[0007] In some possible implementations, the first U-shaped connector includes a main body segment and a bent segment; The main body segment is a U-shaped opening facing downwards and is connected to the transverse connecting part; The two bent segments are located on opposite sides of the main body segment along the second direction, and are bent toward the first end or the second end of the first direction, respectively. Preferably, the two bent segments are bent along a first end or a second end toward the first direction and in directions opposite to each other.
[0008] In some possible implementations, the second U-shaped connector includes a bottom section and two vertically extending sections; The bottom section is connected to the fixing part; The two vertical extension segments are located on opposite sides of the bottom segment on the horizontal plane, forming a U-shape with the bottom segment; Preferably, the vertical extension section is cylindrical.

[0010] In some possible implementations, the support mechanism further includes at least two first positioning elements; At least two of the first positioning elements are spaced apart along the second direction and are both connected to the support frame, wherein the second direction is perpendicular to the first direction; The first positioning members of the two support mechanisms are respectively located on the two crossbeams of the vehicle chassis, either facing away from each other or facing each other. Both beams extend along the second direction, and the two beams are spaced apart along the first direction.
[0011] In some possible implementations, the support mechanism further includes two second positioning elements; Both second positioning members are connected to the support frame and are located on opposite sides of the support frame along the second direction; Both of the second positioning elements have positioning planes, and the two positioning planes are parallel to each other and are located on opposite sides of the two second positioning elements.

[0020] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.
[0021] This embodiment relates to a DKD vehicle body transfer device, which includes two support mechanisms 1. The two support mechanisms 1 are adapted to support the vehicle body on both sides along a first direction 001 under the vehicle body. For example, the first direction 001 can be the front-rear direction of the vehicle body, and the two support mechanisms 1 can support the vehicle body on the front and rear sides under the vehicle body respectively, thereby achieving stable load-bearing of the vehicle body.
[0022] refer to Figure 1 As shown, the support mechanism 1 includes a support frame 11 and a traveling assembly 12. The support frame 11 is adapted to support the vehicle body. The traveling assembly 12 is connected to the support frame 11, enabling the support frame 11 to move.
[0023] For example, the walking assembly 12 can be installed at the bottom of the support frame 11, and the top of the support frame 11 can be directly supported under the chassis of the vehicle body.
[0024] As described above, the DKD vehicle body transfer device includes two mutually separate support mechanisms 1.
[0025] During transfer, the two support mechanisms 1 can be transported to a designated area on the production line using an AGV (Automated Guided Vehicle). Then, a lift can move the vehicle body above the DKD vehicle body transfer device, ensuring stable support of the vehicle body by the two support mechanisms 1. The two support mechanisms 1 can be supported by corresponding support frames 11 on both sides of the vehicle body chassis along the first direction 001, thus supporting the vehicle body. The movement of the support mechanisms 1 and the vehicle body on them can be achieved through the walking assembly 12.
[0026] When not in use, on the one hand, since the two support mechanisms 1 do not need to include the connecting parts between them, the total floor space can be smaller. On the other hand, the two support mechanisms 1 do not need to be connected, so their relative positions when idle can be freely changed, or they can be placed separately. At the same time, since each support mechanism 1 occupies a small area, the number of locations that can be selected when placing each support mechanism 1 can also be increased, thus greatly improving the flexibility of placing the DKD vehicle body transfer device. Therefore, floor space savings can be achieved.
[0027] In some examples, the walking component 12 of each support mechanism 1 may include at least one walking wheel 121, and the walking components 12 of two support mechanisms 1 may include at least three walking wheels 121 in total, so as to form at least a triangular support with stability to jointly support the vehicle body.
[0028] Optionally, the traveling wheel 121 can be a swivel wheel or a fixed wheel. The tires of the traveling wheel 121 can be airless hollow tires, with an integrated inner and outer tire and a hollow structure, which have the advantages of being puncture-resistant, elastic, wear-resistant, and having low rolling resistance, and can have a long service life.
