DETAILED DESCRIPTION

[0033] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0034] Example:

[0035] like Figure 1 、 Figure 2 and Figure 3 The digital starter for a track bicycle shown in the figure comprises a support frame 1, and an air tank 2, an electrical control module 3 and a pneumatic gripper 4 arranged on the support frame 1;

[0036] The air outlet end of the air storage tank 2 is connected to the air inlet end of the electrical control module 3 through the first air pipe 5, and the air outlet end of the electrical control module 3 is connected to the pneumatic clamp 4 through the second air pipe 6. When the pneumatic clamp 4 is clamped, it clamps the rear wheel of the bicycle before departure.

[0037] In this embodiment, before a competition or training, the digital starter is placed on the bicycle track, and the rear wheel of the bicycle is placed between the two jaws of the pneumatic gripper 4. The electrical control module 3 controls the pneumatic gripper 4 to inflate so that its two jaws clamp the rear wheel of the bicycle. When the countdown ends and the competition begins, the electrical control module 3 controls the pneumatic gripper 4 to deflate, and the two jaws instantly release the rear wheel of the bicycle.

[0038] like Figure 1 、 Figure 2 and Figure 3 As shown, the upper front end of the support frame 1 is also provided with a V-shaped groove 7 for limiting the vertical rod of the bicycle seat. Before the bicycle sets off, the outer wall of the vertical rod of the seat is placed in the V-shaped groove 7.

[0039] In this embodiment, the bicycle seat vertical rod is limited by the V-shaped groove 7 so that the outer contour of the bicycle rear wheel is just located between the two clamping jaws of the pneumatic clamp 4.

[0040] like Figure 1 、 Figure 2 and Figure 3As shown, the electrical control module 3 includes a solenoid valve 301, a single joint 302 and a wireless communication module;

[0041] The air inlet end of the single-joint component 302 is connected to the air outlet end of the air storage tank 2 via the first air pipe 5, the air outlet end of the single-joint component 302 is connected to the air inlet end of the solenoid valve 301 via the third pipeline 23, and the air outlet end of the solenoid valve 301 is connected to the pneumatic gripper 4 via the second air pipe 6;

[0042] The wireless communication module is used to receive control signals from a remote host computer, and the control signal controls the on and off of the solenoid valve 301, and the on and off of the solenoid valve 301 controls the clamping or loosening of the pneumatic gripper 4. The solenoid valve 301 and the wireless communication module are both powered by a power module installed on the support frame 1.

[0043] In this embodiment, at the initial moment, when the outer contour of the bicycle's rear wheel is located between the two jaws of the pneumatic gripper 4, the main control computer sends a signal to the solenoid valve 301 via the wireless communication module. This energizes the solenoid valve 301, causing the air tank 2 to supply air to the pneumatic gripper 4, causing the two jaws to clamp the outer contour of the bicycle's rear wheel. One millisecond before the countdown ends, the main control computer sends a signal to the solenoid valve 301 via the wireless communication module, de-energizing the solenoid valve 301. The pneumatic gripper 4 deflates the air, and the two jaws instantly release the outer contour of the bicycle's rear wheel.

[0044] like Figure 1 、 Figure 2 and Figure 3 As shown, the gas storage tank 2 is connected to the first gas pipe 5 via a quick-connect connector;

[0045] A U-shaped card plate 8 with a downward opening is provided on the side wall of the gas storage tank 2. The two sides of the U-shaped card plate 8 are connected to the outer wall of the gas storage tank 2 through connecting plates 9. A threaded sleeve 25 is also installed on the end surface close to the gas storage tank 2. The vertical plates on both sides of the U-shaped card plate 8 are provided with a first screw through hole 10 that is concentric with the axis of the threaded sleeve 25.

[0046] like Figure 1 、 Figure 2 and Figure 3 As shown, a slot 11 for limiting the two sides of the U-shaped card plate 8 is provided on the crossbeam on the rear side of the support frame 1;

[0047] A second screw through hole 12 is also provided on the cross beam on the rear side of the support frame 1, and a placement platform 13 for placing the bottom end of the gas tank 2 is also provided on the rear side of the support frame 1. When the gas tank 2 is installed, the U-shaped clamping plate 8 is clamped on the cross beam on the rear side of the support frame 1, and the limit screw 14 passes through the first screw through hole 10 and the second screw through hole 12 and is threadedly connected to the threaded sleeve 25.

[0048] In this embodiment, the quick-connect connector includes a female quick-connect connector installed at the outlet end of the gas tank and a male quick-connect connector installed at one end of the first air pipe 5. When the gas tank 2 is underpressured, the quick-connect connector is removed from the first air pipe 5 by plugging and unplugging the quick-connect connector. The gas tank 2 can be removed by removing the stop screw 14. When installing a new gas tank 2, the U-shaped clamping plate 8 and the slot 11 allow for quick positioning of the gas tank 2, which is quickly locked by the stop screw 14. The gas tank 2 can then be replaced by plugging the quick-connect connector, making replacement simple and highly stable. In this embodiment, a handle is provided at one end of the stop screw 14 for easy turning.

[0049] like Figure 1 and Figure 4 As shown, the bottom end of the support frame 1 is provided with a universal wheel 15, and the bottom ends of the left and right sides of the support frame 1 are both provided with sliding support leg assemblies;

[0050] When the sliding support leg assembly is pushed out, the universal wheel 15 is separated from the ground; when the sliding support leg assembly is retracted, the universal wheel 15 is in contact with the ground.

[0051] In this embodiment, the universal wheel 15 is provided to facilitate the portable movement of the digital starter. During the movement of the digital starter, the sliding support leg assembly is in a retracted state. When the digital starter moves to a predetermined position, the sliding support leg assembly is pushed out, so that the universal wheel 15 is separated from the ground, thereby preventing the displacement of the starter from affecting the performance of the athletes before the game.

[0052] like Figure 1 and Figure 4 As shown, the sliding support leg assembly includes a sliding sleeve 16 installed at the bottom end of the front and rear sides of the support frame 1, and a slider 17 slidably arranged in the sliding sleeve 16;

[0053] A rack 18 is provided on the side wall of the slider 17, and an avoidance groove for the rack 18 is opened on the side wall of the sliding sleeve 16. A support block 19 is provided at the bottom end of the slider 17, and a driving module for driving the slider 17 to slide in the vertical direction is also provided between the front and rear bottom ends of the support frame 1.

[0054] like Figure 1 and Figure 4 As shown, the driving module includes a driving shaft 20 whose axis is parallel to the front-to-back direction of the support frame 1, and both ends of the driving shaft 20 are rotatably mounted on the support frame 1;

[0055] Both ends of the driving shaft 20 are equipped with first gears 21, which are engaged with the rack 18 for transmission. A driving motor 22 is also installed on the support frame 1, and the power output shaft of the driving motor 22 and the driving shaft 20 are transmitted through a synchronous belt module 24.

[0056] In this embodiment, the drive motor 22 is a brake motor. When the digital starter moves to a predetermined position, the drive motor 22 rotates forward, causing the slider 17 and support block 19 to slide out, releasing the universal wheel 15 from the ground. The support block 19 supports the digital starter, effectively preventing any disruption to the athlete's race caused by displacement or offset of the starter. After the athlete starts, the drive motor 22 rotates backward, releasing the support block 19 from the ground, allowing the universal wheel to contact the ground, facilitating quick removal of the starter from the cycling race track.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit it. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the present invention can still be modified or replaced by equivalents. Any modification or equivalent replacement that does not depart from the spirit and scope of the present invention should be included in the scope of protection of the claims of the present invention.
