Description

Technical Field

[0002] A combine harvester is a machine that integrates harvesting of crops. It can complete the harvesting, threshing, and collection of grains into a storage bin in one operation.

[0003] Combination Figure 1 As shown, most existing harvesters use a mechanical motion transmission structure 1' (which includes a U-shaped control handle and a connecting rod) to control steering and header lifting. However, the existing mechanical motion transmission structure occupies a large space, and the U-shaped control handle and the corresponding hydraulic valve must be very close together, which makes the placement difficult.

For example, the order of operations described herein is merely illustrative and is not limited to the order set forth herein; changes that will be apparent after understanding the disclosure of this application are possible, except for operations that must occur in a specific order. Furthermore, for clarity and brevity, descriptions of features known in the art may be omitted.

[0053] The features described herein may be implemented in different forms and should not be construed as being limited to the examples described herein. Rather, the examples described herein have been provided merely to illustrate some of the many feasible ways of implementing the methods, apparatus, and / or systems described herein that will be apparent upon understanding the disclosure of this application.

[0054] Throughout the specification, when an element (such as a layer, region, or substrate) is described as being "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, it may be directly "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, or there may be one or more other elements in between. In contrast, when an element is described as being "directly on" another element, "directly connected to" another element, "directly bonded to" another element, "directly on" another element, or "directly covering" another element, there may be no other elements in between.

[0055] As used herein, the term “and / or” includes any one of the relevant items listed and any combination of any two or more items.

[0056] Although terms such as “first,” “second,” and “third” may be used herein to describe individual components, assemblies, regions, layers, or parts, these components, assemblies, regions, layers, or parts are not limited by these terms. Rather, these terms are used only to distinguish one component, assembly, region, layer, or part from another. Therefore, without departing from the teachings of the examples described herein, the first component, assembly, region, layer, or part referred to as the second component, assembly, region, layer, or part may also be referred to as the second component, assembly, region, layer, or part.

Therefore, the term “above” includes both “above” and “below” orientations depending on the spatial orientation of the device. The device may also be positioned in other ways (e.g., moved 90 degrees or in other orientations), and the spatial relation terms used herein will be interpreted accordingly.

Furthermore, although the examples described herein have a wide variety of constructions, other constructions are possible, as will be apparent upon understanding the disclosure of this application.

[0061] Example 1

[0062] This application provides an electrically controlled handle structure. This electric handle structure uses an operating lever 5 combined with an angle sensor to convert mechanical operation into electrical signals. It eliminates the need for a central connecting structure, resulting in a small footprint and light weight for the entire device. The following describes... Figure 1 and Figure 2 This application provides a detailed description of an electronically controlled handle structure.

[0063] The electric control handle structure includes an angle sensor, and there are two angle sensors; the axes of the two angle sensors are perpendicular to each other; for ease of explanation, the following is an example of having two angle sensors, and will be explained in detail below; the two angle sensors are the first angle sensor 1 and the second angle sensor 2.

[0064] The electric control handle structure also includes a transmission assembly 6, which has multiple connection points, with at least two connection points having axes perpendicular to each other. For ease of explanation, the following description uses two connection points as an example; the two connection points are the first connection point 3 and the second connection point 4. Specifically, the axes of the first connection point 3 and the second connection point 4 are perpendicular to each other. The first connection point 3 is connected to the first angle sensor 1, and the second connection point 4 is connected to the second angle sensor 2. That is to say, the axis of the first angle sensor 1 is perpendicular to the axis of the second angle sensor 2.

[0065] The electric control handle structure also includes an operating lever 5; the operating lever 5 is connected to the transmission assembly 6; when the operating lever 5 is driven along the first direction 7 (here the first direction 7 is combined with...), the structure also includes an operating lever 5; the operating lever 5 is connected to the transmission assembly 6; when the driving operating lever 5 moves along the first direction 7, the first direction 7 is combined with... Figure 2 As shown, when the first connection point 3 rotates (referring to the rotation direction around the first axis 42), it can simultaneously rotate along the first direction 7. Since the first connection point 3 is connected to the first angle sensor 1, when the first connection point 3 rotates, the first angle sensor 1 can detect the rotation angle of the first connection point 3. In actual use, the first angle sensor 1 is electrically connected to the controller on the harvester. The controller (which is built into the harvester and is understood by those skilled in the art, so it will not be elaborated here; the controller and the angle sensor are connected by wires. This application does not improve its own program, but only connects the two together by wires, and they still perform their original functions) can convert the angle detected by the first angle sensor 1 into an electrical signal, that is, it can convert the mechanical rotation signal of the first direction 7 output by the operating lever 5 into an electrical rotation signal of the first direction 7. Similarly, when the operating lever 5 rotates along the second direction 8 (here, the second direction 8 is combined with...) Figure 2 As shown, when rotating around the second axis 43, the second connection point 4 can simultaneously rotate along the second direction 8. Since the second connection point 4 is connected to the second angle sensor 2, the second angle sensor 2 can detect the rotation angle of the second connection point 4 when it rotates. In actual use, the second angle sensor 2 is electrically connected to the controller on the harvester. The controller can convert the angle detected by the second angle sensor 2 into an electrical signal, that is, it can convert the mechanical rotation signal of the second direction 8 output by the operating lever 5 into an electrical rotation signal of the second direction 8.

