Description

Technical Field

[0001] The utility model relates to the technical field of seat fans, and particularly relates to an assembly structure between a housing and a fan blade of a seat fan. Background Art

[0002] Currently, the assembly between the housing and the fan blade of a seat fan mostly adopts the traditional method of fixing with glue. However, over time, this method has revealed many drawbacks, especially in terms of traditional production and quality stability.

[0003] First of all, the method of fixing with glue significantly increases the production time cost, thereby reducing the overall production efficiency. Whenever the fan blade and the housing are fixed with glue, it is necessary to wait for the glue to dry completely before proceeding to the next production step. This waiting time not only consumes a large amount of time but also may cause the equipment on the production line to be idle, unable to fully utilize its production capacity.

[0004] Secondly, the addition of the glue application process greatly increases the complexity of the automated production line. On an automated production line, each operation needs to be precisely controlled to ensure the stability of production efficiency and product quality. However, the introduction of the glue application process requires additional equipment and operations on the production line to ensure the uniform application and accurate control of the glue, which undoubtedly increases the complexity and maintenance cost of the automated production line.

[0005] In addition, the method of fixing with glue also faces the problem of being unable to strictly guarantee the amount of glue applied. Since the application and drying process of the glue are affected by various factors, such as temperature, humidity, and manual operation, it is very difficult to ensure that the amount of glue applied each time is exactly the same. This will result in inconsistent adhesion forces between the fan blade and the housing, thereby affecting the stability and service life of the product.

[0006] Finally, the nature of the glue itself is also likely to cause component failures. Over time, the glue may age and fail, resulting in the loosening or even detachment of the fixation between the fan blade and the housing. This will not only affect the normal use of the product but also pose a threat to the safety of the user. Summary of the Utility Model

[0007] The technical problem to be solved by the utility model is to provide an assembly structure between the housing and the fan blade of a seat fan in view of the above deficiencies existing in the assembly of the existing seat fan and the fan blade by using the method of fixing with glue. This design not only simplifies the production process, improves the production efficiency, but also ensures the stability of product quality, providing a more convenient and efficient solution for automated production.

[0008] The technical problem to be solved by the utility model can be achieved through the following technical solutions:

[0009] An assembly structure between the housing and the fan blade of a seat fan, comprising a fan blade and a housing. A housing mounting hole is provided at the center of the fan blade. The housing is cylindrical. It is characterized in that at least one reverse buckle hole is provided on the hole wall of the housing mounting hole; at least one elastic reverse buckle is provided on the outer surface of the housing arm of the housing. During assembly, the housing is inserted into the housing mounting hole, and the reverse buckle is buckled into the reverse buckle hole.

[0010] In a preferred embodiment of the present invention, a plurality of the reverse buckle holes are arranged on the hole wall of the housing mounting hole; the elastic reverse buckles are also arranged on the outer surface of the housing arm of the housing.

[0011] Due to the adoption of the above technical solution, the present invention is provided with an elastic reverse buckle on the housing and a reverse buckle hole on the hole wall of the housing mounting hole of the fan blade. During assembly, the reverse buckle on the housing is embedded into the corresponding reverse buckle hole, so that the housing and the fan blade are tightly combined, which not only greatly improves the stability of the connection between the housing and the fan blade, but also makes the entire assembly process of the housing and the fan blade simpler and faster.

[0012] Adopting this direct fixing method, first of all, the production process is significantly simplified. There is no need for additional glue rubbing process and the time to wait for the glue to dry. The entire assembly process can be completed in one go, greatly improving the production efficiency. At the same time, since no glue is used, the problem of glue aging and failure is also avoided, thus ensuring the stability of product quality. In addition, this design also provides a more convenient and efficient solution for automation. On the automated production line, the machine can precisely control each assembly step to ensure that each reverse buckle and reverse buckle hole can be precisely matched. This high-precision control not only improves the assembly efficiency, but also reduces the errors that may be brought by manual operation, further improving the product quality.
