As shown in fig. 1-4, an embodiment of the present invention discloses a transportation vehicle, which includes a vehicle body 110, wheels 130, a limiting member, a winding and unwinding mechanism, and a resetting member 700.

The body 110 is a main structure of the transportation vehicle, and is generally made of hard materials such as metal, etc. to ensure that the body 110 has high structural strength, and other components in the transportation vehicle can be mounted on the body 110, and the shape and size of the body 110 are not limited here.

The wheel 130 is rotatably mounted on the vehicle body 110, specifically, the wheel 130 may be mounted on the vehicle body 110 through a rotary connecting member such as a bearing, and the wheel 130 may be connected to a driving mechanism such as a driving motor, so that the wheel 130 can drive the entire transportation vehicle to move under the driving of the driving mechanism. The number of wheels 130 may be three, four or more, and the arrangement of the wheels 130 may be determined according to the specific number of wheels 130.

The limiting member is mounted on the vehicle body 110, and the limiting member can move relative to the vehicle body 110, optionally, the movement form between the limiting member and the vehicle body 110 may be a linear relative movement, or may be a rotational movement. Furthermore, the limiting member may be installed near the wheel 130 to ensure that the limiting member can move to a position attached to the wheel 130. Specifically, the limiting member may be a rod-shaped or plate-shaped structural member, and the limiting member may be movably mounted on the vehicle body 110 through a structure in which the structural member such as a slider or a pin and the like is matched with the sliding groove, so as to ensure that the limiting member can move relative to the vehicle body 110 under the action of the winding and unwinding mechanism and the reset member 700, and respectively enter a clamping state and an opening state, and respectively achieve the purpose of clamping the wheel 130 and releasing the wheel 130.

The winding and unwinding mechanism comprises a driving part 510 and a transmission part 520, the driving part 510 specifically comprises a rotating motor, or the driving part 510 further comprises a speed reducer, and the speed reducer is connected with the rotating motor so as to improve the driving stability of the rotating motor. The transmission member 520 can be wound around the driving member 510, and specifically, the transmission member 520 can be a structure member such as a transmission chain, a transmission belt or a transmission rope, which can be wound around the driving member 510 and provide a tensile driving force. The transmission member 520 is connected to the limiting member, and particularly, one end of the transmission member 520 is fixed to the limiting member, so that the driving member 510 can drive the limiting portion to move relative to the vehicle body 110 through the transmission member 520 under the condition that the driving member 510 works.

During the operation of the transportation vehicle, the driving member 510 drives the limiting member through the transmission member 520, and also drives the limiting member to stretch the restoring member 700. In detail, by rolling up the transmission member 520, the length of the portion of the transmission member 520 between the driving member 510 and the limiting member is shortened, so that the driving member 510 applies a pulling force to the limiting member through the transmission member 520, and the limiting member moves relative to the vehicle body 110, so that the position of the limiting member connected to the reset member 700 is far away from the position of the reset member 700 connected to the vehicle body 110, and the reset member 700 is in a stretching state. After the limiting member moves relative to the vehicle body 110, the limiting member can be attached to the wheel 130, so that the wheel 130 and the limiting member rub against each other, at this time, the driving member 510 continues to operate to continuously provide a driving torque to the limiting member, and the limiting member can maintain a state of applying an acting force to the wheel 130 under the action of the driving torque, so as to prevent the wheel 130 from rotating relative to the vehicle body 110.

The restoring member 700 is a structural member having an elastic capability, which may be a rubber rope, for example, or the restoring member 700 is a spring. One end of the reset member 700 is connected to the vehicle body 110, and the other end is connected to the limiting member. As described above, in the process that the driving element 510 drives the limiting element to move through the transmission element 520, the resetting element 700 is stretched to enable the resetting element 700 to be in a stretching state, and then, under the condition that the driving element 510 is in a closing state, the limiting element loses a driving acting force, the resetting element 700 recovers deformation under the elastic action of itself, and then the limiting element is driven to move in the opposite direction, so that the limiting element is separated from the wheel 130, and the wheel 130 can continue to rotate under the action of the driving mechanisms such as the driving motor.

