[0002] In the construction of a modern comprehensive training system, the deployment ability of a dynamic obstacle system directly affects the effect of scenario simulation training.

[0007] As a further improvement of the present invention, the axial adjustment mechanism includes a gravity member sleeved on the central rod and axially slidable along the central rod, a transmission member is hinged to the side wall of the gravity member, the other end of the transmission member is hinged to the middle of the support rod, and a drive control mechanism is arranged on the central rod, and the drive control mechanism acts on the gravity member to drive the gravity member to axially slide.

[0008] As a further improvement of the present invention, the axial adjustment mechanism further includes a mounting post provided at the lower end of the central rod. A separation groove for the mounting post to penetrate into is formed at the upper end of the ground pile. A preloading elastic member is arranged in the separation groove for providing a preloading separation force. In addition, a releasable locking device is arranged on the central rod for restricting the mounting post in the separation groove.

[0009] As a further improvement of the present invention, the locking device includes a locking member arranged in the mounting post and capable of radially penetrating out of the mounting post and the ground pile. A reset elastic member is arranged in the mounting post. A limiting member is sleeved on the central column. The inner wall of the limiting member abuts against the locking member for restricting the locking member from disengaging from the mounting post. The upper end of the limiting member is connected to the gravity member for axially sliding along with the gravity member.

[0010] As a further improvement of the present invention, the limiting member is provided with a penetrating hole.

[0016] Advantages of the present invention: 1. In this invention patent, by cooperating the support rods with the flexible skin assembly, a hollow triangular pyramid structure is formed, which can be deployed in scenarios such as beaches and woodlands. The structure is simple. Since the upper ends of the support rods are hinged to each other and the skin assembly is a flexible one, the triangular pyramid structure formed in this embodiment can be unfolded and folded, that is, it has an unfolded state and a folded state.

[0017] 2. When deploying the triangular pyramid structure, control the pointed spiked part at the lower end of the ground pile to anchor into the ground to form a stable mechanical fulcrum, effectively resisting the horizontal shear force and overturning moment caused by wind load, thereby preventing the triangular pyramid structure from being blown or overturned by the wind; in addition, the conical design of the spiked part can penetrate hard ground surfaces (such as frozen soil and gravel layers), and cooperate with the vertical pressure of the central rod to achieve rapid anchoring.

[0018] 3. During the training process, the triangular pyramid structure can be controlled to fold through the axial adjustment mechanism to meet the training requirements for simulating the dynamic changes of obstacles in the real scene.

[0019] 4. The gravity component has a certain weight, which can increase the total weight of the triangular pyramid structure, and the gravity component is located on the central axis of the triangular pyramid structure, reducing the center of gravity position of the triangular pyramid structure, and further reducing the risk of overturning caused by external forces (such as wind load and vibration).

[0020] 5. When it is necessary to control the triangular pyramid structure to fold, release the locking device so that the locking device no longer restricts the mounting column. Under the action of the preloaded elastic component, drive the central rod to move upward along the axis. At this time, the central rod is separated from the ground pile, that is, the support rods no longer need to overcome the anchoring force between the ground and the ground pile, and can be folded to improve the folding efficiency of the support rods, meet the training requirements, and ensure the training effect.

[0021] 6. The locking device can be indirectly controlled to unlock through the electromagnet, without the need to additionally set an unlocking mechanism, reducing the number of components, simplifying the structure, avoiding structural redundancy of this triangular pyramid structure, and improving the overall compactness.

Specific embodiments

[0024] The present invention will be further described in detail below with reference to the drawings and embodiments.

[0025] The orientation terms such as up, down, left, right, front, back, front side, back side, top, bottom, etc. mentioned or possibly mentioned in this specification are defined with respect to the structures shown in the respective drawings. The terms "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component. They are relative concepts and may accordingly change depending on their different positions and different usage states. Therefore, these or other orientation terms should not be construed as restrictive terms.

[0026] Refer to Figures 1 to 5 What is disclosed in the embodiment of the present invention is: A simulated triangular pyramid includes three support rods 1 distributed radially. The upper ends of the support rods 1 are hinged to each other through a vertex hinge assembly 5 to form a vertex. A flexible skin assembly 2 is wrapped between adjacent support rods 1. The skin assembly and the support rods 1 together enclose a hollow triangular pyramid structure A with a lower opening. In this embodiment, through the cooperation of the support rods 1 and the flexible skin assembly 2, a hollow triangular pyramid structure A is formed, which can be deployed in scenarios such as beaches and woodlands. The structure is simple. And because the upper ends of the support rods 1 are hinged to each other and the skin assembly is a flexible skin assembly, the triangular pyramid structure A formed in this embodiment can be unfolded and folded, that is, it has an unfolded state and a folded state. During transportation, the triangular pyramid structure A can be folded to facilitate storage and transportation. During training, the triangular pyramid structure A can be controlled to unfold for deployment. After the training is over, the triangular pyramid structure A is controlled to fold for withdrawal. That is, the triangular pyramid structure A in this embodiment can be quickly unfolded or folded to achieve rapid deployment, withdrawal and stacking. After withdrawal, it is also conducive to storage and can be reused, thereby reducing the training cost and labor cost, and having the effect of reducing costs and increasing efficiency.

