Technical Field
[0001] This utility model relates to a rainproof cloth, specifically a rocker arm driven electric tricycle rainproof canopy. Background Technology
[0002] Most existing rainproof tarpaulins on the market are wrap-around, requiring a lot of frame support and prone to tipping over in windy and rainy weather. They are also inconvenient to store and cannot be switched at any time. In addition, existing rainproof tarpaulins require multiple ropes to fix them in place, making the operation cumbersome.
[0003] Currently, a utility model patent with publication number CN214648779U discloses a three-wheeled electric vehicle with an adjustable cargo box, relating to the field of three-wheeled electric vehicle technology. It includes a main body, a rainproof structure to prevent rainwater from getting in, an adjustment structure for adjusting the driving position, and a cargo guide structure for convenient unloading. A front wheel is installed on one side of the bottom of the main body, and rear wheels are installed at both the front and rear ends of the other side of the bottom of the main body. An adjustment structure is installed on one side of the main body, located at the top of the main body. A seat is installed at the top of the main body via the adjustment structure, and a cargo box is connected to the top of the main body away from the seat via a hinge key. The cargo guide structure is located at the bottom of the cargo box. This utility model provides a knob; rotating the knob rotates a threaded rod. When the threaded rod starts to rotate, it drives a threaded slider to move horizontally within the adjustment groove, changing the horizontal position of the seat and thus achieving adjustment of the driving position.
[0004] As can be seen from the above-disclosed technical content, as prior art, the utility model with announcement number CN214648779U uses an elastic cloth tube to cover the cargo box. However, pulling out the tarpaulin requires two people or one person to grab the lever and drag it outward, which is quite laborious. At the same time, the elastic cloth is only draped over the sides of the cargo box, and it is easily blown up in strong winds, affecting the rain-blocking effect. In addition, since the elastic cloth is not supported, when there is little cargo, rainwater will compress the elastic cloth, causing water to accumulate inside. If too much water accumulates, rainwater will flow into the cargo box, which limits the actual user experience. Utility Model Content
[0005] To address the problems existing in the prior art, this utility model provides a rocker arm driven electric tricycle rain canopy, which can be easily unfolded by a single person, effectively preventing strong winds from blowing the rain canopy away or lifting it, and preventing it from tipping over.
[0006] To achieve the above objectives, this utility model provides a rocker arm driven electric tricycle rain shelter, comprising a rain cloth winding drum. Both ends of the rain cloth winding drum are fixedly mounted on the back plate of the cargo bed via winding drum mounting rings. A rotating shaft is mounted on the central axis of the rain cloth winding drum via a bearing. A winding rocker arm is fixedly connected to the end of the rotating shaft. Rainproof cloth is wound around the surface of the rotating shaft. One end of the rainproof cloth extends from a rectangular through-hole near the bottom of the rain cloth winding drum. The extended rainproof cloth is fixedly connected to a rain cloth support rod. A pull rope connecting ring is fixedly installed at the center of the rain cloth support rod. Pull rope hooks are fixedly installed at both ends of the rain cloth winding drum. One end of the unfolded pull rope is fixedly connected to the pull rope connecting ring, and the other end of the unfolded pull rope is fixedly installed with a hook.
[0007] In addition, the rocker arm driven electric tricycle rain canopy proposed according to the above embodiments of this utility model may also have the following additional technical features:
[0008] As a further improvement to this utility model, lead weights and magnets are alternately installed on both sides of the rainproof cloth.
[0009] As a further improvement of this utility model, the distance between the lead weight and the magnet is not less than 30 centimeters, and the thickness is not more than 5 millimeters.
[0010] As a further improvement of this utility model, the winding drum mounting ring includes a connecting block, a connecting ring body, and a clamping protrusion. The connecting ring body is fixedly connected to the back plate of the cargo hopper through the connecting block. The connecting ring body is disconnected on the side opposite to the connecting block. The two ends of the disconnected connecting ring body are respectively equipped with clamping protrusions. The clamping protrusions are provided with screw holes and equipped with screws and nuts.
[0011] As a further improvement of this utility model, the rainproof cloth is equipped with a transverse reinforcing plate.
[0012] By means of the above solution, this utility model has at least the following advantages: Compared with conventional cargo boxes, by installing a rain cover roll-up ring on the cargo box, a single person can pull the pull rope to unfold the rain cover, so that the rain cover extends from the rain cover roll-up ring and covers the cargo box. When the rain cover is extended, the lead weights and magnets on both sides cause the rain cover to hang down naturally under the action of gravity, and the magnets make the sides of the rain cover adhere to the outer wall of the cargo box, effectively resisting strong winds. At the same time, the horizontal reinforcing plate provides support for the rain cover, which can effectively prevent strong winds from blowing the rain cover away or lifting it, and prevent it from tipping over.

[0017] The following description, in conjunction with the accompanying drawings, describes the rocker arm driven electric tricycle rain shelter of this utility model.
[0018] In Embodiment 1 of this application, as Figure 1 and Figure 2 As shown, this rocker-arm driven electric tricycle rain canopy (hereinafter referred to as "the present invention") includes a rain cloth winding drum 1, a winding rocker arm 2, a pull rope hook 3, an unfolding pull rope 4, a pull rope connecting ring 5, a rainproof cloth 6, a rainproof cloth support rod 7, and a winding drum mounting ring 8. Both ends of the rain cloth winding drum 1 are fixedly mounted on the back plate of the cargo compartment via the winding drum mounting ring 8. A rotating shaft is mounted on the central axis of the rain cloth winding drum 1 via a bearing. The end of the rotating shaft is fixedly connected to the winding rocker arm 2. The surface of the rotating shaft is wrapped with rainproof cloth 6. One section of the rainproof cloth 6 extends from a rectangular through-hole near the bottom of the rain cloth winding drum 1. The extended rainproof cloth 6 is fixedly connected to the rainproof cloth support rod 7. The pull rope connecting ring 5 is fixedly installed at the center of the rainproof cloth support rod 7. Pull rope hooks 3 are fixedly installed at both ends of the rain cloth winding drum 1. One end of the unfolding pull rope 4 is fixedly connected to the pull rope connecting ring 5, and the other end of the unfolding pull rope 4 is fixedly installed with a hook. The rainproof cloth 6 is equipped with a transverse reinforcing plate 63. A lead weight 61 and a magnet 62 are alternately installed on both sides of the rainproof cloth 6.
