[0050] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without carrying out creative work are within the scope of protection of this application.

[0051] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0052] In the description of this application, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of this application; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0053] In the description of this application, it should be understood that the use of words such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above words have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0054] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0055] Figures 1-14 The structure of the control box of the present application is shown as an example.

[0056] See also Figures 1-14 In the present application, the control box 10 includes a main box 1 and an auxiliary box 2. The main box 1 includes a first box body 11 and a handle 12, and the handle 12 is arranged on the first box body 11. The auxiliary box 2 includes a second box body 21 and an electrical device 22, and the electrical device 22 is arranged on the second box body 21. The second box body 21 is connected to one side of the first box body 11 along the left and right direction or the front and back direction of the engineering machinery, and is supported by the first box body 11. It can be understood that the front and back and left and right directions of the engineering machinery are defined based on the normal driving state of the engineering machinery, wherein the forward direction of the engineering machinery is the front, the backward direction is the rear, and the left and right when facing the front are respectively left and right. The front and back direction of the engineering machinery corresponds to the length direction of the main box 1. The left and right direction of the engineering machinery corresponds to the width direction of the main box 1.

[0057] In the above scheme, the auxiliary box 2 is no longer independent of the main box 1, but is connected to one side of the main box 1 along the left and right direction or the front and rear direction of the engineering machinery and is supported by the main box 1. In this way, there is no need to equip the auxiliary box 2 with a special support structure. Therefore, it can effectively reduce space occupancy, improve the space utilization of the cab, and save costs.

[0058] Moreover, since the main box 1 is usually close to the operator's main hand area, the connection of the auxiliary box 2 to the main box 1 is also conducive to reducing the distance between the auxiliary box 2 and the operator's main hand area, improving the convenience and comfort of operation, reducing the risk of operator fatigue, and improving work efficiency.

[0059] It can be seen that by connecting the auxiliary box 2 to the main box 1 linked to the seat, the space occupied by the control box 10 can be effectively reduced and the operation convenience of the control box 10 can be improved.

[0060] In order to further improve the operation convenience of the control box 10, see Figure 1-Figure 3 In some embodiments, the control box 10 includes not only the main box 1 and the auxiliary box 2, but also a connector 31. The connector 31 connects the first box 11 and the seat of the engineering machine, so that the main box 1 can move along the front and rear direction of the engineering machine with the seat.

[0061] Because the main box 1 is connected to the seat of the engineering machine via the connector 31, the main box 1 can be linked to the seat. Thus, when drivers of different sizes move the seat forward and backward, the main box 1 can move forward and backward along with the seat, allowing the main box 1 to adapt to the operating needs of drivers of different sizes, improving operating convenience and comfort, reducing the risk of operator fatigue, and improving work efficiency. Furthermore, because the auxiliary box 2 is connected to the main box 1, the auxiliary box 2 can move forward and backward along with the seat, adapting to the operating needs of drivers of different sizes, improving operating convenience and comfort, reducing the risk of operator fatigue, and improving work efficiency.

[0062] It can be seen that by providing the connecting piece 31 to connect the main box 1 connected to the auxiliary box 2 to the seat, the operating convenience and comfort of the control box 10 can be further improved.

[0063] Further, see Figure 1-Figure 3 In some embodiments, the control box 10 includes not only a connector 31 but also a linkage mechanism 32. The linkage mechanism 32 connects the connector 31 and the first box 11, enabling the first box 11 to move forward and backward and / or up and down relative to the seat. In this way, the main box 1 and the auxiliary box 2 connected to the main box 1 can not only move forward and backward with the seat, but also move forward and backward and / or up and down relative to the seat. This allows for more flexible operation to meet different operating requirements, further improving ease of operation and comfort.

[0064] In the above embodiments, the connection between the auxiliary box 2 and the main box 1 can be various. Figure 2-Figure 9In some embodiments, the second box 21 is mounted on the first box 11. This facilitates assembly, provides reliable connection, and facilitates detachable connection between the main box 1 and the auxiliary box 2, allowing the main box 1 and the auxiliary box 2 to be used in combination or separately, flexibly meeting different usage requirements.

