Description

Technical Field

[0001] This utility model relates to the field of transporter technology, and in particular to a transporter and its holding mechanism. Background Technology

[0002] Existing gripping car handling devices often use gear transmission mechanisms or worm gear mechanisms for their gripping mechanisms. However, both gear transmission mechanisms and worm gear mechanisms require high precision and are difficult to manufacture, resulting in high costs.

[0003] Meanwhile, when using gear transmission, the drive motor is often located at the bottom of the gear, resulting in a larger thickness of the entire transporter. Consequently, the thickness of other related equipment will also increase, leading to higher overall costs.

[0004] When using worm gear transmission, each gripping arm is equipped with a motor to drive the worm gear mechanism for clamping action. The large number of motors increases the number of potential failure points and raises maintenance costs. Utility Model Content

Detailed Implementation

[0048] Typical embodiments embodying the features and advantages of this utility model will be described in detail in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0049] In the description of this application, it should be understood that, in the embodiments shown in the accompanying drawings, the indications of direction or positional relationships (such as up, down, left, right, front, and back) are merely for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. These descriptions are appropriate when these elements are in the positions shown in the accompanying drawings. If the description of the positions of these elements changes, these directional indications also change accordingly.

[0050] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0051] According to one aspect of this application, a holding mechanism is provided for holding a wheel.

[0052] The following detailed description of specific embodiments of the holding mechanism of this application, in conjunction with the accompanying drawings, provides a comprehensive overview.

[0053] Figure 1 This is a schematic diagram of one of the states of the holding mechanism in this embodiment. Figure 2 This is a schematic diagram of another state structure of the holding mechanism in this embodiment.

[0054] refer to Figure 1 and Figure 2 The holding mechanism 110 includes a mounting base 1, a drive assembly 3, two holding assemblies 2, and two linkage assemblies 4. The two holding assemblies 2 are arranged at opposite ends of the mounting base 1. Each holding assembly 2 includes two spaced-apart holding members, each hinged to the mounting base 1. The two linkage assemblies 4 are arranged one-to-one with the two holding assemblies 2. The drive assembly 3 is mounted on the mounting base 1. The drive assembly 3 includes a drive member 31 and a moving member 32. The moving member 32 is located between the two holding assemblies 2, and the drive member 31 is driven to drive the moving member 32. Each linkage assembly 4 includes a linkage member 41, which is hinged to the moving member 32, the mounting base 1, and the two holding members of the corresponding holding assembly 2. The two linkage members 41 can rotate as the moving member 32 moves, thereby driving the corresponding two holding members to rotate towards each other to hold the wheel or to rotate in the opposite direction to release the wheel.

[0055] In this application, the two gripping members of each gripping assembly 2 are hinged to the mounting base 1, allowing each gripping member to rotate relative to the mounting base 1. Furthermore, a linkage member 41 is provided for each gripping assembly 2, with the two gripping members of each gripping assembly 2 hinged to the corresponding linkage member 41, allowing each gripping member and the corresponding linkage member 41 to rotate relative to each other. Simultaneously, the two linkage members 41 are hinged to the moving member 32, which can move under the drive of the driving member 31. This design not only allows the two linkage members 41 to rotate simultaneously and synchronously with the movement of the moving member 32, but also, during the rotation of the linkage members 41 with the moving member 32, each linkage member 41 can drive the two correspondingly arranged gripping members to rotate relative to the linkage members 41, so that the two gripping members of each gripping assembly 2 can rotate towards each other relative to the mounting base 1 to grip the wheel, or rotate in the opposite direction to release the wheel.

[0056] In other words, the holding mechanism 110 in this application uses a moving part 32 that is simultaneously linked with two linkage parts 41 to achieve the rotational holding function of the holding part. Since the moving part 32 is located between the two linkage parts 41, this design facilitates the improvement of the structural compactness of the holding mechanism 110. At the same time, compared with the gear transmission mechanism or worm gear mechanism in the prior art, the linkage component 4 in this application has lower processing difficulty and precision requirements. Furthermore, this application uses a driving part 31 as a power source, which reduces the number of failure points and thus reduces manufacturing and maintenance costs.

