Description

Technical Field

[0001] This invention belongs to the field of truck sleeper technology, specifically relating to an electric, non-marking, widened truck sleeper. Background Technology

[0002] Heavy trucks are mostly used for long-distance transportation. Drivers are prone to fatigue after driving for a long time. To facilitate drivers' rest, a sleeper berth is designed in the cab. The sleeper berth is located behind the driver's seat and is fixed to the side wall of the cab. In addition, the existing sleeper berths on heavy trucks have been widened to improve the comfort of drivers when resting.

[0003] Patent publication number CN221250820U discloses a guardrail for a truck sleeper berth, the truck sleeper berth, and the truck itself. The guardrail is installed on the edge of the sleeper berth body and includes: a guardrail body with an operating surface, the operating surface being equipped with a display screen and buttons; and at least one movable arm movably connected between the guardrail body and the mounting groove of the sleeper berth body. The movable arm can move the guardrail body to switch between a protective position and a concealed position. In the protective position, the guardrail extends above the sleeper berth body; in the concealed position, the guardrail is hidden within the mounting groove. This patented guardrail design is flexible, providing protection without hindering passenger movement, and its intelligent design helps improve the passenger's quality of life.

[0004] The aforementioned device also has the following problems: While the device's flexibly designed guardrails do not hinder passenger movement, the foam pad used for sleeping is difficult to extend seamlessly and automatically when the driver is resting, which reduces the driver's lying area and thus reduces the quality of rest due to limited space. Furthermore, it is difficult to ensure the foam pad remains dry during prolonged use, making it prone to bacterial growth due to moisture. Additionally, when users roll over, it is difficult to evenly distribute the weight on one side, increasing wear and tear on the base frame and mounting points. Summary of the Invention

[0005] The purpose of this invention is to provide an electrically operated, seamless, and expandable truck sleeper berth to solve the problem mentioned in the background art that when the driver rests, the foam pad used for sleeping is difficult to expand seamlessly and automatically, which to some extent reduces the lying area of ​​the driver when resting, and thus easily reduces the quality of rest due to the limited area.

[0006] To achieve the above objectives, this invention provides an electric, non-marking, widened truck sleeper berth, comprising: a base frame, with two support frames symmetrically and fixedly installed at the bottom left end of the base frame; a limit block fixedly installed at the top of the support frame; a fixed frame fixedly installed through the outer wall of the limit block; a movable frame movably installed through the fixed frame; the movable frame has a hollow design in its middle section; an anti-mildew device to ensure the dryness of the sponge pad inside the movable frame is provided inside the movable frame; an anti-slip device to achieve gravity balance is provided to the left of the anti-mildew device; the bottom of the movable frame contacts the top of the fixed frame, and the movable frame is flush with the top of the fixed frame; a sponge pad is fixedly installed at the top of the movable frame; the bottom left end of the sponge pad is fixedly installed at the top of the fixed frame; the base frame is rotatably mounted on the side wall inside the cab; when resting, the base frame is rotated 90 degrees, after which the drive mechanism inside the fixed frame is activated; the drive mechanism can be voice-controlled, and the drive mechanism will cause the movable frame to slide horizontally and extend along the inside of the fixed frame. When the moving frame moves, it pushes the sponge pad to stretch, at which point the knife marks on its surface are stretched into holes, thus achieving a seamless expansion of the sponge pad. An L-shaped plate is slidably installed inside the right end of the base frame, and a T-shaped circular plate is fixedly installed at the bottom of the middle end of the moving frame. The moving frame pulls the L-shaped plate and the T-shaped circular plate to move synchronously. The L-shaped plate extends outward along the inside of the base frame, and the T-shaped circular plate slides along the limiting groove of the support frame. Thus, when the driver rests on the sponge pad, gravity causes the moving frame to generate a downward force. A toothed plate is fixedly installed through the outer wall of the moving frame. A rotating roller is rotatably installed on the top left end of the toothed plate. A guide plate is fixedly installed at the inner edge of the sponge pad. The moving frame drives the toothed plate to move horizontally, and the toothed plate drives the rotating roller to move synchronously. The circumferential surface of the roller contacts and abuts the arc surface of the guide plate. At this time, the guide plate generates a force, and the guide plate pushes the inner edge of the sponge pad. At this time, the edge of the sponge pad begins to extend, and the sponge pad fills the gap between itself and the inner side wall of the driver's cab.

