[0060] The above drawings illustrate specific embodiments of the present application, which will be described in more detail below. These drawings and the textual description are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0061] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0062] Due to factors such as the flatness of the track, the dynamic balance of the ejection element itself, and external interference with the ejection element, the ejection element can vibrate while sliding on the track, making it easy for the ejection element to separate from the ejection mechanism, resulting in ejection failure. Simply increasing the connection strength between the ejection mechanism and the ejection element can make it difficult to separate from the ejection mechanism during takeoff, also leading to ejection failure and significantly compromising the reliability of the ejection element's launch.

[0063] To address the aforementioned problems with existing ejection elements during catapult launch, the present application provides an inertial release device comprising a support body, a flip frame, and an elastic support mechanism. The support body is slidably mounted on a track to provide the ejection element with an initial takeoff velocity. The support body has an acceleration mode and a deceleration mode. One side of the flip frame is connected to the support body, and the other side of the flip frame is provided with a connecting portion that can be connected to or disconnected from the ejection element. The flip frame deflects forward or backward relative to the support body to switch the connecting portion between a forward position and an upward position relative to the support body. The elastic support mechanism is disposed on the support body. In the acceleration mode, the flip frame deflects backward toward the support body, positioning the connecting portion in an upward position relative to the support body and connecting to the ejection element. The flip frame is connected to the elastic support mechanism to drive the ejection element to slide forward via the connecting portion. The elastic support mechanism causes the connecting portion to elastically abut against the ejection element, preventing it from disengaging. In deceleration mode, the connection portion disengages from the ejection element, and the flip frame deflects forward of the support body, positioning the connection portion in front of the support body. The flip frame then connects or disconnects from the elastic support mechanism, facilitating takeoff of the ejection element. This ensures that the ejection device remains essentially connected to the ejection element during acceleration, providing stable propulsion and less likely to disengage, thereby improving the reliability of catapult takeoff.

[0064] The technical solution of the present application will be described in detail below with reference to the accompanying drawings and several specific embodiments. It will be understood that the following embodiments can be combined or used individually.

[0065] like Figure 1-Figure 7 As shown, this embodiment provides an inertial release device that can be used for catapult takeoff of drones and aircraft. The inertial release device includes a track 100 and a sliding unit 200. The sliding unit 200 includes a supporting body 210, a flip frame 220 and an elastic support mechanism 230.

[0066] The support body 210 is slidably disposed on the rail 100 , and the support body 210 has an acceleration mode and a deceleration mode.

[0067] One side of the flip frame 220 is connected to the supporting body 210 , and the other side of the flip frame 220 is provided with a connecting portion 221 for connecting to the ejection member. The flip frame 220 rotates relative to the supporting body 210 .

[0068] The elastic support mechanism 230 is set on the support body 210. In the acceleration mode, the flip frame 220 deflects toward the rear of the support body 210, so that the connecting part 221 is located above the support body 210 and connected to the ejection member. The flip frame 220 is connected to the elastic support mechanism 230 to drive the ejection member to slide forward through the connecting part 221.

[0069] In the deceleration mode, the connection portion 221 is separated from the ejection member, and the flip frame 220 deflects toward the front of the support body 210 so that the connection portion 221 is located in front of the support body 210 , and the flip frame 220 is connected to or disconnected from the elastic support mechanism 230 .

[0070] In this embodiment, the track 100 is used to provide a sliding runway for the sliding unit 200 and the ejection element. That is, the sliding unit 200 and the ejection element can slide together on the track 100. The track 100 can have a linear sliding groove or a flat surface. Here, the ejection element can be a fixed-wing drone, an aircraft, or other objects that require catapult launch.

[0071] The support body 210 is used to provide a mounting base for at least the flip frame 220 and the elastic support mechanism 230. The support body 210 can be a frame structure and can be slidably mounted on the track 100 via guide wheels, rollers, guide mechanisms, etc. The power components required for the ejection can be mounted on the support body 210 or on the side of the track 100 and then connected to the support body 210.

