Description

Technical Field

[0001] This utility model relates to the field of commercial vehicle technology, and in particular to a sleeper assembly and a commercial vehicle. Background Technology

[0002] Commercial vehicles are mainly used to transport people or goods. Commercial vehicle sleeper berths are designed to meet the rest needs of commercial vehicle drivers during long-distance transportation, in order to alleviate fatigue and avoid safety hazards caused by drowsy driving. Commercial vehicle sleeper berths come in various types, such as independent sleeper berths and folding sleeper berths.

[0003] Traditional commercial vehicle sleeper berths consist of a sleeper mattress and a floor. During the assembly of a commercial vehicle sleeper berth, the floor needs to be laid on a designated area such as a storage box first, and then the sleeper mattress is placed on the floor. This process involves two assembly steps. In order to improve production efficiency and reduce labor intensity, an integrated sleeper assembly has emerged. The mattress and floor are placed together and covered with a skin on the outside to form an integrated structure. This reduces the sleeper assembly process to one step, effectively shortening the production cycle.

[0004] In existing integrated sleeper assemblies, the mattress is placed directly on the base plate, and the mattress and base plate are mainly secured by a covering. This results in poor overall stability, and the mattress and base plate are prone to shifting. Furthermore, the covering is fixed to the base plate with nails, which are often exposed and can easily come loose due to impacts. In addition, while existing integrated sleeper assemblies generally have ventilation holes to improve breathability, the mattress core is mostly made of sponge, which itself has poor breathability and easily absorbs moisture in humid weather, leading to a poor user experience. Utility Model Content

[0005] To address the technical problems in the existing integrated sleeper assemblies mentioned above, where the mattress and base plate are mainly secured by a skin covering, resulting in poor overall stability and easy displacement between the mattress and base plate, this utility model provides a sleeper assembly.

[0006] The technical solution of this utility model is as follows:

[0007] This utility model provides a sleeper assembly, including a base plate with a soft pad core fixedly mounted on it. The soft pad core and the base plate are covered with a skin. The base plate includes a plate body, with several insertion parts fixedly mounted on one side surface. The insertion parts are inserted and fixed inside the soft pad core, making the connection between the base plate and the soft pad core more stable and preventing displacement or separation during use, thus improving the overall structural stability of the sleeper assembly. The other side of the plate body is fixedly connected to the skin with fasteners to form an integrated structure, which simplifies the assembly of the sleeper assembly, improves production efficiency, and facilitates installation and disassembly by connecting the skin to the plate body with fasteners, making it easier to maintain and replace the skin or internal structure later.

[0008] Preferably, the length of the insertion part is less than the thickness of the cushion core, which can prevent the insertion part from penetrating the cushion core and avoid causing discomfort to the passenger. At the same time, it ensures the overall integrity and cushioning performance of the cushion core, allowing the user to fully feel the comfortable support provided by the cushion core when resting, greatly improving the riding experience.

[0009] Preferably, the insertion part is bonded and fixed to the cushion core, which further enhances the connection strength between the insertion part and the cushion core, reduces loosening caused by vibration or long-term use, and the solid connection between the insertion part and the cushion core makes the structure of the entire sleeper assembly more reliable, extends the service life of the sleeper assembly, reduces the frequency of maintenance or replacement due to structural loosening, and saves costs.

[0010] Preferably, a mounting groove is provided on the side surface where the plate body and the skin are fixedly connected. The end of the skin is fixedly installed in the mounting groove by fasteners. The mounting groove provides precise positioning for the installation of the skin, making the installation of the skin more convenient and secure. The mounting groove also provides a certain degree of protection for the end of the skin, preventing the edge of the skin from being damaged by external friction and extending the service life of the skin. At the same time, the mounting groove can also protect the fasteners, preventing them from being exposed to the external environment and reducing fastener damage caused by factors such as collision and corrosion, thus ensuring the stability of the connection between the skin and the plate body.

[0011] Preferably, the depth of the mounting groove is greater than the length of the fastener, which can prevent the fastener from protruding from the surface of the plate, prevent the fastener from scratching the skin or the user during use of the sleeper berth, and prevent the fastener from being exposed and falling off due to collision, thereby improving the safety and service life.

[0012] Preferably, the area of ​​the side of the panel with the mounting groove that is not covered by the skin accounts for 0.3-0.8 of the total area of ​​the side of the panel with the mounting groove. This ensures that the skin effectively covers the panel while providing a certain degree of breathability, avoiding stuffiness caused by poor air circulation due to complete coverage, thus improving user comfort. At the same time, it also reduces the amount of skin used and lowers costs.

[0013] Preferably, the cushion core is made of air fiber, which has good elasticity. When the user lies on the berth, it can effectively distribute the pressure on the body, so that all parts of the body can be evenly supported, avoiding soreness caused by excessive local pressure. At the same time, it has good breathability, which helps to keep the berth dry. During the user's rest, the heat and moisture emitted by the body can be quickly dissipated through the air fiber core, reducing stuffiness and dampness, and creating a comfortable and dry resting environment for the user.