[0007] In the above technical solution, the left end of the base frame is rotatably mounted on the side wall of the cab, and the base frame has a U-shaped design. The bottom end of the support frame has a limiting groove. A retractor is provided on the outside of the fixed frame. At the same time, a bed sheet is rolled up on the surface of the retractor on the outside of the fixed frame. When the sponge pad expands, the bed sheet is pulled by the sponge pad to cover it without leaving a trace. Then, it is reset by the retractor. The bottom of the fixed frame is fixedly connected to the top of the base frame. A motor is provided on the inner side wall of the fixed frame. A drive mechanism is provided inside both ends of the fixed frame. The drive mechanism consists of a transmission shaft and a spiral telescopic push rod. The transmission shaft is driven to rotate by the motor, and the spiral telescopic push rod is rotated by a bevel gear to achieve the driving function. The output end of the fixed frame drive mechanism is connected to the side wall of the moving frame.

[0008] In the above technical solution, the surface of the sponge pad is further marked with uniformly distributed and penetrating knife marks, the top right end of the L-shaped plate is fixedly installed at the bottom right end of the movable frame, the bottom end of the T-shaped circular plate moves through the inside of the bearing frame limiting groove, and the top bottom end of the T-shaped circular plate contacts the bottom of the bearing frame, and the arc surface of the guide plate contacts the circumferential surface of the rotating roller.

[0009] In the above technical solution, the anti-mildew device further includes a transmission rod, the outer wall of which is rotatably mounted inside the base frame, a gear is fixedly mounted on one end of the transmission rod near the toothed plate, the gear meshes with the toothed plate, a U-shaped plate is movably mounted on the outer wall of the transmission rod, a vertical rod is fixedly mounted on the top of the fixed frame, a contact plate is slidably mounted on the outer wall of the vertical rod through a spring, and a vent is fixedly mounted on the top of the contact plate.

[0010] In the above technical solution, the outer wall of the transmission rod is provided with a non-self-locking spiral groove. The bottom and top of the U-shaped plate are slidably installed on the top of the base frame. The bottom of the abutment plate contacts the top of the U-shaped plate. When the toothed plate moves horizontally, it causes the meshing gear to start rotating. When the gear rotates, it drives the transmission rod to rotate inside the base frame. When the transmission rod rotates, it guides the built-in locking block of the U-shaped plate through the non-self-locking spiral groove on its outer wall. The U-shaped plate slides horizontally along the bottom of the base frame. The outer wall of the vent cylinder moves through the inside of the sponge pad, and the vent cylinder contains desiccant particles. At this time, the U-shaped plate releases its pushing action on the abutment plate. The abutment plate slides downward along the outer wall of the vertical rod by the spring force. The abutment plate drives the vent cylinder to detach from the inside of the sponge pad. That is, the vent cylinder is inside the sponge pad when it is not in use, and it detaches from the sponge pad when it is in use.

[0011] In the above technical solution, further, an arc frame is fixedly installed on the side of the U-shaped plate away from the toothed plate, and a counterweight is slidably installed inside the hollow of the movable frame by a spring. The arc surface of the end corner of the counterweight is located on the movement trajectory of the arc frame. The U-shaped plate drives the arc frame to move away from the toothed plate, and the arc surface of the arc frame abuts against and pushes the counterweight. At this time, the counterweight slides horizontally in the hollow of the movable frame, thereby changing the position of the counterweight.

[0012] In the above technical solution, the anti-fall device further includes a push frame. The push frame is horizontally slidably installed on the side wall of the support frame away from the gear by a spring. An elastic telescopic plate is rotatably installed on the left side wall of the push frame by a torsion spring. When the U-shaped plate moves horizontally, it contacts and pushes the push frame. When the push frame slides horizontally along the side wall of the support frame, it will drive the elastic telescopic plate to move synchronously. The bottom of the elastic telescopic plate is limited by the crossbar. At this time, the hinge axis of the elastic telescopic plate begins to rotate, that is, the elastic telescopic plate moves in an arc trajectory. A square frame is fixedly installed at the bottom edge of the base frame, and a crossbar is fixedly installed inside the square frame.

