Description

Technical Field

[0001] The present application relates to the agricultural field, and more specifically, to a limiting component and an agricultural machine. Background Art

[0002] With the development of agricultural equipment, many agricultural machines are equipped with display devices to display the working status, working environment and other information of the agricultural machinery to users, and can provide an operation interface for users to directly operate and control the agricultural machinery. Existing display devices are usually fixed by adhesives, or with the help of external locks and other components. These components are often set around the display device and the edge of the light-emitting side to fix the display device. Since agricultural machinery is usually used in outdoor environments and exposed to sunlight or rain for a long time, the viscosity of the adhesive will decrease, causing the display device to fall off, and the gluing method lacks reusability, and the external fixing components may loosen due to reduced elasticity or stability, which also causes the display device to fall off easily.

[0003] Based on this, how to provide a stable and easily disassembled display device fixing device is an issue that needs to be solved urgently. Summary of the invention

[0004] The present application provides a limiter and an agricultural machine, wherein the limiter can improve the stability of the fixation of a display device, improve the convenience of installation and disassembly, help reduce the loss of the limiter, and enhance the user experience.

[0005] In a first aspect, a limiting member is provided, which is used to fix a display device, and the limiting member includes a buckle, a shell, a first magnet, a spring pin and an elastic member; the buckle is provided with a fixing portion and a buckling portion, the buckling portion is used to buckle with the spring pin, and the fixing portion is used to fix the display device; the shell is provided with a accommodating cavity, the first magnet is arranged in the accommodating cavity, one end of the elastic member is connected to one side of the first direction of the first magnet, and the other end of the elastic member is fixed to the shell; the accommodating cavity is provided with a through hole, the through hole is arranged on the first side of the second direction of the first magnet, the spring pin is arranged in the through hole, The needle extends along a second direction, and the second direction is perpendicular to the first direction; the first end of the elastic needle along the second direction includes a first inclined surface, and the second end includes a second inclined surface, a third inclined surface is provided on the first side of the first magnet, and the buckle of the buckle includes a fourth inclined surface; the first inclined surface, the second inclined surface, the third inclined surface and the fourth inclined surface are all parallel, and the third inclined surface abuts against the second inclined surface; the elastic member moves the first magnet along the first direction, and the first magnet makes the elastic needle approach the buckle along the second direction through the third inclined surface, so as to buckle the first end of the elastic needle into the buckle, so that the fixing part fixes the display device.

[0006] Through the technical solution of the embodiment of the present application, the various components of the limiter cooperate with each other, and the user can easily move the buckle, thereby causing the components to interact and move, so that the spring pin limits the movement of the buckle, and the movement between the buckle and the shell is limited, thereby achieving the fixation of the limiter to the display device. Among them, the fixing part abuts against the screen of the display device to fix the display device, thereby reducing friction and damage to the screen, and the through hole is used to accommodate the spring pin and cooperate with its shape to limit the spring pin from moving in the second direction, but not moving in other directions, which is conducive to improving the stability of the buckle and reducing the possibility of loosening of the limiter and damage to the display device.

[0007] The embodiments of the present application can quickly and conveniently fix the display device, have good stability, and will not cause damage to the stopper, which greatly improves the stability and reusability of the display device fixing structure, and helps to increase the service life of the agricultural machinery with the display device. The stopper provided in the embodiments of the present application can improve the convenience of fixing the display device, improve the user experience, and help to enhance the stability of the agricultural machinery display device.

[0008] In combination with the first aspect, in a possible implementation, the limiting member also includes a second magnet; the second magnet moves the first magnet along the first direction, and the first magnet causes the elastic pin to move away from the snap-fitting portion along the second direction through the third inclined surface, so that the first end of the elastic pin leaves the snap-fitting portion, causing the fixing portion to detach from the display device.

[0009] In the technical solution of the embodiment of the present application, the second magnet is arranged outside the stopper, for example, it can be arranged in an independent disassembly device and held by an operator, or arranged on a device to which the stopper is attached, and starts working when the stopper is disassembled. The second magnet is made of the same material as the first magnet, and the polarity between the two opposite faces of the two magnets is the same, so that the first magnet moves along the first direction by the property that like-charged magnets repel each other.

