Description

Technical Field

[0001] This disclosure relates to the field of vehicle component technology, specifically to a lift roof, a roof panel, and a vehicle. Background Technology

[0002] With the diversification of the automotive industry, people have also developed a demand for cars for outdoor camping, which requires cars to not only meet basic needs but also add configurations based on camping scenarios.

[0003] In related technologies, a lift-up roof panel and a rooftop tent are added to the top of the car to allow users to set up a tent on the car roof to meet their camping needs. However, the lift-up roof panel in these technologies has poor structural strength and often suffers from deformation and other problems. Utility Model Content

[0004] To overcome the problems existing in the related technologies, this disclosure provides a lifting roof, a roof panel, and a vehicle.

[0005] According to a first aspect of the present disclosure, a liftable roof is provided, which is used to be liftably disposed on a vehicle roof and can be used as part of the vehicle roof. The liftable roof includes an outer roof and an inner roof, which are mated and connected. The outer roof and the inner roof are made of metal.

[0006] The outer and inner roof panels are joined together to form a double-layer structure, effectively improving the lifting roof's resistance to bending, compression, and impact. Secondly, both the outer and inner roof panels are made of metal, a material with high strength and rigidity. The double-layer metal structure further distributes external loads, reducing the risk of localized deformation or damage to the roof and meeting the long-term load-bearing requirements of the vehicle roof. Furthermore, the lifting roof can be used as part of the vehicle roof panel, allowing it to be assembled simultaneously with the roof panel production, effectively improving production efficiency and eliminating the need for subsequent assembly processes, thus enhancing assembly convenience.

[0007] In some embodiments, the outer top plate includes an outer top plate body and a first flange, the first flange being connected to at least a portion of the outer periphery of the outer top plate body; The inner top plate includes an inner top plate body and a second flange, the second flange being connected to at least a portion of the outer periphery of the inner top plate body; The first flange and the second flange are connected by welding.

[0008] The welding of the first and second flanges forms a continuous closed annular weld, firmly connecting the edges of the outer and inner roof panels. Compared to flat bonding or bolt fixing, flange welding significantly improves the bending, torsional, and shear strength of the weld surface by increasing the welding contact area. This effectively resists vibrations, bumps, or mechanical stresses during vehicle operation and prevents edge cracking or weld detachment.

[0009] In some embodiments, the first flange is arranged around the circumferential edge of the outer top plate body, and the second flange is arranged around the circumferential edge of the inner top plate body; wherein the width of the first flange and the second flange is between 5 mm and 9 mm.

[0010] By limiting the width of the first flange and the second flange to between 5mm and 9mm, a sealing strip can be used to seal both the first flange and the second flange, which can also effectively shorten the length of the sealing strip and reduce its cost.

[0011] In some embodiments, the outer top plate and the inner top plate are integrally stamped from aluminum alloy.

[0012] Specifically, the outer top plate body and the first flange can be constructed as a single-piece molding structure. For example, the outer top plate body and the first flange can be integrally stamped from aluminum alloy, thereby ensuring the strength of the outer top plate while reducing its weight. Similarly, the inner top plate body and the second flange can also be constructed as a single-piece molding structure. For example, the inner top plate body and the second flange can be integrally stamped from aluminum alloy, thereby ensuring the strength of the inner top plate while reducing its weight.

[0013] In some embodiments, the outer top plate includes a middle portion of the outer top plate and side portions of the outer top plate connecting its left and right sides, both the middle portion and the side portions of the outer top plate extending in a front-rear direction, and the side portions of the outer top plate at least partially protruding from the outer surface of the middle portion of the outer top plate.

[0014] By making the side of the outer roof panel at least partially protrude from the outer surface of the middle of the outer roof panel, rainwater on the middle surface of the outer roof panel can be prevented from flowing across the side of the outer roof panel and onto the side of the vehicle when driving in rainy weather, thereby minimizing the impact on the driver's vision and improving driving safety.

[0015] In some embodiments, the outer top plate side portion includes a side body and a raised rib, the side body and the raised rib both extending in the front-rear direction and connected in the left-right direction, and the middle portion of the outer top plate is connected to the raised rib in the left-right direction; wherein, at least the raised rib protrudes from the outer surface of the middle portion of the outer top plate.

