Description

Technical Field

[0001] The present application relates to the technical field of transport devices, and in particular to a transport vehicle body and a transport vehicle. Background Art

[0002] The models of existing transport vehicles are basically fixed. When transporting goods, the overall volume of the transport vehicle is fixed and cannot be changed, so the types of goods transported by the transport vehicle are relatively single and the total amount of goods transported cannot be changed, making the transport vehicle not very suitable for transporting goods. Summary of the invention

[0003] In view of this, it is necessary to provide a transport body and a transport vehicle, which are intended to be able to change the shape of the transport body so that the transport body can transport goods of different sizes and improve applicability.

[0004] An embodiment of the present application provides a transport vehicle body, including a cargo platform, a connecting beam and a suspension device, the cargo platform including a frame, a fixed frame and a first driving member, the end of the frame is movably disposed on the fixed frame, the first driving member is connected to the frame, and is used to drive the frame to move relative to the fixed frame, the connecting beam is disposed on the frame, the suspension device includes a cantilever and a second driving member, the cantilever is movably disposed on the connecting beam, one end of the second driving member is connected to the cantilever, and the other end is connected to the connecting beam, and is used to drive the cantilever to move on the connecting beam.

[0005] With the above transport body, the cargo platform can adjust its size according to different cargoes, and can widen its distance along the moving direction of the frame, so that it can be suitable for different cargoes. At the same time, the cantilever in the suspension device can move on the connecting beam, and can also widen its size. Both the cargo platform and the suspension device can adjust their sizes, so that the transport body can be suitable for cargoes of different sizes, thereby improving the applicability of the transport body.

[0006] In a possible implementation, the frame includes a first crossbeam and a second crossbeam, the first crossbeam and the second crossbeam are hinged, and the second crossbeam is movably disposed on the fixing frame.

[0007] The first cross beam and the second cross beam are hingedly arranged so that the second cross beam can rotate relative to the first cross beam, so that the second cross beam can be connected to different external structures during the process of connecting with other structures.

[0008] In a possible implementation, the fixing frame includes a locking member, and the locking member is used to lock the second crossbeam.

[0009] The second cross beam is locked by the locking member to prevent the second cross beam from moving during use of the transport body and causing unstable placement of the goods.

[0010] In one possible implementation, the cargo platform includes two frames, two fixed frames and two first driving frames, the two frames are symmetrically arranged, the two fixed frames are symmetrically arranged, the two ends of each frame are movably arranged on the fixed frames, two first driving members are arranged on one of the fixed frames, and each driving member is connected to one of the frames.

[0011] By arranging two frames and two fixing frames, and making the two frames and the two fixing frames roughly form a closed structure, the goods can be better carried.

[0012] In one possible implementation, the cantilever includes a guide member and a mounting member, the mounting member is used to connect the tire, and the guide member is used to flexibly cooperate with the connecting beam.

[0013] The cantilever and the tire are connected by arranging a mounting piece, so that the cantilever can drive the wheel body to move, and at the same time, the cantilever is connected to the connecting beam through a guide piece, so that the movement of the cantilever can be guided.

[0014] In one possible implementation, the guide member has a guide hole, and the guide hole is used for the connecting beam to be inserted so that the cantilever can move along the extension direction of the connecting beam.

[0015] The guide hole is connected to the connecting beam in a form such that the cantilever can be displaced relative to the transport vehicle body along the extension direction of the connecting beam.

[0016] In a possible implementation, the mounting member includes a connecting bracket and a wheel axle, the connecting bracket is hinged to the guide member, and the wheel axle is hinged to an end of the connecting bracket away from the guide member.

[0017] The connecting bracket is hinged to the guide member, and a buffer device can be added between the connecting bracket and the guide member to provide buffering when driving on a bumpy road.

[0018] In one possible implementation, the suspension device also includes a steering member and a rotation locking member, the wheel axle is hinged to the connecting bracket through the steering member, the rotation locking member is arranged on the cantilever, and is used to lock the relative position of the wheel axle and the connecting bracket, and one end of the second driving member is connected to the steering member, and the other end is used to connect to the connecting beam.

[0019] The steering member is used for wheel steering, and the second driving member drives the steering member to realize the movement of the suspension device on the connecting beam. The same driving member is used to complete wheel steering and wheel expansion, but when the wheel is expanded, the rotational freedom of the steering member and the connecting bracket needs to be limited by rotating the locking member, so that the driving member can only drive the suspension device to move on the connecting beam.

