembly between the cushion 10 and the outer bed body 12 and the inner bed body 11; or the cushion 10 can be realized by means of the connecting components arranged in pairs and capable of being disassembled and adapted, such as buckles or nylon buckles, so as to ensure the connection strength between the cushion 10 and the outer bed body 12 and the inner bed body 11, and to remove the cushion 10 from the inner bed body 11 and the outer bed body 12 when necessary, so as to clean and replace the cushion 10, and keep the contact part of the upper berth assembly with the driver and passengers clean and hygienic.
[0045] In actual applications, the soft cushion 10 can be a sponge pad, a rubber pad or other flexible materials with a soft texture and good cushioning effect. The staff can flexibly select the specific material of the soft cushion 10 based on the actual working conditions and combined with factors such as the cost of use. In principle, as long as it can meet the actual application needs of the upper berth assembly, it can be selected.
[0046] Specifically, the limit support assembly includes a suspension support device that is detachably connected between the outer edge of the outer bed 12 and the top inner wall of the cab, and also includes a limit device connected between the outer bed 12 and the inner bed 11. In actual operation, the limit device can provide reliable structural limit for the outer bed 12 in a horizontal extension state or in an upward folded state, to prevent the outer bed 12 from being structurally loose or misaligned when it is horizontally extended and flush with the inner bed 11 or when it is flipped up, thereby ensuring the structural stability and operational safety of the outer bed 12. When the outer bed 12 is flipped up around the hinge axis of the folding hinge 13, the outer bed 12 can be reliably suspended and connected to the bottom of the top inner wall of the cab by using the suspension support device, thereby providing reliable structural support and a stable fulcrum for the outer edge of the outer bed 12, thereby further improving the structural stability and safety of the outer bed 12 when it is in the flipped-up state.
[0047] More specifically, the suspension support device includes a protective net 14 that can be extended in the vertical direction, and the main extension surface direction of the protective net 14 is perpendicular to the width direction of the outer bed 12. The top of the protective net 14 is detachably connected to the top inner wall of the cab through a protective belt 141, and the bottom of the protective net 14 is connected to the outer edge of the outer bed 12. The protective net 14 and the protective belt 141 are preferably made of flexible materials with a certain structural elasticity. Considering the safety of use in actual applications, the protective belt 141 and the protective net 14 should be made of flexible materials with high structural strength and good load-bearing capacity, such as nylon braided belts, to prevent the protective belt 141 and the protective net 14 from elastically deforming too much after bearing the load, which may cause people or objects on the outer bed 12 and the inner bed 11 to fall.
[0048] In actual applications, the protective net 14 can provide reliable lateral limitation and structural protection for people on the upper berth assembly or objects placed on the upper berth assembly, so as to prevent people or objects on the outer bed body 12 and the inner bed body 11 from falling from the upper berth assembly, thereby further improving the safety of the upper berth assembly.
[0049] On this basis, a net box 142 capable of accommodating the protective net 14 is provided at the outer edge of the outer bed 12, and a net guide port 143 is provided at the top of the net box 142 for the protective net 14 to enter and exit the net box 142. A reel and a reel-in drive device capable of driving the reel-in to rotate around its own axis are provided in the net box 142, and the axis of the reel-in extends along the length direction of the outer bed 12. When the protective net 14 is not needed, the top of the protective belt 141 can be removed from the inner wall of the cab top to release the top fixation and limit of the protective net 14 and the protective belt 141. At this time, the reel-in drive device can drive the reel-in to rotate in the forward direction, so that the protective net 14 is continuously wound around the reel-in until the main structure of the protective net 14 is received into the inner cavity of the net box 142 through the net guide port 143 and tightly wound around the reel-in, thereby completing the reeling of the protective net 14. As a result, when the upper berth assembly is in an unconventional use state, the main structure of the protective net 14 can be reliably rolled up and stored, avoiding the main structure of the protective net 14 extending and interfering with the surrounding space of the upper berth assembly in the non-use state, thereby avoiding the protective net 14 from encroaching on the internal space of the cab when not in use, thereby further optimizing the head space of the driver and passengers and improving the comfort of the driver and passengers in the vehicle.
[0050] When the protective net 14 needs to be unfolded again, the reel-in drive device can be used to drive the reel-in shaft to reverse, so as to drive the protective net 14 to be continuously discharged and stretched through the net guide port 143 until the outward extension structure of the protective net 14 is sufficient to allow the top of the protective belt 141 to be reliably connected to the inner wall of the cab top.