[0072] The support body 210 has an acceleration mode and a deceleration mode, wherein the acceleration mode is used to provide the ejection member with an initial takeoff speed for takeoff, and the deceleration mode is used to separate from the ejection member and retract some mechanisms on the ejection device to avoid interfering with the takeoff of the ejection member.

[0073] The flip frame 220 is used to connect or disconnect with the ejection member. One end of the flip frame 220 can be connected to the support body 210 through a rotating shaft, a rotating seat, a bearing and other components. The deflection axis of the flip frame 220 is arranged horizontally and is perpendicular to the extension direction of the track 100. The flip frame 220 can be deflected to a horizontal position toward the front of the support body 210, or it can be deflected to a vertical position toward the rear of the support body 210.

[0074] A connecting portion 221 is provided on the side of the flip frame 220 away from the rotation center. The connecting portion 221 is used to connect to or disconnect from the ejection member. Therefore, the connecting portion 221 can be a structure such as a bayonet, which can be engaged with the wings, belly and other parts of the ejection member. The connecting portion 221 can be one or more and is only used to provide a unidirectional thrust to the ejection member.

[0075] The elastic support mechanism 230 is used to provide an elastic support force to the tilt frame 220 toward the front of the support body 210. The elastic support mechanism 230 can be an elastic component such as a spring or an accumulator. This prevents the tilt frame 220 from further deflecting toward the rear of the support body 210. Furthermore, in the acceleration mode, the elastic support provided by the elastic support mechanism 230 maintains the connection between the connecting portion 221 and the ejection member, preventing them from becoming disengaged.

[0076] Specifically, the ejection member is placed on the track 100. In the acceleration mode, the flip frame 220 deflects toward the rear of the support body 210, so that the connecting portion 221 is located above the support body 210 and connected to the ejection member. The flip frame 220 is connected to the elastic support mechanism 230, so that the ejection member slides forward through the connecting portion 221. Under the action of the elastic support mechanism 230, the connecting portion 221 elastically abuts against the ejection member, preventing separation. In the deceleration mode, the connecting portion 221 separates from the ejection member, and the flip frame 220 deflects toward the front of the support body 210, so that the connecting portion 221 is located in front of the support body 210 to avoid interference with the takeoff of the ejection member. The flip frame 220 is connected to or disconnected from the elastic support mechanism 230.

[0077] It can be understood that, compared with the structure in the prior art in which a rigid connection is used between the ejection device and the ejection member to provide a thrust, the inertia release device provided in this embodiment uses an elastic support mechanism 230 between the elastic device and the ejection member. While supporting and propelling the ejection member, the connection portion 221 on the flip frame 220 can move forward and backward with the ejection member to prevent separation from the ejection member, thereby improving the reliability of the ejection takeoff and being more adaptable to interference from the surrounding environment of the ejection device.

[0078] Thus, the inertia release device provided in this embodiment includes a track 100 and a sliding unit 200. The sliding unit 200 includes a support body 210, a flip frame 220, and an elastic support mechanism 230. The support body 210 is slidably set on the track 100 to provide an initial takeoff speed for the ejection member. The support body 210 has an acceleration mode and a deceleration mode. One side of the flip frame 220 is connected to the support body 210, and the other side of the flip frame 220 is provided with a connecting portion 221. The connecting portion 221 can be connected to or disconnected from the ejection member, and the flip frame 220 deflects forward or backward relative to the support body 210 to switch the connecting portion 221 between the front position and the upper position of the support body 210. The elastic support mechanism 230 is disposed on the support body 210. In acceleration mode, the flip frame 220 deflects toward the rear of the support body 210, positioning the connecting portion 221 above the support body 210 and connected to the ejection element. The flip frame 220 is connected to the elastic support mechanism 230, driving the ejection element to slide forward via the connecting portion 221. Under the action of the elastic support mechanism 230, the connecting portion 221 elastically abuts against the ejection element, preventing it from disengaging. In deceleration mode, the connecting portion 221 disengages from the ejection element, and the flip frame deflects toward the front of the support body 210, positioning the connecting portion 221 in front of the support body 210. The flip frame 220 connects and disconnects from the elastic support mechanism 230, facilitating the ejection element's launch. This ensures that the ejection device remains substantially connected to the ejection element during acceleration, providing stable propulsion and preventing disengagement, thereby improving the reliability of the ejection launch.

