Abstract
Description
Technical Field
[0001] The utility model relates to the field of motorcycles and motorcycle parts, and in particular to a gear display switch assembly and a motorcycle. Background Art
[0002] Existing gear display switches mainly adopt a two-stage injection molding structure: the gear display contacts are first assembled with the injection-molded position frame, then welded with the lead wires, and then injection-molded as a whole; because the shell and the gear display contacts and lead wires cannot be integrated, the thermal deformation coefficients are different. During the operation of the engine, the working environment oil temperature changes continuously, and there are oil leakage and contact loosening and withdrawal phenomena. The potential risk factor is relatively large and directly affects the driving experience.
[0003] Therefore, there is a need for a gear display switch assembly and a motorcycle that can optimize the structure of the gear display contact connection, avoid loosening and oil leakage of the gear display contact, and improve product quality. Utility Model Content

The annular groove I and the annular groove II have the characteristics of stable connection, which is not only beneficial for processing and production, but also facilitates the convenient assembly of the gear display contact on the housing.
[0009] Furthermore, it also includes a position frame, the position frame has a functional hole, the gear display contact passes through the functional hole to limit the position frame on the housing; the gear display contact has a blocking head, the housing has a limiting support, and the gear display contact limits the position frame on the limiting support of the housing through the blocking head;
[0010] There are a plurality of functional holes, and the plurality of functional holes are distributed on the position frame in a predetermined shape. In this embodiment, the plurality of functional holes are distributed in a ring shape on the periphery of the position frame. The position frame is disc-shaped and is limited by a plurality of gear display contacts on a limit support formed at the front end of the housing.
[0011] There are a plurality of gear display contacts, the number of the functional holes is the same as the number of the gear display contacts, and the functional holes and the gear display contacts are connected in a one-to-one correspondence.
[0012] Furthermore, the shell also has a limiting hole that circumferentially surrounds the blocking head; and the front end face of the shell is flush with the front end face of the gear display contact, that is, the shell also forms a limiting protection for the blocking head of the gear display contact, preventing the gear display contact from detaching, shifting or loosening, thereby improving product quality.
[0013] Furthermore, the device further includes a lead wire connected to the connection end, and the connection between the lead wire and the connection end is wrapped with a sealing filler to improve wiring reliability and sealing. It should be understood that the number of lead wires and gear indicator contacts is the same, and the lead wires and gear indicator contacts are connected in a one-to-one relationship.