[0057] In this embodiment, the mounting base 1 includes a base plate, a top plate 11, and two side plates 12. The base plate and the top plate 11 are spaced vertically apart. The two side plates 12 are located on opposite sides of the base plate, and each side plate 12 is connected between the base plate and the top plate 11. The base plate, the top plate 11, and the two side plates 12 together form a mounting cavity.

[0058] For ease of description, it is hereby defined that the distribution direction of the two side plates 12 of the mounting base 1 is the first direction, and the direction perpendicular to the first direction in the same horizontal plane is the second direction.

[0059] Specifically, the side plate 12 extends along the second direction. The top plate 11 extends outward beyond the side plate 12 at both ends along the second direction.

[0060] In this embodiment, the two holding components 2 are arranged at opposite ends of the mounting base 1. Specifically, the two holding components 2 are arranged at both ends of the mounting base 1 along the second direction.

[0061] Each holding assembly 2 includes two holding members spaced apart, and each holding member is hinged to the mounting base 1.

[0062] Specifically, each holding component 2 has two holding members, namely a first holding member 21 and a second holding member 22, which are distributed at intervals along a first direction.

[0063] The first holding member 21 includes a first holding arm 212 and a first connecting arm 211 connected together. The first connecting arm 211 is hinged to the mounting base 1 via a first connecting shaft 51. Exemplarily, the first connecting arm 211 extends into the mounting cavity and is distributed vertically at intervals with the top plate 11 and the bottom plate. The first connecting shaft 51 passes through the top plate 11 and the first connecting arm 211, and is fixedly connected to the top plate 11, while being rotatably connected to the first connecting arm 211 to achieve the hinge connection between the first connecting arm 211 and the top plate 11. The design of the first connecting arm 211 being distributed vertically at intervals with the top plate 11 and the bottom plate avoids interference from the top plate 11 and the bottom plate on the rotation of the first connecting arm 211, thus ensuring the smooth rotation of the first connecting arm 211.

[0064] In other embodiments, the first connecting shaft 51 may be rotatably connected to the top plate 11, and the first connecting shaft 51 may be fixedly connected to the first connecting arm 211, so that the first connecting arm 211 can rotate relative to the mounting base 1.

[0065] In this embodiment, the first connecting shaft 51 can be rotatably connected to the first connecting arm 211 through a bearing, so as to improve the smoothness and stability of the rotation of the first connecting arm 211.

[0066] In this embodiment, the first connecting arm 211 is bent. The first connecting arm 211 includes a first connecting portion 2111 and a first bent portion 2112. The first connecting portion 2111 is hinged to the mounting base 1 via a first connecting shaft 51. When the holding mechanism 110 is in the holding state, the first bent portion 2112 is located inside the first connecting portion 2111 in a second direction. Specifically, the included angle of the bend of the first connecting arm 211 is an obtuse angle.

[0067] In other embodiments, the first connecting arm 211 may also be linear, etc.

[0068] In this embodiment, the first holding arm 212 includes a first support portion 2121 and at least two first roller sets. The first support portion 2121 is connected to the outer end of the first connecting arm 211 along the second direction and extends outward beyond the mounting base 1 to avoid the mounting base 1 interfering with the rotation of the first holding arm 212, thereby ensuring the smooth rotation of the first holding member 21 relative to the mounting base 1.

[0069] At least two first roller sets are spaced apart on the first support 2121. Specifically, adjacent roller sets are spaced apart both vertically and in the first direction. This design allows at least two first roller sets of the first holding member 21 to be adapted to the shape of the wheel, so that each first roller set can contact the outer periphery of the wheel. This increases the contact area between the first holding arm 212 and the wheel, thereby reducing damage to the wheel during holding and reducing the risk of the wheel accidentally detaching from the holding assembly 2.

[0070] Each first roller group is rotatably connected to the first support portion 2121, allowing each first roller group to rotate freely relative to the first support portion 2121. This free rotation of the first roller groups reduces friction when the wheel contacts the first roller group, thus minimizing damage to the wheel. For example, each first roller group may also include two first rollers 2122, spaced apart along the length of the first support portion 2121 and rotatably connected to it. This design improves the freedom and flexibility of rotation of each first roller 2122 when in contact with the wheel. In other embodiments, each first roller group may include one first roller 2122 extending along the length of the first support portion 2121. Alternatively, each first roller group may include three or more first rollers 2122 spaced apart along the length of the first support portion 2121.

