DETAILED DESCRIPTION OF THE INVENTION

[0018] The present invention will be described in more detail below with reference to the drawings and examples. It is understood that the specific embodiments described in this specification are used only to explain the present invention, and do not limit the present invention. In addition, for ease of explanation, the drawings only show parts relevant to the present invention, and do not show the entire configuration.

Furthermore, the terms "first" and "second" are used only to distinguish between the two in the description and have no special meaning.

[0022] As shown in Figures 1 to 3, the present invention discloses an automatic rain cover reversing mechanism and an unmanned vehicle 900. The unmanned vehicle 900 includes a front section 910 and a loading body 920. The front section 910 is connected to the loading body 920, and the end of the loading body 920 away from the front section 910 is the rear section. The unmanned vehicle 900 also includes an automatic rain cover reversing mechanism, the purpose of which is to enable the unmanned vehicle 900 to successfully complete delivery even in bad weather such as rain or snow during its delivery process. Adding an automated rain cover device to accommodate the characteristics of unmanned driving operation makes it easier to use and reduces the need for additional human management.

[0023] The automatic rain protection reversing mechanism includes a rain protection module 100 and a reversing module 200. Here, the rain protection module 100 includes a frame 110 and a waterproof sheet 120. The waterproof sheet 120 is covered by the frame 110 and covers the transport car of the unmanned vehicle 900 during use. The rain protection module 100 secures the reversing module 200 of the transport car of the unmanned vehicle 900 to prevent cargo from getting wet in the rain, providing the unmanned vehicle 900 with a rainwater protection function and preventing it from being affected by bad weather such as rain or snow during transportation. In addition, the rain protection module 100 protects other mechanical modules and motor modules of the unmanned vehicle 900 and prevents damp rust of the mechanism from affecting the structural activity, thereby extending the service life of the automatic rain protection reversing mechanism.

[0024] Specifically, one end of the frame 110 is rotatably connected to the top of the front section 910 of the unmanned vehicle 900 on the side closest to the loading vehicle body 920, and the rotation axis of the frame 110 is parallel to the width direction of the unmanned vehicle 900. In this embodiment, a hinge 111 is provided between the frame 110 and the front section 910 to connect them, and the rain protection module 100 is fixed to the unmanned vehicle 900 via the hinge 111, making it possible to control the reversal angle of the rain protection module 100. The initial position of the rain protection module 100 is set to a horizontal state, and in the loaded state, the rain protection module 100 can keep the load shielded.

[0025] To achieve automatic opening and closing of the rain protection module 100, a first pulley 112 is installed at one end of the frame 110 near the rear of the unmanned vehicle 900, and a first slide rail 113 is installed on the bottom of the frame 110, extending along the vehicle length of the unmanned vehicle 900. That is, the first pulley 112 is installed at one end of the first slide rail 113 in the vehicle length direction and near the rear. The reversing module 200 is movably installed on the loading vehicle body 920, and similarly, a second slide rail 201 is installed on the side of the reversing module 200, and a second pulley 202 is installed at the top of the side of the reversing module 200. That is, the second pulley 202 is installed at the extended top of the second slide rail 201. When the automatic rain protection reversing mechanism is in a loaded state, the reversing module 200 is disposed parallel to the loading vehicle body 920. At this time, the reversing module 200 is driven by the motor to start reversing, and after reversing to a predetermined angle, the reversing module 200 abuts against the frame 110 to lift the rain protection module 100, and at the same time, slides along the first sliding rail 113 via the second pulley 202. When the second pulley 202 starts sliding along the first sliding rail 113 toward the rear of the unmanned vehicle 900, the first pulley 112 is swiftly placed on the second sliding rail 201, and the reversing module 200 then slides along the second sliding rail 201 until it is perpendicular to the loading vehicle body 920, thereby switching the automatic rain protection reversing mechanism to the unloading state. The automatic opening and closing of the rain protection module 100 can be achieved by the movement and reversing motion of the reversing module 200 itself, without the need for additional sensors or control units, and is simple in structure, convenient in operation, does not affect the loading and unloading of the transport car, has high reliability and stability, and is relatively low in manufacturing cost.

