Description

Technical Field

[0001] This utility model relates to the field of backrest frame technology, and in particular to a backrest frame with ventilation and heat dissipation function. Background Technology

[0002] The backrest frame is the core support structure of the chair, mainly used to fix the shape of the seat back, bear the pressure of the human back, and provide a mounting base for the seat fabric, foam, and functional components (such as headrests and lumbar supports). It is usually made of metal alloys (such as steel and aluminum alloys) or high-strength engineering plastics, combining support stability with lightweight characteristics. Some frames are also optimized for structural strength through processes such as stamping and welding to prevent deformation over long-term use.

[0003] Therefore, we proposed a backrest frame with ventilation and heat dissipation functions to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a backrest frame with ventilation and heat dissipation functions, which solves the obvious shortcomings of some backrest frames in the prior art: on the one hand, the surface of the frame is prone to local high temperature areas due to heat accumulation, especially when leaning against it for a long time, the heat is difficult to dissipate effectively; on the other hand, the traditional structure blocks air circulation, which leads to obstructed air circulation inside the seat, resulting in poor breathability and making the user's back feel stuffy.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A backrest frame with ventilation and heat dissipation function includes a frame body, the frame body includes two backrest frames, an upper crossbeam and a lower crossbeam, the upper crossbeam is fixedly installed at the top between the two backrest frames, the lower crossbeam is fixedly installed at the bottom between the two backrest frames, a first heat dissipation mechanism for ventilation and heat dissipation inside the frame body is fixedly installed at the bottom of each of the two backrest frames, and a second heat dissipation mechanism for ventilation and heat dissipation inside the frame body is also provided on the surface of the two backrest frames.

[0006] As a preferred embodiment of the above technical solution, the first heat dissipation mechanism includes a mounting groove, the bottom of the backrest frame is provided with a mounting groove, and the surface of the mounting groove is provided with bolt holes. The bottom of the mounting groove is provided with a mounting bracket, and the mounting bracket is fixedly installed on the surface of the corresponding bolt holes by multiple fastening bolts.

[0007] As a preferred embodiment of the above technical solution, a motor is fixedly installed inside the mounting frame, and multiple fan blades are fixedly installed at the output end of the motor.

[0008] As a preferred embodiment of the above technical solution, a protective net is fixedly installed on the side of the two mounting brackets away from the bottom of the backrest frame, and the surface of the protective net is provided with a number of openings for ventilation.

[0009] As a preferred embodiment of the above technical solution, the second heat dissipation mechanism includes a first heat dissipation hole and a second heat dissipation hole. Ventilation grooves are provided inside the backrest frame, and a plurality of first heat dissipation holes and second heat dissipation holes are provided on the rear surface and side surface of the backrest frame, respectively. The first heat dissipation holes and the second heat dissipation holes are all connected to the ventilation grooves.

[0010] As a preferred embodiment of the above technical solution, the skeleton body is made of a lightweight alloy.

[0011] This utility model has at least the following beneficial effects: Through the combined design of the first and second heat dissipation mechanisms, the motor and fan blades of the first heat dissipation mechanism can actively push airflow, while the ventilation slots and heat dissipation holes of the second heat dissipation mechanism can guide the airflow in a three-dimensional circulation. The two work together to quickly dissipate heat and moisture inside the frame and the back, effectively solving the problems of poor breathability and heat accumulation in traditional backrest frames, and significantly improving the dryness of the seat.

[0012] This utility model also has the following beneficial effects: The frame is made of lightweight alloy material, which greatly reduces the overall weight while ensuring structural stability, making it easy to be adapted and installed with various types of seats and reducing the overall load on the seats.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] Reference Figure 1-4 A backrest frame with ventilation and heat dissipation function includes a frame body 1. The frame body 1 includes two backrest frames 2, an upper crossbeam 3 and a lower crossbeam 4. The upper crossbeam 3 is fixedly installed at the top between the two backrest frames 2, and the lower crossbeam 4 is fixedly installed at the bottom between the two backrest frames 2. A first heat dissipation mechanism 5 for ventilation and heat dissipation inside the frame body 1 is fixedly installed at the bottom of each of the two backrest frames 2. A second heat dissipation mechanism 6 for ventilation and heat dissipation inside the frame body 1 is also provided on the surface of the two backrest frames 2.

