Technical Field

[0001] The present application relates to the field of vehicle manufacturing technology, and in particular, to a trolley. Background Art

[0002] The existing trolley can only carry out the assembly of front-end modules of one type of vehicle at a time. When the front-end modules of different models need to be assembled, the support structure on the working surface of the trolley needs to be replaced or the support structure needs to be removed from the working surface of the trolley and then installed at a different position on the working surface so that the support structure can adapt to the assembly of front-end modules of different models, which seriously affects the assembly efficiency of the front-end modules. Summary of the invention

[0003] The embodiment of the present application provides a trolley to improve the efficiency of packaging operations.

[0004] The embodiment of the present application provides a trolley, comprising a base and a workbench. The workbench is rotatably mounted on the base, and has two opposite work surfaces. The workbench can rotate relative to the base so that one of the two work surfaces faces upward or the other faces upward, and each work surface is provided with a support structure for supporting a workpiece.

[0005] In the above technical solution, the workbench can rotate relative to the base so that one of the two working surfaces is facing upward or the other is facing upward, that is, the workbench can rotate relative to the base to switch between the two working surfaces, and the two working surfaces can be used for at least two types of workpiece operations, without the need to replace the support structure after disassembly or adjust the position of the support structure after disassembly, thereby improving the work efficiency of the workpiece. In addition, the support structure does not need to be disassembled or the number of disassembly times is small, which can avoid or reduce the wear of the support structure during the disassembly process.

[0006] In some embodiments of the present application, the support structure includes a plurality of fixed support members and a plurality of movable support members; the fixed support members are fixed to the working surface, and the movable support members are adjustably disposed on the working surface.

[0007] In the above technical solution, the movable support is adjustable on the working surface, so that the movable support can move relative to the working surface to adjust the position of the movable support, so that the distance between the movable support and / or between the movable support and the fixed support changes, so that each working surface can perform multiple workpiece packaging operations. The movable support moves relative to the working surface to adjust the position of the movable support, so that the working surface can switch from a state where one workpiece can be packaged to a state where another workpiece can be packaged. The switching method is convenient and fast, and the workpiece packaging efficiency can be improved.

[0008] In some embodiments of the present application, the trolley further includes a rotating seat, which is rotatably disposed on the work surface, and at least one movable support member is provided on the rotating seat, and the rotating seat is used to adjust the position of the movable support member when rotating relative to the work surface.

[0009] In the above technical solution, the movable support is installed on the rotating seat, and the position of the movable support is adjusted by rotating the rotating seat. The adjustment method is convenient and fast, and can avoid wear of the movable support during the position adjustment process.

[0010] In some embodiments of the present application, the rotating seat has a first position and a second position, and the rotating seat can switch between the first position and the second position by rotating relative to the workbench; when the rotating seat is in the first position, the movable support member can cooperate with the fixed support member to support the first workpiece; when the rotating seat is in the second position, the movable support member can cooperate with the fixed support member to support the second workpiece.

[0011] In the above technical solution, the rotating seat switches between the first position and the second position, which can drive the movable support installed on the rotating seat to move, thereby adjusting the position of the movable support so that each working surface can perform at least two types of workpiece packaging operations, making the application range of the lathe wider.

[0012] In some embodiments of the present application, a first limit member and a second limit member are provided on the working surface, and the rotating seat can reach the second position by rotating from the first position along the first direction, and can reach the first position by rotating from the second position along the second direction, and the first direction and the second direction are opposite; the first limit member is used to resist the rotating seat when the rotating seat is in the first position to prevent the rotating seat from rotating in the second direction; the second limit member is used to resist the rotating seat when the rotating seat is in the second position to prevent the rotating seat from rotating in the first direction.

[0013] In the above technical solution, the first limit member and the second limit member respectively define the limit positions of the rotating seat to rotate in the second direction and the first direction, and together define the rotation range of the rotating seat to prevent the rotating seat from rotating excessively. In addition, according to whether the rotating seat abuts against the first limit member and the second limit member, it can be judged whether the rotating seat has moved into place in the first position and the second position.

[0014] In some embodiments of the present application, the rotation axis of the rotating seat is perpendicular to the working surface.

