Description

Technical Field

[0001] This invention belongs to the technical field of commercial vehicle parts, specifically relating to an electric widened sleeper berth for commercial vehicles. Background Technology

[0002] In existing technologies, commercial vehicle sleeper berths generally have a fixed width, while those that support width expansion are almost all manually assembled, which suffers from numerous drawbacks such as cumbersome operation, poor appearance, and the storage space occupied by the assembled sections. However, with the rapid development of the logistics industry and the improvement of people's living standards, the existing width of ordinary commercial vehicle sleeper berths and the existing manual widening methods are gradually failing to meet users' higher demands for the convenience and overall aesthetics of the driver's cab. Therefore, the commercial vehicle market urgently needs a sleeper berth that is comfortable to lie down in, easy to operate, and electrically expandable, which, together with electric seats and electric tables in the cabin, can realize more application scenarios to adapt to the increasingly younger user group and their rich and personalized needs.

[0003] To address the aforementioned problems, this invention provides an electric widened sleeper berth for commercial vehicles. Summary of the Invention

[0004] This invention proposes an electrically widened sleeper berth for commercial vehicles, which can electrically adjust the width of the sleeper berth. While ensuring structural strength, the sleeper berth has a very considerable widening ratio, greatly improving the comfort of lying down and resolving the contradiction between users' demand for a large sleeper berth and the limited longitudinal space of the cabin.

[0005] To address the aforementioned technical problems, the present invention provides an electric widened sleeper berth for commercial vehicles, characterized in that it includes:

[0006] Storage box;

The slider and the follower slide rail are both located at the bottom of the widened frame, and the slider slides on the follower slide rail.

[0010] Preferably, the widening frame includes a variable-spacing widening frame and a sliding widening frame. The variable-spacing widening frame and the sliding widening frame each include multiple longitudinal beams and share one of the longitudinal beams. The sliding widening frame also includes a crossbeam.

[0011] The scissor lift mechanism is connected to the variable-pitch widened frame, and the crossbeam is movably connected through a sleeve set on the variable-pitch widened frame.

[0012] Preferably, the follower slide rail is disposed on the crossbeam, and the slider is fixed to the longitudinal beam.

[0013] Preferably, it also includes a sleeping pad, a fabric layer, and a roll-up mechanism.

Detailed Implementation

[0040] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0041] In this specification, it should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0042] like Figure 1 , Figure 8 , Figure 9 , Figure 10 As shown, in order to solve the above-mentioned technical problems, the present invention provides an electric widened sleeper berth for commercial vehicles, which is located in the sleeper berth installation environment space 1, and includes:

[0043] Storage box 3;

[0044] Side support assembly 5 is disposed on the side end of the storage box 3 and defines a widening path with the side wall of the storage box 3;

[0045] The widened berth assembly 2 is movably positioned above the storage compartment 3 and can be flipped. The widened berth assembly 2 can move along the widened path. Specifically, the widened berth assembly 2 is connected to the storage compartment 3 via a hinge 4. A combination of a double-crank connecting rod hinge and a gas spring is used between the widened berth assembly 2 and the storage compartment 3, enabling the berth to both flip and have assisted flipping capabilities. The berth flipping and assisted flipping functions facilitate users in flipping the berth and accessing items inside the berth compartment.

[0046] Based on the above, specifically, such as Figure 2 , 3 As shown in Figure 4, the widened berth assembly includes a widened frame 21, a scissor mechanism 22, an electric actuator bracket 26, an electric actuator 27, a slider 28, and a follower slide rail 29. The scissor mechanism 22 is connected to a portion of the widened frame 21. The electric actuator 27 is mounted on the electric actuator bracket 26, which is mounted on the widened berth assembly 2. The slider 28 and the follower slide rail 29 are both mounted at the bottom of the widened frame 21, and the slider 28 slides on the follower slide rail 29.

[0047] The electric actuator applies its pushing and pulling force directly to the central longitudinal beam, which then transmits the force to the remaining beams via a scissor mechanism connected to the bottom of each beam. For the electric actuator, applying force to the central beam ensures both a low stroke requirement and a low thrust requirement (for example, with a total width increase of 350mm in this patent, the electric actuator stroke only needs to be no less than 175mm). For the scissor mechanism, applying force to the central beam evenly distributes the force, preventing damage due to excessive stress. Furthermore, the electric actuator has a self-locking structure; power-off self-locking ensures basic safety. Secondly, if the berth is obstructed by foreign objects or significant external force during retraction, the berth controller will detect abnormal motor speed, disconnect the circuit, stop the berth's retraction, and issue a signal to alert the occupants via the audio equipment in the driver's cab. Based on the electric widening of the sleeper berth and the electric seats, the cabin has a linkage control function, that is, the seats automatically move forward when the sleeper berth is widened and automatically move backward when the sleeper berth is narrowed.

