[0066] In some embodiments, reference Figure 1-8 The first rotating member 300 also includes a first anti-rotation portion 330 protruding from the outer periphery of the main body 310, and the game track also includes an anti-rotation member 500, an elastic reset member 600 and a linkage assembly 700; the anti-rotation member 500 is movably arranged on the track acceleration section 100, and the anti-rotation member 500 has an anti-rotation end 510 that can move between a stop position and an unlocking position, and the anti-rotation end 510 can cooperate with the first anti-rotation portion 330 at the stop position, and the anti-rotation end 510 releases the anti-rotation cooperation with the first anti-rotation portion 330 at the unlocking position; the elastic reset member 600 is connected to the anti-rotation member 500 and the track acceleration section 100, and is used to make The anti-rotation member 500 has a tendency to tend to the stuck position; the linkage assembly 700 has a first linkage end 731 and a trigger end 721 extending into the track acceleration section 100, the anti-rotation member 500 also has a second linkage end 520, the first linkage end 731 cooperates with the second linkage end 520, and the trigger end 721 can reciprocate between the trigger position and the return position; wherein, the trigger end 721 extends into the track acceleration section 100 in the return position and the anti-rotation end 510 stops at the stuck position, and the trigger end 721 is configured to be pushed to the trigger position by the racing car passing through the track acceleration section 100 to trigger the anti-rotation end 510 to move to the unlocking position.

[0067] Since the first rotating member 300 also includes a first stop portion 330 protruding from the outer periphery of the main body 310, the stop member 500 has a stop end 510 that can move between a locking position and an unlocking position, and the stop end 510 can cooperate with the first stop portion 330 in the locking position, and the stop end 510 releases the stop cooperation with the first stop portion 330 in the unlocking position; thereby, the first rotating member 300 can be controlled to limit rotation, so as to suppress the volute spring 400 from releasing energy, thereby preventing it from rotating; then, by setting the stop member 500, the elastic reset member 600 and the linkage assembly 700, when the trigger end 721 is pushed to the trigger position by the racing car passing through the track acceleration section 100, the stop end 510 is triggered to move to the unlocking position, and then the first rotating member 300 rotates, and the racing car passing through the track acceleration section 100 is pushed by the swing arm portion 320, thereby realizing non-electric acceleration of the racing car.

[0068] In some embodiments, reference Figure 1-8 The anti-rotation member 500 is a swing rod rotatably arranged on the track acceleration section 100, one end of the swing rod forms the second linkage end 520, and the other end of the swing rod forms the anti-rotation end 510, which has a simple structure and low cost. Among them, the elastic reset member 600 can be selected as a tension spring. One end of the elastic reset member 600 can be connected to the anti-rotation member 500, and the other end can be connected to the base 210 or the track acceleration section 100, thereby realizing the elastic reset control of the anti-rotation member 500 through tension.

[0069] refer to Figure 1-8 In some embodiments, the linkage assembly 700 includes a linkage shaft 710, a first swinging member 720 and a second swinging member 730. The linkage shaft 710 is rotatably arranged on the track acceleration section 100. The first swinging member 720 is fixed to one end of the linkage shaft 710 and is formed with a trigger end 721. The first swinging member 720 can drive the trigger end 721 to swing back and forth between the trigger position and the return position around the linkage shaft 710. The second swinging member 730 is fixed to the other end of the linkage shaft 710 and is formed with a first linkage end 731. The second swinging member 730 can drive the first linkage end 731 to swing back and forth around the linkage shaft 710, so as to linkage trigger the second linkage end 520 to drive the stop end 510 to move back and forth between the stop position and the unlocking position. The structure is simple, the cost is low, and mechanical linkage trigger control can be realized. Specifically, the linkage shaft 710 can be rotatably installed on the back of the track acceleration section 100, and an avoidance hole is opened on the road surface of the track acceleration section 100, and the avoidance hole allows the trigger end 721 of the first swinging member 720 to pass through and penetrate into the track of the track acceleration section 100.

[0070] In some embodiments, reference Figure 1-8The bearing assembly 200 further includes a first shaft 220, a first rotating disk 230, a fixing head 240, a first one-way anti-rotation tooth 250, and a spring 260. The first shaft 220 is coaxial with the first axis X, and one end of the first shaft 220 is fixed to the base 210; the first rotating disk 230 is rotatably inserted into the first shaft 220, and the first rotating disk 230 has a first connecting portion 231 connected to the second end 420, and the first rotating disk 230 also has a second one-way anti-rotation tooth portion 232; the fixing head 240 is fixed to the other end of the first shaft 220; the first one-way anti-rotation tooth 250 and the fixing head 240 are connected to each other. A non-rotatable sliding plug-in fit, with the first one-way stop tooth 250 clamped between the fixed head 240 and the second one-way stop tooth portion 232, and the second one-way stop tooth portion 232 being able to perform one-way stop engagement with the first one-way stop tooth 250; a spring 260 is clamped between the fixed head 240 and the first one-way stop tooth 250 to drive the first one-way stop tooth 250 to perform one-way stop engagement with the second one-way stop tooth portion 232.

[0071] Through the above design, the first rotating disk 230 has the function of one-way rotation. When the first rotating member 300 is restricted from rotating, for example, by the anti-rotation member 500 of the above embodiment, the second end 420 of the spiral spring 400 can be driven to perform a winding and energy storage movement by rotating the first rotating disk 230. After the winding is completed, the first rotating disk 230 is released. Since the second one-way anti-rotation tooth portion 232 is engaged with the first one-way anti-rotation tooth 250, energy cannot be released, and energy storage is achieved.