[0065] In order to realize the connection of auxiliary box 2 on main box 1, see Figure 2-Figure 9 In some embodiments, the second housing 21 is provided with an inserting plate 5, and the first housing 11 is provided with a slot 19. The inserting plate 5 protrudes outward from the second housing 21 and is inserted into the slot 19. The inserting plate 5 is connected to the first housing 11 via the fastening device 8, thereby achieving the connection between the second housing 21 and the first housing 11. In this case, the structure is simple and the assembly is convenient.

[0066] Specifically, see Figure 4-Figure 8 In some embodiments, the plugboard 5 includes a first plate body 51 and a second plate body 52, the fastening device 8 includes a first fastener 81 and a second fastener 82, the first plate body 51 is inserted into the slot 19, the second plate body 52 extends downward from the first plate body 51 and is located in the first box body 11, a first hole 53 is provided on the first plate body 51, and a second hole 54 is provided on the second plate body 52, the first fastener 81 passes through the first hole 53 to connect the first plate body 51 and the first box body 11, and the second fastener 82 passes through the second hole 54 to connect the second plate body 52 and the first box body 11.

[0067] Based on the above setting, the auxiliary box 2 and the main box 1 are connected in a suspended manner. The auxiliary box 2 is suspended in the air and no supporting structure is required underneath. Therefore, the space occupied can be effectively reduced and space can be saved. Moreover, a tight and stable force lever can be formed between the auxiliary box 2 and the main box 1, thereby realizing the stable setting of the auxiliary box 2 on one side of the main box 1.

[0068] Figure 9 The force diagram of the above arrangement is shown in FIG. Figure 9 In the above scheme, the auxiliary box 2 is suspended on one side of the main box 1. Affected by the weight of the auxiliary box 2 itself, the auxiliary box 2 will have a tendency to rotate with the first fastener 81 as the fulcrum and the lower end of the plug plate 5 as the movement limit. In this case, on the basis of setting the first fastener 81 for limiting fixation, a second fastener 82 connected to the second plate 52 is further set to inhibit rotation, which can form a stable lever force form, prevent the auxiliary box 2 from tipping over, and improve the stability of the auxiliary box 2 on one side of the main box 1.

[0069] Further, see Figure 5In some embodiments, a notch 55 is provided on the sidewall of the second hole 54. In this case, the second hole 54 is a non-enclosed hole. This not only limits the second fastener 82 to inhibit rotation, but also facilitates the second fastener 82 to connect the second plate 52 and the first box 11. This is particularly convenient for connecting the second plate 52 and the first box 11 using the second fastener 82 within a relatively narrow first box 11, which helps reduce assembly difficulty and improve assembly efficiency.

[0070] The shape of the second hole 54 can be varied, for example, see Figure 5 In some embodiments, the second hole 54 is U-shaped. In addition, the notch 55 can be located at any position of the side wall of the second hole 54, for example, the notch 55 can be located at the lower end, upper end, left end and right end of the side wall of the second hole 54.

[0071] As a further improvement to the above embodiments, see Figure 6 In some embodiments, the top cover 16 of the second housing 21 includes a first cover 43 and a second cover 44. The first cover 43 is connected to the front end of the second cover 44. The first cover 43 is provided with the electrical device 22 and is gradually tilted upward from back to front. For example, in some embodiments, the upward tilt angle of the first cover 43 is greater than or equal to 3° and less than 90°. This facilitates the user's hand to press and operate the electrical device 22 on the first cover 43, meets the need for visual observation, provides a better comfort experience, and helps further improve the comfort and convenience of operation.

[0072] As mentioned above, the control box in the related art has the problems of inconvenience in operation and taking up a lot of space. In fact, the control box in the related art also has the problems of being difficult to be compatible with the installation requirements of handles of different specifications, and having poor versatility and scalability.

[0073] Specifically, various types of construction machinery are becoming more and more diversified in configuration, and the matching handles they need to be equipped with are also becoming more and more diverse. The specifications of these handles are not the same. For example, electric control handles, thumb handles and hydraulic control handles all have different operating methods, height dimensions and working angles. However, in related technologies, when designing an operation box, a matching design is often made for a certain type of handle. That is to say, the same main box can usually only install a handle of a certain specification, but cannot install handles of other specifications. Replacing another handle often requires a completely new matching design, which is especially difficult to meet the installation requirements of handles of different heights and sizes. The versatility and subsequent scalability are poor, which can easily lead to unnecessary waste and increase production costs.

