[0002] With the development of diversified applications of operating machinery, the structure of operating machinery tends to be refined, humanized, and convenient for operation and maintenance. For example, taking excavators as an example, at this stage, excavators generally operate in complex and dangerous environments, and there are situations where the driver needs to escape from the cab in an emergency. For safety reasons, the front windows and top windows of some cabs are equipped with protective structures such as sturdy protective nets, and the side windows of the cab will be blocked by the boom of the working device. When escaping, you can only rely on the door or rear window to escape. However, when the cab collides or overturns, the door is damaged and deformed and cannot be opened, so you can only escape through the rear window.

[0003] In the prior art, the escape window of the excavator, such as the rear window of the cab, is generally a fixed glass window. When escaping, the rear window needs to be opened by violently breaking the glass, which is a destructive opening. Moreover, in daily situations such as normal operation of the excavator, the escape window cannot be opened, which affects the air circulation in the cab and the ventilation effect in the cab is poor.

[0004] Therefore, how to solve the problem of poor ventilation effect of the cab under normal circumstances due to the escape window in the prior art being able to be opened destructively has become an important technical problem to be solved by those skilled in the art. Summary of the invention

[0043] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] Combine the following Figures 1 to 10 The escape window of the present invention is described.

[0045] like Figures 1 to 10 As shown, the escape window provided by the embodiment of the present invention includes a window frame 1, a movable window 2 and a locking mechanism 3.

[0046] Specifically, the window frame 1 is provided with an opening for installing the movable window 2. The movable window 2 is arranged at the opening, and one end of the movable window 2 is rotatably connected to the window frame 1. By rotating the movable window 2, the opening of the window frame 1 can be opened or closed.

[0047] The locking mechanism 3 is disposed between the movable window 2 and the window frame 1 . At at least two rotation positions of the movable window 2 , the locking mechanism 3 can be switched between a locked state and an unlocked state.

[0048] When the locking mechanism 3 is switched to the locking state, the locking mechanism 3 can limit the movable window 2 from rotating relative to the window frame 1 , so that the movable window 2 is fixed at a corresponding rotation position.

[0049] When the locking mechanism 3 is switched to the unlocked state, the movable window 2 can rotate relative to the window frame 1 , so that the movable window 2 can be rotated to another rotation position.

[0050] When the movable window 2 is in one of the at least two rotation positions, the movable window 2 can close the opening, that is, the escape window is in a closed state, referring to Figures 1 to 3 When the movable window 2 is in other rotation positions, the escape window is in the open state. Figures 4 to 6 , used for daily ventilation to improve the ventilation effect of the cab.

[0051] At least one of the movable window 2 and the window frame 1 is detachably connected to the locking mechanism 3. When escaping is required, the movable window 2 and the locking mechanism 3 are detached or the window frame 1 is detached from the locking mechanism 3, and the restriction of the locking mechanism 3 on the rotation position of the movable window 2 can be cancelled. At this time, the escape window is in an emergency escape state. Figure 7 and Figure 8, the escape window can be opened at a larger angle, and the escapee can rotate the escape window as needed when escaping. After the escape is completed, the movable window 2 can be connected to the locking mechanism 3 or the window frame 1 can be connected to the locking mechanism 3 in the later stage and continue to be put into use.

[0052] With such a configuration, the escape window provided by the embodiment of the present invention can not only meet the need for escape, but also can fix the movable window 2 in a certain position through the locking mechanism 3 under normal circumstances, so that the escape window remains open for daily ventilation, thereby enhancing the ventilation effect of the cab, and solving the problem of poor ventilation effect of the cab under normal circumstances caused by the escape window in the prior art being able to be opened destructively.

[0053] It should be noted that the escape window provided in the embodiment of the present invention can be applied to the rear window of the cab, and can also be applied to the front window or side window of the cab.

[0054] In this embodiment, the movable window 2 can be fixed in at least three rotation positions by the locking mechanism 3. When the movable window 2 is in one of the rotation positions, the escape window is in a closed state. When the movable window 2 is in at least the other two rotation positions, the escape window is in an open state. When the movable window 2 is in different rotation positions, the escape window has different openings, thereby realizing multi-level adjustment of the opening of the escape window. Under normal circumstances, the position of the movable window 2 can be adjusted as needed.

[0055] To ensure the stability of the movable window 2, two locking mechanisms 3 may be provided, and the two locking mechanisms 3 are distributed at both ends of the movable window 2 along the rotation axis of the movable window 2 relative to the window frame 1, so that the movable window 2 is subjected to balanced forces.

[0056] In the embodiment of the present invention, the locking mechanism 3 is configured to be connected with the window frame 1 and the movable window 2 to form a planar linkage mechanism, so that when the planar linkage mechanism is in a dead point position, the escape window is just in a closed state. The dead point position is used to keep the escape window in a closed state, which can improve the stability of the escape window.

