Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

Fig. 1 to 5 show a can-type drone. The tank type drone includes at least a tank body 1, a sensor 2, and a control unit 3. The tank 1 is used as a shooting target for shooting. The sensor 2 is disposed inside the tank 1. The control unit 3 is electrically connected to the sensor 2. Under the condition that the tank body 1 is hit and vibration data can be generated, the sensor 2 can acquire the vibration data generated by the tank body 1 through the tank body 1 and send the vibration data to the control part 3.

Preferably, the sensor 2 is disposed inside the tank body 1 to detect whether the tank body 1 vibrates/shakes.

Preferably, the control unit 3 is electrically connected to the sensor 2.

Preferably, the indicator light unit 6 comprises at least one first indicator light 601. Under the condition that the tank body is hit by a foreign object and can generate vibration/shake, the indicator lamp 601 can be electrically connected with the control part 3 to mark whether the tank body is hit by the foreign object and generates vibration/shake.

Preferably, the sensor can be used to detect vibration of the tank caused by impact of foreign objects.

Preferably, the indicator light is illuminated to indicate that the tank is hit by the foreign object to generate vibration/sloshing.

Preferably, the can body 1 has a cylindrical shape. Preferably, the can body 1 may also take other shapes.

Preferably, the shock data may include, but is not limited to: acceleration/velocity data along the x-axis, y-axis, z-axis of the can body 1, amplitude and/or frequency of vibration along the x-axis, y-axis, z-axis of the can body 1, and the like. Preferably, the vibration data may further include: the number of the can body 1 corresponding to the vibration data, the time stamp of the vibration data, and the like. Preferably, the vibration data can be represented by two numerical values, namely zero and one, for example, zero indicates that the tank 1 has not been vibrated, that is, the tank 1 has not been hit; one means that the tank 1 is shaken and the tank 1 is hit by water bullet or the like.

Preferably, the can body 1 is internally provided as a cavity. Through the arrangement mode, the tank body 1 can generate crisp sound after being hit by water bullets and the like, so that the shooting experience of shooting personnel is improved; on the other hand, the mass of the tank 1 is not so large that the tank 1 cannot generate vibration after being hit by water bullet or the like or the vibration is too weak to be detected by the sensor 2.

Preferably, the cavity inside the can 1 can be used for mounting other components such as the sensor 2 and the control section 3. Preferably, the can body 1 is made of a metal material, for example, the can body 1 may be a hollow iron can. Through the configuration mode, when a user shoots and hits the tank body 1, the tank body 1 can generate crisp shooting sound, so that the shooting experience of the user can be enhanced.

Preferably, the sensor 2 may be an acceleration sensor 2. The sensor 2 can adopt the prior art, for example, an acceleration sensor with the model number of CA-YD-1182 can be adopted, and an acceleration sensor with the model number of LIS2DW12TR can also be adopted. For example, when the acceleration sensor 2 of the sensor 2 detects that the acceleration or the vibration value in one of the x-axis, the y-axis, and the z-axis of the can body 1 in a certain direction exceeds a preset threshold value, the control section 3 determines that the can body 1 is hit by a foreign object such as a water bullet. Preferably, the preset threshold value can be flexibly set according to the requirements of the actual scene. For example, the preset threshold may be zero.

Preferably, the tank 1 can be used as a fixed target drone. For example, a user may place a canned drone at a particular location, either indoors or outdoors, to act as a fixed target for a shooter.

Preferably, the control part can adopt the prior art, for example, a single chip microcomputer of MCS-51 series model is adopted. It should be noted that, this technical solution does not relate to the improvement of the software/method used by the control unit, and only uses the existing technology (for example, a single chip microcomputer, an acceleration sensor, etc.) to integrate in terms of assembly/hardware, and does not require the protection of the software/method used by the control unit. In short, after the sensor detects the vibration/shaking of the tank, the first indicator light is turned on immediately to indicate that the tank is hit by a foreign object to generate vibration or shaking.

Preferably, the sensor 2 inside the canned drone is used to detect if a water bullet gun or the like hits the can body 1 when shooting the drone, i.e. the can body 1. With this arrangement, the sensor transmits the acquired vibration data of the tank body to the control unit, so that the control unit can quickly determine that the tank body is hit by a foreign object (e.g., a water bullet), and if the control unit does not receive the data transmitted by the sensor, it indicates that the foreign object has not hit the tank body.

According to a preferred embodiment, the tank comprises a first tank 102 and a second tank 103, wherein the end of the second tank far away from the ground gradually bends and extends towards the axial center line of the second tank and is integrally and smoothly connected to the first tank.

Therefore, through the configuration mode, the sensor 2 is arranged on the inner wall of one end far away from the ground along the axial direction of the tank body 1 in a magnetic attraction mode, so that when the force of the sensor 2 for shooting at a long distance or hitting the tank body 1 by a foreign object is very weak, vibration data can be acquired from the weak vibration amplitude/frequency and the like of the tank body 1 along the horizontal direction, and the vibration data is sent to the control part 3 to indicate that the tank body 1 is hit by the foreign object such as a water bomb.

Preferably, the sensor 2 is detachably connected to the side of the control part remote from the inner wall of the cavity. By the arrangement mode, on one hand, the components of the canning target machine can be conveniently detached; on the other hand, because the control part 3 is in direct contact with the tank body 1 in a magnet adsorption manner, the vibration (for example, the vibration generated by the tank body 1 after the water bomb hits the outer surface of the tank body 1) suffered by the tank body 1 can strictly follow the transmission theorem, namely, the vibration data transmission function, and the vibration information after the water bomb hits is transmitted to the control part 3 and the sensor 2 arranged on the control part 3 through the mode, so that the loss of the vibration wave in the transmission process is reduced as much as possible, and the vibration data of the tank body 1 can be directly and effectively collected by the sensor 2 arranged on the control part 3.

According to a preferred embodiment, the axial centre line of the cavity 101 coincides or substantially coincides with the axial centre line of the second can, wherein the distance between the side wall of the cavity and the outer wall of the second can in the radial direction of the cavity is the same.
