Description

Technical Field

[0001] The invention belongs to the field of vehicle facilities and safety technology, and in particular relates to an escape window and an integrated linkage locking and limiting mechanism thereof. Background Art

[0002] Heavy vehicles (e.g., armored vehicles) are usually equipped with escape windows on the top of the vehicle body. In emergency situations, such as emergency rescue, if the vehicle is deformed due to a malfunction or collision and the door cannot be opened, the people inside the vehicle body can escape through the escape window set on the top of the vehicle. For heavy vehicles, traditional escape windows are mostly formed or welded from steel, which are heavy and require a large thrust to open the escape window. In addition, the locking mechanism and the limiting mechanism are generally set separately, which is cumbersome to operate. It usually takes a large force or multiple people to cooperate to open the escape window and safely limit it, which will delay the escape time in a crisis. In addition, the locking mechanism and the limiting mechanism are set separately, which is complex in structure, occupies effective space, has a high failure rate, and is inconvenient to use.

[0042] The escape windows on existing heavy vehicles usually have a locking mechanism and a limiting mechanism separately arranged, which has the disadvantages of complicated operation and poor safety. In order to solve the above problems, the present invention provides an escape window and an integrated linkage locking and limiting mechanism thereof. The integrated linkage locking and limiting mechanism integrates the locking mechanism and the limiting mechanism, and cooperates with a hinge mechanism provided with a torsion spring. Only a small force is required to simultaneously open and automatically limit the heavier escape window. During the limiting process, no human intervention is required, and the operation is simple, safe and reliable.

[0043] The escape window and its integrated linkage locking and limiting mechanism of the present invention are described in detail below with reference to the accompanying drawings and examples. In the following description, different "one embodiment" or "embodiment" do not necessarily refer to the same embodiment. In addition, specific features, structures, or characteristics in one or more embodiments may be combined in any suitable form.

[0044] The escape window of heavy vehicles (such as armored vehicles) is usually set on the top of the vehicle body, such as Figure 1A , Figure 1B and Figure 1C As shown, in this embodiment, the escape window includes a window panel 02 arranged at the escape window 01 of the vehicle body, a hinge mechanism 1 arranged on the vehicle body, and an integrated linkage locking and limiting mechanism installed on the window panel 02. The window panel 02 is rotatably installed on the hinge mechanism 1, so that when the escape window is closed, the window panel 02 covers the escape window 01, and when the escape window is opened, the window panel 02 opens the escape window 01; the integrated linkage locking and limiting mechanism is respectively connected to the inner locking block 6 (see Figure 1D ), the limit stopper 2 arranged on the outside of the escape window 01 is used in conjunction with the window panel 02 to achieve the locking and limiting functions.

[0045] See also Figure 2 The hinge mechanism 1 is arranged on the top of the vehicle body around the escape window 01, and is used to connect the window panel 02 with the vehicle body, and includes a support seat 11, a fixing member 13, a rotating member 14, a torsion spring 15 and a hollow shaft 16. The support seat 11 is arranged on the top of the vehicle body around the escape window 01, the fixing member 13 is fixed on the support seat 11, the rotating member 14 is connected to the window panel 02, the hollow shaft 16 is fixed on the support seat 11, and the torsion spring 15 is arranged inside the hollow shaft 16 and its two ends are respectively connected to the fixing member 13 and the rotating member 14. In this embodiment, when the window panel 02 is in the open state, the torsion spring 15 is in a naturally unstressed state. When the window panel 02 is closed, the torsion spring 15 applies a reverse force to the window panel 02 to offset a portion of the external force applied by the window panel 02 and its own gravity, thereby avoiding impact and noise when closing the escape window; when the user needs to open the window panel 02, the rotating member 14 drives the window panel 02 to move under the action of the restoring elastic force of the torsion spring 15 in the hinge mechanism 1, so that the window panel 02 rotates around the hollow shaft 16 driven by the torsion spring 15, thereby realizing that the escape window can be opened with only a small starting torque, which is more convenient and reliable to use.

[0046] In one embodiment, the hinge mechanism 1 is connected to the window panel 02 via a connecting member 12, the connecting member 12 includes a main body portion and at least two connecting plates integrally connected to the main body portion, the main body portion is fixed on the window panel 02, the two connecting plates are sleeved on the hollow shaft 16 and can rotate around the hollow shaft 16, one of the connecting plates is fixed together with the rotating member 14, and the connecting member 12 can rotate around the hollow shaft 16 synchronously with the window panel 02.