[0010] By arranging a second magnet on the outside of the limit member, the structure of the limit member that is in a locked state can be maintained without damaging the structure, and the first magnet inside the shell can be moved from the outside, thereby improving the convenience of using the limit member, and the limit member can be used repeatedly, increasing reusability, thereby effectively improving the user experience.

[0011] In combination with the first aspect, in a possible implementation, a fifth inclined surface is provided on a side of the buckle portion close to the display device. When the buckle moves close to the display device, the fifth inclined surface presses against the first inclined surface of the spring pin to pass over the first end of the spring pin so that the spring pin is aligned with the buckle portion in the second direction; the fifth inclined surface is parallel to the first inclined surface.

[0012] In the technical solution of the embodiment of the present application, when the buckle moves close to the display device, the fifth inclined surface presses against the first inclined surface of the spring pin to pass over the first end of the spring pin, so that the spring pin and the buckle part are aligned in the second direction, and the fifth inclined surface is parallel to the first inclined surface. Wherein, alignment in the second direction means that the projections of the spring pin and the buckle part in the second direction overlap or partially overlap, and at this time, the first end of the spring pin can be buckled in the space of the buckle part to achieve the fixation of the buckle, thereby improving the stability of the fixation of the limiter.

[0013] In combination with the first aspect, in a possible implementation, the edge of the buckle in the third direction is connected to the shell through a slide rail; the buckle moves through the slide rail to get closer to or away from the display device; the third direction is perpendicular to the first direction and the second direction.

[0014] In the technical solution of the embodiment of the present application, the extension direction of the slide rail is parallel to the first direction, and is arranged at the edge of the buckle in the third direction close to the shell. Correspondingly, a guide rail matching the slide rail is arranged at the position corresponding to the shell and the slide rail, and the slide rail can be engaged with the guide rail so that the buckle moves along the first direction to achieve the limit of the buckle. The buckle can move on the shell through the slide rail, and the guide rail of the shell can provide the slide rail with the limit and guidance of the moving direction, which is conducive to improving the convenience and stability of the limiter buckle engagement and reducing the loss caused by operational errors.

[0015] In combination with the first aspect, in a possible implementation, the limiting member also includes a stopper, which is disposed in the accommodating cavity of the shell, and the stopper is disposed in the first direction of the first magnet and away from the side of the elastic member, and the stopper is used to limit the first magnet.

[0016] Through the technical solution of the embodiment of the present application, the stopper is set on one side of the first magnet, and when the first magnet moves along the first direction and away from the display device, its moving distance can be limited, ensuring that the fourth inclined surface of the first magnet can cooperate with the second inclined surface of the spring pin, and realizing appropriate interaction to engage or disassemble the limiter. The stopper can provide protection for the first magnet and other components to prevent loosening or falling during movement, which is conducive to improving the stability of the limiter in fixing the screen.

[0017] Optionally, the stopper may be an independent component, which is placed on the side of the first magnet away from the elastic component when the limiting member is assembled, and fixed to the shell by a hot melt process, or the stopper may be integrally formed with the shell of the limiting member.

[0018] In combination with the first aspect, in a possible implementation manner, the material of the buckle is an alloy material formed by mixing plastic polycarbonate and acrylonitrile-butadiene-styrene copolymer.

[0019] In combination with the first aspect, in a possible implementation manner, the elastic member is a spring, and a deformation direction of the spring is parallel to the first direction.

[0020] Optionally, the elastic member may also be other elastic components such as a bellows with annular corrugations made of a cylindrical thin-walled tube, a diaphragm box with concentric annular corrugations (or no corrugations) made of a circular sheet, etc.

[0021] In combination with the first aspect, in a possible implementation manner, the material of the first magnet and the second magnet is at least one of a ferromagnet and a ferrite magnet.

[0022] In combination with the first aspect, in a possible implementation manner, the material of the spring pin is stainless steel.

[0023] In combination with the first aspect, in a possible implementation manner, the material of the shell is plastic.

[0024] In a second aspect, an agricultural machine is provided. The agricultural machine includes a display device and a limiting member as in any implementation of the first aspect, wherein the limiting member is used to fix the display device.

