Description

Technical Field

[0001] This application belongs to the field of vehicle manufacturing technology, and in particular relates to an upper structure support lug structure. Background Technology

[0002] In vehicle structures, the tilting bracket structure is used to support the superstructure equipment on the vehicle chassis, serving both a supporting function and as a foundation for tilting. Tilting bracket structures mostly adopt a combination of cantilever brackets and a crossbeam body, forming a bracket-crossbeam structure. The frame crossbeam connects to the left and right longitudinal beams of the frame, while the cantilever bracket connects to the hydraulic cylinder supporting the tilting mechanism. Currently, tilting bracket structures are generally manufactured using a large, integrally welded bracket-crossbeam structure. The crossbeam body is a large, box-shaped welded crossbeam, ultimately welded to the rear of the frame longitudinal beams, connecting the left and right frame longitudinal beams. The cantilever bracket is also a box-shaped welded structure, with its rear portion welded to the frame crossbeam body. This type of tilting bracket structure requires high welding quality and minimal structural deformation after forming.

[0003] For the chassis of some heavy or super heavy vehicles, the load-bearing capacity and structural strength requirements of the tilting lug structure are higher. Because the chassis structure of these vehicles is compact, the local space is limited, and lightweighting is required, the design of the tilting lug structure is subject to higher requirements. However, the existing lug beam structure of the tilting lug structure cannot meet the load-bearing capacity and structural strength requirements. Summary of the Invention

[0004] This application aims to at least partially solve the technical problem that existing superstructure support structures are unsuitable for heavy or super-heavy vehicle chassis. To this end, this application provides a superstructure support structure that can simultaneously connect the superstructure equipment and the frame longitudinal beams, improving load-bearing capacity and structural strength. It can withstand the forces exerted by the superstructure equipment on the frame, meeting the requirements of frames with high load-bearing capacity, and is suitable for heavy or super-heavy vehicle chassis.

[0005] In a first aspect, this application provides an upper mounting bracket structure, comprising:

[0006] The bracket includes a bracket crossbeam and multiple bracket longitudinal beams. The multiple bracket longitudinal beams are connected to the bracket crossbeam. Adjacent bracket longitudinal beams are spaced apart. The bracket longitudinal beams are fixed to the vehicle frame longitudinal beams.

[0007] A bracket panel, which is fixedly connected to at least one bracket longitudinal beam;

[0008] The lug mount is installed on the bracket panel and has bearing connectors for connecting and rotating the upper equipment.

[0009] Conventional upper structure brackets use a bracket crossbeam structure. Due to the length limitation of the crossbeam, a large bracket interface size cannot be guaranteed, resulting in limited load-bearing capacity. Furthermore, installing such bracket structures requires high tolerance precision; otherwise, unstable connections or failures may occur. This application, however, places the upper structure bracket on the vehicle frame longitudinal beam. A bracket system composed of a crossbeam and longitudinal beams provides a stable foundation for the bracket seat. A bracket panel provides a platform for installation and fixation of the bracket seat. The bracket seat provides connection support for the upper structure equipment and serves as a base for tilting, facilitating the installation and tilting of the upper structure equipment. The upper structure bracket structure can simultaneously connect the upper structure equipment and the vehicle frame longitudinal beam. Because the bracket is connected to the vehicle frame longitudinal beam, there is no length limitation associated with installation on a crossbeam, allowing for a larger bracket seat size. This results in a larger contact area for the bracket seat, which helps to... This invention improves the stability and structural strength of the connection while reducing the precision requirements, avoiding instability in the connection between the support lug and the superstructure. The force on the support lug can be directly transferred to the longitudinal beam of the frame, thereby improving the overall structural load-bearing capacity. Since the bracket also adopts a longitudinal and transverse combined structure, it serves as a support for the support lug and has strong structural strength, better torsional and bending resistance, and can withstand the force exerted on the frame by the superstructure. This application changes the conventional support lug structure and setting method to meet the frame with high load-bearing capacity requirements and is suitable for vehicles with high load-bearing requirements.

