Description

Technical Field

[0001] This utility model relates to the field of engineering machinery technology, and in particular to seat components and engineering machinery. Background Technology

[0002] Construction machinery operators have increasingly higher requirements for comfort during work. The seats and surrounding structures of construction machinery (such as armrests) have a significant impact on operator comfort. In traditional solutions, the position of the seats of construction machinery can be adjusted by sliding or rotating, while the position of the armrests is fixed.

[0003] To address this, a related technology provides a multi-angle adjustment mechanism for the armrest box, which includes a lockable gas spring. One end of the lockable gas spring is connected to the seat frame, and the other end is connected to the armrest box housing. This allows the lockable gas spring to drive the armrest box housing to rotate steplessly around a pivot, ensuring the operating comfort of users of different body types and sitting postures. However, the problem is that the adjustment and locking of the armrest box position relies on the lockable gas spring, thus requiring a release device, pull cable, and other devices, resulting in a complex structure and high installation costs.

[0040] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0041] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0042] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0043] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0044] Related technology provides a multi-angle adjustment mechanism for an armrest box, which is equipped with a lockable gas spring. One end of the lockable gas spring is connected to the seat frame, and the other end is connected to the armrest box shell, allowing the lockable gas spring to drive the armrest box shell to rotate steplessly around a pivot, ensuring the operating comfort of operators of different body types and sitting postures. However, the problem is that the adjustment and locking of the armrest box position relies on the lockable gas spring, thus requiring the addition of a release device, pull cable, and other devices, resulting in a complex structure and high installation cost.

[0045] In response, this embodiment provides a seat assembly to solve the problem that the multi-angle adjustment mechanism of the armrest box has a complex structure and high installation cost in the related technology, and can be used in the field of engineering machinery technology.

[0046] Reference Figures 1-6 The seat assembly includes a seat 1 and an armrest box 2. The seat 1 is mounted on the vehicle body and used for passenger seating. The armrest box 2 is rotatably connected to the seat 1 along a first direction, wherein the first direction is... Figure 2 The armrest box 2 is positioned along the AB direction, and the center line of rotation of the armrest box 2 relative to the seat 1 extends along the left-right direction of the seat 1. A first connecting part connects the seat 1 and the armrest box 2, while a plurality of second connecting parts are provided on the second part of the seat 1 and the armrest box 2. These multiple second connecting parts are sequentially arranged along the first direction. The first connecting part can be detachably connected to one of the multiple second connecting parts. Thus, when the armrest box 2 rotates relative to the seat 1 along the first direction, the detachable connection between the first and second connecting parts fixes the position of the armrest box 2 relative to the seat 1, thereby locking their relative positions. When it is necessary to adjust the position of the armrest box 2 relative to the seat 1, the first connecting part can be removed from the second connecting part to release the locking of their relative positions. Furthermore, this seat assembly only requires connecting and removing the first and second connecting parts to achieve locking and unlocking of the position of the armrest box 2 relative to the seat 1, resulting in a simple structure and low cost.

[0047] Continue to refer to Figures 1-6The first connecting part is a connecting screw 31, and the second connecting part is a mounting hole 32. The first of the seat 1 and the armrest box 2 is provided with a threaded hole. The connecting screw 31 can pass through the mounting hole 32 and engage with the threaded hole. Thus, the connection and disassembly between the seat 1 and the armrest box 2 can be achieved through the engagement between the connecting screw 31 and the mounting hole 32.

[0048] This embodiment exemplifies a configuration where the seat 1 and the armrest box 2 are, respectively, the first connecting part is connected to the seat 1 and the second connecting part is disposed in the armrest box 2. In other embodiments, the first connecting part can be the armrest box 2 and the second connecting part can be the seat 1, with the first connecting part connected to the armrest box 2 and the second connecting part disposed in the seat 1.

[0049] Optionally, the armrest box 2 includes an armrest box body 21 and a mounting plate 22, with a mounting hole 32 provided on the mounting plate 22. To prevent the head of the connecting screw 31 from directly pressing against the mounting plate 22 and damaging it, a spacer 33 is provided between the head of the screw 31 and the mounting plate 22, and the connecting screw 31 passes through the spacer 33 and the mounting hole 32 in sequence.

[0050] Optionally, among the multiple mounting holes 32, at least two are interconnected, making the distance between the two mounting holes 32 close, facilitating small-angle adjustment of the armrest box 2 relative to the seat 1. In this embodiment, two mounting holes 32 are provided, and the two mounting holes 32 are interconnected, forming an overall figure-eight shape. Optionally, after the connecting screw 31 moves from one mounting hole 32 to another, the armrest box 2 rotates relative to the seat 1 by 10°. It is understood that this value can also be set according to actual conditions. For example, in some embodiments, when the connecting screw 31 moves from one mounting hole 32 to another, the angle of rotation of the armrest box 2 relative to the seat 1 is 5°, 15°, or 20°. In addition, in other embodiments, the number of mounting holes 32 can be set to more than two, such as three, four, or five. In some other embodiments, the multiple mounting holes 32 are each set independently, that is, there are no two mounting holes 32 that are connected to each other. This setting ensures that there is a certain distance between any two adjacent mounting holes 32, which makes it convenient for the operator to align a specific mounting hole 32 and facilitates operation.

[0051] As an alternative, the first connecting part and the second connecting part can also be connected by a plug-in method. Specifically, the first connecting part is a plug post, and the second connecting part is a socket, with the plug post capable of being selectively plugged into multiple sockets. Furthermore, the first connecting part and the second connecting part can also be connected by a snap-fit ​​or magnetic connection.