[0016] Among them, the raised rib extends along the front-to-back direction and protrudes from the outer surface of the middle part of the outer top plate. The raised rib can significantly improve the bending stiffness and torsional stiffness of the side of the outer top plate in the left-to-right direction, resisting lateral deformation caused by bumps, turns or lifting operations during vehicle operation.

[0017] Secondly, the side body and the raised ribs are connected to the middle of the outer top plate in the left and right directions. When the outer top plate is subjected to external loads, the raised ribs can disperse the concentrated stress to the side body and the middle of the outer top plate, avoiding cracking or deformation caused by excessive local stress and improving the durability of the structure.

[0018] In some embodiments, the width of the raised rib in the left-right direction is between 80mm and 100mm, and the height of the raised rib protruding from the middle of the outer top plate is not less than 5mm.

[0019] The width of the raised rib in the left-right direction can be 80mm, 90mm, or 100mm. This disclosure does not limit the specific width of the raised rib. Furthermore, the raised rib within this width range provides sufficient lateral support area, effectively resisting deformation caused by lateral forces during vehicle operation.

[0020] In some embodiments, at least one groove is recessed on the outer surface of the middle portion of the outer top plate, and the groove extends in the front-rear direction.

[0021] The grooves can be designed to strengthen the middle section of the outer top plate.

[0022] In some embodiments, the depth of the groove is between 1.5 mm and 2 mm.

[0023] By setting the depth of the groove between 1.5mm and 2mm, the rigidity of the large surface of the outer top plate is improved, while the surface quality problems of the outer top plate in the middle are effectively avoided during the stamping process.

[0024] In some embodiments, at least one of the grooves includes a first groove and a second groove, wherein the first groove and the second groove are spaced apart in the left-right direction; The inner top plate is formed with a first reinforcing rib and a second reinforcing rib, both of which extend along the front-back direction and are spaced apart in the left-right direction. The first reinforcing rib is opposite to the first groove and protrudes towards the first groove, and the second reinforcing rib is opposite to the second groove and protrudes towards the second groove.

[0025] The first and second grooves on the outer top plate not only reinforce the structure but also act as weight-reducing grooves, effectively reducing the weight of the outer top plate. Meanwhile, the first and second reinforcing ribs on the inner top plate protrude accordingly, effectively distributing stress across the grooved areas of the outer top plate and preventing localized deformation.

[0026] In some embodiments, at least one of the grooves further includes a third groove, the third groove extending in a front-back direction and spaced apart from the first groove and the second groove in a left-right direction; The inner top plate also has at least one third reinforcing rib, which is arranged in an X shape between the first reinforcing rib and the second reinforcing rib to define a reinforcing cavity with the middle part of the outer top plate.

[0027] The third groove extends along the front-to-back direction and is spaced apart from the first and second grooves in the left-to-right direction. This layout can effectively disperse external pressure and avoid stress concentration. Secondly, the X-shaped third reinforcing rib is located between the first and second reinforcing ribs, forming a more complex three-dimensional support structure, which significantly improves the overall rigidity and bending resistance of the structure, prevents structural deformation or collapse, and provides additional support force, especially when subjected to impact or vibration.

[0028] In some embodiments, the lifting top plate further includes vibration damping adhesive, and at least one vibration damping groove is recessed on the surface of the inner top plate near the outer top plate. The vibration damping adhesive is disposed in the vibration damping groove and bonded to the inner wall of the outer top plate.

[0029] The design of the vibration damping grooves provides specific spatial locations for the vibration damping adhesive, allowing it to be evenly distributed and fully contact the inner and outer roof panels. The adhesive, with its excellent elasticity and damping properties, forms a buffer layer between the inner and outer roof panels, absorbing and dissipating vibration energy. This design significantly reduces vibration transmission from the external environment or the vehicle's interior, thereby improving ride comfort.

[0030] In some embodiments, the vibration isolation grooves are provided in multiple ways, and the multiple vibration isolation grooves include at least one first vibration isolation groove group. The first vibration isolation groove group includes at least two first vibration isolation grooves, and the first vibration isolation grooves are arranged at intervals in the front-back direction.

