Description

Technical Field

[0001] This utility model relates to the field of children's toys, specifically to a mechanism that enables rapid switching between omnidirectional wheel mode and directional wheel mode through mechanical transmission. Background Technology

[0002] There are many types and styles of toy cars on the market. Generally, toy cars have the function of moving forward and backward. However, when a toy car is hit while moving forward, it will be unable to continue moving forward. Some toy cars have universal steering wheels, which allow the toy car to turn freely. However, these existing toy cars have the disadvantages of limited functionality and low playability. Utility Model Content

[0003] The purpose of this invention is to solve the aforementioned problems in the existing technology and to provide a mechanism that enables rapid switching between omnidirectional wheel mode and directional wheel mode through mechanical transmission.

[0004] According to the present invention, a toy car steering wheel mechanism capable of switching between omnidirectional and straight-line modes includes a steering wheel and a switching mechanism. The steering wheel's axle bracket has a locking groove. The switching mechanism includes a switching key, a swing arm, and a compression spring. The switching key is slidably mounted on the car body, and an inclined push block is provided inside the switching key, with a rounded end face at the distal end. The swing arm is pivotally connected to the car body, with a locking pin at the first end of the swing arm engaging with the locking groove, and a cylinder fixedly mounted at the second end of the swing arm. The compression spring is positioned between the first end of the swing arm and the car body base. The cylindrical surface of the cylinder and the rounded end face form an interference fit.

[0005] When the switch key slides to the first limit position, the inclined push block abuts against the cylindrical drive arm to rotate clockwise around the pivot, causing the locking pin to disengage from the locking groove. The compression spring is compressed and stores energy, and the cylinder and the rounded end face are interference-fitted. When the switch key slides to the second limit position, the rounded end face separates from the cylinder, the compression spring recovers its deformation and drives the drive arm to rotate counterclockwise, and the locking pin is inserted into the locking groove.

[0006] As a further embodiment of this invention, the locking groove is a U-shaped groove that passes through the wheel axle bracket.

[0007] As a further embodiment of this invention, the top of the switch key extends to the surface of the vehicle body shell.

[0008] As a further embodiment of this invention, the inclination angle α of the inclined push block is 120°-150°.

[0009] As a further embodiment of this utility model, the steering wheel is a double-wheel universal wheel assembly or a spherical universal wheel.

[0010] Work process:

[0011] 1. Directional Mode → Omnidirectional Mode:

[0012] (1) Push the switch key along direction S1 to the first extreme position;

[0013] (2) The inclined surface of the inclined push block contacts the cylindrical surface of the cylinder and applies a component force;

[0014] (3) Rotate the arm clockwise;

[0015] (4) The locking pin is completely disengaged from the locking groove, and the cylinder is inserted into the interference area of ​​the rounded end face.

[0016] 2. Universal Mode → Directional Mode:

[0017] (1) Push the switch key along direction S2 to the second extreme position;

[0018] (2) The rounded end face separates from the cylindrical surface of the cylinder;

[0019] (3) The compressed spring releases the stored energy, driving the swing arm to rotate counterclockwise;

[0020] (4) The locking pin slides into the locking groove.

[0021] The advantages of this utility model are: 1. The mechanical switching structure is low in cost, simple to operate, and highly reliable, making it suitable for children's use. The pure mechanical structure avoids electronic component failures. 2. The toy car can be selected to use either a straight-line driving mode or a free-turning driving mode, which is highly playable, can attract children's attention, and exercise children's hands-on and thinking abilities.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] It should be noted that, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0032] like Figures 1-3 As shown, the toy car steering wheel mechanism that can switch between omnidirectional and straight-line modes includes a steering wheel 1 and a switching mechanism 2. The steering wheel 1 has a locking groove 12 on its wheel axle bracket 11. The switching mechanism 2 includes a switching key 21, a swing arm 22, and a compression spring 23.

The compression spring 23 is compressed and stored energy, and the cylinder 222 is interference-fitted with the rounded end face 2110. When the switch key 21 slides to the second limit position, the rounded end face 2110 separates from the cylinder 222, the compression spring 23 recovers its deformation, driving the swing arm 22 to rotate counterclockwise, and the locking pin 221 is inserted into the locking groove 12.

[0034] In a preferred embodiment, the locking groove 12 is a U-shaped groove that passes through the wheel axle bracket 11; the top of the switching key 21 extends to the outer surface of the vehicle body 100; the tilt angle α of the inclined push block 211 is 135°; and the steering wheel 1 is a double-wheel universal wheel assembly.

[0035] Work process:

[0036] 1. Directional Mode → Omnidirectional Mode:

[0037] (1) Push the switch key 21 along direction S1 to the first extreme position;

[0038] (2) The inclined surface of the inclined push block 211 contacts the cylindrical surface of the cylinder 222 and applies a component force;

[0039] (3) The swing arm 22 rotates clockwise;

[0040] (4) The locking pin 221 is completely disengaged from the locking groove 12, and the cylinder 222 is inserted into the interference area of ​​the rounded end face 2110.

[0041] 2. Universal Mode → Directional Mode:

[0042] (1) Push the switch key 21 along direction S2 to the second extreme position;

[0043] (2) The rounded end face 2110 separates from the cylindrical surface of the cylinder 222;

[0044] (3) The compression spring 23 releases the stored energy, driving the swing arm 22 to rotate counterclockwise;

[0045] (4) Locking pin 221 slides into locking groove 12.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
