Description

Technical Field

[0001] This utility model relates to the field of automotive parts, and in particular to a car backrest mesh. Background Technology

[0002] With the rapid development of the automotive industry, people's requirements for the comfort and functionality of car interiors are increasing day by day. As a key component that comes into direct contact with the body of drivers and passengers, the design rationality of the car backrest directly affects the driving and riding experience.

[0003] Currently, the mesh structure used in most car backrests on the market has a significant drawback: it lacks effective partitioning for the lumbar and back areas. During daily driving and riding, the stress on the lumbar and back areas differs significantly. The lumbar region, as the main support point of the upper body, bears considerable pressure and requires stable support that conforms to the physiological curve. However, the existing unpartitioned mesh backrests cannot accurately provide targeted support for the lumbar region, easily leading to prolonged tension in the lumbar muscles. Over time, this can cause problems such as lumbar pain and fatigue. At the same time, the back area, due to its large area and irregular shape, requires a structure that can distribute pressure and provide even support. However, the existing uniform mesh design cannot meet the differentiated support needs of different parts of the back, causing localized numbness and poor blood circulation after prolonged pressure, greatly reducing driving and riding comfort.

[0004] In conclusion, the existing car backrest mesh has obvious shortcomings in structural design and cannot meet people's pursuit of a comfortable driving experience. Therefore, developing a new type of car backrest mesh with lumbar and backrest partitioning functions that can adapt to the needs of different groups of people has important practical significance and market value. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a car backrest mesh.

[0006] The automotive backrest mesh provided by this utility model adopts the following technical solution:

[0007] A car backrest mesh includes side bars, several connecting steel wires, a waist area, a back area, and a partition area located between the waist area and the back area. The waist area, the back area, and the partition area are connected to the side bars by the connecting steel wires. The waist area and the back area adopt different mesh structure designs. The waist area adopts a diamond double-layer mesh structure, and the back area uses a hexagonal single-layer breathable mesh structure.

[0008] Optionally, the upper layer of the waist region is made of highly elastic TPU material, and the lower layer is made of glass fiber reinforced nylon material, and the mesh density of the waist region is increased by 30% compared with conventional mesh.

[0009] Optionally, the back area material is elastic polyester fiber, and the mesh aperture of the back area is 20% larger than that of a conventional mesh.

[0010] Optionally, the dividing area is a physical dividing component provided between the waist area and the back area to clearly distinguish between the waist area and the back area. The dividing component is a soft dividing strip or a hard dividing plate.

[0011] Optionally, two sets of micro-inflatable bladders are embedded in the grid surface of the waist region, and the micro-inflatable bladders are evenly distributed along the waist curve.

[0012] Optionally, a seat pressure sensor is also included. The miniature airbag is linked to the seat pressure sensor. When the seat pressure sensor detects changes in the occupant's sitting posture and pressure distribution, it automatically adjusts the air pressure of the miniature airbag to provide appropriate lumbar support.

[0013] Optionally, it also includes a control unit connected to the seat pressure sensor and the miniature airbag, the control unit based on data transmitted by the seat pressure sensor.

[0014] Optionally, the mesh surfaces of the waist and back areas are coated with an antibacterial and antifouling coating, which is a composite of nano-silver ion antibacterial material and fluorocarbon antifouling material.

[0015] In summary, this utility model has at least one of the following beneficial technical effects:

[0016] 1. Side bars and connecting steel wires are used to construct a stable support frame, ensuring the overall stability of the backrest mesh. The lumbar and back areas adopt different mesh structures. The diamond double-layer mesh in the lumbar area specifically strengthens the support for the lumbar region, which is suitable for the lumbar region to bear greater pressure. The hexagonal single-layer breathable mesh in the back area is more suitable for the large area and irregular shape of the back, dispersing pressure and providing even support. This solves the problem that the existing unpartitioned backrest mesh cannot accurately provide support for the lumbar and back, thus improving driving and riding comfort.