[0031] The design of the first vibration isolation groove group can more evenly disperse vibration energy and form multiple independent vibration isolation areas. The first vibration isolation grooves, which are set in pairs in the front and back directions, can effectively cut off the vibration transmission path and reduce the possibility of vibration waves propagating in a single direction. The vibration isolation adhesive is filled in the vibration isolation grooves and bonded to the outer top plate, which further enhances the vibration isolation effect and reduces the impact of external vibration on the internal space.

[0032] In some embodiments, the distance between two adjacent first vibration isolation grooves in the front-to-back direction is no greater than 150 mm.

[0033] By controlling the spacing between two adjacent first vibration isolation grooves to within 150mm, it can be ensured that the vibration wave encounters more vibration isolation points during propagation, thereby more effectively cutting off the vibration transmission path; this dense arrangement helps to form a continuous vibration isolation barrier, reducing the possibility of direct transmission of vibration energy; in addition, the smaller spacing size means that the vibration isolation adhesive can cover a larger area, further enhancing the vibration isolation effect.

[0034] In some embodiments, the inner top plate is provided with at least one lifting mounting part, and the lifting top plate further includes at least one lifting reinforcing plate; The lifting reinforcement plate is connected to the inner top plate on the side near the outer top plate and is opposite to the lifting mounting part; The lifting mounting section and the lifting reinforcing plate are detachably connected to the lifting device that drives the lifting top plate to rise and fall.

[0035] The lifting reinforcement plate can strengthen the structure of the lifting installation part, avoiding stress concentration and deformation or tearing problems.

[0036] In some embodiments, the inner top plate is provided with at least one canopy mounting portion, and the lifting top plate further includes at least one canopy reinforcing plate; The canopy reinforcement plate is connected to the inner top plate on the side near the outer top plate and is opposite to the canopy mounting part; The canopy mounting section and the canopy reinforcement plate are used for detachable connection with the roof tent.

[0037] The canopy reinforcement plate can strengthen the structure of the canopy installation area, preventing stress concentration that could lead to deformation or tearing.

[0038] According to a second aspect of the present disclosure, a vehicle roof panel is also provided, the vehicle roof panel including a vehicle roof panel body, a lifting device and the lifting roof panel, the lifting roof panel being movably disposed on the vehicle roof panel body, and the lifting device being disposed on the vehicle roof panel body.

[0039] According to a third aspect of the present disclosure, a vehicle is also provided, the vehicle including the aforementioned roof panel.

[0040] The technical solutions provided by the embodiments of this disclosure can include the following beneficial effects: the outer roof panel and the inner roof panel are joined together to form a double-layer structure, thereby effectively improving the bending, compressive, and impact resistance of the lift roof panel. Secondly, the outer and inner roof panels are made of metal, which inherently possesses high strength and rigidity. The double-layer metal structure further disperses external loads, reducing the risk of localized deformation or damage to the roof panel and meeting the long-term load-bearing requirements of the vehicle roof. Furthermore, the lift roof panel can be used as part of the vehicle roof panel, allowing for assembly during the production of the vehicle roof panel, effectively improving production efficiency and eliminating the need for subsequent assembly processes, thus enhancing assembly convenience.

Detailed Implementation

[0051] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0052] In this disclosure, unless otherwise stated, directional terms such as up, down, front, back, left, and right refer to the definitions of up, down, front, back, left, and right as defined under normal vehicle use conditions. For details, please refer to [link / reference needed]. Figure 1 As shown. The directional terms used, such as "inner" and "outer", refer to the inner and outer parts of the specific structural outline; the terms used, such as "first" and "second", are only used to distinguish one element from another and do not have any sequential or important meaning.

[0053] In the description of this disclosure, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0054] Reference Figures 1 to 7 As shown, this disclosure provides a liftable roof panel 1, which is used to be liftably mounted on the roof panel of a vehicle and can be used as part of the roof panel. The liftable roof panel 1 includes an outer roof panel 11 and an inner roof panel 12, which are connected to each other. The outer roof panel 11 and the inner roof panel 12 are made of metal.

