AI Technical Summary
The installation of the worm gear in existing train models can only be completed after the bogie is installed, which leads to the problem that the worm gear is prone to falling off during disassembly.
The bogie adopts a modular mounting structure. By setting a worm gear mounting slot and a snap-fit module on the motor mounting base, the worm gear mounting slot has a hollow structure and a snap-fit socket on both sides. The snap-fit module can rotate around the worm gear mounting slot, so as to realize the independent installation and removal of the worm gear.
The modular installation of the worm gear is achieved, the bogie can be plugged in and unplugged, and the worm gear is not easy to fall off during disassembly. The bogie has a large angle of swing and pitch capability.

[0005] The utility model adopts the following technical scheme:
[0006] A wheel bogie mounting structure of a train model, comprising a motor mounting seat and a bogie gear box, the motor mounting seat has a worm mounting groove 1, the worm mounting groove 1 has a gear insertion port 11 in the center, the two sides of the worm mounting groove 1 have a hollow structure as a clamping socket 12 of the bogie, the two sides of the worm mounting groove 1 form an arc-shaped outer wall surface, the arc-shaped outer wall surface has a clamping tenon 3 for clamping, the top of the bogie gear box is inserted into the clamping socket 12 and matched with the clamping tenon 3 to realize clamping, the two sides of the clamping module 2 have a clamping groove of the clamping tenon 3 for containing, and the clamping module 2 can rotate by a certain angle around the worm mounting groove 1.
[0007] The clamping module 2 is composed of two clamping plates, the inner surface of the clamping plate is arc-shaped, and the side wall of the clamping plate is hollow as a clamping groove for containing the clamping tenon 3.
[0008] The size of the clamping groove is greater than that of the clamping tenon 3, so as to satisfy the swing range of a certain angle in the horizontal and vertical directions in the clamping state.
[0009] The clamping module 2 is erected on the upper end face of the bogie gear box, the upper end face has a protrusion 4, the lower bottom face of the slot body of the worm mounting slot 1 is a plane, and the protrusion 4 prevents the upper end face of the bogie gear box from being attached to the lower bottom face of the slot body of the worm mounting slot 1.
[0010] The bottom of the motor mounting seat has a mounting slot matched with the shape of the bogie gear box, and the two sides of the mounting slot are fan-shaped.
[0011] The utility model has the following beneficial effects:
[0012] 1. The installation of the worm is completely independent of the bogie, and the worm can still be completely installed and fixed after the bogie is disassembled, so that the modular installation of the bogie is realized.
[0013] 2. The transverse size of the clamping groove is much larger than the width of the clamping tongue, the bogie can swing left and right by a large angle on the horizontal plane, the longitudinal height of the clamping groove is also larger than the longitudinal size of the clamping tongue, and in addition, the protrusion between the upper end face of the gear box and the motor mounting surface can prevent the two faces from being attached, when the track has an upward slope or a downward slope, the bogie can also easily realize a certain degree of pitching compared with the vehicle body because the two faces are in point contact.