[0015] In the above technical solution, the rotation axis of the rotating seat is perpendicular to the working surface, so that the rotating seat can rotate more flexibly and the position of the movable support is easily adjusted.

[0016] In some embodiments of the present application, the workbench has a through hole penetrating the two work surfaces.

[0017] In the above technical solution, the provision of the through hole can reduce the weight of the workbench, so that the workbench can be rotated more easily relative to the base.

[0018] In some embodiments of the present application, a plurality of fixing supports are arranged around the through hole at intervals.

[0019] In the above technical solution, a plurality of fixed supports are arranged at intervals around the through hole. When the workpiece is supported by the plurality of fixed supports, the through hole is located below the workpiece. The arrangement of the through hole can avoid interference between the workpiece and the workbench.

[0020] In some embodiments of the present application, each workpiece further includes a support pin, and each work surface is also provided with a support pin, and the support pin is used to insert and position the workpiece.

[0021] In the above technical solution, the provision of the support pins can position the workpiece and ensure the stability of the workpiece when operating on the workpiece.

[0022] In some embodiments of the present application, the trolley also includes a limiting structure, which is used to allow the workbench to rotate along a third direction relative to the base and prevent the workbench from rotating along a fourth direction; the third direction is opposite to the fourth direction.

[0023] In the above technical solution, the limit structure enables the workbench to rotate in one direction, improves the stability of the workbench rotation, and makes it easier to keep the work surface in a horizontal upward state. The limit mechanism allows the workbench to rotate in one direction only, avoiding bidirectional rotation, reducing the difficulty of operating the workbench, and avoiding the safety risks caused by the bidirectional rotation of the workbench.

[0024] In some embodiments of the present application, the trolley includes a locking mechanism, which is configured to releasably lock the workbench to keep the work surface in a horizontal state.

[0025] In the above technical solution, the locking mechanism can lock the workbench at a specified position to keep the work surface horizontal, without the need for manual leveling of the work surface, thereby ensuring the accuracy of the operation.

[0026] In some embodiments of the present application, the locking mechanism includes a first locking member and a second locking member, both of which are rotatably connected to the base and are respectively located on both sides of the rotation axis of the workbench; the first locking member has a first state and a second state, and the second locking member has a third state and a fourth state; the first locking member is used to prevent the workbench from rotating in a third direction and allow the workbench to rotate in a fourth direction when it is in the first state; the first locking member is also used to allow the workbench to rotate in the third direction and allow the workbench to rotate in the fourth direction in the second state; the second locking member is used to prevent the workbench from rotating in the fourth direction and allow the workbench to rotate in the third direction in the third state; the second locking member is also used to allow the workpiece to rotate in the fourth direction and allow the workbench to rotate in the third direction in the fourth state.

[0027] In the above technical solution, the first locking member and the second locking member cooperate to prevent the workbench from rotating in a third direction and a fourth direction opposite to the third direction, respectively. The first locking member and the second locking member cooperate to keep the workbench in a horizontal state, thereby keeping the working surface of the workbench in a horizontal state.

[0028] In some embodiments of the present application, the locking mechanism also includes a reset member, and the second locking member is connected to the base through the reset member. When the force applied by the workbench to the second locking member reaches a threshold, the second locking member can overcome the elastic force of the reset member and switch from the third state to the fourth state.

[0029] In the above technical solution, the setting of the reset member can not only enable the second locking member to have a certain locking ability so that the second locking member prevents the workbench from rotating in the fourth direction, but also enable the second locking member to rotate when the external force acting on the workbench is greater than a threshold value, and switch from the third state to the fourth state, thereby preventing external force from damaging the second locking member.

[0030] In some embodiments of the present application, a first inclined surface for slidingly cooperating with a first locking member and a first abutting surface for cooperating with a second locking member are provided on the workbench; the first locking member slides relative to the first inclined surface and can switch between a first state and a second state; the second locking member slides relative to the first abutting surface and can switch between a third state and a fourth state.

[0031] In the above technical solution, the first inclined surface makes it easier for the first locking member to switch between the first state and the second state, and the first abutting surface makes it easier for the second locking member to switch between the third state and the fourth state.