[0027] However, since the triangular pyramid is only formed by the flexible skin assembly 2 and the support rods 1, its total weight is relatively low, and it is easily blown by the wind or overturned during deployment. Based on this, in this embodiment, a central rod 3 is vertically arranged on the central axis of the triangular pyramid structure A. The upper end of the central rod 3 is connected to the vertex hinge assembly 5. The lower end of the central rod 3 is provided with a ground pile 4. The ground pile 4 is detachably connected to the central rod 3 and penetrates downward through the lower opening. The lower end of the ground pile 4 is provided with a spike portion for penetrating into the ground. When deploying the triangular pyramid structure A, control the spike portion at the lower end of the ground pile 4 to be anchored into the ground to form a stable mechanical fulcrum, effectively resisting the horizontal shear force and overturning moment caused by the wind load, thereby preventing the triangular pyramid structure A from being blown or overturned by the wind. In addition, the conical design of the spike portion can penetrate hard ground surfaces (such as frozen soil and gravel layers), and cooperate with the vertical pressure of the central rod 3 to achieve rapid anchoring.

[0028] In addition, during the training process, it is also necessary to control the triangular pyramid structure A to automatically fold to simulate the dynamic changes of obstacles in the real scene, or to change the obstacle density in real time to achieve progressive difficulty training. Based on this, an axial adjustment mechanism is arranged between the central rod 3 and the ground pile 4. The axial adjustment mechanism is used to drive the central rod 3 to axially displace away from the ground pile 4 and control the triangular pyramid structure A to convert from the unfolded state to the folded state. During the training process, the triangular pyramid structure A can be controlled to fold through the axial adjustment mechanism to meet the training requirements of simulating the dynamic changes of obstacles in the real scene.

[0029] Specifically, the axial adjustment mechanism includes a gravity member 6 which is sleeved on the center rod 3 and can slide axially along the center rod 3. The side wall of the gravity member 6 is hinged with a transmission member 8. The other end of the transmission member 8 is hinged to the middle of the support rod 1. A drive control mechanism is provided on the center rod 3. The drive control mechanism acts on the gravity member 6 to drive the gravity member 6 to slide axially. In this embodiment, the gravity member 6 has a certain counterweight, which can increase the total weight of the triangular pyramid structure A, and the gravity member 6 is located on the structural central axis of the triangular pyramid structure A, thereby lowering the center of gravity position of the triangular pyramid structure A and further reducing the risk of overturning due to external forces (such as wind loads and vibrations).

[0030] In this embodiment, the driving control mechanism includes an electromagnet 7 arranged on the central rod 3, and the electromagnet 7 can attract or repel the gravity member 6 (in this embodiment, a magnetic member is arranged inside the gravity member 6, or the gravity member is a magnetic member) to drive the gravity member 6 to slide axially; when laying out, the electromagnet 7 is first started, and the electromagnet 7 absorbs the gravity member 6. Since the gravity member 6 is connected to the transmission member 8, the transmission member 8 drives the support rod 1 to expand outward. At this time, the triangular pyramid structure The structure A is unfolded and enters the unfolded state, and then the lower end of the ground pile 4 is controlled to penetrate into the ground, so that the triangular pyramid structure A is arranged. The structure is simple and the arrangement is convenient. At the same time, when it is necessary to control the triangular pyramid structure A to automatically collapse, the magnetic pole of the electromagnet 7 is controlled to change. At this time, the gravity member 6 repels the electromagnet 7, and at the same time, the gravity member 6 is acted on by gravity and slides axially downward along the center rod 3. At this time, the gravity member 6 is transmitted to the transmission member 8, thereby applying an inward contraction force to the support rod 1 of the triangular pyramid structure A. Figure 5 As shown, at this time, since the triangular pyramid structure A is arranged on the ground, the lower end of the support rod 1 is in contact with the ground, and the support rod 1, the center rod 3 and the ground form a triangular structure B. If the support rod 1 is retracted inward, the lower end of the support rod 1 and the lower end of the center rod 3 are close to each other, that is, in the triangular structure B, the length of the hypotenuse remains unchanged (corresponding to the support rod 1), and the length of the base becomes smaller (corresponding to the distance between the lower end of the support rod 1 and the central axis of the triangular pyramid structure A), then the height (corresponding to the center rod 3) needs to be increased accordingly. Based on this, in the process of the support rod 1 being retracted inward, the center rod 3 will be driven to move upward, and the ground pile 4 will be driven to leave the ground, so that the triangular pyramid structure A can be converted from the expanded state to the retracted state, and it will automatically tip over after being retracted, thereby meeting the training needs; in addition, when withdrawing, the triangular pyramid structure A can also be controlled to be retracted by controlling the electromagnet 7, which is convenient for withdrawal and improves withdrawal efficiency.

