[0029] See also Figure 1 As shown, an embodiment of the utility model provides a rear windshield structure for a loader, including a heat dissipation net assembly 3 and a rear windshield frame assembly 2; the heat dissipation net assembly 3 is installed inside the rear windshield frame assembly 2, and can be opened upward along the upper edge of the rear windshield frame assembly 2.

[0030] like Figure 1 As shown, a gas spring 4 is fixedly arranged between the heat dissipation net assembly 3 and the rear wind window frame assembly 2. When the rear wind window is opened or closed manually, the heat dissipation net assembly 3 only needs to be opened upward or closed downward along the upper edge of the rear wind window frame assembly 2.

[0031] In this embodiment, if Figure 3 As shown, the rear wind window frame assembly 2 includes a rear wind window mounting frame and a rear wind window body 9 adapted to be connected thereto.

[0032] Figure 2 The structure shown is Figure 3 The intuitive structural diagram after hiding the rear window body 9. Figure 2As shown, the rear windshield installation frame includes a panel frame and a flange frame fixedly connected to its periphery, which together constitute the support frame of the rear windshield frame assembly 2 and are used to support and fix the rear windshield body 9.

[0033] The panel frame includes two symmetrically arranged side panels 103, an upper panel 101 connected to the upper ends of the side panels 103 on both sides, and a lower panel 102 connected to the lower ends of the side panels 103 on both sides. The first panel 101 and the lower panel 102 are symmetrical. Specifically, the upper panel 101 is intersected and connected to the upper ends of the side panels 103 on both sides, and the two ends of the lower panel 102 are respectively fixedly connected to the side panels 103 on both sides at a certain distance away from the end points, forming a well-shaped structural frame, but the two ends of the first lower panel 102 do not protrude.

[0034] The outer periphery of the enclosure frame is fixedly connected with a flange frame bent at a certain angle toward the inside of the hood, the flange frame includes an end flange and a side flange, an upper cross beam 104 is provided at the upper end flange, and side beams 105 are respectively provided at the two side flanges. The upper end parts of the side beams 105 on both sides are bent at a certain angle toward the inside of the hood and then fixedly connected to the two ends of the upper cross beam 104 to form a U-shaped structural frame.

[0035] The protruding parts at both ends of the upper panel 101 are bent toward the inside of the hood at a certain angle, and are fixedly connected to the upper ends of the side beams 105 on both sides; the protruding parts at both ends of the side panel 103 are bent toward the inside of the hood at a certain angle, and the upper ends are fixedly connected to the upper cross beam 104. In other words, the panel frame is firmly connected to the flange frame bent at a certain angle on its outer periphery to form a stable frame structure, which provides solid support for the rear window body 9 and can be closely combined with the rear window body 9 to form a whole to jointly withstand external pressure and vibration.

[0036] A plurality of upper reinforcing ribs 106 are fixedly arranged between the upper cross beam 104 and the upper enclosure 101, and the plurality of upper reinforcing ribs 106 are arranged in parallel; a plurality of side reinforcing ribs 107 are fixedly arranged between the side enclosure 103 and the side beam 105, and the plurality of side reinforcing ribs 107 are arranged in parallel; a plurality of lower reinforcing ribs 108 are fixedly arranged at the bottom of the lower enclosure 102, and the plurality of lower reinforcing ribs are arranged in parallel, forming a straight plate structure. Among them, the upper reinforcing ribs 106 and the side reinforcing ribs 107 each have at least one bending portion protruding toward the outside of the hood, and the bending portion forms a preset deformation point for the crushing deformation of the skeleton structure. When the rear windshield structure is compressed and deformed, a controllable deformation trend of the skeleton is created to prevent the skeleton from undergoing unpredictable deformation and causing energy absorption failure.

[0037] like Figure 3 As shown, the rear wind window body 9 is adapted and fixed on the rear wind window mounting frame 1 to form a rear wind window frame assembly 2. The rear wind window frame assembly 2 also provides fixed positions for various components of the rear wind window.

[0038] Specifically: Figure 3 As shown, a rear monitoring mounting plate 109 is fixedly arranged on the rear windshield body 9 between the upper crossbeam 104 and the upper enclosure 101, and hinge reinforcement plates 111 are fixedly arranged on both sides of the rear monitoring mounting plate 109, and a rear windshield upper mounting seat 110 is fixedly arranged at the bottom of the upper crossbeam 104 at a position opposite to the hinge reinforcement plate 111, and a hinge sleeve 112 is fixedly connected below the hinge reinforcement plate 111, and a working light mounting plate 113 is fixedly arranged on one side of the hinge reinforcement plate 111 close to the side enclosure 103. Among them, the rear windshield upper mounting seat 110 and the hinge reinforcement plate 111 are both arranged between the two upper reinforcement ribs 106, the rear windshield upper mounting seat 110 is fixedly arranged at the bottom of the upper crossbeam 104, and the hinge reinforcement plate 111 is fixedly arranged at the top of the upper enclosure 101; the working light mounting plates 113 on both sides are also fixedly arranged at the top of the upper enclosure 101.