[0049] Example

[0050] like Figure 1 , Figure 2 As shown, the embodiment of the present application provides a trolley 100, which includes a workbench 10 and a base 30. The workbench 10 is rotatably mounted on the base 30, and the workbench 10 has two opposite work surfaces 11. The workbench 10 can rotate relative to the base so that one of the two work surfaces 11 faces upward or the other faces upward, and each work surface 11 is provided with a support structure 20, which is used to support a workpiece.

[0051] The workbench 10 is rotatably mounted on a rotating shaft 31 on a base 30. The rotation direction of the workbench 10 relative to the base 30 is consistent with the axis of the rotating shaft 31.

[0052] In this embodiment, a plurality of rollers 32 are installed at the bottom of the base 30 , and the rotation of the plurality of rollers 32 can drive the trolley 100 to move, thereby facilitating the positioning of the trolley 100 .

[0053] When one working surface 11 faces upward and the other working surface 11 faces downward, the workpiece can be supported by the support structure 20 on the upward working surface 11, and the workpiece can be packaged. When the workpiece needs to be supported by the support structure 20 on the other working surface 11, it is only necessary to apply external force to the workbench 10 to rotate the workbench 10 relative to the base to achieve the switching of the two working surfaces 11 of the workbench 10.

[0054] The workpiece may be a front-end module of a vehicle or other workpiece suitable for the trolley 100 in the present application. In the present embodiment, the structure of the trolley 100 in the present application is introduced with the workpiece being the front-end module of the vehicle. The front-end module of a vehicle refers to a carrier at the front of the vehicle, which may integrate other functional components of the vehicle, such as a radiator plate in a cooling system. The structure and shape of the front-end module are designed according to the vehicle body requirements. Therefore, the size and structural shape of the front-end modules of different vehicle models are different. The trolley 100 used to assemble the front-end modules needs to adapt to front-end modules of different structural shapes and sizes.

[0055] When the sizes of the two working surfaces 11 and / or the sizes or arrangements of the corresponding support structures 20 on the two working surfaces 11 are different, the support structures 20 on the two working surfaces 11 can support front-end modules of different vehicle models. In this embodiment, the workbench 10 can rotate relative to the base so that one of the two working surfaces 11 is facing upward or the other is facing upward, that is, the workbench 10 can rotate relative to the base to switch between the two working surfaces 11. The two working surfaces 11 can be used for at least two front-end module operations, and there is no need to replace the support structure 20 after disassembly or adjust the position of the support structure 20 after disassembly, thereby improving the work efficiency of the workpiece. In addition, the support structure 20 may not be disassembled or the number of disassembly times is small, which can avoid or reduce the wear of the support structure 20 during the disassembly process.

[0056] In some embodiments, the workbench 10 includes a first support plate 12, a second support plate 13 and two support beams 14, the first support plate 12 and the second support plate 13 are arranged relatively spaced apart, and the two support beams 14 are spaced apart and supported between the first support plate 12 and the second support plate 13, so that there is a gap between the first support plate 12 and the second support plate 13, so that the workbench 10 is a hollow structure, which reduces the weight of the workbench 10. The two support beams 14 can be set as a hollow structure to further reduce the weight of the workbench 10. One of the two working surfaces 11 is set on the side of the first support plate 12 away from the second support plate 13, and the other of the two working surfaces 11 is set on the side of the second support plate 13 away from the first support plate 12.

[0057] In some embodiments, the workbench 10 has a through hole 15 that passes through the two work surfaces 11. The provision of the through hole 15 can reduce the weight of the workbench 10, so that the workbench 10 can be more easily rotated relative to the base.

[0058] In other embodiments, the workbench 10 may also be a solid plate-shaped structure.

[0059] In some embodiments, the trolley 100 further includes a limiting structure 40, which is used to allow the workbench 10 to rotate relative to the base in a third direction and prevent the workbench 10 from rotating in a fourth direction; the third direction is opposite to the fourth direction. The limiting structure 40 enables the workbench 10 to rotate in one direction, improves the stability of the rotation of the workbench 10, and makes it easier to keep the work surface 11 in a horizontal upward state. The limiting mechanism allows the workbench 10 to rotate in one direction only when rotating, avoiding bidirectional rotation, reducing the difficulty of operating the workbench 10, and avoiding the safety risks caused by the bidirectional rotation of the workbench 10 to the operation.

[0060] The limiting structure 40 may be a one-way bearing.