[0047] The hinge mechanism 1 is further provided with a first mounting plate 17 and a second mounting plate 18, see Figure 1B and Figure 2The first mounting plate 17 and the second mounting plate 18 are fixed on the support seat 11 at a distance, and mounting holes are symmetrically opened on the first mounting plate 17 and the second mounting plate 18. The two ends of the hollow shaft 16 are respectively passed through and fixed in the mounting holes of the first mounting plate 17 and the second mounting plate 18, and the fixing member 13 is fixed to the outside of the first mounting plate 17; the end of the hollow shaft 16 extends out of the mounting hole of the second mounting plate 18, and the rotating member 14 is located on the outside of the second mounting plate 18. The torsion spring 15 (for example, a sheet torsion spring) installed on the fixing member 13 and the rotating member 14 is passed through the inside of the hollow shaft 16; the first connecting plate and the second connecting plate are respectively provided on both sides of the connecting member 12, the first connecting plate is sleeved on the hollow shaft 16 located on the inner side of the first mounting plate 17, the second connecting plate is sleeved on the hollow shaft 16 between the second mounting plate 18 and the rotating member 14, and the second connecting plate is fixedly connected to the rotating member 14.

[0048] Preferably, the above-mentioned hinge mechanism 1 is provided with two hinge mechanisms 1, and the two hinge mechanisms 1 are symmetrically arranged. The two symmetrically arranged hinge mechanisms 1 serve as backup for each other, making the use of the escape window safer and more reliable.

[0049] In order to achieve the locking and opening limit of the window panel 02, the escape window of the present invention is also provided with an integrated linkage locking limit mechanism and a limit stopper 2 and an inner locking block 6 used in conjunction with the same. The integrated linkage locking limit mechanism is arranged on the window panel 02, and the limit stopper 2 is arranged on the support seat 11 (see Figure 2 ), the inner locking block 6 is arranged on the inner side of the top of the vehicle body (see Figure 1D ), the integrated linkage locking limit mechanism cooperates with the limit block 2 to realize the limited opening of the window panel 02, and the integrated linkage locking limit mechanism cooperates with the inner locking block 6 to realize the locking and closing of the window panel 02.

[0050] See also Figure 3 The integrated linkage locking limit mechanism includes an outer limit mechanism 3, an inner locking mechanism 4 and a linkage mechanism 5. The outer limit mechanism 3 and the inner locking mechanism 4 have basically the same structure. The two are connected as a whole through the linkage mechanism 5, wherein:

[0051] The outer limit mechanism 3 includes an outer bolt assembly 31, an outer return spring 32, an outer guide groove 33, and a limit block 2 for use with the outer bolt assembly 31. The outer bolt assembly 31 can be slidably inserted into the outer guide groove 33 with an outer guide channel. The outer guide groove 33 is fixed on the window plate 02 and its outer guide channel faces the limit block 2. The outer guide groove 33 guides the outer bolt assembly 31. Specifically, the outer bolt assembly 31 includes an outer bolt 311 and an outer threaded rod 312 connected in one piece. The outer return spring 32 is inserted into the outer threaded rod 312 and is limited in the outer guide channel of the outer guide groove 33. The outer return spring 32 always applies an outward thrust to the outer bolt 311 of the outer bolt assembly 31. When the window plate 02 rotates to the right position, due to the guiding effect of the outer guide groove 33, the outer return spring 32 pushes the outer bolt 311 into the limit groove 21 of the limit block 2 without the action of external force, so as to stabilize the limit.

[0052] In another embodiment, an external adjusting nut 535 is provided on the external threaded rod 312 of the external locking tongue assembly 31, and the external adjusting nut 535 is located between the external return spring 32 and the external pull rod assembly 533 (that is, the external adjusting nut 535 is located on the external threaded rod 312 extending out of the external guide groove 33). By adjusting the position of the external adjusting nut 535 relative to the external threaded rod 312, the restoring elastic force of the external return spring 32 can be adjusted.

[0053] The inner locking mechanism 4 includes an inner lock tongue assembly 41, an inner return spring 42, an inner guide groove 43 and an inner locking block 6 for cooperating with the inner lock tongue assembly 41. The inner lock tongue assembly 41 can be slidably inserted into the inner guide groove 43 with an inner guide channel. The inner guide groove 43 is fixed on the window panel 02 and its inner guide channel is directly opposite to the inner locking block 6. The inner guide groove 43 guides the inner lock tongue assembly 41. Specifically, the inner lock tongue assembly 41 includes an inner lock tongue 411 and an inner threaded rod 412 that are integrally connected. The inner return spring 42 is inserted into the inner threaded rod 412 and is limited in the inner guide channel of the inner guide groove 43. The inner return spring 42 always applies an outward thrust to the inner lock tongue 411 of the inner lock tongue assembly 41. When the window panel 02 is closed, due to the guiding effect of the inner guide groove 43, in the absence of external force, the inner return spring 42 pushes the inner locking tongue 411 into the locking groove 61 of the inner locking block 6 for safe locking.