[0013] In the above technical solution, further, the right end arc surface of the push frame contacts the surface of the U-shaped plate, the outer wall of the crossbar is penetrated and rotatably installed inside the elastic telescopic plate, the telescopic end of the elastic telescopic plate begins to contract and applies downward pressure to the crossbar, the crossbar is limited by the square frame and remains stationary, at this time the square frame causes the base frame to generate a downward force.

[0014] In the above technical solution, further, an L-shaped frame is fixedly installed on the inner side wall of the push frame, and a sensing mechanism is fixedly installed on the side wall of the L-shaped frame. A sensing roller is rotatably installed inside the bottom end of the L-shaped frame. The circumferential surface of the sensing roller contacts the bottom of the T-shaped circular plate. The sensing roller is connected to the sensing mechanism. The push frame drives the L-shaped frame to move horizontally. The L-shaped frame drives the sensing mechanism and the sensing roller to move synchronously. When the rotating sensing roller moves horizontally, it contacts the bottom of the T-shaped circular plate. When a portion of the area between the two is in a non-contact state, the sensing mechanism promptly issues a warning, prompting the user to promptly check whether the right end of the moving frame has fallen.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: by cooperating with a fixed frame, a movable frame, a sponge pad, an L-shaped plate, a T-shaped circular plate, a toothed plate, a rotating roller, and a guide plate, the movable frame enables the sponge pad to expand horizontally and without leaving marks. This increases the lying area for the driver to rest, thereby expanding the driver's activity space and optimizing the quality of rest. At the same time, the T-shaped circular plate and the L-shaped plate support the weight borne by the movable frame when the driver lies down, ensuring safety and preventing misalignment between the movable frame and the fixed frame, which would affect the subsequent use of the seamless expansion. The guide plate pushes the sponge pad to eliminate the gap between it and the side wall of the vehicle during use, preventing mobile phones or other items from falling and causing economic losses. In addition, if the vehicle has a double-decker sleeper, this increases the risk of injury to the person on the lower level.

[0016] By incorporating an anti-mildew device, a combination of toothed plates, transmission rods, gears, U-shaped plates, vertical rods, contact plates, vents, curved frames, and counterweights, the downward movement of the vents prevents interference with the expansion of the sponge pad, thus avoiding any impact on its seamless extension. Simultaneously, the vents utilize desiccant particles to dry the interior of the sponge pad, preventing the growth of bacteria due to moisture and ensuring a comfortable resting experience. Furthermore, by altering the position of the counterweights, the weight distribution at both ends of the movable frame is made more balanced after displacement, preventing a right-heavy, left-light distribution. This also prevents the left end of the movable frame from deviating from the drive mechanism within the fixed frame, thus reducing the likelihood of the right end of the sponge pad being in a non-horizontal position.

[0017] By incorporating an anti-fall device, a combination of a U-shaped plate, push frame, elastic telescopic plate, square frame, crossbar, L-shaped frame, sensing mechanism, and sensing roller, the downward pressure of the elastic telescopic plate distributes the weight among the base frame, fixed frame, and moving frame. This prevents uneven stress on the overall frame caused by the driver lying on the right side of the moving frame, which could increase connection wear between the base frame and the cab over time and prevent gaps from forming between the base frame connection and the cab due to falling forces. The sensing roller's contact detection can promptly detect whether the moving frame has detached from the drive mechanism of the fixed frame, thus warning users of the potential risk of the moving frame falling if it has been used for a long time without timely maintenance, thereby increasing the safety of the equipment.

