Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery cab technology, and in particular to a cab and a tractor. Background Technology

[0002] To improve tractor visibility and enhance the aesthetics of the cab, four-post tractor cabs typically use tempered glass doors and windshields. However, separate tempered glass doors and windshields not only reduce the cab's aesthetics but also involve various shapes of profiles, often significantly increasing the production cost of the door components. Conversely, one-piece tempered glass doors and windshields place high demands on the overall structural strength of the tempered glass and the installation methods of related accessories. Therefore, it is necessary to provide a cab and tractor that overcomes the aforementioned shortcomings. Utility Model Content

Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0028] See Figures 1 to 5 This embodiment discloses a cab, mainly used in tractors, which includes a body frame 200, a windshield 300, and two door assemblies 100.

[0029] See appendix Figure 1 The vehicle frame 200 is the main frame of the four-post cab. The vehicle frame 200 includes a left front pillar 211, a right front pillar 212, a left rear pillar 221, a right rear pillar (not shown in the figure), a roof 230, a lower floor plate 240, a left mudguard 251, and a right mudguard (not shown in the figure). The windshield 300 is located between the left front pillar 211 and the right front pillar 212. The windshield 300 is a one-piece curved glass with an opening 310 that fits into the tractor's hood 400. Correspondingly, the left front pillar 211 and the right front pillar 212 also have the same curvature as the windshield 300, enabling the installation and fixation of the windshield 300. The two door assemblies 100 are respectively located between the left front pillar 211 and the left rear pillar 221 and between the right front pillar 212 and the right rear pillar door assembly, which can improve the tractor's visibility and highlight the aesthetic design of the cab.

[0030] For ease of description, this embodiment uses the side closer to the driver's cab as the inner side and the side closer to the door assembly 100 for rotation as the pivot side. The door assembly 100 includes: a glass door 1, a hinge assembly, a door lock assembly, a door handle 4, a sunshade device 6, and an armrest assembly 5.

[0031] See appendix Figures 2 to 4 The glass door 1 has a one-piece structure made of tempered glass. On the side of the glass door 1 away from the pivot, there are a first mounting hole 11, a second mounting hole 12, and a third mounting hole 13. The first mounting hole 11 is located at the upper part of the glass door 1, the second mounting hole 12 is located in the middle of the glass door 1, and the third mounting hole 13 is located at the lower part of the glass door 1. The first mounting hole 11, the second mounting hole 12, and the third mounting hole 13 have the same structure. Taking the first mounting hole 11 as an example, the first mounting hole 11 includes a mounting hole formed on the glass door 1 and a flange bolt mounted on the mounting hole.

[0032] See appendix Figure 2 , 3 The hinge assembly includes a mounting base 2 located on the pivot side of the glass door 1 and on the outer side of the glass door 1; a fourth mounting hole 14 located on the mounting base 2 and extending to the inner side of the glass door 1; and a first hinge 21 and a second hinge 22 located on the mounting base 2 and spaced at a predetermined distance. The glass door 1 is mounted on the left rear pillar 221 or the right rear pillar door assembly via the first hinge 21 and the second hinge 22. Since the first hinge 21 and the second hinge 22 are both located on the mounting base 2 and form a single unit, the coaxiality of the glass door 1 during rotation is ensured, avoiding the problem of different torques on the glass door 1 during rotation, which could lead to damage to the tempered glass door 1.

[0033] See appendix Figure 4 The door lock device 3 is fixed on the second mounting hole 12 and located inside the glass door 1. The door lock device 3 is also fixed on the second mounting hole 12 and located inside the glass door 1. The door handle 4 is provided with an unlocking device that is linked to the door lock device 3. The user can unlock the door lock device 3 from the outside of the door assembly 100.

[0034] See appendix Figure 4The armrest assembly 5 is located inside the glass door 1 and is fixed to the first mounting hole 11, the fourth mounting hole 14, the second mounting hole 12, and the third mounting hole 13. The armrest assembly 5 includes an upper support portion 51 provided along the upper edge of the glass door 1, a side support portion 52 provided along the rotating side edge of the glass door 1, a middle support portion 53 provided along the middle of the glass door 1 and extending to the first mounting hole 11, and a lower support portion 54 connected to the middle support portion 53 and extending to the lower part of the glass door 1 to connect the side support portion 52 and the middle support portion 53, and a reinforcing support portion 55. The upper support portion 51, the side support portion 52, and the middle support portion 53 are integrally formed structures and are installed on the glass door 1 through the first mounting hole 11, the fourth mounting hole 14, and the second mounting hole 12, while the lower support portion 54 is installed on the glass door 1 through the third mounting hole 13.

[0035] See appendix Figure 4 The glass door 1 is provided with a fourth mounting hole 14 and a fifth mounting hole 15 along the rotating side edge of the glass door 1. The mounting base 2 is fixed to the glass door 1 through the fourth mounting hole 14 and the fifth mounting hole 15. The fifth mounting hole 15 has the same structure as the first mounting hole 11 and is used to fix the seal 7 by means of a flange nut. The fourth mounting hole 14 is provided with an extension in addition to the flange nut. The flange nut is used to fix the mounting base 2, and the extension is used to fix the side support part 52.

[0036] In addition, a sealing element 7 is provided on the outer edge of the glass door 1. The sealing element 7 is made of elastic materials such as rubber and is fixed to the side edge of the glass door 1 by means of snapping or bonding, so as to play the role of sealing and shock absorption. The fourth mounting hole 14 and the fifth mounting hole 15 can play an auxiliary role in fixing the sealing element 7.

[0037] See appendix Figure 4 , 5 The upper part of the sunshade device 6 is fixedly mounted on the upper support part 51 by flange bolts, and the lower part of the sunshade device 6 is attached to the glass door 1 by suction cups 61, thus providing sunshade. The sunshade device 6 includes a roller 62 fixedly mounted on the upper support part 51, a sunshade 64 wound on the roller 62, and a set of slide rails 63 symmetrically arranged on both sides of the roller 62 and fixed to the glass door 1 by suction cups 61. The free end of the sunshade 64 passes through the roller 62 and can move up and down along the slide rails 63. An operating part 65 is provided at the free end of the sunshade 64. The user can pull the operating part 65 to move the sunshade 64 downward, thus achieving the sunshade effect.

[0038] A first gas spring and a second gas spring are provided between the door assembly 100 and the body frame 200. A first mounting part 511 is provided on the upper support part 51, and a second mounting part 531 is provided on the middle support part 53. A first gas spring is provided between the left rear pillar 221 / right rear pillar door assembly and the first mounting part 511, and a second gas spring is provided between the left rear pillar 221 / right rear pillar door assembly and the first mounting part 511. The first and second gas springs form a dual door damping gas spring, which can support the door assembly 100, reduce the range of motion when the glass is opened or closed, strengthen the fixation of the glass door 1, and reduce the risk of glass breakage. Moreover, the dual door damping gas spring can also reduce the risk of gas spring failure, as the failure of one does not affect the use of the other.

[0039] It will be apparent to those skilled in the art that various modifications and variations can be made to the exemplary embodiments of the present invention without departing from the spirit and scope of the present invention. Therefore, it is intended that the present invention cover modifications and variations falling within the scope of the appended claims and their equivalents.