[0025] In the technical solution of the embodiment of the present application, the limiting member includes four clips and corresponding components in other shell accommodating cavities, which are respectively arranged at the corners of the display device. The setting of multiple clips can fully provide support for the display device, ensure the screen stability of the agricultural machinery, and improve the service life and safety of the equipment.

DETAILED DESCRIPTION

[0027] The technical solution in this application will be described below in conjunction with the accompanying drawings.

[0028] The limiting member involved in the present application is used to fix the display device and can be applied to a variety of fields and scenarios. As an example, the limiting member can be applied to electronic devices with display requirements, including but not limited to navigation agricultural machinery, vehicle-mounted equipment, audio equipment, etc. The present application does not specifically limit the specific type of electronic device where the limiting member is located.

[0029] Exemplarily, the present application is applicable to agricultural machinery, which can be used in multiple links of agriculture, such as sowing, fertilizing, spraying, and harvesting, etc. The application of agricultural machinery can greatly improve agricultural production efficiency, reduce labor costs, and improve the yield and quality of crops.

[0030] Figure 1 A schematic structural block diagram of an agricultural machinery system 100 provided in an embodiment of the present application is shown.

[0031] like Figure 1 As shown, the agricultural machinery system 100 may include: a sensor 110 , a control system 120 , a navigation algorithm 130 , a communication system 140 and a user interface 150 .

[0032] Specifically, the sensor 110 may include multiple types. As an example and not limitation, Figure 1 As shown, the sensor 110 may include: a laser radar sensor 111, a visual sensor 112, an ultrasonic sensor 113, an infrared sensor 114, and a global positioning system (GPS), etc. The various types of sensors can be used to assist the agricultural machinery to more accurately identify the current working environment and locate the current position, which is beneficial for the user to more accurately control the path of the agricultural machinery and improve the working efficiency of the agricultural machinery.

[0033] The control system 120 may include: a controller or a processor. As an example, the control system 120 may include: a central processing unit (CPU), a micro controller unit (MCU), an embedded system, etc. The control system 120 may receive data from various types of sensors, execute navigation algorithms and make decisions, and control the operation of the agricultural machinery.

[0034] The navigation algorithm 130 is a software module, which can be stored in a storage unit in the control system 120, or the agricultural machinery system 100 can include an independent storage unit for storing the navigation algorithm 130. The navigation algorithm 130 can be used to execute path planning, avoidance algorithm, adaptive navigation, etc. of the agricultural machinery.

[0035] The communication system 140 is used to realize data communication between the agricultural machinery and the user or the server (operation center). The communication system 140 can be a wireless communication system, such as a mobile communication system, and the mobile communication system includes: 3G / 4G / 5G communication system, etc. The user or the server can control the agricultural machinery through the communication system 140, and the communication system 140 can also transmit the location, status and operation data of the agricultural machinery to the user or the server in real time for monitoring and analysis.

[0036] The user interface 150 may be installed in a display device of the agricultural machine to display navigation information, the operation status of the agricultural machine, etc. The user may interact with and control the agricultural machine through the user interface 150 .

[0037] Figure 2 FIG. 2 shows a schematic top view of an agricultural machine 200 provided in an embodiment of the present application. As an example, the agricultural machine 200 can be used to carry Figure 1 The agricultural machine system 100 is shown.

[0038] like Figure 2 As shown, the agricultural machine 200 includes a display device 210 and a fixing component 220, and the fixing component 220 is used to fix the display device 210. The display device 210 can be used to install, for example, Figure 1 A user interface 150 is shown in the agricultural machine system 100 .

[0039] The display device 1 210 is usually fixed in the agricultural machine 1 200 using adhesive materials, which are pasted on the surface of other parts of the agricultural machine 1 200. For example, the adhesive materials can be 3M adhesive, UV adhesive, optical tape, etc. In addition to using adhesive materials, an external fixing device such as the fixing component 220 can also be used. This type of display device is set around the display device 1 210 and the edge of the light-emitting side to fix the display device 1 210 on the main body of the agricultural machine. The fixing component 220 can include but is not limited to a spring buckle, a ring buckle, a U-shaped buckle, etc.

