Description

Technical Field

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

[0002] In the field of modern excavating machinery technology, ergonomics and mechanical design have been widely applied. Excavators are large construction machines typically used for digging, loading, and transporting earth, rock, or other materials. Operating excavators requires a high degree of precision and comfort; therefore, the design of the excavator cab and the comfort of the driver's seat have become important research directions.

[0003] Existing excavator seats are mainly manually adjustable, which is not convenient, and the seats are not equipped with foot pedals. As a result, when the driver does not need to control the accelerator, brake and other functional pedals, there is nowhere to put his feet, which reduces the driver's comfort when resting. Utility Model Content

[0004] In order to overcome at least one of the defects of the prior art, the present invention provides an excavator seat that can solve the problems of excavator seats requiring manual adjustment and the lack of foot pedals leaving the driver with nowhere to place his feet.

[0005] The technical solution adopted by this utility model to solve its problem is:

[0006] An excavator seat, mounted on an excavator, includes:

[0007] Backrest;

[0008] A seat cushion, wherein the backrest is rotatably connected to the seat cushion, and a first driving component is provided at the rotatable connection between the backrest and the seat cushion, the first driving component being used to drive the backrest to rotate relative to the seat cushion;

[0009] A foot pedal assembly, comprising a foot pedal and a second drive assembly, wherein one end of the second drive assembly is connected to the seat cushion and the other end is connected to the foot pedal, such that the second drive assembly drives the foot pedal to extend outward toward the side away from the seat cushion or drives the foot pedal to retract toward the side of the seat cushion.

[0010] A controller, which is electrically connected to the first drive component and the second drive component respectively.

[0011] By adopting the above solution, the backrest and seat cushion are adjustable via the first drive assembly, allowing the driver to adjust the seat angle according to their needs, thereby improving driving comfort. The footrest assembly can extend or retract, making it easier for the driver to find the most suitable footrest position, which is especially important for drivers working long hours, helping to reduce fatigue and improve work efficiency. The controller adjusts the backrest's tilt angle relative to the seat cushion and the footrest position, thus avoiding the inconvenience of manual adjustment.

[0012] Furthermore, it also includes a lifting assembly, which is located at the bottom of the seat cushion to drive the seat cushion to move up and down reciprocally. The lifting assembly is electrically connected to the controller.

[0013] By adopting the above solution, the lifting function of the lifting component allows the driver to adjust the seat height according to their own height or preference, ensuring the best visibility and the most comfortable body position when operating the excavator.

[0014] Furthermore, the excavator is equipped with a display screen, and the controller is integrated into the display screen.

[0015] By adopting the above solution, the controller is integrated into the display screen, reducing the need for additional physical buttons or control panels. This makes the operating interface simpler, easier to understand and use. Drivers can directly adjust various seat settings, such as backrest angle, foot pedal position, and seat height, through the touch screen without leaving the seat or searching for specific control devices, thus making the settings adjustment faster.

[0016] Furthermore, the second drive component is a telescopic rod, which is electrically connected to the controller. One end of the telescopic rod is connected to the seat cushion, and the other end is connected to the foot pedal, so as to drive the foot pedal to extend outward toward the side away from the seat cushion or to drive the foot pedal to retract toward the side of the seat cushion.

[0017] By adopting the above solution, the telescopic rod design allows the foot pedal to extend and retract freely within a certain range. The driver can adjust the position of the foot pedal according to personal needs and comfort to achieve the best operating state. Furthermore, the telescopic rod can be infinitely adjusted to further improve comfort.

[0018] Furthermore, the second drive assembly includes a driver and an adapter rod, one end of which is rotatably connected to the seat cushion and the other end of which is connected to the foot pedal. The driver is connected to the adapter rod to drive the adapter rod to rotate about the rotatable connection point between the adapter rod and the seat cushion as an axis. The driver is electrically connected to the controller.

[0019] By adopting the above solution, the foot pedal, through the rotating connection design between the adapter rod and the seat cushion, can rotate along the rotating connection point between the adapter rod and the seat cushion. This allows it to fit snugly under the seat cushion when not in use, effectively utilizing limited space and significantly reducing the risk of tripping when getting in and out of the vehicle, thus improving safety. Furthermore, this design allows the foot pedal to be completely retracted under the seat cushion when not in use without interfering with the seat cushion lifting assembly's settings and lifting operation, simplifying the design and installation of the lifting assembly.

[0020] Furthermore, the foot pedal is rotatably connected to the adapter rod.

[0021] By adopting the above solution, the rotatable connection between the foot pedal and the adapter rod allows the foot pedal to rotate around the connection point between the foot pedal and the adapter rod. The driver can not only adjust the fore-and-aft position of the foot pedal, but also adjust its tilt angle to adapt to different leg support needs.

[0022] Furthermore, the adapter rod is rotatably connected to the side of the seat cushion away from the backrest.

[0023] By adopting the above solution, the adapter rod is rotatably connected to the side of the seat cushion away from the backrest, which can effectively reduce the space occupied by the foot pedal assembly under the seat cushion. Since the space occupied by the foot pedal assembly is reduced, the design and installation of the lifting assembly becomes easier, and a more efficient mechanical structure can be used to realize the lifting function of the seat without worrying about interference with the foot pedal assembly.

