Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive seat technology, and in particular to a fixing structure for an automotive seat fan. Background Technology
[0002] Currently, ventilation or cooling fans installed in car seats mainly use screws or traditional snap-fit fixing structures. While screw fixing offers high connection strength, the installation process is cumbersome, requires tools, and is inefficient in mass production and routine maintenance, making disassembly and assembly inconvenient. Traditional snap-fit fixing structures typically use rigid plastic clips, lacking self-adjusting capabilities during installation, which can easily lead to improper installation, difficulty in locking, or insecure installation due to tolerances.
[0003] In actual vehicle operation, the seat will be subjected to continuous vibration and impact. The existing fixing methods have obvious drawbacks: screw fixing cannot meet the needs of rapid assembly; traditional buckle structure is prone to loosening, abnormal noise or even falling off under long-term vibration, lacking effective buffering and stabilizing measures, which directly affects the operating stability and service life of the fan.
[0004] Therefore, there is an urgent need for a car seat fan fixing structure that can take into account quick disassembly and assembly, reliable connection, and good cushioning and shock absorption performance. Utility Model Content
[0005] To address the aforementioned problems in the prior art, this utility model provides a fixing structure for a car seat fan, which enables quick installation and removal of the fan, while effectively absorbing and buffering vibrations during fan operation to ensure the firmness and stability of the connection.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0007] A fixing structure for an automotive seat fan includes a housing, inside which is a sliding shaft that can slide up and down. The bottom of the sliding shaft is connected to a chassis via a connecting shaft. A spring is sleeved on the sliding shaft, and the spring provides an elastic force to reset the sliding shaft. The chassis is circumferentially provided with a plurality of radially elastically deformable spring pieces, and the end of each spring piece is provided with a locking block for engaging.
[0008] Preferably, the fan body has a mounting slot, and the housing is installed inside the mounting slot.
[0009] Preferably, the top of the slide shaft extends out to form a head shaft.
[0010] Preferably, one end of the spring abuts against the internal structure of the housing, and the other end abuts against the head shaft.
[0011] Preferably, the outer shell is a cylinder that is thicker at the top and thinner at the bottom.
[0012] By adopting the above technical solution, the beneficial effects of this utility model compared with the prior art are:
[0013] 1. The present invention provides a fixing structure for a car seat fan, which can be quickly installed and disassembled: through a downward operation, the spring clips automatically retract and expand to achieve a snap-fit, requiring no tools, greatly improving the efficiency of installation and disassembly, and is suitable for large-scale production and maintenance.
[0014] 2. The fixing structure of the car seat fan of this utility model is firm and reliable: after the spring is expanded outward, the end of the locking block and the lower edge of the hole form a firm mechanical lock, which effectively prevents the fan from loosening under vibration and impact.
[0015] 3. The fixing structure of the car seat fan of this utility model has excellent buffering and shock absorption performance: the built-in spring can absorb and buffer the vibration and impact force from the axial and radial directions during the operation of the fan, avoiding the vibration from being directly transmitted to the seat structure, thus improving the smooth operation and service life of the fan.
[0016] 4. The fixing structure of the car seat fan of this utility model is self-adjustable: the cooperation of spring and elastic sheet makes the structure have a certain fault tolerance for installation tolerance, ensuring that a stable connection can be maintained under different working conditions.

The utility model provides a fixing structure for an automotive seat fan, including a fan body 1, a mounting groove 2, a housing 3, a sliding shaft 4, a head shaft 5, a spring 6, a connecting shaft 7, a chassis 8, spring pieces 9, and a locking block 10. The fan body 1 has a mounting groove 2, and the housing 3 is installed inside the mounting groove 2. The housing 3 is a cylinder that is thicker at the top and thinner at the bottom. A sliding shaft 4 that can slide up and down is provided inside the housing 3. The bottom of the sliding shaft 4 is connected to a chassis 8 via a connecting shaft 7. A spring 6 is fitted onto the sliding shaft 4. One end of the spring 6 abuts against the internal structure of the housing 3, and the other end abuts against the head shaft 5. The spring 6 provides an elastic force to reset the sliding shaft 4. The head shaft 5 extends from the top of the sliding shaft 4. Multiple radially elastically deformable spring pieces 9 are arranged circumferentially on the chassis 8, and each spring piece 9 has a locking block 10 at its end for engagement.
[0032] The following will refer to Figures 1 to 8 The working principle of this utility model will be explained.
[0033] When installing a car seat fan, first, precisely insert the outer casing 3 into the mounting slot 2, forming a stable mounting base between the outer casing 3 and the seat. Then, the operator aligns the fan body 1 with the installation position and presses down on the fan body 1 and the head shaft 5. During this pressing process, the sliding shaft 4 inside the outer casing 3 is pushed downwards, simultaneously compressing the connected spring 6 and storing elastic potential energy. As the sliding shaft 4 moves downwards, its bottom connecting shaft 7 compresses the chassis 8 downwards as well. At this time, multiple spring pieces 9 located around the chassis 8 are forced together, gradually moving inwards, allowing it to smoothly enter the mounting hole. Once the fan 1 is fully pressed into the preset installation depth, the lower end of the spring piece 9 extends beyond the edge of the hole. Under the restoring force of the spring 6 and the guiding action of the chassis 8, the spring piece 9 naturally expands outwards. The expanded spring piece 9 reliably engages with the lower edge of the hole via the locking block 10, thus securing the fan 1 firmly.
[0034] After the snap-fit action is completed, the sliding shaft 4 gradually returns to its original position under the elastic force of the spring 6, and the head shaft 5 and the internal structure of the outer casing 3 also return to their initial state, forming a stable installation state. At this time, the fan 1 is firmly fixed to the seat structure, and quick installation can be achieved without the need for additional screws or tools.
[0035] During the operation of fan 1, vibration and impact are inevitably generated due to high-speed rotation or vehicle driving environment. At this time, the spring 6 set in the housing 3 can provide a buffering effect in the radial and axial directions, effectively absorbing and dispersing part of the impact load, preventing vibration from being directly transmitted between the fan body 1 and the seat structure, thereby extending the overall service life and improving the working stability. At the same time, the cooperation between the chassis 8 and the connecting shaft 7 ensures the self-adjustment capability of the locking structure. Even under repeated vibration and impact, the locking block 10 and the hole remain tightly engaged, ensuring that the fan body 1 will not loosen or shift.
[0036] When the fan needs to be removed, simply press the clip 10 and the head shaft 5 from under or to the side of the seat to disengage them from the edge of the hole, and then lift the fan upwards. The operation is equally simple.
[0037] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