[0048] The scissor lift mechanism 22 is the main structure for transmitting the widening power and achieving uniform widening of the berth. The variable-spacing longitudinal beams are connected by a scissor lift structure, ensuring that all longitudinal beams move synchronously and with uniform gaps. Each connecting part inside the scissor lift mechanism has a graphite flange copper sleeve and a graphite copper washer, providing automatic lubrication to the hinged parts and preventing excessive friction. In a preferred embodiment, the scissor lift mechanism 22 can be configured in two groups, left and right. Each group of scissor lift mechanisms 22 consists of 14 identical connecting rods, forming eight equally spaced intersections in the middle. Each intersection is fixed to multiple longitudinal beams of the berth, ensuring that all longitudinal beams move synchronously and with uniform gaps. The first intersection is installed on the rear longitudinal beam of the berth frame, and the last intersection is installed on the last variable-spacing longitudinal beam, which is also the first sliding crossbeam. Since the middle longitudinal beam is the first load-bearing beam, the scissor lift mechanism before the middle longitudinal beam is under tension, while the scissor lift mechanism after the middle longitudinal beam is under compression. This evens out the force on the scissor lift mechanism, preventing damage due to excessive stress.

[0049] The slider rail is made of stainless steel, and the slider has built-in balls and oil plates to ensure smooth sliding.

[0050] Based on the above embodiments, another embodiment is as follows: Figure 5 , Figure 6 As shown, the widened frame 21 includes a variable-pitch widened frame 211 and a sliding widened frame 212. The variable-pitch widened frame 211 and the sliding widened frame 212 each include multiple longitudinal beams 213, sharing a common longitudinal beam. The sliding widened frame 212 also includes a crossbeam 214. The scissor mechanism 22 is connected to the variable-pitch widened frame 211, and the crossbeam 214 is movably connected via a sleeve 215 mounted on the variable-pitch widened frame 211. The slider 28 is mounted on the longitudinal beam 213, and the follower slide rail 29 is mounted on the crossbeam 214. The end of the follower slide rail 29 is fixed to the innermost longitudinal beam 213, while the remaining positions of the slide rail 29 are not fixed, only forming an assembly relationship with the other longitudinal beams 213 through the slider 28 it is fitted with. The slider 28 is fixed to the longitudinal beam 213. The sleeve structure has lubrication or ball bearings to ensure smooth sliding of the crossbeam within the pin during frame translation.

[0051] The variable-spacing widening section can include 7 longitudinal beams, achieving berth widening by changing the distance between these beams. The sliding widening section includes 4 longitudinal beams and 6 transverse beams, with each beam relatively fixed, while the entire section moves laterally as the variable-spacing widening section widens. Together, they provide the structural basis for berth widening. The combination of the variable-spacing and sliding widening sections achieves berth widening and ensures sufficient structural strength. The 6 transverse beams of the sliding section of the berth frame are laterally inserted into the sleeve 215 structure within the sliding section. Regardless of whether the berth is widened or narrowed, each transverse beam of the sliding section is fitted into at least two sleeves 215, ensuring high structural strength and rigidity at the front end of the berth. Of course, the number of transverse and longitudinal beams can be freely selected based on the space available in the commercial vehicle. Furthermore, the 7th longitudinal beam of the variable-spacing widening section is the 1st transverse beam of the sliding widening section, serving to transmit the widening stroke. The structural rigidity and stability of the two-part frame are ensured by the six crossbeams among the multiple sleeves and pins below the longitudinal beams.

[0052] Specifically, the slider 28 is installed on the longitudinal beam of each berth frame, serving to connect the longitudinal beam and the slide rail. The berth widening assembly 2 is connected to the berth storage box 3 through the berth flipping hinge 4. When the berth widening assembly 2 is laid flat, the follower slide rail 29 contacts the berth box surface. When flipped, the flipping hinge 4 bears all the pressure of the berth widening assembly 2.

[0053] Based on the above embodiments, specifically, as follows: Figure 3 As shown, it also includes a berth mat 23, a fabric layer 24, and a roll-up mechanism 25. The berth mat 23 is laid on top of the widened berth assembly 2, the fabric layer 24 is located on top of the berth mat 23, and the roll-up mechanism 25 is disposed on the widened berth assembly 2 for storing the fabric.

[0054] Specifically, as an embodiment of the prior art, the winding mechanism 25 includes a winding box, a coil spring, and a winding rod. The winding box is used to store the fabric layer. The winding box is installed on the innermost longitudinal beam. The winding rod is installed inside the winding box. The two are connected by a coil spring to provide winding force.