[0024] Furthermore, a headrest is provided at the end of the backrest away from the seat cushion.

[0025] By adopting the above solution, the headrest can provide additional head support, enabling the driver to maintain a comfortable posture during long-distance driving, reducing neck pressure and fatigue. In the event of a collision, the headrest can act as a buffer, reducing the risk of head and neck injuries and improving driving safety.

[0026] In summary, the excavator seat provided by this utility model has the following technical effects:

[0027] 1. Because the backrest and seat cushion are adjustable via the first drive assembly, the driver can adjust the seat angle according to their needs, thereby improving driving comfort. The footrest assembly can extend or retract via the second drive assembly, allowing the driver to more easily find the most suitable footrest position. This is especially important for drivers who work long hours, helping to reduce fatigue and improve work efficiency.

[0028] 2. The backrest tilt angle relative to the seat cushion and the position of the footrest are adjusted via a controller, thus avoiding the inconvenience of manual adjustment. Attached Figure Description

One end of the second drive assembly 42 is connected to the seat cushion 2, and the other end is connected to the foot pedal 41, so that the second drive assembly 42 drives the foot pedal 41 to extend outward toward the side away from the seat cushion 2 or drives the foot pedal 41 to retract toward the side of the seat cushion 2. The controller 5 is electrically connected to the first drive assembly 3 and the second drive assembly 42 respectively.

[0038] Specifically, the backrest 1 and the seat cushion 2 are rotatably connected. A first drive assembly 3 is provided at the rotatable connection between the backrest 1 and the seat cushion 2. The first drive assembly 3 is used to drive the backrest 1 to rotate relative to the seat cushion 2. The first drive assembly 3 is a conventional drive assembly that can adjust the tilt angle of the backrest 1 relative to the seat cushion 2 by inputting a drive signal through the controller 5. For example, the structure for driving the backrest 1 to rotate relative to the seat cushion 2 disclosed in CN219406229U is shown. Since the focus of this utility model is not on the first drive assembly 3, only one possible implementation method of the first drive assembly 3 will be exemplified, and other possible implementation methods of the first drive assembly 3 will not be described in detail. The foot pedal assembly includes a foot pedal 41 and a second drive assembly 42. One end of the second drive assembly 42 is connected to the seat cushion 2, and the other end is connected to the foot pedal 41. The second drive assembly 42 drives the foot pedal 41 to extend outward toward the side away from the seat cushion 2 or retracts the foot pedal 41 toward the side of the seat cushion 2, so that the driver can choose whether the foot pedal 41 extends and the extension distance according to needs. The second drive assembly 42 can be a telescopic rod or linkage, capable of driving the foot pedal 41 to extend and retract relative to the seat 2. The controller 5 is electrically connected to the first drive assembly 3 and the second drive assembly 42, respectively, to electrically control the operation of the first drive assembly 3 and the second drive assembly 42. The controller 5 can be a button-type controller, allowing control of the first drive assembly 3 or the second drive assembly 42 by pressing corresponding buttons. Alternatively, the controller 5 can be integrated into the excavator's display screen 7, allowing operation via touchscreen on the display screen 7.

[0039] See Figure 1 and Figure 3 As shown, in some embodiments, the excavator seat also includes a lifting assembly 6, which is located at the bottom of the seat cushion 2 to drive the seat cushion 2 to move up and down in a reciprocating motion. The lifting assembly 6 is electrically connected to the controller 5.

[0040] Specifically, the lifting component 6 is located at the bottom of the seat cushion 2 and is used to drive the seat cushion 2 to rise or fall. The lifting component 6 is electrically connected to the controller 5 so that the movement of the lifting component 6 can be controlled by the controller 5. The lifting component 6 can adopt a conventional worm gear motor and rack and pinion combination, or it can use a cylinder, hydraulic cylinder or other telescopic component to drive the seat cushion 2 to rise and fall.

[0041] See Figure 1 and Figure 3 As shown, in some embodiments, in order to simplify the internal structure of the excavator, the excavator is equipped with a display screen 7, and the controller 5 is integrated into the display screen 7. That is, the first drive component 3, the second drive component 42 or the lifting component 6 can be controlled by clicking the display screen 7 or the button connected to the display screen 7.

[0042] In some embodiments, the second drive assembly 42 is a telescopic rod, which is electrically connected to the controller 5. One end of the telescopic rod is connected to the seat cushion 2, and the other end is connected to the foot pedal 41, so as to drive the foot pedal 41 to extend outward toward the side away from the seat cushion 2 or to drive the foot pedal 41 to retract toward the side of the seat cushion 2.

[0043] The above-mentioned telescopic rod controls the foot pedal 41 to move freely within a certain range. The driver can adjust the position of the foot pedal 41 according to personal needs and comfort to achieve the best operating state. Furthermore, the telescopic rod can be infinitely adjusted to further improve comfort.

[0044] See Figure 1-Figure 3 As shown, in some other embodiments, the second drive assembly 42 includes a driver 421 and a connecting rod 422.
