Description

Technical Field

[0001] The present invention relates to the technical field of vehicles, and particularly relates to a unloading mechanism and a transport vehicle. Background Art

[0002] A carriage is a device provided at the rear of a goods transport vehicle for carrying items, and is widely used in the automotive field. The carriage generally includes a bottom plate, a left side plate, a right side plate, and a front plate, wherein the front plate serves to connect and fix the left side plate and the right side plate.

[0003] Currently, for some transport vehicles with a small loading capacity, such as pickup trucks, the carriage generally does not have a supporting loading and unloading device. As a result, when picking up or placing larger or heavier goods, multiple staff members need to cooperate. Some staff members stand inside the carriage to pick up the goods, and some staff members stand outside the carriage to receive the goods. This method is not only time-consuming and laborious, with low unloading efficiency, but also the goods are easily damaged due to the mistakes of the staff and fall. Summary of the Invention

[0004] Based on this, the purpose of the present invention is to provide a unloading mechanism and a transport vehicle, aiming to solve the technical problems of low unloading efficiency and insecurity in the prior art of transport vehicles.

[0005] One aspect of the present invention provides a unloading mechanism, which includes: two guiding brackets and a loading assembly. The two guiding brackets are arranged oppositely, and a plurality of transmission assemblies for conveying goods are provided between the two guiding brackets. Each transmission assembly forms a transmission channel extending along the length direction of the guiding bracket. The loading assembly is arranged at one end of the transmission channel. The loading assembly includes a support frame arranged on the guiding bracket and a support body rotatably arranged on the support frame. A buffering structure is provided between the support frame and the support body, and the buffering structure is used to apply a rotational resistance to the support body rotating due to carrying goods.

[0006] For the above-mentioned unloading mechanism, by setting the guiding brackets, when in use, the guiding brackets are placed obliquely between the carriage and the ground. When unloading goods, only need to place the goods on the transmission assembly on the guiding brackets, and the goods can slide along the transmission channel formed by the transmission assembly to the ground under the action of gravity. This method is both labor-saving and safe compared with manual loading and unloading. In addition, since there is an angle between the end of the guiding bracket fixed to the carriage and the bottom of the carriage, it is difficult for the staff members standing inside the carriage to operate to make the goods tilt and stably place on the transmission assembly on the guiding brackets. Therefore, in the embodiment of the present invention, a loading assembly with a buffering structure is also hinged at the end of the guiding bracket fixed to the carriage. The loading assembly is placed flat on the bottom of the carriage. When in use, first place the goods flat on the support body. Due to the action of the buffering structure, the staff members only need to apply a small force to the goods to make the goods tilt slowly and finally make the bottom of the goods stably fit on the transmission assembly, which facilitates the operation of the staff members and improves the loading and unloading efficiency.

[0007] According to the unloading mechanism described above of the present invention, the following additional technical features may also be provided:

[0008] Furthermore, the support frame includes two oppositely arranged support rods and a connecting rod. The support rods are rotatably connected to the guiding bracket, and the connecting rod is fixedly connected between the two support rods; the support body includes a rotating cylinder and a support plate. The rotating cylinder is sleeved on the connecting rod and can rotate relative to the connecting rod, and the support plate is fixedly connected to the rotating cylinder. The buffering structure is a torsion spring arranged between the connecting rod and the rotating cylinder.

[0009] Furthermore, an adaptive limiting structure is provided between the guiding bracket and the transmission assembly. Under the action of gravity, the adaptive limiting structure is used to release the rotational limit of the transmission assembly that rotates due to the loaded goods.

[0010] Furthermore, oppositely arranged shaft holes are formed on the two guiding brackets. The transmission assembly includes a rotating shaft and a roller. Both ends of the rotating shaft are rotatably arranged in the shaft holes, and the roller is sleeved on the rotating shaft and can rotate together with the rotating shaft. The adaptive limiting structure includes an anti-rotation limiting member and a driving component. The anti-rotation limiting member is in limiting cooperation with an anti-rotation limiting portion provided on the rotating shaft, and the driving component applies a limiting force that makes the anti-rotation limiting member and the anti-rotation limiting portion fit tightly, and drives the anti-rotation limiting member to separate from the anti-rotation limiting portion when the gravity acting on the anti-rotation limiting member is greater than the limiting force.

