[0054] In current vehicles, the instrument cross beam (CCB) of the steering system and the controller bracket of the control system are usually set on the vehicle frame. Among them, the instrument cross beam bracket is a supporting structure for the steering system, instrument panel, air conditioning main unit and other components in the vehicle; the instrument cross beam bracket usually crosses the vehicle body along the width direction of the vehicle body, so the instrument cross beam bracket can also play a role in strengthening the cab. The controller bracket is a component used to fix and support the controller in the vehicle. The controller can be an airbag controller (Airbag Control Unit, ACU) or other controllers; the frame is a frame structure spanning the front and rear axles of the vehicle. The frame usually includes two longitudinal beams and multiple cross beams. The multiple cross beams are connected between the two longitudinal beams at intervals to form the main frame structure of the frame, and a central channel is usually provided near the front wheel of the frame.

[0055] In order to meet the strength requirements of the vehicle frame, the lower part of the instrument crossbeam bracket is usually connected to the central channel, and the controller bracket is usually laid flat on the central channel, that is, the instrument crossbeam bracket and the controller bracket both need to use the central channel as a base. This arrangement can connect the instrument crossbeam bracket and the controller bracket through the central channel, and the force applied to either the instrument crossbeam bracket or the controller bracket can be transmitted to the entire vehicle frame through the central channel, and part of the force applied to the vehicle frame can also be dispersed to the instrument crossbeam bracket and the controller bracket through the central channel.

[0056] However, the current central channel is usually large in size and high in height, which easily takes up a lot of space in the vehicle; at the same time, the central channel is also heavy, which is not conducive to reducing the weight of the frame.

[0057] Based on the above considerations, in order to reduce the weight of the frame and reduce the space occupied while meeting the strength requirements of the instrument cross beam bracket, the controller bracket and the frame, an embodiment of the present application provides a frame, including a first bracket connected to the beam body and a second bracket connected between the two beam bodies, and also includes a connecting member, and the first bracket and the second bracket are connected by the connecting member.

[0058] In such a frame, the beam body can provide support for the first bracket and the second bracket, so that the force on the first bracket and the second bracket can be transmitted to the beam body, and then to the entire frame; the force on the first bracket or the second bracket is transmitted through the connecting piece, so that the first bracket and the second bracket can disperse the force to each other, so that the first bracket and the second bracket can influence each other and further enhance the strength, thereby satisfying the strength requirements of the instrument cross beam bracket, the controller bracket and the frame through the structural setting of the beam body and the connecting piece; because the connecting piece connects the first bracket, the second bracket and the two beam bodies to each other, these structures can disperse the force to each other and thus satisfy the strength requirements of the instrument cross beam bracket, the controller bracket and the frame, so the first bracket and the second bracket do not need to be arranged on the central channel, so that there is no need to set a central channel on the frame, thereby reducing the weight of the frame and reducing the space occupied by the central channel.

[0059] The vehicle frame disclosed in the embodiment of the present application can be used for various vehicles. The vehicle can be a fuel vehicle, a gas vehicle or a new energy vehicle, and the new energy vehicle can be a pure electric vehicle, a hybrid vehicle or an extended-range vehicle, etc. The vehicle can be a large vehicle, a small vehicle, a special vehicle, etc.; for example, according to the vehicle model, the vehicle can be a truck model, such as a heavy truck, the vehicle can also be a sedan model, an off-road vehicle, a multi-purpose vehicle (MPV) model or other models.

[0060] First, refer to Figure 1Some embodiments of the present application provide a vehicle frame 100, including a beam body 10, a first bracket 20, a second bracket 30 and a connector 40. There are at least two beam bodies 10 and they are spaced apart along the length direction of the vehicle frame 100; the first bracket 20 is provided on any beam body 10 and is used to install the steering system of the vehicle; the second bracket 30 is provided between the two beam bodies 10 and is used to install the control system of the vehicle; one end of the connector 40 is connected to the first bracket 20, and the other end is connected to the second bracket 30.

[0061] Figure 1 , the direction indicated by the X-axis is the width direction of the frame 100 , and the direction indicated by the Y-axis is the length direction of the frame 100 .