[0040] Taking the agricultural machine 200 as an example, since the equipment is usually in an outdoor environment, after being exposed to the sun or rain, the adhesive material fixing the display device 210 is prone to reduced viscosity, causing the equipment to fall off, and the adhesive material fixing method lacks reusability. The agricultural machine 200 that uses the fixing component 220 to fix the display device 210 may have reduced elasticity or stability and easy loosening after long-term use, causing the display device 210 to fall off, and some fixing components 220 are difficult to disassemble.

[0041] Based on the above problems, the present application provides a limiter for fixing a display device, which can facilitate installation and disassembly while ensuring the stability of the screen, thereby improving the reusability and convenience of the limiter.

[0042] Figure 3 A partial cross-sectional schematic diagram of a position limiting member 300 provided in an embodiment of the present application is shown.

[0043] like Figure 3 As shown, the stopper 300 includes a buckle 310 and a housing 320. Other components are arranged between the two components, including a first magnet 330, a spring pin 340 and an elastic member 350, which are used to cooperate with the buckle 310 and the housing 320 for buckling and disassembly to achieve the fixation of the stopper 300 to the display device.

[0044] For the convenience of description, a coordinate system is established in the present application, wherein the x, y, and z directions are perpendicular to each other, the x direction can be understood as the arrangement direction of the first magnet 330 and the elastic member 350 (i.e., the first direction), the y direction can be understood as the arrangement direction of the first magnet 330 and the elastic pin 340 (i.e., the second direction), and the x direction is perpendicular to the y direction and parallel to the x direction. Figure 3 In the cross section of the stopper 300 shown, the z direction (i.e., the third direction) is perpendicular to the x direction and the y direction. The coordinate axes mentioned in this application are based on this coordinate system, and the first direction represents the x direction, the second direction represents the y direction, and the third direction represents the z direction.

[0045] See also Figure 3 The buckle 310 includes a buckling portion 311 and a fixing portion 312. The buckling portion 311 is used to buckle with the elastic pin 340, and the fixing portion 312 is used to fix the display device. Figure 3 The side of the fixing portion 312 facing the housing 320 is parallel to the screen of the display device, and the projection of the fixing portion 312 in the first direction partially overlaps with the display device. When the buckle 310 is buckled with the housing 320, the fixing portion 312 abuts against the display device and covers the screen of the display device, thereby fixing the display device. The fixing portion 312 can abut against the screen of the display device to fix the display device, and can reduce friction and damage to the screen.

[0046] like Figure 3 As shown, the buckle part 311 includes a fourth inclined surface, and a wall near the side of the display device, and the wall extends along the second direction. The buckle part 311 forms a space through the fourth inclined surface and the wall, and the shape of the space can match the shape of the elastic pin 340 and can accommodate the elastic pin 340, so as to buckle the buckle 310 with the elastic pin 340 to achieve full fitting fixation and fixation of the buckle 310. Exemplarily, the inner diameter of the space in the buckle part 311 can be slightly larger than or equal to the outer diameter of the elastic pin 340, so as to reduce wear between components while ensuring stability.

[0047] The buckle 311 and the fixing part 312 together form a buckle 310, which is connected to the housing 320. After buckling, a closed structure is formed outside the display device to fix the display device. Optionally, the buckle 310 is made of hard alloy, such as an alloy material mixed with plastic polycarbonate (PC) and acrylonitrile-butadiene-styrene (ABS), also known as PC / ABS alloy.

[0048] Continue to see Figure 3 , a housing cavity is provided in the housing 320, and the first magnet 330 and the elastic member 350 are provided in the housing cavity. In the embodiment of the present application, the housing cavity is a cavity structure for accommodating components. An opening is provided on a side of the housing cavity away from the display device, so that the internal components of the stopper 300 can be placed in the housing cavity when the stopper 300 is installed, and the opening can be covered by the buckle 310 to achieve a closed structure. Optionally, the material of the housing 320 can be plastic, for example.

[0049] The first magnet 330 and the elastic member 350 are arranged in a first direction inside the accommodating cavity. Specifically, one end of the elastic member 350 is connected to one side of the first direction of the first magnet 330, and the other end of the elastic member 350 is fixed to the shell 320. The elastic member 350 is fixedly connected to the shell 320, and can not move in other directions when subjected to the extrusion force in the first direction, so as to avoid the displacement of the internal parts of the limiter 300. In addition, the elastic member 350 abuts against the first magnet 330, and can apply a force to the first magnet 330 to make it move along the first direction. It should be understood that the connection between the elastic member 350 and the first magnet 330 can be fixed to each other, or it can be non-fixed, that is, separately arranged.

