Description

Technical Field

[0001] This invention relates to the field of vehicle evacuation technology, and in particular to a vehicle evacuation release device and release method. Background Technology

[0002] During vehicle swivel tests, emissions tests, or other dynamic tests, vehicles are typically secured to a predetermined position on a test bench (such as a swivel) using fixed chains or tethers. In the event of an emergency during the test (such as a vehicle fire, battery thermal runaway, or equipment failure) requiring immediate evacuation, the fixed chains must be released quickly and the vehicle pulled away from the danger zone.

[0003] Current fixed release methods mainly rely on manual disassembly or the use of a single locking mechanism controlled by electromagnetic or pneumatic forces. However, traditional automated release devices are often complex in structure and are prone to failure in extreme environments such as high temperatures and smoke due to electronic component malfunctions or damage to the pneumatic circuit. Summary of the Invention

[0004] In this section, as well as in the abstract and title of this application, some simplifications or omissions may be made to avoid obscuring the purpose of this section, the abstract, and the title of this application, and such simplifications or omissions shall not be used to limit the scope of the invention.

[0005] To address the shortcomings of existing technologies, one objective of this invention is to provide a vehicle evacuation release device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a vehicle evacuation release device, comprising a first connecting member, one end of which is disposed on a fixed latch; a second connecting member, one end of which is disposed on a rotating latch, and the other end of which is rotatably connected to the first connecting member; a fixing member, detachably disposed between the first connecting member and the second connecting member, for restricting the relative rotation of the first connecting member and the second connecting member; and a traction rope having a first connecting end A and a second connecting end B, the first connecting end A being connected to the first connecting member and the second connecting end B being connected to the fixing member; wherein, the traction rope is configured such that, under stress, the second connecting end B first drives the fixing member to disengage, thereby releasing the restriction on the first connecting member and the second connecting member, and then the first connecting end A drives the first connecting member to rotate.

[0007] As a preferred embodiment of the vehicle evacuation release device of the present invention, the first connecting member has: a first extension that extends in a horizontal direction; a second extension that extends upward at one end of the first extension; and a third extension that extends from the upper end of the second extension in a direction opposite to the first extension.

[0008] As a preferred embodiment of the vehicle evacuation release device of the present invention, the second connecting member has: a fourth extension that extends in a vertical direction; and a fifth extension that extends to one side at one end of the fourth extension; wherein the extension angle C of the fifth extension is the same as the extension angle D of the second extension.

[0009] In a preferred embodiment of the vehicle evacuation release device of the present invention, the rotating latch includes a first latch portion with a thickness equal to that of the fixed latch and a second latch portion with a thickness less than that of the fixed latch.

[0010] As a preferred embodiment of the vehicle evacuation release device of the present invention, the fixed latch has a spatial groove with the same thickness as the second latch portion, one end of the first extension portion is rotatably disposed in the spatial groove, and the second connector is disposed outside the spatial groove.

[0011] As a preferred embodiment of the vehicle evacuation release device of the present invention, the fixed latch is provided with a groove that is adapted to the fifth extension.

[0012] As a preferred embodiment of the vehicle evacuation release device of the present invention, the fixing member includes a first pin, one end of which passes through the second extension and the fourth extension in sequence and extends to the outside; and a second pin, one end of which passes through the first pin, and the other end of which is connected to the second connecting end B of the traction rope.

[0013] As a preferred embodiment of the vehicle evacuation release device of the present invention, it further includes a housing, which is fixedly mounted on the fixed latch by bolts; the first pin is mounted on the bolt by an anti-detachment rope, and a spring is provided on the first pin.

[0014] In a preferred embodiment of the vehicle evacuation release device of the present invention, the traction rope includes a rope sleeve disposed on the housing, a rope core disposed within the rope sleeve, one end of the rope core being disposed at the end of the third extension, and the other end of the rope core being connected to the cylinder.

[0015] To address the shortcomings of existing technologies, another objective of this invention is to provide a method for vehicle detachment and release.

[0016] The present invention adopts the following technical solution: a vehicle evacuation and release method, which is operated according to the following steps: The drive cylinder pulls the rope core, and the second connecting end B of the rope core under force drives the fixing member to disengage, thereby releasing the relative rotation restriction between the first connecting member and the second connecting member.

