[0032] Example 1
[0033] In a typical embodiment of the present invention, Figure 1-Figure 7 As shown, a cab sliding window structure is provided.
[0034] The traditional cab 6 windows have the problem of being unable to be effectively ventilated on rainy days and easily blocking the field of vision. Based on this, the present embodiment provides a cab sliding window structure, using the window 2 in combination with other components to form a rocker slider 3 mechanism. The window 2 acts as a connecting rod and can follow the movement of the bracket 5 as a rocker, and drive the slider 3 to move along the slide rail 4, so that the window 2 can switch between closed and open states. When the window 2 is in the open state, it can be close to the top surface of the cab 6, and one end can be extended out of the cab 6 as a rainproof edge, thereby increasing the openness of the cab 6 and reducing the obstruction of the field of vision to meet the needs of rainy days.
[0035] See also Figure 1 The cab sliding window structure includes a window body 2, a bracket 5 and a window frame 1, wherein the window frame 1 is installed in the cab 6, and the window frame 1 can cooperate with the window body 2. When the window body 2 cooperates with the window frame 1, the entire window frame 1 can be blocked, and when opened, the window frame 1 can be opened for ventilation. In order to realize the connection between the window 2 and the window frame 1, a slider 3 is rotatably connected to the side of the window 2, and the slider 3 is slidably matched with a slide rail 4 arranged on the side of the window frame 1. When the window 2 drives the slider 3 to slide along the window frame 1, the window 2 changes the angle with the window frame 1.
[0036] One end of the bracket 5 is suspended and hinged in the cab 6, and the other end is rotatably connected to the side of the window 2. When the window 2 is opened or closed relative to the window frame 1, it also rotates relative to the bracket 5. The position where the bracket 5 is connected to the window 2 is spaced apart from the slider 3 on the window 2. The bracket 5, the window 2 and the cab 6 together form a rocker slider 3 mechanism.
[0037] like Figure 2 As shown, in the rocker slider 3 mechanism, the cab 6 carrying the bracket 5 and the window frame 1 slide rail 4 serves as a frame, the bracket 5 serves as a rocker, the window 2 serves as a connecting rod, and the slider 3 cooperates with the slide rail 4 to form a sliding structure. The rotation of the rocker relative to the cab 6 can be transmitted to the slider 3 through the window 2, and while rotating the window 2, the slider 3 is also driven to slide along the slide rail 4.
[0038] In this embodiment, Figure 1 As shown, the window 2 cooperates with the window frame 1 of the cab 6, and the slider 3 is rotatably connected to the side, so that the window 2 can slide and flip along the slide rail 4. The slider 3 is arranged on the side of the window 2, and slides with the slide rail 4 on the side of the window frame 1 to achieve stable movement and flipping of the window 2.
[0039] The window 2 can not only be turned over in a position to match the blocking window frame 1, but also be located on the top of the cab 6 after turning over, with one end sticking out of the cab 6 to form a rainproof edge. The window 2 can be opened for ventilation on rainy days, while preventing rainwater from directly entering the cab 6.
[0040] The windows of the traditional cab 6 are closed on rainy days for fear of rainwater infiltration, resulting in poor ventilation in the cab 6, affecting the driver's comfort and work efficiency. In this embodiment, the window 2 is flipped and extended out of the cab 6 to form a rainproof edge, which effectively solves the ventilation problem on rainy days. The fully open window 2 design reduces the obstruction of the field of vision, improves the driver's field of vision, and enhances driving safety.
[0041] The design of the rocker slider 3 mechanism makes the flipping and sliding operation of the window 2 simple and fast, improving the user experience, improving the driving environment, making it possible to effectively ventilate the cab 6 even on rainy days, keeping the air in the cab 6 fresh, and improving the comfort of the driver.