[0017] 2. The upper layer of high-elasticity TPU material in the lumbar region offers excellent flexibility and resilience, closely conforming to the physiological curves of the waist and distributing pressure. The lower layer of glass fiber reinforced nylon material provides high strength and rigidity, ensuring it remains undeformed under significant pressure. A 30% increase in mesh density further enhances vertical rigidity support. The back area utilizes elastic polyester fiber, whose excellent elasticity adapts to back movements. A 20% increase in mesh aperture significantly improves airflow, resolving the issues of localized numbness and poor blood circulation in the lower back caused by prolonged pressure in existing uniform mesh designs.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0022] Furthermore, "several" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0023] This utility model discloses a car seatback mesh. (Refer to...) Figure 1 A car backrest mesh includes side bars 1, several connecting wires 2, a lumbar region 3, a back region 4, and a partition 5 located between the lumbar region 3 and the back region 4. The lumbar region 3, the back region 4, and the partition 5 are connected to the side bars 1 by the connecting wires 2. The lumbar region 3 and the back region 4 adopt different mesh structure designs. The lumbar region 3 adopts a diamond-shaped double-layer mesh structure, while the back region 4 adopts a hexagonal single-layer breathable mesh structure. Through this design, the side bars 1 and the connecting wires 2 construct a stable support frame, ensuring the overall stability of the backrest mesh. The lumbar region 3 with its diamond-shaped double-layer mesh specifically strengthens the support for the lumbar region, which is suitable for the lumbar region to bear greater pressure. The back region 4 with its hexagonal single-layer breathable mesh is more suitable for the large area and irregular shape of the back, dispersing pressure and providing uniform support. This solves the problem that existing unpartitioned backrest meshes cannot accurately provide support for the lumbar and back, thus improving driving and riding comfort.

[0024] The upper layer of the waist zone 3 is made of high-elasticity TPU material, and the lower layer is made of glass fiber reinforced nylon material. The mesh density of the waist zone 3 is 30% higher than that of a conventional mesh. The back zone 4 is made of elastic polyester fiber, and the mesh aperture of the back zone 4 is 20% larger than that of a conventional mesh. The high-elasticity TPU material in the upper layer of the waist zone 3 has good flexibility and resilience, which can closely conform to the physiological curve of the waist and distribute pressure. The lower layer of glass fiber reinforced nylon material provides high strength and rigidity, ensuring that it will not deform under greater pressure. The 30% increase in mesh density further strengthens the vertical rigidity support. The elastic polyester fiber used in the back zone 4 has good elasticity to adapt to back movements. The 20% increase in mesh aperture significantly improves air circulation and solves the problem of local numbness and poor blood circulation in the lower back caused by prolonged pressure under the existing uniform mesh design.

[0025] The dividing zone 5 is a physical dividing component set between the waist zone 3 and the back zone 4. It is used to clearly distinguish between the waist zone 3 and the back zone 4. The dividing component is either a soft dividing strip or a hard dividing plate. Whether it is a soft dividing strip or a hard dividing plate, it can clearly distinguish between the waist zone 3 and the back zone 4, prevent the functions of the two areas from interfering with each other, and ensure that the waist zone 3 and the back zone 4 can independently perform their respective design functions, accurately providing support for the waist and back, and avoiding the confusion in the functional implementation of the existing undivided backrest grid.

[0026] Two sets of miniature airbags 6 are embedded in the mesh surface of the lumbar region 3. The miniature airbags 6 are evenly distributed along the lumbar curve. The outside of the mesh also includes a seat pressure sensor and a control unit. The miniature airbags 6 are linked with the seat pressure sensor. When the seat pressure sensor detects changes in the occupant's sitting posture and pressure distribution, it automatically adjusts the air pressure of the miniature airbags 6 to provide appropriate lumbar support. The control unit, based on the data transmitted by the seat pressure sensor, can dynamically adjust the support of the miniature airbags 6 according to changes in lumbar pressure and posture. The even distribution ensures that all parts of the lumbar region receive appropriate support, improving the lumbar stress situation and solving the problem of single and inaccurate lumbar support provided by existing backrest meshes. It also reduces the burden on the lumbar muscles. The linkage between the seat pressure sensor and the miniature airbags 6 can detect changes in the occupant's sitting posture and pressure distribution in real time and automatically adjust the air pressure of the miniature airbags 6 to provide appropriate lumbar support. The control unit controls the inflation and deflation of the miniature airbags 6 based on the data transmitted by the seat pressure sensor, achieving precise control and dynamic adjustment of the lumbar support force. This further enhances the intelligence and reliability of the lumbar support system and optimizes the lumbar support effect.

[0027] The mesh surfaces of the waist area 3 and the back area 4 are coated with an antibacterial and anti-fouling coating. The antibacterial and anti-fouling coating is made of nano silver ion antibacterial material and fluorocarbon anti-fouling material. The nano silver ion antibacterial material inhibits bacterial growth, keeps the area clean and hygienic, and prevents odors and the spread of diseases.

[0028] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
