[0027] Example 1
[0028] Regarding the problem 1 mentioned above: When existing trucks need to be covered with rain curtains, the rain curtains need to be manually pulled to open or close, which is cumbersome and wastes manpower.
[0029] The solution is as follows: An electric rain curtain for bulk cargo trucks in this embodiment includes a cargo box 100, a rain curtain box 200, and a lifting platform 300.
[0030] Two fixing columns 110 are installed on the side wall of the carriage 100. The two fixing columns 110 are symmetrically installed at both ends of the side wall of the carriage 100. The height of the fixing columns 110 is the same as the height of the carriage 100, and the top of the fixing columns 110 is flush with the top of the carriage 100. The side wall of the fixing columns 110 is provided with a sliding groove 120. A first motor 130 is installed on the top of one of the fixing columns 110. The output end of the first motor 130 extends into the sliding groove 120 and is equipped with a threaded rod 140. The two sliding grooves 120 are respectively opened on the opposite side walls of the two fixing columns 110. Not shown in the figure, a shell can be added to the outside of the first motor 130 to prevent water from entering the first motor 130, or the first motor 130 and the threaded rod 140 can be installed inside the sliding groove 120 as needed.
[0031] The rain curtain box 200 is located on the top of the side wall of the carriage 100. The rain curtain box 200 has an internal cavity. The winding roller 210 is rotatably connected inside the rain curtain box 200. A torsion spring connects the winding roller 210 and the rain curtain box 200. A slot 220 is opened at the bottom of the rain curtain box 200. A rain curtain fabric 230 is wound around the outer wall of the winding roller 210. The bottom end of the rain curtain fabric 230 extends from the bottom of the slot 220. The lifting plate 300 is located between two fixed columns 110. The bottom end of the rain curtain fabric 230 is connected to... At the top of the lifting plate 300, two sliders 310 are installed at both ends. The two sliders 310 extend into two sliding grooves 120 respectively. One slider 310 has a threaded hole 320 at its top, through which a threaded rod 140 rotates. A first guide rod 150 is installed inside the other sliding groove 120, and a first guide hole 330 is opened at the top of the other slider 310, through which the first guide rod 150 passes. By starting the first motor 130, the threaded rod 140 rotates. When the threaded rod 140 rotates, it uses a screw mechanism to push the slider 310, causing the lifting plate 300 to move downwards. The lifting plate 300 pulls the rain curtain 230 downwards, causing the rain curtain 230 to rotate and compress the torsion spring, until the lifting plate 300 moves to the bottom of the carriage 100. At this point, the rain curtain 230 is fully unfolded, and the lifting plate 300 pulls the rain curtain 230 taut. After use, the first motor 130 is started. 30 drives the threaded rod 140 to reverse, and the threaded rod 140 uses the screw structure to push the slider 310 to drive the lifting plate 300 to move upward. At this time, the rain curtain 230 is relaxed, and the torsion spring rebounds to drive the take-up roller 210 to reverse. When the take-up roller 210 reverses, it rewraps the rain curtain 230 on the surface of the take-up roller 210 until the lifting plate 300 moves to the bottom of the rain curtain box 200 and resets. At this time, the rain curtain 230 is wrapped around the outer wall of the take-up roller 210, completing the take-up of the rain curtain 230.
[0032] Example 2
[0033] Regarding the second problem to be solved above: During the rolling up process after use, the rainwater on the outer surface of the existing rain curtains for bulk trucks is rolled up along with the rain curtains, and it is difficult to dry inside the rain curtain box, which will lead to damage to the rain curtains over time.
[0034] The solution is as follows: The electric rain curtain for bulk cargo trucks in this embodiment also includes a sliding plate 400.
[0035] Two first fixing plates 240 are symmetrically installed at the bottom of the rain curtain box 200. A sponge cleaning roller 250 is rotatably connected between the two first fixing plates 240. The outer wall of the sponge cleaning roller 250 is in contact with the outer wall of the rain curtain fabric 230. One end of the winding roller 210 extends out of the side wall of the rain curtain box 200 and is equipped with a first pulley 211. One end of the sponge cleaning roller 250 extends out of the side wall of the first fixing plate 240 and is equipped with a second pulley 251. The first pulley 211 and the second pulley 251 are connected by a belt. Two second fixing plates 240 are symmetrically installed on the side wall of the rain curtain box 200. A fixed plate 260 is provided, with a second motor 270 mounted on the side wall of one of the second fixed plates 260. The output end of the second motor 270 extends between the two second fixed plates 260 and is equipped with a reciprocating threaded rod 271. A sliding plate 400 is located on the side wall of the rain curtain box 200. An extrusion plate 410 is mounted on the side wall of the sliding plate 400, which extrudes the outer wall of the sponge cleaning roller 250. A reciprocating threaded hole 420 is provided on the side wall of the sliding plate 400, through which the reciprocating threaded rod 271 rotates. A second guide rod 280 is installed between the two second fixed plates 260. A second guide hole 430 is provided on the side wall of plate 400, and a second guide rod 280 passes through the second guide hole 430. Not shown in the figure, a protective shell can be provided on the exterior of the second motor 270 to prevent it from being directly exposed to rainwater. When the rain curtain 230 is rolled up, the rotation of the winding roller 210 drives the first pulley 211 to rotate. The first pulley 211 drives the second pulley 251 to rotate via a belt. The second pulley 251 drives the sponge cleaning roller 250 to rotate. When the sponge cleaning roller 250 rotates, it cleans the surfaces of the surfaces passing through it. The rain curtain fabric 230 is cleaned of rainwater. At the same time, the second motor 270 is started to drive the reciprocating screw rod 271 to rotate. When the reciprocating screw rod 271 rotates, the screw structure pushes the slide plate 400 to drive the extrusion plate 410 to move back and forth between the two second fixed plates 260. When the extrusion plate 410 moves, it squeezes the sponge cleaning roller 250 and squeezes out the water on the surface of the sponge cleaning roller 250. This can wipe away as much rainwater as possible from the surface of the rain curtain during the rain curtain rolling process, and can prevent rainwater from being trapped inside the rain curtain box 200 and causing damage to the rain curtain fabric 230.
[0036] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