[0066] It is worth noting that in actual use, the first direction 7 can refer to the front-back or left-right direction of the harvester, and the second direction 8 can refer to the left-right or front-back direction of the harvester.

[0067] In summary, this application utilizes a combination of the operating lever 5, the transmission component 6, and the angle sensor to convert mechanical operations into electrical signals. The absence of a central connecting structure results in a small footprint and lightweight device.

[0068] In this embodiment, combined with Figure 2 See also Figure 3 As shown, the transmission assembly 6 includes a support frame 9, a first direction transmission component 10, and a second direction transmission component 11.

[0069] Specifically, the first direction transmission member 10 has a first limiting hole 13 extending along a third direction 12 and a first output portion 14 extending along a third direction 12; the second direction transmission member 11 has a second limiting hole 16 extending along a fourth direction 15, a second output portion 17 extending along a fourth direction 15, and a rotating shaft portion 18 extending along a third direction 12; combined Figure 2 As shown, the third direction 12 refers to the left-right direction in the figure, and the fourth direction 15 refers to the front-back direction in the figure. That is, the first limiting hole 13 extends along the left-right direction, and the second limiting hole 16 extends along the front-back direction. Furthermore, the third direction 12 is perpendicular to the fourth direction 15, which means that the axis of the first limiting hole 13 is perpendicular to the axis of the second limiting hole 16. Even further, both the first limiting hole 13 and the second limiting hole 16 are oblong holes, and they respectively have clearance fit with the operating rod 5.

[0070] Specifically, the first output part 14 passes through the support frame 9 and is connected to the first angle sensor 1. The first output part 14 has a first connection point 3 formed on the part that passes through the support frame 9. Since the first connection point 3 is connected to the first angle sensor 1, it can be seen that the first angle sensor 1 is located outside the support frame 9.

[0071] Specifically, the second output part 17 passes through the support frame 9 and is connected to the second angle sensor 2, and the second output part 17 has a second connection point 4 formed on the part passing through the support frame 9; since the second connection point 4 is connected to the second angle sensor 2, it can be seen that the second angle sensor 2 is disposed outside the support frame 9.

[0072] Specifically, the operating lever 5 is connected to the rotating shaft 18 at a preset position, and the bottom of the operating lever 5 passes through the second limiting hole 16 and the first limiting hole 13 in sequence. Since the axes of the first limiting hole 13 and the second limiting hole 16 are perpendicular, when the operating lever 5 rotates along the first direction 7, the bottom of the operating lever 5 will move freely in the second limiting hole 16 and can drive the first direction transmission component 10 to rotate along the first direction 7. Similarly, when the operating lever 5 rotates along the second direction 8, the bottom of the operating lever 5 will move freely in the first limiting hole 13 and can drive the second direction transmission component 11 to rotate along the second direction 8.

[0073] In this embodiment, combined with Figure 3 As shown, the first directional transmission member 10 includes a first connecting frame 19 and a first output shaft 20 that can serve as a first output part 14. Specifically, a support frame 9 surrounds a first mounting space 21, and the first directional transmission member 10 is disposed in the first mounting space 21. The first output shaft 20 is disposed on the side wall of the first connecting frame 19 facing the support frame 9, and the first output shaft 20 extends along a third direction 12 and passes through the support frame 9. A first connection point 3 is formed on the first output shaft 20 passing through the support frame 9 and is connected to a first angle sensor 1. A first limiting hole 13 is disposed on the bottom wall of the first connecting frame 19. Preferably, the first connection point 3 is formed at the end of the first output shaft 20 passing through the support frame 9, and the first angle sensor 1 is fixedly connected to the first output shaft 20.

[0074] Furthermore, combined Figure 3 As shown, the first connecting frame 19 extends along the third direction 12. The first connecting frame 19 includes a first side plate 22, a second side plate 23, and a third side plate 24. The first side plate 22, the second side plate 23, and the third side plate 24 are connected in sequence to form a U-shape and surround a second mounting space 25. The first output shaft 20 is disposed on the third side plate 24 and extends along the third direction 12. The first limiting hole 13 is opened on the second side plate 23 and extends along the third direction 12.

[0075] Furthermore, combining Figure 3As shown, the first side plate 22 includes a first segment 26 and a second segment 27 connected in sequence; the first segment 26 and the second segment 27 are at a first preset angle, and the second segment 27 is connected to the second side plate 23 at a second preset angle; the first limiting hole 13 starts from the second segment 27 and extends to the second side plate 23 along the third direction 12. When the operating lever 5 rotates along the second direction 8, the bottom of the operating lever 5 will move freely in the first limiting hole 13. Note that since the first limiting hole 13 starts from the second segment 27 and extends to the second side plate 23 along the third direction 12, the bottom of the operating lever 5 will move freely on the second segment 27 and the second side plate 23. In this way, the swing angle of the operating lever 5 is increased, and the second angle sensor 2 can be used to convert a second direction electric rotation signal with a wider vertical range.