[0072] In order to facilitate the energy storage of the spiral spring 400, refer to Figure 1-8 In some embodiments, the support assembly 200 further includes a hand crank assembly 270, which can cooperate with the first turntable 230 to prevent rotation in one direction, so as to drive the first turntable 230 to rotate by hand cranking the hand crank assembly 270, so that the first turntable 230 drives the second end 420 of the spiral spring 400 to perform energy storage and winding motion.

[0073] refer to Figure 1-8In some embodiments, the first rotating disk 230 further has a third one-way anti-rotation tooth portion 233, and the hand crank assembly 270 includes a hand crank chassis 271, a fourth one-way anti-rotation member 272, a hand crank top cover 273, and a hand crank lever 274. The hand crank chassis 271 is rotatably coaxially inserted into the first shaft 220; the fourth one-way anti-rotation member 272 is disposed on the hand crank chassis 271, and the fourth one-way anti-rotation member 272 is one-way anti-rotationally matched with the third one-way anti-rotation tooth portion 233; the hand crank top cover 273 is fixedly connected to the hand crank chassis 271; and the hand crank lever 274 is fixedly connected to the hand crank top cover 273. The fourth one-way anti-rotation member 272 cooperates with the third one-way anti-rotation tooth portion 233 for one-way anti-rotation, so that the hand-cranked chassis 271 can only drive the first turntable 230 to make a movement to cause the second end 420 of the spiral spring 400 to store energy and wind. When the hand-cranked chassis 271 rotates in the opposite direction, it will not drive the first turntable 230 to rotate.

[0074] Specifically, in some embodiments, reference Figure 1-8 The fourth one-way anti-rotation member 272 includes a compression spring 2721 and a pressure head 2722. The compression spring 2721 is disposed in the hand-cranked chassis 271; the pressure head 2722 is slidably disposed in the hand-cranked chassis 271, and the pressure head 2722 can be displaced in a first direction perpendicular to the first shaft 220. One end of the compression spring 2721 along the first direction abuts against the pressure head 2722, and the other end of the compression spring 2721 abuts against the hand-cranked chassis 271, so that the pressure head 2722 and the third one-way anti-rotation tooth portion 233 are in one-way anti-rotation cooperation, and then the one-way rotation is stopped by the one-way anti-rotation cooperation between the pressure head 2722 and the third one-way anti-rotation tooth portion 233.

[0075] More specifically, see Figure 1-8 In some embodiments, the first one-way anti-rotation tooth 250 and the second one-way anti-rotation tooth portion 232 are one-way ratchet structures. The one-way ratchet structure adopts an existing structure that can be used to cooperate with other structures to achieve one-way rotation locking.

[0076] Further, refer to Figure 1-8 In some embodiments, the third one-way anti-rotation tooth portion 233 is a one-way external ratchet structure. In the direction of the first axis X, part of the structure of the hand-cranked chassis 271 extends into the interval gap formed between the fixed head 240 and the first turntable 230, thereby limiting the position of the hand-cranked chassis 271 in the direction of the first axis X, preventing the hand-cranked chassis 271 from falling off, and forming a reliable and stable structure.

[0077] Furthermore, refer to Figure 1-8 The track acceleration section 100 may be an arc-shaped groove track, and the track of the arc-shaped groove track overlaps with the motion track of the swing arm part 320 as much as possible, thereby extending the pushing acceleration distance of the swing arm part 320 on the racing car and obtaining a higher acceleration.

[0078] Of course, in order to avoid mutual interference, the inner side wall of the arc-shaped groove track can be eliminated while retaining the outer side wall of the arc-shaped groove track.

[0079] Further, refer to Figure 1-8 The first rotating member 300 may have two swing arms 320, and the angle between the two swing arms 320 is 180 degrees. There may also be two corresponding first stoppers 330 protruding from the outer periphery of the main body 310, and the two first stoppers 330 are respectively located on opposite sides of the outer periphery of the main body 310, so that the first rotating member 300 can be stopped by the stopper 500 once every 180 degrees of rotation, thereby accelerating and pushing the racing car passing through the track acceleration section 100.

[0080] Furthermore, the embodiment of the present application also provides a track racing car toy, which includes a racing car (not shown in the figure) and a game track as described in any of the above embodiments. The racing car can be a non-powered car without a power source, which relies on the rotation of the first rotating member 300 of the game track and pushes the racing car through the track acceleration section 100 with the help of the swing arm part 320, so as to achieve non-electric acceleration of the racing car and improve playability.

[0081] In some embodiments, reference Figure 1-8 The track racing car toy also includes a track uphill section (not shown in the figure), a track downhill section (not shown in the figure), and a track rotation section. The track uphill section is located downstream of the track acceleration section 100; the track downhill section is located downstream of the track uphill section, and the track downhill section and the track uphill section are connected by forming an overhead leap section through mutual spacing; the downstream of the track downhill section of the track rotation section is connected to the upstream of the track acceleration section 100 through the track rotation section, so that the car has ups and downs and leaps, which improves playability. In some embodiments, it can also be other types of tracks, such as an 8-shaped closed loop track.

[0082] Note that the above are only preferred embodiments of the present invention and the technical principles used. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention.
