[0065] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present disclosure and its application or use. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure.

[0066] Unless otherwise specifically stated, the relative arrangement of the parts and steps, numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present disclosure. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to actual proportional relationships.

In all examples shown and discussed here, any specific values should be interpreted as being merely exemplary, rather than as limitations. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0067] In the description of the present disclosure, it should be understood that the use of words such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above words have no special meaning and therefore cannot be understood as limiting the scope of protection of the present disclosure.

[0068] In the description of the present disclosure, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present disclosure and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present disclosure; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0069] In the process of realizing the present disclosure, the inventors discovered that when the driver of a construction machinery is performing operations, in situations where the viewing angle needs to be frequently adjusted, such as when performing excavation and loading operations under harsh working conditions, since the bars of the protective grille have a certain width, regardless of whether the bars are arranged horizontally or vertically, when the driver observes the external environment of the cab at an angle, the driver's field of vision will be obstructed by the bars. The protective grilles used in related technologies are difficult to adapt to the driver's requirements for the field of vision.

[0070] To improve the above problems, refer to Figures 1 to 17 Some embodiments of the present disclosure provide a cab assembly including a cab 6 and a protective grille. The cab 6 has at least one window. The protective grille is configured to provide protection for the cab 6 and includes at least one adjustable grille. The at least one adjustable grille corresponds to the position of at least one window and is adjustable relative to the corresponding window to change the angle of bars B of the adjustable grille relative to the corresponding window.

[0071] Optionally, refer to Figure 1 and Figure 2 The protective grille has a cage-like structure as a whole, and the protective grille cover is arranged on the cab 6 to form a closed protective frame surrounding the cab 6.

[0072] Optionally, refer to Figure 1 and Figure 2 The protective grille includes at least one front grille 1 , at least one rear grille 2 , at least one left grille 3 , at least one right grille 4 and at least one top grille 5 .

[0073] Optionally, the protective grille includes at least one adjustable grille and at least one fixed grille. The cab assembly includes a support portion, and each fixed grille is fixedly mounted to the cab 6 via at least one support portion. To enhance the overall strength of the protective grille, the support portion can be made of high-strength material. Threaded connectors can be used to connect the support portion to the cab 6 and to the protective grille, ensuring both connection strength and ease of assembly and disassembly. Optionally, a mounting bracket is welded to the cab 6, and the support portion is connected to the mounting bracket via a threaded connector.

[0074] In some embodiments of the cab assembly, reference Figure 3 、 Figure 5 and Figure 6 The at least one adjustable grille includes a first front grille 11 . The at least one vehicle window includes a front window 61 . The first front grille 11 is disposed in front of the cab 6 and is adjustable relative to the front window 61 .

[0075] In some embodiments of the cab assembly, reference Figures 4 to 6 The at least one adjustable grille includes a first rear grille 21. The at least one vehicle window includes a rear window 62. The first rear grille 21 is disposed behind the cab 6 and is adjustable relative to the rear window 62.

[0076] In some embodiments of the cab assembly, reference Figures 3 to 6 , at least one adjustable grille includes the aforementioned first front grille 11 and the aforementioned first rear grille 21.

[0077] According to the actual usage scenarios and usage requirements of the construction machinery, in some embodiments not shown in the figures, the protective grille may also include more or fewer adjustable grilles, and the adjustable grilles are not limited to being set in front and behind the cab 6. For example, they can also be set on both sides of the cab 6 along its own width direction.

[0078] In the cab assembly provided by the embodiments of the present disclosure, the protective grille includes at least one adjustable grille, whose angle relative to the vehicle window is adjustable. The adjustable grille's position relative to the corresponding vehicle window can be dynamically adjusted based on changes in the driver's line of sight under different operating conditions, and the angle of the bars B relative to the corresponding vehicle window can be changed accordingly, thereby improving the degree of field of vision. In operating conditions requiring frequent adjustments to the viewing angle, the dynamic adjustment of the adjustable grille's position relative to the corresponding vehicle window allows the driver's line of sight to be aligned with the gaps between the bars B, reducing the obstruction of the bars B to the driver's field of view and narrowing blind spots.

