Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of starters, in particular to a lightweight starter armature structure. Background Art
[0002] The starter, also known as the motor, converts the electrical energy of the battery into mechanical energy, drives the engine flywheel to rotate and starts the engine. The drive mode is unidirectional drive. The starter consists of three parts: a DC motor, a one-way clutch with gears, and a control switch. At the same time, according to the different control methods, it can be divided into mechanical control and electromagnetic control. According to the engagement method, it can be divided into three types: forced engagement, inertia engagement and electromagnetic engagement.
[0003] The car starter can convert the battery's electrical energy into mechanical energy, drive the engine flywheel to rotate and start the engine. At present, the technology of car starters is very mature, but with the improvement of people's requirements, the development trend of car starters tends to be lightweight. The existing lightweight engines start from their internal structure, while the outer shell of the engine is still bulky. Although some lightweight engine shells are light in weight, the structural stability of the shell is reduced, and it is difficult to effectively protect the internal structure of the engine.
[0004] To this end, we propose a lightweight starter armature structure. Utility Model Content
[0005] The utility model mainly solves the above technical problems and provides a lightweight starter armature structure.
[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a lightweight starter armature structure, comprising a main housing, a rear cover is provided on the rear side of the main housing, an intermediate housing is provided on the front side of the main housing, a transmission mechanism is provided in the intermediate housing, a plurality of groups of lugs are provided on the outer side of the intermediate housing, a front housing with a conical structure is fixedly installed on the front side of the intermediate housing, a planetary shaft is provided in the main housing, and the planetary shaft passes through the intermediate housing and the front housing and extends forward horizontally;
[0007] The main shell includes a solid layer, which is arranged in the innermost layer. The outer surface fixing sleeve of the solid layer is provided with an elastic mesh layer, and the outer surface fixing sleeve of the elastic mesh layer is provided with a reinforced outer layer. By arranging the elastic mesh layer in the middle layer, the elastic mesh layer protects the solid layer, thereby protecting the components inside the main shell. Since the elastic mesh layer is an elastic grid structure, the overall weight of the main shell is greatly reduced.
[0008] Preferably, a plurality of through grooves are formed through the outer surface of the reinforced outer layer, and the plurality of through grooves are evenly arranged on the reinforced outer layer.
[0009] Preferably, a rolling ball is movably installed inside the through groove. When the outside of the main shell is collided, the collision force will act on the rolling ball, the rolling ball will be concave inward and transmit the force to the elastic mesh layer, which will buffer the external collision force through the elastic mesh layer.
[0010] Preferably, the structures of the rear cover, the intermediate shell and the front shell are the same as the main shell structure, and the internal components of the starter are protected by the main shell, the intermediate shell and the front shell.
[0011] Preferably, a first connecting block and a second connecting block are fixedly mounted on the main housing, respectively, and a control mechanism is arranged between the first connecting block and the second connecting block. The electromagnetic switch assembly, the armature assembly, etc. in the main housing are controlled by the arranged control mechanism, and the control mechanism controls the transmission assembly in the intermediate housing at the same time.
[0012] Beneficial Effects
[0013] The utility model provides a lightweight starter armature structure, which has the following beneficial effects:
[0014] (1) This lightweight starter armature structure has an elastic mesh layer arranged in the middle layer so that the elastic mesh layer protects the solid layer, thereby protecting the components in the main housing. Since the elastic mesh layer is an elastic grid structure, the overall weight of the main housing is greatly reduced, thereby achieving the effect of making the starter lightweight.
[0015] (2) In this lightweight starter armature structure, when the outside of the main housing is hit, the collision force will act on the ball, which will sink inward and transmit the force to the elastic mesh layer. The elastic mesh layer will buffer the external collision force, thereby further protecting the components inside the main housing. The main housing, intermediate housing and front housing are provided to protect the internal components of the starter, buffer the collision force accidentally received by the starter, and achieve the effect of efficiently protecting the internal components of the starter.
