Description

[0002] Electric vehicles are becoming a popular travel choice due to their environmental and low-cost advantages. The power battery system is at its core and affects performance and endurance. With market competition and technological development, the transportation of power batteries faces great challenges. Whether it is the assembly of power batteries for new energy vehicles or the maintenance of power batteries for new energy vehicles, it is necessary to use a transfer vehicle to transport the power batteries. The existing power battery transfer vehicles have a lifting assist function, which is convenient for loading and unloading power batteries at different heights on the one hand; on the other hand, it can assist in the disassembly and assembly of power batteries. However, the existing transfer vehicles are basically the same, consisting of a load-bearing plate and a lifting part. The top of the load-bearing plate is mostly a flat plane. After the flat load-bearing plate on the top receives the power battery, the friction between the power battery and the load-bearing plate is relatively large. On the one hand, the position of the power battery is difficult to adjust, resulting in a random position of the carried power battery, an offset of the center of gravity of the transfer vehicle, and bumps during the movement of the transfer vehicle, with the risk of rollover and tilting; on the other hand, when the power battery is moved out of the transfer vehicle, tools such as forklifts or slings are required to move the power battery away, which requires the cooperation of multiple types of work and is time-consuming and labor-intensive; some load-bearing plates will increase sliding components and clamps such as rollers to reduce the friction between the power battery and the load-bearing plate and the fixation of the power battery, resulting in the need to adjust the roller group and clamps one by one during loading and unloading of the transfer vehicle, thereby improving the stability of the power battery during transportation and greatly extending the time for power battery transportation.

When the corner clamp rotates, the resetting restriction of the switching frame on the friction reduction part is released, thereby increasing the friction between the power battery and the storage table. At the same time, the switching frame can rise with the lifting structure, so that a single leg of the same corner clamp can rotate, so that the power battery can be moved out of the storage table.

After the power battery is clamped, the friction-reducing part is inserted into the storage table to increase the friction force during the transportation and lifting of the power battery, thereby improving the stability of the power battery during transportation. Before the power battery is moved out of the transportation carrier, the top of the friction-reducing part is pushed out of the storage table to reduce the friction between the power battery and the storage table again. At the same time, one of the legs of the corner clamp can be rotated to release the limit on the side of the power battery, so that the power battery can be moved out from the side of the transportation carrier. During the whole process, the resistance on the bottom of the power battery is adjusted by lifting and lowering the friction-reducing part, so that the transportation carrier can reduce the resistance on the bottom of the battery after receiving the power battery, and the power battery can be adjusted in position. After the power battery is clamped, the resistance on the bottom of the battery is increased to improve the stability of the power battery. When the power battery is moved out, the resistance on the bottom of the battery is reduced again, the limit on the side of the power battery is released, and the power battery is guided to be moved out.

DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] See also Figure 1-Figure 15 The present invention provides a technical solution: a heavy-duty new energy vehicle power battery transport vehicle with disassembly and assembly auxiliary function, comprising a storage platform 1, a base 11 is installed at the bottom of the storage platform 1 through a lifting frame 18: the height of the storage platform 1 is adjusted through the lifting frame 18, so that it can receive the power battery or lift the power battery to a suitable unloading platform; Also includes: The clamping arm 16 is provided at both ends of the storage platform 1 through synchronous reverse sliding of the linear driving structure 17; the linear driving structure 17 drives the clamping arm 16 to move away or approach synchronously; the driving clamping arm 16 moves synchronously by rotating the synchronous gear provided in the storage platform 1, and the synchronous gear is meshed with the driving clamping arm 16 at the same time; The corner clamp 3 disposed at the end of the clamp arm 16 is rotated. The corner clamp 3 is in a "V"-shaped structure, and the two legs can rotate relatively. The corner clamp 3 is rotated to contact the adjacent corners of the power battery. The corner clamp 3 is connected to the clamp arm 16 by a torsion spring for resetting the corner clamp 3. The corner clamp 3 moves synchronously with the clamp arm 16. When one of the legs of the corner clamp 3 contacts the power battery, the corner clamp 3 rotates as a whole, so that the other leg of the corner clamp 3 moves toward the adjacent side of the power battery. The same corner clamp 3 limits the two adjacent surfaces of the power battery. The friction reducing part 4 is elastically slidably arranged (elastic sliding refers to a sliding arrangement between two objects and connected by an elastic structure) in the storage table 1 to reduce the friction between the power battery and the storage table 1; A lifting structure 46 installed in the storage platform 1, the telescopic end of the lifting structure 46 can resist and push the friction reduction part 4 to extend out of the storage platform 1; The switching frame 5 is elastically slidably arranged in the storage table 1 through the bracket, and can switch between restricting the anti-friction part 4 from resetting and rising with the anti-friction part 4; The connecting structure 6 installed in the storage platform 1 releases the reset restriction of the friction reducing part 4 by the switching frame 5 when the corner clamp 3 rotates, thereby increasing the friction between the power battery and the storage platform 1; at the same time, the switching frame 5 can rise with the lifting structure 46, so that a single leg of the same corner clamp 3 can rotate, so that the power battery can be moved out of the storage platform 1; Specifically, when receiving the power battery, the storage table 1 is lifted to a suitable height by the lifting frame 18. At this time, the top of the friction-reducing part 4 is exposed from the storage table 1 and is reset by the switching frame 5. When the power battery falls on the storage table 1, the position of the power battery can be adjusted. When the position of the power battery is adjusted, the linear drive structure 17 drives the clamping arms 16 to approach each other, and the clamping arms 16 drive the corner clamps 3 to move toward the power battery. One of the legs of the corner clamps 3 contacts the power battery and pushes the power battery to move. When one of the legs of the corner clamps 3 on different clamping arms 16 contacts the power battery, the displacement of the power battery length square is determined, and the clamping arms 16 continue to be moved. The corner clamp 3 rotates, and one of the legs is moved. The power battery is restricted and cannot move along the clamp arm 16. The corner clamp 3 rotates around the hinge point between the clamp arm 16, and the other leg of the same corner clamp 3 moves toward the power battery. One of the two corner clamps 3 on the same clamp arm 16 will first contact the side of the power battery, and the corner clamp 3 pushes the power battery to move toward the other corner clamp 3 through the legs until both sides of the power battery are restricted by the two corner clamps 3 on the same clamp arm 16. The width of the power battery is fixed, and the power battery is received and positioned, so that the power battery is located in the center of the storage table 1, which can avoid the transfer vehicle center deviation, resulting in uneven force on each corner of the transfer vehicle, affecting the moving speed and steering difficulty of the transfer vehicle; When the corner clamp 3 rotates, the restriction of the switching frame 5 on the anti-friction part 4 is released through the connection structure 6, and the anti-friction part 4 descends under the gravity of the power battery, and the bottom of the power battery contacts the storage platform 1, and the contact area between the power battery and the storage platform 1 increases, thereby increasing the friction between the power battery and the storage platform 1. When the power battery is lifted or moved on the storage platform 1, the stability of the power battery is increased, thereby preventing the power battery from falling; After the power battery is fixed on the storage table 1, the storage table 1 is lowered to the lowest position and then the power battery is moved for transportation. When the power battery is moved to a suitable position, the storage table 1 is raised to be flush with the unloading platform, and the telescopic end of the lifting structure 46 rises. After the telescopic end contacts the bottom of the anti-friction part 4, the anti-friction part 4 rises along with the telescopic end of the lifting structure 46, and the top of the anti-friction part 4 extends out of the storage table 1 and slightly lifts the power battery, and the power battery is separated from the storage table 1. The anti-friction part 4 also drives the connection structure 6 to rise through the switching frame 5, so that a single leg of the same corner clamp 3 can rotate to move the power battery to the side of the transport vehicle, and the leg of the corner clamp 3 in contact with the side of the power battery can rotate to make way, so that the power battery can be moved out of the storage table 1, and the other leg of the corner clamp 3 guides the power battery, thereby improving the stability of the power battery when it is moved out of the transport vehicle.

