In the figure: 1. the device comprises a shell, 2, a fixed block, 3, a fixed hole, 4, a motor, 5, a driving gear, 6, a transmission gear, 7, a sleeve, 8, a threaded hole, 9, a fixed sleeve, 10, a push rod structure, 11, a rod body, 12, threads, 13, a connector, 14, a push plate, 15, an oil bin, 16, an oil seal port, 17 and a piston.
Detailed Description
The utility model is described in further detail below with reference to the drawings and the specific examples.
As shown in fig. 1 to 3, a push rod device suitable for an electric handle of an automobile is provided, wherein a housing 1, a fixing block 2, a fixing hole 3, a motor 4, a driving gear 5, a transmission gear 6, a sleeve 7, a threaded hole 8, a fixing sleeve 9 and a push rod structure 10 are arranged at the top end of the housing 1, the fixing block 2 is arranged at the left end and the right end of the fixing block 2 in a mounting mode, the motor 4 is fixed at the left part in the housing 1, the driving gear 5 is arranged at the rear driving end of the motor 4, the transmission gear 6 is meshed with the driving gear 5, the sleeve 7 is axially fixed at the middle part of the front end of the transmission gear 6, the threaded hole 8 is axially arranged at the middle part of the sleeve 7, the fixing sleeve 9 is fixed at the right part in the housing 1, the fixing sleeve 9 is rotationally connected at the side end of the sleeve 7, and the push rod structure 10 is arranged at the sleeve 7.
The push rod structure 10 comprises a rod body 11, threads 12, a connector 13, a push plate 14, an oil bin 15, an oil seal port 16 and a piston 17, wherein the threads 12 are formed in the side end of the rod body 11, the threads 12 are connected in the threaded holes 8, the connector 13 is rotatably connected to the front end of the rod body 11, the push plate 14 is hinged to the connector 13, the oil bin 15 is fixed to the rod body 11, the oil seal port 16 is formed in the side end of the oil bin 15, and the piston 17 is mounted at the rear end of the oil bin 15.