[0011] Furthermore, a first sliding groove is provided on the guiding bracket. The first sliding groove communicates with the shaft hole and has a width smaller than the diameter of the shaft hole. The anti-rotation limiting portion is a limiting groove circumferentially spaced along the end of the rotating shaft, and the anti-rotation limiting member is a gravity slider slidably arranged along the length direction of the first sliding groove. A convex block cooperating with the limiting groove is provided on the gravity slider, and the driving component is an elastic member arranged between the gravity slider and the inner wall of the first sliding groove. The elastic member can apply a supporting force that makes the limiting groove and the convex block engage.

[0012] Furthermore, the unloading mechanism further includes a speed reduction mechanism arranged between the guiding bracket and the transmission assembly. The speed reduction mechanism includes an air cavity and a reciprocating transmission member. The transmission assembly drives the reciprocating transmission member to compress and expand the cavity space of the air cavity, thereby being hindered from rotating.

[0013] Furthermore, the air cavity is arranged on the guiding bracket. One end of the air cavity is open and the open side is partially communicated with the end of the transmission assembly. The reciprocating transmission member includes a pull rod and a sealing block. One end of the pull rod is rotatably connected to a convex shaft at the rotating end of the transmission assembly, and the other end is hinged to the sealing block. Air holes are provided on the sealing block. The pull rod can push the sealing block to reciprocate along the inner wall of the air cavity as the transmission assembly rotates.

[0014] Furthermore, the unloading mechanism further includes an unloading component disposed at the other end of the transmission channel. The unloading component includes a tipping table, a blocking member, and an auxiliary tipping mechanism. The tipping table is fixedly connected to the transmission component, and the bearing plane of the tipping table is flush with the transmission channel. The blocking member is disposed on the guiding bracket and is used to limit the tipping table so that the tipping table rotates no more than the position where the bearing plane is perpendicular to the transmission channel. The auxiliary tipping mechanism is disposed between the guiding bracket and the tipping table, and under the action of gravity, the auxiliary tipping mechanism is used to apply a rotational force for the tipping table to tip due to the loaded goods.

[0015] Furthermore, the auxiliary tipping mechanism includes a gear rod, a push plate, a gear guide rail, and a pulling component. The gear parts at both ends of the gear rod are installed in the second sliding groove of the guiding bracket. A guiding support frame is installed in the second sliding groove, and the rod part of the gear rod is rollingly disposed on the guiding support frame. The push plate is disposed at the bottom of the tipping table and is fixedly connected to the rod part of the gear rod. The gear guide rail is disposed in the second sliding groove, and the gear part of the gear rod meshes with the gear guide rail. The pulling component includes a pull ring and a tension spring. The pull ring is rotatably connected to the gear rod, and the two ends of the tension spring are respectively fixedly connected to the inner wall of the second sliding groove and the pull ring.

[0016] Another aspect of the present invention lies in providing a transport vehicle, which includes a carriage. An installation groove is provided on the bottom plate of the carriage, and the aforementioned unloading mechanism is slidably installed in the installation groove. A limit support part is provided in the installation groove, and the limit support part is used to limit and support the support frame when the unloading mechanism is moved out of the installation groove.

The terms used in the description of this invention herein are for the purpose of describing specific embodiments only and are not intended to limit the invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0033] For ease of understanding of this invention, several embodiments of this invention are given below. However, this invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of this invention more thorough and comprehensive.

[0034] Reference Figures 2 to 10 , a unloading mechanism for an embodiment of this invention, the unloading mechanism includes two guiding brackets 100 and a loading assembly 300. The two guiding brackets 100 are arranged oppositely, and several transmission assemblies 200 for conveying goods are arranged between the two guiding brackets 100, and each transmission assembly 200 forms a transmission channel extending along the length direction of the guiding bracket 100.

[0035] The loading assembly 300 is arranged at one end of the transmission channel. The loading assembly 300 includes a support frame 310 arranged on the guiding bracket 100 and a support body 320 rotatably arranged on the support frame 310. A buffering structure is arranged between the support frame 310 and the support body 320, and the buffering structure is used to apply a rotational resistance to the support body 320 that rotates due to carrying goods.

[0036] During unloading, the support frame 310 is fixed on the carriage and supported on the bottom of the carriage. Since the two guiding brackets 100 can rotate relative to the support frame 310, the two guiding brackets 100 can be brought into contact with the ground and present a slope at an appropriate angle. The goods are placed on the support body 320. Due to the existence of the buffering structure, the operator only needs to apply a small force to slowly tilt the goods and finally make the bottom of the goods fit on the transmission assembly 200, and finally the goods slide down along the transmission channel to the ground.

[0037] Optionally, the support frame 310 includes two oppositely arranged support rods 311 and a connecting rod 312. The support rod 311 is rotatably connected to the guiding bracket 100, and the connecting rod 312 is fixedly connected between the two support rods 311.

