Description

Technical Field

[0001] This utility model relates to accessories and devices for trams, specifically to a towable tram canopy. Background Technology

[0002] Currently, China has a huge number of electric vehicles, and their supporting products have also been widely promoted and developed. For example, the market share of products such as tarpaulins, raincoats, and helmets that are used with electric vehicles has also increased significantly. However, the supporting products commonly found on the market are of varying quality, have simple product structures, and low technological content. These shortcomings result in poor performance for consumers.

[0003] Taking tarpaulins as an example, tram tarpaulins are generally used to cover the vehicle. In rainy weather or when the vehicle is parked, the tarpaulin provides protection. Currently, the overall structure of tarpaulins is relatively simple, usually a simple sheet structure. When in use, it is unfolded to cover the vehicle's surface; when not in use, it needs to be folded up for storage. More complex designs incorporate tarpaulins in bags, providing better coverage. However, in actual use, both unfolding and storing tarpaulins present some inconveniences. Summary of the Invention

[0026] like Figures 1-5 The tractor-mounted tram canopy shown includes a housing 1, a traction unit 2, and a canopy 3.

[0027] Shell 1, cylindrical structure, for storing tarpaulin 3;

[0028] The traction unit 2 is movably mounted on the housing 1 and pulls one end of the tarpaulin 3.

[0029] The tarpaulin 3 is connected at one end to the traction unit 2 and at the other end to the inside of the housing 1, and is wound up by a roller 101 located inside the housing 1.

[0030] The housing 1 is formed by two semi-circular housings joined together, and the side of the housing 1 is provided with a mounting part 102 for mounting thereon; the traction part 2 is movably mounted on the top of the housing 1.

[0031] The scroll 101 is located at the center inside the housing 1, and a drive motor 103 for driving it is provided on one side of the scroll 101.

[0032] The housing 1 has a raised positioning seat 104 on its top; the traction part 2 includes a base 201 and a handheld part 202, the handheld part 202 is installed above the base 201, the bottom of the base 201 has a groove 203 corresponding to the positioning seat 104, the base 201 also has a fixing rod 204 for fixing the end of the tarpaulin 3, the end of the tarpaulin 3 is fixed to the fixing rod 204 in a wrapping manner; the housing 1 has buckles 105 on both sides, the base 201 has slots 205 corresponding to the buckles 105 on both sides, when the traction part 2 is installed on the top of the housing 1, the groove 203 corresponds to the positioning seat 104 on the top of the housing 1, the buckles 105 are fastened into the slots 205 on the base 201 to fix the traction part 2 on the top of the housing 1; the positioning seat 104 has a through slot 106, the tarpaulin 3 passes through the slot 106.

[0033] Furthermore, the housing 1 contains a first battery 107 that drives the drive motor 103 and a corresponding first signal board 108. The traction unit 2 contains a second battery 206 and a second signal board 207. The first signal board 108 and the second signal board 207 transmit signals wirelessly. The traction unit 2 is equipped with a drive switch 208. Example

[0034] In practical use, the overall width of the shell is relatively small, while the overall width required for the tarpaulin is relatively wide. Therefore, the tarpaulin will be partially folded when it is stored inside the shell. Repeated extraction and storage can easily cause the tarpaulin to be damaged. At the same time, it may cause jamming at the slot. Therefore, the slot is designed. The specific structure is shown in this embodiment.

[0035] The slot 206 is a continuous wave shape. The two semi-circular shells are respectively provided with corresponding toothed protrusions and toothed grooves at the positions corresponding to the slot 206. When the semi-circular shells are spliced ​​together, the toothed protrusions and toothed grooves intersect to form the wave-shaped slot. The spool 101 inside the shell 1 is provided with uniformly distributed cams 109. The cams 109 are uniformly distributed on the spool 101, and the gap between the spool 101 and the adjacent spool 101 corresponds to the slot 106.

[0036] In this embodiment, the slots are designed to form a wave shape, increasing the overall length and allowing wider tarpaulins to be stored inside the slots. This avoids repeated folding of the tarpaulin, which affects its service life, and also facilitates the pulling out and storing of the tarpaulin, making the overall process smoother.

[0037] This device is installed at the front or rear of the electric vehicle via the mounting section. The entire device is installed using bolts and other connecting parts, and the traction unit is fastened to the top of the housing.

[0038] When the tarpaulin needs to be opened, open the buckles on both sides, remove the towing unit, and then pull the towing unit and the tarpaulin out of the housing together to cover the vehicle body. When storing after use, hold the handle on the towing unit and press the drive switch on the towing unit. The signal plate will drive the motor inside the housing, causing it to rotate the roller and retract the tarpaulin into the housing. After storage, insert the towing unit into the top of the housing and secure it to the top of the housing with the buckles.
