[0041] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.
[0042] Wheat harvesting operations are often time-sensitive and demanding, and drivers may need to work continuously for a long time. Therefore, it is necessary to allow the driver to get enough rest during the work intervals to restore physical strength and energy, thereby ensuring the safety and efficiency of the operation. Based on this, the present embodiment provides a folding bed in the cab of a harvester.
[0043] like Figures 1 to 5 As shown, the folding bed comprises a foldable bed frame 9 and a plurality of supporting structures;
[0044] The foldable bed frame 9 includes at least two bed frame modules that can be folded relative to each other. Two adjacent bed frame modules are connected by hinges, so that the foldable bed frame can form a flat frame after being unfolded.
[0045] In this embodiment, the foldable bed frame 9 includes a first bed frame module 10, a second bed frame module 13 and a third bed frame module 14; the hinge 12 between the first bed frame module 10 and the second bed frame module 13 is located on the lower surface of the foldable bed frame 9 (i.e., the side facing the floor of the harvester cab 2 when unfolded); the hinge 12 between the second bed frame module 13 and the third bed frame module 14 is located on the upper surface of the foldable bed frame 9 (i.e., the side facing the ceiling of the harvester cab 2 when unfolded). The design of the three-section bed frame module makes the space occupied by the foldable bed frame 9 smaller after folding, and the thickness is moderate, which is convenient for storage. In addition, after the foldable bed frame 9 is unfolded, the third bed frame module 14 can be flipped upward relative to the second bed frame module 13, so as to facilitate the closing of the cab door.
[0046] The supporting structure includes a supporting frame 11 and supporting legs 16; the supporting frame 11 is arranged on a long side of the foldable bed frame 9, and is used to support on the co-pilot guardrail 4 of the harvester cab; there are at least three supporting legs 16, which are respectively arranged on at least two sides of the foldable bed frame 9, and are used to support on the floor of the harvester cab 2.
[0047] Specifically, the support frame 11 is a plurality of parallel ones, and is connected to the foldable bed frame 9 by welding; it is short in length, and a notch is provided at the outer end for overlapping with the co-pilot guardrail 4. The notch is preferably an arc-shaped opening, so as to be more closely fitted and more firmly supported on the co-pilot guardrail 4.
[0048] In this embodiment, there are three support frames 11 arranged at intervals, all of which are welded to the side of the first bed frame module 10. Since the co-pilot guardrail 4 itself has a certain height, the length of the support frame 11 is generally within 10 cm.
[0049] To reduce the space occupied after storage, the support leg 16 is rotatably connected to the foldable bed frame 9.
[0050] To further facilitate storage, when the support leg 16 is telescopically connected, specifically, it includes two short legs inserted into each other. A number of insertion holes are arranged on the side wall of the outer short leg along the length direction of the short leg, and an elastic pin is provided on the inner short leg. During use, it can be adjusted according to the height of each position on the floor of the harvester cab 2 so that the bed surface of the unfolded folding bed 1 is basically horizontal.
[0051] To make the unfolded folding bed 1 more stable and also to facilitate use and storage, in this embodiment, a support leg 16 is provided on the lower surface of the first bed frame module 10, and the support leg 16 and the support frame 11 are respectively located on two long sides of the first bed frame module 10. A support leg 16 is respectively provided on two long sides of the second bed frame module 13.
[0052] Generally, no support leg is provided on the third bed frame module 14 to avoid affecting the upward flipping movement of the third bed frame module 14. In this way, sufficient standing space can be provided for the user when closing the cab door. After closing the door, the third bed frame module 14 can be placed on the main driver's armrest 5 to increase the length of the entire bed body and ensure that the user has enough space to rest.
[0053] In other embodiments, the short legs can also be detachably connected by threads, plug-and-play detachable connection methods, etc.
[0054] In a preferred embodiment, the folding bed further includes a number of support blocks 8, which are arranged on the short sides of the first bed frame module 10 for lapping with the co-driver's armrest 6 of the harvester cab 2.
[0055] Multiple support blocks 8 can also be added on the third bed frame module 14 for lapping with the main driver's armrest 5 of the harvester cab 2.
[0056] In a preferred embodiment, the support frame 11 is arranged outside the first bed frame module 10 and is generally in an "L" shape, so as to facilitate supporting on the co-driver's guardrail 4 and also avoid the folding bed 1 being too close to the front windshield of the harvester cab 2. The support leg 16 is arranged on the lower surface of the foldable bed frame 9; when the support leg 16 is bent and attached to the foldable bed frame 9, the support frame 11 can be staggered from the support leg 16 to avoid interference.
[0057] In a preferred embodiment, horizontal support bars are provided inside the first bed frame module 10, the second bed frame module 13, and the third bed frame module 14 to improve the support of the folding bed 1.
[0058] It also includes a mattress 15 for laying on the foldable bed frame 9. The mattress preferably uses nylon material with good breathability, comfort, toughness and lightness.
[0059] In a preferred embodiment, anti-slip rubber sleeves 17 are respectively provided at the ends of the support legs 16, which can further ensure the stability of the folding bed 1.
[0060] In this embodiment, a harvester is also provided. A co-driver safety railing 4 is provided inside the front windshield of the harvester cab 2, and a main driver armrest 6 and a co-driver armrest 5 are respectively provided on the main driver door and the co-driver door of the harvester cab 2;
[0061] As Figures 1 to 3 shown, when the folding bed 1 is unfolded for use, the support frame 11 is supported on the co-driver safety railing 4, the support block 8 is lapped on the co-driver armrest 5, and the support legs 16 are supported on the floor of the harvester cab 2.
[0062] To improve safety and avoid the situation that the harvester is accidentally started when the user is resting after placing the folding bed 1, a sensor 3 is also provided above the co-driver safety railing 4 in this embodiment, which is used to detect whether the support frame 11 is supported on the co-driver safety railing 4; and, the sensor 3 is electrically connected to the ECU of the harvester, and the ECU of the harvester can simultaneously obtain the gear signal of the operation handle of the harvester and the start signal of the harvester.
[0063] As Figure 6 shown, when the folding bed 1 is not placed and the operation handle is in the middle position, when the start button is pressed, the sensor signal, the handle middle position signal and the start signal are transmitted to the ECU through hard wire. When the ECU receives the signal, the vehicle starts successfully; when the folding bed 1 is placed, the sensor 3 has no signal. At this time, even if the operation handle is in the middle position and the start button is pressed, only the handle middle position signal and the start signal are transmitted to the ECU through hard wire, and the vehicle cannot start. Therefore, the driver cannot start the vehicle when the folding bed 1 is properly placed, ensuring safety.
[0064] The sensor 3 can adopt a photoelectric sensor, which is arranged above the co-driver safety railing 4 and can emit light towards the installation position of the support frame 11 to detect whether the support frame 11 exists.
[0065] The solution of this embodiment can bring the following effects:
[0066] ① Improve comfort: Provide a relatively comfortable sleeping environment for the driver, which helps to relieve physical fatigue and improve the comfort and satisfaction of work;
[0067] ② Enhance the continuity of operation: Enable the driver not to leave the cab to find a rest place, reduce the time of operation interruption, and improve the working efficiency and progress of wheat harvesting;
[0068] ③ Facilitate operation and quick conversion: The design should ensure that the unfolding and folding operations of the sleeping bed are simple and fast, and the state conversion can be completed within a short time to adapt to the rhythm of the operation;
[0069] ④ Improve safety: Add sensors to prohibit starting the vehicle during the driver's rest period.
[0070] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