[0020] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0021] like Figures 1-9 As shown, one embodiment of the present invention provides: an electric non-marking widened truck sleeper, comprising: a base frame 1, two support frames 2 symmetrically and fixedly installed at the bottom left end of the base frame 1, a limiting block 3 fixedly installed at the top of the support frame 2, a fixed frame 4 fixedly installed through the outer wall of the limiting block 3, a movable frame 5 movably installed through the fixed frame 4, and the movable frame 5 having a hollow design in the middle, and an anti-mildew device 12 for ensuring the dryness of the sponge pad 6 is provided inside the movable frame 5, and a weight-bearing device is provided on the left side of the anti-mildew device 12. The anti-fall device 13 with force balance has the bottom of the movable frame 5 in contact with the top of the fixed frame 4, and the top of the movable frame 5 and the fixed frame 4 are flush. A sponge pad 6 is fixedly installed on the top of the movable frame 5. The bottom left end of the sponge pad 6 is fixedly installed on the top of the fixed frame 4. An L-shaped plate 7 is slidably installed inside the right end of the base frame 1. A T-shaped round plate 8 is fixedly installed at the bottom middle end of the movable frame 5. A toothed plate 9 is fixedly installed through the outer wall of the movable frame 5. A rotating roller 10 is rotatably installed on the top left end of the toothed plate 9. A guide plate 11 is fixedly installed at the inner edge of the sponge pad 6.

[0022] The left end of the base frame 1 is rotatably mounted on the side wall of the cab, and the base frame 1 has a U-shaped design. The bottom end of the support frame 2 has a limit groove. The fixed frame 4 is equipped with a retractor on the outside. The bottom of the fixed frame 4 is fixedly connected to the top of the base frame 1. The inner side wall of the fixed frame 4 is equipped with a motor. Both ends of the fixed frame 4 are equipped with drive mechanisms. The drive mechanism consists of a transmission shaft and a spiral telescopic push rod. The transmission shaft is driven to rotate by the motor, and the spiral telescopic push rod is rotated by a bevel gear to achieve the driving function. The output end of the drive mechanism of the fixed frame 4 is connected to the side wall of the movable frame 5.

[0023] The surface of the sponge pad 6 is marked with evenly distributed and penetrating knife marks. The top right end of the L-shaped plate 7 is fixedly installed at the bottom right end of the movable frame 5. The bottom end of the T-shaped circular plate 8 moves through the inside of the limiting groove of the bearing frame 2, and the top bottom end of the T-shaped circular plate 8 contacts the bottom of the bearing frame 2. The arc surface of the guide plate 11 contacts the circumferential surface of the rotating roller 10.

[0024] The movable frame 5 allows the sponge pad 6 to expand horizontally and seamlessly, increasing the driver's lying area while resting and thus expanding the driver's activity space to optimize rest quality. Simultaneously, the T-shaped circular plate 8 and L-shaped plate 7 support the weight borne by the movable frame 5 when the driver lies down, ensuring safety and preventing misalignment between the movable frame 5 and the fixed frame 4, which could affect subsequent seamless expansion. The guide plate 11 effectively eliminates the gap between the sponge pad 6 and the vehicle's interior sidewalls during use, preventing mobile phones or other items from falling and causing economic losses. Furthermore, if the vehicle has a double-decker sleeper berth, this increases the risk of injury to the person on the lower level.

[0025] In use, the base frame 1 is rotatably mounted on the side wall inside the cab. During rest periods, the base frame 1 is rotated 90 degrees, activating the drive mechanism inside the fixed frame 4. This drive mechanism, which can be voice-controlled, causes the movable frame 5 to slide horizontally and extend along the interior of the fixed frame 4. As the movable frame 5 moves, it pushes the sponge pad 6 to stretch, causing the knife marks on its surface to become perforated, thus achieving a seamless expansion of the sponge pad 6. Simultaneously, a sheet is wound onto the surface of the retractor outside the fixed frame 4. As the sponge pad 6 expands, the sheet is pulled by the sponge pad 6 to seamlessly cover it. Afterwards, the retractor returns the sheet to its original position, and the movable frame 5 pulls L... L-shaped plate 7 and T-shaped circular plate 8 move synchronously. L-shaped plate 7 extends outward along the inside of the base frame 1, and T-shaped circular plate 8 slides along the limiting groove of the support frame 2. Thus, when the driver rests on the sponge pad 6, gravity causes the moving frame 5 to generate a downward force. The moving frame 5 drives the toothed plate 9 to move horizontally, and the toothed plate 9 drives the rotating roller 10 to move synchronously. The circumferential surface of the roller 10 contacts and abuts the arc surface of the guide plate 11. At this time, the guide plate 11 generates a force of movement and pushes the inner edge of the sponge pad 6. At this time, the edge of the sponge pad 6 begins to extend, and the sponge pad 6 fills the gap between itself and the inner side wall of the driver's cab.