[0054] Preferably, the inner lock tongue 411 is a wedge-shaped structure, and its lower side surface is an upward curved surface, so that the inner lock tongue 411 can easily extend into the locking groove 61 provided in the inner locking block 6. Even if there is some deviation between the inner lock tongue 411 and the locking groove 61, due to the guiding effect of the lower curved surface of the inner lock tongue 411, the inner lock tongue 411 can also be smoothly inserted into the locking groove 61.

[0055] Similarly, in another embodiment, an internal adjusting nut 545 is provided on the internal threaded rod 412 of the internal locking tongue assembly 41, and the internal adjusting nut 545 is located between the internal return spring 42 and the internal pull rod assembly 543 (that is, the internal adjusting nut 545 is located on the internal threaded rod 412 extending out of the inner guide groove 43). By adjusting the position of the internal adjusting nut 545 relative to the internal threaded rod 412, the restoring elastic force of the internal return spring 42 can be adjusted.

[0056] The linkage mechanism 5 is provided with a rotating shaft assembly 51, which at least includes a rotating shaft 511. The rotating shaft 511 can be rotatably penetrated on the window panel 02. The upper end of the rotating shaft 511 is equipped with an external linkage assembly 53 connected to the external limit mechanism 3, and the lower end of the rotating shaft 511 is equipped with an internal linkage assembly 54 connected to the internal locking mechanism 4. The rotation of the rotating shaft 511 can simultaneously drive the outer lock tongue 311 and the inner lock tongue 411 to retract through the external linkage assembly 53 and the internal linkage assembly 54 to separate and unlock from the limit block 2 or the internal locking block 6.

[0057] In another embodiment, the rotating shaft assembly 51 also includes a sleeve 512 installed on the rotating shaft 511, an upper limit plate 513 is provided on the upper end of the sleeve 512, and a lower limit plate 514 is installed on the lower end of the rotating shaft 511. The window panel 02 is passed through the rotating shaft 511 and limited between the upper limit plate 513 and the lower limit plate 514. The upper end and the lower end of the rotating shaft 511 extending out of the window panel 02 are both square.

[0058] Specifically, the external linkage assembly 53 is installed on the upper surface of the window panel 02, and includes an external rotating plate 531, an external connecting rod 532 and an external pull rod assembly 533. The external rotating plate 531 is fixed to the upper end of the rotating shaft 511, and the two ends of the external connecting rod 532 are respectively hinged to the external rotating plate 531 and the external pull rod assembly 533. The external pull rod assembly 533 is threadedly connected to the external threaded rod 312 of the external lock tongue assembly 31.

[0059] Preferably, the middle portion of the outer tie rod assembly 533 can be slidably inserted into the outer guide block 534 , and the outer guide block 534 is fixed on the window panel 02 to guide the outer tie rod assembly 533 .

[0060] The inner linkage assembly 54 is installed on the lower surface of the window panel 02, and includes an inner rotating plate 541, an inner connecting rod 542 and an inner pull rod assembly 543. The inner rotating plate 541 is fixed to the lower end of the rotating shaft 511, and the two ends of the inner connecting rod 542 are respectively hinged to the inner rotating plate 541 and the inner pull rod assembly 543. The inner pull rod assembly 543 is threadedly connected to the internal threaded rod 412 of the inner lock tongue assembly 41.

[0061] Preferably, the middle portion of the inner tie rod assembly 543 can be slidably inserted into the inner guide block 544 , and the inner guide block 544 is fixed on the window panel 02 to guide the inner tie rod assembly 543 .