[0061] In some embodiments, the support structure 20 includes a plurality of fixed support members 21 and a plurality of movable support members 22 ; the fixed support members 21 are fixed to the working surface 11 , and the movable support members 22 are adjustably disposed on the working surface 11 .

The fixed support member 21 can be fixed to the working surface 11 by a non-detachable method such as welding. The fixed support member 21 can also be fixed to the working surface 11 by a detachable method such as bolts, screws, etc., which is convenient for the maintenance and replacement of the fixed support member 21.

[0063] like Figure 3-Figure 5 As shown, each fixed support member 21 includes a first mounting seat 211, a first support column 212 and a first support block 213. The axial ends of the first support column 212 are connected to the first mounting seat 211 and the first support block 213. The first support seat is provided with a plurality of first mounting holes 2111 for inserting bolts, screws, etc. The plurality of first mounting holes 2111 are arranged around the first support column 212 on the first mounting seat 211. The first mounting seat 211 is fixed to the working surface 11 by screws, bolts, etc., and the first support block 213 is used to support the front-end module.

[0064] like Figure 3 As shown, in some embodiments, the first support block 213 of the partially or entirely fixed support member 21 includes a first support portion 2131 and a first blocking portion 2132, the first support portion 2131 is connected to the first support column 212, the first blocking portion 2132 is connected to the first support portion 2131 and extends in a direction away from the first support column to form an L-shaped first support block 213, which can also be understood as the first support portion 2131 and the first blocking portion 2132 forming a two-level stepped structure. The first support portion 2131 supports the front-end module from bottom to top, and the first blocking portion 2132 can play a lateral limiting role on the workpiece.

[0065] like Figure 4As shown, in some embodiments, the first support block 213 of the fixed support member 21 partially or entirely includes a first support portion 2131, a second support portion 2133, and a first blocking portion 2132. The first support portion 2131 is connected to the first support column 212, the second support portion 2133 is connected to the first support portion 2131 and extends in a direction away from the first support column 212, and the first blocking portion 2132 is connected to the second support portion 2133 and extends in a direction away from the first support column, so that the first support portion 2131, the second support portion 2133 and the first blocking portion 2132 form a three-level stepped structure. The first support portion 2131 and the second support portion 2133 can support the front-end module from bottom to top, and the first blocking portion 2132 can play a lateral limiting role on the workpiece.

[0066] like Figure 5 As shown, in some embodiments, the first support block 213 of part or all of the fixed support member 21 includes a first connecting portion 2134, a first limiting portion 2135 and a second limiting portion 2136, the first connecting portion 2134 is connected to the first support column 212, the first limiting portion 2135 and the second limiting portion 2136 are both connected to the first connecting portion 2134 and extend in a direction away from the first support column 212, the first limiting portion 2135 and the second limiting portion 2136 are arranged relatively spaced apart, the first limiting portion 2135 and the second limiting portion define a first positioning groove 214, part of the structure of the front-end module (such as a protrusion, a latch, etc. on the front-end module) can be limited in the first positioning groove 214, and the first limiting portion 2135 and the second limiting portion 2136 play a limiting role in the arrangement direction.

[0067] Of course, in other embodiments, according to actual needs, such as according to the specific structure of the workpiece and the structure of the position where the workpiece is supported, the structure of the first supporting block 213 may have other designs.

[0068] In some embodiments, a plurality of fixed supports 21 are arranged at intervals around the through hole 15. When the workpiece is supported by the plurality of fixed supports 21, the through hole 15 is located below the workpiece, and the arrangement of the through hole 15 can prevent the workpiece from interfering with the workbench 10.

[0069] The movable support 22 is adjustable in position on the work surface 11, so that the movable support 22 can move relative to the work surface 11 to adjust the position of the movable support 22, so that the distance between the movable support 22 and / or between the movable support 22 and the fixed support 21 can be changed, so that a variety of workpieces can be packaged on each work surface 11. The movable support 22 moves relative to the work surface 11 to adjust the position of the movable support 22, so that the work surface 11 can be switched from a state where one workpiece can be packaged to a state where another workpiece can be packaged. The switching method is convenient and fast, and the workpiece packaging efficiency can be improved.