[0079] It can be seen that the cab assembly provided by the embodiment of the present disclosure can not only protect the cab 6 from possible impacts through the protective grille, but also reduce the adverse effects of the protective grille as a cab protection structure on the driver's field of vision by arranging an adjustable grille in the protective grille, thereby reducing safety hazards of construction machinery when driving or operating.

[0080] In the cab assembly of some embodiments, the adjustable grille is rotatably provided around an axis along the width direction of the cab 6 .

[0081] Considering the obstruction of the driver's field of vision by the horizontal bars B in the protective grille, refer to Figures 5 to 8 In this embodiment, when the driver looks obliquely upward or downward, by rotating the adjustable grille around the axis along the width direction of the cab 6 at a certain angle, the driver's line of sight can be directed to the gap between the bars B, thereby reducing the blind spot of vision.

[0082] In the cab assembly of some embodiments, the rotation axis of the adjustable grille is arranged at one end thereof close to the bottom of the cab 6 .

[0083] In this embodiment, considering that many types of engineering machinery have a working device located in the lower front side of the cab 6, during operation, the cab needs to always observe the location of the working device and the surrounding environment. Based on the setting method of the rotation axis of the adjustable grille in this embodiment, not only can the blind spot of vision be reduced by adjusting the posture of the adjustable grille, but also when the adjustable grille rotates, the end of the adjustable grille close to the bottom of the cab 6, that is, the end close to the working device, has a smaller rotation amplitude, while the end close to the top of the cab 6, that is, the end away from the working device, has a larger rotation amplitude, which can reduce the risk of interference between the adjustable grille and the working device when adjusting the angle.

[0084] In some embodiments of the cab assembly, reference Figures 5 to 8 The adjustable grille can rotate between a first position and a second position. In the first position, the adjustable grille is arranged along the height direction of the cab 6. From the first position to the second position, the end of the adjustable grille close to the top of the cab 6 gradually moves away from the cab 6.

[0085] In this embodiment, when the construction machine is in motion, the adjustable grille is maintained in the first position so that the gaps between the bars B of the adjustable grille face the direction of motion, thereby reducing the bars B from obstructing the driver's field of vision. When the construction machine is in operation, the adjustable grille can be deflected back and forth between the first and second positions according to actual needs, adjusting the adjustable grille to a position that minimizes the driver's blind spot. Thus, the cab assembly of this embodiment can provide the driver with a good field of vision in both the driving and operating conditions of the construction machine.

[0086] In some embodiments of the cab assembly, reference Figures 5 to 8 The adjustable grille can rotate by 10° between the first position and the second position.

[0087] In this embodiment, the adjustable grille has a 10° rotation range between the first and second positions. That is, in the second position, the adjustable grille forms a 10° angle with the height of the cab 6. This rotation range of the adjustable grille in this embodiment not only reduces the driver's blind spot, but also prevents excessive rotation of the adjustable grille, which would reduce the overall rigidity and strength of the protective grille and create a large gap between the adjustable grille and protective grilles in other positions. This ensures that the protective grille has sufficient protection, thus balancing vision requirements and protection needs.

[0088] Of course, the angle value of the adjustable grille rotating between the first position and the second position can also be set to other values, such as 15°, 20°, etc., according to the actual use scenario and use requirements of the engineering vehicle.

[0089] In some embodiments of the cab assembly, at least one group of telescopic drive parts is provided corresponding to at least one adjustable grille, and each group of telescopic drive parts includes at least one telescopic drive part. The first end of each telescopic drive part in the length direction is hinged to the cab 6, and the second end is hinged to the corresponding adjustable grille. The telescopic drive part drives the end of the adjustable grille close to the top of the cab 6 to move closer to or away from the cab 6 by telescoping along its own length direction.

