Description

Technical Field

[0001] This utility model relates to the technical field of camping trailer towing devices, and in particular to a pressure-protected camping trailer towing device. Background Technology

[0002] A camping trailer towing device is a device specifically designed to connect a vehicle to a camping trailer, ensuring safe and stable towing.

[0003] However, existing camping trailer towing devices can usually only provide front-to-back buffer protection at the connection point. When moving in camping areas, there are usually many slopes, and the connection point needs to swing up and down frequently, which can easily cause damage and reduce its service life.

[0004] Therefore, a pressure-protected camping trailer towing device has now been developed that can cushion and protect the connection points during swinging, thereby reducing wear at the connection points and increasing service life. Utility Model Content

[0005] To overcome the shortcomings of existing camping trailer towing devices, which typically only provide front-to-back cushioning protection at the connection point, and which are prone to damage due to frequent up-and-down swinging during movement in camping areas, resulting in a reduced service life, this invention provides a pressure-protected camping trailer towing device that can cushion the connection point during swinging, thereby reducing wear and tear and extending service life.

[0006] The technical implementation scheme of this utility model is as follows: a pressure-protected camping trailer towing device, including a connector, a universal tow device, elastic elements, a mounting frame, a fixing frame, a damper, a linear spring, a slider, a support frame, and a buffer assembly. The universal tow device is installed at the rear of the connector. The mounting frame is connected to the universal tow device by a damping rotatable connection. Multiple elastic elements are connected between the mounting frame and the universal tow device. The damper is rotatably connected to the rear side of the mounting frame. A linear spring is installed inside the damper. The fixing frame is connected to the rear of the damper. The slider is connected to the rear side of the fixing frame. The support frame is connected to the slider by a damping sliding connection. The support frame is provided with a buffer assembly that can enhance the buffering effect between the support frame and the connector.

[0007] Optionally, the elastic element is a torsion spring.

[0008] Optionally, it also includes fasteners, with fasteners connected to the rear sides of both the left and right sides of the support frame.

[0009] Optionally, mounting holes are provided on both the left and right sides of the fastener.

[0010] Optionally, it also includes a connecting shaft and a first telescopic spring. The connecting shaft is connected to the rear side of the slider, and the connecting shaft is connected to the support frame through a damped sliding connection. The first telescopic spring is connected between the connecting shaft and the support frame.

[0011] Optionally, the buffer assembly includes a guide rod, a sliding frame, a connecting frame, a connecting rod, and a second telescopic spring. The rear of the support frame is connected to the guide rod, and the left and right sides of the guide rod are connected to the sliding frame via damping sliding. The left and right sides of the slider are connected to the connecting frame, and the connecting frame is rotatably connected to the adjacent sliding frame via a connecting rod. The sliding frame is connected to the support frame via a second telescopic spring.

[0012] Beneficial effects: 1. When encountering a slope, the connector drives the universal traction device to swing up and down and rotate. The force of the torsion spring buffers and dampens the universal traction device and the mounting frame, thus achieving the effect of buffering and protecting the connection when swinging, so as to reduce wear at the connection and improve service life.

[0013] 2. This utility model moves the connecting frame while the slider moves, causing the connecting rod to push the sliding frame along the guide rod. The second telescopic spring buffers and dampens the sliding frame, achieving multi-stage buffering and damping between the connecting parts and the support frame, thus preventing damage to the connection between the connecting parts and the support frame due to pressure.

[0020] The above-described solution will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of this application. The implementation conditions used in the embodiments may be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally those in routine experiments.

[0021] A pressure-protected camping trailer towing device, such as Figures 1-5 As shown, the assembly includes a connector 1, a universal traction device 2, elastic elements, a mounting bracket 3, a fixing bracket 4, a damper 5, a linear spring 51, a slider 6, a support bracket 7, a fixing element 8, a connecting shaft 9, a first telescopic spring 10, and a buffer assembly. The universal traction device 2 is mounted on the rear of the connector 1. The mounting bracket 3 is rotatably connected to the universal traction device 2 via damping. Two elastic elements, torsion springs 21, connect the mounting bracket 3 and the universal traction device 2. The damper 5 is rotatably connected to the rear of the mounting bracket 3. The linear spring 51 is installed inside the damper 5. The fixing bracket 4 is connected to the rear of the damper 5. The slider 6 is connected to the rear of the fixing bracket 4. The support bracket 7 is slidably connected to the slider 6 via damping. The fixing element 8 is connected to the rear of both the left and right sides of the support bracket 7. The fixing member 8 has mounting holes on both its left and right sides for easy installation and fixing. The connecting shaft 9 is connected to the rear side of the slider 6. The connecting shaft 9 is connected to the support frame 7 by a damped sliding connection. The first telescopic spring 10 is connected between the connecting shaft 9 and the support frame 7. The support frame 7 is provided with a buffer assembly, which includes a guide rod 11, a sliding frame 12, a connecting frame 13, a connecting rod 14, and a second telescopic spring 15. The guide rod 11 is connected to the rear of the support frame 7. The sliding frame 12 is connected to both its left and right sides by a damped sliding connection. The connecting frame 13 is connected to both the left and right sides of the slider 6. The connecting rod 14 is rotatably connected between each connecting frame 13 and the adjacent sliding frame 12. The second telescopic spring 15 is connected between each sliding frame 12 and the support frame 7.

[0022] When using this utility model, firstly, the connector 1 is installed on the universal traction device 2, then the connector 1 is connected to the vehicle. The support frame 7 is connected to the camping trailer via the fixing member 8, allowing the camping trailer to move and pull the vehicle. When encountering a slope, the connector 1 drives the universal traction device 2 to swing and rotate up and down. The force of the torsion spring 21 buffers and dampens the universal traction device 2 and the mounting frame 3, thus providing cushioning protection at the connection point during swinging, reducing wear at the connection point, and improving service life. When the camping trailer approaches the vehicle, the damper 5 and the linear spring 51... The impact between the mounting bracket 3 and the fixed bracket 4 is absorbed and buffered. The slider 6 slides on the support bracket 7. The impact between the slider 6 and the support bracket 7 is absorbed and buffered by the force of the first telescopic spring 10. When the slider 6 moves, it drives the connecting bracket 13 to move, so that the connecting rod 14 pushes the sliding bracket 12 to move along the guide rod 11. The second telescopic spring 15 buffers and dampens the sliding bracket 12, thereby achieving multi-stage buffering and damping between the connecting member 1 and the support bracket 7, and avoiding damage to the connection between the connecting member 1 and the support bracket 7 due to pressure.
