[0030] like Figures 1 to 3As shown in the , the utility model discloses an automatic canopy flipping mechanism and an unmanned vehicle 900. The unmanned vehicle 900 includes a front end 910 and a load-bearing body 920. The front end 910 is connected to the load-bearing body 920. The end of the load-bearing body 920 away from the front end 910 is the rear end. It also includes an automatic canopy flipping mechanism. The purpose of designing the automatic canopy flipping mechanism is that during the process of the unmanned vehicle 900 transporting express, the unmanned vehicle 900 can also complete the delivery of express normally in rainy and snowy weather. In order to cooperate with the characteristics of unmanned driving operation, a highly automated rainproof device is added for easy use and saving extra manpower management.

[0031] The automatic canopy flipping mechanism includes a canopy module 100 and a flipping module 200. The canopy module 100 comprises a frame 110 and a tarp 120. The tarp 120 covers the frame 110 and, during use, covers the transport box cage on the unmanned vehicle 900 and the flipping module 200, which is used to secure the transport box cage on the unmanned vehicle 900. This protects the cargo from getting wet, providing rain protection for the unmanned vehicle 900 and shielding it from adverse weather conditions such as rain and snow during transportation. It also protects other mechanical and motor modules on the unmanned vehicle 900, preventing moisture and rust from affecting its mobility and extending the service life of the automatic canopy flipping mechanism.

[0032] Specifically, one end of the frame 110 is pivotally connected to the top of the front end 910 of the unmanned vehicle 900, near the supporting body 920, with the rotation axis of the frame 110 parallel to the width of the unmanned vehicle 900. In this embodiment, a hinge 111 is provided between the frame 110 and the front end 910. The hinge 111 can be used to secure the canopy module 100 to the unmanned vehicle 900 and control the tilt angle of the canopy module 100. The initial position of the canopy module 100 is set to a horizontal state. When loaded, the canopy module 100 can maintain coverage of the cargo.

[0033] In order to realize the automatic opening and closing of the canopy module 100, a first pulley 112 is provided at one end of the frame 110 close to the rear of the unmanned vehicle 900, and a first slide 113 is provided on the bottom surface of the frame 110. The first slide 113 extends along the length of the unmanned vehicle 900, that is, the first pulley 112 is provided at the end of the first slide 113 along the length of the vehicle and close to the rear of the vehicle; the flip module 200 is movably placed on the load-bearing body 920. Similarly, a second slide 201 is provided on the side of the flip module 200, and a second pulley 202 is provided on the top of the side of the flip module 200, that is, the second pulley 202 is provided at the extended top of the second slide 201. When the automatic canopy flipping mechanism is in the loading state, the flipping module 200 is placed parallel to the load-bearing body 920. At this time, the flipping module 200 starts to flip through the motor drive. After flipping to a certain angle, the flipping module 200 can abut against the frame 110 and lift the canopy module 100, and at the same time slide on the first slide 113 through the second pulley 202; when the second pulley 202 slides out of the first slide 113 toward the rear of the unmanned vehicle 900, the first pulley 112 can be placed on the second slide 201 and start to slide until the flipping module 200 is perpendicular to the load-bearing body 920, and the automatic canopy flipping mechanism is converted to the unloading state. The automatic opening and closing of the canopy module 100 can be realized by relying on the movement and flipping movement of the flipping module 200 itself, without adding any sensors and controls. The structure is simple, the operation is convenient, and it does not affect the loading and unloading of the transport cage. It has high reliability and stability, and the manufacturing cost is relatively low.

[0034] Furthermore, an anti-collision limit portion 210 is protruded from the bottom side of the flip module 200, and a third pulley 211 is provided on the anti-collision limit portion 210. When the first pulley 112 slides on the second slide 201 toward the direction close to the third pulley 211, until the third pulley 211 on the anti-collision limit portion 210 abuts against the frame 110, the first pulley 112 disengages from the second slide 201. At this time, the third pulley 211 can be slid onto the first slide 113 and continue to slide toward the rear of the vehicle, which can more smoothly make the flip module 200 perpendicular to the load-bearing body 920, completing the entire operation process of the automatic canopy flipping mechanism from the loading state to the unloading state, and avoiding the interference between the side bottom angle of the flip module 200 and the frame 110 when the first pulley 112 continues to slide, affecting the flipping action of the flip module 200. It can be understood that the process of converting the automatic canopy flipping mechanism from the unloading state to the loading state is opposite to the above-mentioned process. The third pulley 211 first slides along the first slide 113 toward the front of the vehicle 910 until the first pulley 112 contacts the second slide 201, and the first pulley 112 slides in the direction close to the second pulley 202. At this time, the third pulley 211 is disengaged from the first slide 113; when the first pulley 112 slides out of the second slide 201, the second pulley 202 abuts against the first slide 113 and slides toward the front of the vehicle 910. The canopy module 100 gradually falls back to a horizontal state. At the same time, the flip module 200 rotates to be placed parallel to the load-bearing body 920, and the automatic canopy flipping mechanism is converted to a loading state.

[0035] For example, a rotating portion is provided on the bottom surface of the flip module 200 , and the flip module 200 can be selectively rotatably connected to the end of the supporting body 920 near the rear of the vehicle through the rotating portion, and the rotation axis of the flip module 200 is parallel to the width direction of the unmanned vehicle 900 .

[0036] Specifically, the flip module 200 is slidably mounted on the supporting body 920 along the length of the unmanned vehicle 900. The supporting body 920 is provided with a third slideway, and a fourth pulley 220 is provided on the bottom surface of the flip module 200, which can slide on the third slideway. A limit portion is provided at one end of the supporting body 920 near the rear of the vehicle. When the flip module 200 slides until the rotating portion abuts the limit portion, the flip module 200 reaches a reversible position and can rotate relative to the supporting body 920. When the automatic canopy flipping mechanism switches from a loading state to an unloading state, the flip module 200 first moves a distance toward the rear of the vehicle until the rotating portion abuts the limit portion, at which point the flip module 200 begins to flip and abuts the canopy module 100. When the automatic canopy flipping mechanism switches from an unloading state to a loading state, after the flip module 200 rotates to a position parallel to the supporting body 920, it continues to move toward the front of the vehicle 910, causing the rotating portion to disengage the reversible position and stop.

[0037] Furthermore, the anti-collision limit part 210 can also limit the sliding of the flip module 200. The flip module 200 can slide until the anti-collision limit part 210 abuts against the side of the front of the vehicle 910 close to the supporting body 920. At this time, the automatic canopy flipping mechanism is in a stable loading state.

[0038] In this embodiment, a shock-absorbing pad 114 is also provided on the bottom surface of the frame 110. The shock-absorbing pad 114 is generally made of rubber and can reduce noise and impact when the canopy module 100 falls back and closes, thereby playing a buffering role and further protecting the service life of the automatic canopy flip mechanism.

[0039] Optionally, the frame 110 is also provided with a locking part. When the canopy module 100 covers the transport box cage on the unmanned vehicle 900 in parallel, the locking part can lock the relative position of the frame 110 and the flip module 200 to prevent the frame 110 from rotating, thereby avoiding the canopy module 100 from tilting and flipping due to bumpy road conditions during transportation of the unmanned vehicle 900, thereby affecting the covering effect.

[0040] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
