Description

Technical Field

[0001] The utility model belongs to the technical field of seat back heat dissipation, and in particular relates to an isolation support component for a seat back heat dissipation fan. Background Art

[0002] Currently, there is a lack of isolation support components for the fans installed on the seat back air bags. When the passenger leans back on the seat, the pressure behind the seat back causes the fan to move backward synchronously and collide with other components on the rear side, such as the shock absorbing device, causing abnormal noise, seriously affecting the riding experience. Moreover, the fan draws air through the ventilation belt on the front side of the seat back and then discharges it to the rear side. Therefore, the space behind the fan is limited, resulting in poor air outlet effect, affecting the heat dissipation effect of the seat. Utility Model Content

The left and right horizontal sections of the upper connecting rod are symmetrically welded with mounting plates, and the mounting plates are equipped with shock-absorbing equipment. The rod body of the fan isolation strut in contact with the air bag is a square structure with an open top, and the left and right ends of the rod body at the top of the fan isolation strut are bent backward and downward at an acute angle and then inwardly welded horizontally to the mounting plate, thereby forming an elastic support space for isolating the fan, thereby realizing the mutual isolation of the fan and the shock-absorbing equipment.

[0005] As a preferred embodiment of the above scheme, noise reduction and shock absorbing cotton is provided between the wind bag and the fan housing. Compared with the direct contact between the fan housing and the wind bag, the vibration noise generated when the fan is in operation is directly transmitted to the fan housing to produce abnormal noise. The noise reduction and shock absorbing cotton is provided between the fan housing and the wind bag. The fan operation noise can be effectively reduced, and the design structure is reasonable.

[0006] Further preferably, the left and right ends of the top of the fan isolation support rod are bent backward and downward at an angle of 20° to 60°, and the bending part has a smooth transition, the angle is reasonably designed, the smooth transition ensures elasticity, the design is reasonable, and the conception is ingenious.

[0007] Further preferably, the upper connecting rod and the lower connecting rod extend upward and backward as a whole along the backward tilting trend of the backrest backboard, which has a reasonable structure and avoids installation conflicts.

[0008] Further preferably, the left and right ends of the back panel lining are fixedly connected to the backrest frame by a horizontal connecting piece, and the back panel lining is connected at three places on the left, middle and right to form a triangular stable installation. The inner side of the backrest back panel is provided with an opening inclined upward, and the left and right sides of the lower connecting rod are provided with horizontal sections that hook the slot, so that the hook connection is convenient for assembly and disassembly.

[0009] Further preferably, the reinforcing connecting plate and the back plate lining are connected by gantry clip connection and screw fixing, which is firmly fixed and easy to install.

[0010] Further preferably, the horizontal connecting member as a whole is a "C"-shaped groove structure with its opening facing forward, the upper and lower side panels of the horizontal connecting member are provided with arc-shaped notches that match the contour of the backrest frame, the vertical plates are provided with mounting holes at intervals on the left and right, and are equipped with screws that pass through the inner side panels of the back panel lining and are inserted into the mounting holes. The design is reasonable to ensure that the installation position of the back panel lining is stable and to strengthen the connection with the backrest frame.

[0011] Further preferably, the back panel lining is symmetrically provided with installation platforms corresponding to the horizontal connecting members and the reinforcing connecting plates on the left, middle and right sides, so that they can be installed with screws after being fitted together, and the installation is convenient and quick, and the design is reasonable.

[0012] Beneficial effects of the utility model:

[0013] (1) Compared with the situation where the back pressure of the backrest causes the fan to move backward synchronously and collide with other components at the rear side, and the space behind the fan is limited, this solution adds a fan isolation strut to form an elastic support space to isolate the fan, thereby isolating the fan and the shock absorbing device from each other, thereby effectively avoiding the collision between the fan and the shock absorbing device and causing abnormal noise. The air outlet space at the rear side of the fan is sufficient to ensure good heat dissipation effect, effectively improve the passenger experience, and have a novel design concept.

[0014] (2) The rod body of the part where the fan isolation strut contacts the air bag is a square structure with an open top, and the rod bodies at the left and right ends of the top of the fan isolation strut are bent backward and downward at an acute angle and then welded inward and horizontally to the mounting plate, forming an acute-angled triangle stable support structure. When a passenger leans back on the seat, the backrest is pressed back through the triangular bends of the left and right ends of the top of the fan isolation strut to elastically support and buffer, effectively reduce deformation, and effectively reduce the foreign body feeling of the passenger when leaning against the seat surface, thereby preventing the fan isolation strut from protruding without elastic variables and causing the passenger to be stuck when leaning on the seat, effectively enhancing the passenger's riding comfort, with a reasonable design and ingenious design structure.

[0015] (3) The upper and lower ends of the reinforcing connecting plate are fixedly connected to the middle horizontal section of the upper connecting rod and the middle horizontal section of the lower connecting rod respectively. Compared with the seat backrest backboard and the backboard lining parts being connected and positioned with the seat frame respectively through upper and lower spaced steel wire connecting rods, the middle horizontal section of the upper connecting rod and the middle horizontal section of the lower connecting rod are fixedly connected through the reinforcing connecting plate, thereby strengthening the connection between the backrest backboard, the backboard lining parts and the backrest frame, ensuring smooth assembly and precise assembly position.

[0016] To sum up, it has the advantages of eliminating abnormal noise from fan collision, improving passenger experience, ensuring heat dissipation effect, triangular elastic stable support, ingenious design structure, and precise assembly position. BRIEF DESCRIPTION OF THE DRAWINGS