[0010] In an optional embodiment, the lugs and the longitudinal beams of the support are respectively connected to both sides of the support panel. The lugs correspond to the longitudinal beams of the support, and the longitudinal beams of the support indirectly bear the load on the lugs in the vertical direction.

[0011] In an optional embodiment, the support longitudinal beam includes longitudinal beam side plates, a top plate, a cover plate, a bottom plate, and an end plate. One end of the longitudinal beam side plate is wedge-shaped, and multiple longitudinal beam side plates are arranged at intervals. The periphery of all longitudinal beam side plates is connected to the top plate, cover plate, bottom plate, and end plate, respectively, and the connection forms a cavity structure. The bottom plate is connected to the longitudinal beam of the frame along the arrangement direction of the frame longitudinal beam.

[0012] In an optional embodiment, the longitudinal beam of the support also includes longitudinal beam expansion plates, which are spaced apart on the side plates of the longitudinal beam, and the two ends of the longitudinal beam expansion plates are respectively connected to the top plate and the bottom plate.

[0013] In an optional embodiment, the support longitudinal beam also includes multiple vertical plates, which are connected between the top plate and the bottom plate.

[0014] In an optional embodiment, the longitudinal beam side plate is provided with multiple clearance holes, and a liner is also provided at the clearance holes. The liner covers all longitudinal beam side plates at the clearance holes and the liner closes the cavity structure. A pad is also provided at the end of some clearance holes.

[0015] In an optional embodiment, a closed frame structure is further provided between the support panel and the frame longitudinal beam. The closed frame structure is connected to the side of the support longitudinal beam and is formed by at least two of the following connections: plates, grooves, or ribs.

[0016] In an optional embodiment, the longitudinal beam of the support is further provided with reinforcing members, which include plates, grooves, or ribs.

[0017] In an optional embodiment, the support ear includes a support ear, the support ear includes multiple ear sides, a bearing connector is connected to the ear sides, and the support surface of the ear sides for supporting the upper equipment is set as an inclined surface, so that the ear sides form a wedge-shaped structure.

[0018] Secondly, this application provides a vehicle including a body, a frame, and the aforementioned upper structure support lugs. The frame is mounted on the body and includes frame longitudinal beams and frame crossbeams. The support longitudinal beams are mounted on the frame longitudinal beams.

[0019] The beneficial effects of this application are:

[0020] 1. This application places the upper structure support lugs on the longitudinal beams of the vehicle frame. The bracket, composed of the bracket crossbeams and the bracket longitudinal beams, provides a stable foundation for the lugs. The bracket panel provides a platform for installation and fixation of the lugs. The lugs provide connection support for the upper structure equipment and serve as a base for tilting, facilitating the installation and tilting of the upper structure equipment. The upper structure support lugs can simultaneously connect the upper structure equipment and the longitudinal beams of the vehicle frame. Because the bracket is connected to the longitudinal beams of the vehicle frame, there is no length limitation compared to installation on the crossbeams, allowing for larger lug sizes. This results in a larger contact area for the lugs, which helps to... This invention improves the stability and structural strength of the connection while reducing the precision requirements, avoiding instability in the connection between the support lug and the superstructure. The force on the support lug can be directly transferred to the longitudinal beam of the frame, thereby improving the overall structural load-bearing capacity. Since the bracket also adopts a longitudinal and transverse combined structure, it serves as a support for the support lug and has strong structural strength, better torsional and bending resistance, and can withstand the force exerted on the frame by the superstructure. This application changes the conventional support lug structure and setting method to meet the frame with high load-bearing capacity requirements and is suitable for vehicles with high load-bearing requirements.

[0021] 2. The vehicle of this application adopts a superstructure support ear structure, which changes the original support ear crossbeam structure. By installing the bracket longitudinal beam on the frame longitudinal beam, the load-bearing capacity of the superstructure support ear structure is indirectly improved through the load-bearing capacity of the frame longitudinal beam. As a result, the superstructure support ear structure can provide better torsional and bending resistance, and the vehicle can carry heavier superstructure equipment, thus making it suitable for heavy or super heavy vehicles.