[0079] In one possible design, in the inertia release device provided in this embodiment, the elastic support mechanism 230 includes a support assembly 231 and a first elastic member 232. The support assembly 231 is connected to the support body 210 and slides toward the front or rear of the support body 210. The first elastic member 232 is connected to the support body 210. In acceleration mode, the flip frame 220 is connected to the support assembly 231, and the support assembly 231 abuts the first elastic member 232 to support the flip frame 220. In deceleration mode, the flip frame 220 is connected to or disconnected from the support assembly 231.

[0080] Specifically, refer to Figure 2-Figure 3As shown, the support assembly 231 may be a support rod assembly, etc. One end of the support assembly 231 may be connected to the rear of the support body 210 via a sliding member, a sliding structure, etc., and the support assembly 231 may slide toward the front or rear of the support body 210. The other end of the support assembly 231 is used to support the flip frame 220 and is connected to the flip frame 220. The first elastic member 232 may be a spring, etc., and a plurality of first elastic members 232 may be arranged side by side at the rear of the support body 210 to form an elastic resistance to the support assembly 231 in the forward direction.

[0081] In acceleration mode, the position between the connection portion 221 and the rotation center of the flip frame 220 is connected to the support assembly 231, driving the support assembly 231 backward and abutting against the first elastic member 232. When the ejection member and the connection portion 221 become loose, the first elastic member 232 drives the support assembly 231 forward, thereby quickly reconnecting the connection portion 221 to the ejection member and ensuring that it does not disengage. The elastic force of the first elastic member 232 can be determined based on the mass of the ejection member and the required initial ejection velocity, and is not specifically limited in this embodiment.

[0082] In the deceleration mode, the turning frame 220 is connected to or disconnected from the support assembly 231. That is, the turning frame 220 can always remain connected to the support assembly 231, or the turning frame 220 can also be disconnected from the support assembly 231 midway to avoid interference and quickly fall forward.

[0083] Furthermore, in this embodiment, the support assembly 231 includes a support member 2311 and a sliding member 2312 connected to the support member 2311. The sliding member 2312 is connected to the support body 210 and slides forward or backward relative to the support body 210 to provide an inertial force. The support member 2311 has a first support portion 2301 on the side facing away from the sliding member 2312. The flip frame 220 has a second support portion 222 that matches the first support portion 2301. In the acceleration mode, the first support portion 2301 is connected to the second support portion 222; in the deceleration mode, the first support portion 2301 and the second support portion 222 are connected or disconnected.

[0084] Specifically, continue as Figure 2 、 Figure 3 As shown, the support member 2311 can be a support plate, a support rod, a support frame, etc., and the sliding member 2312 can be a slider with a certain mass, etc. The sliding member 2312 can be slidably installed at the rear of the support body 210 through a sliding component, a sliding structure, etc. In the deceleration mode, the inertia force of the sliding member 2312 drives the flip frame 220 to deflect quickly toward the front and fall down through the support member 2311, avoiding interference with the tail part of the ejection member.

[0085] The first support portion 2301 and the second support portion 222 may be connected by a mutually abutting connection structure, such as a magnetic structure, or may be a mutually cooperating snap-fit ​​structure, so that the first support portion 2301 can support the second support portion 222 forward.