[0050] Optionally, the elastic member 350 may be a spring whose deformation direction is parallel to the first direction. In addition to the spring, the elastic member 350 may also be other elastic components such as a bellows with annular corrugations made of a cylindrical thin-walled tube, a diaphragm box with concentric annular corrugations (or no corrugations) made of a circular sheet, etc.

[0051] like Figure 3 As shown, a through hole is also provided in the accommodating cavity of the shell 320, and the through hole is provided on one side (i.e., the first side) in the second direction of the first magnet 330, for accommodating an elastic pin 340, which is provided in the through hole and extends along the second direction. Exemplarily, the elastic pin 340 can be a cylindrical component extending along the second direction, and correspondingly, the through hole on the shell 320 is a cylindrical channel extending along the second direction and penetrating the shell 320, and the inner wall of the buckle 311 is a cylindrical groove extending along the second direction, and includes a fourth inclined surface that matches the first inclined surface of the first end of the elastic pin 340. When the buckle 310 is buckled with the shell 320, the first inclined surface of the elastic pin 340 is connected to the buckle 311, and the second inclined surface is connected to the first magnet 330.

[0052] It is understandable that the above connection methods are all non-fixed connections. Optionally, the spring pin 340 can also be in other shapes, such as a rectangular or elliptical component extending along the second direction, and the through hole and the buckle portion 311 are also correspondingly set to be a rectangular or elliptical component extending along the second direction. In the embodiment of the present application, the through hole is used to accommodate the spring pin 340 and match its shape to limit the spring pin 340 from moving in the second direction, but not in other directions, which is conducive to improving the stability of the buckle 310 and reducing the possibility of loosening of the limiter 300 and damage to the display device.

[0053] See also Figure 3 The spring pin 340 is provided with a first end and a second end along the second direction, the first end is an end close to the buckle 310, and the first end includes a first inclined surface, and the second end is an end close to the first magnet 330, and the second end includes a second inclined surface. The shape of the first end of the spring pin 340 is the same as the shape of the space in the buckle 311, that is, when the two are buckled, the fourth inclined surface of the buckle 311 abuts against the first inclined surface of the spring pin 340, and the outer wall shape of the first end of the spring pin 340 extending along the second direction abuts against the inner wall of the buckle 311. The shape matching can enhance the reliability of the buckle 310 and improve the fixing performance of the display device.

[0054] A third inclined surface is disposed on the first side of the first magnet 330, and the third inclined surface is parallel to the fourth inclined surface of the aforementioned buckling portion 311. Figure 3It can be seen that in the embodiment of the present application, the cross-sectional shape of the first magnet 330 in the xy direction is a combination of a rectangle and a right-angled trapezoid, and the hypotenuse of the right-angled trapezoid is the fourth inclined plane, and it abuts against the second inclined plane of the elastic pin 340. It can be understood that this connection method is a non-fixed connection. The shape of the first magnet 330 matches the shape of the second end of the elastic pin 340, and the elastic pin 340 can be acted on by this shape to move it. The first magnet 330 is not limited to the shape shown in the figure. Optionally, the material of the first magnet 330 can be at least one of a ferromagnet, a ferrite magnet, a rare earth magnet, etc. The present application does not specifically limit the material selection of the magnet.

[0055] Continue to see Figure 3 The first and second inclined surfaces of the spring pin 340, the third inclined surface of the first magnet 330, and the fourth inclined surface of the buckling portion 311 are all parallel, and the second inclined surface of the spring pin 340 abuts against the third inclined surface of the first magnet 330. Optionally, the abutment method is a non-fixed connection. Through the parallel setting and abutment between different inclined surfaces, the components in the limiter 300 can cooperate with each other to move, realize buckling or disassembly, and improve the reusability and convenience of the limiter 300.