[0038] The support body 320 includes a rotating cylinder 321 and a support plate 322. The rotating cylinder 321 is sleeved on the connecting rod 312 and can rotate relative to the connecting rod 312. The support plate 322 is fixedly connected to the rotating cylinder 321, and the buffering structure is a torsion spring arranged between the connecting rod 312 and the rotating cylinder 321.

[0039] During unloading, the goods are placed on the support plate 322. The torsion spring between the support plate 322 and the rotating cylinder 321 will support the goods. Since the support plate 322 can rotate relative to the connecting rod 312, the operator can apply a small force to slowly tilt the goods, and finally make the bottom of the goods fit on the transmission component 200. Finally, the goods slide down along the transmission channel to the ground, which is convenient for the operator to unload heavier goods.

[0040] In some embodiments, as Figure 8 shown, an adaptive limiting structure 400 is provided between the guiding bracket 100 and the transmission component 200. Under the action of gravity, the adaptive limiting structure 400 can release the rotational limit of the transmission component 200 that rotates due to carrying goods. By setting the adaptive limiting structure 400, the rotation of the transmission component 200 can be restricted during the driving of the transport vehicle, thereby preventing the transmission component 200 from shaking due to inertia, resulting in structural damage and affecting the service life. In addition, when the unloading mechanism is set up for unloading, the adaptive limiting structure 400 can automatically release the rotational limit of the transmission component 200, thus facilitating unloading.

[0041] In some embodiments, as Figure 5 and Figure 8 shown, opposite shaft holes 110 are provided on the two guiding brackets 100. The transmission component 200 includes a rotating shaft 210 and a roller 220. The two end portions of the rotating shaft 210 are rotatably arranged in the shaft holes 110, and the roller 220 is sleeved on the rotating shaft 210 and can rotate together with the rotating shaft 210.

[0042] As Figure 8 shown, the adaptive limiting structure 400 includes an anti-rotation limiting member 410 and a driving member 420. The anti-rotation limiting member 410 is in limiting cooperation with an anti-rotation limiting portion provided on the rotating shaft 210. The driving member 420 applies a limiting force to make the anti-rotation limiting member 410 and the anti-rotation limiting portion fit tightly, and drives the anti-rotation limiting member 410 to separate from the anti-rotation limiting portion when the gravity acting on the anti-rotation limiting member 410 is greater than the limiting force.

[0043] In some embodiments, as Figure 8 shown, a first sliding groove 120 is provided on the guiding bracket 100. The first sliding groove 120 is communicated with the shaft hole 110 and has a width smaller than the diameter of the shaft hole 110, which can prevent the rotating shaft 210 from moving from the shaft hole 110 into the first sliding groove 120.

[0044] Optionally, the anti-rotation limiting portion is a limiting groove 211 circumferentially arranged at intervals along the end of the rotating shaft 210, and the anti-rotation limiting member 410 is a gravity slider slidably arranged along the length direction of the first sliding groove 120. A convex block 411 cooperating with the limiting groove 211 is provided at one end of the gravity slider close to the rotating shaft 210.

[0045] Optionally, the limiting groove 211 is a groove with a small opening and a large interior, and one end of the convex block 411 close to the limiting groove 211 protrudes upward.

[0046] The driving component 420 is an elastic member disposed between the gravity slider and the inner wall of the first sliding groove 120, and the elastic member can apply a supporting force that causes the limiting groove 211 and the convex block 411 to engage. It can be understood that the aforementioned elastic member can be a component such as a spring.

[0047] Reference Figure 1 and Figure 2 , respectively, show a transport vehicle and a carriage 700 installed on the transport vehicle according to an embodiment of the present invention. An installation groove 720 is provided on the bottom plate 710 of the carriage 700, and the aforementioned unloading mechanism is slidably installed in the installation groove 720. A limiting support portion is provided in the installation groove 720, and the limiting support portion is used to limit and support the support frame 310 when the unloading mechanism is moved out of the installation groove 720.

[0048] During unloading, the guiding bracket 100 is in an inclined state. At this time, the gravity acting on the gravity slider is greater than the limiting force provided by the elastic member, and the gravity slider moves downward, causing the front end of the convex block 411 to be withdrawn from the limiting groove 211, so that the gravity slider is separated from the rotating shaft 210, and thus the gravity slider does not limit the rotation of the rotating shaft 210.