[0017] The first connector is continuously driven to rotate relative to the second connector through the first connecting end A of the rope core, causing the fixed lock to separate from the rotating lock and releasing the vehicle's fixed chain.

[0018] After the vehicle's fixed chain is released, the drive winch moves the vehicle along a preset track to a safe area.

[0019] The vehicle release release device of the present invention has the following advantages: By cleverly arranging the first and second connecting ends of the traction rope, the present invention utilizes only the travel difference of the traction rope under stress to achieve a two-stage action: first releasing the rotation restriction, then driving the lock to disengage. This purely mechanical linkage design avoids the signal delay or failure that may occur in electronic logic components under extreme environments such as high temperature and dense smoke, ensuring the absolute reliability of the release action.

[0033] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0034] The terminology used in this invention is that which is currently widely used in the art in consideration of the function of the invention; however, these terms may vary according to the intent of those skilled in the art, precedent, or new technology in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the invention. Therefore, the terminology used in this specification should not be construed as simple names, but rather based on the meaning of the terms and the overall description of the invention.

[0035] Reference Figure 1 This embodiment provides a vehicle evacuation release device, including a first connector 100, a second connector 200, a fixing member 300, a traction rope 400, a fixed lock 500, and a rotating lock 600.

[0036] One end of the first connecting member 100 is mounted on the fixed locking buckle 500. One end of the second connecting member 200 is mounted on the rotating locking buckle 600, and the other end is rotatably connected to the first connecting member 100. The fixing member 300 is detachably disposed between the first connecting member 100 and the second connecting member 200 to restrict the relative rotation of the first connecting member 100 and the second connecting member 200. The traction rope 400 has a first connecting end A and a second connecting end B. The first connecting end A is connected to the first connecting member 100, and the second connecting end B is connected to the fixing member 300. The traction rope 400 is configured such that, under stress, the second connecting end B first drives the fixing member 300 to disengage, thereby releasing the restriction on the first connecting member 100 and the second connecting member 200, and then the first connecting end A drives the first connecting member 100 to rotate.

[0037] Specifically, one end of the first connecting member 100 is rotatably connected to the fixed latch 500, and the first connecting member 100 can be rotated by pulling the other end. One end of the second connecting member 200 is rotatably connected to the first connecting member 100, and the other end of the second connecting member 200 is rotatably connected to the rotary latch 600. By pulling the end of the first connecting member 100, the first connecting member 100 rotates, which in turn drives one end of the second connecting member 200 to rotate, and the other end of the second connecting member 200 rotates accordingly. At the same time, the other end of the second connecting member 200 drives the rotary latch 600 to rotate, thereby separating the rotary latch 600 from the fixed latch 500.

[0038] The first connector 100 constitutes the active power input component of the device. The rotational connection point between the first connector 100 and the fixed latch 500 forms a first fulcrum, and the rotational connection point between the first connector 100 and the second connector 200 forms a second fulcrum. The second connector 200 serves as an intermediate transmission rod, with its two ends connected to the active side (first connector 100) and the driven side (rotational latch 600) respectively, forming a linkage mechanism.

[0039] When the first connecting end A of the traction rope 400 generates tension and acts on the end of the first connecting member 100, the first connecting member 100 rotates about its first fulcrum on the fixed buckle 500. This rotation is transmitted to the second connecting member 200 via the second fulcrum and is converted into the displacement of the second connecting member 200. Subsequently, the other end of the second connecting member 200 drives the rotating buckle 600 to rotate about its own rotation center axis, so that the rotating buckle 600 and the fixed buckle 500 switch from an engaged state to a fully open state, thereby reliably releasing the vehicle fixing chain hooked between them.

[0040] To achieve the "unlock first, then rotate" timing logic in this embodiment, the physical length of the traction rope 400 and the distance between each connection point are configured such that, in the initial locked state, the connecting line segment between the first connecting end A and the second connecting end B is in a slack state (with slack), while the connecting line segment between the second connecting end B and the fixing member 300 is in a taut or nearly taut state.