[0038] This application is described below with reference to the accompanying drawings and specific embodiments:

[0039] Please refer to Figure 1 This application provides an upper structure bracket 100, which includes a bracket 110, a bracket panel 120, and a bracket seat 130. The bracket 110 and bracket panel 120 are welded from sheet metal. The bracket 110 is a joint structure of a bracket crossbeam 111 and a bracket longitudinal beam 112, and is fixed to the frame longitudinal beam 220. The bracket 110 provides a stable foundation for the bracket seat 130. The bracket panel 120 is welded and fixed to the bracket longitudinal beam 112 of the bracket 110. The bracket panel 120 provides a platform for the installation and fixing of the bracket seat 130. The bracket seat 130 is welded to the bracket panel 120 and can provide a connection support foundation for the upper structure and serve as a flipping foundation, facilitating the installation and flipping of the upper structure. This structure can simultaneously connect the upper structure and the frame longitudinal beam 220. Because the bracket 110... 0 is connected to the longitudinal beam 220 of the frame. The support lug 130 can be set to a larger size, so that the support lug 130 has a larger contact area, which helps to improve the stability of the connection and the structural strength. At the same time, the larger size also reduces the precision requirements and avoids the instability of the connection between the support lug 130 and the superstructure. The force of the support lug 130 can be directly transmitted to the longitudinal beam 220 of the frame, thereby improving the overall structural load-bearing capacity. Since the bracket 110 also adopts a longitudinal and transverse combination structure, as a support for the support lug 130, it has strong structural strength and can withstand the force of the superstructure acting on the frame 200. Especially in heavy or super heavy off-road vehicles, the above implementation method changes the conventional support lug structure form and setting method to meet the high load-bearing requirements of the frame 200. This structure is suitable for the chassis of heavy or super heavy vehicles.

[0040] Please refer to Figure 2In some embodiments, the bracket 110 includes a bracket crossbeam 111 and a bracket longitudinal beam 112, which are welded together to form the structural frame of the bracket 110. Specifically, the two ends of the bracket crossbeam 111 are respectively connected to the spaced-apart bracket longitudinal beams 112. There are two bracket longitudinal beams 112 arranged in parallel. The bracket crossbeam 111 is horizontally arranged, and its two ends are respectively welded to the opposite surfaces of the two bracket longitudinal beams 112. At least one bracket crossbeam 111 is used. The bracket longitudinal beam 112 is fixed to the frame longitudinal beam 220. Specifically, the bracket longitudinal beam 112 and the frame longitudinal beam 220 are... The longitudinal beams 112 and 220 of the frame are arranged in the same direction, with surface contact between them. The bottom of the longitudinal beam 112 is then welded and fixed to the 220 of the frame. In some embodiments, two crossbeams 111 are used, with both ends of the two crossbeams 111 still welded between the two longitudinal beams 112. One crossbeam 111 has a vertical plate surface, while the other has a horizontal plate surface. In this way, the upper support lug structure 100 is welded to the frame 200 as a whole, eliminating the need to cut a notch at the rear of the frame longitudinal beam 220, improving manufacturability, and ensuring the overall structural strength of the frame 200. The support panel 120 is plate-shaped and is used to support the lug seat 130. The support panel 120 is fixed to the longitudinal beam 112. After the two longitudinal beams 112 are arranged in parallel, the bottom surface of the support panel 120 is fixed to the top of the two longitudinal beams 112 by welding. The bottom of the ear bracket 130 is welded and fixed to the bracket panel 120. The ear bracket 130 is provided with a bearing connector 132 for connecting and flipping the upper equipment. A mounting hole can be provided on the ear bracket 130, and a bearing is fixedly embedded in the mounting hole. The bearing is connected to the interface of the upper equipment.