[0049] At the same time, the gravity slider presses the elastic member to compress the elastic member. When the guiding bracket 100 is placed flat in the installation groove 720 in the carriage 700, the elastic member will rebound and then push the gravity slider close to the rotating shaft 210. When the transport vehicle brakes suddenly or starts, due to inertial movement, the lower side of the roller 220 contacts the bottom wall of the installation groove 720 and rotates to drive the rotating shaft 210 to rotate. When the limiting groove 211 rotates to face the convex block 411, the convex block 411 will be instantaneously stuck into the limiting groove 211 under the action of the supporting force of the elastic member, so that the rotating shaft 210 is limited and cannot rotate, thereby ensuring that the transmission assembly 200 does not shake during transportation and extending its service life.

[0050] In some embodiments, as Figure 9 shown, the unloading mechanism further includes a speed reducing mechanism 500 disposed between the guiding bracket 100 and the transmission assembly 200. The speed reducing mechanism 500 includes an air chamber 510 and a reciprocating transmission member 520. During unloading, when the transmission assembly 200 rotates, it drives the reciprocating transmission member 520 to perform a reciprocating motion in the air chamber 510, causing the reciprocating transmission member 520 to compress and expand the chamber space of the air chamber 510. And during the process of the reciprocating transmission member 520 compressing and expanding the chamber space of the air chamber 510, the transmission assembly 200 is subjected to a resistance force opposite to its movement direction and is transmitted to the transmission assembly 200, thereby achieving the effect of limiting the speed of the transmission assembly 200.

[0051] In some embodiments, asFigure 9 As shown, an air chamber 510 is provided on the guiding bracket 100. One end of the air chamber 510 is open, and the open side of the air chamber 510 is in partial communication with the end portion of the transmission assembly 200. The reciprocating transmission member 520 includes a pull rod 521 and a sealing block 522. The pull rod 521 is inserted from the open side of the air chamber 510. One end of the pull rod 521 is rotatably connected to the convex shaft 212 at the rotating end of the transmission assembly 200, and the other end of the pull rod 521 is hinged to the sealing block 522. An air hole 523 is provided on the sealing block 522, and the air hole 523 penetrates through the sealing block 522.

[0052] When unloading goods, the goods carried on the transmission assembly 200 slide downward, driving the roller 220 of the transmission assembly 200 to rotate. The roller 220 then drives the rotating shaft 210 to rotate. The rotation of the rotating shaft 210 drives the convex shaft 212 to perform a circular motion. The convex shaft 212 pulls one end of the pull rod 521, causing the other end of the pull rod 521 to drive the sealing block 522 to slide reciprocally along the inner wall of the air chamber 510. Since the interior of the air chamber 510 is sealed by the sealing block 522, the sealing block 522 compresses and expands the internal space of the air chamber 510 under the action of the pull rod 521. At this time, the gas can only slowly flow out and flow into the air chamber 510 through the air hole 523, thereby restricting the reciprocating movement speed of the sealing block 522, and further restricting the rotation speed of the rotating shaft 210, so that the roller 220 does not rotate too fast, achieving the effect of reducing the descending speed of the goods and facilitating the operator to adjust and receive the goods.

[0053] When transporting the unloading mechanism, since the unloading mechanism will move inertially and cause the transmission assembly 200 to rotate, restricting the rotation of the transmission assembly 200 through the adaptive limiting structure 400 can prevent the reciprocating transmission member 520 from repeatedly performing reciprocating motions in the air chamber 510 and extend the service life of the speed reduction mechanism 500. In some cases, even if the adaptive limiting structure 400 temporarily loses the limit on the rotation of the transmission assembly 200 due to inertial movement, the speed reduction mechanism 500 can reduce the rotation speed of the transmission assembly 200, thereby reducing the impact force of the convex block 411 on the limiting groove 211 when the gravity slider re-limits the rotating shaft 210 and extending the service life of the adaptive limiting structure 400.

[0054] In some embodiments, such as Figure 4 、 Figure 7 and Figure 10 As shown, the unloading mechanism further includes an unloading assembly 600 provided at the other end of the transmission channel. The unloading assembly 600 includes a turning table 610, a blocking member 620, and an auxiliary turning mechanism 630. The turning table 610 is fixedly connected to the transmission assembly 200, and the bearing plane of the turning table 610 is flush with the transmission channel.

[0055] Optionally, a buffer layer made of rubber is provided on the turning table 610, and the buffer layer can buffer the goods conveyed by the transmission assembly 200.

[0056] The blocking member 620 is fixed to the guiding bracket 100. The height of the blocking member 620 is greater than the height of the bearing plane of the flipping table 610. The blocking member 620 limits the flipping table 610 to rotate no more than the position where its bearing plane is perpendicular to the transmission channel. Moreover, the blocking member 620 is located at the rear side of the flipping table 610, and can block the goods conveyed by the transmission assembly 200 to prevent the goods from directly falling to the ground and being damaged.

