Abstract

A double-sided toy car capable of vertical turning within a sealed track, including: a car body (1); a front wheel (2); and a rear wheel (3) including a pair of upper driving wheels (32) and a pair of lower driving wheels (31)), a maximum distance between an upper end and a lower end of the front wheel (2) is less than or equal to a maximum distance between the upper and lower driving wheels after the rear wheel (3) is maximally elastically contracted, the maximum distance is less than or equal to a height of a sealed track (4), therefore ensuring that the double-sided car can smoothly pass through a vertical turning segment, however a maximum distance between the upper and lower driving wheels before the rear wheel (3) is elastically contracted is greater than the height of the sealed track (4), therefore achieving a crawling on the vertical track.

Claims

1. A double-sided toy car capable of vertical turning within a sealed track comprising:

a car body (1);

a front wheel (2) arranged at a front portion of the car body (1), protruding above and below the car body (1) and acting as a driven wheel; and

a rear wheel (3) arranged at a rear portion of the car body (1) and comprising a pair of upper driving wheels (32) protruding above the car body (1) and a pair of lower driving wheels (31) protruding below the car body (1), wherein the rear wheel (3) is designed as a wheel having an ability of elastically deformable contraction, a maximum distance between an upper end and a lower end of the front wheel (2) is less than or equal to a maximum distance between the upper and lower driving wheels after the rear wheel (3) is maximally elastically contracted, the maximum distance between the upper and lower driving wheels after the rear wheel (3) is maximally elastically contracted is less than or equal to a height of a sealed track (4) fitted with the toy car, however a maximum distance between the upper and lower driving wheels before the rear wheel (3) is elastically contracted is greater than the height of the sealed track (4).

2. The double-sided toy car according to claim 1, wherein a wheel surface of each of the upper driving wheels (32) and/or the lower driving wheels (31) of the rear wheel (3) is provided with an elastic saw tooth (30), so as to achieve elastic contraction of the rear wheel.

3. The double-sided toy car according to claim 1, wherein the elastic saw tooth (30) is configured to be a plurality of circular elastic convex columns spaced from each other and encircling a soft ring, so as to form a jagged wheel ring, and the wheel ring is fitted over the wheel surface of each of the upper driving wheels (32) and/or the lower driving wheels (31).

4. The double-sided toy car according to claim 1, wherein the front wheel (2) is configured to be one driven wheel having a diameter larger than a height of the car body (1) and protruding above and below the car body (1), the driven wheel is rotatably connected to a middle position of the front portion of the car body (1) through a rotating shaft, and the diameter of the driven wheel is less than or equal to the maximum distance between the upper and lower driving wheels after the rear wheel (3) is maximally elastically contracted.

5. The double-sided toy car according to claim 1, wherein the front wheel (2) is configured to be a pair of driven wheels each having a diameter larger than a height of the car body (1) and protruding above and below the car body (1), the pair of driven wheels are rotatably connected to two side positions of the front portion of the car body (1) through a rotating shaft, and the diameter of each the driven wheel is less than or equal to the maximum distance between the upper and lower driving wheels (3) after the rear wheel is maximally elastically contracted.

6. The double-sided toy car according to claim 1, wherein the front wheel (2) comprises one upper driven wheel protruding above the car body (1) and a pair of lower driven wheels protruding below the car body (1), the upper driven wheel is connected to a middle position of the front portion of the car body (1) adjacent to an upper end through a rotating shaft, the pair of lower driven wheels is connected to two side positions of the front portion of the car body (1) adjacent to a lower end through a rotating shaft, and a maximum perpendicular distance between the upper and lower driven wheels is less than or equal to the maximum distance between the upper and lower driving wheels after the rear wheel (3) is maximally elastically contracted.

7. The double-sided toy car according to claim 1, wherein the front wheel (2) comprises a pair of upper driven wheels protruding above the car body (1) and one lower driven wheel protruding below the car body (1), the pair of upper driven wheels is connected to two side positions of the front portion of the car body (1) adjacent to an upper end through a rotating shaft, a pair of lower driven wheels is connected to a middle position of the front portion of the car body (1) adjacent to a lower end through a rotating shaft, and a maximum perpendicular distance between the upper and lower driven wheels is less than or equal to the maximum distance between the upper and lower driving wheels after the rear wheel (3) is maximally elastically contracted.

8. The double-sided toy car according to claim 1, wherein the front wheel (2) comprises a pair of upper driven wheels (22) protruding above the car body (1) and a pair of lower driven wheels (21) protruding below the car body, the upper driven wheels (22) are connected to two side positions of the front portion of the car body (1) adjacent to an upper end through a rotating shaft, the lower driven wheels (21) are connected to two side positons of the front portion of the car body (1) adjacent to an lower end through a rotating shaft, and a maximum perpendicular distance between the upper and lower driven wheels is less than or equal to the maximum distance between the upper and lower driving wheels after the rear wheel (3) is maximally elastically contracted.

9. The double-sided toy car according to claim 1, wherein a rotating shaft core of the upper driving wheels (32) and a rotating shaft core of the lower driving wheels (31) are located in a same perpendicular cross section perpendicular to the car body (1).

10. The double-sided toy car according to claim 1, wherein the upper driving wheels (32) and the lower driving wheels (31) are driven by one transmission structure, thus achieving that the upper driving wheels (32) and the lower driving wheels (31) rotate in different directions and at a same speed.

11. The double-sided toy car according to claim 2, wherein a rotating shaft core of the upper driving wheels (32) and a rotating shaft core of the lower driving wheels (31) are located in a same perpendicular cross section perpendicular to the car body (1).