The embodiment of the application provides a transport vehicle, which comprises a vehicle body 110, wheels 130, a limiting part, a winding and unwinding mechanism and a resetting part 700, wherein the winding and unwinding mechanism comprises a driving part 510 and a transmission part 520 which are in transmission connection, the transmission part 520 is connected with the limiting part, so that, when the driving member 510 is operated, the limiting member can be driven by the transmission member 520 to move, and the limiting member is driven to stretch the restoring member 700, and the limiting member can be attached to the wheel 130 after the action, so that the limiting member can limit the wheel 130 to continue rotating, thereby providing the deceleration and braking functions for the wheels 130 of the transport vehicle, preventing the transport vehicle from continuing to move under the action of inertia, ensuring that the transport vehicle can be stopped at the preset position as accurately as possible, thereby promote the transportation efficiency and the effect of goods etc. reduce or even eliminate because of the transport vechicle can't in time brake and stop the adverse effect that the work produced to goods rotation.

Further, the limiting member may be rotatably connected to the vehicle body 110, in which case the driving member 510 may drive the limiting member to rotate through the transmission member 520, so as to attach the limiting member to the wheel 130, and also contact the limiting member with a supporting surface, such as the ground, that provides a supporting function for the transportation vehicle, in which case the limiting member may not only attach to the wheel 130, but also limit the rotation of the wheel 130. Specifically, the limiting member may be rotatably connected to the vehicle body 110 through a rotating shaft or the like.

Through adopting above-mentioned technical scheme, when locating part and wheel 130 laminate, the locating part still contacts with the holding surface, the holding surface is the plane or the curved surface that supports the transport vechicle, contact through locating part and holding surface, make the locating part can also rub each other with the holding surface, make on the transport vechicle structure except wheel 130 also can contact with the holding surface each other, strengthen the ability that keeps relative stillness between transport vechicle and the holding surface, prevent the relative holding surface of transport vechicle from sliding, and then, when the transport vechicle has set actuating mechanism such as arm, even if actuating mechanism can move relative transport vechicle, also be difficult to make the relative holding surface of transport vechicle remove, be favorable to promoting the stability of transport vechicle.

Correspondingly, when the driving part 510 drives the limiting part to rotate through the transmission part 520, the limiting part can also stretch the reset part 700, and then under the condition that the driving part 510 stops working, the reset part 700 can provide reset acting force for the limiting part under the action of restoring self deformation, and then the limiting part is separated from the wheel 130 and the supporting surface, so that the wheel 130 can rotate, and further the transportation vehicle can restore the motion capability.

As mentioned above, the position-limiting element may be a plate-shaped or rod-shaped structural element, in another embodiment of the present application, optionally, the position-limiting element includes a first arm 310 and a second arm 320, the first arm 310 and the second arm 320 are both rotatably connected to the vehicle body 110, the first arm 310 and the second arm 320 are respectively disposed on two opposite sides of the wheel 130, and the driving element 510 can drive the first arm 310 and the second arm 320 to both engage with the wheel 130 and both contact with the supporting surface.

Specifically, the first arm 310 and the second arm 320 may be rod-shaped or plate-shaped structures, and may be disposed at an interval or disposed in a cross manner, and the first arm 310 and the second arm 320 are ensured to be attached to the wheel 130, so as to improve the fixed effect of the wheel 130, and further prevent the wheel 130 from rotating. Moreover, the first arm 310 can contact with the supporting surface on one side of the wheel 130, and the second arm 320 can contact with the supporting surface on the other side of the wheel 130, so as to prevent the wheel 130 from sliding forwards and backwards at the same time, and further reduce the probability of the sliding and shaking of the transportation vehicle. In order to further improve the limiting effect of the limiting part on the sliding condition of the transport vehicle, the attaching area between the limiting part and the supporting surface can be increased, so that the friction force between the limiting part and the supporting surface is increased, and the anti-skidding effect of the limiting part is further improved.

The first arm 310 and the second arm 320 may be provided with a reset member 700 between the vehicle body 110 and the first arm 310 and the second arm 320, so as to ensure that the first arm 310 and the second arm 320 can be reset under the action of the reset member 700 when the driving member 510 stops working, that is, the first arm 310 and the second arm 320 are separated from the wheel 130 and the supporting surface, and ensure that the wheel 130 can normally rotate under the driving of the driving mechanism, so as to drive the whole transportation vehicle to move. The two restoring members 700 may have the same structure to reduce the difficulty of spare parts and the difficulty of installation, and the installation positions of the two restoring members 700 may be determined according to the positions of the first supporting arm 310 and the second supporting arm 320, which is not limited herein.