[0026] According to the above embodiments, the movable frame 5 enables the sponge pad 6 to expand horizontally and seamlessly, increasing the lying area for the driver to rest and thus expanding the driver's activity space to optimize rest quality. At the same time, the T-shaped circular plate 8 and L-shaped plate 7 support the weight borne by the movable frame 5 when the driver lies down, ensuring safety and preventing the movable frame 5 from deviating from the fixed frame 4, which would affect the subsequent seamless expansion. The guide plate 11 pushes the sponge pad 6 to eliminate the gap between it and the side wall of the vehicle during use, preventing mobile phones or other items from falling and causing economic losses. If the vehicle has a double-decker sleeper, this increases the risk of injury to the person on the lower level.

[0027] like Figures 1-9 As shown, the second embodiment of the present invention provides: an anti-mildew device 12; The anti-mildew device 12 includes a transmission rod 121, which is rotatably mounted inside the base frame 1 through the outer wall of the transmission rod 121. A gear 122 is fixedly mounted on one end of the transmission rod 121 near the toothed plate 9. The gear 122 meshes with the toothed plate 9. A U-shaped plate 123 is movably mounted through the outer wall of the transmission rod 121. A vertical rod 124 is fixedly mounted on the top of the fixed frame 4. A contact plate 125 is slidably mounted through the outer wall of the vertical rod 124 by a spring. A ventilator 126 is fixedly mounted on the top of the contact plate 125.

[0028] The outer wall of the transmission rod 121 is provided with a non-self-locking spiral groove. The bottom and top of the U-shaped plate 123 are slidably installed on the top of the base frame 1. The bottom of the contact plate 125 contacts the top of the U-shaped plate 123. The outer wall of the vent 126 moves through the inside of the sponge pad 6, and the vent 126 contains desiccant particles.

[0029] A curved frame 127 is fixedly installed on the side of the U-shaped plate 123 away from the toothed plate 9. A counterweight 128 is slidably installed inside the hollowed-out frame 5 via a spring. The curved surface of the end corner of the counterweight 128 is located on the movement trajectory of the curved frame 127.

[0030] By moving the vent 126 downward, interference with the expansion of the sponge pad 6 is avoided, thus preventing it from affecting the seamless extension. At the same time, the vent 126 uses desiccant particles to dry the inside of the sponge pad 6, preventing bacteria from growing inside the sponge pad 6 due to moisture, which could have an adverse effect on the resting personnel. By changing the position of the counterweight 128, the weight of both ends of the movable frame 5 after displacement is made more balanced, avoiding the phenomenon of right-heavy and left-light, thereby preventing the left end of the movable frame 5 from deviating from the drive mechanism inside the fixed frame 4 and increasing the possibility that the right end of the sponge pad 6 is in a non-horizontal position.

[0031] When in use, the horizontal movement of the toothed plate 9 causes the meshing gear 122 to start rotating. When the gear 122 rotates, it drives the transmission rod 121 to rotate inside the base frame 1. When the transmission rod 121 rotates, it guides the internal locking block of the U-shaped plate 123 through the non-self-locking spiral groove on its outer wall. The U-shaped plate 123 slides horizontally along the bottom of the base frame 1. At this time, the U-shaped plate 123 releases its pushing action on the abutment plate 125. The abutment plate 125 slides downward along the outer wall of the vertical rod 124 by the spring force. The abutment plate 125 drives the vent 126 to disengage from the sponge pad 6. That is, the vent 126 is inside the sponge pad 6 when it is not in use, and it is disengaged when in use. The U-shaped plate 123 drives the arc frame 127 to move away from the toothed plate 9. The arc surface of the arc frame 127 abuts against and pushes the counterweight 128. At this time, the counterweight 128 slides horizontally in the hollow part inside the moving frame 5, thereby changing the position of the counterweight 128.