[0062] The working process of the integrated linkage locking limit mechanism is as follows:

[0063] By rotating the rotating shaft 511 (i.e. applying a rotational torque to the rotating shaft 511), the outer rotating plate 531 and the inner rotating plate 541 are driven to rotate at the same time, and the outer pull rod assembly 533 is pulled by the outer connecting rod 532 and the inner connecting rod 542 pulls the inner pull rod assembly 543, thereby driving the outer lock tongue assembly 31 to compress the outer return spring 32 and the inner lock tongue assembly 41 to compress the inner return spring 42, so that the outer lock tongue 311 retracts into the outer guide groove 33 and the inner lock tongue 411 retracts into the inner guide groove 43; when no rotational torque is applied to the rotating shaft 511, the outer lock tongue 311 of the outer lock tongue assembly 31 extends out of the outer guide groove 33 under the action of the self-restoring force (elastic force) of the outer return spring 32, and the inner lock tongue 411 of the inner lock tongue assembly 41 extends out of the inner guide groove 43 under the action of the self-restoring force (elastic force) of the inner return spring 42. At the same time, the outer rotating plate Under the elastic force of the external return spring 32, 531 returns to a state coaxial with the external pull rod assembly 533, and under the elastic force of the internal return spring 42, the internal rotating plate 541 returns to a state coaxial with the internal pull rod assembly 543. At this time, if the window panel 02 covers the escape window 01, the external lock tongue 311 extends out of the internal guide groove 43 under the action of the external return spring 32, and the internal lock tongue 411 extends out of the internal guide groove 43 under the action of the internal return spring, and extends into the locking groove of the internal locking block 6, thereby realizing the safe locking of the window panel 02; if the window panel 02 rotates around the hollow shaft 16 to open to the limiting groove 21 of the limiting block 2, the external lock tongue 311 extends into the limiting groove 21 of the limiting block 2 under the action of the external return spring 32, thereby realizing the stable limiting of the window panel 02, and the internal lock tongue 411 extends out of the internal guide groove 43 under the action of the internal return spring 42.

[0064] When in use, by rotating the rotating shaft 511 (i.e. applying a rotational torque to the rotating shaft 511), the inner locking mechanism 4 and the outer limiting mechanism 3 simultaneously produce a linkage effect, i.e. the inner locking tongue 411 and the outer locking tongue 311 simultaneously retract into their respective guide grooves; without applying any rotational torque to the rotating shaft 511, when the window panel 02 is closed, the inner locking tongue 411 extends out of the inner guide groove 43 under the action of the inner return spring 42, and extends into the locking groove 61 of the corresponding inner locking block 6, thereby achieving safe locking of the window panel 02, while the outer locking tongue 311 extends out of the outer guide groove 33 under the action of the outer return spring 32; when the window panel 02 is fully opened, the inner locking tongue 411 extends out of the inner guide groove 43 under the action of the inner return spring 42, and the outer locking tongue 311 extends out of the outer guide groove 33 under the action of the outer return spring 32, and extends into the limiting groove 21 of the corresponding limiting block 2, thereby achieving stable limiting of the window panel 02.

[0065] As a further optimization of the above embodiment, the linkage mechanism 5 is further provided with a handle 52, which is installed at the lower end of the rotating shaft 511, so that the personnel in the vehicle can open the escape window. The operator applies a rotation torque to the rotating shaft 511 through the handle 52, and at the same time, applies a push or pull force to the window panel 02, so that the window panel 02 can be easily opened / closed. Due to the effect of the torsion spring 15 in the hinge mechanism 1 connecting the window panel 02 to the vehicle body, the window panel 02 can be opened by applying a small force to the window panel 02.

[0066] Preferably, the limit groove 21 is arranged at the top of the limit block 2, and the stable limit state of the window panel 02 is an upright state, that is, the window panel 02 is basically perpendicular to the top of the vehicle body. At this time, the torsion spring 15 in the hinge mechanism 1 is in a stress-free state. Since the outer lock tongue 311 is basically not affected by the weight of the window panel 02, the integrated linkage locking limit mechanism is safer and more durable.

[0067] In another embodiment, a keyhole 7 is provided on the top of the rotating shaft 511, which is used in conjunction with an L-shaped wrench. The lever principle is used to rotate the L-shaped wrench matching the keyhole 7, thereby rotating the rotating shaft 511 to open the window panel 02 from the outside.

[0068] Preferably, a window frame is provided around the escape window 01, and a sealing ring (for example, a rubber ring) is provided around the window frame, or a sealing ring is provided around the window panel 02, and the sealing ring is located at the joint between the window frame and the window panel 02. When the window panel 02 is covered on the window frame, the sealing ring plays a sealing role to prevent rainwater or dust from entering the vehicle compartment through the joint between the window frame and the window panel 02.

[0069] Obviously, the application of the integrated linkage locking and limiting mechanism and its accessories of the present invention is not limited to the above-mentioned embodiments, and can also be applied to other occasions as an independent component, such as locking and limiting the rear doors of military vehicles such as armored vehicles.

[0070] Those skilled in the art should understand that these embodiments are only used to illustrate the present invention but not to limit the scope of the present invention, and various equivalent variations and modifications made to the present invention belong to the disclosure of the present invention.