[0029] For example, in Figure 1 In the process, the walking component 12 of one of the support mechanisms 1 may include two walking wheels 121, and the walking component 12 of the other support mechanism 1 may include one walking wheel 121.
[0030] For example, the traveling components 12 of the two support mechanisms 1 may each include two or more traveling wheels 121. The number of traveling wheels 121 in the traveling components 12 of the two support mechanisms 1 may be equal or unequal. For instance, the traveling components 12 of both support mechanisms 1 may include two, three, or four traveling wheels 121; alternatively, one support mechanism 1 may have a traveling component 12 with two traveling wheels 121, while the other support mechanism 1 may have a traveling component 12 with three traveling wheels 121.
[0031] In some examples, reference Figure 1As shown, the support frame 11 includes a transverse connecting part 111, a transverse extension part 112, and at least three support parts 113.
[0032] The lateral connecting portion 111 is connected to the traveling assembly 12, and the lateral connecting portion 111 extends along a second direction 002, wherein the second direction 002 is perpendicular to the first direction 001. For example, the second direction 002 can be the left-right direction of the vehicle body. Figure 1 In the middle, the two walking wheels 121 of the walking assembly 12 can be respectively installed on the lower side of both ends of the transverse connecting part 111 along the second direction 002.
[0033] Combination Figure 2 As shown, the first end of the lateral extension 112 is connected to the connecting part 111, and the second end of the lateral extension 112 extends along the first direction 001.
[0034] Furthermore, at least three support portions 113 are respectively connected to the second end of the transverse connecting portion 111 and the transverse extension portion 112.
[0035] Since the lateral extension 112 and the lateral connecting part 111 extend along the first direction 001 and the second direction 002 that are perpendicular to each other, they can have enough space together in the horizontal range so that at least three support parts 113 can be non-collinear. Thus, each support frame 11 can achieve at least triangular support for the vehicle body through the corresponding at least three support parts 113, thereby improving the stability of the vehicle body support.
[0036] For example, in Figure 1 In the support frame 11, there may be four support parts 113, two of which may be located at two symmetrical positions along the second direction 002 of the transverse connecting part 111, and the other two support parts 113 may be located at two symmetrical positions along the second direction 002 of the second end of the transverse extension part 112, together forming a quadrilateral support.
[0037] In some examples, the lateral connecting part 111 and the lateral extension part 112 can be directly fixed to the corresponding support part 113 by welding, bolts or other means, or they can be indirectly fixed to the corresponding support part 113 by connecting components. This can increase the flexibility of the connection between the lateral connecting part 111 and the lateral extension part 112 and the support part 113, making it easier to avoid some structures on the vehicle body and prevent interference.
[0038] In some examples, reference Figure 3 and combined Figure 1As shown, when the walking assembly 12 includes at least two walking wheels 121, the lateral connecting portion 111 includes a main lateral beam 1111 and two reinforcing connecting assemblies 1112. The main lateral beam 1111 can extend along a second direction 002. The first end of the lateral extension 112 can be fixedly connected to the main lateral beam 1111. The two reinforcing connecting assemblies 1112 can be symmetrically located at both ends of the main lateral beam 1111.
[0039] like Figure 4 As shown, the reinforced connection assembly 1112 includes a first vertical beam 11121, a second vertical beam 11122, and an auxiliary transverse beam 11123.
[0040] The first end of the first vertical beam 11121 is fixedly connected to one end of the corresponding main transverse beam 1111, and the second end of the first vertical beam 11121 can extend along a third direction 003. This third direction 003 is perpendicular to both the first direction 001 and the second direction 003. For example, the third direction 003 can be the vertical direction of the vehicle body.
[0041] The second vertical beam 11122 is located on the side of the first vertical beam 11121 facing another reinforcing connection component 1112, and the first end of the second vertical beam 11122 is fixedly connected to the corresponding end of the main transverse beam 1111, while the second end of the second vertical beam 11122 can extend along a third direction 003. Combined with... Figure 3 As shown, the support 113 can be fixedly connected to the second end of the second vertical beam 11122 by a connecting member.
