Description

Technical Field

[0001] This utility model belongs to the technical field of vehicle protection devices, and in particular, it is a compact robotic arm-type vehicle cover retraction and extension device. Background Technology

[0002] When vehicles are parked outdoors for extended periods, owners often need to install protective netting on the vehicle's exterior to effectively protect it. For civilian vehicles, the netting provides protection against dust, rain, static electricity, UV rays, and freezing. For special or military vehicles, the netting can also serve as camouflage by painting appropriate colors and patterns on it. However, due to the large size of the netting, manually unfolding or retracting it is extremely labor-intensive. In recent years, automated and mechanized netting deployment and retraction devices have become increasingly widely used.

[0003] For example, patent document with authorization announcement number "CN1215943C" discloses an automatic car cover retraction device, including a car cover, a car cover box, a geared motor, a controller, and a car cover retraction mechanism. The key features are: the car cover retraction mechanism includes a left support frame and a right support frame erected on both sides of an upper and lower rotating shaft, respectively; upper support arms and lower support arms are respectively provided on the outer sides of the left and right support frames; the two ends of the upper and lower rotating shafts pass through the left and right support frames and are respectively mounted on the upper and lower support arms on the left and right sides; the upper support arms on the left and right sides are movable arms, capable of rotating at a certain angle along their corresponding upper fixed shafts at the rear; the front parts of the upper and lower support arms on the left and right sides are respectively tightened by a tension spring; multiple rubber rollers are respectively mounted on the upper and lower rotating shafts; upper and lower protective nets are respectively provided on the outside of the upper and lower rotating shafts; and the lower rotating shaft is driven by a geared motor. By adopting this patented technology and setting up automated mechanical assembly, the efficiency of unfolding and retracting car covers is improved, and the labor intensity of people is reduced.

[0004] However, existing protective cover retraction devices generally include rollers and drive motors. The drive motors are used to drive the rollers to rotate. When the rollers rotate, the protective cover extends along the outer circumference of the rollers and blocks the vehicle, or the protective cover is wrapped and rolled into a cylindrical shape along the outer circumference of the rollers and manually stored away. However, since the rollers themselves are also cylindrical, the length of the rollers determines the width of the protective cover's coverage area. In order to expand the protective cover's coverage area for the vehicle, the length of the rollers needs to be increased, making the protective cover retraction device increasingly bulky. Many protective cover retraction devices are usually installed on the roof of the vehicle and move with the vehicle. When the protective cover retraction device is too bulky, it prevents the vehicle from passing through the height restriction frames set on the road. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a compact robotic arm-type vehicle cover retraction and extension device.

[0006] This utility model is achieved through the following technical solution.

Detailed Implementation

[0020] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0021] like Figures 1 to 6 As shown, this utility model provides a compact robotic arm-type vehicle guard retraction and extension device, including a saddle box 1, a female swing arm 2, and a male swing arm 3. The saddle box 1 is disposed on the top surface of the vehicle. The surface of the female swing arm 2 is provided with a receiving groove. One end of the female swing arm 2 is hinged to the saddle box 1 by a pivot 4. The other end of the female swing arm 2 is hinged to one end of the male swing arm 3 by a pivot 4. The other end of the male swing arm 3 is fixedly connected to the traction box 5. The volume of the male swing arm 3 is smaller than the volume of the receiving groove.

[0022] By adopting the technical solution of this utility model, when it is necessary to use a protective cover to shield a vehicle or to store the protective cover from the vehicle surface, it is only necessary to hang a partial area of ​​the protective cover on one of the connecting rods. Through the cooperation of the rotating movements of multiple connecting rods, the protective cover is pulled to achieve the folding and unfolding of the protective cover. After the protective cover is stored, the sub-arm can rotate and be accommodated in the receiving groove of the mother arm, thereby reducing the overall volume of this utility model. When this utility model moves with the vehicle, it enables the vehicle to easily pass through the height restriction frame set on the road.