[0055] In the above technical solution, firstly, the outer roof panel 11 and the inner roof panel 12 are joined together to form a double-layer structure, which effectively improves the bending, compressive, and impact resistance of the lifting roof panel 1. Secondly, the outer roof panel 11 and the inner roof panel 12 are made of metal, which has high strength and rigidity. The double-layer metal structure further disperses external loads, reduces the risk of local deformation or damage to the roof panel, and meets the long-term load-bearing requirements of the vehicle roof. In addition, the lifting roof panel 1 can be used as part of the vehicle roof panel, and can be assembled at the same time as the vehicle roof panel, effectively improving production efficiency and eliminating the need for subsequent assembly processes, thus improving assembly convenience.

[0056] In one implementation, reference Figure 3 , Figure 4 , Figure 6 as well as Figure 7 As shown, the outer top plate 11 includes an outer top plate body 111 and a first flange 112, the first flange 112 being connected to at least a portion of the outer periphery of the outer top plate body 111; the inner top plate 12 includes an inner top plate body 121 and a second flange 122, the second flange 122 being connected to at least a portion of the outer periphery of the inner top plate body 121; wherein, the first flange 112 and the second flange 122 are connected by welding.

[0057] In this embodiment, the welding of the first flange 112 and the second flange 122 can form a continuous closed annular weld, firmly connecting the edges of the outer top plate body 111 and the inner top plate body 121. Compared with flat bonding or bolt fixing, flange welding significantly improves the bending, torsional and shear strength of the weld surface by increasing the welding contact area, which can effectively resist vibration, bumps or mechanical stress during vehicle operation or lifting, and avoid edge cracking or weld detachment.

[0058] Secondly, the first flange 112 and the second flange 122 can be locally thickened only at the edges of the outer top plate 11 and the inner top plate 12, ensuring connection strength while avoiding excessive thickening of the overall sheet metal, thus achieving the goal of localized reinforcement and overall lightweighting. Compared to overall thickening of the sheet metal, the flange design reduces metal usage, lowering weight and cost. Furthermore, the first flange 112 and the second flange 122 can be welded together using a spot welding method.

[0059] Specifically, the outer top plate body 111 and the first flange 112 can be constructed as an integrally formed structure. For example, the outer top plate body 111 and the first flange 112 can be integrally stamped from aluminum alloy, thereby ensuring the strength of the outer top plate 11 while reducing its weight. The inner top plate body 121 and the second flange 122 can also be constructed as an integrally formed structure. For example, the inner top plate body 121 and the second flange 122 can be integrally stamped from aluminum alloy, thereby ensuring the strength of the inner top plate 12 while reducing its weight. However, this disclosure does not limit the specific materials and forming methods of the outer top plate 11 and the inner top plate 12.

[0060] In addition, the outer top plate 11 and inner top plate 12 made of metal are easier to maintain and have a higher appearance quality than those made of plastic, and do not have the VOC (Volatile Organic Compounds) problem caused by plastic materials.

[0061] Optionally, the first flange 112 is arranged around the circumferential edge of the outer top plate body 111, and the second flange 122 is arranged around the circumferential edge of the inner top plate body 121; wherein the width of the first flange 112 and the second flange 122 is between 5 mm and 9 mm.

[0062] In this embodiment, the width of the first flange 112 and the second flange 122 can be 5mm, 7mm, or 9mm. This disclosure does not limit the specific width dimensions. Furthermore, by limiting the width of the first flange 112 and the second flange 122 to between 5mm and 9mm, a sealing strip can be used to seal both when sealing the first flange 112 and the second flange 122, effectively shortening the length of the sealing strip and reducing its cost.

[0063] In other implementations, refer to Figure 3 and Figure 5 As shown, the outer top plate 11 includes an outer top plate middle portion 113 and an outer top plate side portion 114 connecting its left and right sides. Both the outer top plate middle portion 113 and the outer top plate side portion 114 extend in the front-back direction, and the outer top plate side portion 114 at least partially protrudes from the outer surface of the outer top plate middle portion 113.

[0064] In this embodiment, by making the outer roof panel side portion 114 at least partially protrude from the outer surface of the outer roof panel middle portion 113, when driving in rainy weather, rainwater on the surface of the outer roof panel middle portion 113 can be prevented from flowing across the outer roof panel side portion 114 to the side of the vehicle as much as possible, thereby minimizing the impact on the driver's vision and improving driving safety.

