Description

Technical Field

[0001] The utility model relates to the technical field of vehicle seats, and more particularly, to a cold and hot ventilation system for a vehicle seat. Background Technique

[0002] As an important means of transportation, automobiles have increasingly entered the homes of residents. The vehicle seat is the main contact part between the driver, passengers and the vehicle. With the development of modern society, people's requirements for vehicle seats are getting higher and higher, and more emphasis is placed on comfort. Therefore, the cold and hot ventilation device for vehicle seats has emerged as the times require.

[0003] After retrieval, a cold and hot ventilation system for a vehicle seat is disclosed in a Chinese patent with the publication number CN219601013U, which includes a blower. The blower includes a volute with an air inlet and an air outlet. A rotating impeller is arranged in the volute, and a graphene heating sheet is arranged in the volute. External air enters the volute through the air inlet under the action of the impeller. The graphene heating sheet generates heat when energized. The external air becomes hot air through the graphene heating sheet in the volute and is blown out towards the air outlet. The volute includes an upper shell and a lower shell. The graphene heating sheet is fixed in the upper shell and / or the lower shell by pasting or fasteners; alternatively, an air outlet member is arranged at the air outlet of the volute, and the graphene heating sheet is arranged in the air outlet member.

[0029] The technical solution provided by the present utility model is as follows: As Figures 1-4 shown, in this embodiment, a cold and hot ventilation system for an automobile seat includes an installation shell 1 and a blower 2. The blower 2 is provided with an air outlet 3 and an air inlet 4. A wind outlet member 5 is connected to the outlet of the air outlet 3. A connecting hose 6 is fixedly connected to the outlet end of the wind outlet member 5. A swing mechanism is arranged inside the installation shell 1. The swing mechanism includes a double-shaft motor 7 fixedly connected to the front middle part of the bottom of the inner cavity of the installation shell 1.

Air outlet holes 13 are evenly formed through the top of the air outlet box 12. By rotating the double-shaft motor 7, the rotating disks 8 are driven to rotate, so that the connecting rods 9 deflect, and the air outlet box 12 moves back and forth, thus facilitating uniform air outlet.

[0030] As Figure 2 shown, the outlet end of the connecting hose 6 penetrates and extends to the bottom of the inner cavity of the installation shell 1, and the outlet end of the connecting hose 6 is fixedly connected to the inlet end at the middle part of the bottom of the air outlet box 12.

[0031] As Figure 2 shown, the blower 2 is fixedly connected to the rear part of the bottom of the installation shell 1 by screws. The other end of the connecting rod 9 is rotatably connected to the front part of the left and right sides of the air outlet box 12, which is convenient for the connecting rod 9 to drive the air outlet box 12 to move when deflecting.

[0032] As Figure 2 shown, the input ends of the blower 2 and the double-shaft motor 7 are electrically connected to the output end of an external power supply through wires, which is convenient for power supply.

[0033] As Figure 4 shown, a protection mechanism is arranged at the bottom of the blower 2. The protection mechanism includes installation boxes 14 symmetrically and fixedly connected to the outer side walls of the blower 2. A pull rod 15 penetrates and slidably connects to the upper part of the outer side wall of the installation box 14. A pull plate 16 is fixedly connected to one end of the pull rod 15 located outside the installation box 14. A connecting plate 17 is fixedly connected to one end of the pull rod 15 located inside the installation box 14. A return spring 18 is fixedly connected to the outer side wall of the connecting plate 17, and the return spring 18 is sleeved on the outer side of the pull rod 15. A clamping block 19 is fixedly connected to the bottom of the connecting plate 17. A filter screen 20 is connected to the bottom of the blower 2. L-shaped rods 21 are symmetrically and fixedly connected to the outer side wall of the filter screen 20. A triangular block 22 is fixedly connected to the top of the L-shaped rod 21. Through the setting of the protection mechanism, it is convenient to filter the incoming air, avoid dust from entering the inside of the blower 2, and at the same time facilitate the disassembly and assembly of the filter screen 20.

[0034] As Figure 4As shown, the connecting plate 17 is slidably connected to the inside of the mounting box 14, and the outer sidewall of the connecting plate 17 is in contact with the inner sidewall of the mounting box 14 to limit the position of the connecting plate 17, facilitating the stable movement of the connecting plate 17.

[0035] As Figure 4 shown, the return spring 18 is located inside the mounting box 14, and the other end of the return spring 18 is fixedly connected to the inner sidewall of the mounting box 14. The bottom of the clamping block 19 is provided with an inclined surface, facilitating the inclined surface of the triangular block 22 to squeeze the clamping block 19 and causing the clamping block 19 to move.

[0036] The present utility model provides a cold and hot ventilation system for an automotive seat, and the specific working principle is as follows: Install the device on the seat. During use, first install the filter screen 20. Embed the triangular block 22 into the mounting box 14, and squeeze the filter screen 20 upward, causing the L-shaped rod 21 to drive the triangular block 22 to move upward, squeezing the clamping block 19, thereby causing the two connecting plates 17 to move away from each other and squeezing the return spring 18. When the triangular block 22 is located above the clamping block 19, through the reset of the return spring 18, the connecting plate 17 drives the clamping block 19 to reset, clamping the triangular block 22, installing the filter screen 20, and filtering the air entering the blower 2 through the setting of the filter screen 20;

[0037] During ventilation, start the bi-axial motor 7. When the bi-axial motor 7 rotates, it drives the rotating disc 8 to rotate, causing the connecting rod 9 to deflect. Through the cooperation of the sliding rod 10 and the slider 11, when the connecting rod 9 deflects, it drives the air outlet box 12 to reciprocate back and forth, thereby causing the air outlet 13 to reciprocate back and forth, changing the ventilation position and increasing the ventilation range. During heating, use the graphene heating sheet inside the air outlet component 5 to heat the air, so that the blown air is hot air to heat the seat;

[0038] After long-term use, it is necessary to clean the filter screen 20 to prevent dust from blocking the filter screen 20 and affecting ventilation. During disassembly, just pull the pull plate 16 to drive the pull rod 15 to move, thereby causing the two connecting plates 17 to move away from each other, separating the clamping block 19 from the triangular block 22, releasing the clamping of the triangular block 22, and thus disassembling the filter screen 20 for easy cleaning.

[0039] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