[0041] In some embodiments, the support beam 111 and the support panel 120 are also provided with through holes 101 for weight reduction and drainage. The through holes 101 are holes penetrating both sides of the support beam 111 and both sides of the support panel 120. The through holes 101 serve both weight reduction and drainage purposes. The through holes 101 should not be too large; the hole diameter must meet strength requirements. Under these conditions, the through holes 101 reduce the weight of the support beam 111 and the support panel 120, thereby reducing the weight of the entire lug 131 structure and facilitating drainage, preventing water accumulation and corrosion. In some embodiments, the support panel 120 is also provided with a sensor support 121. The sensor support 121 has an interface or hole for installing sensors. The sensor support 121 is used to install detection sensors. The sensors use conventional sensing devices, such as infrared sensors, displacement sensors, and angle detection sensors. The sensor support 121 facilitates sensor installation for subsequent condition monitoring of the lug 131 structure.

[0042] Please refer to Figure 3and Figure 4 In some embodiments, since the upper support ear structure 100 is fixed to the frame longitudinal beam 220, and the support ear seat 130 is located above the end of the upper support ear structure 100, the support ear seat 130 is located at the rear upper part of the frame longitudinal beam 220. The support ear seat 130 and the support longitudinal beam 112 are respectively welded and fixed to both sides of the support panel 120. The positions of the support ear seat 130 and the support longitudinal beam 112 correspond, that is, the support ear seat 130 and the support longitudinal beam 112 are respectively located at the upper and lower corresponding positions of the support panel 120. The support longitudinal beam 112 indirectly bears the load on the support ear seat 130 in the vertical direction. The support ear seat 130 includes a support ear 131 and a bearing connector 132. The support ear 131 is made of high-strength steel and is integrally machined. Through the integrally formed support ear 131 structure, the support ear 131 has strong load-bearing capacity and can withstand strong loads of the upper equipment. During manufacturing, it can ensure high dimensional accuracy and good rigidity, which is convenient for mass production. The lug 131 includes multiple lug portions 131a, each lug portion 131a being a protruding structure on both sides of the lug 131. A notch is formed between adjacent lug portions 131a; that is, the top of the lug 131 is recessed inwards to form a notch. This notch serves as an interface for inserting the upper-mounted equipment. This notch design facilitates connection of the upper-mounted equipment and prevents loosening. A bearing connector 132 is fixed to the lug portion 131a. Specifically, the lug portion 131a has a shaft hole, and the bearing connector 132 is a bushing 132c. The bushing 132c has a self-lubricating function and can be made of self-lubricating material. Self-lubrication is achieved through grease storage at 32c, polishing and lubrication of the inner surface of bushing 132c, etc. Bushing 132c is inserted into the shaft hole and fixed by a locking device. The locking device is a welded edge formed by welding or other locking devices. By fixing bushing 132c to the lug 131a, the basis for bearing setting is realized. The bearing connection ensures the stability of the connection between the lug 131 and the upper equipment. The setting of lug 131a and bearing connector 132 can make the connection with the upper equipment more stable, improve the connection strength, and also meet the flexible tilting requirements of the upper equipment.

[0043] Please refer to Figure 4 and Figure 5In some embodiments, the support surface of the ear portion 131a for supporting the upper device is set as an inclined surface, so that the ear portion 131a forms a wedge-shaped structure. In the figure, the first end of the ear portion 131a has a wedge-shaped cross-section and the second end is circular. The shaft hole is located at the second end of the ear portion 131a, and the shaft hole passes through the inner and outer sides of the ear portion 131a. The radial dimension of the shaft hole is smaller on the inner side of the opposite surfaces of the two ear portions 131a, so that the bushing 132c can be fixed by being inserted into the shaft hole from the two outer sides of the ear 131. The top surface of the wedge-shaped structure in the figure is used to support the upper device and is the support surface, while the other side of the wedge-shaped structure is fixed to the bracket panel 120, that is, the bottom surface of the ear 131 is welded and fixed to the top of the bracket panel 120. Through the above arrangement, the support surface of the ear 131 has a larger contact area, which can better bear the force and improve the load-bearing capacity of the ear 131 structure. The bushing 132c is fixed by a locking member. In some embodiments, the locking member includes a baffle 132a and a baffle 132a connector. The baffle 132a is circular and its size is larger than that of the shaft hole. The bushing 132c is fixed in the shaft hole by the baffle 132a, which serves as a limiting and blocking element. A connecting hole is also provided at the outer edge of the baffle 132a. The lug portion 131a also has a mating hole at the aforementioned relative position. The mating hole is a threaded hole. The baffle 132a is fixed to the lug portion 131a by passing through the connecting hole and the mating hole through the baffle 132a connector. The bushing 132c is fixed in the lug portion 131a by the baffle 132a, which provides protection and makes the installation of the bushing 132c more stable. The baffle 132a is fixed by the baffle 132a connector. In some embodiments, the baffle 132a connector uses a screw 132b or a threaded rod. Other structures may also be used for the baffle 132a connector, as long as it ensures that the baffle 132a can be fixed to the lug 131.