[0057] Specifically, the locking mechanism 3 includes a first connecting member 4 and a second connecting member 5 .

[0058] The first end of the first connecting member 4 is rotatably connected to the movable window 2, the first end of the second connecting member 5 is rotatably connected to the second end of the first connecting member 4, and the second end of the second connecting member 5 is rotatably connected to the window frame 1. The above-mentioned rotational connection positions can all be achieved by pin hinges.

[0059] The rotation axis of the first connecting member 4 relative to the movable window 2 , the rotation axis of the second connecting member 5 relative to the first connecting member 4 and the rotation axis of the second connecting member 5 relative to the window frame 1 are all parallel to the rotation axis of the movable window 2 relative to the window frame 1 .

[0060] For the convenience of explanation, it is now stipulated that the rotation axis of the first connecting member 4 relative to the second connecting member 5 is a reference axis, and the pin axis used to hinge the first connecting member 4 and the second connecting member 5 together is a reference axis.

[0061] A limiting groove 6 is provided on one of the first connecting member 4 and the second connecting member 5. At least two limiting grooves 6 are provided. Each limiting groove 6 is distributed around the reference axis, that is, each limiting groove 6 is distributed along the circumference of the reference axis. Fig.10 .

[0062] A clamping assembly is provided on the other of the first connecting member 4 and the second connecting member 5 , and the clamping assembly can be clamped with any one of the limiting grooves 6 .

[0063] When the clamping assembly is clamped with one of the limiting grooves 6 , the first connecting member 4 and the second connecting member 5 can be restricted from rotating relative to each other through the interaction between the clamping assembly and the limiting groove 6 , thereby restricting the movable window 2 from rotating relative to the window frame 1 .

[0064] When the snap-fit ​​assembly is snap-fitted with different limiting grooves 6 , the first connecting member 4 and the second connecting member 5 have different relative positions, so that the movable window 2 and the window frame 1 have different relative positions, and the escape window has different openings.

[0065] The above-mentioned limit groove 6 can be set on the first connecting member 4 or on the second connecting member 5. The structure of the locking mechanism 3 is described below by taking the limit groove 6 set on the first end of the second connecting member 5 as an example. In this case, the clamping assembly is set on the second end of the first connecting member 4, and a gear structure can be set on the first end of the second connecting member 5. The gear structure is relatively fixed to the second connecting member 5, and the space between any two adjacent gear teeth of the gear structure constitutes the above-mentioned limit groove 6.

[0066] In a further embodiment, the clamping assembly includes an elastic member 13 and a clamping block 7, and the clamping block 7 can extend into the limiting groove 6. The clamping block 7 is disposed at the second end of the first connecting member 4, and the clamping block 7 is slidably connected to the first connecting member 4. When the clamping block 7 slides relative to the first connecting member 4, it can approach or move away from the limiting groove 6.

[0067] When the block 7 slides into the limiting groove 6 in the direction close to the limiting groove 6, the interaction between the block 7 and the limiting groove 6 can limit the relative rotation of the first connecting member 4 and the second connecting member 5. At this time, the locking mechanism 3 is in a locked state.

[0068] When the clamping block 7 slides in a direction away from the limiting groove 6 until it is disengaged from the limiting groove 6 , the first connecting member 4 and the second connecting member 5 can rotate relative to each other. At this time, the locking mechanism 3 is in an unlocked state.

[0069] The elastic member 13 is disposed between the block 7 and the first connecting member 4, and the elastic member 13 makes the block 7 have a tendency to approach the limiting groove 6. Fig.10 .

[0070] When the movable window 2 and the first connecting member 4 and the second connecting member 5 are not subjected to external forces, the clamping block 7 can maintain clamping connection with the limiting groove 6 under the action of the elastic member 13 to ensure the stable position of the movable window 2.

[0071] When the rotation position of the movable window 2 needs to be changed, for example, when the escape window needs to be opened, closed, or the opening of the escape window needs to be adjusted, a force that enables the first and second connecting members 4 and 5 to rotate relative to each other is applied to the movable window 2, the first connecting member 4, or the second connecting member 5, so that the clamping block 7 overcomes the force of the elastic member 13 under the action of the limiting groove 6 and gradually moves away from the limiting groove 6 until the clamping block 7 is disengaged from the limiting groove 6, at which time, the first connecting member 4 and the second connecting member 5 can rotate relative to each other. When the first and second connecting members 4 and 5 rotate relative to each other until the clamping block 7 is opposite to another limiting groove 6, the clamping block 7 approaches the limiting groove 6 under the action of the elastic member 13 and slides to be engaged with the limiting groove 6.

[0072] In this embodiment, the locking mechanism 3 can automatically switch between the locked state and the unlocked state according to the force, and the escapee only needs to rotate the escape window, which is easy to operate.