[0065] Optionally, refer to Figure 5 As shown, the outer top plate side portion 114 includes a side body 1141 and a raised rib 1142. The side body 1141 and the raised rib 1142 both extend in the front-back direction and are connected in the left-right direction. The outer top plate middle portion 113 is connected to the raised rib 1142 in the left-right direction. At least the raised rib 1142 protrudes from the outer surface of the outer top plate middle portion 113.

[0066] In this embodiment, the raised rib 1142 extends in the front-rear direction and protrudes from the outer surface of the middle part 113 of the outer top plate. The raised rib 1142 can significantly improve the bending stiffness and torsional stiffness of the side part 114 of the outer top plate in the left-right direction, resisting lateral deformation caused by bumps, turns or lifting operations during vehicle operation.

[0067] Secondly, the side body 1141 and the raised rib 1142 are connected to the middle part 113 of the outer top plate in the left and right directions. When the outer top plate 11 is subjected to external load, the raised rib 1142 can disperse the concentrated stress to the side body 1141 and the middle part 113 of the outer top plate, avoid cracking or deformation caused by excessive local stress, and improve the durability of the structure.

[0068] In addition, the protruding design of the raised rib 1142 can form a guide ridge extending in the front and rear direction. This guide ridge can guide rainwater to the front and rear sides of the roof panel, and avoid rainwater on the surface of the middle part 113 of the outer roof panel from flowing over the side part 114 of the outer roof panel and flowing to the side of the vehicle as much as possible, thereby minimizing the impact on the driver's vision and improving driving safety.

[0069] In other embodiments, the width of the raised rib 1142 in the left-right direction is between 80mm and 100mm, and the height of the raised rib 1142 protruding from the middle part 113 of the outer top plate is not less than 5mm.

[0070] In this embodiment, the width of the protruding rib 1142 in the left-right direction can be 80mm, 90mm, or 100mm. This disclosure does not limit the specific width of the protruding rib 1142. Furthermore, this width range of the protruding rib 1142 provides sufficient lateral support area, effectively resisting deformation caused by lateral forces during vehicle movement. For example, when the vehicle turns, the side of the roof experiences centrifugal force; a wider protruding rib can distribute the load to a larger area of ​​the outer roof panel center 113 and the side body 1141, avoiding localized stress concentration.

[0071] Optionally, refer to Figure 3 As shown, at least one groove 1130 is recessed on the outer surface of the middle portion 113 of the outer top plate, and the groove 1130 extends in the front-rear direction. By providing the groove 1130, the strength of the middle portion 113 of the outer top plate can be enhanced.

[0072] Optionally, the depth of the groove 1130 is between 1.5mm and 2mm. For example, the depth of the groove 1130 is 1.5mm, or the depth of the groove 1130 is 1.7mm, or the depth of the groove 1130 is 2mm. By setting the depth of the groove 1130 between 1.5mm and 2mm, while improving the rigidity of the large surface of the outer top plate center 113, it is also possible to effectively avoid surface quality problems of the outer shape surface of the outer top plate center 113 during the stamping process.

[0073] In other embodiments, refer to Figure 3 and Figure 6 As shown, at least one groove 1130 includes a first groove 1131 and a second groove 1132, which are spaced apart in the left-right direction; the inner top plate 12 is formed with a first reinforcing rib 123 and a second reinforcing rib 124, which both extend in the front-back direction and are spaced apart in the left-right direction; wherein, the first reinforcing rib 123 is opposite to the first groove 1131 and protrudes toward the first groove 1131, and the second reinforcing rib 124 is opposite to the second groove 1132 and protrudes toward the second groove 1132.

[0074] In this embodiment, the first groove 1131 and the second groove 1132 of the outer top plate 11, in addition to reinforcing the structure, can also be regarded as weight-reducing grooves, effectively reducing the weight of the outer top plate 11. In addition, the first reinforcing rib 123 and the second reinforcing rib 124 of the inner top plate 12 protrude accordingly. The reinforcing ribs of the inner top plate 12 can effectively share the stress in the groove area of ​​the outer top plate 11 and avoid local deformation.