[0020] In a possible implementation, the rotation locking member includes a telescopic member, which is fixed to the connecting bracket and has a movable end capable of abutting against the steering member.

[0021] The telescopic member achieves relative fixation of the steering member and the connecting bracket by abutting against the steering member. When the steering member and the connecting bracket are relatively fixed, the cantilever can be driven to approach or move away from the vehicle body through the telescopic movement of the driving member.

[0022] A transport vehicle comprises a vehicle body and a transport vehicle body as described in any one of the above, wherein the transport vehicle body is connected to the vehicle body.

[0023] The transport vehicle adopts the above-mentioned transport body and can adjust its own size according to the size of the goods when transporting different goods, so that the transport body can adapt to different goods, thereby improving the applicability of the transport vehicle.

[0072] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0073] It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a central component at the same time.

The terms "top", "bottom", "upper", "lower", "left", "right", "front", "back", and similar expressions used herein are for illustrative purposes only.

[0074] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0075] An embodiment of the present application provides a transport vehicle body, including a cargo platform, a connecting beam and a suspension device, the cargo platform including a frame, a fixed frame and a first driving member, the end of the frame is movably disposed on the fixed frame, the first driving member is connected to the frame, and is used to drive the frame to move relative to the fixed frame, the connecting beam is disposed on the frame, the suspension device includes a cantilever and a second driving member, the cantilever is movably disposed on the connecting beam, one end of the second driving member is connected to the cantilever, and the other end is connected to the connecting beam, and is used to drive the cantilever to move on the connecting beam.

[0076] With the above transport body, the cargo platform can adjust its size according to different cargoes, and can widen its distance along the moving direction of the frame, so that it can be suitable for different cargoes. At the same time, the cantilever in the suspension device can move on the connecting beam, and can also widen its size. Both the cargo platform and the suspension device can adjust their sizes, so that the transport body can be suitable for cargoes of different sizes, thereby improving the applicability of the transport body.

[0077] The following will further describe the embodiments of the present application in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0078] See also Figure 1 In order to better explain the structure in this application, the above and below, left and right, and front and back coordinates will be used for explanation. A transport vehicle body 100 provided in this application includes a cargo platform 10, a connecting beam 20, and a suspension device 30. The connecting beam 20 is arranged on the frame 11, and the suspension device 30 is movably arranged on the connecting beam 20. The size of the cargo platform 10 can be adjusted according to the size of the cargo, and the suspension device 30 can also adjust the spacing, so that the transport vehicle body 100 has a large adjustment space to cope with cargoes of different sizes (not shown).

[0079] See also Figure 2 The cargo platform 10 includes a frame 11, a fixed frame 12 and a first driving member 13. The end of the frame 11 is movably disposed on the fixed frame 12. The first driving member 13 is disposed on the fixed frame 12 and connected to the frame 11, and is used to drive the frame 11 to move relative to the fixed frame 12.

[0080] In one embodiment, the cargo platform 10 includes two frames 11, two fixed frames 12 and two first driving members 13. The two frames 11 are symmetrically arranged along the front-to-back direction, and the two fixed frames 12 are symmetrically arranged along the left-to-right direction. The two ends of each frame 11 are movably arranged in the two fixed frames 12, respectively. Two first driving members 13 are arranged on one of the fixed frames 12, and each first driving member 13 is connected to one of the frames 11.

[0081] The frame 11 is generally in a U-shaped structure, and further, the frame 11 includes a first crossbeam 111 and a second crossbeam 112, the first crossbeam 111 and the second crossbeam 112 are generally vertically arranged, and the first crossbeam 111 and the second crossbeam 112 are hinged, so that the first crossbeam 111 and the second crossbeam 112 can rotate relative to each other. Specifically, the first crossbeam 111 is arranged along the front-to-back direction, the second crossbeam 112 is arranged along the left-to-right direction, and the second crossbeam 112 is movably arranged in the fixing frame 12.

[0082] The frame 11 includes two second cross beams 112 . The two second cross beams 112 are respectively disposed at two ends of the first cross beam 111 and are respectively connected to one of the fixing frames 12 .

[0083] By hingedly connecting the first cross beam 111 and the second cross beam 112, the second cross beam 112 can rotate relative to the first cross beam 111. When the transport body 100 is connected to a vehicle head (not shown), the second cross beam 112 can rotate to adapt to the vehicle head, thereby improving the applicability of the transport body 100.

