Technical Field

[0001] This utility model relates to a mechanical drive mechanism, specifically a gearbox push rod. Background Technology

[0002] Gearbox push rods are a type of push rod mechanism driven by an electric motor. However, current gearbox push rods have insufficient torque transmission in confined spaces and cannot achieve greater torque through the cooperation of the gearbox and lead screw. Utility Model Content

[0003] The purpose of this utility model is to provide a gearbox push rod, and the technical problem to be solved is: how to achieve high torque output in a small space by combining a gearbox and a lead screw with low current, that is, to achieve high torque output of a small motor under the condition of low current in a small space.

[0004] The gearbox push rod includes a motor, a worm gear, a first double gear, a second double gear, a third double gear, an output gear, a lead screw, and a push rod. The worm gear serves as the rotating shaft of the motor and meshes with the first double gear. The first double gear meshes with the third double gear through the second double gear. The third double gear meshes with the output gear. The lead screw is fitted onto the inner hole of the output gear, and the lead screw is assembled with the push rod. The first double gear has a tooth count Z of 10 / 25 and a module M of 0.5 / 0.5. The second double gear has a tooth count Z of 11 / 36 and a module M of 0.6 / 0.5. The third double gear has a tooth count Z of 10 / 28 and a module M of 0.8 / 0.6. The output gear has a tooth count Z of 34 and a module M of 0.8.

[0005] The gearbox push rod also has a housing, in which the worm gear, the first double gear, the second double gear, the third double gear, and the output gear are all arranged.

[0006] The transmission ratio of the entire gearbox push rod is 1:780.

[0007] The housing contains a stabilizing seat, which is designed with a stabilizing block and a base. The stabilizing block limits the movement of the worm gear, and the base supports and fixes the stabilizing block.

[0008] The beneficial effect of this utility model is that by driving three double gears with specific tooth count and module design through a worm gear, it is possible to achieve the output of a small motor with high torque under the conditions of small space and low current.

[0023] Please refer to Figures 1 to 3 The gearbox push rod in the figure mainly consists of a motor 1, a housing 9, a stabilizing seat 3, a first double gear 3, a second double gear 4, a third double gear 5, an output gear 6, a lead screw, and a push rod 8. This design achieves high torque output from a small motor 1 within a small space and under low current conditions, resulting in a transmission ratio of 1:780 for the entire gearbox push rod. In practical applications, the above components can be further optimized and redesigned as needed, or existing components can be used for equivalent replacement, or additional components can be added.

[0024] The motor 1 in the figure is a micro motor 1. Its specific model can be selected according to the function of the push rod 8. Existing micro motors 1 can be used as a reference.

[0025] The box 9 in the figure is a frame structure, which is designed with a base 91 and a top cover 92. The base 91 has an internal cavity and an open top, which makes it easy to place the worm gear, three double gears, output gear 6, and the bottom part of the lead screw 7 into the cavity. The top cover 92 is used to seal the base 91.

[0026] The stabilizing base 10 in the figure is designed with a stabilizing block 101 and a base 102. The stabilizing block 101 is used to abut against the worm gear 2 to limit the worm gear 2 and prevent or reduce its shaking. The stabilizing block 101 can be designed with additional features such as round holes and bearings, as long as it can limit and stabilize the worm gear 2. The base 102 in the figure extends upward from the bottom of the base 91 of the housing 9, which facilitates the installation of the stabilizing block 101 on the base 102. The specific shapes of the stabilizing block 101 and the base 102 in the figure can be selected according to factors such as the application environment.

[0027] The worm gear 2 in the figure adopts a conventional worm gear 2 structure, which can be directly used as the rotating shaft of motor 1 or installed on the rotating shaft. As long as motor 1 rotates, the worm gear 2 can also rotate.

[0028] The first double gear 3 in the figure consists of two gears connected in series. The number of teeth Z of these two gears is 10 / 25, and the module M is 0.5 / 0.5. As shown in the figure, the gear in the lower position drives the worm gear 2, and the gear in the upper position drives the second double gear 4. The first double gear 3 passes through the second double gear 4.

[0029] The second double gear 4 in the figure consists of two gears connected in series. The number of teeth Z of these two gears is 11 / 36, and the module M is 0.6 / 0.5. As shown in the figure, the gear in the lower position transmits power to the third double gear 5 to complete the transmission of the second double gear 4 through the third double gear 5.

[0030] The third double gear 5 in the figure consists of two gears connected in series. The number of teeth Z of these two gears is 10 / 28, and the module M is 0.8 / 0.6. As shown in the figure, the gear in the lower position drives the output tooth 6 to complete the meshing of the third double gear 5 with the output tooth 6.

[0031] The output tooth 6 in the figure is a conventional gear structure with a tooth count Z of 34 and a module M of 0.8. The bottom part of the lead screw 7 is fitted onto the inner hole of the output tooth 6.

[0032] The lead screw 7 and push rod 8 in the figure are existing parts and assembled in the existing manner.