[0074] In order to solve the problem that the control box in the above related technologies is difficult to be compatible with the installation requirements of handles of different specifications, and has poor versatility and scalability, see Figure 10-12In some embodiments, a supporting device 7 is provided in the first box body 11 , and the height of the supporting device 7 is adjustable to support handles 12 of different heights.

[0075] Since the support device 7 in the main box 1 can change the height and support the handles 12 with different heights, the main box 1 can meet the installation requirements of handles 12 with different heights, so that the same main box 1 can meet a variety of configuration needs. In this way, the versatility and subsequent expandability of the control box 10 can be effectively improved, repeated design can be reduced, and design and production costs can be reduced.

[0076] Moreover, by changing the height of the support device 7, it is also beneficial to ensure that different handles 12 are all within a more comfortable height range, which is also beneficial to flexibly meet the manipulation needs of people of different body shapes and improve manipulation comfort.

[0077] There are many ways to achieve height adjustment of the support device 7 .

[0078] As one way, see Figure 10-12 In some embodiments, the support device 7 includes a first bracket 71, which is disposed in the first box 11. The first bracket 71 is provided with a connecting portion 73, which is used to connect to a second bracket 72 of different heights to make the support device 7 height adjustable. In this case, the height of the support device 7 can be changed by connecting or not connecting the second bracket 72, or by replacing the second bracket 72 of different heights, thereby meeting the installation requirements of handles 12 of different heights. For example, see Figures 9-12 In some embodiments, a first bracket 71 is set based on the height of the support device 7 corresponding to any one of all the handles 12 that may need to be installed, and then the installation requirements of other handles 12 are met by switchably connecting second brackets 72 of different heights to the first bracket 71 (for example, the upper side and / or the lower side). That is, the height of the first bracket 71 is made equal to the height of the support device 7 corresponding to any one of all the handles 12 that need to be installed, and then the other handles 12 are adapted by replacing the second brackets 72 of different heights.

[0079] As another way, the support device 7 includes a first bracket 71, and the first bracket 71 is movably arranged relative to the first box body 11, so that the height of the support device 7 is adjustable. At this time, the height of the support device 7 can be changed by moving the first bracket 71, thereby meeting the installation requirements of handles 12 of different height sizes. The movement of the first bracket 71 can be at least one of sliding up and down, telescoping and rotating. For example, the first bracket 71 can be slidable up and down, telescopic or rotatable in the first box body 11, so that the height of the support device 7 is adjustable. It can be understood that the sliding of the first bracket 71 up and down means that the first bracket 71 as a whole slides up and down relative to the first box body 11; and the telescopic nature of the first bracket 71 means that the first bracket 71 includes at least two sections that can slide up and down relative to each other.

[0080] The above-mentioned method of movable setting of the first bracket 71 and the method of replacing different second brackets 72 can be used selectively or in combination. For example, when the first bracket 71 is provided with the aforementioned connecting portion 73 for connecting to the second brackets 72 of different heights, the first bracket 71 can be movable or immovable. Among them, when the first bracket 71 is movable, the installation requirements of handles 12 of different specifications can be met by moving the first bracket 71, or by replacing different second brackets 72. The method of adapting to handles 12 of different specifications is more flexible and can adapt to the installation requirements of handles 12 within a larger height range, which is conducive to further improving the versatility and later expandability of the control box 10.

[0081] In addition, in order to solve the problem that the control box in the above related technology is difficult to be compatible with the installation requirements of handles of different specifications, and has poor versatility and scalability, see Figure 3 In some embodiments, the top cover 16 of the first housing 11 is provided with an exterior panel 13, which has through-holes 1b for different handles 12 to pass through. This allows the main box 1 to accommodate handles of varying widths, further enhancing the versatility and future expandability of the control box 10. Alternatively, the exterior panel 13 with through-holes 1b of varying sizes can be replaced to accommodate handles of varying widths.

[0082] In the aforementioned embodiments, the auxiliary box 2 can be connected to one side of the main box 1 in the front-to-back direction or one side in the left-to-right direction. However, compared with the case where the auxiliary box 2 is connected to one side of the main box 1 in the front-to-back direction, it is more convenient to operate when the auxiliary box 2 is connected to one side of the main box 1 in the left-to-right direction.