[0044] Please refer to Figure 6 and Figure 7In some embodiments, the support longitudinal beam 112 includes spaced and parallel longitudinal beam side plates 112a, a top plate 112c, a cover plate 112d, a bottom plate 112e, and an end plate 112f. Two longitudinal beam side plates 112a are provided, or more may be used. The two longitudinal beam side plates 112a are vertically arranged to form a parallel structure. The longitudinal beam side plates 112a are plate-like structures, roughly in the shape of a right-angled trapezoid, narrower at the top and wider at the bottom. Thus, one end of the longitudinal beam side plate 112a is wedge-shaped. In the wedge-shaped section, the longitudinal beam side plate 112a has an inclined edge. The top end of this inclined edge extends to the bottom of the top plate 112c, and the bottom end extends above the bottom plate 112e, separated from the bottom plate 112e by a distance. The widths of the top plate 112c, cover plate 112d, bottom plate 112e, and end plate 112f are all greater than the widths of the two longitudinal beam side plates 112a. In other embodiments, the spacing of the plates 112a is wider than the overall width of all the longitudinal beam side plates 112a. The edges of the longitudinal beam side plates 112a are connected by a top plate 112c, a cover plate 112d, a bottom plate 112e, and an end plate 112f to form a cavity structure, similar to a box. The top plate 112c, the cover plate 112d, the bottom plate 112e, and the end plate 112f are perpendicular to the longitudinal beam side plates 112a. This structural form enhances the overall rigidity and structural strength of the support longitudinal beam 112. The inclined arrangement of the longitudinal beam side plates 112a and the cover plate 112d makes the support longitudinal beam 112 form a wedge-shaped structure. The wedge-shaped top surface of the wedge structure is used to bear the load of the upper equipment. Thus, the upper equipment support ear structure 100 can directly support the upper equipment, improving the overall structural bearing capacity and making it suitable for vehicles with high load-bearing requirements.

[0045] In some embodiments, the base plate 112e is connected to the frame longitudinal beam 220 along the arrangement direction of the frame longitudinal beam 220. The base plate 112e is strip-shaped and overlaps the top of the frame longitudinal beam 220. The base plate 112e is located within the width range of the frame longitudinal beam 220 at all points in the width direction, which further improves the load-bearing capacity of the support longitudinal beam 112 for the superstructure equipment. The top plate 112c is located on top of the longitudinal beam side plate 112a. The cover plate 112d is connected to the inclined edge. The bottom end of the cover plate 112d is bent, so that the cover plate 112d connects to both the inclined edge and the portion of the bottom plate 112e that is separated from the inclined edge at the side of the longitudinal beam side plate 112a. The bottom plate 112e is located at the bottom of the longitudinal beam side plate 112a. The end plate 112f is located at one end of the longitudinal beam side plate 112a. The top plate 112c, cover plate 112d, bottom plate 112e, and end plate 112f are connected end to end to form a closed loop. This structure forms a closed structure, which provides waterproofing and is simple in design. In other embodiments, the longitudinal beam side plate 112a, top plate 112c, cover plate 112d, bottom plate 112e, and end plate 112f can also be integrally formed.

