[0035] Example

[0036] like Figure 1 - Figure 4 As shown, the multimodal interactive timing device based on object collision sensing includes an upper cover assembly, a core assembly, and a base assembly. The upper cover assembly includes an upper cover 2 and a semi-transparent upper cover plate 1 adhered to the top surface of the upper cover 2.

[0037] The core assembly is located at the bottom of the upper cover assembly, including a core shell 3 connected to the upper cover 2. The core shell 3 contains a switch positioning post 31, a micro switch 36 fixed to the switch positioning post 31, an elastic reset mechanism, an energy module, and a circuit module. A button post 12 fixed to the upper cover 1 is located directly above the micro switch 36.

[0038] The top cover 2 is elastically connected to the core shell 3 via an elastic reset mechanism. The elastic reset mechanism consists of multiple symmetrically distributed sets. Each set of elastic reset mechanisms includes a spring baffle post 32 fixedly installed on the core shell 3, a spring baffle 38 detachably connected to the top of the spring baffle post 32 by screws, a spring 37 fixed to the top of the spring baffle 38, and a positioning shaft 11 fixed to the top cover 2. The positioning shaft 11 has holes for installing the spring 37.

[0044] A method for operating a multimodal interactive timing device based on object collision sensing, characterized by comprising the following steps:

[0045] S1: Collision Event Detection and Verification

[0046] When the object collides with the top cover plate 1:

[0047] The micro switch 36 generates a first pressure signal, and the weighing sensor 5 generates a second pressure signal. When the first pressure signal is in a closed state and the value of the second pressure signal is greater than a preset threshold, it is determined to be a valid collision event. The preset threshold is set to satisfy the following condition: preset threshold > maximum peak value of environmental vibration noise + safety margin.

[0048] S2: Working Mode Judgment

[0049] If four valid collisions are triggered consecutively, the device can switch between normal timing mode and query mode.

[0050] If the current timing mode is normal, proceed with steps S3-S7;

[0051] If the current mode is historical record query, proceed to step S8.

[0052] S3: Timing preparation response

[0053] In response to valid collision events:

[0054] Initialize and display the timer interface on screen 16;

[0055] The light source 52 is controlled to enter the dynamic light effect of the flowing light, that is, the flowing light effect. Multiple LED units in the light source 52 are lit up in sequence to form a unidirectional light wave sequence.

[0056] S4: Timed Start

[0057] When the microswitch 36 is detected to have returned to the open state, a 0.1ms precision timer is started.

[0058] S5: Real-time timing feedback

[0059] During the timing process:

[0060] The screen dynamically refreshes to display 16 timer values;

[0061] The hue parameter of light source 52 is adjusted in segments according to the timing duration. The adjustment rules for the hue parameter are as follows:

[0062] When the time length t∈[0,T1), output the first hue value H1;

[0063] When the time length t∈[T1,T2), output the second hue value H2;

[0064] When the time length t≥T2, output the third hue value H3;

[0065] T1 and T2 are preset time segmentation thresholds.

[0066] S6: End timing

[0067] When a valid collision event is detected again:

[0068] Stop the timer;

[0069] Store the current time value to the history queue;

[0070] Freeze the timing value on the display screen 16 and the current hue of the light source 52.

[0071] S7: Loop Triggering

[0072] Maintain the frozen state of S6 until the next valid collision event occurs, then return to S3;

[0073] During the freeze period:

[0074] The display screen refresh rate will be reduced to below 1Hz.

[0075] Turn off the hue adjustment function of light source 52 and maintain only the basic brightness.

[0076] S8: Record query operations

[0077] In historical record query mode:

[0078] Each time a valid collision event is detected, the display screen 16 switches to show the previous timing data in the history queue;

[0079] When more than four valid collision events are detected or there is no operation for 30 seconds, switch back to normal timing mode.

[0080] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