[0026] Furthermore, a collision prevention stopper 210 is provided on the bottom side of the reversing module 200, and a third pulley 211 is provided on the collision prevention stopper 210. As the first pulley 112 slides on the second slide rail 201 toward the third pulley 211, the third pulley 211 on the collision prevention stopper 210 abuts against the frame 110, and the first pulley 112 disengages from the second pulley 201. At this time, the third pulley 211 is slidably mounted on the first slide rail 113 and continues to slide toward the rear, allowing the reversing module 200 to be smoothly verticalized by the loading vehicle body 920, and the automatic rain cover reversing mechanism completes the switch from the loaded state to the unloaded state. This prevents interference between the bottom side corner of the reversing module 200 and the frame 110 as the first pulley 112 continues to slide, which would affect the reversing operation of the reversing module 200. The process of switching the automatic rain protection reversing mechanism from the unloaded state to the loaded state is the reverse of the above process, in which the third pulley 211 slides along the first slide rail 113 toward the front part 910 until the first pulley 112 contacts the second slide rail 201, and then the first pulley 112 slides toward the second pulley 202, at which point the third pulley 211 disengages from the first slide rail 113. As the first pulley 112 begins to slide along the second slide rail 201, the second pulley 202 gains momentum and abuts against the first slide rail 113, sliding toward the front part 910, the rain protection module 100 gradually returns to a horizontal state, and the reversing module 200 rotates to a position parallel to the loading vehicle body 920, and the automatic rain protection reversing mechanism switches to the loaded state.

[0027] For example, a rotating portion is provided on the bottom surface of the inversion module 200, and the inversion module 200 is selectively rotatably connected to one end near the rear portion of the loading vehicle body 920 via the rotating portion, and the rotation axis of the inversion module 200 is parallel to the vehicle width direction of the unmanned vehicle 900.

[0028] Specifically, the reversing module 200 is slidably installed on the loading vehicle body 920 along the vehicle length direction of the unmanned vehicle 900, a third slide rail is installed on the loading vehicle body 920, a fourth pulley 220 is installed on the bottom surface of the reversing module 200, and the fourth pulley 220 is slidably installed on the third slide rail. A stopper unit is provided at one end near the rear of the loading vehicle body 920, and when the reversing module 200 slides and its rotating unit abuts the stopper unit, the reversing module 200 reaches a reversible position where it can rotate relative to the loading vehicle body 920. When the automatic rain protection reversing mechanism switches from the loaded state to the unloaded state, the reversing module 200 first moves a predetermined distance toward the rear, and when the rotating unit abuts the stopper unit, the reversing module 200 starts reversing and abuts against the rain protection module 100. When the automatic rain cover reversing mechanism switches from an unloaded state to a loaded state, the reversing module 200 rotates to a position parallel to the loaded vehicle body 920, then continues to move toward the front part 910, and stops by moving the rotating part away from the reversible position.

[0029] Furthermore, the anti-collision stopper 210 can also limit the sliding of the reversing module 200. The reversing module 200 can slide until the anti-collision stopper 210 abuts against the side of the front part 910 that is closer to the loading vehicle body 920, and at this time the automatic rain cover reversing mechanism is in a stable loading state.

[0030] In this embodiment, an anti-vibration pad 114 is further provided on the bottom surface of the frame 110. The anti-vibration pad 114 is generally made of rubber, which can reduce noise and impact when the rain shield module 100 is backed off, and can play a buffering role, thereby further protecting the service life of the automatic rain shield reversal mechanism.

[0031] Optionally, the frame 110 may further be provided with a locking member. When the rain protection module 100 is parallel to and covered by the transport cage of the unmanned vehicle 900, the locking member can lock the relative positions of the frame 110 and the reversing module 200 to prevent the frame 110 from rotating, thereby preventing the unmanned vehicle 900 from reversing the rain protection module 100 due to swaying road conditions during transportation, which would affect the covering effect.

[0032] Obviously, the above-described embodiments of the present invention are merely examples for clearly illustrating the present invention, and do not limit the embodiments of the present invention. Those skilled in the art may make various obvious changes, adjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary to exhaust all embodiments here. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention should be included in the scope of protection of the claims of the present invention.