[0046] In some embodiments, the support longitudinal beam 112 further includes a longitudinal beam expansion plate 112b, which is spaced apart from the longitudinal beam side plate 112a. The longitudinal beam expansion plate 112b has a bent structure, which consists of two sections. One section is parallel to the longitudinal beam side plate 112a, and the other section is connected to the side of the longitudinal beam side plate 112a by welding. Thus, the two opposite edges of the entire longitudinal beam expansion plate 112b are respectively connected to the longitudinal beam side plate 112a and the end plate 112f. The two ends of the longitudinal beam expansion plate 112b are respectively connected to the top plate 112c and the bottom plate 112e. Similarly, the longitudinal beam expansion plate 112b, the top plate 112c, the bottom plate 112e, and the end plate 112f form a cavity structure, thus providing a section with increased width on the side of the longitudinal beam side plate 112a. This arrangement can improve the structural stability of the support longitudinal beam 112 at the support panel 120.

[0047] Please refer to Figure 8 In some embodiments, the support longitudinal beam 112 further includes multiple vertical plates, including a first vertical plate 112g, a second vertical plate 112h, and a third vertical plate 112i. In other embodiments, the number of vertical plates may be different. The first vertical plate 112g and the third vertical plate 112i are channel steel, and the second vertical plate 112h is a bent steel with a cross-section in the shape of a "7". The first vertical plate 112g, the second vertical plate 112h, and the third vertical plate 112i are all vertically arranged, so that the top of the three vertical plates is vertically welded to the bottom of the support panel 120, and the bottom of the three vertical plates is vertically welded to the base plate 112e. In some embodiments, the first upright plate 112g is located between the longitudinal beam side plate 112a and the longitudinal beam expansion plate 112b, i.e., the increased width of the adjacent longitudinal beam side plate 112a. The channel steel of the first upright plate 112g is welded and fixed to the side of the longitudinal beam side plate 112a on both sides. The notch of the second upright plate 112h faces inward, and one side of the second upright plate 112h is welded and fixed to the outside of the channel steel of the first upright plate 112g. The other end of the second upright plate 112h is welded and fixed to the outside of the longitudinal beam side plate 112a. The third upright plate 112i is located between the adjacent longitudinal beam side plates 112a. The channel steel of the third upright plate 112i is welded and fixed to the inside of the longitudinal beam side plate 112a on both sides. By setting the upright plates, the load-bearing capacity of the support panel 120 can be enhanced in the vertical direction, and the support strength of the support longitudinal beam 112 can be improved.

[0048] Please refer to Figure 1In some embodiments, in order to avoid other structures on the vehicle chassis at the location of the bracket 110, the two longitudinal beam side plates 112a are provided with multiple clearance holes. There are three clearance holes, namely a round hole, a square hole with rounded corners, and a triangular hole with rounded corners. Other numbers can also be provided. By setting clearance holes, the position occupied by existing structures can be avoided, and the installation flexibility can be improved. After setting clearance holes, the two longitudinal beam side plates 112a form opposite hole edges. A liner is also provided at two of the clearance holes. The liner includes a first liner 112j and a second liner 112k. Both liner 112j and liner 112k are annular plate structures made of sheet metal. The cross-sections of the first liner 112j and liner 112k are annular. The two sides of the liner are connected to the longitudinal beam side plates 112a at the clearance holes. That is, on the cross-sections of the first liner 112j and the second liner 112k perpendicular to the annular plate, their shapes are consistent with the shapes of the aforementioned rounded square holes and rounded triangular holes. Since the liner is located between the two longitudinal beam side plates 112a, and the edges of the first liner 112j and the second liner 112k are respectively connected to the longitudinal beam side plates... The clearance hole edge of plate 112a is connected, so that the cavity structure can be sealed by the liner. A liner is also provided at the third clearance hole. That is, the cavity structure is kept closed by the liner at the above-mentioned round hole. The longitudinal beam of the bracket 112 forms a cavity structure to prevent water accumulation, corrosion and rust. A pad 112l is also provided at the end of the above-mentioned round hole. The pad 112l is located on the outside of the bracket 110. The pad 112l has an interface for external connection. This interface can be connected to the corresponding structure of the chassis of the frame 200 to ensure the installation distance of the bracket 110, so that the bracket 110 can be accurately positioned and installed.