[0014] Preferably, the insertion part has a pointed protrusion structure, which facilitates the insertion of the soft pad core, minimizes damage to the soft pad core during insertion, and allows for better bonding with the soft pad core after insertion, thus enhancing the strength of the connection.

[0015] Preferably, the cover is made of breathable textile fabric, which allows for smooth air circulation inside the sleeper berth. During long periods of rest, this effectively reduces stuffiness caused by poor air circulation, ensuring a comfortable sleeping experience. At the same time, the relatively soft textile fabric provides a comfortable touch, enhancing the user's tactile experience and contributing to improved sleep quality.

[0016] A commercial vehicle adopts the aforementioned sleeper assembly, in which the air fiber core and the floor are assembled into an integrated structure through a skin, which simplifies the assembly of the sleeper assembly, improves production efficiency, and the air fiber core and the floor are connected by an insertion part, resulting in good overall installation stability and preventing displacement and deformation between the air fiber core and the floor.

[0017] As can be seen from the above technical solutions, the advantages of this utility model are:

[0018] 1. The soft pad core and the base plate are assembled into an integrated structure through a skin, which simplifies the assembly of the sleeper assembly and improves production efficiency. The base plate is fixed with several insertion parts, which are inserted and fixed in the soft pad core, making the connection between the base plate and the soft pad core more stable and preventing displacement or separation during use, thus improving the overall structural stability of the sleeper assembly.

[0019] 2. The length of the insertion part is less than the thickness of the cushion core, which can prevent the insertion part from penetrating the cushion core and avoid causing discomfort to the passenger. At the same time, it ensures the overall integrity and cushioning performance of the cushion core, making the riding experience more comfortable.

[0020] 3. The panel is equipped with mounting grooves. The ends of the skin are fixed in the mounting grooves by fasteners. The mounting grooves provide precise positioning for the installation of the skin, making the installation more convenient and secure. The mounting grooves also provide a certain degree of protection for the ends of the skin, preventing the edges of the skin from being damaged by external friction. At the same time, the mounting grooves also protect the fasteners, preventing them from protruding from the surface of the panel and preventing them from scratching the skin or the user during use. They also prevent the fasteners from being exposed and falling off due to collisions, thus improving safety and service life.

[0021] 4. The soft padding core is made of air fiber, which has good elasticity and breathability. It can effectively distribute the pressure of the human body and provide comfortable support. At the same time, the good breathability helps to keep the bedding dry and reduce stuffiness and dampness. Attached Figure Description

[0030] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0031] Example 1

[0032] In a typical embodiment of this utility model, such as Figures 1-2 As shown, a sleeper assembly is proposed, including: a skin 1, a cushion core and a base plate 3. The cushion core is laid on the base plate 3 and is fixedly connected to the base plate 3. The skin 1 covers the outside of the cushion core and the base plate 3 and is fixedly connected to the base plate 3 by fasteners 4 to form an integrated sleeper assembly.

[0033] like Figure 3 and Figure 4 As shown, the base plate 3 includes a plate body 31 and an insertion part 32. There are several insertion parts 32. The insertion parts 32 are fixedly installed on one side surface of the plate body 31 by integral molding. The soft pad core is laid on the side surface of the plate body 31 where the insertion parts 32 are located. The insertion parts 32 are inserted into the soft pad core to play a limiting role. With the use of the skin 1, the position between the soft pad core and the base plate 3 can be effectively limited, improving the connection between the soft pad core and the base plate 3 and avoiding the problem of displacement between the two.

[0034] It is important to note that the length of the insertion part 32 should be less than the thickness of the cushion core, so as to prevent the insertion part 32 from penetrating the cushion core or the top of the insertion part 32 from being close to the surface of the cushion core. This prevents the insertion part 32 from contacting the user's body surface, ensuring the user's physical comfort, while also ensuring the overall integrity and cushioning performance of the cushion core. This allows the user to fully feel the comfortable support provided by the cushion core when resting, greatly improving the riding experience.

[0035] In this embodiment, the thickness of the plate 31 is 10-100 mm, and the density is 30-300 kg / m³. 3The insertion part 32 is a pointed protrusion structure, specifically a cone with an inclination angle of 0.5°-60°, a bottom radius of 5-20mm, a height of 10-50mm, and a center distance between adjacent cones of 50-200mm. The pointed tip makes it easier to insert into the soft pad core to fix the soft pad core and prevent it from slipping. The insertion part 32 is also fixedly connected to the soft pad core by bonding, thereby further improving the connection between the base plate 3 and the soft pad core. In this embodiment, the base plate 3 is an integral EPP foam board or glass fiber honeycomb board, which is integrally formed by molding.

[0036] To enhance comfort, the cushioning core uses air fiber core 2, which is made of highly porous thermoplastic fibers with good breathability. The thickness of air fiber core 2 is 20-200mm, and the density is 30-70kg / m³. 3 It is made of polyolefin material with a melting point of 100-250℃.