[0071] The second holding member 22 includes a second connecting arm 221 and a second holding arm 222. The second connecting arm 221 is hinged to the mounting base 1 via a second connecting shaft 52. The specific connection relationship between the second connecting arm 221, the second connecting shaft 52 and the mounting base 1 is described above in the relevant description of the connection relationship between the first connecting arm 211, the first connecting shaft 51 and the mounting base 1, and will not be repeated here.

[0072] The second connecting shaft 52 and the first connecting shaft 51 are spaced apart along the first direction to ensure the synchronicity of the rotation of the first connecting arm 211 and the second connecting arm 221 and the consistency of the rotation range.

[0073] In this embodiment, the second connecting arm 221 is bent. The second connecting arm 221 includes a second connecting portion 2211 and a second bent portion 2212. The second connecting portion 2211 is hinged to the mounting base 1 via a second connecting shaft 52. When the holding mechanism 110 is in the holding state, the second bent portion 2212 is located on the side of the second connecting portion 2211 that is opposite to the first connecting arm 211 in a first direction. Specifically, the included angle of the bend of the second connecting arm 221 is an acute angle.

[0074] In other embodiments, the second connecting arm 221 may also be linear, etc.

[0075] In this embodiment, the second holding arm 222 is symmetrically arranged with the first holding arm 212, and the second holding arm 222 cooperates with the first holding arm 212 to hold the wheel. The second holding arm 222 includes a second support portion 2221 and at least two second roller sets. Each second roller set may include at least two second rollers 2222 arranged at intervals, or it may include one second roller 2222. Regarding the distribution of at least two second roller sets and the structure of each second roller set, as well as the related settings of the second support portion 2221, please refer to the description of the related settings of the first roller set and the first support portion 2121 above, and it will not be repeated here.

[0076] The drive assembly 3 is mounted on the mounting base 1, and the drive assembly 3 includes a drive component 31 and a moving component 32. The moving component 32 is located between the two holding components 2, and the drive component 31 is driven to the moving component 32. The drive component 31 is used to drive the moving component 32 to move.

[0077] Exemplarily, the drive element 31 may include a drive body 311 and a drive shaft 312 drivenly connected to the drive body 311. The drive body 311 is mounted on one side plate 12, and the output end of the drive body 311 is arranged towards the other side plate 12 along a first direction. One end of the drive shaft 312 passes through the side plate 12 near the drive body 311 and is connected to the drive body 311, and the other end is connected to the top plate 11 or the side plate 12 away from the drive body 311 via a hinge seat 33. The drive shaft 312 is rotatably connected to the hinge seat 33. The drive body 311 is used to drive the drive shaft 312 to rotate. A movable member 32 is sleeved on the outer periphery of the drive shaft 312 and threadedly connected to the drive shaft 312. Specifically, when the drive shaft 312 rotates, under the action of the thread, the drive shaft 312 can rotate relative to the movable member 32, and the movable member 32 moves along the drive shaft 312. In contrast to the prior art where the motor needs to be placed at the bottom of the gear when using a gear transmission mechanism, the configuration of the drive component 31 in this embodiment can also reduce the thickness of the holding mechanism 110 to a certain extent.

[0078] In other embodiments, the drive body 311 can also drive the drive shaft 312 to extend or retract. In this case, the movable member 32 is fixedly connected to the drive shaft 312 and moves as the drive shaft 312 extends or retracts.

[0079] In this embodiment, two linkage components 4 are arranged in a one-to-one correspondence with two holding components 2. Each linkage component 4 includes a linkage member 41, which is hinged to the moving member 32, the mounting base 1, and the two holding members of the corresponding holding component 2. The two linkage members 41 can rotate as the moving member 32 moves, thereby driving the two corresponding holding members to rotate in opposite directions to hold the wheel or to rotate in the opposite direction to release the wheel.