[0084] See also Figure 2 The fixing frame 12 includes a body 121, and the body 121 is roughly in the shape of a cuboid, where "roughly" means looking like, not absolutely in the shape of a cuboid. The body 121 is provided with a mounting groove 122, and the mounting groove 122 penetrates the body 121 in the left-right direction. The end of the second crossbeam 112 is disposed in the mounting groove 122 and can move in the mounting groove 122. It can be understood that in other embodiments, two mounting grooves 122 can also be provided on the body 121, and each mounting groove 122 corresponds to one second crossbeam 112.

[0085] In one embodiment, the fixing frame 12 further includes a locking member 123, which is disposed on the body 121 and can extend from the outside of the body 121 to the installation slot 122. The locking member 123 is used to lock the second cross beam 112 to prevent the second cross beam 112 from moving during the use of the transport body 100, thereby causing unstable placement of the goods. Further, the locking member 123 is a locking bolt, and a plurality of fixing holes are provided at intervals on the second cross beam 112. The locking member 123 is adapted to the fixing holes to lock the second cross beam 112 and the body 121.

[0086] It is understandable that, in other embodiments, the locking member 123 is not limited thereto, and may be replaced by other structures, for example, by a spring buckle. When the fixing hole on the second beam 112 is moved to a position corresponding to the spring buckle, the spring buckle may protrude into the fixing hole.

[0087] In one embodiment, the fixing frame 12 further includes a connecting portion 124 , and the connecting portion 124 is disposed on the body 121 . The fixing frame 12 can be connected to an external structure, such as a front of a vehicle, through the connecting portion 124 .

[0088] See also Figure 2The first driving member 13 is arranged on the fixing frame 12. Further, two first driving members 13 are symmetrically arranged on the fixing frame 12. In one embodiment, the first driving member 13 is a hydraulic cylinder. The first driving member 13 includes a first piston rod 131 and a first hydraulic cylinder 132. One end of the first piston rod 131 is arranged in the first hydraulic cylinder 132, and the other end is fixed to the second cross beam 112. The first hydraulic cylinder 132 is arranged on the fixing frame 12.

[0089] When the transport body 100 needs to carry different goods, for example, large goods, the first driving member 13 can drive the frame 11 to move in a direction away from the fixed frame 12, so that the distance between the two frames 11 increases, thereby increasing the area of ​​the rectangular structure formed by the frame 11 and the fixed frame 12, so that large goods can be placed on the cargo platform 10 (not shown).

[0090] It is understandable that, in other embodiments, the first driving member 13 may also be replaced by other structures having equivalent functions or effects.

[0091] The first driving member 13 is a hydraulic cylinder, which has a strong locking property. When the first driving member 13 can be used to lock the frame 11, the locking member 123 can be omitted.

[0092] In one implementation, in order to better support the cargo, a plurality of support rods are provided between the two first beams 111 . The plurality of support rods are arranged in parallel to assist the cargo platform 10 in carrying the cargo together, so as to enhance the strength of the cargo platform 10 in carrying the cargo.

[0093] Please refer to Figure 1 The connecting beam 20 is disposed on the first cross beam 111 and is vertically disposed to the first cross beam 111 along the left-right direction, and the suspension device 30 is disposed on the connecting beam 20 .

[0094] The connecting beam 20 is provided with a slide groove 21 , and the cantilever 31 can be clamped in the slide groove 21 . The slide groove 21 is used to limit the cantilever 31 to prevent the suspension device 30 from rotating when moving on the connecting beam 20 .

[0095] See also Figure 1 and Figure 3 The suspension device 30 includes a cantilever 31 and a second driving member 32. The cantilever 31 is movably arranged on the connecting beam 20. One end of the second driving member 32 is connected to the cantilever 31, and the other end is connected to the connecting beam 20, and is used to drive the cantilever 31 to move on the connecting beam 20.

[0096] Please participate Figure 1 , Figure 3 and Figure 4 The cantilever 31 includes a guide member 311 and a mounting member 312. The guide member 311 is provided with a guide hole O, into which the connecting beam 20 is inserted, and the guide member 311 can move along the extension direction of the connecting beam 20 to achieve the movable connection of the suspension device 30. The mounting member 312 is connected to the guide member 311, and a wheel 40 is mounted on the mounting member 312, and the rolling of the wheel 40 on the road surface drives the transport body 100 to move.

[0097] One end of the second driving member 32 is connected to the cantilever 31, and the other end is connected to the connecting beam 20. The cantilever 31 is driven by the second driving member 32 to move along the extension direction of the connecting beam 20, so that the cantilever 31 is relatively close to or away from the cargo platform 10, driving the wheel 40 to be relatively close to or away from the cargo platform 10, thereby expanding or reducing the support area of ​​the transport body 100.