[0041] When the traction power is activated, the effective stroke generated by the traction rope 400 first acts on the second connecting end B, pulling the fixing member 300, which acts as a limit pin, out of the limiting holes of the first connecting member 100 and the second connecting member 200. At this time, the first connecting end A is still absorbing its slack and has not yet generated a driving force on the first connecting member 100. Only when the fixing member 300 is completely disengaged and the mechanical restriction is released, does the traction rope 400 continue to stretch until the slack of the first connecting end A is exhausted, and only then does the pulling force begin to drive the first connecting member 100 to rotate. Through the structural configuration of length redundancy difference, the reliable sequence of tripping and linkage opening is ensured from a physical perspective.

[0042] Through the above-described configuration, the lever arm formed by the first connecting member 100 can effectively overcome the frictional force of the rotating lock 600 when subjected to the enormous tension of the vehicle chain. Simultaneously, the fully mechanical step-by-step action logic greatly simplifies the complexity of the control system. In scenarios requiring high response speed, such as vehicle fire evacuation, the two originally independent process steps of "pin unlocking" and "linkage unlocking" can be automatically completed with a single continuous traction action, significantly shortening evacuation preparation time and avoiding disengagement failures caused by misoperation or electrical faults.

[0043] Reference Figure 2 The first connector 100 has a first extension 101, a second extension 102 and a third extension 103.

[0044] The first extension 101 extends horizontally. The second extension 102 extends upward at one end of the first extension 101. The third extension 103 extends from the upper end of the second extension 102 in the opposite direction to the first extension 101.

[0045] The starting end of the first extension 101 is rotatably connected to the fixed lock 500. The end of the first extension 101 (the starting end of the second extension 102) is rotatably connected to one end of the second connector 200. The end of the second extension 102 (the starting end of the third extension 103) is provided with a pin hole through which the fixing member 300 passes. The end of the third extension 103 is used to connect the first connecting end A of the traction rope 400.

[0046] In this embodiment, the geometry of the first connector 100 is specially configured such that, in the initial state of the rotating latch 600 being closed and locked, the first extension 101 extends downward at an angle relative to the horizontal plane, the second extension 102 extends to the right from the end of the first extension 101, and the third extension 103 extends downward again at an angle.

[0047] The above layout provides significant space for motion compensation during subsequent release actions. Since the end of the third extension 103 (i.e., the point of force of the first connecting end A of the traction rope) is in a low spatial position in the initial state, the first connecting member 100 can obtain a large rotational stroke when the traction rope 400 provides an upward pulling force.

[0048] Compared to the straight or simple obtuse-angle structure in which the third extension 103 continues to extend upward along the direction of the second extension 102, the present invention, through this folding design, allows the first connector 100 to smoothly transition from the initial downward tilt position to a horizontal extension when subjected to an upward traction force (at this time, the first extension 101 is in the horizontal direction, the second extension 102 is tilted upward, and the third extension 103 extends in the opposite direction).

[0049] This process ensures that the effective rotation angle of the first connector 100 is greater than 60°. This ensures that the rotating latch 600 can be driven to the fully open position via the linkage mechanism, so that the gap between the fixed latch 500 and the rotating latch 600 is sufficient to allow the heavy vehicle chain to slide down without obstruction.

[0050] Reference Figure 3 The second connector 200 serves as a transmission intermediary connecting the active drive unit (first connector 100) and the actuator (rotation lock 600), and has a fourth extension 201 and a fifth extension 202, which together constitute an L-shaped or bent transmission arm structure.

[0051] Specifically, when the rotary latch 600 is in the closed locking state: the fourth extension 201 extends vertically, and its starting end (bottom end) is rotatably connected to the rotary latch 600. A pin hole for the fastener 300 to pass through is provided at the end (top) of the fourth extension 201. The fifth extension 202 extends horizontally to one side from the end of the fourth extension 201, and its end coincides spatially with the end of the first extension 101 (i.e., the intersection of the first extension 101 and the second extension 102), and is rotatably connected by a rotating shaft.

[0052] In this embodiment, this specific spatial arrangement produces a key technical effect: coaxial locking in the initial state. Since the second extension 102 of the first connector 100 has a pin hole at its end, and the fourth extension 201 of the second connector 200 also has a pin hole at its end, when the latch 600 is closed by rotation, these two pin holes are spatially aligned and in a coaxial state. At this time, the fixing member 300 (such as a locking pin) can simultaneously pass through both pin holes.