[0042] The auxiliary transverse beam 11123 can extend along the second direction 002, and the length of the second vertical beam 11122 can be greater than the length of the first vertical beam 11121, so that the first end of the auxiliary transverse beam 11123 can be fixedly connected to the middle part of the second vertical beam 11122, and the middle part of the auxiliary transverse beam 11123 can be fixedly connected to the second end of the second vertical beam 11122, so that the second vertical beam 11122 is located between the auxiliary transverse beam 11123 and the main transverse beam 1111.
[0043] The two traveling wheels 121 can be installed at the second end of the two auxiliary transverse beams 11123 respectively.
[0044] As described above, the transverse connecting part 111 can have higher strength and can withstand greater forces. At the same time, the two second vertical beams 11122 and the middle part of the main transverse beam 1111 can form a U-shaped clearance space to avoid interference with the chassis of the vehicle body.
[0045] In some examples, the reinforcing connection assembly 1112 also includes a mounting plate 11124, which can be attached and fixed to the lower side of the second end of the auxiliary transverse beam 11123 by means of bolts, welding, etc. The traveling wheel 121 can be mounted on the lower side of the mounting plate 11124. Thus, the mounting plate 11124 provides sufficient space for the installation of the traveling wheel 121.
[0046] In some examples, the reinforcing connection assembly 1112 further includes multiple right-angle reinforcing plates 11125, which can be located on opposite sides of the auxiliary transverse beam 11123 along the first direction 001. The right-angled sides of the right-angle reinforcing plates 11125 can be bonded and fixed to the surface of the corresponding side of the auxiliary transverse beam 11123 and the mounting plate 11125 by welding or other means. This can improve the stability of the connection between the auxiliary transverse beam 11123 and the mounting plate 11125, thereby improving the stability of the connection between the traveling wheel 121 and the support frame 11.
[0047] In some examples, reference Figure 5 As shown, the lateral extension 112 includes at least two extension segments 1121 and a connecting segment 1122. The at least two extension segments 1121 extend along a first direction 001, and the at least two extension segments 1121 are spaced apart along a second direction 002.
[0048] like Figure 1 As shown, the lateral extension 112 may include two extension segments 1121, but in other possible examples, the lateral extension 112 may include two extension segments 1121, three extension segments 1121, or four extension segments 1121, etc.
[0049] At least the first ends of both extension segments 1121 are connected to the transverse connecting portion 111. For example... Figure 1 As shown, the first ends of the two extension sections 1121 can be fixedly connected to the main transverse beam 1111 of the transverse connection part 111.
[0050] The connecting segment 1122 can be connected to the second end of at least two extension segments 1121. Figure 1 As shown, the second ends of the two extension sections 1121 can be fixedly connected to the main transverse beam 1111 of the transverse connection part 111.
[0051] The corresponding support part 113 can be fixedly connected to the connecting section 1122, such as Figure 1 As shown, the two support parts 113 can be fixedly connected to one end of the connecting section 1122 by connecting members.
[0052] Therefore, while ensuring the structural strength of the support frame 11, the material used for the support frame 11 can be saved and the weight of the support frame 11 can be reduced.
[0053] In some examples, combined Figure 1 and Figure 2 As shown, the second end of the lateral extension 112 extends toward another support mechanism 1 along the first direction 001. When carrying the vehicle body, the distance between the lateral connecting portions 111 of the two support mechanisms 1 can be greater, thereby the distance between the traveling components 12 of the two support mechanisms 1 can be greater, thus improving the stability of the vehicle body load.
[0054] In some examples, reference Figure 1 As shown, the support frame 11 also includes a first U-shaped connecting portion 114. The first U-shaped connecting portion 114 is connected to the transverse connecting portion 111 or the transverse extension portion 112.
[0055] For example Figure 1 and combined Figure 3 As shown, the first U-shaped connecting portion 114 can be connected to the main transverse beam 1111 of the transverse connecting portion 111. However, in other possible examples, the first U-shaped connecting portion 114 can also be connected to the transverse extension portion 112. The first U-shaped connecting portion 114 and the transverse connecting portion 111 or the transverse extension portion 112 can be fixedly connected by welding, bolts, or other means.