[0055] The fabric winding mechanism is installed on the rear crossbeam of the sleeper berth. The winding box is used to wind up and release a portion of the sleeper berth fabric, the coil spring ensures that the fabric always has a certain pre-tension, and the winding rod ensures that the tension is evenly distributed along the length. The cooperation of these three components ensures that a portion of the sleeper berth fabric can be wound up and released, avoiding fabric accumulation, wrinkles, jamming, and excessive tightness of the sleeper berth, thus assisting in achieving the function of widening the sleeper berth. The sleeper berth 23 can be made of a certain thickness of shaped cotton to ensure that it has a certain rigidity and can be laid directly on the sleeper berth frame without collapsing.

[0056] Specifically, such as Figure 12 , Figure 13 As shown, the sleeper pad 23 includes a variable portion 231 and a regular portion 232. The variable portion 231 is provided with diamond-shaped holes and can extend and retract with the widened frame 21. The bottom of the sleeper pad is fixed to the longitudinal beam of the sleeper widening frame and widens as the frame widens. The portion of the sleeper pad above the variable-spacing widened frame has evenly distributed diamond-shaped holes and can extend and retract with changes in the frame spacing; the portion of the sleeper pad above the sliding widened frame is in a regular shape and does not participate in the extension and retraction.

[0057] The sleeper mat is uniformly widened to prevent uneven density caused by compression and subsequent expansion under heavy loads, thus improving lying comfort. Furthermore, there is no relative sliding between the sleeper mat and the widened frame, preventing dynamic friction and ensuring the mat widens even under pressure, while significantly extending its lifespan.

[0058] Based on the above embodiments, such as Figure 4 As shown, the side support assembly 5 includes a fixed slide rail 51 and a support bracket 52. The fixed slide rail 51 is disposed on the support bracket 52, and the support bracket 52 is disposed on both sides of the storage box 3.

[0059] Specifically, a sliding rail groove 34 is provided above the storage box 3, and the following sliding rail 29 corresponds to it. The sleeper berth guide rail is divided into two sections, front and rear. One section is installed on the sleeper assembly and is a following sliding rail, which can rotate with the sleeper berth. The other section is installed on the side wall of the cab and is a fixed sliding rail 51, which does not rotate with the sleeper berth. This structure can, on the one hand, avoid the cantilever structure after the sleeper berth is widened, ensuring the safety and reliability of the sleeper berth; on the other hand, it can ensure that the sleeper berth can be rotated normally in the narrowed state, and achieve self-locking in the widened state to prevent personnel from accidentally rotating it. The following sliding rail is fixed to the sleeper berth crossbeam and rotates with the sleeper berth; the fixed sliding rail is installed on the mounting bracket of the side wall and does not move with the sleeper berth. The following sliding rail and the fixed sliding rail are combined in front and behind to form a long sliding rail. The slider can slide smoothly on the two parts of the sliding rail to support the sleeper berth to a larger width. As one embodiment, four follower slide rails 29 can be selected, installed on the left side of the left compartment 33, the right side of the right compartment 31, and both sides of the middle compartment 32. Two fixed slide rails 51 are installed on the side support brackets 52 on the side wall of the cab, with their rear ends connected to the follower slide rails 29, ensuring that the slider 28 can slide smoothly on both slide rails. The selection of the lengths of the two slide rails needs to be determined based on the position of the slider 28 when the berth is in its narrowest state, ensuring that the slider 28 completely disengages from the fixed slide rail 51 when the berth narrows, to allow for the overall rotation of the berth; while when the berth is in its widened state, some sliders 28 need to be positioned on the fixed slide rail 51 to lock the berth in the rotation direction, preventing accidental damage to the berth and other systems.

[0060] The sleeper berth has multiple storage compartments underneath, such as... Figure 7 As shown, storage compartment 3 includes a right compartment 31, a middle compartment 32, and a left compartment 33. The number of compartments can be increased or decreased depending on the available space. Corresponding mounting holes are provided to accommodate the widened berth assembly and the tilting mechanism. The compartments can be made of EPP material. The berth compartment may contain a metal frame, and all mounting points on the compartment are connected to the metal frame, ensuring the structural strength of the berth compartment and the installation strength of the fixed slide rails. The berth compartment has mounting points at the bottom. Installing the berth compartment on installation environment 1 (floor) maximizes the utilization of the internal space, providing considerable storage space. The high utilization of the internal space allows users to store a large number of items and also allows manufacturers to install additional cabin functions within the berth compartment.

[0061] This invention features an electrically adjustable sleeper berth, primarily enabling electric adjustment of the berth width. Combined with a seat equipped with sliding rails, it maximizes the use of longitudinal space within the cab, meeting the design requirement of accommodating an extra-wide sleeper berth within a limited cab space. Furthermore, the berth widening process is fully electric and can be controlled via buttons, voice commands, a mobile app, gestures, and the vehicle's infotainment system.

[0062] Other alternative embodiments of the present invention are also available, which will not be described in detail here.

[0063] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for the present invention. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
