DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model embodiment provides an adjustable racing car model steering transmission structure, such as Figure 1-Figure 7 As shown, an adjustable racing car model steering transmission structure includes a racing car model base 1 and a mounting base 2; the top of the racing car model base 1 is provided with a mounting base 2, the top of the mounting base 2 is provided with a servo motor 3, a side of the mounting base 2 is provided with a controller 4, and the front end of the servo motor 3 is provided with a differential 8; an auxiliary structure 9 is provided on one side of the top of the racing car model base 1, and a steering structure 5 is provided at the front end of the differential 8, front wheels 6 are provided on both sides of one end of the racing car model base 1, and a battery 7 is provided at the bottom end of the racing car model base 1. In a further preferred embodiment of the utility model, as Figure 1-Figure 7 As shown: the steering structure 5 includes a toothed plate 501, a gear 502, a limit sleeve 503, a connecting block 504, a fixing block 505, a connecting frame 506, and a connecting rod 507. The toothed plate 501 is arranged at one end of the top of the racing model base 1. The top of the toothed plate 501 is provided with a gear 502. One end of the gear 502 is connected to one end of the differential 8. A limit sleeve 503 is arranged on the outer side of one end of the gear 502. The fixing block 505 is arranged on both sides of one end of the top of the racing model base 1. The top of the fixing block 505 is movable. A connecting block 504 is connected, one end of the connecting block 504 is connected to the front wheel 6, connecting rods 507 are hinged inside the two sides of the toothed plate 501, and a connecting frame 506 is hinged on the outer side of the top of the connecting rod 507, one end of the connecting frame 506 is connected to one side of one end of the connecting block 504, a plurality of teeth are arranged on the top of the toothed plate 501, the toothed plate 501 is meshed with the gear 502, the inner diameter of the limiting sleeve 503 is larger than the outer diameter of one end of the gear 502, and the limiting sleeve 503 and one end of the gear 502 form a movable connection.

[0024] Specifically, when the racing car model base 1 needs to turn, the direction of rotation of the servo motor 3 is controlled according to the steering requirement. When the servo motor 3 rotates, it engages with the tooth plate 501, thereby driving the tooth plate 501 to move to one side. When the tooth plate 501 moves to one side, it pushes the connecting frame 506 to move to one side through the connecting rod 507. When the connecting frame 506 is pushed, it pushes the connecting block 504. Since one end of the connecting frame 506 is only a little fixed to one side of one end of the connecting block 504, and the bottom end of the connecting block 504 is hinged to the fixed block 505, when the connecting block 504 is pushed, it will drive the front wheel 6 to make a tilted rotation to one side to complete the steering, making it more convenient to adjust the steering of the racing car model base 1.

[0025] In a further preferred embodiment of the present invention, Figure 1-Figure 7 As shown: the auxiliary structure 9 includes a guide rail 901, a movable groove 902 and a movable bead 903. The guide rail 901 is arranged at one end of the top of the racing car model base 1. A tooth plate 501 is arranged inside the guide rail 901.
