A ventilated and heat-dissipating seat cushion

Abstract

This utility model discloses a ventilated and heat-dissipating seat cushion, relating to the field of seat cushion technology. It includes a rectangular grid plate, with a support unit at each cross intersection of the grid plate. Each support unit includes a ring-shaped body, with four support rods fixed at equal intervals at the bottom of the ring-shaped body. The lower ends of the four support rods are respectively fixedly connected to the four rods at the corresponding cross intersections. Each support unit on the edge of the seat cushion has a protective unit, which includes two bent rods fixed to the outer edge of the ring-shaped body. The lower ends of the two bent rods are fixed to the same connecting rod, which is fixedly connected to the grid plate. This ventilated and heat-dissipating seat cushion, by setting support units at each cross intersection of the grid plate, creates a flexible support system between the grid plate and the support units, which can deform to a certain extent. This significantly improves the cushion's flexibility while also enhancing ventilation and heat dissipation, thus improving comfort.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Example 1: This Example 1 provides a ventilated and heat-dissipating seat cushion, which is a direct improvement on an existing seat cushion. It has a unique structure. Please refer to [link / reference]. Figure 1-7As shown, the structure includes a grid plate 1, a support unit 2, and a protective unit 3. The support unit 2 is evenly distributed at each intersection of the grid plate 1, and the protective unit 3 is correspondingly set on the support unit 2 at the edge of the seat cushion. The three are made of one piece using a molding process to ensure structural stability. The cross intersection of the rectangular grid plate 1 serves as the installation reference for the support unit 2. The grid plate 1 is made of modified polypropylene material, which has good compressive strength, weather resistance, and lightweight characteristics, making it suitable for the usage environment requirements of electric vehicle seats.

[0022] The support unit 2 consists of a ring body 21 and a support rod 22. There are various options for the ring body 21, such as square, circular, octagonal, hexagonal, etc. In this solution, an octagonal structure is adopted, and the line connecting its center and the cross intersection point of the corresponding grid plate 1 is perpendicular to the plane of the grid plate 1. This perpendicular setting can ensure that the support force of the support unit 2 on the rider's buttocks is evenly transmitted to the grid plate 1, avoiding structural deformation caused by local force concentration.

[0023] There are at least two support rods 22, and four are provided in this application. All of them are fixed to the bottom of the ring body 21, and the four support rods 22 are arranged in a ring array based on the center of the ring body 21. The lower end is fixedly connected to the four rods at the cross intersection, which improves the support stability and can maintain a good support effect even during the frequent bumpy riding process of the rider. The protective unit 3 includes two bent rods 31 and one connecting rod 32. The bent rods 31 are L-shaped rods or arc rods. The bent rods 31 are symmetrically fixed to the outer edge of the ring body 21, and the top surface of the two bent rods 31 is flush with the top surface of the ring body 21. This flush design can ensure that the rider's buttocks feel flat when contacting the seat, avoiding discomfort caused by height difference. It can play a protective role and improve the comfort of use.

[0024] The lower ends of the two bent rods 31 are fixedly connected to the same connecting rod 32. The connecting rod 32 is fixedly connected to the edge of the grid plate 1 to form a circumferential protective structure for the edge of the cushion. The setting of the protective unit 3 can effectively prevent foreign objects from directly impacting the support unit 2, thus protecting the support unit 2 and extending the service life of the cushion. The grid plate 1, support unit 2 and protective unit 3 adopt an integrated molding design, and the connection between each component is firm.

[0025] Working principle: When in use, place the seat cushion on the upper surface of the bicycle seat, and fix the seat cushion to the seat by passing the rope through the mesh gaps of the mesh plate 1 to prevent the seat cushion from shifting during riding. At this time, the mesh plate 1 is in direct contact with the surface of the bicycle seat, and the support unit 2 protrudes upward to form a support structure for the rider's buttocks. When the rider sits on the seat cushion, the buttocks contact the annular body 21 of the support unit 2, and a gap space is formed between the mesh plate 1 and the buttocks by the support unit 2. During the electric vehicle's operation, air can circulate freely through the cross mesh channels of the mesh plate 1 and the gap between the support unit 2, carrying away the heat and sweat generated at the contact area between the buttocks and the seat cushion, achieving a good ventilation and heat dissipation effect, and effectively solving the problem of stuffiness and discomfort caused by poor ventilation between the seat and the buttocks.

[0026] The octagonal ring 21 of the support unit 2 increases the contact area with the buttocks, reduces local pressure, and improves riding comfort; the four support rods 22 form a stable support structure that can withstand greater pressure without easily deforming, ensuring long-term reliability; the edge protection unit 3 enhances the structural strength of the seat edge and prevents the edge from being damaged by force.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
