[0023] The present invention is described in detail below in conjunction with the accompanying drawings and embodiments as a further preferred explanation:

[0024] Embodiment 1

[0025] Please refer to Figure 1-4 A projectile with a self-righting function comprises a projectile body 100 and a plurality of legs 200 for supporting the projectile body 100 to achieve the right position. The legs 200 are rotatably connected to the projectile body 100. Springs 300 are arranged between the legs 200 and the projectile body 100 to expand the legs 200 through elastic force. After the legs 200 are expanded by the springs 300, they are supported on the ground to right the projectile body 100. A limiting member 400 is arranged on the projectile body 100. The limiting member 400 limits the legs 200 to make the legs 200 retract to the outer periphery of the projectile body 100. The limiting member 400 is connected to a travel switch to make the limiting member 400 achieve reciprocating motion, thereby limiting or separating from the legs 200.

[0026] The basic principle of this scheme is that the thrown object body 100 is the hardware body for implementing subsequent work in the throwing action. The hardware body is equipped with different functional modules and accessories according to different usage backgrounds, such as a signal generator, a camera, and a recorder in a satellite beacon; a fluorescent plate or a reflective sheet in a material airdrop, and a temperature sensor in a fire scene. Not limited to the above specific examples, everything depends on the usage scenario and technical settings and conditions. Since it is difficult for the thrown object body 100 to achieve the target orientation by itself, the support leg 200 is set to help it to be positioned. Specifically, the support leg 200 is driven to unfold by a spring 300 to achieve the position. Based on this, before the position-correcting action occurs, the support leg 200 needs to be folded and stabilized, so the limiter 400 is set to stabilize the folded support leg 200. When the support leg 200 is folded to the outer periphery of the back-thrown object body 100, the limiter 400 acts on the support leg 200 to stabilize the folded state. The mechanical action of the limiter 400 is reciprocating motion, so it is connected to a travel switch to realize its reciprocating motion. In this way, the limiter 400 can be limited and opened relative to the support leg 200 by controlling the travel switch, so as to stably fix or release the support leg 200. The use of the travel switch can also help realize the electronic control of the action, and then can be connected to various signal systems and control systems that trigger the travel switch.

[0027] Furthermore, a plurality of legs 200 are arranged along the circumference of the object 100 , and the circumferential spacing between two adjacent legs 200 is the same or different, and the axial spacing between two adjacent legs 200 is the same or different.

[0028] In this preferred embodiment, the specific angular orientation of the body 100 of the thrown object after it is positioned is achieved by limiting the axial spacing and vertical spacing of each adjacent leg 200. The principle of this solution is to use the position and height difference of the legs 200 to achieve the orientation of the body 100 of the thrown object after it is positioned; for example, the lengths of several legs 200 are the same, and the circumferential spacing between two adjacent legs 200 is the same, and the axial spacing is 0. If the ground is a plane, the final orientation must be vertically upward. In other cases, if the body 100 of the thrown object is not required to be vertically upward, but tilted at a certain angle, it can be achieved by setting the spacing between two adjacent legs 200 as described above, and different spacings result in different angles, and a large operating range. Based on the same idea, in theory, this purpose can also be achieved by using springs with different actual strokes as springs 300.

[0029] Furthermore, the rotatable connection between the support leg 200 and the main body 100 of the thrown object is close to the bottom of the main body 100 of the thrown object, and the support leg 200 is deployed toward the bottom of the main body 100 of the thrown object by the elastic force of the spring 300.

[0030] In the preferred embodiment, the deployment direction of the legs 200 is limited, that is, it is limited that after being positioned upright, the bottom of the body 100 of the thrown object faces the ground.

[0031] Furthermore, a counterweight is disposed inside the body 100 of the thrown object, and the counterweight is close to the bottom of the body 100 of the thrown object.

[0032] In this preferred embodiment, the setting of the counterweight ensures that the end that touches the ground is the bottom, which facilitates the activation of the support leg 200.

[0033] In the specific implementation, in order to prevent accidental opening, a protective ring can be provided outside the supporting legs 200 to bind all the supporting legs 200. The protective ring is removed before use.