[0086] In order to make the supporting force of the support member 2311 on the flip frame 220 more balanced, the second support parts 222 are set on both sides of the flip frame 220 in a direction parallel to the rotation axis. Correspondingly, two corresponding first support parts 2301 are set on the side of the support member 2311 away from the sliding member 2312. The two support parts provide one-to-one support, which is more stable.

[0087] For example, in this embodiment, the support member 2311 rotates relative to the sliding member 2312. One of the first support portion 2301 and the second support portion 222 is a slot, and the other is a protrusion that matches the slot. In the acceleration mode, the slot and the protrusion are connected. In the deceleration mode, the slot and the protrusion are connected or disconnected.

[0088] In one example, Figure 3 As shown, the first supporting portion 2301 is a card slot, and the second supporting portion 222 is a card protrusion that matches the card slot. The card slot and the card protrusion are connected and rotate relatively. Figure 4 As shown, when the sliding member 2312 slides forward due to inertia, as shown in FIG. Figure 4 In the positive direction of the middle X, the flip frame 220 is pushed down quickly by the support member 2311.

[0089] In another example, not shown, the first support portion 2301 may be a latching protrusion, and the second support portion 222 may be a latching slot that matches the latching protrusion, the latching slot and the latching protrusion being connected and rotating relative to each other. When the sliding member 2312 slides forward due to inertia, the flip frame 220 can also be pushed down by the support member 2311 to quickly fall down.

[0090] In order to prevent the support member 2311 from rotating at a speed that cannot keep up with the speed at which the flip frame 220 falls and thus causing drag, an opening can also be left in the slot. If the first support portion 2301 is a slot, the opening on the slot faces the front of the support body 210, such as Figure 3 As shown, if the second support portion 222 is a card slot, the opening of the card slot faces the rear of the support body 210 so that the card slot and the card protrusion can be disengaged when the flip frame 220 falls down quickly.

[0091] In order to ensure that the flip frame 220 always has a tendency to fall toward the rear of the support body 210 when the connecting portion 221 on the flip frame 220 is in the upper position, thereby preventing it from naturally falling forward, in this embodiment, a counterweight portion 223 is provided on the flip frame 220 toward the rear of the support body 210, so that when the connecting portion 221 is in the upper position, the center of gravity of the flip frame 220 is biased toward the rear of the support body 210.

[0092] Specifically, if Figure 5 As shown, the counterweight portion 223 on the flip frame 220 has a certain mass and is located on the side close to the rear of the support body 210 and as close to the rotation axis as possible. In this way, the center of gravity G is biased toward the rear of the support body 210, so that when the flip frame 220 is basically in a vertical state, it naturally tilts backward and counteracts the support assembly 231.

[0093] It is worth noting that when the turning frame 220 falls toward the front of the supporting body 210, after the center of gravity G passes directly above the rotation center, the counterweight 223 can also assist the turning frame 220 and accelerate its falling.

[0094] The specific size and position of the counterweight portion 223 can be determined according to actual needs and are not specifically limited in this embodiment.

[0095] In order to prevent the flip frame 220 from rebounding after falling, in this embodiment, the sliding unit 200 further includes a locking assembly 240. When the flip frame 220 deflects toward the front of the supporting body 210 so that the connecting portion 221 is in the front position, the locking assembly 240 locks the flip frame 220.

[0096] In this way, by locking the flip frame 220 with the locking assembly 240, the flip frame 220 can be effectively prevented from falling forward and then rebounding, thereby affecting the tail of the ejection member. The locking assembly 240 is disposed at the front end of the support body 210 and can be a mechanical one-way locking mechanism, a magnetic locking mechanism, or the like.

[0097] For example, in this embodiment, the locking assembly 240 includes a locking member 241 and a second elastic member 242 connected to the locking member 241. The locking member 241 is provided on the support body 210. When the flip frame 220 is deflected toward the front of the support body 210 so that the connecting portion 221 is in the forward position, the flip frame 220 abuts against the locking member 241 and is locked.