[0083] In addition, in the above embodiments, the number of the auxiliary boxes 2 in the control box 10 can be one, two or more. Figure 13 and Figure 14When the control box 10 includes at least two auxiliary boxes 2, the at least two auxiliary boxes 2 can be located on the same side or on opposite sides of the main box 1. Moreover, when the at least two auxiliary boxes 2 are located on the same side of the main box 1, the at least two auxiliary boxes 2 can be connected side by side in the left-right direction to further facilitate control.

[0084] Next, combine Figures 1-14 The illustrated embodiments further illustrate the present application.

[0085] First, let’s introduce Figures 1-12 The first embodiment is shown.

[0086] like Figures 1-12 As shown, in this embodiment, the control box 10 includes a main box 1, a connecting member 31, a linkage mechanism 32 and a sub-box 2.

[0087] The main box 1 is used to install the handle 12. Figure 1-Figure 3 As shown, in this embodiment, the main box 1 includes a first box body 11, a handle 12 and an elbow rest 14. The first box body 11 includes a top cover 16, a shell 17 and a frame 18. The top cover 16 of the first box body 11 is set on the top of the shell 17. The frame 18 of the first box body 11 is set in the chamber enclosed by the top cover 16 and the shell 17. The handle 12 and the elbow rest 14 are both set on the top cover 16 of the first box body 11. Figure 2 and Figure 3 As shown, the handle 12 is located on the front portion of the top cover 16 of the first box body 11 , and the elbow rest 14 is located on the rear portion of the top cover 16 of the first box body 11 .

[0088] Specifically, if Figure 3 As shown, a storage space 1a for storing items is provided below the elbow rest 14 to meet the user's storage needs. Moreover, the elbow rest 14 is connected to the top cover 16 of the first box body 11 through a hinge 15, so that the elbow rest 14 can be rotated to open or close, opening or covering the storage space 1a below.

[0089] In order to realize the installation of the handle 12, as Figure 3 As shown, in this embodiment, an exterior panel 13 is provided on the top cover 16 of the first housing 11. This exterior panel 13 is used to seal the handle mounting area, ensuring that the handle 12 is aesthetically pleasing and secure after installation. A through-hole 1b is provided in the exterior panel 13, through which the handle 12 passes and extends into the interior of the first housing 11. A support device 7 is provided within the first housing 11 for supporting the handle 12. The handle 12, extending into the first housing 11 through the through-hole 1b, is supported by the support device 7.

[0090] In this embodiment, in order to realize the installation of handles 12 of different specifications, the through hole 1b is constructed to allow different handles 12 to pass through, so as to meet the installation requirements of handles of different widths. Figures 9-11 As shown, the support device 7 includes a first bracket 71 and a second bracket 72. The first bracket 71 is fixedly arranged in the first box body 11, and the second bracket 72 of different heights is detachably connected to the first bracket 71, so that the height of the support device 7 can be changed by replacing different second brackets 72 to meet the installation requirements of handles of different heights. Specifically, a connecting portion 73 is provided on the top surface of the first bracket 71. The connecting portion 73 is specifically a mounting hole for connecting to the second bracket 72 through fasteners such as bolts to achieve a detachable connection between the first bracket 71 and the second bracket 72. The height of the support device 7 can be changed by connecting or not connecting the second bracket 72, and by connecting second brackets 72 of different heights to meet the installation requirements of handles of different heights.

[0091] The size of the through hole 1b is greater than or equal to the maximum width of all handles 12 that may need to be installed, so that all handles 12 that may need to be installed can pass through. At this time, the upper surface of the exterior panel 13 constitutes the exterior surface of all handles 12 that may need to be installed, that is, all handles 12 that may need to be installed have a unified exterior surface. The top surface height of the first bracket 71 is equal to the top surface height of the support device 7 corresponding to the handle 12 with the lowest installation position (i.e., the top surface height of the required support device 7 is the lowest) among all handles 12 that may need to be installed. This allows the height of the support device 7 to be changed by connecting or not connecting the second bracket 72 on the upper side of the first bracket 71, as well as connecting second brackets 72 of different heights, to meet the installation requirements of handles of different heights.

[0092] For ease of understanding, here we combine Figure 10-12 , taking the situation where four handles 12 of different specifications may need to be installed as an example, the arrangement of the support device 7 in this embodiment is described.