[0073] The elastic member 13 may be, but is not limited to, a compression spring, which is located on a side of the block 7 away from the limiting groove 6 , with one end of the compression spring resting on the block 7 and the other end resting on the first connecting member 4 .

[0074] In this embodiment, in order to facilitate the escapee to apply force to the locking mechanism 3, a holding portion 11 is provided on one of the first connecting member 4 and the second connecting member 5. When the escapee switches the state of the locking mechanism 3, the escapee applies force to the holding portion 11, which can improve the operating comfort.

[0075] In this embodiment, one of the first connecting member 4 and the second connecting member 5 is provided with a receiving groove 14 for accommodating the other, which can reduce the size of the locking mechanism 3 along the reference axis direction and increase the angular range of relative rotation between the first connecting member 4 and the second connecting member 5.

[0076] In the embodiment of the present invention, a mounting seat is provided on the movable window 2, a first hinge hole is provided on the mounting seat, a second hinge hole is provided on the locking mechanism 3, and the locking mechanism 3 is hinged to the mounting seat by a connecting pin 8. For example, a second hinge hole is provided at the first end of the first connecting member 4, and the first connecting member 4 is hinged to the mounting seat by a connecting pin 8, so that a detachable connection between the locking mechanism 3 and the movable window 2 can be achieved.

[0077] During emergency escape, the movable window 2 can be separated from the locking mechanism 3 by removing the connecting pin 8. When installing the escape window, ensure that the locking mechanism 3 is located in the cab.

[0078] A pull ring is provided at the end of the connecting pin 8, which is convenient for applying force when disassembling the connecting pin 8. In order to prevent the connecting pin 8 from accidentally falling off, a locking pin can be provided at the other end of the connecting pin 8, and the pull ring and the locking pin can prevent the axis of the connecting pin 8 from moving, thereby preventing it from falling off.

[0079] In a specific embodiment, the mounting seat includes a stopper 9 and a third connecting member 10. The stopper 9 has a stopper portion and a connecting member. A through hole for the connecting member to penetrate is provided on the movable window 2. The stopper portion and the third connecting member 10 are respectively located on both sides of the movable window 2. The connecting member can penetrate the movable window 2 through the through hole, and the third connecting member 10 is connected to the connecting member. The stopper portion and the third connecting member 10 both abut against the movable window 2. Through the interaction between the stopper portion and the movable window 2 and the interaction between the third connecting member 10 and the movable window 2, the connection between the mounting seat and the movable window 2 can be ensured to be stable.

[0080] Specifically, an external thread may be provided on the connection portion, and a threaded hole may be provided on the third connection member 10 , so that the connection portion and the third connection member 10 are threadedly connected.

[0081] In the embodiment of the present invention, the escape window includes a glass plate and a sealing strip, and the shape and size of the glass plate are adapted to the shape and size of the opening on the window frame 1. One end of the glass plate is rotatably connected to the window frame 1, and the other end is connected to the locking mechanism 3.

[0082] The glass plate and the window frame 1 can be connected by hinge components such as hinges.

[0083] The sealing strip wraps around the edge of the glass plate along the circumference of the glass plate. When the escape window is in a closed state, the glass plate is pressed against the window frame 1 by the sealing strip, which can ensure the sealing of the escape window to prevent external rain, dust, etc. from entering the cab.

[0084] In this embodiment, the escape window further includes a wiper 12, which is disposed on the glass plate. The wiper 12 can be used to clean the glass plate to ensure a clear field of vision of the escape window.

[0085] The escape window in the embodiment of the present invention can satisfy the window vision and ventilation functions in the field of engineering machinery, and can be used as an escape passage without damaging the window. Moreover, by plugging and pulling the connecting pin 8 in the cab, the escape window can be easily opened and closed to meet various scene requirements such as ventilation and personnel escape. The entire escape window has a simple structure, is easy to operate, and has low cost, and has a high reference value in the engineering machinery industry.

[0086] On the other hand, an embodiment of the present invention further provides a cab, comprising an escape window provided in any of the above embodiments. The escape window provided in the above embodiments can be used for both emergency escape and daily ventilation. Therefore, the cab in this embodiment has the advantages of high safety and good ventilation. The derivation process of the beneficial effects of the cab in the embodiment of the present invention is generally similar to the derivation process of the beneficial effects of the above escape window, so it will not be repeated here.

[0087] The escape window provided in the above embodiment can be applied to the rear window position of the cab, and can also be applied to the front window position of the cab, which is not limited here. When installing the escape window, ensure that the locking mechanism 3 is located in the cab.

[0088] In some embodiments, the escape window provided in the above embodiments is applied to the rear window of the cab. The rear window of the cab does not need to be provided with a protective net, which can avoid the problem of difficulty in opening caused by deformation of the protective net.

[0089] The movable window 2 may be arranged in a horizontal direction relative to the rotation axis of the window frame 1 , or may be arranged in a vertical direction relative to the rotation axis of the window frame 1 , which is not limited here.