Alternatively, the first arm 310 and the second arm 320 are driven by two driving members 510 respectively, one driving member 510 may be disposed on a side of the first arm 310 away from the second arm 320, the other driving member 510 may be disposed on a side of the second arm 320 away from the first arm 310, and the two driving members 510 are connected to the first arm 310 and the second arm 320 respectively through a transmission member 520, and under the driving of the two driving members 510, the first arm 310 and the second arm 320 can be rotated towards each other, so as to rotate from opposite sides of the wheel 130 to positions close to the wheel 130, and finally to be attached to the wheel 130, and to contact with the supporting surface.

In another embodiment of the present application, the first arm 310 and the second arm 320 are optionally driven by a single driving member 510, in which case, the transportation vehicle further includes a flexible sleeve 530, and the flexible sleeve 530 can be bent, but the dimension between any two positions in the flexible sleeve 530 along the axial direction thereof is not changed by being squeezed or the like. That is, the linear distance between any two locations in the flexible sleeve 530 may vary, but the path or dimension of the two locations along the extending direction of the flexible sleeve 530 may not vary due to the deformation of the sleeve. The flexible sleeve 530 may be formed by spirally winding a steel material, and the steel material may be covered with a flexible material such as rubber.

Also, the first arm 310 and the second arm 320 are disposed to intersect, and the first arm 310 is connected to the transmission member 520. The position of the actuator 510 may be determined by the arrangement of the first arm 310 and the second arm 320. Specifically, a mounting member such as a hinge shaft 150 may be provided on the vehicle body 110, and both the first arm 310 and the second arm 320 may be rotatably mounted on the hinge shaft 150, so that the first arm 310 and the second arm 320 are disposed to intersect and are rotatably connected to the vehicle body 110. The first arm 310 may be divided into two parts, with the hinge shaft 150 as a boundary, the first part being connected to the transmission member 520, and the second part being attached to the wheel 130 and contacting the support surface. In the above embodiment, in order to ensure that the first arm 310 can be attached to the wheel 130 under the action of the driving element 510, as shown in fig. 2, the driving element 510 may be disposed on a side of the first portion of the second arm 320, which is away from the first portion of the first arm 310, and correspondingly, the second portion of the first arm 310 is located between the wheel 130 and the driving element 510, and the second portion of the second arm 320 is located on a side of the wheel 130, which is away from the driving element 510. Furthermore, in the process of rolling the driving element 520 by the driving element 510, the first portion of the first arm 310 may move toward the driving element 510, and the second portion of the first arm 310 is driven to move away from the driving element 510, so that the second portion of the first arm 310 moves toward the wheel 130, and finally can be attached to the wheel 130 and contact with the supporting surface.

At the same time, the flexible sleeve 530 is disposed between the driving member 510 and the second arm 320, so as to ensure that the second arm 320 can move relative to the wheel 130 along with the driving member 510. Specifically, the two opposite ends of the flexible sleeve 530 may directly abut against the second support arm 320 and the driving element 510, or abutting structures may be fixedly disposed on both the driving element 510 and the second support arm 320, and the two opposite ends of the flexible sleeve 530 may abut against the abutting structures, respectively, so as to reduce the difficulty in mounting the flexible sleeve 530. In the above situation, as the driving element 510 winds up the driving element 520, the size of the portion of the driving element 520 located between the first arm 310 and the driving element 510 is reduced, as mentioned above, since the total length of the flexible sleeve 530 does not change, the sleeve can support the second arm 320 while the driving element 510 winds up the driving element 520 and drives the first arm 310 to rotate, so that the second arm 320 rotates together, and the second portion of the second arm 320 can also rotate in the direction close to the wheel 130, thereby achieving the purpose of driving the first arm 310 and the second arm 320 simultaneously through one driving element 510.

In the above embodiment, only one driving member 510 is needed to drive the first arm 310 and the second arm 320 at the same time, which can reduce the production cost of the transportation vehicle, reduce the installation space occupied by the device on the transportation vehicle, and reduce the assembly cost of the transportation vehicle; in addition, the first support arm 310 and the second support arm 320 are driven by one driving member 510, so that the synchronism of the first support arm 310 and the second support arm 320 can be improved, and the anti-skid and anti-shaking limiting effect of the whole transport vehicle can be further improved.