[0053] When the traction rope 400 pulls the first connector 100 upward to rotate: since the ends of the first extension 101 and the fifth extension 202 are rotatably connected, the upward swing of the first connector 100 will generate an upward component force acting on the second connector 200 through this connection point. Because the fourth extension 201 extends in the vertical direction, this upward component force is efficiently converted into a tangential force that drives the rotating latch 600 to rotate.

[0054] With the second connector 200, the vertical fourth extension 201 ensures that the driving force can be transmitted to the rotary latch 600 with the shortest path and the most direct torque.

[0055] Reference Figure 4 The extension angle C of the fifth extension 202 is the same as the extension angle D of the second extension 102.

[0056] In this embodiment, the extension angle C of the fifth extension 202 and the extension angle D of the second extension 102 are configured to have the same value. Although the extension directions of the two are different due to the overall configuration requirements, the precise definition of the angle values ​​ensures that the second extension 102 and the fifth extension 202 remain parallel to each other in spatial arrangement.

[0057] Since the second extension 102 (active side lever arm) is parallel to the fifth extension 202 (driven side transmission arm), when the first connecting member 100 is pulled upward, the pulling force is transmitted through the overlapping rotational connection point of the first connecting member 100 and the second connecting member 200 (i.e., the end of the fifth extension 202). The parallel structure ensures that the transmission ratio remains relatively constant from the initial stage of rotation to the large-angle opening stage, effectively avoiding the problem of excessive instantaneous resistance caused by drastic changes in the lever arm angle.

[0058] Reference Figure 5 The rotating latch 600 includes a first latch part 601 with a thickness equal to that of the fixed latch 500 and a second latch part 602 with a thickness less than that of the fixed latch 500.

[0059] The first locking part 601 serves as the main hook force-bearing part, and its thickness is consistent with that of the fixed locking part 500. Thus, in the closed state, the opposite sides of the first locking part 601 and the fixed locking part 500 are in the same plane, ensuring that the force-bearing surface is flat when locking the vehicle chain.

[0060] The thickness of the second locking portion 602 is configured to be less than that of the first locking portion 601, thereby forming a stepped embedding space on one side of the rotating locking 600. Two sets of rotating holes are provided on the second locking portion 602. The first set of rotating holes is used to achieve a reference rotational connection with the fixed locking 500; the second set of rotating holes is used to connect with the starting end of the fourth extension 201 of the second connecting member 200. Since both sets of holes are provided on the thinner second locking portion 602, all rotational fulcrums are integrated within the same functional area. In this embodiment, the thickness difference between the first locking portion 601 and the second locking portion 602 is precisely set to be equal to (or slightly greater than) the thickness of the second connecting member 200.

[0061] Because the second connector 200 is nested within the stepped space provided by the second locking part 602, the outer surface of the second connector 200 can be substantially aligned with the outer surface of the first locking part 601. This structure ensures that when the traction force is transmitted through the second connector 200 to the rotating locking 600, its line of action is as close as possible to the central force-bearing plane of the locking, effectively avoiding eccentric loads caused by lateral installation. This design hides the thickness of the second connector 200 within the total thickness range of the rotating locking 600. This embedded installation method greatly reduces the lateral width of the release device.

[0062] Furthermore, with the horizontal line passing through the first set of rotating holes (i.e., the connection fulcrum between the rotating latch 600 and the fixed latch 500) as the baseline, the second set of rotating holes (i.e., the connection point between the rotating latch 600 and the second connector 200) is specifically arranged below the baseline.

[0063] If the two sets of holes are on the same horizontal line, they are very likely to enter the "dead point" position (i.e., the driving force line passes through the center of rotation) during rotation, causing the mechanism to jam. By moving the second set of holes downward, the power input point and the rotation fulcrum always maintain a certain vertical phase difference in space.

[0064] Reference Figure 6 The fixed latch 500 is not a simple flat plate structure, but rather a precise spatial cut and functional partitioning for the movement path of the linkage mechanism.