[0070] like Figure 6 As shown, the structure of the movable support member 22 can refer to the structure of the fixed support member 21. For example, each movable support member 22 includes a second mounting seat 221, a second support column 222 and a second support block 223. The axial ends of the second support column 222 are connected to the second mounting seat 221 and the second support block 223. The second support seat is provided with a plurality of second mounting holes 2211 for inserting bolts, screws, etc. The plurality of second mounting holes 2211 are arranged around the second support column 222 on the second mounting seat 221. The second mounting seat 221 is adjustably connected to the working surface 11 by screws, bolts, etc., and the second support block 223 is used to support the front-end module.

[0071] In some embodiments, the second support block 223 of part or all of the movable support members 22 includes a third support portion 2231 and a second blocking portion 2232, wherein the third support portion 2231 is connected to the second support column 222, and the second blocking portion 2232 is connected to the third support portion 2231 and extends in a direction away from the second support column to form an L-shaped second support block 223. It can also be understood that the third support portion 2231 and the second blocking portion 2232 form a two-level stepped structure. The third support portion 2231 supports the front-end module from bottom to top, and the second blocking portion 2232 can play a lateral limiting role on the workpiece.

[0072] In some embodiments, the second support block 223 of part or all of the movable support members 22 includes a third support portion 2231, a fourth support portion (not shown in the figure), and a second blocking portion 2232.

The third support portion 2231 and the fourth support portion can support the front-end module from bottom to top, and the second blocking portion 2232 can play a lateral limiting role on the workpiece.

[0073] In some embodiments, the second support block 223 of part or all of the movable support members 22 includes a second connecting portion (not shown in the figure), a third limiting portion (not shown in the figure) and a fourth limiting portion (not shown in the figure), the second connecting portion is connected to the second support column 222, the third limiting portion and the fourth limiting portion are both connected to the second connecting portion and extend in a direction away from the second support column 222, the third limiting portion and the fourth limiting portion are arranged at relative intervals, the third limiting portion and the fourth limiting portion define a second positioning groove, some structures of the front-end module (such as the protrusions, latches, etc. on the front-end module) can be limited in the second positioning groove, and the third limiting portion and the fourth limiting portion play a limiting role in the arrangement direction.

By installing the movable support member 22 on the rotating seat 50, the position of the movable support member 22 is adjusted by rotating the rotating seat 50, and the adjustment method is convenient and fast, and can avoid the wear of the movable support member 22 during the position adjustment process.

[0076] like Figure 6 As shown, each rotating seat 50 is provided with two movable support members 22, and the rotating seat 50 includes a first rotating part 51 and a second rotating part 52. One end of the first rotating part 51 and one end of the second rotating part 52 are connected to form an L-shaped rotating seat 50. The first rotating part 51 and the second rotating part 52 are respectively installed with a movable support member 22. The rotating seat 50 is rotatably connected to the workbench 10 through a rotating shaft 53.

[0077] The rotating seat 50 has a first position and a second position. The rotating seat 50 can be switched between the first position and the second position by rotating relative to the workbench 10. When the rotating seat 50 is in the first position, the movable support 22 can cooperate with the fixed support 21 to support the first workpiece. When the rotating seat 50 is in the second position, the movable support 22 can cooperate with the fixed support 21 to support the second workpiece. The rotating seat 50 switches between the first position and the second position, which can drive the movable support 22 installed on the rotating seat 50 to move, thereby adjusting the position of the movable support 22, so that each working surface 11 can perform at least two types of workpiece packaging operations, making the application range of the platform wider.

[0078] The first workpiece and the second workpiece have different structures and / or sizes. If the workpiece is a front-end module, the first workpiece and the second workpiece are front-end modules of different vehicle models.

[0079] In some embodiments, the rotation axis of the rotating seat 50 is perpendicular to the working surface 11 , so that the rotating seat 50 can rotate more flexibly and the position of the movable support member 22 can be adjusted easily.

[0080] like Figure 7As shown, in some embodiments, a first limit member 60 and a second limit member 70 are provided on the working surface 11, and the rotating seat 50 can rotate from the first position along the first direction A1 to reach the second position, and the rotating seat 50 can rotate from the second position along the second direction A2 to reach the first position, and the first direction A1 and the second direction A2 are opposite; the first limit member 60 is used to abut against the rotating seat 50 when the rotating seat 50 is located at the first position to prevent the rotating seat 50 from rotating along the second direction A2; the second limit member 70 is used to abut against the rotating seat 50 when the rotating seat 50 is located at the second position to prevent the rotating seat 50 from rotating along the first direction A1.