Optionally, the transportation vehicle further includes a mounting frame 540, the mounting frame 540 is fixed on the vehicle body 110, the driving element 510 may be disposed between the mounting frame 540 and the vehicle body 110, the mounting frame 540 is provided with a first through hole, the driving element 520 penetrates the first through hole to be in transmission connection with the driving element 510, the first end of the flexible sleeve 530 abuts against the mounting frame 540, so that the mounting frame 540 provides a limiting effect for the flexible sleeve 530, and in the working process of the driving element 510, the mounting frame 540 does not move relative to the vehicle body 110, so that the abutting of the flexible sleeve 530 against the mounting frame 540 may be improved in stability, and the installation difficulty of the flexible sleeve 530 may be reduced. The specific configuration of the mounting bracket 540 may be determined according to the actual configuration and size of the driving member 510, the driving member 510 may be disposed in the mounting bracket 540, and the first through-hole may be disposed in a portion of the mounting bracket 540 between the driving member 510 and the first arm 310, so that the overall extension path of the driving member 520 is relatively smooth. The size of the first through hole is larger than that of the transmission member 520, and the size of the first through hole is smaller than that of the flexible sleeve 530, so that the flexible sleeve 530 can be reliably supported on the mounting frame 540, and the driving force can be increased for the second support arm 320 under the action of the driving member 510.

As described above, the first arm 310 and the second arm 320 are arranged to intersect and are both hinged to the hinge shaft 150 fixed to the vehicle body 110. Optionally, the first arm 310 is integrally located on one side of the second arm 320. In order to achieve better synchronization and more uniform stress between the first arm 310 and the second arm 320, optionally, the first arm 310 includes a first hinge section 311 and a first joint section 312, the second arm 320 includes a second hinge section 321 and a second joint section 322, and the first hinge section 311 and the second hinge section 321 are distributed along the axial direction of the hinge shaft 150 and are hinged on the hinge shaft 150; moreover, the first attaching section 312 extends towards one side of the second hinge section 321 from the first hinge section 311, the second attaching section 322 extends towards one side of the first hinge section 311 from the second hinge section 321, and both the first attaching section 312 and the second attaching section 322 can be attached to the wheel 130 under the action of the driving member 510 and contact with the supporting surface. Under the condition of adopting above-mentioned technical scheme, in the axial of hinge 150, can make first laminating section 312 and second laminating section 322 set up relatively centrally, and then make the two action points on wheel 130 more symmetrical, promote the effect between first support arm 310 and second support arm 320 and the wheel 130, further promote the antiskid of first support arm 310 and second support arm 320 and prevent shaking the effect. Of course, the first hinge segment 311 and the second hinge segment 321 may be configured to be arc-shaped structures, so that the first hinge segment 311 and the second hinge segment 321 may also be attached to the wheel 130, thereby further improving the limiting effect on the wheel 130.

Specifically, along the axial direction of the hinge shaft 150, the size of the first attaching section 312 and the size of the second attaching section 322 can be the same, and the size of the first attaching section 312 is equal to the sum of the sizes of the first hinge section 311 and the second hinge section 321 in the above direction, so that the stability of the overall structure of the first support arm 310 and the second support arm 320 is better, and it can be ensured that both the first support arm 310 and the second support arm 320 can provide a reliable limiting effect for the wheel 130. In addition, the hinge shaft 150 may be disposed right above the axle of the wheel 130, that is, the hinge shaft 150 is disposed on the side of the axle of the wheel 130 away from the supporting surface, in which case, the first arm 310 and the second arm 320 may be symmetrically disposed, so as to further improve the consistency of the limiting effect of the two on the wheel 130, and improve the anti-slip and anti-sway effect provided for the transportation vehicle.

In the above situation, further, a second through hole may be formed in the second support arm 320, and the transmission element 520 may be connected to the first support arm 310 through the second through hole, and the second end of the flexible sleeve 530 abuts against the second support arm 320, so that the transmission element 520 may extend more smoothly, and the relative action relationship between the transmission element 520, the flexible sleeve 530 and the second support arm 320 may be more reliable, so that the bonding effect and the bonding reliability between the first support arm 310 and the wheel 130 and between the second support arm 320 and the wheel 130 may be better.