[0093] like Figure 10-12 As shown, the four different sizes of handles 12 are Figure 10 The first handle 121, the second handle 122, the third handle 123 and the fourth handle 124 are shown in sequence from right to left. Figure 10 As shown, the KO points corresponding to the four handles 12 (i.e., the points corresponding to the palm of the hand when the handle 12 is normally operated) are Figure 10 are at the same height (e.g. Figure 10 Moreover, the four handles 12 have a uniform outer surface, that is, the outer surfaces of the outer panels 13 corresponding to the four handles 12 are at the same height (indicated by the dotted line K in FIG. Figure 10 represented by the straight line P). Figure 10The four dotted rectangular boxes T in the figure represent the possible height ranges of the outer surfaces corresponding to the four handles 12. The four dotted rectangular boxes overlap, which indicates that the four handles 12 can be constructed to have a uniform outer surface. However, the top surface height positions of the support device 7 corresponding to the four handles 12 (i.e., the installation positions of the four handles 12) are different. Among them, the top surface height positions of the support device 7 corresponding to the first handle 121, the second handle 122, the third handle 123 and the fourth handle 125 are as follows: Figure 9 As shown in H1, H2, H3 and H4 in FIG, it can be seen from the comparison that the top surface of the support device 7 corresponding to the second handle 122 is the lowest, and the top surfaces of the support devices 7 corresponding to the first handle 121, the third handle 123 and the fourth handle 124 are all higher than the top surface of the support device 7 corresponding to the second handle 122. In this case, the installation position of the second handle 122 is the lowest, and the top surface height of the support device 7 corresponding to the second handle 12 is the lowest. Therefore, in this embodiment, the top surface height position of the support device 7 corresponding to the second handle 122 is used as the top surface height position of the first bracket 71 (which can be called the universal mounting surface of the handle). Figure 10 (indicated by the dotted line Q in FIG), and the first bracket 71 is accordingly arranged. Figure 11 As shown, when the second handle 122 needs to be installed, the second handle 122 can be directly connected to the connecting portion 73 without using the second bracket 72. Figure 12 As shown, when the first handle 121 needs to be installed, the second bracket 72 that can make up for the height difference between the top surfaces of the support device 7 corresponding to the first handle 121 and the second handle 122 can be connected to the connecting portion 73, and the second bracket 72 is located above the first bracket 71, so that the support device 7 can meet the installation requirements of the first handle 121. Similarly, when the third handle 123 or the fourth handle 124 needs to be installed, a second bracket 72 of a different height can be connected above the first bracket 71 to accommodate the third handle 123 and the fourth handle 124.

[0094] It can be seen that the main box 1 of this embodiment has good versatility and later expandability, and can flexibly meet the installation requirements of handles 12 of different widths and heights. This is conducive to achieving lightweight design, effectively reducing mold cost investment, reducing manufacturing and assembly difficulty, and realizing the universal application of the control box for a variety of products. It strongly supports the selection and matching work of other systems and greatly reduces related manufacturing and maintenance costs.

[0095] The connecting member 31 and the linkage mechanism 32 are used to connect the main box 1 and the seat to achieve linkage and relative movement between the main box 1 and the seat. Figure 1-Figure 3As shown, in this embodiment, the main box 1 is installed on a linkage mechanism 32 and is fixed to the seat by a connector 31, forming a structure that is linked to the seat. Moreover, the linkage mechanism 32 includes a first adjustment mechanism 33 and a second adjustment mechanism 34. The first adjustment mechanism 33 includes a slide rail 35, which extends along the front-to-back direction, so that the first adjustment mechanism 33 enables the main box 1 to move forward and backward relative to the seat. The second adjustment mechanism 34 includes a scissor-type lifting mechanism 36, so that the second adjustment mechanism 34 enables the main box 1 to move up and down relative to the seat. It can be seen that the linkage mechanism 32 of this embodiment enables the main box 1 to move forward and backward and up and down relative to the seat. Since, under the action of the connector 31 and the linkage mechanism 32, the main box 1 can move forward and backward with the seat, and can also move forward and backward and up and down relative to the seat, the main box 1 can meet the operating needs of people of different body shapes and has good operating comfort.