[0056] like Figure 3 As shown, in addition to the fourth inclined surface, the buckle 311 also has a fifth inclined surface on the side close to the display device. When the buckle 310 moves close to the display device, the fifth inclined surface presses against the first inclined surface of the elastic pin 340 to pass over the first end of the elastic pin 340, so that the elastic pin 340 is aligned with the buckle 311 in the second direction, and the fifth inclined surface is parallel to the first inclined surface. In the embodiment of the present application, alignment in the second direction means that the projections of the elastic pin 340 and the buckle 311 in the second direction overlap or partially overlap, and at this time, the first end of the elastic pin 340 can be buckled in the space of the buckle 311 to achieve the fixation of the buckle 310. This embodiment can improve the stability of the fixation of the buckle 310.

[0057] Based on the components in the above-mentioned limiter 300, the elastic member 350 moves the first magnet 330 along the first direction, and the first magnet 330 makes the spring pin 340 approach the buckling part 311 along the second direction through the third inclined surface, so as to buckle the first end of the spring pin 340 in the buckling part, so that the fixing part fixes the display device. Through the cooperation between the buckle 311, the spring pin 340 and the first magnet 330 on the buckle 310, the buckle 310 and the spring pin 340 can be conveniently buckled and disassembled. The implementation method of the present application can quickly and conveniently fix the display device, has good stability, and will not cause damage to the limiter 300, which greatly improves the stability effect and reusability of the display device fixing structure, and helps to improve the service life of the agricultural machinery with the display device.

[0058] Figure 4 A partial schematic diagram of another limiting member 400 provided in an embodiment of the present application is shown. Figure 4 The stopper 400 shown includes Figure 3 The same parts of the stopper 300 are shown, but some parts are different due to different viewing angles. Figure 4 It is blocked and not shown.

[0059] like Figure 4 As shown, the edge of the buckle 410 in the third direction is connected to the housing 420 via the slide rail 460, and the buckle 410 moves through the slide rail 460 to get closer to or farther away from the display device. The extension direction of the slide rail 460 is parallel to the first direction, and is arranged at the two side edges of the buckle 410 in the third direction close to the housing 420. Correspondingly, guide rails 461 matching the slide rails 460 are respectively arranged at the corresponding positions of the housing 420 and the slide rails 460. The slide rails 460 can be engaged with the guide rails 461 so that the buckle 410 can only move in the first direction, but not in other directions, so as to limit the buckle 410.

[0060] Optionally, the slide rail 460 may be, for example, a strip groove parallel to the screen of the agricultural machinery display device and extending along the first direction, and correspondingly, the guide rail 461 is a strip protrusion that can be embedded in the groove of the slide rail 460 to cooperate with the slide rail 460. The cross-sectional shape of the slide rail 460 may be rectangular, trapezoidal or other shapes, and the cross-sectional shape of the guide rail 461 may be able to cooperate with the slide rail 460, and this application does not make any specific limitation on this.

[0061] In the embodiment of the present application, the buckle 410 can move on the shell 420 through the slide rail 460, and the guide rail 461 of the shell 420 can provide limitation and guidance for the moving direction of the slide rail 460 of the buckle 410, which is beneficial to improve the convenience and stability of the fastening of the limit member 400 and reduce the loss caused by operational errors.

[0062] Reference below Figure 5 , the buckling process of the limiting member 400 is described.

[0063] Figure 5 A partial cross-sectional schematic diagram of another limiting member 500 provided in an embodiment of the present application is shown. Figure 5 The stopper 500 shown includes Figure 3 The same components as the stopper 300 shown, Figure 4 The slide rail 460 and the guide rail 461 in the stopper 400 are shown in FIG. Figure 5 Not shown in the figure, detailed description can be found in the previous text, and will not be repeated in this embodiment.