[0076] Preferably, since the electric control handle structure developed in this application is applied to a harvester, considering the limited installation space of the harvester, the first preset angle is preferably set to 135° and the second preset angle is preferably set to 135°; that is, the first segment 26 and the second side plate 23 are not vertically connected, but are connected by the oblique second segment 27; that is, due to the presence of the second segment 27, an avoidance gap is formed between the first segment 26 and the second side plate 23, which precisely solves the problem of limited installation space of the harvester.

[0077] In this embodiment, combined with Figure 2 As shown, the second direction transmission member 11 includes a second connecting frame 28, a second output shaft 29 that can serve as a second output part 17, and a rotating shaft 30 that can serve as a rotating shaft part 18. Specifically, the second direction transmission member 11 is disposed in the second mounting space 25; the second output shaft 29 is disposed on the side wall of the second connecting frame 28 facing the support frame 9, and the second output shaft 29 extends along the fourth direction 15 and passes through the support frame 9; a second connection point 4 is formed on the second output shaft 29 passing through the support frame 9 and is connected to the second angle sensor 2; a second limiting hole 16 is disposed on the bottom wall of the second connecting frame 28; the rotating shaft 30 is disposed on the second connecting frame 28 and extends along the third direction 12, and the operating lever 5 is fixed to the rotating shaft 30 by a connector 41 and can rotate around the rotating shaft 30 in the first direction 7. Preferably, the second connection point 4 is formed at the end of the second output shaft 29 passing through the support frame 9, and the second angle sensor 2 is fixedly connected to the second output shaft 29.

[0078] Furthermore, the second connecting frame 28 extends along the fourth direction 15 as a whole; the second connecting frame 28 includes a fourth side plate 31, a fifth side plate 32, a sixth side plate 33, and a seventh side plate 34; the fourth side plate 31, the fifth side plate 32, and the sixth side plate 33 are connected sequentially to form a U-shaped structure; the seventh side plate 34 is disposed on one side of the U-shaped structure along the third direction 12, so that the seventh side plate 34 and the U-shaped structure enclose a third mounting space 35; the operating rod 5 is located in the third mounting space 35, and the rotating shaft 30 extends along the third direction 12 and passes through the operating rod 5;

[0079] The second limiting hole 16 is provided on the fifth side plate 32 and extends along the fourth direction 15, and the second output shaft 29 is provided on the sixth side plate 33 and extends along the fourth direction 15.

[0080] In this embodiment, combined with Figure 3 As shown, the support frame 9 includes an eighth side plate 36, a ninth side plate 37, and a tenth side plate 38; the eighth side plate 36, the ninth side plate 37, and the tenth side plate 38 are connected in sequence to form a U-shaped structure to enclose the first installation space 21.

[0081] Furthermore, the opening of the support frame 9 faces to the left, the opening of the first connecting frame 19 faces upward, and the opening of the second connecting frame 28 faces upward and to the right; even further, the third side plate 24 is close to the ninth side plate 37, and the first side plate 22 is away from the ninth side plate 37; the fourth side plate 31 is close to the eighth side plate 36, the sixth side plate 33 is away from the eighth side plate 36, the seventh side plate 34 is opposite to the ninth side plate 37, and the fifth side plate 32 is located above the second side plate 23, that is, the second limiting hole 16 is located above the first limiting hole 13. Therefore, combined with... Figure 2 As shown, the supporting frame 9 encloses the first connecting frame 19, and the manufacturing frame and the first connecting frame 19 together enclose the second connecting frame 28.

[0082] Furthermore, the eighth side plate 36 has a first through hole 39, through which the second output shaft 29 passes and is connected to the second angle sensor 2; the ninth side plate 37 has a second through hole 40, through which the first output shaft 20 passes and is connected to the first angle sensor 1.

[0083] In actual use, when the operating lever 5 rotates along the first direction 7, the bottom of the operating lever 5 will move freely within the second limiting hole 16. Since the extension directions of the first limiting hole 13 and the second limiting hole 16 are perpendicular, the operating lever 5 can forcibly drive the first direction transmission component 10 to rotate along the first direction 7. Similarly, when the operating lever 5 rotates along the second direction 8, the bottom of the operating lever 5 will move freely within the first limiting hole 13 and can forcibly drive the second direction transmission component 11 to rotate along the second direction 8.

[0084] In summary, this application, through the special structure of the first transmission component and the second transmission component and their mutual cooperation, enables the first angle sensor 1 to convert the mechanical rotation signal in the first direction 7 into an electrical rotation signal in the first direction 7, and the mechanical rotation signal in the second direction 8 into an electrical rotation signal in the second direction 8; moreover, the electrical rotation signal in the first direction 7 and the electrical rotation signal in the second direction 8 are generated independently, without any interference between them; that is to say, this application uses an angle sensor to replace the traditional linkage structure, which occupies less space, is lighter, and is easier to arrange.