[0081] The first stopper 60 and the second stopper 70 respectively define the limit positions of the rotating seat 50 for rotating in the second direction A2 and the first direction A1, and together define the rotation range of the rotating seat 50 to prevent the rotating seat 50 from rotating excessively. In addition, according to whether the rotating seat 50 abuts against the first stopper 60 and the second stopper 70, it can be determined whether the rotating seat 50 has moved into place in the first position and the second position.

[0082] In some embodiments, each workpiece further includes a support pin 80, and each work surface 11 is also provided with a support pin 80, which is used to insert and position the workpiece. The setting of the support pin 80 can position the workpiece and ensure the stability of the workpiece when operating the workpiece.

[0083] like Figure 8 As shown, the support pin 80 includes a positioning pin 81 and a fixing seat 82 connected to one axial end of the positioning pin 81, the fixing seat 82 is used to connect with the workbench 10 to achieve the installation of the support pin 80 on the workbench 10, and a plurality of third mounting holes 821 are provided on the fixing seat 82, and the third mounting holes 821 are used to insert screws or bolts to achieve the installation of the support pin 80 on the workbench 10.

[0084] There are multiple support pins 80, some of which are fixedly mounted on the working surface 11, and another part of which are adjustably mounted on the working surface 11. By adjusting the positions of the adjustable support pins 80, the trolley 100 can adapt to the operations of different front-end modules, so that each working surface 11 can perform subassembly operations of front-end modules of multiple vehicle models.

[0085] like Fig. 9As shown, in some embodiments, the trolley 100 further includes a rotating seat 90, which is rotatably disposed on the working surface 11, and at least one supporting pin 80 is disposed on the rotating seat 90, and the rotating seat 90 is used to adjust the position of the supporting pin 80 when rotating relative to the working surface 11. By installing the supporting pin 80 on the rotating seat 90, the position of the supporting pin 80 is adjusted by rotating the rotating seat 90, and the adjustment method is convenient and fast, and the wear of the supporting pin 80 during the position adjustment process can be avoided.

[0086] like Fig. 9 As shown, each rotating seat 90 is provided with two supporting pins 80, and the rotating seat 90 includes a first rotating part and a second rotating part. One end of the first rotating part and one end of the second rotating part are connected to form an L-shaped rotating seat 90. The first rotating part and the second rotating part are respectively installed with a supporting pin 80, and the rotating seat 90 is rotatably connected to the workbench 10 through a rotating pin 91.

[0087] The rotation method of the rotating seat 90 can refer to the rotating seat 50, and will not be repeated here. In addition, a third limiter 92 and a fourth limiter (not shown in the figure) can also be set on both sides of the rotating seat 90, and the third limiter 92 and the fourth limiter respectively define the limit positions of the rotating seat 90 rotating in opposite directions.

[0088] In some embodiments, the trolley 100 includes a locking mechanism, which is configured to releasably lock the workbench 10 so that the work surface 11 remains in a horizontal state. The locking mechanism can lock the workbench 10 in a specified position so that the work surface 11 remains in a horizontal state, without the need for manual leveling of the work surface 11, thereby ensuring the accuracy of the operation.

[0089] Please continue to see Figure 1 , Figure 2 In some embodiments, the locking mechanism 110 includes a first locking member (not shown in the figure) and a second locking member 112, the first locking member and the second locking member 112 are both rotatably connected to the base 30 and are respectively located on both sides of the rotation axis of the workbench 10; the first locking member has a first state and a second state, and the second locking member 112 has a third state and a fourth state; the first locking member is used to prevent the workbench 10 from rotating along the third direction and allow the workbench 10 to rotate along the fourth direction when it is in the first state; the first locking member is also used to allow the workbench 10 to rotate along the third direction and allow the workbench 10 to rotate along the fourth direction in the second state; the second locking member 112 is used to prevent the workbench 10 from rotating along the fourth direction and allow the workbench 10 to rotate along the third direction in the third state; the second locking member 112 is also used to allow the workpiece to rotate along the fourth direction and allow the workbench 10 to rotate along the third direction in the fourth state.