[0062] The beam body 10 refers to the beam structure in the frame 100. The beam body 10 is used to bear loads and forces, and to provide a fixed foundation for structures such as the first bracket 20 and the second bracket 30. The length direction of the beam body 10 can extend parallel to the width direction X of the frame 100, or can be inclined relative to the width direction X of the frame 100. The shape of the beam body 10 can be a rectangular parallelepiped, a polygonal column or other regular shapes, and the shape of the beam body 10 can be an irregular shape. The material of the beam body 10 can include metal, inorganic fiber or other materials.

[0063] There are at least two beam bodies 10 and they are spaced apart along the length direction Y of the frame 100, that is, there is a space between the two beam bodies 10 to accommodate and install other structures of the vehicle; it can be understood that the frame 100 may include other beam structures in addition to the beam bodies 10.

[0064] For example, since the frame 100 generally includes two longitudinal beams and a plurality of cross beams connected between the two longitudinal beams, the beam body 10 can be two adjacent cross beams in the frame 100 close to the front wheels of the vehicle. In this case, the frame 100 also includes other cross beams, longitudinal beams or other beam structures different from the beam body 10.

[0065] The first bracket 20 refers to a structure on the vehicle frame 100 for installing the steering system, and the instrument beam bracket of the steering system can be installed on the first bracket 20; the first bracket 20 can be a frame structure, or a plate structure or a structure of other shapes; the material of the first bracket 20 can include metal, inorganic fiber or other materials.

[0066] The first bracket 20 can be arranged on any beam body 10. Since the two beam bodies 10 are arranged along the length direction Y of the frame 100, the first bracket 20 can be arranged on the beam body 10 close to the instrument panel, and the first bracket 20 can also be arranged on the beam body 10 close to the rear vehicle body; the first bracket 20 can be fixedly connected to the beam body 10 by welding, bonding, etc., and can also be detachably connected to the beam body 10 by screwing, clamping, etc.

[0067] The second bracket 30 refers to a structure on the vehicle frame 100 for installing a control system. The airbag controller can be installed on the second bracket 30. The second bracket 30 can also be used to install other controllers, such as an air-conditioning controller, an audio controller, etc.; the second bracket 30 can be a frame structure, or a plate structure or a structure of other shapes; the material of the second bracket 30 can include metal, inorganic fiber or other materials.

[0068] The second bracket 30 is arranged between the two beam bodies 10. Since the second bracket 30 is used for installing the control system, this arrangement enables the two beam bodies 10 to provide a certain degree of protection for the second bracket 30. The second bracket 30 can be connected to both beam bodies 10 or only to one beam body 10. The second bracket 30 can also be connected to other structural parts of the frame 100 (such as the floor 200) instead of being connected to the beam body 10.

[0069] The connector 40 refers to a structure in the frame 100 for connecting the first bracket 20 and the second bracket 30. The connector 40 may be a frame structure, or a plate structure, a strip structure, or a structure of other shapes; the material of the connector 40 may include metal, inorganic fiber, or other materials.

[0070] One end of the connecting member 40 is connected to the first bracket 20. The connecting member 40 can be fixedly connected to the first bracket 20 by welding, bonding, etc., or it can be detachably connected to the first bracket 20 by screwing, clamping, etc.; the other end of the connecting member 40 is connected to the second bracket 30. The connecting member 40 can be fixedly connected to the second bracket 30 by welding, bonding, etc., or it can be detachably connected to the second bracket 30 by screwing, clamping, etc.; it can be understood that the connecting member 40 can also be connected to the beam body 10.

[0071] When the first bracket 20 is hit by an external force, part of the external force can be transmitted to the second bracket 30 via the connecting member 40, and another part of the external force can also be transmitted to the beam body 10, so that the force exerted on the first bracket 20 can be shared by the connecting member 40, the second bracket 30 and the beam body 10, thereby achieving the effect of improving the strength of the first bracket 20.

[0072] When the second bracket 30 is hit by an external force, part of the external force can be transmitted to the first bracket 20 via the connecting member 40, and then transmitted to the beam body 10 via the first bracket 20, so that the force exerted on the second bracket 30 can be shared by the connecting member 40, the second bracket 30 and the beam body 10, thereby achieving the effect of improving the strength of the second bracket 30.