[0075] In another embodiment, refer to Figure 3 and Figure 6 As shown, at least one groove 1130 also includes a third groove 1133, which extends in the front-back direction and is spaced apart from the first groove 1131 and the second groove 1132 in the left-right direction; the inner top plate 12 also has at least one third reinforcing rib 125, which is X-shaped and disposed between the first reinforcing rib 123 and the second reinforcing rib 124 to define a reinforcing cavity with the middle part 113 of the outer top plate.

[0076] In this embodiment, the third groove 1133 extends in the front-to-back direction and is spaced apart from the first groove 1131 and the second groove 1132 in the left-to-right direction. This arrangement can effectively disperse external pressure and avoid stress concentration. Secondly, the X-shaped third reinforcing rib 125 is located between the first reinforcing rib 123 and the second reinforcing rib 124, forming a more complex three-dimensional support structure, which significantly improves the overall rigidity and bending resistance of the structure, prevents structural deformation or collapse, and provides additional support force, especially when subjected to impact or vibration. However, this disclosure does not limit the specific structural shape of the third reinforcing rib 125.

[0077] Optionally, refer to Figure 6 As shown, the lifting top plate 1 also includes vibration damping adhesive (not shown). The inner top plate 12 has at least one vibration damping groove 128 recessed on the surface near the outer top plate 11. The vibration damping adhesive is disposed in the vibration damping groove 128 and bonded to the inner wall of the outer top plate 11.

[0078] In this embodiment, the design of the vibration damping groove 128 provides a specific spatial position for the vibration damping adhesive, allowing it to be evenly distributed and fully contact the inner roof panel 12 and the outer roof panel 11. The vibration damping adhesive has good elasticity and damping characteristics, forming a buffer layer between the inner roof panel 12 and the outer roof panel 11 to absorb and dissipate vibration energy. This design can significantly reduce the transmission of vibrations from the external environment or the vehicle interior, thereby improving ride comfort.

[0079] Optionally, refer to Figure 6 As shown, there are multiple vibration isolation grooves 128, including at least one first vibration isolation groove group 1281. The first vibration isolation groove group 1281 includes at least two first vibration isolation grooves 1282, which are spaced apart in pairs in the front-back direction.

[0080] In this embodiment, the design of the first vibration isolation groove group 1281 can more evenly disperse vibration energy and form multiple independent vibration isolation areas; the first vibration isolation grooves 1282, which are arranged in pairs in the front-back direction, can effectively cut off the vibration transmission path and reduce the possibility of vibration waves propagating in a single direction. The vibration isolation adhesive is filled in the vibration isolation grooves 128 and bonded to the outer top plate, which further enhances the vibration isolation effect and reduces the impact of external vibration on the internal space.

[0081] Optionally, the distance between two adjacent first vibration isolation grooves 1282 in the front-back direction is no more than 150mm. Controlling the distance between two adjacent first vibration isolation grooves 1282 to within 150mm ensures that the vibration wave encounters more vibration isolation points during propagation, thereby more effectively cutting off the vibration transmission path; this dense arrangement helps to form a continuous vibration isolation barrier, reducing the possibility of direct transmission of vibration energy; in addition, the smaller distance means that the vibration isolation adhesive can cover a larger area, further enhancing the vibration isolation effect.

[0082] In one implementation, reference Figure 1 As shown, the inner top plate 12 is provided with at least one lifting mounting part 126, and the lifting top plate 1 also includes at least one lifting reinforcing plate 13; the lifting reinforcing plate 13 is connected to the side of the inner top plate 12 near the outer top plate 11 and is opposite to the lifting mounting part 126; the lifting mounting part 126 and the lifting reinforcing plate 13 are used to be detachably connected to the lifting device that drives the lifting top plate 1 to lift.

[0083] In this embodiment, the lifting mounting part 126 is used to be detachably connected to the lifting device, wherein the lifting device is used to drive the lifting top plate 1 to move in the vertical direction. The lifting mounting part 126 can be constructed in any suitable shape and structure, and this disclosure does not limit it. As for the connection method, any suitable connection method can also be selected. For example, the lifting mounting part 126 and the lifting device are connected by bolts.

[0084] Furthermore, the lifting reinforcement plate 13 can be constructed in any suitable shape and structure, and this disclosure does not limit it.