[0096] The auxiliary box 2 is used to realize the installation of the electrical device 22. Figure 5-Figure 6 As shown, in this embodiment, the auxiliary box 2 includes a second box body 21 and an electrical device 22. The second box body 21 includes a top cover 16, a shell 17 and a frame 18. The top cover 16 of the second box body 21 is set on the top of the shell 17. The frame 18 of the second box body 21 is set in the chamber formed by the top cover 16 and the shell 17. The electrical device 22 is set on the top cover 16 of the second box body 21 for user operation. Figure 6 As can be seen, in this embodiment, the electrical device 22 includes electrical components such as an emergency stop 23, a skipping switch 24, a start switch 25, a charging port 26, an alarm 27, a radio 28, and a forced start 29. These electrical components are all disposed on the top cover 16 of the second box body 21.

[0097] Specifically, if Figure 6 As shown, in this embodiment, the top cover 16 of the second box body 21 includes a first cover body 43 and a second cover body 44, which are connected in sequence from front to back. The emergency stop member 23 and part of the skipping switch 24 are arranged on the first cover body 43, while the other part of the skipping switch 24, the start switch 25, the charging port 26, the alarm 27, the radio 28 and the forced start 29 are all arranged on the second cover body 44. Figure 6 As can be seen, the second cover 44 is arranged roughly horizontally, while the first cover 43 gradually tilts upward from the back to the front, appearing tilted. The angle between the first cover 43 and the horizontal plane is 5-10 degrees. At this time, the first cover 43 is slightly tilted, which facilitates the driver's hand pressing and operation, meets the observation needs, and can provide a better comfort experience.

[0098] Continue to see Figure 6In this embodiment, the second box body 21 is further provided with a mounting portion 45 and an intercom 42. The mounting portion 45 is used to mount the loudspeaker 41, and the loudspeaker 41 is detachably connected to the mounting portion 45 so as to adapt the loudspeaker 41 according to actual needs. Specifically, Figure 5 As shown, in this embodiment, the loudspeaker 41 is arranged on one side of the left and right direction of the second box body 21. The intercom 42 is arranged on the rear side of the second box body 21.

[0099] In this embodiment, the auxiliary box 2 serves as a separate modular body. It only needs to replace the top cover 16 of the second box body 21 and assemble it with the shell 17. The overall size is smaller, and it can be combined with the installation space and installation position of various electrical components to form auxiliary boxes with various configurations, realizing modular design.

[0100] Moreover, if Figure 3-Figure 9 As shown, in this embodiment, the auxiliary box 2 is connected to one side of the main box 1 along the left and right directions in a suspended manner, and is installed and fixed using a force-bearing lever structure, so that the auxiliary box 2 is placed in the air, which can effectively save the overall space. Together with the main box 1, it is linked with the seat and moves relative to the seat, thereby improving the convenience and comfort of operation.

[0101] Specifically, in this embodiment, Figure 4 As shown, two slots 19 are provided on one side of the left and right direction of the first box body 11 of the main box 1. The two slots 19 are spaced apart along the front and rear directions. Figure 5 As shown, two plug-in plates 5 are provided on the side of the second box body 21 of the auxiliary box 2 facing the main box 1. These two plug-in plates 5 correspond one-to-one to the two slots 19, and each plug-in plate 5 has the same structure, including a first plate body 51 and a second plate body 52 connected in an L-shape, the first plate body 51 extending horizontally, and the second plate body 52 extending vertically downward from the first plate body 51. A first hole 53 and a second hole 54 are provided on the first plate body 51 and the second plate body 52, respectively. Among them, the first hole 53 is a closed circular hole, which passes through the first plate body 51 along the thickness direction (i.e., the up and down direction) of the first plate body 51. The second hole 54 is a U-shaped hole, which is a U-shaped hole. The second hole 54 is located at the lower end of the second plate body 52, and passes through the second plate body 52 along the thickness direction (i.e., the left and right direction) of the second plate body 52, and the U-shaped opening faces downward, that is, a notch 55 is provided at the lower end of the second hole 54.