[0049] Please refer to Figure 2 and Figure 3In some embodiments, the bracket 110 also employs a reinforcing plate 110a. The reinforcing plate 110a is a thickened plate at one end of the bracket 110, extending from one longitudinal beam 112 to the other. The reinforcing plate 110a is connected to the end plate 112f at one end of the longitudinal beam 112, specifically by welding, but bolting or other methods may also be used. In some embodiments, a closed frame structure is also provided between the bracket panel 120 and the frame longitudinal beam 220. The closed frame structure is connected to the side of the longitudinal beam 112 and is formed by at least two of the following connections: plates, grooves, or ribs. Specifically, side plates are connected to both ends of the reinforcing plate 110a. The side plates include a first side plate 110b and a second side plate 110c. The first side plate 110b and the second side plate 110c are respectively vertically welded to both ends of the reinforcing plate 110a, and the first side plate 110b... There are gaps between b and a support beam 112, and between the second side plate 110c and another support beam 112; the side plates are connected to enclosures, which include a first enclosure 110d and a second enclosure 110e with identical structures. Both the first enclosure 110d and the second enclosure 110e are formed by bending plates at a bending angle of 90°. The first enclosure 110d will be described below. The structure and connection method of the second enclosure 110e are the same. The top of the first enclosure 110d has a bent section, which is secured by screws. 132b is fixed to the bottom of the support panel 120 by welding. The vertical part of the first surrounding plate 110d is plate-shaped and is vertically welded to the top of the bottom plate 112e. The two sides of the first surrounding plate 110d are welded to the outer side of the support longitudinal beam 112 and one side of the first side plate 110b, respectively. In this way, the first side plate 110b, the first surrounding plate 110d, the second side plate 110c, and the second surrounding plate 110e form a cavity around the outer side of the support longitudinal beam 112 and the two ends of the reinforcing plate 110a. The two ends of the cavity are closed by the support panel 120 and the bottom plate 112e. The two ends of the side plate and the surrounding plate are vertically connected to the support panel 120 and the bottom plate 112e, respectively, thus forming a closed frame structure. The reinforcing plate 110a is used to enhance the structural strength and improve the load-bearing capacity at one end of the longitudinal beam 112 of the support. The structure formed by the surrounding plate, the side plate and the two ends of the reinforcing plate 110a improves the strength and rigidity of the support 110 in the vertical direction, and also plays a protective role for the inside of the cavity, preventing water and dust from entering.

[0050] Please refer to Figure 2 and Figure 9In some embodiments, to enhance the load-bearing capacity, torsional resistance, and bending resistance of the support 110, reinforcing members are added. These reinforcing members include plates, channels, or ribs. For example, the opposing surfaces of the support panel 120 and the base plate 112e are respectively provided with a first stiffening rib 110f and a second stiffening rib 110g. The first stiffening rib 110f is made of channel steel and spans across the spaced-apart longitudinal beams 112 of the support. Specifically, channel steel is used, and its two edges are welded to the bottom of the support panel 120. The second stiffening rib 110g is also made of channel steel. The two sides of the channel steel are welded to the top of the base plate 112e. The two channel steels are set along the direction of the longitudinal beam 112 of the support. The middle part of the channel steel can be directly welded to the frame 200. The first stiffening rib 110f enhances the rigidity of the support panel 120 and the second stiffening rib 110g enhances the rigidity of the base plate 112e, preventing the support panel 120 and the base plate 112e from deforming when subjected to external forces. The support 110 can withstand greater loads.