[0051] It should be noted that the top of the protective belt 141 and the inner wall of the cab top can be connected by a buckle and a tongue adapter mechanism or a hook and a hanging hole adapter mechanism to achieve flexible disassembly and reliable suspension connection. Of course, other connection mechanisms that can stably align and connect and facilitate disassembly and assembly operations can also be selected as the specific connection mechanism between the protective belt 141 and the inner wall of the cab top. In principle, any connection mechanism that can meet the actual operation and use requirements of the upper berth assembly can be used.
[0052] Furthermore, a limit end rod 144 is provided at the top edge of the protective net 14, the axis of the limit end rod 144 extends along the length direction of the outer bed body 12, and the outer diameter of the limit end rod 144 is greater than the width of the net guide port 143 along the width direction of the outer bed body 12. When the protective net 14 is wound up, the limit end rod 144 can be reliably connected to the outer side of the net guide port 143, so as to prevent the entire structure of the protective net 14 from being put into the net collection box 142, thereby increasing the difficulty of operation when the protective net 14 is re-extended. When the protective net 14 gathered in the net collection box 142 needs to be re-extracted and extended, the protective belt 141 can be used to drive the limit end rod 144 to move upward, thereby smoothly extracting the protective net 14 in the net collection box 142 and extending it upward and outward, which greatly reduces the difficulty of operation when the protective net 14 is unrolled, improves the efficiency and movement accuracy of the unrolling operation of the protective net 14, and makes the unwinding operation of the protective net 14 smoother and more convenient.
[0053] On this basis, the reeling and unreeling drive device is a torsion spring. The torsion spring has a simple structure and high action efficiency, which can effectively ensure the efficiency of the reeling action of the protection net 14. The torsion spring and the above-mentioned limit end rod 144 have a good cooperation effect, so that the staff can hold and pull the protection belt 141, drive the limit end rod 144 to move up along with the protection belt 141, thereby driving the protection net 14 to achieve the unreeling operation.
[0054] It is not difficult to understand that in actual applications, the bottom end of the protective belt 141 can be directly connected to the limit end rod 144 by means of a sleeve, and the top end of the protective net 14 can also be reliably connected to the limit end rod 144 in the form of a sleeve, thereby achieving a reliable linkage connection between the protective belt 141, the limit end rod 144 and the protective net 14, fully ensuring the efficiency and operation accuracy of the winding and unwinding action of the protective net 14, and making the operation of the upper berth assembly more convenient and efficient.
[0055] It should be noted that, considering the layout requirements under normal working conditions, the outer bed 12 and the inner bed 11 are arranged behind the driver's seat along the length direction of the truck cab, and the length direction of the outer bed 12 and the inner bed 11 is consistent with the width direction of the truck cab, while the width direction of the outer bed 12 and the inner bed 11 is consistent with the length direction of the cab. Note that the length direction of the truck cab mentioned here is also the driving direction of the truck. Unless otherwise specified in the rest of this article, it can be understood by referring to the corresponding here and will not be repeated.
[0056] On the other hand, the limiting device is a gas spring 15, which is arranged at the same end of the inner bed body 11 and the outer bed body 12 along the length direction of the inner bed body 11 and the outer bed body 12, and the extension direction of the gas spring 15 is perpendicular to the extension direction of the hinge axis of the folding hinge 13. One end of the gas spring 15 is connected to the end of the inner bed body 11, and the other end of the gas spring 15 is connected to the end of the outer bed body 12. When the inner bed body 11 and the outer bed body 12 are extended in parallel so that the top surfaces of the two are flush, the gas spring 15 is in a horizontally extended state. At this time, the two ends of the gas spring 15 are respectively reliably connected to the sides of the outer bed body 12 and the inner bed body 11, so as to utilize the extension structure of the gas spring 15 itself to realize reliable limitation of the outer bed body 12 and the inner bed body 11, and avoid accidental folding or misalignment of the outer bed body 12 relative to the inner bed body 11; when the outer bed body 12 is folded upward relative to the inner bed body 11, the gas spring 15 can be synchronously and appropriately contracted along with the upward turning action of the outer bed body 12 until the extended length of the gas spring 15 matches the flipping structure of the outer bed body 12. At this time, the two ends of the gas spring 15 are still reliably connected to the sides of the outer bed body 12 and the inner bed body 11, so as to realize reliable limitation of the current folding state of the outer bed body 12 through the inclined extension structure of the gas spring 15 itself, and avoid the outer bed body 12 from loosening or misalignment from the current folding position.
[0057] Therefore, the gas spring 15 is used to fully ensure the reliable locking and limiting of the relative position and matching state between the outer bed body 12 and the inner bed body 11, so that the operational safety and convenience of use of the upper berth assembly are further improved.