[0102] With the cooperation of the two plug-in boards 5 and the main box 1, the auxiliary box 2 is suspended on one side of the main box 1 in the left and right directions. Figure 7 and Figure 8As shown, in this embodiment, a bending plate 6 corresponding to the two plug plates 5 is provided in the first box body 11 of the main box 1. After the two plug plates 5 are inserted into the two slots 19 respectively, they correspond to the two bending plates 6 one by one. The first plate body 51 of each plug plate 5 is located above the horizontal part of the corresponding bending plate 6, and the second plate body 52 of each plug plate 5 is located on the inner side of the vertical part of the corresponding bending plate 6, and the horizontal and vertical parts of the bending plate 6 are respectively provided with connecting holes corresponding to the first hole 53 and the second hole 54. In this way, the first fastener 81 is inserted into the first hole 53 and the connecting hole corresponding to the horizontal part of the bending plate 6 in the up and down direction to lock it, and the second fastener 82 is inserted into the second hole 54 and the connecting hole corresponding to the vertical part of the bending plate 6 in the left and right direction to lock it. Then, the plug plates 5 and the first box body 11 can be coupled and locked to form a tight and stable force-bearing lever form, thereby realizing the hanging connection of the auxiliary box 2 on one side of the left and right directions of the main box 1. Specifically, in this embodiment, the inserting plate 5 is located on the frame 18 of the auxiliary box 2, the bending plate 6 is located on the frame 18 of the main box 1, and the first fastener 81 and the second fastener 82 both include bolts.

[0103] By adopting the above-mentioned connection structure, the auxiliary box 2 can be suspended on one side of the main box 1 in the left and right directions, saving space, and effectively suppressing the rotation of the suspended auxiliary box 2, so as to achieve a stable setting of the auxiliary box 2 in the left and right directions of the main box 1. Moreover, the assembly is more convenient and efficient.

[0104] The assembly process of the control box 10 of this embodiment can be roughly as follows:

[0105] Connect the housing 17 of the auxiliary box 2, the intercom 42 and the frame 18 through fasteners, and fix the loudspeaker 41 to the housing 17 of the auxiliary box 2 through fasteners;

[0106] The electrical components such as the skipping switch 24, the emergency stop 23, the start switch 25, the charging port 26, the alarm 27, the radio 28 and the forced start 29 are installed on the top cover 16 of the auxiliary box 2. The installed top cover 16 of the auxiliary box 2 is assembled with the housing 17 of the auxiliary box 2 and fixed with fasteners to form the auxiliary box 2. In this process, the top cover 16 of the auxiliary box 2 with different configurations can be replaced according to different configuration requirements and electrical component sizes to obtain auxiliary boxes 2 with different configurations.

[0107] Connect the housing 17 of the main box 1 to the frame 18 through fasteners;

[0108] Place the auxiliary box 2 on one side of the main box 1, insert the plug plate 5 of the auxiliary box 2 into the slot 19, and insert the first fastener 81 into the first hole 53 and the connecting hole on the horizontal part of the bent plate 6, and fix it with a nut. Similarly, insert the second fastener 82 through the second hole 54 and the connecting hole on the vertical part of the bent plate 6 in sequence to fix it, forming a stable force-bearing lever structure, so that the frame 18 of the auxiliary box 2 is suspended on the frame 18 of the main box 1. Afterwards, connect the top cover 16 of the main box 1 with the frames 18 of the main box 1 and the auxiliary box 2 through fasteners to realize the suspension of the auxiliary box 2 on the side of the main box 1;

[0109] The handle 12 and the elbow support 14 are connected to the assembled main box 1 through fasteners, and the main box 1 is fixed to the linkage mechanism 32 and connected to the seat through the connecting piece 31.

[0110] It can be seen that the control box 10 of this embodiment has a simple structure, is easy to assemble, saves space, is convenient to operate, and has strong versatility, which can meet different configuration requirements. This is conducive to improving the compactness of the cab layout, realizing the universalization of cab molds for different products, improving mold utilization, saving mold cost investment, reducing manufacturing and assembly difficulty, and realizing lightweight and intensive product design.

[0111] Next, we will introduce Figure 13 In order to simplify the description, only the differences between the second embodiment and the first embodiment are described here. For matters not described, reference can be made to the first embodiment for understanding.

[0112] like Figure 13 As shown, the main difference between this second embodiment and the first embodiment is that there are two auxiliary boxes 2 instead of one. The two auxiliary boxes 2 are arranged on the same side of the main box 1 in the left-right direction and are arranged side by side in the left-right direction. The first auxiliary box 2 is suspended from the main box 1, while the second auxiliary box 2 is suspended on the side of the first auxiliary box 2 away from the main box 1.

[0113] Next, we will introduce Figure 14 In order to simplify the description of the third embodiment shown, only the differences between the third embodiment and the first embodiment are described. For the parts not described, reference can be made to the first embodiment for understanding.