[0080] The linkage 41 is arranged in the mounting cavity of the mounting base 1. The linkage 41 includes a body 411, a first linkage part 412, a second linkage part 413 and a third linkage part 414.

[0081] The main body 411 is hinged to the mounting base 1. Specifically, the main body 411 is hinged to the top plate 11 via the third connecting shaft 53. For the specific connection method, please refer to the above description of the first connecting arm 211 being hinged to the mounting base 1 via the first connecting shaft 51, which will not be repeated here.

[0082] The first linkage part 412, the second linkage part 413, and the third linkage part 414 are distributed at intervals on the outer periphery of the main body 411, with the first linkage part 412 located between the second linkage part 413 and the third linkage part 414. A first included angle, which is acute, is formed between the first linkage part 412 and the second linkage part 413. A second included angle, which is also acute, is formed between the first linkage part 412 and the third linkage part 414.

[0083] In this embodiment, the first linkage part 412 is hinged to the moving part 32. Specifically, the linkage assembly 4 also includes a first connecting member 42. One end of the first connecting member 42 is hinged to the first linkage part 412, allowing relative rotation between the first connecting member 42 and the first linkage part 412; the other end of the first connecting member 42 is hinged to the moving part 32, allowing relative rotation between the first connecting member 42 and the moving part 32. In this embodiment, with the body 411 of the linkage member 41 hinged to the mounting base 1 to fix the rotation center of the linkage member 41, the moving part 32 and the linkage member 41 are linked by the first connecting member 42. This allows the linkage member 41 to rotate via the first connecting member 42 during the movement of the moving part 32 in the first direction. Furthermore, this arrangement better accommodates the displacement caused by relative rotation between the moving part 32 and the linkage member 41.

[0084] Specifically, the first linkage part 412 and the first connecting member 42 are hinged together by a first hinge shaft 54. The first connecting member 42 includes two first connecting rods. The two first connecting rods are located on the upper and lower sides of the end of the first linkage part 412, and the first hinge shaft 54 ​​passes through the two first connecting rods and the first linkage part 412 to realize the hinge connection between the two first connecting rods and the first linkage part 412.

[0085] The first hinge shaft 54 ​​can be hinged to the first linkage part 412 through a bearing to improve the smoothness and stability of the relative rotation between the first linkage part 412 and the first connecting member 42.

[0086] The first connecting member 42 and the movable member 32 are connected by a second hinge shaft 55. For example, the movable member 32 is located between the two first connecting members 42, and the second hinge shaft 55 passes through the two first connecting members 42 and the movable member 32 to realize the hinge connection between the two first connecting members 42 and the movable member 32.

[0087] The second hinge shaft 55 can be hinged to the moving part 32 through a bearing to improve the smoothness and stability of the relative rotation between the first connecting part 42 and the moving part 32.

[0088] The second linkage part 413 is hinged to the first holding member 21. Specifically, the linkage assembly 4 also includes a second connecting member 43. One end of the second connecting member 43 is hinged to the second linkage part 413, allowing relative rotation between the second connecting member 43 and the second linkage part 413; the other end of the second connecting member 43 is hinged to the first holding member 21, allowing relative rotation between the second connecting member 43 and the first holding member 21. In this embodiment, with the body 411 of the linkage member 41 hinged to the mounting base 1 to fix the rotation center of the linkage member 41, and the first holding member 21 hinged to the mounting base 1 to fix the rotation center of the first holding member 21, the first holding member 21 and the linkage member 41 are linked by the second connecting member 43. This allows the first holding member 21 to rotate via the second connecting member 43 during the rotation of the linkage member 41 driven by the moving member 32. Furthermore, this arrangement better accommodates the displacement caused by the relative rotation between the second holding member 22 and the linkage member 41.

[0089] For example, the first holding member 21 and the second connecting member 43 are hinged together by the first hinge pin 56, and the second connecting member 43 and the second linkage part 413 are hinged together by the third hinge pin 58. The connection methods between the second connecting member 43 and the first holding member 21 and the second linkage part 413 are similar to the configuration methods between the first connecting member 42 and the moving member 32 and the first linkage part 412 described above, and will not be repeated here.

