Furthermore, the large number of pillars limits the driver's field of vision, sometimes preventing them from effectively observing the working environment, which undoubtedly has a negative impact on work efficiency and safety. Utility Model Content

[0003] The purpose of this application is to provide a cab for an operating machine and an operating machine, which can improve the convenience of the driver entering and exiting the cab and effectively expand the driver's field of vision.

[0004] In order to achieve the above objectives, the present application provides, on one hand, a cab for a working machine, comprising:

[0005] The frame comprises a first front pillar, a first rear pillar, a second rear pillar, and a second front pillar arranged in sequence along a circumferential direction, a first side opening being formed between the first front pillar and the first rear pillar, a second side opening being formed between the second front pillar and the second rear pillar, and a rear opening being formed between the first rear pillar and the second rear pillar;

[0006] a transparent side door connected to the frame and capable of opening and closing the first side opening;

[0007] a transparent side panel connected to the frame and closing the second side opening; and

[0008] A transparent back door is connected to the frame and can open and close the rear opening.

[0009] In some embodiments, the transparent side door and / or the transparent back door is formed as a flip door that can be flipped open and closed, and the flip door is connected to the frame via a C-shaped hinge.

[0010] In some embodiments, the flip door is connected to the C-shaped hinge via a clip-through structure, and the clip-through structure includes:

[0011] a fixing sleeve, wherein the inner end of the fixing sleeve abuts against the surface of the C-shaped hinge;

[0012] a first elastic pad, which is externally mounted on the fixing sleeve, wherein the inner end of the first elastic pad abuts against the surface of the C-shaped hinge;

[0013] a second elastic pad, which is externally mounted on the fixing sleeve, wherein the inner end of the second elastic pad abuts against the outer end of the first elastic pad, and the flip door is sandwiched between the first elastic pad and the second elastic pad;

[0014] a gasket abutting against an outer end of the second elastic pad;

[0015] A connecting piece connects the gasket, the fixing sleeve and the C-shaped hinge in sequence from the outside to the inside, and the outer end of the connecting piece is provided with a pressing portion for pressing the gasket inward.

[0016] In some embodiments, the frame further comprises a first side enclosing structure, a second side enclosing structure, and a rear enclosing structure respectively enclosing the first side opening, the second side opening, and the rear opening, and the transparent side door, the transparent side panel, and the transparent back door are respectively connected to the first side enclosing structure, the second side enclosing structure, and the rear enclosing structure;

[0017] Among them, multi-foam sealing strips are sealed between the transparent side door and the first side enclosure structure, between the transparent side panel and the second side enclosure structure, and between the transparent back door and the rear enclosure structure.

[0018] In some embodiments, the multi-foam sealing strip includes a foam body serial connection structure and an elastic clip structure, wherein the foam body serial connection structure includes a plurality of foam bodies serially connected in sequence, and the elastic clip structure is formed with a clip groove;

[0019] Wherein, two ends of the foam body serial connection structure are respectively connected to the elastic snap-fit ​​structure and the corresponding enclosing structure in the frame, and the corresponding transparent structure is inserted and fixed in the snap-fit ​​groove.

[0042] The following describes the specific embodiments of the present application in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present application and are not intended to limit the present application.

[0043] Reference Figures 1 to 5 A first exemplary embodiment of the present application provides a cab for a working machine, comprising:

[0044] The frame comprises a first front column, a first rear column, a second rear column, and a second front column arranged in sequence along a circumferential direction, a first side opening being formed between the first front column and the first rear column, a second side opening being formed between the second front column and the second rear column, and a rear opening being formed between the first rear column and the second rear column;

[0045] a transparent side door 102 connected to the frame and capable of opening and closing the first side opening;

[0046] a transparent side panel 302 connected to the frame and closing the second side opening; and

[0047] The transparent back door 202 is connected to the frame and can be opened and closed.

[0048] Through the above-mentioned arrangement, compared with the existing six-pillar cab, the cab of the present application has a wider spacing between two adjacent columns due to the reduction in the number of columns, while the overall size of the cab remains unchanged. Therefore, the first side opening, the second side opening and the rear opening are all relatively spacious, which makes it easier for the driver to enter and exit the cab normally from the first side opening by opening the transparent side door 102, and easier for the driver to escape from the rear opening by opening or destroying the transparent back door 202, and easier for the driver to escape from the second side opening by destroying the transparent side panel 302. In other words, it can improve the convenience of entering and exiting the cab overall.