[0090] The specific form of the telescopic driving part may be, for example, an electric push rod, a hydraulic cylinder or other driving components that can achieve similar telescopic functions.

[0091] Optionally, refer to Figure 5 、 Figure 6 and Figure 9 The at least one group of telescopic driving parts includes a group of front telescopic driving parts 15 corresponding to the first front grille 11 and a group of rear telescopic driving parts 25 corresponding to the first rear grille 21 .

[0092] Optionally, refer to Figure 5 、 Figure 6 and Figure 9 In order to improve the smoothness of the rotation of the adjustable grille, each group of front telescopic drive units 15 includes two front telescopic drive units 15 arranged side by side along the width direction of the cab 6, and each group of rear telescopic drive units 25 includes two rear telescopic drive units 25 arranged side by side along the width direction of the cab 6.

[0093] Optionally, refer to Figure 5 and Figure 6The cab assembly includes at least one rod-shaped front connecting portion 16, one end of each front connecting portion 16 is fixedly connected to the front surface of the cab 6, and the other end is hinged to one end of the adjustable grille near the bottom of the cab 6; the cab assembly includes at least one rear connecting portion 26, one end of each rear connecting portion 26 is fixedly connected to the front surface of the cab 6, and the other end is hinged to one end of the adjustable grille near the bottom of the cab 6.

[0094] Optionally, refer to Figure 9 The cab 6 is topped with a front mounting seat 64, and the first front grille 11 is provided with a front grille mounting seat 17. The front telescopic drive unit 15 is hingedly connected to the front mounting seat 64 and the front grille mounting seat 17 at both ends along its length via pins. The connection structure and relationship between the rear telescopic drive unit 25, the cab 6, and the first rear grille 21 are similar to those of the front telescopic drive unit 15 and will not be further described here.

[0095] In some embodiments of the cab assembly, at least one control knob is provided corresponding to at least one group of telescopic drive parts, and each control knob is operably connected to the corresponding telescopic drive part. In response to the rotation of the control knob, the corresponding telescopic drive part performs a telescopic action along its own length direction.

[0096] Optionally, refer to Figure 11 The cab assembly includes a first control knob 71 corresponding to a group of front telescopic drive units 15 and a second control knob 72 corresponding to a group of rear telescopic drive units 25. In response to the rotation of the first control knob 71, the front telescopic drive unit 15 is telescoped along its own length direction; in response to the rotation of the second control knob 72, the rear telescopic drive unit 25 is telescoped along its own length direction.

[0097] Optionally, refer to Figure 11 The cab assembly includes a seat disposed within cab 6, with a first control knob 71 and a second control knob 72 disposed on the seat armrests. The first and second control knobs 71 and 72 correspond to the positions of the construction machinery's operating handles, allowing for switching between operating the working device and adjusting the angle of the protective grille.

[0098] When the construction machine switches from a driving state to an operating state and the driver needs to dynamically adjust the field of view, optionally, by rotating the first control knob 71 clockwise, the front telescopic drive unit 15 extends to drive the end of the first front grille 11 close to the top of the cab 6 away from the cab 6, thereby adjusting the angle of the first front grille 11 relative to the front window 61 to an angle that can reduce obstruction to the driver's field of view, and by rotating the second control knob 72 counterclockwise, the front telescopic drive unit 15 shortens to drive the end of the first front grille 11 close to the top of the cab 6 close to the front window 61. cab 6, thereby resetting the first front grille 11; by rotating the second control knob 72 clockwise, the rear telescopic drive portion 25 extends to drive the end of the first rear grille 21 close to the top of the cab 6 away from the cab 6, thereby adjusting the angle of the first rear grille 21 relative to the rear window 62 to an angle that can reduce obstruction to the driver's field of vision; by rotating the second control knob 72 counterclockwise, the rear telescopic drive portion 25 shortens to drive the end of the first rear grille 21 close to the top of the cab 6 close to the cab 6, thereby resetting the first front grille 11.