[0090] The first hinge shaft 56 and the first connecting shaft 51 are spaced apart. Specifically, the first hinge shaft 56 is hinged to the first bent portion 2112 of the first holding member 21. Since the first connecting portion 2111 is hinged to the mounting base 1 through the first connecting shaft 51, and an included angle is formed between the first connecting portion 2111 and the first bent portion 2112, this ensures that while the linkage member 41 and the first holding member 21 are linked through the second connecting member 43, mutual interference can be avoided when relative rotation occurs between the second connecting member 43 and the linkage member 41, between the linkage member 41 and the mounting base 1, between the second connecting member 43 and the first holding member 21, and between the first holding member 21 and the mounting base 1, thus ensuring the smooth rotation of the second connecting member 43, the linkage member 41, and the first holding member 21.

[0091] In this embodiment, the second connector 43 is arc-shaped, and the concave surface of the second connector 43 faces away from the second holding member 22. This can avoid interference between the second connector 43 and the first holding member 21 during rotation, thereby ensuring the smooth rotation of the second connector 43 and the first holding member 21.

[0092] In other embodiments, the second connector 43 may also be linear.

[0093] The third linkage part 414 is hinged to the second holding member 22. Specifically, the linkage assembly 4 also includes a third connecting member 44. One end of the third connecting member 44 is hinged to the third linkage part 414, allowing relative rotation between the third connecting member 44 and the third linkage part 414; the other end of the third connecting member 44 is hinged to the second holding member 22, allowing relative rotation between the third connecting member 44 and the second holding member 22. In this embodiment, with the body 411 of the linkage member 41 hinged to the mounting base 1 to fix the rotation center of the linkage member 41, and the second holding member 22 hinged to the mounting base 1 to fix the rotation center of the second holding member 22, the second holding member 22 and the linkage member 41 are linked by the third connecting member 44. This allows the second holding member 22 to rotate via the third connecting member 44 during the rotation of the linkage member 41 driven by the moving member 32. Furthermore, this arrangement better accommodates the displacement caused by the relative rotation between the third holding member and the linkage member 41.

[0094] For example, the second holding member 22 and the third connecting member 44 are hinged together by the second hinge pin 57, and the third connecting member 44 and the third linkage part 414 are hinged together by the fourth hinge pin 59. The connection methods between the second connecting member 43 and the second holding member 22 and the third linkage part 414 are similar to the configuration methods between the first connecting member 42 and the moving member 32 and the first linkage part 412 described above, and will not be repeated here.

[0095] The second hinge shaft 57 and the second connecting shaft 52 are spaced apart. Specifically, the second hinge shaft 57 is hinged to the second bent portion 2212 of the second holding member 22. Since the second connecting portion 2211 is hinged to the mounting base 1 through the second connecting shaft 52, and an included angle is formed between the second connecting portion 2211 and the second bent portion 2212, this ensures that while the linkage member 41 and the second holding member 22 are linked through the third connecting member 44, mutual interference can be avoided when relative rotation occurs between the third connecting member 44 and the linkage member 41, between the linkage member 41 and the mounting base 1, between the third connecting member 44 and the second holding member 22, and between the second holding member 22 and the mounting base 1, thus ensuring the smooth rotation of the third connecting member 44, the linkage member 41, and the second holding member 22.

[0096] As can be seen from the above, in the holding mechanism 110 of this embodiment, a moving member 32 is linked with two first connecting members 42, two linkage members 41, two second connecting members 43 and two third connecting members 44, and a driving member 31 is used as a power source to drive the moving member 32 to move. This enables the synchronous rotation of the two holding members of each holding component 2 in opposite directions, so as to synchronously realize the action of the two holding components 2 holding or releasing the wheel. The above design facilitates the improvement of the structural compactness of the holding mechanism 110. At the same time, compared with the gear transmission mechanism and worm gear transmission mechanism in the prior art, the linkage structure composed of the above components in this application has lower processing difficulty and precision requirements. Furthermore, since the number of power sources is small, the number of failure points is also reduced, thereby reducing manufacturing and maintenance costs.