[0032] According to the above embodiment, by moving the ventilation cylinder 126 downward, interference with the expansion of the sponge pad 6 is avoided, thus affecting the seamless extension. At the same time, the ventilation cylinder 126 uses desiccant particles to dry the inside of the sponge pad 6, preventing bacteria from growing inside the sponge pad 6 due to moisture, which would have an adverse effect on the resting personnel. By changing the position of the counterweight block 128, the weight of both ends of the movable frame 5 after displacement is made more balanced, avoiding the phenomenon of right-heavy and left-light, thereby preventing the left end of the movable frame 5 from deviating from the drive mechanism inside the fixed frame 4, and increasing the possibility that the right end of the sponge pad 6 is in a non-horizontal position.

[0033] like Figures 1-9As shown, the third embodiment of the present invention provides: an anti-fall device 13; The anti-fall device 13 includes a push frame 131. The side of the push frame 131 away from the gear 122 is horizontally slidably installed on the side wall of the support frame 2 by a spring. An elastic telescopic plate 132 is rotatably installed on the left side wall of the push frame 131 by a torsion spring. A square frame 133 is fixedly installed at the bottom edge of the base frame 1. A crossbar 134 is fixedly installed inside the square frame 133.

[0034] The right end arc surface of the push frame 131 contacts the surface of the U-shaped plate 123, and the outer wall of the crossbar 134 passes through and is rotatably installed inside the elastic telescopic plate 132.

[0035] An L-shaped frame 135 is fixedly installed on the inner side wall of the push frame 131. A sensing mechanism 136 is fixedly installed on the side wall of the L-shaped frame 135. A sensing roller 137 is rotatably installed inside the bottom end of the L-shaped frame 135. The circumferential surface of the sensing roller 137 contacts the bottom of the T-shaped circular plate 8. The sensing roller 137 is connected to the sensing mechanism 136.

[0036] By pressing down on the elastic telescopic plate 132, the weight distribution among the base frame 1, fixed frame 4, and mobile frame 5 is achieved, preventing uneven stress on the overall frame caused by the driver lying on the right side of the mobile frame 5. This would increase the connection loss between the base frame 1 and the cab over time and prevent the connection end of the base frame 1 from hollowing out due to the force of the fall. Through the contact detection of the sensing roller 137, it is possible to know in time whether the mobile frame 5 has detached from the drive mechanism of the fixed frame 4. In the event of long-term use without timely maintenance, it can warn the user that the mobile frame 5 may fall, thereby increasing the safety of the equipment.

[0037] In use, when the U-shaped plate 123 moves horizontally, it contacts and pushes the push frame 131. When the push frame 131 slides horizontally along the side wall of the support frame 2, it will drive the elastic telescopic plate 132 to move synchronously. The bottom of the elastic telescopic plate 132 is limited by the crossbar 134. At this time, the hinge shaft of the elastic telescopic plate 132 begins to rotate, that is, the elastic telescopic plate 132 moves in an arc trajectory. The telescopic end of the elastic telescopic plate 132 begins to retract and applies downward pressure to the crossbar 134. The crossbar 134 is limited by the square frame 133 and remains stationary. At this time, the square frame 133 causes the base frame 1 to generate a downward force. The push frame 131 drives the L-shaped frame 135 to move horizontally. The L-shaped frame 135 drives the sensing mechanism 136 and the sensing roller 137 to move synchronously. When the rotating sensing roller 137 moves horizontally, it contacts the bottom of the T-shaped circular plate 8. When the area between the two is in a non-contact state, the sensing mechanism 136 will issue a warning in time, prompting the user to check whether the right end of the moving frame 5 has fallen.

[0038] According to the above embodiment, the downward pressure of the elastic telescopic plate 132 realizes the distribution of gravity among the base frame 1, fixed frame 4 and mobile frame 5, preventing uneven stress on the overall frame caused by the driver lying on the right side of the mobile frame 5, which would increase the connection loss between the base frame 1 and the cab over time, and avoid the phenomenon of hollowing out between the connection end of the base frame 1 and the cab due to the force of the sag; through the contact detection of the sensing roller 137, it can be promptly determined whether the mobile frame 5 has detached from the drive mechanism of the fixed frame 4, thereby warning the user that the mobile frame 5 may fall when it has been used for a long time without timely maintenance, thus increasing the safety of the equipment.

[0039] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