[0049] In addition, when the transparent back door 202 is opened during normal operation, the wider rear opening is more conducive to improving the air circulation and heat dissipation in the cab, thereby improving the driver's comfort and driving experience.

[0050] Furthermore, the reduction in the number of pillars and the large-area transparent structure of the transparent side doors 102, transparent side panels 302 and transparent back door 202 can effectively expand the driver's field of view, reduce the situation where he cannot effectively observe the working environment, and help improve work efficiency and work safety.

[0051] It should be noted that the present application does not limit the specific transparent materials used for the transparent side door 102, the transparent side panel 302 and the transparent back door 202, such as glass, polycarbonate, acrylic, polystyrene, polymethyl methacrylate, etc., which can be selected according to actual needs.

[0052] In some embodiments, the transparent side door 102 and / or the transparent back door 202 are formed as flip doors that can be flipped open and closed, and the flip doors are connected to the frame via C-shaped hinges. Figure 1 When the transparent side door 102 is a flip door, the transparent side door 102 can be hinged to the frame through the first C-shaped hinge 104, so that the transparent side door 102 can flip open and close the first side opening.

[0053] Since the first side opening and the rear opening of the cab of the present application are relatively spacious, the sizes of the transparent side door 102 and the transparent back door 202 are also correspondingly larger. In order to ensure the rigidity and strength of the door body, this embodiment uses a larger C-shaped hinge to connect the door body and the frame, thereby improving the opening and closing stability and durability of the door body.

[0054] Furthermore, the flip door and the corresponding C-shaped hinge can be connected through a clamping and connecting structure. Figure 5 , the clamp-through structure may include:

[0055] a fixing sleeve 107, wherein the inner end of the fixing sleeve 107 abuts against the surface of the C-shaped hinge;

[0056] A first elastic pad 106 is externally mounted on the fixing sleeve 107, and an inner end of the first elastic pad 106 abuts against the surface of the C-shaped hinge;

[0057] The second elastic pad 109 is externally mounted on the fixing sleeve 107 , and the inner end of the second elastic pad 109 abuts against the outer end of the first elastic pad 106 , with the aforementioned flip door being sandwiched between the first elastic pad 106 and the second elastic pad 109 ;

[0058] The gasket 105 abuts against the outer end of the second elastic pad 109;

[0059] The connecting piece 108 sequentially connects the gasket 105 , the fixing sleeve 107 and the C-shaped hinge from the outside to the inside, and the outer end of the connecting piece 108 is provided with a pressing portion for pressing the gasket 105 inward.

[0060] By setting up the above-mentioned clamping and connecting structure, the flip door can be stably clamped between the first elastic pad 106 and the second elastic pad 109, which not only ensures the installation stability, assembly accuracy and matching accuracy of the door body and the C-shaped hinge, but also prevents the flip door from being damaged by clamping. Especially when the flip door adopts a glass structure, the above-mentioned clamping and connecting structure can effectively reduce the chance of glass breakage and improve the durability of the door body.

[0061] Furthermore, each component of the aforementioned clamp-and-through connection structure can be made of readily available materials or readily produced components, facilitating installation and effectively controlling costs. For example, the first elastic pad 106 and the second elastic pad 109 can be rubber pads, the fixing sleeve 107 can be a steel sleeve, and the through-connector 108 can be a hexagon socket flange bolt.

[0062] Reference Figure 1 When the transparent side door 102 adopts a flip door, it can be set as a horizontal flip door that can be flipped open and closed horizontally; and / or, when the transparent back door 202 adopts a flip door, it can be set as an up-down flip door that can be flipped open and closed up and down.

[0063] Of course, the present application does not limit the specific flipping and opening and closing directions of the transparent side door 102 and the transparent back door 202, which can be set according to actual usage needs.

[0064] In some embodiments, when any one of the transparent side door 102, the transparent side panel 302 and the transparent back door 202 adopts a glass structure, considering the large sizes of the transparent side door 102, the transparent side panel 302 and the transparent back door 202, and considering factors such as sound insulation and the difficulty of breaking windows to escape, the thickness of the glass structure can be set to 4 mm to 7 mm.