[0056] Continue to refer to Figure 1 As shown, the opening of the first U-shaped connecting portion 114 faces downward, and the two ends of the first U-shaped connecting portion 114 are spaced apart along the second direction 002. For example, the first U-shaped connecting portion 114 can be a plate-like structure with an opening on the lower side. The plate-like first U-shaped connecting portion 114 can be fixedly connected to the middle part of the side of the transverse connecting portion 111 away from the transverse extension portion 112 by means of bolts, welding, etc.
[0057] Continue to refer to Figure 1 As shown, the DKD vehicle body transfer device also includes a connector 2, which includes a fixed part 21 connected to the body and a second U-shaped connecting part 22.
[0058] The fixing part 21 is adapted to be connected to the traction device 3. For example Figure 11 As shown, the traction device 3 can be a forklift. Combined with... Figure 1 As shown, the fixing part 21 can be connected to the fork teeth 31 of the forklift.
[0059] The opening of the second U-shaped connector 22 faces upward, so that the opening of the second U-shaped connector 22 can be inserted into the opening of the first U-shaped connector 114.
[0060] For example Figure 1 As shown, when the opening of the second U-shaped connecting part 22 is inserted into the opening of the first U-shaped connecting part 114, the two ends of the second U-shaped connecting part 22 can be located on both sides of the first U-shaped connecting part 114 along the first direction 001.
[0061] Therefore, by connecting the fixing part 21 to the traction device 3 and inserting the opening of the second U-shaped connecting part 22 into the opening of the first U-shaped connecting part 114, the DKD body transfer device can be moved by pulling the traction device 3.
[0062] In some examples, combined Figure 1 and Figure 2 As shown, when the second end of the lateral extension 112 extends toward another support mechanism 1 along the first direction 001, the first U-shaped connecting portion 114 connects with the lateral connecting portion 111. Therefore, when carrying the vehicle body, the first U-shaped connecting portion 114 can be located in the area near the periphery of the lower side of the vehicle body. When the traction device 3 tractions the DKD vehicle body transfer device, it does not need to extend into the inner area of the lower side of the vehicle body. Therefore, the vehicle body carried on the support mechanism 1 is less likely to interfere with the traction device 3, facilitating the traction of the DKD vehicle body transfer device and improving transfer efficiency.
[0063] In some examples, the fixing part 21 may include two clamping plates 211 and a plurality of rod-shaped second fixing members 212. For example... Figure 1 As shown, two clamping plates 211 can be located on the upper and lower sides of the fork tooth 31, respectively. Multiple second fasteners 212 can penetrate the clamping plates 211 at their respective positions on opposite sides of the fork tooth 31, allowing the clamping plates 211 to clamp the fork tooth 31. For example, the second fasteners 212 can be bolts, screws, pins, etc. This facilitates a convenient fixed connection between the second fasteners 212 and the fork tooth 31.
[0064] Among them, such as Figure 1 As shown, the second U-shaped connecting part 22 can be fixedly connected to the clamping plate 211 located on the upper side.
[0065] In some examples, reference Figure 5 As shown, the first U-shaped connecting part 114 includes a main body section 1141 and a bent section 1142.
[0066] refer to Figure 5 and combined Figure 1 As shown, the main body segment 1141 can be a U-shape with the opening facing downwards. The two bent segments 1142 are located on opposite sides of the main body segment 1141 along the second direction 002, and are bent toward the first end or the second end of the first direction 001, respectively.
[0067] For example, in Figure 5 In the middle, the main body segment 1141 can be fixedly connected to the middle of the side of the transverse connecting part 111 away from the transverse extension part 112, and the two bent segments 1142 can be bent toward the side away from the transverse extension part 112.