Further, along the bottom to top direction of the projectile body 100, the shell 110 includes a bottom shell plate 111, a middle shell seat 112, a middle cylinder shell 113 and a top shell cap 114. The middle shell seat 112 is connected to the bottom of the middle cylinder shell 113 and closes the bottom end of the middle cylinder shell 113. The bottom end surface of the middle shell seat 112 is provided with an ear plate so as to be rotatably connected to the support leg 200. The bottom shell plate 111 is located below the middle shell seat 112, and the connection where the support leg 200 is rotatably connected to the middle shell seat 112 is located between the middle shell seat 112 and the bottom shell plate 111, and the top shell cap 114 is connected to the top of the middle cylinder shell 113. Furthermore, the thrown object body 100 also includes an inner support member 120, and one end of the inner support member 120 extends into the interior of the middle cylinder shell 113 from the upper end thereof, and the top shell cap 114 covers the other end of the inner support member 120; the inner support member 120 is hollow, and a fixed shaft 121 is fixed and vertically arranged inside the inner support member 120, and a sliding sleeve 122 is slidably arranged on the fixed shaft 121; the limit member 400 passes through the top shell cap 114 and the inner support member 120 in sequence, and extends into the interior of the inner support member 120, and the inner end of the limit member 400 is connected to the sliding sleeve 122; the travel switch 160 is arranged in the middle cylinder shell 113, and the push rod that realizes reciprocating motion on the travel switch 160 is connected to the sliding sleeve 122 through a connecting member to drive the sliding sleeve 122 to slide along the fixed shaft 121, and the push rod is connected to a return spring 180 for resetting the push rod movement. Furthermore, the projectile body 100 further includes a battery pack 130, and the battery pack 130 is located in the middle cylinder shell 113, and the battery pack 130 is close to the bottom end of the middle cylinder shell 113 to play a counterweight effect. Further, the projectile body 100 further includes a bottom pad 140 and a circuit board 150, the bottom pad 140 is located in the middle cylinder shell 113 and below the battery pack 130, and the circuit board 150 is located above the battery pack 130 and adhered to the bottom end surface of the inner support 120.

[0038] like Figure 1-4 As shown, this embodiment provides a specific structure and setting form of a tilt sensor. As a geographical monitoring means, the field deployment of the tilt sensor can play a role in monitoring situations such as landslides. The same geographical monitoring sensors include rainfall sensors.

[0039] The principle and use process of the solution in this embodiment during specific implementation are as follows:

[0040] The support leg 200 has a strip-shaped structure and can be made of a metal material with high rigidity. Figure 2 As shown, in this embodiment, the number of the legs 200 is eight, but the actual design and manufacture of the product is not limited to eight legs 200, and can be twelve or sixteen, etc. The spring 300 adopts a torsion spring, and can also adopt a tension spring or a compression spring. Since the working principles of tension springs and compression springs are different from those of torsion springs, and the directions of elastic force are different, if tension springs or compression springs are adopted, it is necessary to set a specific and appropriate setting structure. Based on the torsion spring adopted in this embodiment, an ear plate and a baffle are provided on the middle shell seat 112 to form a groove-like structure to accommodate the torsion spring. The number of legs 200 and the limiting member 400 are the same, and the positions correspond one to one. When the legs 200 are folded, the legs 200 press the torsion spring, and the suspension end is clamped by the limiting member 400 to achieve limiting. The limiting member 400 is a rigid metal component, such as Figure 3 As shown, in the present embodiment, it is configured as a thin strip. One end for clamping the limiting member 400 is hook-shaped, and the upper end of the support leg 200 is hooked to achieve folding and fixing. The force of the limiting member 400 to clamp the support leg 200 comes from the travel switch 160. The travel switch 160 is triggered according to a triggering method set in advance, and the sliding sleeve 122 is pulled by the driving connecting member 170 of the push rod 161, thereby driving the limiting member 400 connected to the sliding sleeve 122 to achieve the separation of the support leg 200. Based on the need for repeated actions, a return spring 180 is provided at the travel switch 160 to help the push rod 161 to return to its original position. As shown in FIG. Figure 3 and 4 As shown, in this embodiment, the connecting member 170 is a rigid wire drawing (the force is axial, and based on the complexity of the actual material, the rigidity is understood as the effect of axial rigidity), and is rotatably connected to the push rod 161 to facilitate the expansion of its range of motion. Similarly, the limiter 400 and the sleeve 122 are also rotatably connected to facilitate the expansion of its range of motion. In the case of the above-mentioned expanded range of motion, the corresponding components and structures can ensure that the overall structure is more resilient when they are impacted, rather than being brittle and being destroyed by the impact. The connection between the connecting member 170 and the sleeve 122 is also an axially movable connection, which can also play the role of dissolving the impact force.