[0065] The fixed latch 500 has a space groove 501 with the same thickness as the second latch part 602. One end of the first extension part 101 is rotatably disposed in the space groove 501, and the second connector 200 is disposed outside the space groove 501.

[0066] Specifically, a space groove 501 is provided on one side of the fixed latch 500, and the depth of the space groove 501 is configured to be the same as the thickness of the second latch portion 602 of the rotating latch 600.

[0067] The starting end of the first extension 101 is fully embedded in the space groove 501 and connected to the fixed latch 500 via a rotating shaft. The embedded rotating connection ensures that the stress point of the first connector 100 is located in the center region of the thickness of the fixed latch 500 during rotation, which greatly enhances the shear strength of the rotating fulcrum.

[0068] The locking buckle 500 has a groove 502 that matches the fifth extension 202. When the rotating locking buckle 600 is in the closed locking state, since the second extension 102 is parallel to the fifth extension 202 and is at a lower position, the fifth extension 202 can be smoothly inserted into the groove 502.

[0069] Reference Figure 7 The fastener 300 includes a first pin 301 and a second pin 302.

[0070] One end of the first pin 301 passes through the second extension 102 and the fourth extension 201 in sequence and extends to the outside. One end of the second pin 302 passes through the first pin 301, and the other end of the second pin 302 is connected to the second connecting end B of the traction rope 400.

[0071] The first pin 301, as the main component restricting the rotation of the mechanism, has one end passing through the pin holes of the aligned second extension 102 and the fourth extension 201, and extending to the outside of the fourth extension 201. The first pin 301 forms a double shear constraint surface by spatially spanning the junction of the first connector 100 and the second connector 200. Even if the vehicle evacuation device is subjected to strong impact or vibration, the first pin 301 ensures that there is no relative displacement between the first connector 100 and the second connector 200.

[0072] The first pin 301 has a radial through hole through which the second pin 302 passes, and the through hole is located near its end extending to the outside.

[0073] The second pin 302 acts as a safety pin, with one end perpendicularly penetrating the radial through hole of the first pin 301. The other end of the second pin 302 is reliably connected to the second connecting end B of the traction rope 400. Since the second pin 302 is located in the path of the first pin 301, in the initial state, even if the first pin 301 is subjected to a lateral thrust, the first pin 301 cannot slide out of the pin holes of the second extension 102 and the fourth extension 201 due to the obstruction of the second pin 302.

[0074] The force on the traction rope 400 is first transmitted to the second pin 302. At the moment the release action is initiated, the traction rope drives the second pin 302 to be pulled out of the first pin 301 first, thereby releasing the axial constraint on the first pin 301.

[0075] The second pin 302 is made of a material with a certain elasticity and is U-shaped. One end of the second pin 302 passes through the first pin 301, and the other end is W-shaped with the bottom of the U-shape of the second pin 302, so that the outer surface of the first pin 301 can be inserted into the W-shaped bend of the second pin 302. The bottom of the U-shape of the second pin 302 is connected to the second connecting end B of the traction rope 400. When the traction rope 400 is under force, the traction rope 400 pulls the bottom of the U-shape of the second pin 302, causing the second pin 302 to open and disengage from the first pin 301, thereby releasing the restriction on the first pin 301.

[0076] Reference Figure 8This embodiment provides a vehicle evacuation release device, which also includes a housing 700.

[0077] The housing 700 is fixedly mounted on the locking buckle 500 by bolts 701. The first pin 301 is mounted on the bolt 701 by an anti-detachment rope 702, and a spring 301a is mounted on the first pin 301.

[0078] The housing 700 encloses the first connector 100, the second connector 200, and the main body of the linkage mechanism, effectively preventing debris, dust, or soot from vehicle fires in the laboratory environment from entering the linkage mechanism, thus ensuring the cleanliness and smooth operation of the precision mechanical parts.

[0079] The walls of the housing 700 provide auxiliary support for the routing of the traction rope 400 and the limiting of the fixing component 300, thereby improving the overall appearance and reliability of the device.