[0068] Therefore, when the opening of the second U-shaped connecting part 22 is inserted into the opening of the first U-shaped connecting part 114, the bending section 1142 can limit the two ends of the second U-shaped connecting part 22. When the traction device turns, the end of the second U-shaped connecting part 22 can abut against the bending section 1142, thereby driving the DKD body transfer device to turn in time, improving the flexibility and stability of the traction device when pulling the DKD body transfer device to turn.
[0069] In some examples, the two bent segments 1142 are bent along directions toward either the first end or the second end of the first direction 001 and are opposite to each other. For example, in Figure 5 In the middle, when the main body segment 1141 is fixedly connected to the middle of the side of the transverse connecting portion 111 away from the transverse extension portion 112, the bending segment 1142 can be bent toward the side away from the transverse extension portion 112 and away from each other.
[0070] In this way, an acute angle can be avoided between the bent section 1142 and the main body section 1141, and when the end of the second U-shaped connecting part 22 abuts against the bent section 1142, the second U-shaped connecting part 22 and the first U-shaped connecting part 114 are less likely to experience excessive wear.
[0071] In some examples, reference Figure 6 As shown, the second U-shaped connecting portion 22 includes a bottom section 221 and two vertically extending sections 222.
[0072] The bottom section 221 is connected to the fixing part 21. For example... Figure 6 As shown, the second U-shaped connecting portion 22 may further include a support section 223. Combined with... Figure 1 As shown, the bottom end of the support section 223 can be fixedly connected to the fixing part 1 by welding, bolts, or other means, and the top end of the support section 223 can be fixedly connected to the lower surface of the bottom section 221 by welding, bolts, or other means. The bottom section 221 can be plate-shaped, and the support section 223 can be cylindrical.
[0073] Continue to refer to Figure 6 As shown, the two vertical extension segments 222 are located on opposite sides of the bottom segment 221 on the horizontal plane, forming a U-shape with the bottom segment 221. For example, the bottom ends of the two vertical extension segments 222 can be fixedly connected to opposite sides of the upper surface of the bottom segment 221 by welding, bolts, or other means.
[0074] In some examples, reference Figure 6 As shown, the vertical extension 222 is cylindrical, which can avoid contact with the first U-shaped connecting part 114 through the corners, which helps to reduce the wear between the first U-shaped connecting part 114 and the second U-shaped connecting part 22, and can improve the service life of the first U-shaped connecting part 114 and the second U-shaped connecting part 22.
[0075] In some examples, reference Figure 1 As shown, the support frame 11 has multiple fixing holes 115 and corresponding first fixing members 116. For example, in Figure 1 In this case, the support frame 11 may have four fixing holes 115. However, in other possible examples, the support frame 11 may have two fixing holes 115, three fixing holes 115, five fixing holes 115, or six fixing holes 115, etc.
[0076] The positions of the multiple fixing holes 115 correspond to the multiple mounting holes on the chassis of the vehicle body. The first fixing member 116 is rod-shaped and can pass through the corresponding mounting holes and fixing holes 115 in sequence to fix the support frame 11 to the vehicle body. The first fixing member 116 can be a bolt, rivet, or pin, etc.
[0077] For example, the vehicle body can be moved by a lift until the mounting hole and fixing hole 115 are aligned, and then the support frame 11 and the vehicle body can be fixed by the first fixing member 116 to achieve stable load bearing of the vehicle body by the support mechanism 1.
[0078] Thus, the vehicle body can be fixed on the support frame 11 through the fixing hole 115 and the corresponding first fixing member 116, which can improve the stability of the support frame 11 in supporting the vehicle body.
[0079] In some examples, reference Figure 1 As shown, when the support frame 11 includes a support portion 113, the fixing holes 115 correspond one-to-one with the support portion 113, and the fixing holes 115 are located at the top of the corresponding support portion 113.
[0080] For example, in Figure 1 In the support frame 11, there may be four support parts 113, and the support frame 11 may have four fixing holes 115, which may be located at the top of the corresponding support parts 113 respectively.
[0081] Since the fixing hole 115 is located at the top of the support part 113, and the support part 113 is supported on the underside of the chassis and in direct contact with the chassis, when the first fixing member 116 passes through the mounting hole and fixing hole 115 on the chassis, the support part 113 can be tightly pressed against the chassis to achieve effective fixation.