[0023] Specifically, the cross-section of the female swing arm 2 is U-shaped. Preferably, C-shaped steel can be used instead of female swing arm 2.

[0024] In addition, the compact robotic arm-type vehicle shield retraction device also includes a main support tube 6 and multiple sub-support tubes 7. The sub-support tubes 7 are stacked together, with one sub-support tube 7 also fitted inside the main support tube 6. The main support tube 6 is also fixedly connected to the traction box 5, which is equipped with a cylinder 8. One of the sub-support tubes 7 is also fixedly connected to the piston rod of the cylinder 8. Using the technical solution of this utility model, the main support tube 6 and the multiple sub-support tubes 7 form a telescopic structure, enabling it to pull a larger area of ​​the protective shield, thus allowing the protective shield to cover more sides of the vehicle and effectively expanding the shield's coverage area.

[0025] In addition, the compact robotic arm-type vehicle shield retraction device also includes pipe sections 9, and there are two or more main support pipes 6. The pipe sections 9 are fixed between two main support pipes 6 of the same diameter, or the pipe sections 9 are fixed between two secondary support pipes 7 of the same diameter. Both the main support pipes 6 and the secondary support pipes 7 are circular steel pipes.

[0026] Furthermore, the saddle box 1 is equipped with multiple swing arm motors 10. The output shaft of each swing arm motor 10 is fixedly connected to the drive sprocket 11, and the rotating shaft 4 is also fixedly connected to the driven sprocket 12 in a corresponding manner. Each drive sprocket 11 and each driven sprocket 12 are also connected together by a chain 13. The saddle box 1 is also fixedly connected to a slider 19, which is mounted on a guide rail 14. The guide rail 14 is also fixedly connected to a saddle frame 15, which is fixedly connected to the vehicle. The saddle frame 15 is generally U-shaped and is fixedly connected to the left and right sides and the top surface of the vehicle. The saddle box 1 is also equipped with a shift motor 16. The output shaft of the shift motor 16 is fixedly connected to the drive gear 17. The saddle frame 15 is also fixedly connected to a rack 18, and the drive gear 17 and the rack 18 mesh with each other. By adopting the technical solution of this utility model, the shifting motor 16 can also drive the saddle box 1 to move along the guide rail 14, thereby further expanding the pulling area of ​​the protective cover and enabling the protective cover to provide more comprehensive shielding protection for the vehicle.

[0027] Specifically, the compact robotic arm-type vehicle shield retraction and extension device provided by this utility model includes the following steps: I. Covering and Shading Stage: Step P1: Provide a protective net and a vehicle, with one side of the protective net as the towing side and the other side as the positioning side, and one side of the vehicle as the starting side and the other side as the ending side; then fold the protective net and place it on the starting side of the vehicle, with the towing side above the positioning side. Step P2: Move the traction box 5 to the starting side of the vehicle; Step P3: Attach the traction side of the protective netting to the traction box 5; Step P4: Move the traction box 5 along the outbound trajectory from the starting side of the vehicle to the ending side of the vehicle, and at the same time move the traction side of the protective net cover from the starting side of the vehicle to the ending side of the vehicle. Step P5: After separating the traction side of the protective net cover from the traction box 5, fix the traction side of the protective net cover to the termination side of the vehicle. Step P6: Move the traction box 5 along the return trajectory from the end side of the vehicle to the starting side of the vehicle, and at the same time, spread the protective net cover out smoothly, and then fix the positioning side of the protective net cover to the starting side of the vehicle. II. Collection and Dismantling Phase: Step Q1: Separate the traction side of the protective net from the termination side of the vehicle, and simultaneously separate the positioning side of the protective net from the starting side of the vehicle. Step Q2: Move the traction box 5 to the end side of the vehicle; Step Q3: Attach the traction side of the protective netting to the traction box 5; Step Q4: Move the traction box 5 from the end side of the vehicle to the start side of the vehicle, and at the same time move the traction side of the protective net cover from the end side of the vehicle to the start side of the vehicle. Step Q5: Separate the traction side of the protective net cover from the traction box 5; Step Q6: Gather and remove the protective netting.

