DETAILED DESCRIPTION

[0034] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention. The specific structures and functional details disclosed herein are only used to describe the exemplary embodiments of the present invention. However, the present invention can be embodied in many alternative forms, and it should not be understood that the present invention is limited to the embodiments set forth herein.

[0035] In the use scenarios of escape windows, especially those used on military vehicles, in addition to being used in emergency situations, the escape windows can be opened during normal driving to observe the vehicle's surroundings or to perform ventilation operations. The escape windows of military vehicles are used frequently, and the operability, reliability, and maintainability of the escape windows are required to be high.

[0036] That is, the escape window also needs to have a high frequency of switching operations. Correspondingly, for the convenience of opening and closing the escape window, a limiting device should also be set between the switch components of the escape window and the escape window and the vehicle body to prevent abnormal noise caused by collision between adjacent components when driving under poor driving conditions, thereby improving driving quality and extending the service life of components.

[0037] like Figure 1-7 As shown, an escape window comprises an outer skin 1, an inner skin 2, a first anti-loosening mechanism and a second anti-loosening mechanism, wherein the circumferential surface of the inner skin 2 is connected to the inner side of the outer skin 1 so that there is an assembly gap between the inner skin 2 and the outer skin 1;

[0038] The first anti-loosening mechanism comprises:

[0039] - a sleeve 3, arranged in the assembly gap and fixed on the outer skin 1;

[0040] - a fastener 4, having a through end 41 for penetrating the inner skin 2 and cooperating with the sleeve 3, and a clamping end 42 for pressing on the inner skin 2, the through end 41 and the clamping end 42 are two ends of the fastener 4, and are used to limit the inner skin 2 from being separated from the outer skin 1;

[0041] Furthermore, the fastener 4 may be threadedly connected in the sleeve 3. Of course, the sleeve 3 and the fastener 4 may also be connected by snap fastening or the like, which will not be further described or limited here.

[0042] The second anti-loosening mechanism comprises:

[0043] - an anti-loosening sheet 5, which is installed between the pressing end 42 and the inner skin 2, and is penetrated by the penetration end 41 at the same time as the inner skin 2;

[0044] - a folding ear 6, which is arranged on the anti-loosening sheet 5 and is used to buckle on the pressing end 42 after the folding ear 6 is bent, so as to prevent the fastener 4 from falling out of the sleeve 3.

[0045] It is worth mentioning that during the assembly process, the inner skin 2 is first buckled onto the outer skin 1, and then the anti-loosening sheet 5 is placed on the inner skin 2, and the folding ear 6 is in an unbent state. At this time, the through end 41 on the fastener 4 penetrates the anti-loosening sheet 5 and the inner skin 2 in turn and then cooperates with the sleeve 3. When the through end 41 and the sleeve 3 cooperate tightly until the fastener 4 is pressed on the anti-loosening sheet 5, at this time, under the cooperation relationship between the through end 41 and the sleeve 3, the inner skin 2 and the outer skin 1 maintain a relative position relationship, and the inner skin 2 is prevented from detaching from the outer skin 1; then the folding ear 6 is bent, and each folding ear 6 is buckled on the pressing end 42 to prevent the fastener 4 and the sleeve 3 from loosening, thereby improving stability during use.

[0046] The working principle of this embodiment is: through the provided escape window, the main body of the escape window is formed by the outer skin 1 and the inner skin 2, and the structural stability of the escape window is improved by the first anti-loosening mechanism and the second anti-loosening mechanism to prevent the associated components from loosening or even coming loose during the long-term driving of the vehicle, wherein the first anti-loosening mechanism includes a sleeve 3 fixed on the outer skin 1, and a fastener 4, the fastener 4 has a through end 41 that penetrates the inner skin 2 and cooperates with the sleeve 3 and a pressing end 42 that is pressed on the inner skin 2 to limit the inner skin 2 is separated from the outer skin 1, forming the first angle of anti-loosening purpose, thereby improving the stability of the overall structure; the second anti-loosening mechanism includes an anti-loosening sheet 5 installed between the pressing end 42 and the inner skin 2, and a folding ear 6 arranged on the anti-loosening sheet 5. When the penetration end 41 penetrates the anti-loosening sheet 5 and the inner skin 2 at the same time, and the pressing end 42 is pressed on the anti-loosening sheet 5, the folding ear 6 is bent and pressed on the pressing end 42 to prevent the fastener 4 from escaping from the sleeve 3, thereby forming the second angle of anti-loosening purpose, further improving the stability of the overall structure and improving the safety of the driver and passengers.

[0047] Furthermore, on the basis of the above embodiment, a reinforcing rib 7 is fixedly provided on the outer skin 1, and the reinforcing rib 7 is located in the assembly gap and is supported in the assembly gap by the reinforcing rib 7 to avoid deformation of the inner skin 2 or the outer skin 1 due to excessive fit between the fastener 4 and the sleeve 3, thereby improving the stability of the escape window.

[0048] It is worth noting that the reinforcing rib 7 is "U"-shaped, and one end of the "U"-shaped reinforcing rib 7 with an opening is fixed on the outer skin 1, and the other end of the "U"-shaped reinforcing rib 7 is abutted against the inner side of the inner skin 2, so as to maintain a stable distance between the inner skin 2 and the outer skin 1 through the "U"-shaped reinforcing rib 7.

