Track module and toy car track

A toy car track, comprising a plurality of track modules;

• wherein the plurality of track modules are connected end to end in sequence;
• wherein each track module comprises a plurality of track units connected sequentially;
• wherein each track unit comprises a connecting portion and two track portions disposed on opposite sides of the connecting portion in a first direction;
• wherein the connecting portion is arranged with a protruding portion and defines a groove, and the protruding portion and the groove are disposed on opposite sides in a front-rear direction;
• for each adjacent two track units among the plurality of track units, the adjacent two track units are a front track unit and a rear track unit in the front-rear direction;
• a rotating part and a mating part are arranged between the protruding portion of the rear track unit and the groove of the front track unit, enabling the adjacent two track units to be swingably connected in a lateral direction;
• the first direction and the front-rear direction intersect each other on a horizontal lateral plane;
• the protruding portion and the groove are disposed in a middle part of the connecting portion;
• a front end of the connecting portion is arranged with two first abutting surfaces located on opposite sides of the protruding portion in the first direction;
• a rear end of the connecting portion is arranged with two second abutting surfaces corresponding to the first abutting surfaces;
• in a case where the track module is in a straight shape, the two first abutting surfaces of the rear track unit and the two second abutting surfaces of the front track unit are arranged spaced apart;
• the adjacent two track units are capable of being swung laterally relative to each other to a bent state on one side;
• in the bent state, one of the two first abutting surfaces located on a bent side of the rear track unit abuts against the one of the two second abutting surfaces located on the bent side of the front track unit, for limiting a swing amplitude of the adjacent two track units;
• wherein the rotating part is a through hole defined on the protruding portion and penetrating through in the first direction;
• the mating part is a crossbeam provided in the groove, and the crossbeam of the front track unit is capable of penetrating through the through hole of the rear track unit;
• in a case where the track module is in the straight shape, a shortest distance between a front wall of the through hole of the rear track unit and the crossbeam of the front track unit is greater than or equal to a maximum distance between each first abutting surface of the rear track unit and a corresponding second abutting surface of the front track unit.

• wherein the connecting portion is arranged with a protruding portion and defines a groove, and the protruding portion and the groove are disposed on opposite sides in a front-rear direction;
• for each adjacent two track units among the plurality of track units, the adjacent two track units are a front track unit and a rear track unit in the front-rear direction;
• a rotating part and a mating part are arranged between the protruding portion of the rear track unit and the groove of the front track unit, enabling the adjacent two track units to be swingably connected in a lateral direction;
• the first direction and the front-rear direction intersect each other on a horizontal lateral plane;
• the protruding portion and the groove are disposed in a middle part of the connecting portion;
• a front end of the connecting portion is arranged with two first abutting surfaces located on opposite sides of the protruding portion in the first direction;
• a rear end of the connecting portion is arranged with two second abutting surfaces corresponding to the first abutting surfaces;
• in a case where the track module is in a straight shape, the two first abutting surfaces of the rear track unit and the two second abutting surfaces of the front track unit are arranged spaced apart;
• the adjacent two track units are capable of being swung laterally relative to each other to a bent state on one side;
• in the bent state, one of the two first abutting surfaces located on a bent side of the rear track unit abuts against the one of the two second abutting surfaces located on the bent side of the front track unit, for limiting a swing amplitude of the adjacent two track units;
• wherein the rotating part is an arc-shaped protrusion arranged on the protruding portion;
• the arc-shaped protrusion extends from one of the two first abutting surfaces to the other of the two first abutting surfaces around a peripheral direction of the arc-shaped protrusion;
• the mating part is an insertion hole defined on a bottom wall of the groove;
• the insertion hole extends from one of the two second abutting surfaces to the other of the two second abutting surfaces around the peripheral direction of the arc-shaped protrusion;
• the arc-shaped protrusion of the rear track unit is capable of being rotatably inserted into the insertion hole of the front track unit, enabling each first abutting surface and a corresponding second abutting surface located on a same side to abut against each other;
• wherein the arc-shaped protrusion is arranged with at least one engaging block;
• the at least one engaging block of the rear track unit is capable of being detachably engaged in the insertion hole of the front track unit, and the at least one engaging block of the rear track unit is slidable within the insertion hole of the front track unit along the peripheral direction of the arc-shaped protrusion of the rear track unit.