[0037] Air fiber contains numerous interconnected pores, allowing air to flow freely within them. This enhances the breathability of the mattress core, quickly dissipating heat and moisture from the body and maintaining a dry and comfortable sleeping environment. The air fiber core also adapts to the body's weight and shape, providing even support, effectively distributing body pressure, and conforming well to the body's curves. It offers excellent support for the spine, helping to maintain its natural physiological curvature, reducing pressure points during sleep, and alleviating aches and pains caused by excessive pressure on specific areas. Air fiber is highly elastic and resilient, resistant to deformation, and can withstand significant pressure and tension. Even after long-term use, it maintains its shape and performance, resulting in a long lifespan. Furthermore, air fiber has excellent resilience, quickly returning to its original shape after the body leaves the mattress without leaving noticeable indentations, continuously providing comfortable support and a sense of enclosure. In addition, the raw materials for air fiber are typically environmentally friendly, free of harmful substances, posing no health risks, and are recyclable, aligning with environmental protection principles.

[0038] There are several ways to bond the air fiber core 2 to the insertion part 32. For example, during the production of the air fiber core 2, the fiber drips directly onto the base plate 3 in a high-temperature, non-crystallized state, causing the surface of the plate 31 and the insertion part 32 to soften and melt due to heat, thereby achieving bonding and fixing of the air fiber core 2 and the base plate 3 together; or adhesive is directly applied to the surface of the plate 31 and the insertion part 32 to fix the air fiber core 2 and the base plate 3 together through the adhesive, thereby improving the connection strength between the air fiber core 2 and the base plate 3.

[0039] The skin 1 covers the outside of the air fiber core 2 and the base plate 3. In this embodiment, the skin 1 is made of a breathable woven or knitted textile fabric. The thickness of the skin 1 is 1-5mm, and the weight is 200-600g / m². 2 The skin 1 is fixedly connected to the plate 31 by fasteners 4. The use of textile fabric allows for smooth air circulation inside the berth, effectively reducing stuffiness caused by poor air circulation during long periods of rest, and ensuring a comfortable feeling for the user during sleep. At the same time, the textile fabric is relatively soft, providing a comfortable touch when the user touches the skin, enhancing the user's tactile experience and providing a certain guarantee for improved sleep quality.

[0040] like Figure 5 As shown, several insertion parts 32 are fixedly provided on one side surface of the plate 31, and an installation groove 33 is provided on the other side surface of the plate 31. The installation groove 33 is close to the side of the plate 31. The end of the skin 1 is fixedly installed in the installation groove 33 by fasteners 4. The installation groove 33 provides precise positioning for the installation of the skin 1, making the installation of the skin 1 more convenient and secure. The installation groove 33 also provides a certain degree of protection for the end of the skin 1, preventing the edge of the skin 1 from being damaged by external friction, thus extending the service life of the skin 1. At the same time, the fasteners 4 are located in the installation groove 33, so that the fasteners 4 are no longer exposed, effectively preventing the fasteners 4 from detaching due to collision, improving the firmness of the skin 1 installation, and the skin 1 does not need to be installed by removing the plate. The side of the body 31 with the mounting groove 33 is completely covered, so that only the area from the side to the mounting groove 33 on the side of the body 31 with the mounting groove 33 is covered by the skin 1 because the skin 1 is fixed in the mounting groove 33. This reduces the amount of skin 1 used and lowers the manufacturing cost. In this embodiment, the area of ​​the side of the body 31 with the mounting groove 33 that is not covered by the skin 1 is 0.3-0.8 of the total area of ​​that side (i.e. the side with the mounting groove 33). This ensures that the skin 1 effectively covers the body 31 and provides a certain degree of breathability to the body 31, avoiding stuffiness caused by poor air circulation due to complete coverage, thus improving the user's comfort. At the same time, it also reduces the amount of skin 1 used and lowers the cost.

[0041] It is understandable that the mounting slot 33 can be set near only one side or along the circumference of the plate 31. The specific setting method can be selected according to actual needs, and no further restrictions are imposed here.

[0042] In this embodiment, the width of the mounting groove 33 is 10-20mm and the depth is 1-5mm, which is used to fix the skin 1 with the fastener 4. The depth of the mounting groove 33 is greater than the length of the fastener 4, so as to hide the fastener 4 and prevent the fastener 4 from being exposed and falling off due to collision. The distance between adjacent fasteners 4 in the mounting groove 33 is 50-200mm. The fastener 4 is a fastening structure such as a rivet or screw.

[0043] Example 2

[0044] In another typical embodiment of this utility model, a commercial vehicle is proposed, which adopts the sleeper assembly in Embodiment 1. The air fiber core 2 and the bottom plate 3 are assembled into an integral structure through the skin 1, which simplifies the assembly of the sleeper assembly, improves production efficiency, and the air fiber core 2 and the bottom plate 3 are connected through the insertion part 32, so the overall installation is firm and the air fiber core 2 and the bottom plate 3 are not easy to shift or deform.

[0045] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