[0042] The sides of the window 2 are rotatably connected with sliders 3, and two independent rocker slider 3 mechanisms are formed on both sides of the window 2 through the sliders 3. The window 2 is a rigid structure. Therefore, when the window 2 is flipped open or closed relative to the window frame 1, the rocker slider 3 mechanisms on both sides of the window 2 can move synchronously to maintain the stability and balance of the window 2, and prevent deformation or jamming caused by uneven force on one side.
[0043] like Figure 1 and Figure 3 As shown, a crossbeam is connected between the brackets 5 on both sides of the window 2, and a gas strut 10 is connected between the bracket 5 and the cab 6. By installing the crossbeam, the overall rigidity and stability of the window 2 structure can be increased. At the same time, the gas strut 10 is installed between the bracket 5 and the cab 6 to provide additional support for the window 2 and assist the smooth transition of the window 2 during the flipping process.
[0044] A handle 7 is provided on the side of the window 2 facing the cab 6 for easy operation by the driver. A lock body 8 is provided on the handle 7, and a lock hole 9 capable of being locked with the lock body 8 is provided on the bracket 5. The locking function of the window 2 is realized through the cooperation of the lock body 8 and the lock hole 9, providing a convenient locking mechanism to ensure the safety and stability of the window 2 in the closed state. This prevents the window 2 from being accidentally opened during driving, causing safety hazards.
[0045] The lock body 8 is located between the side of the window 2 where the bracket 5 is connected and the side of the window 2 where the slider 3 is connected, and the lock tongue of the lock body 8 extends to the outside of the side of the window 2 to match the lock hole 9. The lock body 8 can effectively lock the window 2 without affecting the flipping and sliding of the window 2. The position of the lock body 8 is reasonable, which does not affect the normal operation of the window 2 and can ensure the reliability of locking.
[0046] The slide rails 4 are arranged along the two sides of the window frame 1 to ensure that the window 2 can maintain a stable fit with the slide rails 4 during the entire flipping and sliding process. The stability and smoothness of the window 2 during the flipping and sliding process are guaranteed, and the problem of the window 2 being stuck or damaged due to insufficient length of the slide rails 4 is reduced.
[0047] like Figure 1 As shown, when the window 2 is in a closed state, the circumferential edge of the window 2 fits with the circumferential edge of the window frame 1. In order to ensure the sealing of the window 2 after closing, in this embodiment, sealing strips are respectively provided at the fitting positions of the circumferential edge of the window 2 and the circumferential edge of the window frame 1, and the sealing strips are used to seal the relative fitting positions to reduce the problem of rainwater leakage when the window 2 is closed.
[0048] like Figure 3 As shown, after the window 2 is opened, the window 2 is in a nearly horizontal state as a whole. In order to achieve the function of rainproof edge, the end of the window 2 located inside the cab 6 is higher than the end located outside the cab 6, and the whole is inclined relative to the horizontal plane. The window 2 located outside the cab 6 partially blocks rainwater while allowing rainwater to flow along the top surface of the window 2 toward the end away from the cab 6, thereby preventing rainwater from flowing back into the cab 6.
[0049] The bracket 5 structure is installed in the cab 6 in a suspended manner. After the window 2 is opened, the lock body 8 on the window 2 can be used to cooperate with the lock hole 9 on the bracket 5 to form a lock, thereby fixing the position of the window 2 and keeping the position of the window 2 stable. The end of the window 2 located outside the cab 6 is lower than the end located inside the cab 6, so that the window 2 can be in a tilted state. When used as a rainproof edge, it can prevent rainwater from flowing back into the cab 6, thereby improving the rainproof effect.