[0051] The third stiffening rib 110h, the first stiffening plate 110j, and the second stiffening plate 110k are all located within the cavity. The third stiffening rib 110h is fixed to the side of the support longitudinal beam 112. A third stiffening rib 110h is provided at each of the two support longitudinal beams 112. The third stiffening rib 110h is made of channel steel, with its two edges welded to the outer side of the longitudinal beam side plate 112a of the support longitudinal beam 112. The two edges of the first stiffening plate 110j are welded to the side of the channel steel of the third stiffening rib 110h and the side of the end plate 112f, respectively. The third stiffening rib 110h and the first stiffening plate 110j are vertically connected to the support panel 1. 20. The base plate 112e is still connected by welding. The end plate 112f is welded perpendicularly to the second stiffening plate 110k. The second stiffening plate 110k is located outside the end plate 112f. The second stiffening plate 110k and the first stiffening plate 110j mentioned above are both plate parts. There are two second stiffening plates 110k. Other quantities can be used in other embodiments. The top and bottom ends of the second stiffening plate 110k are welded and fixed to the support panel 120 and the base plate 112e, respectively. By setting the stiffening ribs 110i, the first stiffening plate 110j, and the second stiffening plate 110k, the load-bearing capacity is further enhanced by multiple vertical reinforcing members, so that the support 110 can withstand greater loads.

[0052] Please refer to Figure 2In some embodiments, the bracket 110 is further provided with other reinforcing members, including ribs 110i and diagonal ribs 110l. Both ribs 110i and diagonal ribs 110l are plate parts. The rib 110i is positioned below the lug 130, which extends from the end of the bracket panel 120 to the end of the bracket longitudinal beam 112. The rib 110i supports this extended portion. One side of the rib 110i is vertically fixed to the side of the reinforcing plate 110a, and the other side of the rib 110i is vertically fixed to the corresponding position of the lug 130 on the bracket panel 120, i.e., the bottom of the lug 130. The above fixing method is welding. The use of ribs 110i improves the structural integrity of the bracket 110. The structural rigidity of the support 110 is improved, making it more stable under stress. It also provides vertical support for the lugs 131, further enhancing their load-bearing capacity. The inclined ribs 110l are set at an angle, with both sides connected to the base plate 112e and the end plate 112f respectively. The angle of inclination is between 30° and 60°, and the connection is made by welding. One side of the inclined rib 110l is welded to the base plate 112e, with a gap between the weld position and the edge of the base plate 112e. The other side of the inclined rib 110l is welded to the bottom edge of the end plate 112f, with a gap between the weld position and the edge of the end plate 112f. The use of inclined ribs 110l improves the structural rigidity of the support 110, making it more stable under stress.

[0053] Please refer to Figure 1 In some embodiments, the upper support structure 100 simultaneously reserves an upper equipment interface, a connection lock, and a sensor mounting position. The upper equipment interface, i.e., the bracket panel 120, has external connection interfaces at both ends. The connection lock, i.e., the pad 112l, has an external interface. The pad 112l serves as an external connection lock, facilitating positioning and ensuring the installation distance of the bracket 110. The sensor mounting position is where the sensor support 121 is fixed on the bracket panel 120 by welding or bolting, facilitating sensor installation. Through the above three different external interfaces and mounting positions, the expandability of the upper support structure 100 is enhanced.

[0054] Please refer to Figure 10On the other hand, this application embodiment provides a vehicle, which includes a vehicle body 300, a frame 200, and the aforementioned upper structure bracket 100. The frame 200 is mounted on the vehicle body 300 and has a conventional structure. The frame 200 includes frame longitudinal beams 220 and frame cross beams 210. The frame longitudinal beams 220 are spaced apart, and the two ends of the frame cross beams 210 are respectively connected to the inner side of the spaced frame longitudinal beams 220. The support longitudinal beam 112 is implemented according to the upper structure bracket 100. In this example, the support longitudinal beam 112 is arranged along the longitudinal beam 220 of the frame, and the bottom of the support longitudinal beam 112 is fixed to the longitudinal beam 220 of the frame, so that the longitudinal beam 220 of the frame bears the force of the support longitudinal beam 112. The load-bearing capacity of the frame longitudinal beam 220 is indirectly improved, thereby the load-bearing capacity of the superstructure support ear structure 100 is improved, so the superstructure support ear structure 100 can provide better torsional and bending resistance, and the vehicle can carry heavier superstructure equipment, thus making it suitable for heavy or super heavy vehicles.