[0080] The first pin 301 is attached to the bolt 701 by a flexible anti-disengagement rope 702. During the release process, once the first pin 301 is fully pulled out of the pin hole, it will hang within a predetermined range near the housing 700 due to the traction restraint of the anti-disengagement rope 702. Operators can quickly retrieve the locking pin and reset the device, greatly improving maintenance efficiency.

[0081] A spring 301a (preferably a compression spring) is fitted onto the first pin 301. One end of the spring 301a abuts against the head or retaining ring of the first pin 301, and the other end abuts against the outer wall of the housing 700 or the first connector 100.

[0082] During initial assembly, the spring 301a is in a compressed state, and the elastic force of the spring 301a can assist the first pin 301 to pop out automatically.

[0083] Reference Figure 9 and Figure 11 The traction rope 400 includes a rope sleeve 401 disposed on the housing 700, a rope core 402 disposed inside the rope sleeve 401, one end of the rope core 402 being disposed at the end of the third extension 103, and the other end of the rope core 402 being connected to the cylinder 800.

[0084] One end of the rope core 402 (i.e., the first connecting end A) is connected to the end of the third extension 103 of the first connector 100. The other end of the rope core 402 extends to the outside of the housing and is reliably connected to the piston rod of the cylinder 800.

[0085] Cylinder 800 serves as the power actuator for the entire tripping device, and is preferably a high-thrust double-acting cylinder or a spring-reset single-acting cylinder.

[0086] When the cylinder 800 receives the retraction command and performs the retraction action, the linear tension it generates is transmitted through the rope core 402. Since the end of the rope loop 401 is fixed to the housing, the rope core 402 will generate displacement relative to the housing inside the housing, thereby pulling the third extension 103 to rotate upward.

[0087] By utilizing the relative sliding of the rope core 402 within the rope loop 401, the time difference between "pulling the pin" and "unlocking" can be precisely controlled very easily by adjusting the initial pretension of the rope core (i.e., the aforementioned redundant length).

[0088] Reference Figure 9 and Figure 12 This embodiment provides a method for vehicle evacuation and deactivation, which is operated according to the following steps: S1, Initialize and release the first-level restriction. When the system receives the evacuation trigger signal, it first drives the cylinder 800 to move. The piston rod of the cylinder 800 retracts to generate tension, which is guided by the rope loop 401 to act on the rope core 402.

[0089] Since the first connecting end A (connecting the first connecting member 100) of the rope core 402 has a reserved redundant length, while the second connecting end B (connecting the fixing member 300) is in an instantaneous stress state, the tension is first applied to the fixing member 300.

[0090] Under stress, the second connecting end B of the rope core 402 first drives the fixing member 300 (the first pin 301 and the second pin 302) to completely disengage from the coaxial pin hole of the first connecting member 100 and the second connecting member 200. At this time, the first connecting member 100 switches from a rigid locking state to a free rotation state, successfully releasing the relative rotation restriction between the first connecting member 100 and the second connecting member 200.

[0091] S2, linkage conversion and drive the lock to separate, cylinder 800 continues to operate, rope core 402 continues to retract until the redundant length at the first connection end A is exhausted.

[0092] At this time, the first connecting end A of the rope core 402 begins to apply an upward pulling force to the third extension 103. The first connecting member 100 rotates upward about its fulcrum on the fixed latch 500 (rotation angle greater than 60°).

[0093] The first connector 100 acts as an active lever, driving the second connector 200 connected to it to move synchronously through its end. The fourth extension 201 of the second connector 200 then moves upward, pulling the rotating latch 600 to rotate around its rotating hole. Finally, the rotating latch 600 and the fixed latch 500 fully open and separate, and the vehicle fixing chain that was originally hooked between the two automatically slips off under the action of gravity or traction.

[0094] S3, execute traction evacuation. After confirming that the vehicle's fixed chain has been released (which can be detected by limit switches or sensors, or by cylinder stroke), the control system drives the winch to start.

[0095] The winch acts on the vehicle body through the traction cable, at which point the vehicle is no longer restrained by the chain.

[0096] Drive the vehicle along the pre-set track to a safe, open area. In this step, because the release mechanism has been pre-completed, mechanical damage caused by forcibly pulling the vehicle without disengaging the latch is avoided, ensuring a smooth and rapid evacuation process.

[0097] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of the present invention.