[0058] Of course, in actual applications, the limiting device can also be a strut, and anchor holes that can be hinged to the ends of the strut are respectively provided on the inner bed body 11 and the outer bed body 12, serving as anchor points for the two ends of the strut to be respectively connected to the inner bed body 11 and the outer bed body 12, so that when the outer bed body 12 is flipped over or extended flat relative to the inner bed body 11, the ends of the struts can be hinged to the corresponding anchor holes to achieve locking and limiting of the current matching positions of the outer bed body 12 and the inner bed body 11, thereby ensuring the structural reliability and safety of the upper berth assembly.
[0059] It should be noted that the outer bed 12 rotates upward around the hinge axis of the folding hinge 13 by not less than 90°, so that the outer bed 12 after folding upward can provide the most ample head space for the driver and passengers, thereby further improving the comfort of the driver and passengers.
[0060] In addition, the upper berth assembly also includes a fixing seat 16 fixed on the inner wall of the side of the cab, and the inner edge of the inner bed body 11 is hinged to the fixing seat 16 through a folding hinge 161. The extension direction of the hinge axis of the folding hinge 161 is parallel to the extension direction of the hinge axis of the folding hinge 13, and the inner bed body 11 can be turned up or rotated down around the hinge axis of the folding hinge 161. If necessary, the inner bed body 11 can be controlled to turn up around the hinge axis of the folding hinge 161, so that both the outer bed body 12 and the inner bed body 11 are folded to a state where they are in contact with or parallel to the inner wall of the side of the cab. In this way, the upper berth assembly can be folded as a whole to a position close to the side wall of the cab, thereby almost completely releasing the assembly space occupied by the upper berth assembly in the horizontally extended state, thereby allowing the driver and passengers in the lower berth assembly to obtain the most ample head room, effectively avoiding the interference and blocking of the driver and passengers' head space by the upper berth assembly, making the driver and passengers' life in the truck cab more comfortable and making the use of the upper berth assembly more convenient and flexible.
[0061] In actual operation, the outer bed body 12 and the inner bed body 11 can be folded into place as a whole around the folding hinge 161 when the top surfaces are flush with each other. Alternatively, the outer bed body 12 can be folded around the folding hinge 13 to a snap-fitting state in contact with the top surface of the inner bed body 11, and then the outer bed body 12 and the inner bed body 11 in the snap-fitting state can be folded down or upward together around the folding hinge 161, thereby achieving flexible adaptation of the folding and folding structure of the upper berth assembly to meet the differentiated adaptation requirements of the assembly space under different working conditions, thereby improving the working condition adaptability and ease of use of the upper berth assembly.
[0062] In a specific embodiment, the truck provided by the utility model includes a vehicle body and a cab located on the vehicle body, wherein the cab is provided with an upper berth assembly and a lower berth assembly arranged in sequence from top to bottom in a vertical direction, wherein the upper berth assembly is the upper berth assembly described above. The upper berth assembly of the truck will not interfere with the head space of the driver and passenger, thereby optimizing the head space of the driver and passenger in the truck cab and avoiding the adverse effect of the component structure of the upper berth assembly on the driver and passenger's life on the truck.
[0063] In summary, it can be seen that during the operation and use of the upper berth assembly provided in the utility model, when it is needed for the driver and passengers to sleep, the outer bed body and the inner bed body can be unfolded in the horizontal direction and arranged in parallel, so that the top surface of the inner bed body is flush with the top surface of the outer bed body, thereby forming a relatively wide load-bearing surface, so that the driver and passengers can lie on the load-bearing surface to ensure the comfort of sleeping; when the driver and passengers have no need to sleep, or do not need to use the upper berth assembly as a lying space, the outer bed body can be flipped up around the hinge axis of the folding hinge by using the folding hinge until the original outer bed body is unfolded. The position is completely cleared so that when the driver and passengers sit on the lower berth assembly below the upper berth assembly, or pass by or stand on the outside of the upper berth assembly, the heads of the driver and passengers will not be blocked or obstructed by the outer bed body, effectively avoiding the interference of the outer bed body with the head space of the driver and passengers, making the longitudinal space inside the truck cab more ample, thereby greatly optimizing the head space of the driver and passengers in the truck cab, avoiding the horizontal extension structure of the outer bed body of the upper berth assembly to cause adverse effects on the life of the driver and passengers, and making the life of the driver and passengers in the truck cab more convenient and comfortable.
[0064] The utility model also provides a truck, whose upper berth assembly will not interfere with the head space of the driver and passenger, thereby optimizing the head space of the driver and passenger in the truck cab and avoiding the adverse effect of the component structure of the upper berth assembly on the driver and passenger's life on the truck.