[0073] In this embodiment, the first bracket 20 is arranged on the beam body 10, and the beam body 10 provides support for the first bracket 20, so that the force on the first bracket 20 can be transmitted to the beam body 10, and then transmitted to the entire frame 100; the first bracket 20 and the second bracket 30 are connected by the connecting member 40, so that the force on the first bracket 20 or the second bracket 30 is transmitted through the connecting member 40, so that the first bracket 20 and the second bracket 30 can disperse the force to each other, so that the first bracket 20 and the second bracket 30 can affect each other and strengthen the strength, and then the structural setting of the beam body 10 and the connecting member 40 satisfies the instrument cross beam bracket, the controller bracket and The strength requirement of the frame 100; on the premise of meeting the strength requirements of the instrument cross beam bracket, the controller bracket and the frame 100, the setting of the connecting piece 40 enables the first bracket 20, the second bracket 30 and the beam body 10 to be interconnected to form a whole and to disperse the force to each other, thereby meeting the strength requirements of the instrument cross beam bracket, the controller bracket and the frame 100. Therefore, the first bracket 20 and the second bracket 30 do not need to be arranged on the central channel, and the central channel does not need to be arranged on the frame 100, thereby reducing the weight of the frame 100, reducing the space occupied by the central channel on the frame 100, and also reducing the space occupied by the frame 100.

[0074] refer to Figures 2 to 4 In some embodiments, the connecting member 40 includes a first portion 41 , a second portion 42 , and a third portion 43 that are connected in sequence, the first portion 41 is connected to the first bracket 20 , and the third portion 43 is connected to the second bracket 30 .

[0075] The first part 41, the second part 42 and the third part 43 are all partial structures of the connecting member 40, and the first part 41, the second part 42 and the third part 43 are connected in sequence, that is, one end of the first part 41 is connected to the second part 42, and the other end of the second part 42 is connected to the third part 43; the first part 41, the second part 42 and the third part 43 can be connected by welding, bonding or other methods, and can also be connected by an integrated molding process; for example, the first part 41, the second part 42 and the third part 43 are made of an integral molding.

[0076] The first part 41 is used to connect to the first bracket 20, and the third part 43 is used to connect to the second bracket 30; the first part 41 can be fixedly connected to the first bracket 20 by welding, bonding, etc., and the first part 41 can also be detachably connected to the first bracket 20 by screwing, snapping, etc.; the third part 43 can be fixedly connected to the second bracket 30 by welding, bonding, etc., and the third part 43 can also be detachably connected to the second bracket 30 by screwing, snapping, etc.

[0077] The second portion 42 is used to transfer the force on the first portion 41 or the third portion 43. Specifically, part of the force received by the first bracket 20 can be transferred to the second bracket 30 via the first portion 41, the second portion 42 and the third portion 43, so that the second bracket 30 can bear part of the load of the first bracket 20, thereby achieving the effect of increasing the strength of the first bracket 20; similarly, part of the force received by the second bracket 30 can be transferred to the first bracket 20 via the third portion 43, the second portion 42 and the first portion 41, so that the first bracket 20 can bear part of the load of the second bracket 30, thereby achieving the effect of increasing the strength of the second bracket 30.

[0078] In this embodiment, the first portion 41 and the third portion 43 are connected to the first bracket 20 and the second bracket 30 at both ends, and the first portion 41 and the third portion 43 are connected through the second portion 42, so that the force on the first bracket 20 and the second bracket 30 is transmitted through the second portion 42, so that the first bracket 20 and the second bracket 30 can disperse the force on each other and play a role of reinforcing each other.

[0079] refer to Figures 2 to 4 In some embodiments, a first bending portion 44 is provided on the second portion 42 , and the first bending portion 44 is bent relative to the second portion 42 and is arranged at an angle to the second portion 42 .

[0080] The first bending portion 44 can be bent relative to the second portion 42 and form an angle at the position where the first bending portion 44 and the second portion 42 are connected; for example, when the second portion 42 and the first bending portion 44 are both plate structures, the bending of the first bending portion 44 relative to the second portion 42 means that the two are not coplanar and form an angle; for another example, when the second portion 42 and the first bending portion 44 are both rods, the bending of the first bending portion 44 relative to the second portion 42 means that the extension directions of the two are not parallel.