[0064] When the buckle 510 and the housing 520 are buckled, the buckle 510 is engaged with the guide rail (not shown in the figure) on the housing 520 through the slide rail (not shown in the figure), and the buckle 510 is subjected to a force F parallel to the first direction and directed to the display device. After the buckle 510 is subjected to the force, it moves along the first direction through the slide rail to approach the display device. During the movement, the fifth inclined surface of the wall of the buckling portion 511 abuts against the first inclined surface of the first end of the elastic pin 540, so that the elastic pin 540 moves along the second direction and in the direction of the first magnet 530. Since the second inclined surface of the second end of the elastic pin 540 abuts against the third inclined surface of the first magnet 530, the elastic pin 540 causes the first magnet 530 to move along the first direction and in the direction of the elastic member 550 through the second inclined surface, and then the first magnet 530 causes the elastic member 550 to be subjected to the extrusion force and deformed along the first direction. When the spring pin 540 is aligned with the buckle portion 511 in the second direction, that is, the projections of the spring pin 540 and the buckle portion 511 in the second direction overlap or partially overlap, the wall of the buckle portion 511 no longer abuts against the first end of the spring pin 540. At this time, the spring pin 540 is no longer subjected to the force in the second direction applied to it by the buckle 510, and accordingly, the first magnet 530 no longer moves in the first direction, and the elastic member 550 is no longer subjected to the extrusion force, so the elastic member 550 is reset, that is, it is deformed in the first direction and in the direction pointing to the first magnet 530, so that the first magnet 530 moves in the first direction and away from the elastic member 550. Since the first side of the first magnet 530 is connected to the second end of the spring pin 540, the first magnet 530 causes the spring pin 540 to move in the second direction through the third inclined surface to approach the buckle 510. At this time, the first end of the spring pin 540 is buckled into the buckling portion 411, that is, the first inclined surface of the first end abuts against the fourth inclined surface of the buckling portion 511, and the first end is embedded in the space between the fourth inclined surface of the buckling portion 511 and the wall, and the spring pin 540 is buckled with the buckling portion 511. The buckle 510 is fixed by the spring pin 540 and no longer moves, and the fixing portion 512 abuts against the display device on the side facing the housing 520, so as to achieve the buckling of the limiter 500 and fix the display device.

[0065] During the above-mentioned fastening process, the fastening of the limit member 500 utilizes the external force applied to the buckle 510, and the external force F is parallel to the first direction and points to the display device. After the slide rail of the buckle 510 is engaged with the guide rail of the shell 520, since the buckle 510 is limited by the shell 520 in the second direction and the third direction, the external force in the aforementioned direction can cause the buckle 510 to move, but cannot move along other directions.

[0066] During the buckling process of the stopper 500, the various components cooperate with each other. By applying an external force to the buckle 510, the user can easily move the buckle 510, thereby causing the various components to interact and move, so that the spring pin 540 limits the movement of the buckle 510, and the movement between the buckle 510 and the housing 520 is limited, thereby achieving the fixation of the display device by the stopper 500. The stopper 500 provided in the embodiment of the present application can improve the convenience of fixing the display device, enhance the user's experience, and is conducive to enhancing the stability of the agricultural machinery display device.

[0067] Figure 6 A partial cross-sectional schematic diagram of another limiting member 600 provided in an embodiment of the present application is shown.

[0068] like Figure 6 As shown, the limiting member 600 includes a second magnet 670 for moving the first magnet 630 . Figure 6 The limiting member 600 in the embodiment further includes a buckle 610, a buckling portion 611, a fixing portion 612, a housing 620, a first magnet 630, a spring pin 640 and an elastic member 650. These components can be used together with Figure 3 or Figure 5 The corresponding parts shown in the illustrated stopper 300 or the illustrated stopper 500 are the same.

[0069] See also Figure 6 , the second magnet 670 is disposed outside the stopper 600. Specifically, the second magnet 670 can be disposed in an independent disassembly device, for example, and held by an operator for use, or disposed on a device to which the stopper 600 is attached, and starts to work when the stopper 600 is disassembled. Optionally, the second magnet 670 is made of the same material as the first magnet 630, and the two opposite faces of the two magnets have the same polarity, so that the first magnet 630 moves along the first direction and toward the elastic member 650 due to the property that like charges repel each other.

[0070] The second magnet 670 is arranged on the outside of the limit member 600, so as not to damage the structure of the limit member 600 that is in the engaged state. The first magnet 630 inside the shell 620 can be pushed from the outside, thereby improving the convenience of using the limit member 600. The limit member 600 can be used repeatedly, increasing reusability, and effectively improving the user experience.

[0071] Combine the following Figure 7 The disassembly process of the limiting member 600 is described.