In order to improve the limiting effect provided by the limiting element on the wheel 130, optionally, the limiting element includes an arc-shaped segment, and under the driving action of the driving element 510, the arc-shaped segment can be attached to the wheel 130 and contact with the supporting surface, so as to increase the area of the portion where the limiting element and the wheel 130 are attached to each other, and improve the positioning effect of the arc-shaped segment on the wheel 130; moreover, as the driving element 510 drives the limiting element to rotate, at least a portion of the arc segment can be embedded between the wheel 130 and the supporting surface, so that the wheel 130 is held by the limiting element, and the limiting element is also in contact with the supporting surface, thereby further preventing the wheel 130 from moving relative to the supporting surface.

Specifically, the end of the arc segment may form a wedge structure, so that the end of the arc segment can be embedded in the space between the wheel 130 and the supporting surface along with the rotation of the limiting member. As described above, the retaining member may include the first arm 310 and the second arm 320, in which case, the first arm 310 and the second arm 320 may each include an arc-shaped segment, and the first arm 310 and the second arm 320 may be inserted between the wheel 130 and the supporting surface from opposite sides of the wheel 130, respectively, to prevent the wheel 130 from sliding forward or backward. More specifically, the first arm 310 may include a first hinge section 311 and a first attaching section 312, and the second arm 320 may include a second hinge section 321 and a second attaching section 322, so that at least a portion of the first hinge section 311 and the first attaching section 312 may be both arc-shaped structural members, and at least a portion of the second hinge section 321 and the second attaching section 322 may be both arc-shaped structural members, which may increase an area of a portion of the limiting member that can be attached to the wheel 130, thereby further improving a limiting effect on the wheel 130.

Further, the arc segment may be provided with a fitting plane 310a, and the fitting plane 310a may be fitted to the supporting surface to increase the contact area between the limiting member and the supporting surface, and further improve the limiting effect of the limiting member on the wheel 130. Specifically, the shape and the area of the fitting plane 310a can be determined according to actual conditions, and are not limited herein, and correspondingly, in the case that the limiting member includes the first support arm 310 and the second support arm 320, the fitting plane 310a can be disposed on both the first support arm 310 and the second support arm 320.

Further, the winding and unwinding mechanism may further include a winding wheel 550, the winding wheel 550 is mounted on the driving member 510, and the transmission member 520 is in transmission connection with the winding wheel 550, so that the winding wheel 550 can rotate along with the driving member 510 to wind or unwind the transmission member 520. Furthermore, the winding wheel 550 is provided with a winding groove which can accommodate the transmission member 520, so as to prevent the transmission member 520 from being misaligned in the winding process to adversely affect the fitting relationship between the limiting member and the wheel 130. The specific size of the winding slot can be determined according to the size of the transmission member 520, such as the diameter, and is not limited herein.

Optionally, the transport cart disclosed in the embodiment of the present application may further include a detection part 900 that targets in place, the detection part 900 that targets in place may be an infrared sensor or a laser sensor, and the detection part 900 that targets in place is installed on the cart body 110, and under the condition that the limiting part is separated from the wheel 130, the detection part 900 that targets in place may be triggered, so that the driving part 510 no longer unreels the driving part 520, and it is ensured that the length of unreeling the driving part 520 meets the condition that the limiting part can be separated from the wheel 130, and the condition that the driving part 520 is excessively unreeled does not occur. Of course, when the limiting element is rotatably mounted on the vehicle body 110 and the limiting element can be driven by the driving element 510 to contact with the supporting surface, the in-place detection element 900 may also be used to detect whether the limiting element is separated from the supporting surface.

In addition, in the process that the driving element 510 winds the transmission element 520 and drives the limiting element to rotate, the limiting element gradually approaches the wheel 130, the torque at the output end of the driving element 510 gradually increases, and when the limiting element is attached to the wheel 130, the driving element 510 stops rotating and keeps the preset output torque to apply a constant driving torque to the limiting element, so that the limiting element and the wheel 130 are ensured to keep a better attachment relationship, and the contact relationship between the limiting element and the supporting surface is ensured to be relatively stable.