[0081] The angle formed between the first bending portion 44 and the second portion 42 may be an acute angle or an obtuse angle, and the first bending portion 44 may also be perpendicular to the second portion 42 .

[0082] The first bending portion 44 can be fixedly connected to the second portion 42 by welding, bonding, etc., and the first bending portion 44 can also be integrally formed with the second portion 42; for example, the first bending portion 44 is integrally formed with the second portion 42, and the first bending portion 44 is formed by a stamping process.

[0083] The connection position between the first bending portion 44 and the second portion 42 may form an edge (i.e. a sharp corner) or an arcuate edge (i.e. a rounded corner); for example, the connection position between the first bending portion 44 and the second portion 42 forms an arcuate edge.

[0084] Since the two ends of the second portion 42 are connected to the first portion 41 and the third portion 43 respectively, the first bending portion 44 is provided on the side of the second portion 42 that is away from the first portion 41, that is, the first bending portion 44 is provided on the side of the second portion 42 that is adjacent to the third portion 43. The first bending portion 44 is provided on at least one side of the second portion 42, that is, the first bending portion 44 may be provided on only one side of the second portion 42, or may be provided on both opposite sides of the second portion 42.

[0085] Because the first bent portion 44 is arranged at an angle relative to the second portion 42, in the cross section along the width direction of the second portion 42, the first bent portion 44 can increase the thickness of the connecting piece 40 at the second portion 42, thereby enhancing the strength of the second portion 42 and increasing the bending and torsional strength of the second portion 42; at the same time, the setting of the first bent portion 44 can also reduce the stress concentration phenomenon at the edge of the second portion 42, thereby increasing the service life of the connecting piece 40.

[0086] In this embodiment, a first bending portion 44 is provided on the second portion 42, and the first bending portion 44 is provided at an angle to the second portion 42. The provision of the first bending portion 44 can increase the cross-sectional thickness of the second portion 42, improve the rigidity and bearing capacity of the second portion 42, and at the same time change the stress distribution and reduce stress concentration, thereby enhancing the strength of the second portion 42 through the first bending portion 44 and playing a role in strengthening the overall strength of the connecting member 40.

[0087] In some embodiments, the first portion 41 is welded to the first bracket 20 ; and / or the third portion 43 is welded to the second bracket 30 .

[0088] The first part 41 is welded to the first bracket 20, and the first part 41 can be welded to the first bracket 20 by fusion welding, pressure welding or brazing. The third part 43 is welded to the second bracket 30, and the third part 43 can be welded to the second bracket 30 by fusion welding, pressure welding or brazing.

[0089] The first part 41 and the third part 43 can be respectively connected to the first bracket 20 and the second bracket 30 by welding, or only the first part 41 can be welded to the first bracket 20, or only the third part 43 can be welded to the second bracket 30; for example, when the first part 41 is welded to the first bracket 20, the third part 43 can be welded to the second bracket 30, and the third part 43 can also be connected to the second bracket 30 by other means; when the third part 43 is welded to the second bracket 30, the first part 41 can be welded to the first bracket 20, and the first part 41 can also be connected to the first bracket 20 by other means.

[0090] The welding process has strong connection stability and is also convenient for force transmission; taking the welding of the first part 41 to the first bracket 20 as an example, the welding process can make the first part 41 and the first bracket 20 fuse with each other at their connection position to form a connection structure, which can fill the tiny gaps and gaps between the first part 41 and the first bracket 20 during the formation process to form a continuous connection structure, so that the connection structure can better transmit force and have strong stability.

[0091] In this embodiment, the first part 41 and the third part 43 are fixed by welding so that the first part 41 and the third part 43 can be more stably connected to the corresponding first bracket 20 and the second bracket 30, thereby further improving the overall strength and stability of the first bracket 20 and the second bracket 30.

[0092] refer to Figure 2 , Figure 3 In some embodiments, the second portion 42 is connected to the beam body 10 .