[0065] For example, when the transparent side door 102 adopts a glass structure, the thickness of the transparent side door 102 can be set to 6 mm; when the transparent side panel 302 adopts a glass structure, the thickness of the transparent side panel 302 can be set to 5 mm; when the transparent back door 202 adopts a glass structure, the thickness of the transparent back door 202 can be set to 5 mm.

[0066] In some embodiments, the glass structure may adopt a green wave glass structure; and / or, the glass structure may adopt an anti-ultraviolet heat-insulating glass structure, so as to improve the heat insulation and ultraviolet protection effects of the glass structure, thereby improving the comfort of the driver.

[0067] In some embodiments, the glass structure has an ultraviolet blocking rate of not less than 99%, and more preferably, an ultraviolet blocking rate of not less than 99.5%; and / or, the glass structure has an infrared blocking rate of not less than 80%, and more preferably, an infrared blocking rate of not less than 82.5%; and / or, the glass structure has a light transmittance of not less than 70%.

[0068] In some embodiments, the frame further comprises a first side enclosure structure 103, a second side enclosure structure 303, and a rear enclosure structure 203, which respectively enclose a first side opening, a second side opening, and a rear opening. The transparent side door 102, the transparent side panel 302, and the transparent back door 202 are respectively connected to the first side enclosure structure 103, the second side enclosure structure 303, and the rear enclosure structure 203. In addition, multi-bubble sealing strips (e.g., double-bubble sealing strips, triple-bubble sealing strips, etc.) are hermetically connected between the transparent side door 102 and the first side enclosure structure 103, between the transparent side panel 302 and the second side enclosure structure 303, and between the transparent back door 202 and the rear enclosure structure 203.

[0069] In some embodiments, the multi-foam sealing strip includes a foam body serial connection structure and an elastic snap-fit ​​structure, wherein the foam body serial connection structure includes a plurality of foam bodies serially connected in sequence, and the elastic snap-fit ​​structure forms a snap-fit ​​groove. In addition, the two ends of the foam body serial connection structure are respectively connected to the elastic snap-fit ​​structure and the corresponding enclosure structure in the frame (i.e., the first side enclosure structure 103, the second side enclosure structure 303, or the rear enclosure structure 203), and the snap-fit ​​groove of the elastic snap-fit ​​structure is plugged and fixed with a corresponding transparent structure (i.e., the transparent side door 102 corresponding to the first side enclosure structure 103, the transparent side panel 302 corresponding to the second side enclosure structure 303, or the transparent back door 202 corresponding to the rear enclosure structure 203).

[0070] More specifically, for example, referring to Figure 1 and Figure 2 The transparent side door 102 and the first side enclosure structure 103 can be sealed with a first side sealing strip 101 having a multi-bubble sealing structure. Figure 1 and Figure 3The transparent back door 202 and the rear enclosure structure 203 can be sealed with a rear sealing strip 201 having a multi-bubble sealing structure. Figure 1 and Figure 4 A second side sealing strip 301 having a multi-bubble sealing structure can be used to seal the transparent side panel 302 and the second side enclosing structure 303 .

[0071] By adopting multi-bubble sealing strips, the sealing between the transparent side door 102 and the first side enclosure structure 103, between the transparent side panel 302 and the second side enclosure structure 303, and between the transparent back door 202 and the rear enclosure structure 203 can be ensured, effectively improving the sound insulation, dust and pollution prevention effects of the cab.

[0072] When the transparent side door 102 opens the first side opening, the first side sealing strip 101 is out of contact with the first side enclosure structure 103; when the transparent side door 102 closes the first side opening, the first side sealing strip 101 is sealed and connected to the first side enclosure structure 103, and the multi-bubble structure can play a good door closing buffering effect.

[0073] Similarly, when the transparent back door 202 is opened, the rear sealing strip 201 is out of contact with the rear enclosure structure 203; when the transparent back door 202 is closed, the rear sealing strip 201 is sealed and connected to the rear enclosure structure 203, and the multi-bubble structure can play a good door closing buffering effect.

[0074] In addition, the second exemplary embodiment of the present application further provides a working machine, which includes the above-mentioned cab for the working machine. For example, the working machine of the present application includes but is not limited to a tractor, a truck crane, a truck-mounted crane, etc.