[0018] Furthermore, the first heat dissipation mechanism 5 includes a mounting groove 7. The bottom of the backrest frame 2 is provided with a mounting groove 7, and the surface of the mounting groove 7 is provided with bolt holes 8. The bottom of the mounting groove 7 is provided with a mounting bracket 10. The mounting bracket 10 is fixedly installed on the surface of the corresponding bolt holes 8 by multiple fastening bolts 9. Specifically, the mounting bracket 10 is installed inside the mounting groove 7 by aligning the fastening bolts 9 with the bolt holes 8.

[0019] Furthermore, a motor 11 is fixedly installed inside the mounting bracket 10, and multiple fan blades 12 are fixedly installed at the output end of the motor 11. Specifically, the motor 11 is a low-power silent DC motor 11, which can flexibly adjust the speed according to the usage scenario to avoid noise interference during operation; the fan blades 12 are made of ABS engineering plastic in one piece, and the blades have an arc-shaped airflow guide design, which can maximize the air pushing efficiency and ensure that the airflow can quickly spread upward along the backrest frame 2.

[0020] Furthermore, a protective net 13 is fixedly installed on the side of the two mounting brackets 10 away from the bottom of the backrest frame 2, and the surface of the protective net 13 has several openings for ventilation. Specifically, the protective net 13 is woven from fine-diameter galvanized steel wire, and the size of the mesh takes into account both protection and ventilation needs. It can effectively prevent foreign objects from entering the mounting bracket 10 and damaging the motor 11 and fan blades 12, without significantly obstructing the airflow, ensuring that the heat dissipation airflow can smoothly pass through the protective net 13 into the backrest frame 2.

[0021] Furthermore, the second heat dissipation mechanism 6 includes a first heat dissipation hole 14 and a second heat dissipation hole 15. Ventilation grooves 16 are provided inside the backrest frame 2, and a plurality of first heat dissipation holes 14 and second heat dissipation holes 15 are provided on the rear surface and side surface of the backrest frame 2, respectively. The first heat dissipation holes 14 and second heat dissipation holes 15 are connected to the ventilation grooves 16. Specifically, the ventilation grooves 16 are elongated and penetrate the interior of the backrest frame 2 to ensure that there is sufficient space for airflow inside. The first heat dissipation holes 14 are circular holes and are arranged in a matrix along the rear surface of the backrest frame 2 to facilitate the dissipation of heat to the external environment. The second heat dissipation holes 15 are elongated holes and are evenly distributed along the side surface of the backrest frame 2 to help guide the side airflow and avoid local heat accumulation.

[0022] Furthermore, the frame body 1 is made of lightweight alloy, specifically, aerospace-grade aluminum alloy, which is processed by extrusion molding. This material has a density much lower than traditional steel, which can significantly reduce the overall weight. At the same time, it has excellent thermal conductivity, which can quickly conduct heat from the surface of the backrest frame 2, reducing the heat retention time on the frame body 1, thus balancing lightweight and heat dissipation performance.

[0023] In summary: Regarding active cooling, the low-power, silent DC motor 11 within the mounting bracket 10, paired with arc-shaped guide fan blades 12, actively propels airflow along the backrest frame 2 and allows for speed adjustment to suit different usage needs, while avoiding noise interference and ensuring users enjoy cooling in a quiet environment. The addition of the protective mesh 13 ensures the safety of the motor 11 and fan blades 12 without affecting airflow, forming a closed loop for active cooling. Regarding passive ventilation, the ventilation slots 16 inside the backrest frame 2 run vertically, working in conjunction with the rear matrix-style circular first heat dissipation holes 14 and the evenly distributed elongated second heat dissipation holes 15 on the sides to create a three-dimensional ventilation path, allowing heat to be quickly expelled from multiple angles, effectively preventing localized heat accumulation. Furthermore, the use of aerospace-grade aluminum alloy not only significantly reduces the overall weight of the frame and improves installation and usage flexibility, but its excellent thermal conductivity also accelerates heat conduction and reduces heat retention on the frame surface.