[0082] Generally, the chassis of the vehicle can have two crossbeams 5, both of which can extend along the left-right direction of the vehicle body, and the two crossbeams 5 can be spaced apart along the front-rear direction. In some examples, refer to Figure 1 As shown, the support mechanism 1 also includes at least two first positioning elements 13. For example, in Figure 1In this embodiment, the support mechanism 1 includes two first positioning elements 13. However, in other possible examples, the support mechanism 1 may include three, four, or five first positioning elements 13, etc.
[0083] Continue to refer to Figure 1 As shown, at least two first positioning members 13 are spaced apart along the second direction 002 and are both connected to the support frame 11. The second direction 002 is perpendicular to the first direction 001. Thus, the second direction 002 can be the left-right direction of the vehicle body, and the first direction 001 can be the front-rear direction of the vehicle body.
[0084] by Figure 1 Taking the middle support mechanism 1 as an example, which includes two first positioning members 13, both first positioning members 13 can be connected to the transverse connecting part 111 of the support frame 11 by welding, bolts or other means. When the transverse connecting part 111 includes the main crossbeam 1111, both first positioning members 13 can be fixedly connected to the main crossbeam 1111.
[0085] Among them, the first positioning element 13 of the two support mechanisms 1 is located on the two sides of the two crossbeams 5 that are opposite to each other or facing each other.
[0086] like Figure 7 As shown, the first positioning element 13 of the two support mechanisms 1 can be located on the opposite side of the two crossbeams 5.
[0087] like Figure 8 As shown, the first positioning element 13 of the two support mechanisms 1 can be located on opposite sides of the two crossbeams 5.
[0088] In this way, the vehicle body can be moved by the lift, so that the first positioning parts 13 of the two support mechanisms 1 are located on the two crossbeams 5 opposite to each other or facing each other, thereby achieving the approximate positioning of the vehicle body on the support frame 11 in the front-rear direction, which is conducive to achieving stable load bearing on the vehicle body.
[0089] Especially when the support frame 11 has multiple fixing holes 115 and corresponding first fixing members 116, it is beneficial to quickly align the fixing holes 115 with the corresponding mounting holes on the chassis.
[0090] In some examples, reference Figure 1 As shown, the support mechanism 1 also includes two second positioning elements 14.
[0091] Both second positioning members 14 are connected to the support frame 11 and are located on opposite sides of the support frame 11 along the second direction 002. Figure 1 and combined Figure 3As shown, the two second positioning members 14 can be fixedly connected to the mounting plate 11124 on the corresponding side by means of bolts, welding, etc. In this configuration, the second direction 002 is perpendicular to the first direction 001. The second direction 002 can be the left or right direction of the vehicle body.
[0092] Both second positioning elements 14 have positioning planes 141, and the two positioning planes 141 are parallel to each other and located on opposite sides of the two second positioning elements 14. For example Figure 1 Combination Figure 5 As shown, the second positioning element 14 can be a flat plate, and one side surface of the flat plate can become the positioning plane 141.
[0093] In this way, phase distance measurement can be used on the production line. The distance can be calculated by measuring the phase difference between the transmitted and received signals on the positioning plane 141 to obtain the accurate position of the support mechanism 1 in the production line. Based on this, the lift can be controlled to move the vehicle body onto the support mechanism 1, so that the mounting hole and the fixing hole 115 can achieve precise positioning in the left and right directions.
[0094] In some examples, reference Figure 1 As shown, the support frame 11 also has at least two first positioning holes 117. The at least two positioning holes 117 correspond to a plurality of second positioning holes on the vehicle body, so that the rod-shaped positioning member can pass through the corresponding first positioning hole 117 and the second positioning hole on the vehicle body in sequence to achieve pre-positioning between the vehicle body and the support frame 11, thereby facilitating the fixing between the vehicle body and the support frame 11 by the first fixing member 116.