[0072] Figure 7FIG. 1 is a partial cross-sectional schematic diagram of another stopper 700 provided in an embodiment of the present application. The stopper 700 includes a buckle 710, a buckling portion 711, a fixing portion 712, a housing 720, a first magnet 730, a spring pin 740, an elastic member 750, and a second magnet 770. These components can be used together with Figure 6 The corresponding parts shown in the illustrated stop 600 are identical.

[0073] like Figure 7 As shown, when the buckle 710 and the housing 720 are disassembled, the second magnet 770 moves the first magnet 730 along the first direction, and the contact position between the third inclined surface of the first side and the second inclined surface of the spring pin 740 changes. The first magnet 730 moves the spring pin 740 away from the buckle 711 along the second direction through the third inclined surface. As the spring pin 740 moves, the first end of the spring pin 740 leaves the buckle 710, that is, it no longer abuts against the buckle 711 of the buckle 710, and the fixing portion 712 no longer abuts against the display device. When the spring pin 740 completely leaves the buckle 711 and approaches the wall on one side of the display device, the buckle 711 is no longer fixed by the spring pin 740, so that the buckle 710 can move along the slide rail to be disassembled from the housing 720, so as to realize the disassembly of the limiter 700 and release the fixation of the display device.

[0074] Among them, the second magnet 770, based on the principle of like charges repel each other, approaches the stopper 700 along the first direction on the outside, so that the first magnet 730 moves along the first direction and toward the elastic member 750, and the movement direction of the spring pin 740 in the second direction is the direction pointing to the first magnet 730, thereby achieving separation from the buckle portion 711. During the disassembly process of the stopper 700 provided by the present application, through the magnetic properties between the first magnet 730 and the second magnet 770, the user can achieve the movement of the components without damaging the main body of the stopper 700, so as to facilitate disassembly.

[0075] Figure 8 A partial cross-sectional schematic diagram of another limiting member 800 provided in an embodiment of the present application is shown.

[0076] like Figure 8 As shown, the stopper 800 includes a stopper 880, which is disposed in the accommodating cavity of the housing 820 and is disposed in the first direction of the first magnet 830 and away from the elastic member 850. The stopper 880 is used to limit the first magnet 830. The stopper 800 also includes a buckle 810, a buckling portion 811, a fixing portion 812, an elastic pin 840, and a second magnet 870. These components can be used together with Figure 6 or Figure 7 The corresponding parts shown in the illustrated stopper 600 or stopper 700 are the same.

[0077] In the embodiment of the present application, the stopper 880 is disposed on one side of the first magnet 830, and when the first magnet 830 moves along the first direction and away from the display device, the moving distance thereof can be limited, and the fourth inclined surface of the first side of the first magnet 830 can be matched with the second inclined surface of the second end of the elastic pin 840, so as to achieve appropriate interaction to engage or disassemble the stopper 800. The stopper 880 can provide protection for the first magnet 830 and other components, and prevent them from loosening or falling during the movement, which is conducive to improving the stability of the stopper 800 in fixing the display device.

[0078] Optionally, the stop block 880 can be an independent component, which is placed on the side of the first magnet 830 away from the elastic component 850 when the limit member 800 is assembled, and is fixed to the shell 820 by a hot melt process. Alternatively, the stop block 880 can also be integrally formed with the shell 820 of the limit member 800, that is, a protruding portion is provided on the shell to realize the function of the stop block 880.

[0081] In the embodiment of the present application, the limiter 920 is arranged around the edge of the screen of the second display device 910 to form a rounded rectangular structure that wraps the outside of the second display device 910. The limiter 920 includes four buckles 921, which are respectively arranged at the four corners of the second display device 910, corresponding to the corner positions of the screen. As can be seen from the figure, the buckle 921 can be an arc-shaped component to match the shape of the screen at the corner of the display device to improve the stability of the display device. The provision of multiple buckles 921 in the second agricultural machinery 900 can fully provide support for the second display device 910, ensure the stability of the screen of the second agricultural machinery 900, and improve the service life and safety of the equipment.

[0082] In some embodiments, the stopper 920 may further include two buckles 921, which are respectively disposed at two corners in the diagonal direction of the second display device 910.
