The front deck is opposite to the front end of the cushion, and the rear deck is opposite to the rear end of the cushion.

[0013] As a preferred embodiment of a heat-resistant seat cushion, there is a space between the upper end of the front deck and the front end of the cushion plate, the space being used to accommodate the deformation caused by vibration of the cushion plate.

[0014] As a preferred embodiment of a heat-resistant seat cushion, a cushioning pad is provided on the top surface of the front deck, and the cushioning pad is fixedly connected to the front deck. The cushioning pad is used to buffer the vibration of the pad.

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Furthermore, the terms "first" and "second" are used merely for descriptive distinction and have no specific meaning.

[0031] In one embodiment of this utility model, such as Figure 1-5 As shown, a heat-resistant seat cushion is provided, including: a cushion body 1 for providing riding support when a user rides an electric vehicle; the cushion body 1 includes a support seat 2 and a bottom frame 3, the support seat 2 being positioned on top of the bottom frame 3; the support seat 2 includes a heat radiation reflective layer 6, a heat conduction mitigation layer 7 and a base layer 8 stacked sequentially, the surface of the base layer 8 having a groove, the heat radiation reflective layer 6 and the heat conduction mitigation layer 7 being loaded into the groove, and the layers being bonded together.

[0032] The anti-scalding seat cushion provided by this utility model features a multi-layered support base 2. By incorporating a heat radiation reflective layer 6, it effectively blocks external heat from being transferred to the seat surface, significantly reducing the risk of burns caused by high temperatures and ensuring user safety while riding. The heat conduction mitigation layer 7 provides the anti-scalding seat cushion with good flexibility and elasticity, absorbing and cushioning the impact of road bumps during riding, reducing vibration to the user's body and improving riding comfort. The heat radiation reflective layer 6 and the heat conduction mitigation layer 7 are embedded in grooves on the surface of the base layer 8. This not only enhances the bonding strength and stability between the layers, preventing displacement or separation of key layers during use, but also optimizes the heat conduction path, forming a tighter thermal barrier, reducing heat conduction upwards from the bottom frame, and further improving the heat insulation effect and anti-scalding protection capability.

[0033] Preferably, the heat radiation reflective layer 6 is honeycomb-shaped, with the center line of each honeycomb cell parallel to the center line of the heat conduction mitigation layer 7. The honeycomb structure effectively forms a thermal barrier, reducing heat conduction. The small spaces 11 between the honeycomb cells restrict airflow, further reducing heat transfer efficiency. By aligning the center lines of the honeycomb cells with the center line of the heat conduction mitigation layer 7, i.e., with the honeycomb cells perpendicular to the surface of the heat conduction mitigation layer, consistent and efficient heat insulation performance is ensured throughout the cushion in all directions. Furthermore, the honeycomb structure enhances the strength of the heat radiation reflective layer 6 itself and, through precise alignment with the heat conduction mitigation layer 7, improves the stability and durability of the overall structure. This allows the cushion to maintain its shape and function even under prolonged use or significant pressure.

[0034] Preferably, the heat conduction mitigation layer 7 is corrugated, and the corrugated surfaces of the corrugated heat conduction mitigation layer 7 are bonded to the heat radiation reflective layer 6 and the base layer 8, respectively. The corrugated structure increases the surface area of ​​the heat conduction mitigation layer 7, thereby increasing the elastic deformation space 11. When subjected to pressure, the corrugated structure can more effectively absorb and disperse impact force, thereby significantly improving the cushioning performance of the seat. This not only improves riding comfort but also effectively reduces fatigue caused by long-distance riding.

[0035] Preferably, the heat radiation reflective layer 6 can be made of high-temperature resistant and soft ceramic fiber cotton, the heat conduction mitigation layer 7 is made of high-density polyurethane insulation cotton, and the base layer 8 is made of polyethylene foam cotton with certain waterproof properties. The layers are bonded together with environmentally friendly adhesive, effectively blocking heat transfer while maintaining good flexibility and comfort.

[0036] In some embodiments, the heat radiation reflective layer 6 may also be made of aerogel, glass fiber, and silicone rubber to enhance the heat radiation reflection effect, heat insulation effect, improve waterproof performance, and improve the flexibility and adaptability of the structure.

[0037] The anti-scalding principle in this embodiment is as follows: the honeycomb structure makes each hexagonal prism-shaped honeycomb unit an independent air chamber. Since air is a poor conductor of heat, the large number of air chambers closely arranged form a dense thermal resistance barrier. When external heat is transferred to the cushion, it first comes into contact with the honeycomb ceramic fiber cotton layer. The heat needs to be continuously reflected and refracted in the numerous air chambers, greatly prolonging and complicating the heat transfer path, thereby reducing the rate of heat conduction and effectively blocking heat from being transferred to the human body, thus playing a preliminary role in preventing scalding.

[0038] The heat radiation reflective layer 6 is made of ceramic fiber, which itself has certain heat radiation reflective properties. The honeycomb structure increases the surface area of ​​the fibers, enabling them to more effectively reflect heat radiation from the outside world. For example, in high-temperature environments, when solar heat radiation or heat radiation emitted by hot objects shines on the cushion, the honeycomb ceramic fiber cotton layer can reflect some of the heat radiation back, reducing the heat absorbed and conducted, and further improving the anti-scalding effect.

[0039] Furthermore, the wavy polyurethane insulation material disrupts the straight-line heat transfer path. As heat is conducted downwards from the ceramic fiber layer to the polyurethane insulation layer, it must meander between the crests and troughs. This complex path prolongs the heat transfer time. According to the heat conduction formula, under the same temperature difference, the longer the heat transfer time, the less heat is transferred per unit time, thus reducing heat conduction efficiency and further hindering heat transfer to the body, thereby enhancing the anti-scalding performance.