[0097] According to another aspect of this application, a transporter 100 is also provided for transporting automobiles.

[0098] Figure 3 This is a schematic diagram of the structure of the transporter 100 in this embodiment.

[0099] refer to Figure 3 The transporter 100 includes a vehicle body and at least two traveling mechanisms and two holding mechanisms 110 as described above, all mounted on the vehicle body.

[0100] In this embodiment, the vehicle body includes two spaced-apart frames 120. Specifically, the two frames are spaced apart along a first direction and correspond to the front and rear ends of the vehicle being transported.

[0101] Figure 4 This is a schematic diagram of the carrier 100 holding a car in this embodiment.

[0102] refer to Figure 3 and Figure 4 In this embodiment, each frame 120 is provided with a corresponding holding mechanism 110, and the two holding mechanisms 110 correspond one-to-one with the front and rear wheels of the car.

[0103] For example, each frame 120 includes a first frame and a second frame, which are arranged on both sides of the mounting base 1 of the holding mechanism 110 along the first direction and are fixed one-to-one with the two side plates 12 of the mounting base 1.

[0104] At least two walking mechanisms and two holding mechanisms 110 are distributed at intervals along the length of the vehicle body.

[0105] This embodiment uses two walking mechanisms as an example for explanation. Specifically, each frame 120 is equipped with a walking mechanism, and each walking mechanism is used to drive the corresponding frame 120 to move. Since each frame 120 is equipped with a corresponding holding mechanism 110, each frame 120 and its supporting walking mechanism and holding mechanism 110 can constitute an independent part, and the transporter 100 is composed of two independent parts, so that the two independent parts can act independently of each other.

[0106] Each walking mechanism includes two sets of walking wheels 131 and a power unit 132. The two sets of walking wheels 131 are arranged on both sides of the holding mechanism 110 along a first direction to balance the support for the frame 120 and improve the stability of the transporter 100's movement. Each set of walking wheels 131 includes two walking wheels 131, which are spaced apart on the frame 120 and rotatably connected to the frame 120 via axles. The power unit 132 drives the walking wheels 131 to rotate, thereby enabling the transporter 100 to move.

[0107] For example, the number of power components 132 can be one. In this case, the power component 132 is driven connected to one of the sets of traveling wheels 131. Specifically, the power component 132 may include a power element 1321, a coupling 1322, a driving wheel 1323, and a driven wheel 1324. The two axles of the traveling wheel set 131 are connected by the coupling 1322 to connect the two traveling wheels 131 into one unit, enabling the two traveling wheels 131 to rotate synchronously. The power element 1321 is mounted on the frame 120 with its output shaft extending in a second direction. The output shaft of the power element 1321 is driven connected to the driving wheel 1323. The driving wheel 1323 and the driven wheel 1324 are connected by a connecting belt. The driven wheel 1324 is sleeved on the coupling 1322 and fixed to the coupling 1322. The power element 1321 drives the driving wheel 1323 to rotate, thereby driving the coupling 1322 to rotate, thus realizing the rotation of the traveling wheel 131. The connecting belt can be a track, chain, or other similar material.

[0108] In this embodiment, the power component 1321 is mounted on the frame 120 via a connecting seat 133. The connecting seat 133 is movably connected to the frame 120, allowing the connecting seat 133 to move relative to the frame 120 in a first direction. This drives the drive wheel 1323 to move in the first direction, thereby adjusting the tension of the connecting belt.

[0109] In other embodiments, the power assembly 132 may omit the coupling 1322, drive wheel 1323, driven wheel 1324, and connecting belt. In this case, the power component 1321 adopts a dual-output shaft configuration, with the two output shafts driving and connecting one-to-one with the two traveling wheels 131. Alternatively, each traveling wheel 131 may be provided with a single-axis power component 1321.

[0110] The transporter 100 also includes a wheelbase adjustment mechanism 140, which is connected between the two frames 120 to connect the two frames 120 into one unit, and the wheelbase adjustment mechanism 140 is used to adjust the distance between the two frames 120.

[0111] Figure 5 This is a schematic diagram of the wheelbase adjustment mechanism 140 in this embodiment.