[0049] Furthermore, on the basis of the above-mentioned embodiment, the outer skin 1 is provided with a hinge 8 for being mounted on the vehicle body, so as to facilitate the opening and closing of the escape window when needed and improve the convenience of operation.

[0050] Furthermore, on the basis of the above embodiment, the escape window also has a locking mechanism, which includes a connecting rod 91, a driving wheel 92 and a fixing seat 93, wherein the fixing seat 93 is arranged in the assembly gap, and the fixing seat 93 is fixedly connected to the center of the inner skin 2, the driving wheel 92 is rotatably arranged on the fixing seat 93, one end of the connecting rod 91 is hinged on the edge of the driving wheel 92, and when the driving wheel 92 rotates, the other end of the connecting rod 91 is driven to extend into the locking hole of the vehicle body, so as to lock the escape window on the vehicle body.

[0051] When the escape window needs to be frequently switched between the open and closed states, the driving wheel 92 is controlled to rotate, and under the rotation of the driving wheel 92, the connecting rod 91 is driven to move, and the end of the connecting rod 91 away from the driving wheel 92 extends into or out of the corresponding lock hole on the vehicle body, and a plurality of connecting rods 91 arranged in different directions can be connected to one driving wheel 92 to improve stability in the locked state.

[0052] Furthermore, on the basis of the above embodiment, the locking mechanism also includes a reinforcement block 94, and the reinforcement block 94 is fixed in the assembly gap, and the reinforcement block 94 is fixedly connected to the inner skin 2, and the reinforcement block 94 is provided with a guide space for accommodating the passage of the connecting rod 91, so that the connecting rod 91 can extend into or move out of the locking hole of the vehicle body under the guidance of the guide space. It should be noted here that when the connecting rod 91 is driven by the driving wheel 92, the connecting rod 91 is not in an axial moving state, and the inner diameter of the guide space close to the driving wheel side is larger than the inner diameter of the other side, so as to provide the necessary space for the movement of the connecting rod 91.

[0053] Furthermore, based on the above embodiment, the locking mechanism further includes an unlocking handle 95 , and the unlocking handle 95 is fixed on the driving wheel 92 to drive the driving wheel 92 to rotate, so as to improve the convenience of operating the driving wheel 92 to rotate.

[0054] On the basis of adding the unlocking handle 95, an operating opening can be opened on the inner skin 2, and the unlocking handle 95 can be extended into the operating opening, so as to further improve the convenience of operation and improve the space utilization without occupying the space inside the vehicle.

[0055] Furthermore, on the basis of the above embodiment, a supporting mechanism is also provided on the inner skin 2, and the supporting mechanism includes a supporting rod 10, one end of the supporting rod 10 is hinged to the inner side of the inner skin 2, and the other end of the supporting rod 10 is operably pressed against the vehicle body for supporting between the inner skin 2 and the vehicle body so as to keep the escape window in a semi-open state.

[0056] When the escape window needs to be in a semi-open state and remain stable, the support rod 10 can be rotated and unfolded in the semi-open state so that the end of the support rod 10 away from the inner skin 2 is abutted against the vehicle body to keep the escape window stably in the semi-open state.

[0057] Furthermore, on the basis of the above embodiment, the support mechanism also includes a support 11, a torsion spring 12 and a rotating rod 13, the support 11 is fixed on the inner skin 2, the rotating rod 13 is rotatably arranged on the support 11 and is fixedly connected to the support rod 10, the torsion spring 12 is sleeved on the rotating rod 13, and is used to drive the support rod 10 to approach the inner skin 2 without being affected by external force.

[0058] The support rod 10 is fixedly connected to the rotating rod 13 and rotates synchronously with the rotating rod 13. The rotating rod 13 is arranged on the support 11 and rotates. At the same time, when the escape window is opened or closed, the support rod 10 does not need to be unfolded and does not play a supporting role. When the escape window is in a semi-open state, the support rod 10 is in an unfolded and supported state. The torsion spring 12 makes it necessary to apply external force to the support rod 10 to maintain it in the unfolded and supported state, and when the external force is cancelled, it can be restored to the non-expanded state, which is easy to operate.

[0059] Furthermore, on the basis of the above embodiment, a protrusion 14 is fixedly provided on the circumferential surface of the rotating rod 13, and a limiting groove 15 for accommodating the movement of the protrusion 14 is provided on the support 11. The limiting groove 15 limits the rotation range of the rotating rod 13 by limiting the movement of the protrusion 14, thereby preventing the support rod 10 from hitting the inner skin 2.

[0060] When the support rod 10 is not subjected to external force and is in an unfolded state, in order to avoid the support rod 10 hitting the inner skin 2 or the outer skin 1 of the escape window, causing noise or collision wear, and because the displacement of the support rod 10 will inevitably drive the rotating rod 13 to rotate synchronously, then during the rotation of the rotating rod 13, the protrusion 14 is constrained by the limiting groove 15, thereby limiting the rotation amplitude of the rotating rod 13, and then limiting the displacement distance of the support rod 10, avoiding collision caused by excessive movement of the support rod 10.

[0061] Based on the same inventive concept, the present application also provides a vehicle, including the above-mentioned escape window, and except for the structure of the above-mentioned escape window, the setting positions and connection methods of other components are conventionally set with reference to the prior art, and will not be elaborated here.