[0095] For example Figure 5 As shown, the first positioning hole 117 can be located on the connecting section 1122, and multiple first positioning holes 117 can be distributed at intervals along the second direction 002.
[0096] In some examples, reference Figure 9 As shown, the DKD vehicle body transfer device also includes a third positioning component 4. The third positioning component 4 is suitable for connection to a transport device. For example, the transport device can be an AGV, and the third positioning component 4 can be detachably connected to the AGV via bolts, snap-fits, or other means, facilitating separation between the AGV and the third positioning component 4 without affecting the AGV's application in other scenarios. The transport device can fix the support frame 11 using grippers, robotic arms, or other means.
[0097] Continue to refer to Figure 9 As shown, the third positioning member 4 has at least two first positioning structures 41. For example, in Figure 9In this embodiment, the third positioning element 4 may have two first positioning structures 41. However, in other possible examples, the third positioning element 4 may include three, four, or five first positioning structures 41, etc.
[0098] And such as Figure 9 As shown, at least two first positioning structures 41 can be distributed at intervals on the upper surface of the third positioning member 4.
[0099] The support frame 11 includes at least two second positioning structures, each corresponding to a first positioning structure 41, and the second positioning structure can be inserted into the corresponding first positioning structure 41 in the vertical direction.
[0100] For example, in the first positioning structure 41 and the second positioning structure, one can be a post and the other can be a hole, and the post can be inserted into the hole.
[0101] With the above configuration, when at least two second positioning structures are engaged with the corresponding first positioning structure 41, the relative positions of the support frame 11 and the transport device on the horizontal plane can be positioned. This allows the relative positions of the multiple fixing holes 115 of the two support frames 11 to be accurately determined, ensuring that when the transport device transports the DKD vehicle body transfer device, the fixing holes 115 in the DKD vehicle body transfer device are accurately aligned with the corresponding mounting holes on the vehicle body.
[0102] In some examples, reference Figure 1 As shown, when the support frame 11 includes a support portion 113, the support portion 113 is cylindrical and extends along a third direction 003. The third direction 003 is perpendicular to both the first direction 001 and the second direction 002. The first end of the support portion 113 is adapted to support the vehicle body. The third direction 003 can be the vertical direction of the vehicle body.
[0103] The columnar support 113 can provide accurate support for the corresponding position on the vehicle body, which helps to avoid interference between the support 113 and the vehicle body.
[0104] In some examples, reference Figure 2 As shown, when the support frame 11 includes a transverse connecting portion 111 and a transverse extension portion 112, at least two support portions 113 penetrate the corresponding transverse connecting portion 111 or transverse extension portion 112, making the second end of the support portion 113 a second positioning structure. The first positioning structure 41 is a hole, and the second end of the support portion 113 can be inserted into the corresponding hole. For example, in Figure 2 In the middle, the lateral extension 112 may have a connecting plate 1121 extending along the first direction 001, and the support 113 may pass through the corresponding connecting plate 1121, so that the second end of the support 113 becomes a second positioning structure.
[0105] In this way, at least two support parts 113 can position the handling device and the support frame 11, and at the same time support the vehicle body, which can reduce the complexity, weight and cost of the DKD vehicle body transfer device.
[0106] In some examples, such as Figure 2 As shown, a limit cap 1131 is provided on the top of the support part 113, which becomes the second positioning structure. The limit cap 1131 can prevent the support part 113 from falling off due to passing through the transverse connecting part 111 or the transverse extension part 112.
[0107] In some examples, reference Figure 10 As shown, each walking component 12 includes at least two walking wheels 121. Each of the at least two walking wheels 121 is connected to a support frame 11 and is located on opposite sides of the support frame 11 along the second direction 002. For example, the at least two walking wheels 121 can be respectively installed on opposite sides of the transverse connecting portion 111 of the support frame 11 along the second direction 002.
[0108] In this way, since each walking component 12 has two walking wheels 121, it is easy to move the corresponding support mechanism 1, and thus it is easy to move the support mechanism 1 to the storage location when idle.