[0050] For form 2 from Figure 1 The closed state in Figure 3 The opening state process in is described as follows:
[0051] The window 2 is in a closed state as an initial state, and the driver can hold the handle 7 to apply a driving force to the window 2; because the handle 7 is located between the slider 3 and the bracket 5 where the window 2 is connected, by pulling the handle 7, the window 2 segment below the slider 3 can be flipped outward, and the window 2 segment above the slider 3 can be flipped inward;
[0052] As the window 2 flips, the slider 3 is pulled by the window 2 and slides up along the track; as the window 2 flips further, the upper end of the window 2 moves toward the inside of the cab 6 until the bracket 5 is perpendicular to the window 2;
[0053] The entire window 2 is pushed up by the handle 7 so that the window 2 is close to the top surface of the cab 6, and the slider 3 continues to slide up along the slide rail 4, and the handle 7 gradually approaches the bracket 5 until the lock body 8 of the handle 7 cooperates with the lock hole 9 on the bracket 5 to form a lock, so that the relative rotation of the bracket 5 and the window 2 is locked, the window 2 is opened, and the space below the window 2 is opened, thereby reducing the obstruction of the field of vision.
[0054] For form 2 from Figure 3 The open state in Figure 1 In the closed state, the process is opposite to the above-mentioned opening process. The lock body 8 is first unlocked. After unlocking, the window body 2 is reset to block the window frame 1 by pulling down and pushing the handle 7 forward.
[0055] It is understandable that a lock structure may also be provided on the side of the window frame 1 , so that when the window 2 is in a closed state, the lock body 8 cooperates with the lock on the side of the window frame 1 to fix the position of the window 2 and the window frame 1 .
[0056] Example 2
[0057] In another typical embodiment of the present invention, Figure 1-Figure 7 As shown, an engineering machinery with a cab sliding window structure is provided, utilizing the cab sliding window structure as in Example 1.
[0058] The cab sliding window structure is installed on the rear side of the engineering machinery cab 6 . When the window 2 is opened relative to the window frame 1 , the window 2 can be adjusted to face the top surface of the cab 6 .
[0059] Specifically, the cab sliding window structure is mainly composed of a window body 2, a slide rail 4, a slider 3, a bracket 5, a crossbeam, a gas strut 10, a handle 7 and a lock body 8. The components work together to realize the flipping, sliding and locking functions of the window body 2. Among them, the window body 2 is the main part of the sliding window structure, which cooperates with the window frame 1 of the cab 6. The window body 2 is usually made of transparent materials (such as glass or reinforced plastic) to ensure good vision and light transmittance. The window 2 is also set to a material of a transparent plate combined with a frame. The side edges of the window body 2 are rotatably connected with sliders 3, and the sliders 3 slide with the slide rails 4 arranged on the side of the window frame 1 to realize the flipping and sliding functions of the window 2.
[0060] The slide rails 4 are arranged along the two sides of the window frame 1 to ensure that the window 2 can maintain a stable fit with the slide rails 4 during the entire flipping and sliding process. The sliders 3 are installed on the two sides of the window 2 and form a sliding connection with the slide rails 4, so that the window 2 can flip and slide smoothly along the slide rails 4.
[0061] One end of the bracket 5 is suspended and hinged in the cab 6, and the other end is rotatably connected to the side of the window 2 and arranged at intervals with the slider 3. The bracket 5 serves as the crank part of the rocker slider 3 mechanism, and together with the window 2 (as a connecting rod) constitutes the rocker slider 3 mechanism. A crossbeam is connected between the brackets 5 on both sides of the window 2 to increase the overall rigidity and stability of the window 2 structure. The design of the crossbeam helps prevent the window 2 from shaking when it is turned over or in windy weather.
[0062] When the window 2 needs to be opened for ventilation or observation, the driver can operate the handle 7 to flip and slide the window 2 along the slide rail 4. During the flipping process, the gas strut 10 provides auxiliary support force to ensure a smooth transition of the window 2. When the window 2 is flipped to the desired position, the window 2 is locked in a fixed position through the cooperation of the lock body 8 and the lock hole 9. In this way, the purpose of ventilation and observation can be achieved, and the safety and stability of the cab 6 can be ensured.
[0063] When the above cab sliding window structure is applied to engineering machinery, the ventilation effect and visual range of the cab 6 can be significantly improved. At the same time, the structural form also has the advantages of convenient operation, good stability, high safety, etc., and can meet the use requirements of engineering machinery under different working conditions.
[0064] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