[0093] Because the first bracket 20 is arranged on the beam body 10, and the second bracket 30 is arranged between the two beam bodies 10, the second part 42 can be connected to the same beam body 10 as the first bracket 20; the second part 42 can be fixedly connected to the corresponding beam body 10 by welding, bonding, etc., and the second part 42 can also be detachably connected to the corresponding beam body 10 by screwing, clamping, etc.

[0094] When the second portion 42 is connected to the beam body 10, during the process of the second portion 42 transmitting the force between the first portion 41 and the third portion 43, part of the force on the second portion 42 can be transmitted to the beam body 10. At this time, the beam body 10 can also play a role in sharing the load on the first bracket 20 and the second bracket 30, so that the load on the first bracket 20 and the second bracket 30 can be dispersed to other positions of the frame 100 through the connecting member 40 and the beam body 10, thereby better strengthening the strength and bearing capacity of the first bracket 20 and the second bracket 30, and improving the integrity of the frame 100; at the same time, the strength of the second portion 42 can be increased, thereby reducing the deformation, breakage, etc. that may occur in the second portion 42.

[0095] In this embodiment, the second part 42 is connected to the beam body 10 so that the force on the first bracket 20 or the second bracket 30 can also be transmitted to the beam body 10 through the second part 42, and the beam body 10 can also disperse the force on the first bracket 20 or the second bracket 30, so that the first bracket 20, the second bracket 30 and the beam body 10 can be better connected as a whole, thereby further improving the overall strength of the first bracket 20 and the second bracket 30.

[0096] refer to Figure 2 , Figure 3In some embodiments, the first bracket 20 includes two fixing members 21, which are disposed on the beam body 10 and connected to the connecting member 40; along the thickness direction of the connecting member 40, the two fixing members 21 are respectively disposed on opposite sides of the connecting member 40.

[0097] The fixing member 21 can be a long strip or plate-like structure, or a block structure or a structure of other shapes; the fixing member 21 can be fixedly connected to the connecting member 40 by welding, bonding or other means, or can be detachably connected to the connecting member 40 by screwing, snapping or other means; the material of the fixing member 21 can include metal, inorganic fiber or other materials.

[0098] Since the first bracket 20 is disposed on the beam body 10, the fixing member 21 is also disposed on the beam body 10; the fixing member 21 can be fixedly connected to the beam body 10 by welding, bonding or other means, and can also be detachably connected to the beam body 10 by screwing, clamping or other means.

[0099] There are two fixing members 21, and the two fixing members 21 are arranged on opposite sides of the connecting member 40. At this time, the two fixing members 21 can clamp the connecting member 40 to better fix the connecting member 40 and reduce the deformation or displacement of the connecting member 40; at the same time, the contact area between the first bracket 20 and the connecting member 40 can be increased to reduce stress concentration and improve the stability of the connection between the first bracket 20 and the connecting member 40.

[0100] The thickness direction of the connecting member 40 may be parallel to the width direction X or the length direction Y of the frame 100 , or may be arranged at an angle to the width direction X of the frame 100 ; for example, the thickness direction of the connecting member 40 is parallel to the width direction X of the frame 100 .

[0101] The two fixing members 21 are arranged on opposite sides of the connecting member 40 along the thickness direction of the connecting member 40. This arrangement can further increase the contact area between the fixing members 21 and the connecting member 40, thereby better reducing stress concentration and better improving the stability of the connection.

[0102] In this embodiment, the connecting member 40 is clamped by two fixing members 21 so that the connecting member 40 can be more stably connected to the first bracket 20, while also reducing the deformation of the connecting member 40 during force transmission, thereby improving the strength of the connection between the connecting member 40 and the first bracket 20.

[0103] refer to Figure 2 , Figure 3 , Figure 5 In some embodiments, the fixing member 21 includes a main body 211 and a second bending portion 212 disposed on the main body 211 . The second bending portion 212 is bent relative to the main body 211 and is disposed at an angle to the main body 211 .

[0104] The main body 211 refers to the structure in the fixing part 21 that is mainly used to connect with the connecting part 40 and the beam body 10. The main body 211 can be connected to the connecting part 40, and the main body 211 can also be connected to the beam body 10; the main body 211 can be fixedly connected to the connecting part 40 by welding, bonding or other methods, and can also be detachably connected to the connecting part 40 by screwing, clamping or other methods; the material of the main body 211 may include metal, inorganic fiber or other materials.