[0098] The wheels 40 support the entire transport body 100 on the road surface. The position of the wheels 40 is also the support position of the transport body 100. All wheels 40 together enclose a support area. When the support area is too small, the overall center of gravity of the transport body 100 is easy to move out of the support area, making the transport body 100 easy to tip over. However, when the support area is too large, it is not conducive to the car passing through a narrow area. This transport body 100 can move relative to the cargo platform 10 via the suspension device 30 to achieve a change in the support area to adapt to various situations during transportation.

[0099] The guide member 311 includes a sleeve 3111, a guide hole O is formed in the middle of the sleeve 3111, the cross-sectional shape of the connecting beam 20 is roughly square, and the two slide grooves 21 of the connecting beam 20 form an arc surface, and the cross-sectional shape of the guide hole O is the same as the cross-sectional shape of the connecting beam 20. That is, the plane part of the inner wall of the guide hole O forms a stop surface P, and the stop surface P fits with the slide groove 21 of the connecting beam 20 to prevent the guide member 311 from rotating around the connecting beam 20. In other forms, the cross-sectional shape of the guide hole O can also be set to a semicircular, round crown, hexagonal, etc. shape, as long as it is non-circular, a stop surface P can be formed to prevent the guide member 311 from rotating around the connecting beam 20.

[0100] The guide member 311 further includes two installation frames 3112, one of which is disposed at one end of the sleeve 3111 close to the cargo platform 10, and the other of which is disposed at one end of the sleeve 3111 away from the cargo platform 10. The installation frame 3112 includes two half frames connected by bolts, which are assembled and connected to be sleeved on the outside of the connecting beam 20, and a hinge space is formed between the two installation frames 3112.

[0101] The mounting member 312 includes a connecting bracket 3121, one end of which is inserted into the hinge space, and a hinge shaft 3113 passes through a mounting frame 3112, the connecting bracket 3121 and another mounting frame 3112 in sequence to realize the hinge connection between the guide member 311 and the mounting member 312, and the hinge shaft 3113 is parallel to the extension direction of the connecting beam 20.

[0102] In one embodiment, the cantilever 31 includes two mounting members 312, and the two mounting members 312 are symmetrically arranged on both sides of the mounting frame 3112. The two mounting members 312 are connected by a hydraulic cylinder, and the hydraulic cylinder provides a buffering force, so that the two mounting members 312 can rotate around the connecting axis when subjected to external force, and are buffered by the buffering force of the hydraulic cylinder.

[0103] The mounting member 312 further includes a wheel axle (not shown) disposed at one end of the connecting bracket 3121 away from the guide member 311, through which the wheel axle is used to mount the wheel 40. To facilitate the steering of the wheel 40, the suspension device 30 includes a steering member 313, through which the wheel axle is hinged to the connecting bracket 3121.

[0104] Specifically, the steering member 313 includes a hinge column 3131, and a parallel first clamping plate and a second clamping plate are arranged at one end of the connecting bracket 3121 away from the guide member 311. The hinge column 3131 is arranged between the first clamping plate and the second clamping plate, and the two ends are rotatably connected to the first clamping plate and the second clamping plate respectively. The hinge column 3131 is arranged perpendicular to the hinge shaft 3113, and the wheel axle is arranged on the side of the hinge column 3131 away from the cargo platform 10. By rotating the hinge column 3131 relative to the connecting bracket 3121, the angle between the wheel axle and the cargo platform 10 changes, and then the angle between the wheel 40 on the wheel axle and the cargo platform 10 can change.

[0105] The steering member 313 further includes a connecting arm 3132 extending in a direction deviating from the wheel axle, and one end of the second driving member 32 away from the cargo platform 10 is hinged to the connecting arm 3132. Since there is still a certain position conflict between the connecting bracket 3121 and the second driving member 32, in order to facilitate the installation of the second driving member 32, a clearance hole 3122 is further provided on the connecting bracket 3121 for the second driving member 32 to pass through the connecting bracket 3121.

[0106] The second driving member 32 is a hydraulic cylinder. The cantilever 31 can be pushed away from the cargo platform 10 by extending the second driving member 32, and the cantilever 31 can be pulled closer to the cargo platform 10 by shortening the second driving member 32. Since the connection position between the second driving member 32 and the steering member 313 is eccentrically arranged relative to the wheel axle, when the cantilever 31 is driven closer to or away from the cargo platform 10 by the second driving member 32, the steering member 313 and the connecting bracket 3121 need to be relatively locked to prevent the wheel 40 from turning when the second driving member 32 is extended or shortened.

