Description

Technical Field

[0001] This utility model relates to the field of motorcycle parts technology, specifically to a swing arm connection structure for a motorcycle windshield lifting device. Background Technology

[0002] As an important protective component, the motorcycle windshield effectively blocks airflow, dust, and debris, improving riding comfort and safety. To adapt to different riding scenarios and user needs, liftable windshield devices are widely used. The rationality of its swing arm connection structure directly affects the ease of disassembly and assembly, the range of height adjustment, and production costs.

[0003] In existing motorcycle windshield lifter arm connection structures, the active swing arm and active shaft, and the driven swing arm and driven shaft, often adopt an integrated fixed or complex nested connection method, such as the motorcycle windshield lifter disclosed in application number CN2025209492081. This type of structure has significant drawbacks: First, it is cumbersome to disassemble and assemble; when adjusting the windshield lifting angle to suit different usage scenarios, multiple components need to be disassembled, making operation inconvenient. Second, the structure is complex, usually requiring additional connecting parts such as the driven shaft, which not only increases the number of parts but also increases the difficulty of production and assembly. Third, the cost is high; the increase in parts and assembly difficulty directly leads to higher production costs, which is detrimental to market promotion.

[0004] Therefore, there is an urgent need for a swing arm connection structure for motorcycle windshield lifting devices that is easy to assemble and disassemble, has a simplified structure, is cost-controllable, and can flexibly adjust the lifting angle to adapt to different usage scenarios, so as to solve the above-mentioned problems existing in the prior art.

[0009] Furthermore, the outer ring of the shaft cover is provided with a gripping slope, and the surface of the gripping slope is provided with a plurality of strip-shaped grooves at intervals.

[0010] The beneficial effects of this utility model are: First, it improves the ease of assembly and disassembly. By setting a first screw hole at the end of the drive shaft and a matching connecting hole at the end of the drive arm, and cooperating with the second screw hole on the rotating bushing of the mounting bracket and the first fixing hole of the driven arm, the drive arm and drive shaft, as well as the driven arm and mounting bracket, can be quickly assembled and disassembled with bolts without disassembling too many related parts, which provides convenience for subsequent maintenance and component replacement.

[0011] Second, the overall product structure is simplified. This structure abandons the traditional connection method between the driven swing arm and the driven shaft in the existing technology, and directly achieves the assembly and positioning of the driven swing arm through the rotating bushing on the mounting bracket. This reduces the number of unnecessary connecting parts, lowers the structural complexity, and also helps to improve the stability and reliability of the device during operation.

[0012] Third, it reduces production and usage costs. The simplified structure not only reduces the number of parts to be manufactured, lowering material and assembly costs in the production process, but also saves on labor costs during subsequent maintenance due to the increased ease of disassembly and assembly, further enhancing the product's economic efficiency and making it more suitable for market promotion and application.

[0013] Fourth, it enhances the adaptability to various usage scenarios. Based on the bolt-connected detachable structure, users can easily replace the active and driven swing arms of different lengths according to their needs for windshield lifting angle in different riding scenarios. This allows for flexible adjustment of the windshield lifting angle without modifying the main structure of the device, effectively improving the product's versatility and practicality, and better meeting diverse user needs.