[0039] A plurality of rear window side mounting seats 114 are fixedly provided on the inner side of the side beam 105 , and a gas spring lower mounting seat 115 is fixedly provided on the outer side of the side panel 103 . The gas spring lower mounting seat 115 is provided close to the lower panel 102 .

[0040] Preferably, three rear windshield side mounting seats 114 are evenly arranged on the side beam 105, three side reinforcing ribs 107 are evenly arranged between the side beam 105 and the side panel 103, and the rear windshield side mounting seats 114 are matched one by one with the side reinforcing ribs 107. In other words, a rear windshield side mounting seat 114 is arranged at each position of a side reinforcing rib 107, which can effectively utilize the reinforcing effect of the side reinforcing ribs, improve the stability of the mounting seat, and prevent it from being deformed or loosened during use.

[0041] First grooves 116 are provided at both ends of the rear windshield body 9 between the lower panel 102 and the protruding parts of the side panels 103. The first grooves 116 are used to avoid partial structures or protruding structures on the counterweight, ensure the adaptability between the rear windshield frame assembly and the counterweight structure, avoid mutual interference, and thus ensure the integrity and functionality of the entire rear windshield structure.

[0042] This embodiment provides a specific implementation structure of the rear windshield mounting frame 1, which is used to fix and support the rear windshield body 9, ensuring the stability and reliability of the rear windshield body 9. It also provides an implementation method of arranging a rear windshield upper mounting seat 110, a rear windshield side mounting seat 114, a hinge reinforcement plate 111, a work light mounting plate 113, and a gas spring 4 lower mounting seat 115 on the rear windshield mounting frame 1, and fixing a rear monitoring mounting plate 109 on the rear windshield body 9, providing fixed positions for various components of the rear windshield, making the installation process of each component more convenient and efficient, and facilitating the later maintenance and replacement of the components.

[0043] like Figure 1 , Figure 4 , Figure 5As shown, the rear windshield body 9 is welded and fixed on the rear windshield mounting frame 1 to form the rear windshield frame assembly 2. The overall mounting space formed by the rear windshield mounting frame 1 is adapted to the rear windshield body 9, supporting and fixing the rear windshield body 9, so that the rear windshield body 9 can be closely combined with the loader hood, achieving a stable assembly. The rear windshield frame assembly 2 forms a three-dimensional frame energy absorption zone, which can effectively absorb the impact force when the rear of the hood is hit, and plays an important role in protecting the components in the hood.

[0044] The above-mentioned panel frame and the components in the flange frame, the rear windshield mounting frame 1 and the rear windshield body 9 are fixed together by welding or bolt connection; the upper cross beam 104, the upper panel 101, and the lower panel 102 are arranged along the width direction of the loader, and the side beams 105 and the side panels 103 are arranged along the height direction of the loader, together forming the basic shape of the frame.

[0045] Further, the rear windshield frame assembly 2 is connected to the body structure of the loader by a connecting piece, and the connecting piece can be bolts, rivets, welding points, etc., which are not specifically limited in this embodiment and can be selected by technicians according to actual conditions. It should be noted that the specific structure of the rear windshield mounting frame is usually designed according to the design requirements of the loader and the size of the rear windshield, and is compatible with the loader hood.

[0046] In this embodiment, if Figure 6 As shown, the heat dissipation net assembly 3 includes a heat dissipation net enclosure 301 and a heat dissipation net 303 embedded therein. The heat dissipation net enclosure 301 is a rectangular structure with an opening formed therein, and the heat dissipation net 303 adapted thereto is embedded in the opening. In other words, the size and shape of the heat dissipation net 303 are adapted to the opening in the heat dissipation net enclosure 301, and can be embedded therein and fixed.

[0047] The inner and outer surfaces of the heat dissipation net 303 are formed with a plurality of concave and convex rectangular structures in sequence, forming a three-dimensional heat dissipation feature with distinct layers, which significantly increases the heat dissipation area, thereby effectively improving the heat dissipation efficiency. In other words, when viewed from the inner and outer sides of the heat dissipation net 303, a plurality of rectangular protrusions and rectangular depressions are formed on the heat dissipation net 303, and the protrusions and depressions are arranged in sequence, which significantly increases the contact area between the heat dissipation net 303 and the external environment, thereby enhancing the heat dissipation effect.