[0105] The second bending portion 212 can be bent relative to the main body portion 211 and form an angle at the position where the second bending portion 212 and the main body portion 211 are connected; for example, when the main body portion 211 and the second bending portion 212 are both plate structures, the bending of the second bending portion 212 relative to the main body portion 211 means that the two are not coplanar and form an angle; for another example, when the main body portion 211 and the second bending portion 212 are both rods, the bending of the second bending portion 212 relative to the main body portion 211 means that the extension directions of the two are not parallel.

[0106] The angle formed between the second bending portion 212 and the main body portion 211 can be an acute angle or an obtuse angle, and the second bending portion 212 can also be perpendicular to the main body portion 211; the second bending portion 212 can be formed on one side of the main body portion 211, or the second bending portion 212 can be set on both opposite sides of the main body portion 211.

[0107] The second bending portion 212 can be fixedly connected to the main body 211 by welding, bonding, etc., and the second bending portion 212 can also be integrally formed with the main body 211; for example, the second bending portion 212 is integrally formed with the main body 211, and the second bending portion 212 is formed by a stamping process.

[0108] The connection position between the second bending portion 212 and the main body 211 can form an edge (i.e. a sharp corner) or an arc-shaped edge (i.e. a rounded corner); for example, the connection position between the second bending portion 212 and the main body 211 forms an arc-shaped edge.

[0109] Because the second bending portion 212 is arranged at an angle relative to the main body portion 211, in the cross section along the width direction of the main body portion 211, the second bending portion 212 can increase the thickness of the fixing member 21, thereby increasing the strength of the fixing member 21, and can increase the bending and torsional strength of the main body portion 211; at the same time, the setting of the second bending portion 212 can also reduce the stress concentration phenomenon at the edge of the main body portion 211, thereby increasing the service life of the connecting member 40.

[0110] In this embodiment, a second bending portion 212 is provided on the main body portion 211, and the second bending portion 212 is provided at an angle to the main body portion 211. The provision of the second bending portion 212 can increase the cross-sectional thickness of the main body portion 211, improve the rigidity and bearing capacity of the main body portion 211, and at the same time can change the stress distribution and reduce stress concentration, thereby enhancing the strength of the main body portion 211 through the second bending portion 212, and playing a role in strengthening the overall strength of the fixing member 21.

[0111] refer to Figure 2 , Figure 3 , Figure 5 In some embodiments, the main body 211 of the fixing member 21 includes a fourth portion 2111 and a fifth portion 2112 connected to each other, the fourth portion 2111 is connected to the first bracket 20, and the fifth portion 2112 is connected to the beam body 10; the fourth portion 2111 and the fifth portion 2112 are arranged at an angle.

[0112] The fourth part 2111 and the fifth part 2112 are both partial structures of the fixing part 21, and the fourth part 2111 and the fifth part 2112 are connected to each other, that is, one end of the fourth part 2111 is connected to one end of the fifth part 2112; the fourth part 2111 and the fifth part 2112 can be connected by welding, bonding or other methods, and can also be connected by an integral molding process; for example, the fourth part 2111 and the fifth part 2112 are made of an integral molding.

[0113] The fourth portion 2111 and the fifth portion 2112 are both parts of the main body 211 . The second bending portion 212 may be formed on only one of the fourth portion 2111 or the fifth portion 2112 , or may be formed on both the fourth portion 2111 and the fifth portion 2112 .

[0114] The fourth part 2111 is connected to the connecting member 40, and the fifth part 2112 is connected to the beam body 10; the fourth part 2111 can be fixedly connected to the connecting member 40 by welding, bonding, etc., and the fourth part 2111 can also be detachably connected to the connecting member 40 by screwing, clamping, etc.; the fifth part 2112 can be fixedly connected to the beam body 10 by welding, bonding, etc., and the fifth part 2112 can also be detachably connected to the beam body 10 by screwing, clamping, etc.