[0017] In the present invention, by lifting the storage platform 1 to a suitable height to receive the power battery, the friction-reducing part 4 can reduce the resistance of the power battery when adjusting its position. After the power battery is clamped, the friction-reducing part 4 falls into the storage platform 1, increasing the friction force during the transportation and lifting of the power battery, and improving the stability of the power battery during transportation. Before the power battery is moved out of the transport carrier, the top of the friction-reducing part 4 is pushed out of the storage platform 1 to reduce the friction between the power battery and the storage platform 1 again. At the same time, one of the legs of the corner clamp 3 can be rotated to release the limit on the side of the power battery, and the power battery can be moved out from the side of the transport carrier. During the whole process, the friction-reducing part 4 is lifted and lowered to adjust the resistance on the bottom of the power battery, so that the transport carrier can reduce the resistance on the bottom of the battery after receiving the power battery, and the power battery can be adjusted in position. After the power battery is clamped, the resistance on the bottom of the battery is increased to improve the stability of the power battery. When the power battery is moved out, the resistance on the bottom of the battery is reduced again, the limit on the side of the power battery is released, and the power battery is guided to be moved out.

[0018] As a further solution of the present invention, the corner clamp 3 comprises: A rotating shaft 31, the rotating shaft 31 is rotatably disposed at the end of the clamping arm 16, and a "7"-shaped clearance groove 32 is opened on the side wall; A fixed support leg 33 fixed on the rotating shaft 31; A movable support leg 34 that slides on the side wall of the rotating shaft 31 through a connecting piece; A guide block 35 is slidably disposed in the clearance groove 32, and the guide block 35 is fixed to the movable support leg 34; A trigger member 36 axially slidably disposed on the side wall of the rotating shaft 31 through a key; Rotate the guide wheels 37 disposed on the fixed legs 33 and the movable legs 34; The rotation shaft 31 and the clamp arm 16, and the movable support leg 34 and the rotation shaft 31 are reset by torsion springs; Single angle clamp 3 motion states: Specifically, when the clamp arms 16 approach each other, the fixed legs 33 first contact the end of the power battery, and the fixed legs 33 are restricted by the power battery and cannot continue to move. The fixed legs 33 drive the rotating shaft 31 to rotate around the axis of the rotating shaft 31, and the rotating shaft 31 drives the trigger member 36 to rotate. The trigger member 36 releases the restriction on the resetting of the friction reducing part 4 by squeezing the connecting structure 6, and switches to be able to rise with the friction reducing part 4. The rotating shaft 31 drives the movable legs 34 to rotate through the vertical section of the yielding groove 32, and the movable legs 34 approach the side adjacent to the power battery until the movable legs 34 abut against the side of the power battery. The corner clamps 3 are used in combination to fix each corner of the power battery. When the connection structure 6 rises, the trigger member 36 drives the movable support leg 34 to rise, and the guide block 35 moves to the horizontal section of the clearance groove 32. When the power battery moves, the movable support leg 34 can rotate around the axis of the rotating shaft 31 to facilitate the removal of the power battery.