[0028] Specifically, in step P2, after the traction box 5 is moved to the starting side of the vehicle, the traction box 5 is first extended and unfolded to the left and right sides before proceeding to the next step.

[0029] The technical solution of this utility model achieves the folding and unfolding of the protective net cover through the flipping motion of the main swing arm and the auxiliary swing arm. During the unfolding process, the saddle box continuously pulls and guides the protective net cover. After the protective net cover is fully unfolded, the saddle box also applies force to the protective net cover to ensure smooth unfolding and prevent local wrinkles from appearing on the unfolded protective net cover. Similarly, during the folding process, the saddle box continuously pulls and guides the protective net cover to prevent local areas of the protective net cover from stopping and causing jamming. This ensures smooth deployment and retraction of the protective netting, increasing the success rate. Furthermore, the rotational movement of the main and auxiliary swing arms enables the retraction and deployment of the protective netting. Compared to the common method of using rollers for winding or unfolding in existing technologies, the main and auxiliary swing arms have a larger range of motion, making them suitable for protecting and concealing large vehicles. In addition, the saddle box can use its own shape to support local areas of the protective netting, and in conjunction with the surface paint color of the protective netting, it creates the illusion of a mountain to outsiders, achieving camouflage and concealment of the vehicle.

[0030] Specifically, during step P4, while the traction box 5 moves along the outward trajectory, the angle between the mother swing arm 2 and the daughter swing arm 3 continuously changes between 0° and 180°. During step P5, after the traction side of the protective netting is fixed to the vehicle's termination side, the left and right sides of the traction box 5 are first shortened and retracted before proceeding to the next step. Using the technical solution of this utility model, because the traction box 5 is telescopic, the protective netting can cover not only the left and right sides of the vehicle but also the front and rear sides, improving the vehicle's concealment and expanding the coverage area of ​​the protective netting.

[0031] Furthermore, during step P6, as the traction box 5 moves along the return trajectory, the angle between the mother swing arm 2 and the daughter swing arm 3 continuously changes between 0° and 180°. During steps P2, P4, P6, Q2, or Q4, the mother swing arm 2, daughter swing arm 3, and traction box 5 simultaneously move along the guide rail 14. By adopting the technical solution of this utility model, the relative positions of the saddle box 1, mother swing arm 2, and daughter swing arm 3 with the vehicle change accordingly, further expanding the protective netting's coverage area, thereby adapting to the comprehensive coverage of large-sized special vehicles or military vehicles and improving the camouflage and concealment performance of the protective netting.

[0032] Furthermore, the masking phase also includes the following steps: When performing step P1, a stationary position is also set on the surface of guide rail 14; When performing step P6, after the positioning side of the protective netting is fixed to the starting side of the vehicle, the mother swing arm 2, the daughter swing arm 3 and the traction box 5 are first moved to the stationary position, and then the traction box 5 is used to support and bulge a local area of ​​the protective netting.

[0033] When performing step Q2, after moving the traction box 5 to the end side of the vehicle, first extend and unfold the traction box 5 to the left and right sides before proceeding to the next step.

[0034] When performing step Q5, after separating the traction side of the protective net cover from the traction box 5, first shorten and fold the left and right sides of the traction box 5 before proceeding to the next step.

[0035] Specifically, the spreading and masking stage also includes the following steps: When performing step P1, a stationary workstation is also set on the surface of the guide rail 14; The retraction and removal phase also includes the following steps: When performing step Q6, after the protective net cover is retracted and removed, first move the traction box 5 to the stationary position, then reduce the angle between the mother swing arm 2 and the daughter swing arm 3 to 0°, and then reduce the angle between the mother swing arm 2 and the vehicle top surface to 0°. The stationary position is located at the center of mass along the length of the guide rail 14.