[0115] The connection position between the fourth portion 2111 and the fifth portion 2112 may form an edge (i.e., a sharp corner) or an arcuate edge (i.e., a rounded corner); for example, the connection position between the fourth portion 2111 and the fifth portion 2112 forms an arcuate edge.

[0116] In this embodiment, the fixing member 21 is connected to the connecting member 40 and the beam body 10 respectively through the fourth part 2111 and the fifth part 2112, so that the fixing member 21 can better fix the connecting member 40 and enable the force on the first bracket 20 to be transmitted to the beam body 10, thereby better strengthening the strength of the first bracket 20; at the same time, the fourth part 2111 and the fifth part 2112 are arranged at an angle, which can also increase the cross-sectional thickness of the fixing member 21, improve the rigidity and bearing capacity of the second part 42, and at the same time change the stress distribution and reduce stress concentration, thereby further improving the strength of the connection between the first bracket 20 and the beam body 10.

[0117] refer to Figure 2 , Figure 3 , Figure 5 In some embodiments, a first through hole 213 is formed on the fixing member 21, and a second through hole 45 is formed on the connecting member 40. The first through hole 213 is opposite to and connected to the second through hole 45.

[0118] The first through hole 213 is a hole structure opened on the fixing member 21, and the first through hole 213 can penetrate the fixing member 21; the first through hole 213 can be a straight hole, or a stepped hole or a hole of other shapes; the number of the first through holes 213 can also be one, or two or more; for example, the first through hole 213 can be formed on the fourth part 2111.

[0119] The second through hole 45 is a hole structure opened on the connecting member 40, and the second through hole 45 can penetrate the connecting member 40; the second through hole 45 can be a straight hole, or a stepped hole or a hole of other shapes; the number of the second through holes 45 can be one, or two or more; for example, the second through hole 45 can be formed on the first part 41.

[0120] The first through hole 213 is opposite to and connected to the second through hole 45, so that the steering system or other structure installed on the first bracket 20 can be installed on the first bracket 20 through fasteners. The fasteners can pass through the first through hole 213 and the second through hole 45, so that the fasteners can directly transfer the force they bear to the connecting member 40 and the first bracket 20, thereby better increasing the stability of the steering system or other structures connected to the frame 100.

[0121] Taking the example of the instrument beam bracket of the steering system being installed on the first bracket 20 by bolts, the bolts can pass through the instrument beam bracket and through the first through hole 213 and the second through hole 45, and then be fastened by nuts to install the instrument beam bracket on the first bracket 20. At this time, the bolts can transfer part of the force they bear to the first bracket 20, and the bolts can also transfer part of the force they bear to the connecting member 40, and the part of the force carried by the first bracket 20 can also be transferred to the beam body 10 and the connecting member 40 respectively.

[0122] Since the first through hole 213 and the second through hole 45 are used for fasteners to pass through, the inner diameters of the first through hole 213 and the second through hole 45 can be the same or different, but the inner diameters of the first through hole 213 and the second through hole 45 should be greater than or equal to the outer diameters of the corresponding fasteners.

[0123] In this embodiment, a first through hole 213 and a second through hole 45 are respectively provided on the fixing member 21 and the connecting member 40 so that bolts or other fasteners can pass through the first through hole 213 and the second through hole 45, thereby facilitating the installation of the instrument cross beam bracket or other structure on the first bracket 20.

[0124] refer to Figure 2 , Figure 6 In some embodiments, the second bracket 30 includes a base 31 and a mounting portion 32 protruding from the base 31 , two ends of the base 31 are respectively connected to the two beam bodies 10 , and the connecting member 40 is connected to the base 31 .

[0125] The base 31 refers to a partial structure of the second bracket 30. The base 31 is used to provide a fixed foundation for the mounting portion 32 or other structures. The base 31 is also used to bear the force transmitted by structures such as the control system and the first bracket 20. The base 31 can be a block structure or a door-shaped structure formed by stamping a plate. The material of the base 31 can include metal, inorganic fiber or other materials.

[0126] The two ends of the base 31 are respectively connected to the two beams 10 so that part of the force borne on the base 31 can be transmitted to the two beams 10; the base 31 can also transmit the force borne on the two beams 10. At this time, the force borne on the beam 10 can be transmitted through the base 31 in addition to being transmitted through the longitudinal beam of the frame 100, so that the base 31 can enhance the strength and bearing capacity of the second bracket 30 and the two beams 10.