[0057] The auxiliary flipping mechanism 630 is arranged between the guiding bracket 100 and the flipping table 610. Under the action of gravity, the auxiliary flipping mechanism 630 can apply a rotational force for the flipping table 610 to flip due to carrying goods.

[0058] In some embodiments, as Figure 10 shown, the auxiliary flipping mechanism 630 includes a gear rod 631, a push plate 632, a gear guide rail 634, and a pulling assembly. The gear portions at both ends of the gear rod 631 are installed in the second sliding groove 130 of the guiding bracket 100. A guiding support frame 131 is installed in the second sliding groove 130, and the rod portion of the gear rod 631 is rollingly arranged on the guiding support frame 131. The push plate 632 is arranged at the bottom of the flipping table 610 and fixedly connected to the rod portion of the gear rod 631. The mass of the push plate 632 is greater than the mass of the flipping table 610. The gear guide rail 634 is installed at the bottom in the second sliding groove 130, and the gear portion of the gear rod 631 meshes with the gear on the gear guide rail 634. The pulling assembly includes a pull ring 635 and a tension spring 636. The pull ring 635 is rotatably connected to the gear rod 631, and the two ends of the tension spring 636 are respectively fixedly connected to the inner wall of the second sliding groove 130 and the pull ring 635.

[0059] When unloading, the guiding bracket 100 is in an inclined state. The operator applies a thrust to the goods to make the flipping table 610 rotate backward. When the gravity received by the push plate 632 is greater than the pressure applied by the flipping table 610, the push plate 632 drives the gear rod 631 to move downward along the gear guide rail 634, thereby causing the gear portion of the gear rod 631 to rotate. At the same time, when the gear rod 631 moves downward, it will also drive the pull ring 635 to move downward, stretching the tension spring 636. The rotation of the gear portion of the gear rod 631 drives the push plate 632 to rotate. At this time, the push plate 632 will provide a flipping force for the flipping table 610, and the operator can reduce the thrust applied to the goods at this time. In addition, when the flipping table 610 rotates a certain angle, the resistance to the rotation of the flipping table 610 becomes smaller. Through the speed reducing mechanism 500, the flipping table 610 can be prevented from rotating too fast to the position where its bearing plane is perpendicular to the transmission channel, ensuring that the goods fall smoothly to the ground.

[0060] After the unloading is completed, first press the flipping table 610 inward to reset it, and then insert the unloading mechanism back into the installation groove 720 to reset the unloading mechanism. During the reset process of the flipping table 610, the flipping table 610 squeezes the push plate 632 inward, causing the push plate 632 to drive the gear rod 631 to move upward along the gear guide rail 634, and further causing the gear portion of the gear rod 631 to rotate. Since the tension spring 636 is in a stretched state at this time, the tension spring 636 can provide a pulling force along the direction of the gear guide rail 634, so that the operator only needs to press the flipping table 610 with a very small force to reset the flipping table 610.

[0061] In some embodiments, such as Figure 2 , Figure 3 and Figure 4 shown, one end of the unloading mechanism close to the loading assembly 300 is arranged at the front side inside the installation groove 720. The two side walls of the installation groove 720 are provided with third sliding grooves 721. A plug rod 313 is arranged on the outer side of the support frame 310. The plug rod 313 is rotatably connected with a rotating cylinder 314. The rotating cylinder 304 is slidably arranged in the third sliding groove 721. The limit support portion is a limit rod 730 fixed at the rear side inside the installation groove 720. A hook 315 cooperating with the limit rod 730 is arranged on the support frame 310. The height of the limit rod 730 is equal to the height of the hook 315, and is greater than the height of the guide bracket 100, the plane where the transmission channel is located, and the flipping table 610.

[0062] When using the unloading mechanism, pull the guide bracket 100 backward from below the limit rod 730. The guide bracket 100 drives the rotating cylinder 304 to slide in the third sliding groove 721. As the guide bracket 100 is gradually pulled out, the distance between the hook 315 arranged on the support frame 310 and the limit rod 730 gets closer and closer, and finally hooks the limit rod 730.

[0063] In some embodiments, such as Figure 4 shown, a roller 140 is rotatably connected to one end of the guide bracket 100 close to the unloading assembly 600. Through the roller 140, a slope with a proper angle is presented between the guide bracket 100 and the ground to facilitate unloading.

In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

Their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent for the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention.
