DETAILED DESCRIPTION

[0019] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0020] The term "and / or" in this article is only a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship. Embodiment 1

[0021] This embodiment provides a control system, such as Figure 1 As shown, it includes a support assembly 11, a rotation and sliding assembly 12, a seat 13 and an armrest box assembly 14. Figure 2 In this embodiment, the bottom of the operating system is a support assembly 11 which serves as a bottom support and a protective function. The support assembly 11 is provided with two sets of parallel guide grooves, which are respectively arranged at the front and rear sides of the support assembly 11. The guide grooves extend from the door on one side of the cab to the door on the other side, so as to realize the sliding guidance of the seat 13 between the two doors.

[0022] Furthermore, a rotating sliding assembly 12 is installed above the support assembly 11, and the rotating sliding assembly 12 includes a sliding mechanism 121 and a rotating mechanism 122. Among them, the front and rear sides of the sliding mechanism 121 are respectively provided with a slide rail and a slider that can slide left and right on the slide rail, and the left and right sides of the slide rail are provided with a raised limiting structure; when the slider moves to the limit position, the limiting structure can prevent it from continuing to move, playing a role in limiting the travel limit of the sliding rail. A slide groove is provided between the slide rail and the slider of the sliding mechanism 121, and the slide groove is clamped in the guide groove, so that the slider can move according to the guidance of the guide groove, thereby realizing the sliding connection between the sliding mechanism 121 and the support assembly 11.

[0023] A rotating mechanism 122 is relatively rotatably arranged above the sliding mechanism 121, and its function is to make the components connected to the rotating mechanism 122 rotate 90° to the left or right relative to the sliding mechanism 121, and the components connected to the rotating mechanism 122 include a seat 13 installed above the rotating mechanism 122 and an armrest box assembly 14 arranged beside the seat 13. The armrest box assembly 14 includes an armrest box 141 and a control mechanism arranged on the armrest box 141; for the engineering machinery equipped with the operating system 1 provided in this embodiment, the control mechanism can not only control the engineering machinery to perform simple actions such as forward and backward, but also at least control the engineering machinery to perform steering and / or engineering operations.

[0024] It should be noted that the rotating and sliding assembly 12 can be electrically connected to the control mechanism, and the sliding and rotating functions can be realized by operating the control mechanism; however, as an equivalent variation, the rotating and sliding assembly 12 can also be not controlled by the control mechanism, but can be realized by manual operation. The sliding mechanism 121 and the rotating mechanism 122 can be driven by a gear rack, or by other driving methods such as a telescopic cylinder. In practical applications, appropriate connection and driving methods can be set according to actual conditions, as long as the sliding and rotating functions can be realized and the same effect can be achieved.

[0025] This embodiment integrates the control mechanism on the armrest boxes on both sides, eliminates the traditional pillars, central control components and large-sized steering wheels, makes the front of the seat unobstructed, ensures the driver's leg space, and provides sufficient operating space for the driver to rotate or slide, which is convenient for the driver to work. In addition, the sliding mechanism is slidably connected to the support assembly, and the seat is connected to the sliding mechanism through the rotating mechanism, so that the sliding mechanism can drive the seat to slide between the doors on both sides of the cab, and the rotating mechanism can drive the seat to rotate; therefore, the setting of the rotating sliding assembly expands the driver's operating field of view and meets the needs of refined operations.

[0026] As an optional embodiment, Figure 2 As shown, the armrest box assembly 14 can be provided with two groups, and the two groups of armrest box assemblies 14 can be respectively located on the left and right sides of the seat 13, so as to facilitate the driver's operation. It should be noted that the left and right sides here refer to the left and right sides when the driver sits on the seat 13. In this embodiment, the armrest box assembly 14 also includes an armrest box bracket 143, and the armrest box 141 is connected to the rotating mechanism 122 through the armrest box bracket 143. Specifically, the armrest box 141 can be provided with a left armrest box and a right armrest box, and the armrest box bracket 143 can be provided with a left bracket and a right bracket; one end of the left bracket is connected to the left armrest box, and the other end is connected to the left side of the rotating mechanism 122, so that the left armrest box is installed on the left side of the seat 13; one end of the right bracket is connected to the right armrest box, and the other end is connected to the right side of the rotating mechanism 122, so that the right armrest box is installed on the right side of the seat 13.

[0027] In this embodiment, if Figure 2 As shown, the control mechanism at least includes an operating handle 1421 and a steering wheel assembly 1422 respectively arranged on different armrest boxes 141. Specifically, the operating handle 1421 is arranged on the right armrest box, and is used to control the engineering machine to perform basic actions such as forward and backward; the steering wheel assembly 1422 is arranged on the left armrest box, and is used to control the engineering machine to perform steering and / or engineering operation actions. Figure 3The steering wheel assembly 1422 needs to be designed so as not to interfere with the front space of the seat 13, and includes a hand wheel 1422B and a handle ball 1422A mounted on the circumference of the hand wheel 1422B through an axis. The driver can manipulate the handle ball 1422A to make the engineering machine perform steering actions; when completing fine operations such as edging, the driver can rotate the hand wheel 1422B for fine adjustments to control the engineering machine to perform engineering operations and meet various construction requirements.

