Description

Technical Field

[0001] This utility model relates to a mattress, specifically a mattress suitable for use in the cab of a heavy truck, belonging to the technical field of vehicle accessories. Background Technology

[0002] In the heavy-duty truck transportation sector, drivers typically spend long hours driving, making a suitable mattress in the cab crucial for ensuring quality rest. Currently, most heavy-duty truck cabs still use mattresses with traditional spring structures, which have significant limitations in practical use. Because heavy-duty trucks often travel on unpaved roads or long-haul routes, the vehicle experiences severe vibrations during travel. Conventional spring mattresses, with their simple elastic support structure, only provide basic cushioning through spring deformation, resulting in ineffective support for the body, excessive up-and-down movement, affecting driver rest, and easily leading to muscle fatigue. Furthermore, under the combined effects of vehicle vibration and body pressure over long periods, the spring wires are prone to elastic fatigue, leading to localized collapse or loss of elasticity after prolonged use, affecting the product's lifespan. Therefore, designing a mattress with strong support and a long service life suitable for heavy-duty truck cabs has become a focus of industry research. Utility Model Content

[0003] The purpose of this invention is to provide a heavy-duty truck cab mattress. This invention reduces bumps caused by truck movement through an elastic cushioning mechanism, provides strong support, and avoids elasticity loss due to long-term use, resulting in a longer service life.

[0004] The technical solution of this utility model is as follows: A heavy-duty truck cab mattress includes a first support plate, a second support plate above the first support plate, and multiple elastic cushioning mechanisms between the second support plate and the first support plate; a load-bearing soft layer is provided above the second support plate; the elastic cushioning mechanism includes an elastic plate disposed between the first support plate and the second support plate; the elastic plate is X-shaped, and each outer end of the elastic plate is provided with a horizontal flat portion, which abuts against the first support plate or the second support plate; multiple first fixing blocks located at the outer ends of the horizontal flat portions are provided above the first support plate, and the first fixing blocks are provided with first grooves, which slide in cooperation with the horizontal flat portions below the elastic plate; multiple second fixing blocks located at the outer ends of the horizontal flat portions are provided below the second support plate, and the second fixing blocks are provided with second grooves, which slide in cooperation with the horizontal flat portions above the elastic plate.

[0005] The aforementioned heavy truck cab mattress has an elastic plate (30) and a transverse flat section (31) that are integrally formed.

[0006] The aforementioned heavy-duty truck cab mattress has a wrapping layer covering the outer side of the first support plate and the load-bearing soft layer.

[0007] The aforementioned heavy-duty truck cab mattress has multiple air holes on the second support plate.

[0008] The aforementioned heavy-duty truck cab mattress includes a base layer, a cushioning layer above the base layer, a breathable layer above the cushioning layer, and a contact layer above the breathable layer.

[0009] The aforementioned heavy-duty truck cab mattress has the following characteristics: the bottom layer is a high-density polyurethane foam layer; the cushioning layer is a slow-rebound memory foam layer; the breathable layer consists of a 3D mesh fabric and a bamboo charcoal fiber layer from top to bottom; and the contact layer is a skin-friendly cotton and linen blend fabric layer.

[0010] In the aforementioned heavy-duty truck cab mattress, the distance between the outer ends of the horizontal portions on both sides of the elastic plate is greater than the distance between adjacent second fixing blocks; the distance between the outer ends of the horizontal portions on both sides of the lower side of the elastic plate is greater than the distance between adjacent first fixing blocks; the distance between the outer ends of the upper side of the elastic plate is less than the distance between adjacent second fixing blocks; and the distance between the outer ends of the lower side of the elastic plate is less than the distance between adjacent first fixing blocks.

[0011] Compared with existing technologies, this invention has the following advantages: In this invention, when the driver lies on the supporting soft layer, the soft layer will adaptively deform to conform to the body's curves due to human body pressure, while simultaneously transmitting the pressure evenly to the second support plate below. After being subjected to force, the second support plate transmits the force to the upper end of the X-shaped elastic plate through contact with the horizontal portion above the elastic plate. Because the elastic plate has an X-shaped intersecting structure, it will elastically deform along the intersection point when subjected to force, causing the horizontal portions at the upper and lower ends to extend horizontally to both sides. During this process, the deformation of the elastic plate generates a reverse elastic force, which can effectively absorb and buffer the bumps and impacts during truck travel, and support the second support plate, reducing the amplitude of bumps. Meanwhile, the first slot of the first fixing block slides into the horizontal part below the elastic plate, and the second slot of the second fixing block slides into the horizontal part above. This not only provides guidance for the horizontal movement of the horizontal part and restricts its stable sliding along the slot direction, but also prevents the elastic plate from tilting laterally or falling out of the support position during high-frequency deformation through the blocking effect of the fixing block, thus ensuring the long-term stable operation of the buffer mechanism and avoiding elastic decay.

Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0015] Example: A heavy-duty truck cab mattress, as shown in Figures 1-5, includes a first support plate 1. As shown in Figure 2, a second support plate 2 is provided above the first support plate 1, and multiple elastic cushioning mechanisms 3 are provided between the second support plate 2 and the first support plate 1. A load-bearing soft layer 4 is provided above the second support plate 2. As shown in Figure 4, the elastic cushioning mechanism 3 includes an elastic plate 30 disposed between the first support plate 1 and the second support plate 2. Each outer end of the elastic plate 30 is provided with a horizontal flat portion 31, which is integrally formed with the elastic plate 30 to ensure uniform force transmission when subjected to force. The horizontal flat portion 31 abuts against the first support plate 1 or the second support plate 2 to achieve direct pressure transmission. In order to make the whole have better strength, the elastic plate 30 is X-shaped, and the elastic plate 30 and the horizontal flat portion 31 are integrally stamped from 65Mn spring steel. This material has excellent elastic limit and fatigue strength, and can withstand high-frequency deformation without easily decaying. Above the first support plate 1, there are multiple first fixing blocks 32 located at the outer ends of the horizontal section 31. The first fixing blocks 32 are made of wear-resistant nylon, whose wear resistance reduces wear during sliding with the horizontal section 31. Each first fixing block 32 has a first groove 33, which slides into the horizontal section 31 below the elastic plate 30. Below the second support plate 2, there are multiple second fixing blocks 34 located at the outer ends of the horizontal section 31. The second fixing blocks 34 are also made of wear-resistant nylon, and each second fixing block 34 has a second groove 35, which slides into the horizontal section 31 above the elastic plate 30. The cross-sections of the first groove 33 and the second groove 35 are rectangular. Figure 5As shown, the distance M1 between the outer ends of the horizontal portions 31 on both sides of the elastic plate 30 is greater than the distance m1 between the adjacent second fixing blocks 34, so that the horizontal portions 31 on the upper side of the elastic plate 30 will not fall out between the second fixing blocks 34 in the initial state; the distance M2 between the outer ends of the horizontal portions 31 on both sides of the lower side of the elastic plate 30 is greater than the distance m2 between the adjacent first fixing blocks 32, so that the horizontal portions 31 on the lower side of the elastic plate 30 will not fall out between the first fixing blocks 32 in the initial state; the distance N1 between the outer ends of the upper side of the elastic plate 30 is less than the distance m1 between the adjacent second fixing blocks 34, providing a margin for the deformation of the elastic plate 30 and avoiding interference; the distance N1 between the outer ends of the lower side of the elastic plate 30 is less than the distance m2 between the adjacent first fixing blocks 32, providing a margin for the deformation of the elastic plate 30 and avoiding interference. The first support plate 1 and the supporting soft layer 4 are covered with a wrapping layer 5. The wrapping layer 5 is elastic and made of neoprene rubber, which has excellent elasticity, oil resistance, and wear resistance, and can adapt to the complex environment of the cab. The wrapping layer 5 is connected to the outside of the first support plate 1 and the supporting soft layer 4 by a zipper, which facilitates the replacement of internal components. As shown in Figure 3, the second support plate 2 has multiple air holes 6. When a person lies on the mattress, when the elastic plate 30 is compressed and deformed, the gap between the first support plate 1 and the second support plate 2 narrows, and the internal air is squeezed out. The air blows through the wrapping layer 5 and the supporting soft layer 4 against the back of the person, and some of the air is discharged through the wrapping layer 5. When the elastic plate 30 rebounds and returns to its original position, the gap widens, and external air is drawn in through the wrapping layer 5, forming an air circulation, further improving the breathability and avoiding stuffiness. As shown in Figure 3, the supporting soft layer 4 includes a base layer 40, which is a high-density polyurethane foam layer with a thickness of about 2cm. Its dense internal pore structure gives it strong resilience, which can evenly distribute the pressure above to the second support plate 2, avoiding excessive local stress that could lead to collapse. Above the base layer 40 is a buffer layer 41, which is a slow-rebound memory foam layer with a thickness of about 3cm. Its material has temperature-sensitive properties and can soften as the body temperature rises, conforming to the body's curves. At the same time, it absorbs vibration energy through the slow deformation of molecular chains, converting the impact force generated by the truck's bumps into internal energy release, reducing the transmission of vibration to the human body. Above the buffer layer 41 is a breathable layer 42, which consists of a 3D three-dimensional mesh fabric and a bamboo charcoal fiber layer from top to bottom, with a thickness of about 1cm. The three-dimensional warp and weft structure of the mesh fabric forms millions of micro air channels, while the porous structure of bamboo charcoal fiber can absorb moisture and odors. Together, they accelerate air circulation and quickly expel sweat and moisture. Above the breathable layer 42 is a contact layer 43, which is a skin-friendly cotton and linen blend fabric layer. It is composed of 80% cotton and 20% linen blend fabric and is about 0.5cm thick. The moisture absorption of cotton fibers can quickly absorb sweat from the skin surface, while the tubular structure of linen fibers promotes moisture evaporation. In addition, the soft nap of the fabric surface reduces the discomfort caused by friction with the skin and improves the comfort of contact.

[0016] Working principle: When the driver lies on the mattress, the supporting soft layer 4 adapts to the body's curves under pressure, while simultaneously transmitting the pressure evenly to the second support plate 2 below. Under pressure, the second support plate 2 transmits the force to the upper end of the X-shaped elastic plate 30 through contact with the horizontal portion 31 above the elastic plate 30. Because the elastic plate 30 has an X-shaped cross structure, it undergoes elastic deformation along the intersection point under pressure, causing the horizontal portions 31 at the upper and lower ends to extend horizontally to both sides. The resulting reverse elastic force effectively absorbs and cushions the impact of bumps during truck travel and supports the second support plate, reducing the amplitude of bumps. Meanwhile, the first slot 33 of the first fixing block 32 slides with the lower horizontal part 31 of the elastic plate 30, and the second slot 35 of the second fixing block 34 slides with the upper horizontal part 31. This provides guidance for the horizontal movement of the horizontal part 31 and restricts its stable sliding along the slot direction. It also prevents the elastic plate 30 from tilting laterally or falling out of the support position during high-frequency deformation through the blocking effect of the fixing block, thus ensuring the long-term stable operation of the buffer mechanism.