[0031] However, with the above settings, when controlling the automatic retraction of the triangular pyramid structure A, it is necessary to overcome the anchoring force (friction force) between the ground pile 4 anchored in the ground and the ground in order to control the upward movement of the central rod 3. However, when the ground pile 4 is excessively anchored in the ground, or in special terrains such as frozen soil, dense rock geology, and soft sandy land, the anchoring force between the ground and the ground pile 4 significantly increases, resulting in an increase in the resistance to the upward movement of the central rod 3, and further causing the support rod 1 not to be retracted, or reducing the retraction efficiency, and driving the central rod 3 to move upward during the retraction process for retraction. Based on this, in this embodiment, the ground pile 4 is detachably connected to the central rod 3. Specifically, the axial adjustment mechanism further includes a mounting post 9 provided at the lower end of the central rod 3. The upper end of the ground pile 4 is provided with a separation groove 10 for the mounting post 9 to penetrate into. A preloading elastic member 11 is provided in the separation groove 10, and the preloading elastic member 11 is used to provide a preloading separation force. In addition, a releasable locking device is provided on the central rod 3 to limit the mounting post 9 in the separation groove 10. That is, the lower end of the central rod 3 is connected to the ground pile 4 through the locking device. When it is necessary to control the retraction of the triangular pyramid structure A, the locking device is released so that the locking device no longer restricts the mounting post 9. Under the action of the preloading elastic member 11, the central rod 3 is driven to move upward along the axis. At this time, the central rod 3 is separated from the ground pile 4, that is, the support rod 1 no longer needs to overcome the anchoring force between the ground and the ground pile 4 directly, and can be retracted, and the retraction efficiency of the support rod 1 is improved to meet the training requirements and ensure the training effect.

[0032] In this embodiment, the locking device includes a locking member 12 disposed in the mounting post 9 and capable of radially extending out of the mounting post 9 and the ground pile 4. A reset elastic member 17 is disposed in the mounting post 9. A limiting member 13 is sleeved on the central rod 3. The inner wall of the limiting member 13 abuts against the locking member 12 to limit the locking member 12 from detaching from the mounting post 9. The upper end of the limiting member 13 is connected to the gravity member 6 to axially slide along with the gravity member 6. As shown in the figure, the limiting member 13 is provided with a through hole. When the gravity member 6 drives the limiting member 13 to move down to a predetermined position, the through hole is aligned with the locking member 12. At this time, the locking member 12 is pushed by the reset elastic member 17 to extend out of the ground pile 4 and no longer restricts the mounting post 9 from detaching from the separation groove 10, that is, the unlocking of the locking device is realized. The structure is simple, and the movement of the limiting member 13 is driven by the gravity member 6, and then the unlocking of the locking device is realized. The two are interconnected, so that during the process of the support rod 1 being retracted, the central rod 3 can rise synchronously, that is, immediately after the central rod 3 detaches from the ground pile 4, the triangular pyramid structure A can be retracted, and the triangular pyramid structure A can immediately fall after being retracted, thereby improving the response speed of the triangular pyramid structure A and ensuring the training effect. In addition, the locking device can be unlocked by the electromagnet 7, and there is no need to additionally set up an unlocking mechanism, reducing the number of components, simplifying the structure, avoiding structural redundancy of the triangular pyramid structure A, and improving the overall compactness.

[0033] The drive control mechanism further includes a signal receiver 14, a controller (not shown in the figure), and a signal transmitter (not shown in the figure) that are electrically connected to the electromagnet 7. Among them, the signal receiver can be installed inside the flexible skin assembly 2 to receive control signals and then transmit the control signals to the controller. The controller controls the start or pole conversion of the electromagnet 7 to perform real-time control, thereby meeting different training requirements.

[0034] The limiting member 13 is a ball. The side wall of the ground pile 4 is provided with a locking hole 15 for the ball to slide out. The diameter of the locking hole 15 is larger than the diameter of the ball, and the depth of the locking hole 15 is smaller than the diameter of the ball. Through the above settings, part of the ball is located in the locking hole 15 and part is located in the mounting post 9 to achieve the limiting function. At the same time, the ball structure slides out of the locking hole 15 more smoothly, that is, the locking device can be unlocked faster, further improving the retraction response speed of the triangular pyramid structure A.

[0035] The central rod 3 is hollow. The lower end of the central rod 3 is threadedly connected to the mounting post 9, so that the mounting post 9 and the lower end of the central rod 3 are detachably replaceable, improving the interchangeability of components.

[0036] The vertex hinge assembly 5 includes a connecting sleeve 501 provided on the central rod 3, and each of the support rods 1 is hinged to the connecting sleeve 501. The connection of multiple hinge points is achieved through the connecting sleeve 501, simplifying the assembly process.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