[0019] As a further solution of the present invention, the friction reduction part 4 includes a bottom plate 41 slidably arranged with the storage table 1, a boss 42 is installed on the top of the bottom plate 41, the boss 42 is arranged in a circular array, and a plurality of balls are rotatably arranged on the top, a sliding rod 44 with a "T"-shaped structure is fixed at the bottom of the bottom plate 41, an elastic member 45 is fixed between the sliding rod 44 and the storage table 1, and the switching frame 5 switches the upper surface and the lower surface of the bottom of the limiting sliding rod 44, which can limit the sliding rod 44 from descending and drive the connecting structure 6 to rise synchronously with the switching frame 5; As a further solution of the present invention, the switching frame 5 includes: A driving member 51, the driving member 51 is slidably disposed in the storage platform 1 through a bracket, and a tooth groove is provided on a side wall of the driving member 51; A lower limit frame 52 is elastically and laterally slidably arranged in the storage platform 1 through a bracket, and the lower limit frame 52 is used to limit the slide bar 44 from descending; A synchronous frame 53 is fixed to the driving member 51, and the bottom of the synchronous frame 53 is in conflict with the bottom of the connecting structure 6, and the lower limit frame 52 and the synchronous frame 53 alternately overlap with the movement trajectory of the bottom of the slide rod 44; Specifically, when the angle clamp 3 rotates, the driving member 51 moves, the lower limit frame 52 is separated from the bottom of the slide bar 44, and the friction reducing part 4 descends under the gravity of the power battery. At the same time, the synchronous frame 53 moves to the upper surface of the bottom of the slide bar 44. The synchronous frame 53 can rise synchronously when the slide bar 44 rises, and the synchronous frame 53 pushes the connecting structure 6 upward to make the trigger member 36 rise. It should be noted that the synchronization frame 53 is initially flush with the slide bar 44 , and after the slide bar 44 is lowered, it moves to the upper surface of the bottom of the slide bar 44 through the elastic structure or its own elastic force.

[0020] As a further solution of the present invention, the connection structure 6 comprises: A cross bar 61, which is elastically slidably disposed at the end of the clamp arm 16, and can rotate and move with the angle clamp 3, and the cross bar 61 can drive the movable support leg 34 to rise through the trigger member 36; The movable rack 62 at both ends is slidably arranged in the clamp arm 16 through elastic components, and the movable rack 62 moves to the side and can be engaged with the driving member 51 through the tooth groove; The fixed rack 63 fixed to the crossbar 61 is relatively displaced with the movable rack 62, driving the movable rack 62 to move sideways, and driving the driving member 51 to move synchronously through the movable rack 62; Specifically, when the angle clamp 3 rotates, the trigger member 36 rotates synchronously. After the trigger member 36 contacts the cross bar 61, the cross bar 61 moves along the movement direction of the clamp arm 16, and the movable rack 62 and the fixed rack 63 are relatively displaced. Under the action of the teeth, the fixed rack 63 moves away from the movable rack 62 and meshes with the driving member 51. The movable rack 62 and the fixed rack 63 are still in a meshing state, and the fixed rack 63 cannot move away from the movable rack 62. The fixed rack 63 moves with the movable rack 62 and drives the driving member 51 to move, so that the switching frame 5 can switch the restriction of the friction reduction part 4.

[0021] As a further solution of the present invention, the crossbar 61 is provided in a locking groove 64, and the locking groove 64 is "L" shaped; Specifically, the trigger member 36 rotates into the locking groove 64, which can drive the cross bar 61 to move. When the cross bar 61 rises, the locking groove 64 first moves relative to the trigger member 36. After the trigger member 36 moves to the bottom of the locking groove 64, the trigger member 36 moves accordingly, and the movable support leg 34 can rotate. At the same time, the locking groove 64 limits the rotation of the trigger member 36. The trigger member 36 limits the rotation of the rotating shaft 31 and the fixed support leg 33 through the key, which can prevent the fixed support leg 33 from changing its position, resulting in failure of the guide of the power battery and affecting the removal of the power battery.

[0022] As a further solution of the present invention, the linear drive structure 17 is a clamping cylinder, and both ends of the clamping cylinder are connected to the storage platform 1 and the clamping arm 16 respectively.

[0023] As a further solution of the present invention, a flip table 12 is arranged between the lifting frame 18 and the storage table 1, a universal joint 13 and a flip cylinder 14 are arranged between the flip table 12 and the lifting frame, and a translation cylinder 15 is installed between the flip table 12 and the storage table 1; this allows the transfer vehicle to be adjusted in multiple directions and also allows the storage table 1 to be translated, so that the transfer vehicle can be suitable for use in more complex occasions.