[0019] A three-wheeled electric vehicle with an adjustable cargo box (hereinafter referred to as "the patent") with utility model announcement number CN214648779U uses an elastic cloth tube to cover the cargo box. However, pulling out the tarpaulin requires two people or one person to pull it outward by holding the lever, which is quite strenuous. Furthermore, the elastic cloth only drapes over the sides of the cargo box, making it easily blown up in strong winds, affecting its rain-blocking effect. Additionally, because the elastic cloth lacks support, rainwater can compress it when there is little cargo, causing water to accumulate inside. Excessive water accumulation can lead to rainwater flowing into the cargo box. While the actual user experience has certain limitations, this invention uses a retractable ring 8 to install a rain cover retractable tube 1 on the cargo box. In rainy weather, a single person can pull the unfolding rope 4 to extend the rain cover 6 from the rain cover retractable tube 1 and cover the cargo box. When the rain cover 6 is pulled out, the lead weights 61 and magnets 62 on both sides cause the rain cover 6 to hang down naturally under the action of gravity, and the magnets 62 make the sides of the rain cover 6 adhere to the outer wall of the cargo box, effectively resisting strong winds. At the same time, the horizontal reinforcing plate 63 provides support for the rain cover 6, which can effectively prevent strong winds from blowing or lifting the rain cover and prevent it from tipping over.
[0020] This second embodiment is basically the same in structure as the first embodiment, the difference being that, as Figure 3 As shown, the winding drum mounting ring 8 includes a connecting block 81, a connecting ring body 82, and a clamping protrusion 83. The connecting ring body 82 is fixedly connected to the back plate of the cargo hopper through the connecting block 81. The connecting ring body 82 is disconnected on the side opposite to the connecting block 81. The clamping protrusion 83 is installed on both ends of the disconnected connecting ring body 82. The clamping protrusion 83 is provided with screw holes and equipped with screws and nuts.
[0021] To further optimize the working efficiency of this application and prevent the end of the rainproof cloth 6 from becoming too large after being rolled up, the distance between the lead weight 61 and the magnet 62 shall not be less than 30 centimeters, and the thickness shall not exceed 5 millimeters.
[0022] To use the equipment, simply install the rain cover on the cargo box of the rocker-arm driven electric tricycle.
[0023] When this utility model is used, its specific operation is as follows:
[0024] In use, the operator removes the hook of the unfolding rope 4 from the hook 3, then walks around to the rear of the cargo box. Since the unfolding rope 4 is elastic, it can be stretched. When the unfolding rope 4 is pulled, it drives the tarpaulin support rod 7, which in turn drives the rainproof tarpaulin 6 to extend from the tarpaulin roll-up drum 1. When the rainproof tarpaulin 6 extends, the lead weights 61 and magnets 62 on both sides of the rainproof tarpaulin allow the sides of the rainproof tarpaulin 6 to hang down naturally under the action of gravity. The magnets 62 also make the sides of the rainproof tarpaulin 6 adhere to the outer wall of the cargo box, effectively resisting strong winds. At the same time, the transverse reinforcing plate 63 provides support for the rainproof tarpaulin 6. After the rainproof tarpaulin 6 is extended into place, the hook at the end of the unfolding rope 4 is hooked onto the frame or other stress point at the rear of the cargo box to complete the unfolding. The width of the rainproof tarpaulin 6 is slightly larger than the width of the cargo box to ensure that the sides of the rainproof tarpaulin 6 can hang down outside the cargo box.
[0025] When retracting, simply remove the unfolding pull rope 4, and use the retracting rocker arm 2 to drive the retracting shaft of the rainproof cloth 6 inside the rainproof cloth retracting cylinder 1 to rotate, so that the rainproof cloth 6 is rewound onto the retracting shaft until the rainproof cloth support rod 7 is stuck outside the rectangular through hole at the bottom of the rainproof cloth retracting cylinder 1. Finally, re-hook the hook at the end of the unfolding pull rope 4 onto the pull rope hook 3 to complete the retracting.
[0026] The transverse reinforcing plate 63 installed on the rainproof cloth 6 can provide some support for the rainproof cloth 6 and prevent excessive rainwater from accumulating on the rainproof cloth 6.
[0027] In summary, the rocker arm driven electric tricycle rain canopy of this utility model uses a retractable ring 8 to install a rain cover retractable cylinder 1 on the cargo box. When it rains, a single person can pull the pull rope 4 to extend the rain cover 6 from the rain cover retractable cylinder 1 and cover the cargo box. When the rain cover 6 is pulled out, the lead weights 61 and magnets 62 on both sides cause the rain cover 6 to hang down naturally under the action of gravity, and the magnets 62 make the sides of the rain cover 6 adhere to the outer wall of the cargo box, effectively resisting strong winds. At the same time, the horizontal reinforcing plate 63 provides support for the rain cover 6, which can effectively prevent strong winds from blowing the rain cover away or lifting it, and prevent it from tipping over.