[0112] refer to Figure 3 and Figure 5 The wheelbase adjustment mechanism 140 includes at least two hinged arms 141, which are connected end-to-end in sequence. The two outermost hinged arms 141 are hinged one-to-one with the two frames 120, allowing adjacent hinged arms 141 to rotate relative to each other and extend or retract, thereby adjusting the distance between the two frames 120 to accommodate various vehicle models with different front and rear wheelbases. In practical applications, since the two independent parts of the transporter 100 are structurally independent, adaptive wheelbase adjustment can be achieved by controlling at least one independent part of the transporter 100 to move to the corresponding relative distance. Furthermore, since the two independent parts of the transporter 100 need to be connected by cables, the wheelbase adjustment mechanism 140 can also function as a cable tray for cable routing and stabilization, preventing cables from sagging and scraping against the ground. Additionally, anti-detachment strips can be installed on the hinged arms 141 to further ensure that cables do not accidentally come loose. Because of the limit on the maximum wheelbase by the wheelbase adjustment mechanism 140, the maximum distance between the two independent parts of the carrier 100 can be limited to protect the cable from damage caused by excessive stretching.

[0113] Figure 6 yes Figure 5 Enlarged structural diagram at point A in the middle.

[0114] refer to Figure 5 and Figure 6 The wheelbase adjustment mechanism 140 also includes two rotating components 142, and the articulated arm 141 is hinged to the frame 120 through the rotating components 142.

[0115] Specifically, the rotating assembly 142 includes a base 1421, a reversing member 1422, a first rotating shaft 1423, and a second rotating shaft 1424. The base 1421 is fixedly connected to the frame 120, and the reversing member 1422 is hinged to the base 1421 via the first rotating shaft 1423, allowing the reversing member 1422 to rotate relative to the base 1421. The articulated arm 141 is hinged to the reversing member 1422 via the second rotating shaft 1424, allowing the articulated arm 141 to rotate relative to the reversing member 1422.

[0116] Furthermore, the first rotating shaft 1423 and the second rotating shaft 1424 are perpendicular and do not intersect. The first rotating shaft 1423 extends along the second direction, so that the reversing member 1422 can drive the folding arm 141 to rotate upward or downward along the first rotating shaft 1423. This is to accommodate the deformation or other abnormal damage to the wheelbase adjustment mechanism 140 caused by the relative height difference or relative obliqueness between the two frames 120 when the transporter 100 passes through gaps, steps, etc. during its movement.

[0117] The second pivot 1424 extends vertically. This design enables the folding arm 141 to rotate on the horizontal plane, thereby allowing the two folding arms 141 to automatically open and close, thus adapting to vehicles with different wheelbases for the front and rear wheels.

[0118] As can be seen from the above technical solution, this utility model has at least the following advantages and positive effects:

[0119] In this application, the two gripping members of each gripping assembly are hinged to the mounting base, allowing each gripping member to rotate relative to the mounting base. Furthermore, each gripping assembly is provided with a linkage member, with the two gripping members of each assembly hinged to their respective linkage members, enabling relative rotation between the gripping members and their corresponding linkage members. Simultaneously, the two linkage members are hinged to a moving member, which can move under the drive of a driving member. This design not only allows the two linkage members to rotate simultaneously and synchronously with the movement of the moving member, but also, during the rotation of the linkage members along with the moving member, each linkage member can drive the two correspondingly arranged gripping members to rotate relative to the linkage members, so that the two gripping members of each gripping assembly can rotate towards each other relative to the mounting base to grip the wheel, or rotate in the opposite direction to release the wheel.

[0120] In other words, the holding mechanism in this application uses a method where one moving part is simultaneously linked with two linkage parts to achieve the rotational holding function of the holding part. Since the moving part is located between the two linkage parts, this design facilitates the improvement of the structural compactness of the holding mechanism. At the same time, compared with the gear transmission mechanism or worm gear mechanism in the prior art, the linkage component in this application has lower processing difficulty and precision requirements. Furthermore, this application uses a single driving part as the power source, which reduces the number of failure points, thereby reducing manufacturing and maintenance costs.

Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims.