[0098] Specifically, combined Figure 3 、 Figure 6 As shown, the locking member 241 can be a latch, a lock tongue or other components, and the locking member 241 can be installed at the front end of the support body 210 through a housing, a slide groove or the like, and the locking member 241 can move in a direction parallel to the rotation axis of the flip frame 220, such as along Figure 3 When the middle Z axis moves in the forward or reverse direction, one end of the locking member 241 is connected to the second elastic member 242 , which can be an elastic component such as a spring.

[0099] In this way, when the flip frame 220 deflects and falls toward the front of the supporting body 210, the side or end of the flip frame 220 can abut against the locking member 241. Under the elastic force of the second elastic member 242, the locking member 241 can lock the flip frame 220 to prevent rebound.

[0100] Furthermore, in this embodiment, one of the locking member 241 and the flip frame 220 has a locking protrusion 2411, and the other has a locking groove 224 that matches the locking protrusion 2411. When the flip frame 220 is deflected toward the front of the support body 210, so that the connecting portion 221 is in the forward position, the locking protrusion 2411 is connected to the locking groove 224.

[0101] Specifically, if Figure 6 As shown, when the flip frame 220 deflects toward the front of the support body 210, the flip frame 220 contacts and presses down the locking protrusion 2411, so that the locking member 241 moves, such as along Figure 6 When the flip frame 220 falls into place in the positive direction of the middle Z axis, the locking member 241 is reset under the action of the second elastic member 242, so that the locking protrusion 2411 is inserted into the locking groove 224 and locked.

[0102] It should be noted that a guide slope or spherical surface needs to be provided on the side of the locking protrusion 2411 facing the flip frame 220 or on the side of the flip frame 220 facing the locking protrusion 2411 to facilitate the movement of the locking member 241 to achieve locking. Figure 6 As shown, a guiding slope is provided on the side of the locking protrusion 2411 that faces upward and toward the turning frame 220 .

[0103] In addition, in order to make the locking force more balanced, locking assemblies 240 can be provided on both sides of the front end of the support body 210 to lock both sides of the flip frame 220 at the same time.

[0104] To reduce the impact of a fall when the tilt frame 220 falls, in this embodiment, the locking assembly 240 further includes a buffer 243 connected to the support body 210. When the tilt frame 220 is deflected toward the front of the support body 210, so that the connecting portion 221 is in the forward position, the tilt frame 220 abuts against the buffer 243. Thus, the buffer 243 effectively reduces the impact of the tilt frame 220.

[0105] For example, Figure 3 、 Figure 4As shown, the buffer members 243 can be soft rubber pads, silicone pads, etc., and can be installed on both sides of the front end of the support body 210 so that when the flip frame 220 falls into place, it contacts the buffer members 243 to achieve vibration reduction. Of course, the buffer members 243 can also be replaced by other components or mechanisms with vibration reduction functions, and this embodiment is not too restrictive.

[0106] In order to further isolate the impact caused by the unevenness of the runway, in this embodiment, the sliding unit 200 may further include a sliding base 250, which is slidably connected to the track 100. The support body 210 is connected to the sliding base 250, and a flexible member 251 is provided at the connection between the support body 210 and the sliding base 250.

[0107] Specifically, combined Figure 2 、 Figure 7 As shown, the sliding base 250 can be slidably set inside the track 100, one side of the sliding base 250 can be connected to the traction rope 110 inside the track 100, and the support body 210 can be connected to the sliding base 250 through a pin shaft, etc., so as to drive the support body 210 to slide through the sliding base 250.

[0108] Among them, the flexible part 251 is used to accommodate the smaller relative displacement between the support body 210 and the sliding base 250. The flexible part 251 can be a silicone sleeve, a silicone pad, a rubber sleeve, a rubber pad, etc., which can transmit the power of the sliding base 250 to the support body 210 and can accommodate the relatively small displacement of the support body 210. No excessive restrictions are made in this embodiment.
