[0002] In modern society, with the rapid development of urban construction, the disposal of construction waste has become an issue that cannot be ignored. In the underground parking garages of many residential communities and commercial buildings, construction waste needs to be cleaned and transported promptly. The traditional method relies on manually pushing garbage carts to transport the waste from the underground garage to designated waste disposal points.

[0003] However, existing garbage collection vehicles often do not have an anti-backward function, which may cause the vehicle to roll backward uncontrollably on slopes or uneven roads, resulting in safety accidents. Therefore, we propose a garbage collection vehicle with an anti-backward function. Utility Model Content

[0004] The purpose of this utility model is to provide a garbage transport trolley with an anti-backward function.

[0029] Example 1

[0030] Please see Figures 1-7 As shown, this utility model provides a technical solution: a garbage loading trolley with an anti-reverse function, comprising:

[0031] Support frame 1, fixing block 4, and fixing box 5;

[0032] Among them, the bottom of the load-bearing frame 1 is fixed with a left bottom plate 104 and a right bottom plate 103 on both sides. The bottom ends of the left bottom plate 104 are equipped with universal wheels 105, and the bottom ends of the right bottom plate 103 are equipped with wheel hub motors 108.

[0033] Among them, the fixing block 4 is fixed to the middle of the bottom of the right base plate 103. The lower end of the fixing block 4 is movably connected to the rotating shaft 401 through the bearing. The two ends of the outer surface of the rotating shaft 401 are fixed with L-shaped connectors 406 and winding wheels 402. The outer side of the winding wheels 402 is wrapped with a connecting belt 404. A V-shaped pad 405 is fixed on one side of the L-shaped connector 406.

[0034] The fixing box 5 is installed on one side of the fixing block 4. Guide rods 504 are fixed at both ends of one side of the inner cavity of the fixing box 5. A movable plate 503 slides on the outer surface of the guide rod 504, and the connecting strip 404 is fixedly connected to the movable plate 503. An iron metal plate 502 is installed on one side of the movable plate 503, and an electromagnet 501 corresponding to the iron metal plate 502 is installed on the other side of the inner cavity of the fixing box 5.

[0035] A groove adapted to the surface of the hub motor 108 is provided on one side of the V-shaped pad 405. U-shaped connecting seats 2 are fixed at both ends of the left side of the support frame 1. A damping rubber sleeve 201 is glued to the hinge rod inside the U-shaped connecting seat 2. A tow handle 202 is movably connected to the outside of the damping rubber sleeve 201. A control button 203 is installed at one end of the tow handle 202. An electrical box 3 is installed at the right end of the bottom of the support frame 1. A control box 301 and a lithium battery 302 are respectively installed at both ends inside the electrical box 3. The output end of the control button 203 is electrically connected to the input end of the control box 301. The output end of the control box 301 is electrically connected to the input end of the hub motor 108 and the electromagnet 501.

[0036] This technical solution: The operator starts the trolley by pulling the control key 203 on the handle 202. The signal is transmitted to the control box 301, and the control box 301 then powers the electromagnet 501 to generate a magnetic force, which attracts the iron metal plate 502. The iron metal plate 502 drives the movable plate 503 to slide along the guide rod 504, pulling the connecting belt 404. The connecting belt 404 drives the winding wheel 402 and the rotating shaft 401 to rotate, causing the V-shaped pad 405, which is fixed to the L-shaped connector 406, to flip up and retract, away from the tire surface of the hub motor 108.

[0037] Simultaneously, the control box 301 controls the hub motor 108 to work, providing auxiliary power to the trolley, allowing the operator to easily push the trolley forward. If the trolley is climbing a slope and a sudden power outage occurs (such as a lithium battery 302 malfunction or a broken circuit) or the operator loses control, the electromagnet 501 loses power, the magnetic force disappears, the movable plate 503 is no longer attracted, the connecting belt 404 loses tension, and the V-shaped pad 405, under its own weight, causes the rotating shaft 401 to rotate in the opposite direction, quickly resetting the V-shaped pad 405 downwards. If the trolley begins to reverse at this time, the tire of the hub motor 108 will roll backwards with the trolley, and its surface will immediately contact the reset V-shaped pad 405, causing the groove on one side of the V-shaped pad 405 to tighten. It tightly "locks" the tire surface, and at the same time, its bottom tip will rub against the ground. This small block instantly becomes a "brake block" wedged between the tire and the ground, effectively preventing the car from continuing to move backward and achieving parking lock. If the car needs to be fixed on flat ground, the foot brake of the universal wheel 105 can be used, or the anti-backward mechanism needs to be manually released after going uphill. The operator can actively cut off the power of the electromagnet 501 through the control key 203 (to make the V-shaped pad 405 fall and lock) or turn on the power (to make the V-shaped pad 405 retract and release). The front universal wheel 105 ensures flexible steering, and the rear hub motor 108 provides drive and braking. It is very convenient to move and operate. After reaching the destination, dump the garbage.

[0038] The vehicle is powered by a lithium battery 302, which has a long battery life and is easy to charge. The control button 203 on the towing handle 202 integrates the control at hand, realizing the convenience of human-computer interaction. The damping rubber sleeve 201 helps to fix the use angle of the towing handle 202.

[0039] Example 2

[0040] Based on Embodiment 1, this utility model is as follows: Figures 1-7 As shown, the two sides of the supporting frame 1 are movably connected by hinges to folding guardrails 101. Both ends of one side of the folding guardrail 101 are fixed with U-shaped positioning parts 106. Both ends of the inner side of the two folding guardrails 101 are provided with plug-in guardrails 102. Both sides of the plug-in guardrails 102 are fixed with U-shaped positioning sleeves 107 that are adapted to the U-shaped positioning parts 106.

[0041] This technical solution: By setting up the folding guardrail 101 and the plug-in guardrail 102, the folding guardrail 101 flips upward through the hinge, which drives the plug-in guardrail 102 and the U-shaped positioning sleeve 107. After the U-shaped positioning sleeve 107 is put on the U-shaped positioning piece 106 from top to bottom, it can position the two plug-in guardrails 102. This allows the trolley to be folded when it is empty or stored, saving space. When it is necessary to increase the capacity or transport loose garbage, it can be quickly unfolded and plugged in for fixation, flexibly adapting to different working conditions.

[0042] Example 3

[0043] Based on Embodiment 1, this utility model is as follows: Figures 1-7 As shown, a torsion spring 403 is fixed between the winding wheel 402 and the fixing block 4, and the torsion spring 403 is sleeved on the outside of the rotating shaft 401.

[0044] This technical solution: By setting the torsion spring 403, it can provide a rebound force when the V-shaped pad 405 is reset, and combined with the weight of the V-shaped pad 405 itself, it can ensure that the V-shaped pad 405 is reset quickly when the rotating shaft 401 rotates in the opposite direction.

[0045] It should be noted that when the V-shaped pad 405 is flipped upward, its torsion spring 403 is in a contracted and stored state, and the attraction force of the electromagnet 501 to the ferrous metal plate 502 is greater than the deformation and contraction force of the torsion spring 403.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
