The fixed block piece 1″ is fixed on the front end of the main vehicle frame 10, and has a wall body 11′ of a C-shaped configuration, and two engaging holes 12 formed in two terminal ends of the wall body 11′. Each adaptor block piece 4 has a curved wall body 41, an adaptor engaging hole 42 and an adaptor insert plug 43. The curved wall body 41 has first and second wall segments 411, 412 extending transverse to each other. The adaptor engaging hole 42 is formed in the first wall segment 411 and configured to be engaged with a polygonal insert plug 22 of the second plug block piece 2′ (or a polygonal insert plug 22 of the first plug block piece 2 in the previous embodiment). The adaptor insert plug 43 projects from the second wall segment 412 and is configured to be engaged in an engaging hole 12 of the socket block piece 1. Specifically, the adaptor engaging hole 42 has a cross-section of a regular polygonal shape to allow insertion and frictional engagement of the polygonal insert plug 22 of the second plug block piece 2′ (or the first plug block piece 2). The extending direction of the adaptor insert plug 43 is transverse to the inserting direction of the adaptor engaging hole 42. The adaptor insert plug 43 has a cross-section of a regular polygonal shape to be inserted into and frictionally engaged with the engaging hole 12 of the socket block piece 1. The adaptor insert plug 43 has a configuration similar to that of the polygonal insert plug 22. Alternatively, the extending direction of the adaptor insert plug 43 may be not transverse to the inserting direction of the adaptor engaging hole 42. Still alternatively, the adaptor insert plug 43 may have a cross-section of a circular shape and may be similar to the circular insert plug 23 in configuration. The adaptor engaging holes 42 of the adaptor block pieces 4 are disposed inboard of the C-shaped wall body 11′ of the fixed block piece 1″ and respectively aligned with the engaging holes 12 of the fixed block piece 1″. Two of the second plug block pieces 2′ are disposed to interconnect each adaptor block piece and the fixed block piece 1″. Specifically, the polygonal and circular insert plugs 22, 23 of the second plug block piece 2′ are respectively engaged in the aligned adaptor engaging hole 42 and the engaging hole 12 so as to allow rotation of the adaptor block piece 4 relative to the fixed block piece 1″. One of the socket block pieces 1 erects and has upper and lower engaging holes 12 respectively engaged with the adaptor insert plugs 43 of the adaptor block pieces 4, and a middle engaging hole 12 aligned with an axial hole (201a) in the front wheel 201. One of the second plug block pieces 2′ is disposed to interconnect the socket block piece 1 and the front wheel 201 to have the polygonal insert plug 22 engaged with the middle engaging hole 12 of the socket block piece 1, and the circular insert plug 23 engaged with the axial hole (201a) of the front wheel 201 to allow rotation of the front wheel 201 relative to the socket block piece 1 for rolling on a support surface (not shown). The other one of the socket block pieces 1 is placed horizontally above the fixed block piece 1″, and has an engaging hole 12 aligned with the engaging hole 12 of the fixed block piece 1″. The polygonal insert plug 22 of one second plug block piece 2′ is engaged in the engaging hole 12 of the socket block piece 1. The rotating shaft 5 has a cross-section of a polygonal shape, such as a regular hexagonal shape, and is made from a copper material. The rotating shaft 5 is configured to be inserted into the tubular holes 24 of the three aligned second plug block pieces 2′ so as to operatively drive rotation of the second plug block pieces 2′ with the rotating shaft 5 about the rotating axis. Thus, when the horizontal socket block piece 1 above the fixed block piece 1″ is rotated relative to the rotating shaft 5, the adaptor block pieces 4 are driven to rotate about and relative to the rotating shaft 5 so as to turn the front wheel 201 and the upright socket block piece 1 about the rotating shaft 5 to perform turning of the front wheel 201.
The control unit 30 has an elongated socket block piece 1′ and two second plug block pieces 2′. The socket wall body 11 of the elongated socket block piece 1′ is in the form of an elongated plate which extends in an elongated direction and is longer than the socket block piece 1 of the first embodiment, and has a plurality of the engaging holes 12 which are spaced apart from each other along the elongated direction. Two of the engaging holes 12 at two ends thereof are respectively aligned with the rear engaging holes 12 of the horizontal socket block pieces 1 of the turning mechanisms 20. The polygonal insert plugs 22 of the two second plug block pieces 2′ are respectively engaged in the rear engaging holes 12 of the horizontal socket block pieces 1 of the turning mechanisms 20, and the circular insert plugs 23 thereof are respectively engaged in the end engaging holes 12 of the elongated socket block piece 1′ so as to allow rotation of the elongated socket block piece 1′″ relative to the horizontal socket block pieces 1 of the turning mechanisms 20. Thus, as shown in
The rear wheels 40 are disposed at two sides of a rear end of the main vehicle frame 10. The motors 50 are disposed on the main vehicle frame 10 to respectively drive the rear wheels 40 to move forwards the toy vehicle.
As illustrated, with the engaging holes 12 of a regular polygonal shape and the polygonal insert plugs 22 configured to be inserted into the engaging holes 12, rotation of the plug block pieces relative to the socket block pieces is allowed and can keep a predetermined angle of the plug block pieces relative to the socket block pieces for playing and using the toy building block set with more variety.