[0040] Furthermore, the wave-shaped structure creates multiple tiny air buffer zones between the crests and troughs. These air zones act like small heat insulation units, further hindering heat conduction. The low thermal conductivity of air slows down heat transfer as it passes through these zones. Simultaneously, when the cushion is subjected to external heat impact, these air buffer zones can absorb some of the heat, providing both cushioning and insulation. Together with the honeycomb ceramic fiber cotton layer, they enhance the overall heat-resistant effect of the cushion.

[0041] The honeycomb-shaped ceramic fiber cotton layer and the corrugated polyurethane insulation cotton layer are tightly bonded together to form a composite thermal resistance system. The air chambers of the honeycomb structure and the heat-reflective properties of the ceramic fibers work together with the tortuous heat conduction path and air buffer areas of the corrugated structure. As heat is transferred from the outside to the human body, it must overcome the thermal resistance of the two layers in turn, which greatly increases the difficulty of heat transfer and thus improves the anti-scalding ability of the cushion.

[0042] When the seat cushion is subjected to localized high-temperature impact, the flexibility of the honeycomb ceramic fiber cotton layer and the elasticity of the wavy polyurethane insulation cotton layer allow the two-layer structure to adaptively adjust its shape. For example, in high-temperature areas, the honeycomb units and wavy structure will deform to a certain extent, further increasing the density of the air chambers and buffer areas, enhancing the heat insulation effect, achieving effective protection against localized high temperatures, and providing users with comprehensive and reliable anti-scalding protection.

[0043] This eliminates the need for a removable protective cover, simplifying the product structure and reducing production and maintenance costs.

[0044] This heat-resistant seat cushion also includes a pad 9, which is located at the bottom of the base frame 3. By using the pad 9, the entire seat cushion is securely mounted on the electric vehicle seat frame, preventing displacement or loosening due to vibrations or impacts during riding. This stable installation method not only improves safety but also enhances the user's riding experience.

[0045] This heat-resistant seat cushion also includes a panel assembly 10 disposed on the edge of the pad 9, and the panel assembly 10 extends in a direction away from the pad 9. By being disposed around the edge of the pad 9 and extending in a direction away from the pad 9, the panel assembly 10 not only enhances the overall structural strength of the entire seat cushion, but also provides additional support and protection to prevent external impacts from damaging the internal structure.

[0046] Specifically, the panel assembly 10 includes side decks 101, a front deck 102, and a rear deck 103. The side decks 101 are symmetrically positioned on both sides of the pad 9. The front deck 102 and the rear deck 103 are respectively connected to the two ends between the opposite side decks 101. The front deck 102 is opposite to the front end of the pad 9, and the rear deck 103 is opposite to the rear end of the pad 9. By setting symmetrical side decks 101 on both sides of the pad 9 and connecting the front deck 102 and the rear deck 103 at both ends, a robust integral frame is formed. This not only enhances the overall rigidity and durability of the cushion but also effectively prevents damage to the internal components from external impacts, ensuring that the cushion maintains stable performance during long-term use.

[0047] Preferably, when installing the front deck 102 and the rear deck 103, the front deck 102 and the rear deck 103 can be connected to the two ends between the opposite side decks 101 by a snap-fit ​​connection. This avoids drilling holes in the pad 9, thus maintaining the integrity and strength of its structure and preventing potential weaknesses or stress concentration points caused by drilling, thereby extending the service life of the cushion.

[0048] Specifically, a space 11 exists between the upper end of the front deck 102 and the front end of the pad 9. This space 11 accommodates the deformation of the pad 9 due to vibration. By reserving this space 11 between the front deck 102 and the front end of the pad 9, the pad 9 is allowed a certain degree of freedom in deformation when subjected to vibration, thereby effectively absorbing and buffering vibrations from the road surface. This not only protects the internal structure from excessive stress but also improves the overall vibration resistance of the seat cushion, ensuring durability and reliability for long-term use.

[0049] Preferably, a cushioning pad 12 is provided on the top surface of the front deck 102. The cushioning pad 12 is fixedly connected to the front deck 102. The cushioning pad 12 can effectively absorb and disperse the vibration energy from the pad 9, reducing the amount of vibration transmitted to the user's body. This additional heat-conducting damping layer 7 further improves the shock absorption performance of the saddle. Not only can it reduce the impact force on the internal structure by absorbing and dispersing vibration energy, thus extending the service life of the entire saddle and its components, it also ensures a smooth and comfortable riding experience under various road conditions.

[0050] This heat-resistant seat also includes a handrail assembly 13, which is located on the side deck 101. The handrail assembly 13 provides a stable hand support point for the user, which can help the user or the passenger to maintain better balance and control the direction during riding, especially when starting, stopping or turning, thereby improving the safety of riding.

[0051] Specifically, the handrail assembly 13 includes a mounting block 14 and a handlebar 15. The mounting block 14 is positioned on the side plate 101, and the handlebar 15 is rotatably positioned on the mounting block 14. The handlebar 15 extends to the pad body 1 and rotates in a direction perpendicular to the pad body 1. The handlebar 15 can rotate about a direction perpendicular to the pad body 1, allowing the user to easily adjust the angle of the handlebar 15 according to personal needs or riding posture to find the most comfortable grip position. This flexibility not only improves the comfort of use but also adapts to the body shape and preferences of different users.

[0052] In this embodiment, a backrest 16 can also be installed on the rear deck 103. The backrest 16 provides users with additional lumbar or back support, which can significantly reduce pressure on the waist and back, reduce fatigue, and provide a more comfortable sitting experience, especially during long-distance riding.