[0127] The base 31 can be fixedly connected to the beam body 10 by welding, bonding, etc., or can be detachably connected to the beam body 10 by screwing, clamping, etc.

[0128] One end of the connecting member 40 connected to the second bracket 30 is connected to the base 31. For example, the one end of the connecting member 40 connected to the second bracket 30 can be connected to the middle of the base 31, so that the base 31 can also bear the force transmitted by the connecting member 40, and the base 31 can also transmit the force it bears to the first bracket 20, thereby enhancing the strength and bearing capacity of the first bracket 20 and the second bracket 30.

[0129] The mounting portion 32 refers to a structure in the second bracket 30 that protrudes from the base 31. The mounting portion 32 is used to provide a mounting position for the control system or other structures to facilitate the installation of the control system or other structures on the second bracket 30. At the same time, the mounting portion 32 can also provide support for the control system or other structures to improve the stability of the installation on the second bracket 30.

[0130] The number of mounting parts 32 may be one, or two or more; for example, the number of mounting parts 32 is three to support different positions of the control system or other structures, thereby better improving the installation stability of the control system or other structures.

[0131] The mounting portion 32 may be an independent structure and connected to the base 31. In this case, the mounting portion 32 may be fixedly connected to the base 31 by welding, bonding, etc., or may be fixedly connected to the base 31 by screwing, snapping, etc.; the mounting portion 32 may also be formed integrally with the base 31 as a part of the base 31.

[0132] According to the formation method of the mounting portion 32 , the material of the mounting portion 32 may be the same as or different from the material of the base 31 ; the material of the mounting portion 32 may include metal, inorganic fiber or other materials.

[0133] When the second bracket 30 is hit by an external force, the second bracket 30 can transfer part of the external force to the two beam bodies 10 through the base 31, and can also transfer another part of the external force to the first bracket 20 through the connecting member 40 through the base 31, so that the force exerted on the second bracket 30 can be shared by the connecting member 40, the first bracket 20 and the beam body 10, thereby achieving the effect of improving the strength of the second bracket 30.

[0134] When either of the two beam bodies 10 is hit by an external force, both beam bodies 10 can transfer part of the external force to the other beam body 10 through the base 31, and transfer the external force to the first bracket 20, so that the force exerted on the beam body 10 can be shared by the first bracket 20, the second bracket 30 and the other beam body 10, thereby achieving the effect of improving the strength of the beam body 10.

[0135] In this embodiment, the two ends of the base 31 are connected to the two beams 10 so that the two beams 10 and the second bracket 30 can be connected as a whole, thereby improving the overall strength of the frame 100; a mounting portion 32 protruding from the base 31 is provided to facilitate the installation of a controller bracket or other structures on the second bracket 30.

[0138] Since there are two first brackets 20, there are also two connecting members 40, and the two connecting members 40 correspond to the two first brackets 20 respectively. Specifically, one end of the connecting member 40 is connected to the corresponding first bracket 20, and the other end of the connecting member 40 is connected to the second bracket 30, so that the two first brackets 20 can transfer part of the force they bear to the second bracket 30 through the connecting member 40.

[0139] In this embodiment, there are two first brackets 20 so that the instrument cross beam bracket or other structures can be more stably connected to the frame 100 through the first brackets 20, thereby better improving the stability and overall strength of the frame 100.

[0140] In some embodiments, the workshop includes two beam bodies 10 , two first brackets 20 , two second connecting members 40 and one second bracket 30 .

[0148] The two beams 10 and the second bracket 30 of the frame 100 are connected to the floor 200. This arrangement can increase the strength of the floor 200, so that when the floor 200 is subjected to external force, it can transfer part of the external force to the beam 10 and the second bracket 30, thereby reducing the deformation of the floor 200 and increasing the strength of the floor 200; at the same time, it can also enable the beam 10 and the second bracket 30 to transfer part of the external force to the floor 200 when subjected to external force, and also transfer part of the external force received to other positions or other structures of the frame 100 through the floor 200, thereby improving the strength and integrity of the frame 100.