[0028] It should be noted that the positions of various control mechanisms such as the operating handle 1421 and the steering wheel assembly 1422 are not limited thereto, and can be set to appropriate positions according to the driver's operating habits to improve the driver's comfort and convenience during operation. In addition, the control mechanism includes not only the operating handle 1421 and the steering wheel assembly 1422, but also other control components such as function buttons and display screens.

[0029] In the control system provided in this embodiment, the steering wheel assembly is arranged on the armrest box, and a smaller hand wheel is used instead of a large diameter steering wheel, which will not interfere with the driver's front space and can meet the operational requirements of fine operations such as edging. Embodiment 2

[0030] The present embodiment provides a control system, which is different from the first embodiment in that the present embodiment is optimized on the basis of the first embodiment. For example, the steering wheel assembly 1422 also includes an adjustable steering column (not shown in the figure) that is transmission-connected to the hand wheel 1422B, and is used to adjust the inclination angle of the hand wheel to adapt to drivers with different operating habits. The adjustable steering column can be an up-down, front-back adjustable steering column in the prior art, which mainly includes an outer sleeve, a column body slidably mounted in the outer sleeve, and a chassis connected to the lower end of the outer sleeve through a hinge plate. The steering column can not only adjust the height, but also adjust the front and back inclination angle to adapt to drivers of different heights and body shapes and different operating habits. It has a simple structure and is easy to use. Other adjustable steering columns that can realize the function of adjusting the inclination angle can also be selected. Reference Figure 4 The steering wheel assembly 1422 is equipped with an adjustable steering column, which can be rotated 5° outward by applying pressure to adapt to the operating habits of different drivers.

[0031] As an example, refer to Figure 2, a front-to-back adjustment mechanism 131 for adjusting the front-to-back position of the seat 13 is provided below the seat 13. The seat 13 is connected to the rotating mechanism 122 through the front-to-back adjustment mechanism 131, so that the seat 13 can move forward and backward to adapt to drivers of different heights and body shapes. The front-to-back adjustment mechanism 131 can adopt the existing technology. The front-to-back adjustment mechanism 131 can include a first slide rail, a second slide rail slidably connected to the first slide rail, and a front-to-back adjustment handle for adjusting the relative position of the first slide rail and the second slide rail; the first slide rail can be set on the rotating mechanism 122, and the second slide rail can be connected to the seat 13. The driver can adjust the relative position of the first slide rail and the second slide rail by pulling the front-to-back adjustment handle, thereby adjusting the front-to-back position of the seat 13, so that the seat 13 can adapt to drivers of different heights and body shapes, which is conducive to improving the comfort of the driver. Other front-to-back adjustment mechanisms 131 that can adjust the front-to-back position of the seat 13 can also be selected.

[0032] In some embodiments, reference Figure 2 The operating system 1 may further include a brush 15 disposed on the guide groove of the support assembly 11. The brush 15 can effectively prevent foreign matter from entering the guide groove of the support assembly 11, thereby ensuring that the sliding mechanism 121 can move smoothly left and right.

[0033] This embodiment configures an adjustable steering column on the steering wheel assembly to adjust the inclination angle and configures a front and rear adjustment mechanism on the seat to adjust the front and rear position of the seat, so that the operating system can adapt to drivers of different heights and body shapes and different operating habits, which helps to improve the driver's comfort and convenience during operation; by configuring a brush on the support assembly, it can effectively prevent foreign matter from entering the rotating sliding assembly, thereby improving operating efficiency. Embodiment 3

[0034] This embodiment provides a cab, such as Figure 6 As shown, it includes a base 2 and a manipulation system 1 as provided in the first embodiment and / or the second embodiment. Figure 1 The support assembly 11 of the operating system 1 is installed on the base 2, and the sliding mechanism 121 is arranged in the base 2 through the support assembly 11.

[0035] This embodiment configures the operating system 1 on the base 2, which not only reduces the occupied space in the cab, making the layout of the cab more reasonable, neat and beautiful; but also eliminates the traditional support column and central control components, providing sufficient operating space for the driver's rotation or sliding action. Figure 5 (a), the driver can turn 90° to the left; combined Figure 5 (b), the driver can rotate right 90°; the rotating mechanism 122 can provide the driver with an operational space and field of view of 180°. Figure 5 (c), the driver can slide to the right side of the cab; combined with Figure 5 (d), the driver can slide to the left side of the cab; the sliding mechanism 121 can facilitate the driver to slide to both sides of the cab door to observe the working conditions, ensure a good edge view, and meet the needs of edge work. In the cab, the rotating sliding assembly 12 can rotate or slide the seat 13 to different angles and positions in the cab, which can provide the driver with various operating directions and all-round vision, facilitate the driver to perform various operations, and meet the construction requirements under different working conditions.