[0090] When the workbench 10 is in a horizontal state, the first locking member and the second locking member 112 are both located below the workbench 10 , and the first locking member and the second locking member 112 are respectively located at two diagonally opposite positions of the workbench 10 .

[0091] In some embodiments, the first locking member and the second locking member 112 may also be located on the same straight edge of the workbench 10 and on both sides of the rotation axis of the workbench 10 .

[0092] In some embodiments, the locking mechanism 110 further includes a reset member 113, and the second locking member 112 is connected to the base 30 through the reset member. When the force applied by the workbench 10 to the second locking member 112 reaches a threshold value, the second locking member 112 can overcome the elastic force of the reset member 113 and switch from the third state to the fourth state. The setting of the reset member 113 can not only enable the second locking member 112 to have a certain locking ability so that the second locking member 112 prevents the workbench 10 from rotating in the fourth direction, but also enable the second locking member 112 to rotate when the external force acting on the workbench 10 is greater than the threshold value, and switch from the third state to the fourth state to prevent the second locking member 112 from being damaged by external forces.

[0093] The reset element 113 may be an elastic element such as a spring or a torsion spring.

[0094] Please continue to see Figure 1 , Figure 2 In some embodiments, the workbench 10 is provided with a first inclined surface 17 for slidingly cooperating with the first locking member and a first abutting surface 18 for cooperating with the second locking member 112; the first locking member slides relative to the first inclined surface 17 and can switch between the first state and the second state; the second locking member 112 slides relative to the first abutting surface 18 and can switch between the third state and the fourth state.

[0095] The first inclined surface 17 makes it easier for the first locking member to switch between the first state and the second state. There are two first inclined surfaces 17 , and the two first inclined surfaces 17 are located on the two working surfaces 11 respectively.

[0096] The first abutting surface 18 is a plane parallel to the working surface 11 .

[0097] The rotation axis of the first locking member is perpendicular to the horizontal plane, that is, the first locking member rotates in the horizontal plane to switch between the first state and the second state, and when the first locking member switches between the first state and the second state, the first locking member slides along the first inclined surface 17. When the first locking member is in the first state, the first locking member is in contact with the first inclined surface 17, and when the first locking member is in the second state, the first locking member is separated from the first inclined surface 17.

[0098] The rotation axis of the second locking member 112 is parallel to the horizontal plane, and the second locking member 112 rotates in the vertical plane to switch between the third state and the fourth state. When the second locking member 112 switches between the third state and the fourth state, the second locking member 112 slides along the first abutting surface 18. When the second locking member 112 is in the third state, the second locking member 112 is in contact with the first abutting surface 18, and when the second locking member 112 is in the fourth state, the second locking member 112 is separated from the first abutting surface 18.

[0099] In some embodiments, two first abutment surfaces 18 are provided on the workbench 10, and the two first abutment surfaces 18 are arranged along the diagonal corners of the workbench 10. The locking mechanism 110 includes two second locking members 112, and the second locking members 112 are arranged one-to-one corresponding to the first abutment surfaces 18. One of the two second locking members 112 is used to prevent the workbench 10 from rotating along the third direction and allow the workbench 10 to rotate along the fourth direction. The other second locking member 112 is used to prevent the workbench 10 from rotating along the fourth direction and allow the workbench 10 to rotate along the third direction.

[0100] Each second locking member 112 is connected to the base 30 via a reset member 113. When the force applied by the workbench 10 to the second locking member 112 reaches a threshold, the second locking member 112 can overcome the elastic force of the reset member 113 and switch the state so that the corresponding second locking member 112 can allow the workbench 10 to rotate in the direction blocked by the second locking member 112. For example, a second locking member 112 is used to prevent the workbench 10 from rotating in the third direction and allow the workbench 10 to rotate in the fourth direction. When the force applied by the workbench 10 to the second locking member 112 exceeds the threshold of the elastic force of the reset member 113 corresponding to the second locking member 112, the second locking member 112 overcomes the elastic force of the reset member 113 and rotates relative to the base 30, so that the second locking member 112 allows the workbench 10 to rotate in the third direction.

[0101] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