[0052] Continue to refer to Figures 1-6The seat 1 includes a seat base 4, a rotating base 5, and a seat body 6. The seat base 4 is used for fixed installation on the vehicle body; the rotating base 5 is rotatably connected to the seat base 4 along a second direction, wherein the second direction is... Figure 3 as well as Figure 6 The rotating base 5 is oriented in the CD direction, and its center line of rotation relative to the seat base 4 extends vertically. The seat body 6 is fixedly connected to the rotating base 5 and is used for occupancy. The armrest box 2 is connected to the seat body 6. This allows the rotating base 5 to rotate relative to the seat base 4, adjusting the angles of the rotating base 5 and the seat body 6 relative to the seat base 4 to meet the driver's needs and improve comfort. Furthermore, the armrest box 2 is connected to the seat body 6, allowing it to move synchronously with the seat body 6. Compared to directly connecting the armrest box 2 to the vehicle body, this allows for adjustment of the armrest box 2's position simultaneously with the adjustment of the seat body 6's position.

[0053] Continue to refer to Figures 1-6 The first of the seat base 4 and the rotating base 5 is provided with a third connecting part, and the second of the seat base 4 and the rotating base 5 is provided with a plurality of fourth connecting parts. The plurality of fourth connecting parts are spaced apart along the second direction. The third connecting part can be detachably connected to one of the plurality of fourth connecting parts. Thus, when the rotating base 5 rotates relative to the seat base 4 along the second direction, the position of the rotating base 5 relative to the seat base 4 can be fixed through the detachable connection between the third connecting part and the fourth connecting part, thereby locking the relative position of the two. When it is necessary to adjust the position of the rotating base 5 relative to the seat base 4, the third connecting part can be removed from the fourth connecting part to release the relative position lock.

[0054] In this embodiment, an exemplary configuration is provided in which the first of the seat base 4 and the rotating base 5 is the rotating base 5 and the second is the seat base 4, that is, the third connecting part is disposed on the rotating base 5 and the fourth connecting part is disposed on the seat base 4. In other embodiments, the first of the seat base 4 and the rotating base 5 may be the seat base 4 and the second is the rotating base 5, that is, the third connecting part is disposed on the seat base 4 and the fourth connecting part is disposed on the rotating base 5.

[0055] Continue to refer to Figures 1-6The third connecting part is a plug 71, and the fourth connecting part is a slot 72. The plug 71 can move relative to one of the seat base 4 and the rotating base 5. Specifically, the plug 71 can rotate relative to one of the seat base 4 and the rotating base 5, and has a fixed position and a movable position. When the plug 71 is in the fixed position, the plug 71 can be inserted into the slot 72 and prevent the rotating base 5 from rotating relative to the seat base 4. When the plug 71 is in the movable position, the plug 71 is dislodged from the slot 72, and the rotating base 5 can rotate relative to the seat base 4. Therefore, when it is necessary to adjust the relative position between the seat base 4 and the rotating base 5, the plug 71 can be adjusted to the movable position, that is, the plug 71 is controlled to dislodge from the slot 72 so that the rotating base 5 can rotate relative to the seat base 4. After the adjustment of the relative position between the seat base 4 and the rotating base 5 is completed, the plug 71 can be adjusted to the fixed position, that is, the plug 71 is controlled to be inserted into the slot 72 to prevent the rotating base 5 from rotating relative to the seat base 4.

[0056] Optionally, there are two slots 72, which correspond to the two extreme positions of the rotating base 5 relative to the seat base 4. When the insert block 71 moves from one slot 72 to the other slot 72, the rotating base 5 rotates at an angle of 15° relative to the seat base 4. In other embodiments, this value can be set according to the actual situation.

[0057] Continue to refer to Figures 1-6 The insert 71 is connected to an elastic element 74, which provides an elastic force to move the insert 71 toward a fixed position. This allows the insert 71 to move toward a fixed position under the action of the elastic element 74 when it is not subjected to external force, thereby preventing the rotating base 5 from rotating relative to the seat base 4 and locking their relative positions.

[0058] Continue to refer to Figures 1-6 The plug 71 is fixedly connected to a handle 73. The handle 73 can move the plug 71 relative to the first of the seat base 4 and the rotating base 5. Thus, when it is necessary to adjust the relative position between the seat base 4 and the rotating base 5, the user can control the plug 71 by manipulating the handle 73, which is convenient for operation.

[0059] Continue to refer to Figures 1-6 The seat base 4 includes a fixing member 41 and a mounting seat 42. The fixing member 41 is used to fix the seat to the vehicle body. The rotating base 5 is connected to the mounting seat 42. The mounting seat 42 is slidably disposed on the fixing member 41, so that the seat body 6 can not only rotate relative to the vehicle body, but also slide relative to the vehicle body through the sliding cooperation between the mounting seat 42 and the fixing member 41, further improving the flexibility of the position adjustment of the seat body 6.

[0060] This embodiment also provides engineering machinery, including the aforementioned seat assembly and a vehicle body. The seat 1 of the seat assembly is mounted on the vehicle body. In this seat assembly, when the armrest box 2 rotates relative to the seat 1 along a first direction, the position of the armrest box 2 relative to the seat 1 can be fixed through a detachable connection between the first connecting part and the second connecting part, thereby locking the relative positions of the two. When it is necessary to adjust the position of the armrest box 2 relative to the seat 1, the first connecting part can be removed from the second connecting part to release the locking of the relative positions. Furthermore, this seat assembly only requires the connection and removal of the first connecting part and the second connecting part to achieve the locking and unlocking of the position of the armrest box 2 relative to the seat 1, which is simple in structure and low in cost.

[0061] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