[0041] The housing 110 is composed of a bottom housing 111, a middle housing seat 112, a middle cylinder housing 113 and a top housing cap 114. Figure 2 and 3As shown, the rotatable end of the support leg 200 is arranged between the bottom shell 111 and the middle shell seat 112. The counterweight is achieved by the battery pack 130, and the counterweight is at the bottom position of the whole. When the whole falls, the bottom shell 111 touches the ground under the influence of the counterweight, and then bounces again, which is easy to fall sideways. In this way, it is in a non-correct position. The travel switch 160 is triggered, and the limit member 400 is disengaged from the support leg 200. Under the strong elastic force of the torsion spring itself, the support leg 200 unfolds each support leg 200. Based on the spatial range generated by the torsion spring setting, the support leg 200 is unfolded and flattened to achieve the correct position. In order to improve the gripping ability of the support leg 200 when it is unfolded and in the correct position, a positioning cone 210 is provided on each support leg 200.

[0042] In this embodiment, the travel switch 160 is a linear travel switch, having a push rod 161 that realizes linear reciprocating motion. The push rod 161 realizes a unidirectional motion to trigger the limiter 400. Regardless of whether the push rod 161 is pushed or pulled when the travel switch 160 is triggered, a return spring 180 is provided to help the push rod 161 reset. Figure 3 As shown, the return spring 180 is a cone spring, and generally, a travel switch based on the principle of an electromagnet is provided with a spring to help the push rod return. Figure 3The specific structural setting provided is taken as an example. The push rod 161 of the travel switch 160 moves toward the bottom of the entire device as a triggering action. When the push rod moves toward the bottom of the device, it pulls the connecting member 170, and then drags the sleeve 122 to move toward the bottom of the device. Based on the setting structure of the sleeve 122 and the limit member 400 (the limit member 400 forms a lever, and the fulcrum is at the position of the hole on the inner support member 120 for the limit member 400 to pass through), the outer end of the limit member 400 (the hook-shaped setting toward the bottom of the device) is separated from the support leg 200. In this way, in order to ensure that the limiter 400 can stably limit the support leg 200 in a non-touch-triggered state, a limiter spring (not shown in the figure) is provided to provide a force for the limiter 400 to limit the state. Specifically, the limiter spring is a tension spring, and one end is connected to the sliding sleeve 122, and the other end is connected to the top of the inner support member 120. The tension of the limiter spring acts on the limiter 400 formed as a lever, and then the outer end of the limiter 400 hooks the support leg 200 toward the bottom of the device, forming a strong limit. From the perspective of the direction of action on the sliding sleeve 122, the travel switch 160 and the limiter spring are opponents, and the actual force of the travel switch 160 is much greater than the force of the limiter spring, so that the travel switch 160 can be effectively used as the force generating party of the triggering action. The setting of the limiter spring can play an effective role under relatively small force, and it is also necessary to cooperate with the hook-shaped limiter structure and set the limiter as a lever. The above is explained using a specific structural form as an example. In the specific implementation, based on the same principle, there may be other forms. For example, the hook-shaped limiting structure at the outer end of the limiting member 400 faces upward, so the functional device and its force acting on the sliding sleeve 122 inside only need to be set in the opposite direction. In the above specific structural form, the limiting spring is a tension spring. Since the sliding sleeve 122 needs to move toward the top to achieve its effect, based on the elastic force characteristics, a compression spring may be set in the opposite direction. This is the application technology of the spring and a conventional technical means, which will not be elaborated here. It should be noted that the use of various springs and the settings based on the characteristics of the adopted springs are all considered to be the same in this solution.

[0043] In specific implementation, Figure 3 and 4 As shown, in order to power the circuit inside the device, a solar panel 190 is provided on the top shell cap 114, and in order to ensure wind resistance, the solar panel is non-expandable.

[0044] The preferred specific embodiments of the present invention are described in detail above. It should be understood that a person skilled in the art can make many modifications and changes based on the concept of the present invention without creative work. Therefore, any technical solution that can be obtained by a person skilled in the art through logical analysis, reasoning or limited experiments based on the concept of the present invention on the basis of the prior art should be within the scope of protection determined by the claims.