[0099] If the telescopic drive part is an electric push rod, the control knob can be connected to the corresponding telescopic drive part signal. If the telescopic drive part is a hydraulic cylinder, the control knob can be connected to the electromagnetic control valve signal of the hydraulic cylinder.

[0100] In some embodiments of the cab assembly, reference Figure 3 The protective grille includes a second front grille 12 and a third front grille 13. The second front grille 12 and the third front grille 13 are respectively arranged on both sides of the first front grille 11 along the width direction of the cab 6. The second front grille 12 and the third front grille 13 are fixedly connected to the cab 6, and the first front grille 11 is rotatably connected to the second front grille 12 and the third front grille 13.

[0101] Optionally, refer to Figure 3 The cab assembly includes at least one front support portion 14, and the aforementioned support portion includes at least one front support portion 14. The second front grille 12 and the third front grille 13 are fixedly connected to the cab 6 through at least one front support portion 14 respectively.

[0102] Optionally, refer to Figure 10 The cab assembly includes a connecting shaft 18, through which one end of the first front grille 11 near the bottom of the cab 6 is rotatably connected to the third front grille 13. There may be multiple connecting shafts 18. In some embodiments (not shown), one end of the first front grille 11 near the bottom of the cab 6 is rotatably connected to the second front grille 12 via another connecting shaft 18.

[0103] In this embodiment, the protective grille in front of the cab 6 includes a first front grille 11, a second front grille 12 and a third front grille 13 which are separately arranged, wherein the first front grille 11 is an adjustable grille which can be adjusted relative to the posture of the cab 6, the second front grille 12 and the third front grille 13 are fixed grilles fixedly connected to the cab 6, and the first front grille 11 is rotatably connected between the second front grille 12 and the third front grille 13. Compared with setting all the protective grilles in front of the cab 6 as adjustable grilles, this setting can make the protective grille in front of the cab 6 have sufficient strength while achieving the function of reducing blind spots.

[0104] In some embodiments of the cab assembly, reference Figure 4 The protective grille includes a second rear grille 22 and a third rear grille 23. The second rear grille 22 and the third rear grille 23 are respectively arranged on both sides of the first rear grille 21 along the width direction of the cab 6. The second rear grille 22 and the third rear grille 23 are fixedly connected to the cab 6, and the first rear grille 21 is rotatably connected to the second rear grille 22 and the third rear grille 23.

The second rear grille 22 and the third rear grille 23 are fixedly connected to the cab 6 through at least one rear support portion 24 respectively.

[0106] In this embodiment, the positional relationship and connection relationship of the first rear grille 21, the second rear grille 22 and the third rear grille 23 can play a similar role as the positional relationship and connection relationship of the first front grille 11, the second front grille 12 and the third front grille 13 in the aforementioned embodiment, and will not be repeated here.

[0107] Optionally, refer to Figure 3 and Figure 4 The second front grille 12 and the third front grille 13 are both L-shaped, and each front support portion 14 extends along the width direction of the cab 6 or extends at an angle to the front-rear direction of the cab 6. The second rear grille 22 and the third rear grille 23 are both L-shaped, and each rear support portion 24 extends along the width direction of the cab 6 or extends at an angle to the front-rear direction of the cab 6.

[0108] In some embodiments of the cab assembly, reference Figure 3 and Figure 4 The protective grille includes the aforementioned second front grille 12 , the third front grille 13 , the second rear grille 22 and the third rear grille 23 .

[0109] In some embodiments of the cab assembly, reference Figures 12 to 14The cab 6 has a door 63 that can swing between a third position and a fourth position to open and close. The protective grille includes a first side grille 31 and a second side grille 32, which are disposed on the sides of the cab 6. In the third position, the door 63 is closed. The first side grille 31 corresponds to the position of the door 63 and is positioned adjacent to the second side grille 32 along the front-to-back direction of the cab 6, thereby providing protection to the sides of the cab 6 together with the second side grille 32. From the third position to the fourth position, the door 63 gradually opens.