[0048] like Figure 6 As shown, a door lock 305 is fixedly provided on the lower bottom end of the heat dissipation net enclosure 301, and the door lock 305 cooperates with the lock plate 7 fixed at the corresponding position on the loader hood main beam 5 to lock and fix the heat dissipation net assembly 3 at the rear of the hood to play a safety protection role.

In other words, a reinforcement structure is added around the inner side of the heat dissipation net enclosure 301. The addition of side beams and side reinforcing plates can improve the overall structural strength of the heat dissipation net enclosure 301, so that it can withstand greater external force or pressure and prevent the enclosure from deforming. At the same time, the side beams can also be used as fixing points when installing the heat dissipation plate enclosure, improving the stability and reliability of the installation of the heat dissipation plate or other structures and preventing them from loosening or falling off.

[0050] A gas spring upper mounting seat 309 is fixedly provided at the upper bottom of the side reinforcement plates 302 on both sides, and the gas spring upper mounting seat 309 is a certain distance away from the upper side beam 306; a plurality of upper hinges 304 are fixedly provided on the side of the upper side beam 306, and a hinge welding plate 308 is fixedly provided at the bottom of the upper hinge 304, and the positions of the upper hinge 304 and the hinge welding plate 308 correspond to the positions of the hinge reinforcement plate 111 and the hinge sleeve 112 provided on the rear windshield mounting frame 1, for installation and fixation.

[0051] Lock reinforcement plates 311 are fixedly arranged on both sides of the inner side of the door lock 305 at the bottom end of the heat dissipation mesh plate 301, which are used to improve the rigidity and strength of the area around the door lock 305, effectively resist external impact and vibration, and prevent the door lock 305 from loosening or being damaged.

[0052] like Figure 8 As shown, the heat dissipation net assembly 3 is bent at a certain angle toward the inside of the hood at a certain position away from the bottom end, and is matched with the lower flange portion of the rear windshield frame assembly to adapt to the installation space of the rear windshield frame assembly.

[0053] The overall structure of the rear windshield structure is as follows Figure 1As shown, the rear windshield mounting frame 1 is tightly connected with the rear windshield body 9 to form a rear windshield frame assembly 2, and the rear windshield frame assembly 2 is adaptively connected to the loader hood, and the rear windshield upper fixing seat 10 and the rear windshield side fixing seat 11 fixed on the hood main beam 5 correspond to the rear windshield upper mounting seat 110 and the rear windshield side mounting seat 114 fixed on the rear windshield frame assembly one by one, and are fixedly connected by bolts; the heat dissipation network assembly 3 is installed inside the rear windshield frame assembly 2, and the upper end of the heat dissipation network assembly 3 is fixedly connected to the upper panel 201 of the rear windshield frame assembly 2 through the pin shaft 8, and the heat dissipation network assembly 3 and the two opposite sides of the rear windshield frame assembly 2 are respectively A gas spring 4 is provided, one end of which is fixedly connected to the gas spring upper mounting seat 309 of the side reinforcement plate 302 of the heat dissipation network assembly 3, and the other end is fixedly connected to the gas spring lower mounting seat 115 of the side beam 105 of the rear wind window mounting frame 1, so that the middle heat dissipation network assembly 3 can be opened upward along the upper edge of the rear wind window frame assembly 2; a door lock 305 is provided at the bottom end of the heat dissipation network assembly 3, and a lock plate fixing seat 6 is fixed at the corresponding position of the hood main beam 5 when it is closed, and a lock plate 7 is fixed on the lock plate fixing seat 6, and the lock plate 7 is adapted to the door lock 305, and can be further locked when the heat dissipation network assembly 3 is closed, thereby providing a safety protection function.

[0054] Working principle details:

[0055] First, the rear windshield frame assembly 2 is installed on the loader hood to form a three-dimensional frame energy absorption zone. When the rear of the hood is hit, the energy absorption zone can effectively absorb the impact force and protect the components in the hood. The heat dissipation net assembly 3 is installed inside the rear windshield installation frame assembly, and a gas spring 4 is fixed between the two. When the rear windshield is opened or closed manually, the heat dissipation net assembly 3 can be opened upward or closed downward along the upper edge of the rear windshield frame assembly 2. In this way, the middle heat dissipation net assembly 3 has a small weight, which can reduce the auxiliary force of the human hand when closing the rear windshield, and can also reduce the impact force on the hood frame when closing.

[0056] Although the above describes the specific implementation methods of the utility model in combination with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