[0107] The cantilever 31 device also includes a rotation locking member 314, through which the relative rotation of the steering member 313 and the connecting bracket 3121 can be locked or unlocked. The rotation locking member 314 includes a telescopic member, and the telescopic member formed by a cylinder is fixed on the connecting bracket 3121, and the movable end of the telescopic member is arranged toward the hinge column 3131. When the telescopic member is extended, its movable end abuts against the hinge column 3131, so that the hinge column 3131 and the connecting bracket 3121 are locked, that is, the steering member 313 and the connecting bracket 3121 are locked. When the telescopic member is shortened, its movable end leaves the hinge column 3131, and the hinge column 3131 restores the rotational freedom, so that the steering member 313 can rotate relative to the connecting bracket 3121. Therefore, when the wheel 40 needs to be expanded or retracted, the telescopic member is first extended to lock the steering member 313 and the connecting bracket 3121, and then the driving member is extended or shortened to achieve the cantilever 31 being relatively away from or close to the cargo platform 10.

[0108] In addition to being able to drive the cantilever 31 to move along the extension direction of the connecting beam 20, the second driving member 32 can also drive the wheel 40 to deflect to achieve the steering of the transport body 100. When the second driving member 32 is required to drive the wheel 40 to deflect, it is necessary to fix the relative position of the cantilever 31 and the connecting beam 20. In order to fix the relative position of the cantilever 31 and the connecting beam 20, a first positioning hole is provided on the guide member 311, and a plurality of second positioning holes arranged at intervals along the extension direction of the connecting beam 20 are provided on the connecting beam 20. The connecting beam 20 and the cantilever 31 can be relatively fixed by passing the positioning bolt 3115 through the first positioning hole and the corresponding second positioning hole. When the connecting beam 20 and the cantilever 31 are relatively fixed, the second driving member 32 can drive the wheel 40 to deflect relative to the cargo platform 10, thereby achieving the steering of the transport body 100.

[0109] Specifically, the cargo platform 10 includes a steering assembly 14 for steering the transport vehicle body 100. The steering assembly 14 includes a pull rod 141 and a rocker arm 142. The rocker arm 142 is rotatably arranged on the pull rod 141. One end of the second driving member 32 is hinged to the cantilever 31, and the other end is hinged to the rocker arm 142. Four rocker arms 142 are arranged on a pull rod 141, and each rocker arm 142 corresponds to a wheel 40. When the pull rod 141 is pulled, the four rocker arms 142 can be driven to move synchronously at the same time, so as to achieve synchronous deflection of the four wheels 40 on this side. The cargo platform 10 includes two steering assemblies 14, which are symmetrically arranged on the left and right sides of the cargo platform 10 and are linked to each other, so that when the four wheels 40 on one side of the displacement are deflected, the four wheels 40 on the other side of the displacement are synchronously deflected.

[0110] See also Figure 5 When the transport vehicle 100 needs to travel on a narrow road, or when the transport vehicle 100 transports smaller transport objects, the positioning bolts 3115 on the connecting beam 20 and the guide member 311 are removed, and the steering member 313 and the connecting bracket 3121 are locked by rotating the locking member 314. The second driving member 32 is shortened to pull the cantilever 31 to move toward the cargo platform 10, and the positioning bolts 3115 are inserted into the first positioning hole and the corresponding second positioning hole to fix the position of the connecting beam 20 and the guide member 311. The rotating locking member 314 is unlocked to enable the steering member 313 and the connecting bracket 3121 to rotate relative to each other. At this time, the wheels 40 are supported at a position close to the vehicle body, forming a smaller support area, but it is convenient to avoid obstacles on the road. On a narrow road, all wheels 40 can be attached to the road surface to form support, and the steering member 313 and the connecting bracket 3121 can rotate relative to each other without affecting the steering of the transport vehicle.

[0111] See also Figure 6 When the transport body 100 needs to travel on a wide road, the positioning bolts 3115 on the connecting beam 20 and the guide member 311 are removed, and the steering member 313 and the connecting bracket 3121 are locked by the rotating locking member 314. The second driving member 32 is extended to push the cantilever 31 to move away from the cargo platform 10. The positioning bolts 3115 are inserted into the first positioning hole and the corresponding second positioning hole to fix the position of the connecting beam 20 and the guide member 311. The rotating locking member 314 is unlocked to enable the steering member 313 and the connecting bracket 3121 to rotate relative to each other.
