Description

Technical Field

[0001] This utility model relates to a spare tire rack, and more particularly to an electric roll-up spare tire rack. Background Technology

[0002] With the increasing popularity of RV travel culture, users have placed higher demands on the convenience, comfort, and safety of RVs. In RV usage scenarios, the efficiency and convenience of loading and unloading the spare tire directly affect the user's emergency response capabilities and travel experience.

[0003] Currently, the RV industry commonly uses mechanically bolted spare tire racks. These racks consist of a metal bracket mounted at the rear of the RV with several fixing bolts. Loading or unloading the spare tire requires manually lifting and unloading the heavy tire (weighing tens of kilograms), precisely aligning it with the bolts, and then, under load, tightening each nut individually with a wrench to secure it. The disassembly process is equally cumbersome, requiring all nuts to be unscrewed before the spare tire can be removed. The entire process is time-consuming, labor-intensive, and demands significant physical strength from the operator, leading to widespread criticism of this traditional solution among consumers.

[0004] Solving the problems of labor-saving and automated loading and unloading of spare tires in RVs has become a key feature for enhancing the competitiveness of RV products. Utility Model Content

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1-3 As shown in the figure, this embodiment of the electric retractable spare tire carrier includes an electric winch 1 that provides power, an electric retractable arm that performs the storage and release of the spare tire 17, and a gas spring 15 that provides assistance to the electric retractable arm in releasing the spare tire 17.

[0023] In this embodiment, the electric winch 1 is fixed to the reserved mounting point at the rear of the vehicle body by bolts. The electric winch 1 has a winch rope 2 wound inside it, and the free end of the winch rope 2 is provided with a rope buckle 3 for connection.

[0024] like Figure 1 As shown, the base of the electric winch arm is the mounting base 4, which is also fixed to the vehicle body by bolts. The position of the mounting base 4 is on the matching straight extension side of the electric winch 1; combined with Figure 3 In this application example, the electric winch 1 and the mounting base 4 are arranged in a straight line along the Y-axis of the vehicle, and the retraction and extension of the electric winch arm also extends along the Y-axis; the width of the mounting base 4 matches the thickness of the spare tire 17 to better accommodate the spare tire 17, and both long sides of the mounting base 4 have upward-folding sidewalls to form a U-shaped or C-shaped support groove for supporting the bottom of the spare tire 17 when it is retracted.

[0025] A limiting support 5 is provided on the side of the mounting base 4 near the electric winch 1 within the support groove. The limiting support 5 and the arc-shaped fixing arm 9 together enclose the spare tire 17. A supporting limiting plate 6 is provided inside the limiting support 5 to abut against the spare tire 17. The supporting limiting plate 6 provides better support for the spare tire 17. Thus, as Figure 1 As shown, when the spare tire 17 is stored, its lower part is supported by the mounting base 4 and limited by the support limiting plate 6 of the limiting support 5. The remaining part of the spare tire 17 is wrapped by the retracted arc-shaped fixing arm 9, forming a stable multi-point fixation; in addition, as Figure 2 As shown, when the electric winch releases the spare tire 17, the support limit plate 6 also serves as the tensioning point for the winch rope 2; a buckle 18 is also provided on the outer plate of the limit support 5.

[0026] The main moving part of the electric roller arm is the arc-shaped fixed arm 9, such as... Figure 1 As shown, the root of the arc-shaped fixed arm 9 is movably hinged to the side wall of the mounting base 4 through the first pivot 7, so that the entire arm can be folded and rotated around the first pivot 7.

[0027] like Figure 2As shown, the arc-shaped fixed arm 9 in this embodiment includes a first segment arm 10 and a second segment arm 11 that are hinged to each other. Specifically, they are hinged to each other via a second pivot 8. This two-segment hinge design allows the second segment arm 11 to fold downwards when unfolded, so that the contact guard plate 16 at its end can smoothly contact the ground, thereby realizing the function of safely placing the spare tire 17 from a high place to the ground. At the same time, the contact guard plate 16 protects the life of the electric retractor arm.

[0028] To further prevent the mechanism from loosening due to vibration during vehicle operation, a hook plate 19 matching the buckle 18 is installed on the outer plate surface of the other free end of the second segment arm 11. The buckle 18 and the hook plate 19 cooperate to lock. That is to say, when the arc-shaped fixed arm 9 is tightened to the storage position, the operator can manually fasten the buckle 18 and the hook plate 19 to achieve locking, which greatly improves safety.

[0029] Based on the above structure and combined Figure 2 As shown, the first segmented arm 10 and the second segmented arm 11 each include two identical arm plates 12. The two arm plates 12 of the same group are parallel and spaced apart, and several connecting rods 13 are connected between them to enhance the structural stability of the first segmented arm 10 and the second segmented arm 11. At the same time, the connecting rods 13 are important components for limiting the position of the spare tire 17.

[0030] A seat plate 14 is provided between the two arm plates 12 at the free end of the first segment arm 10 near the first pivot 7. When the spare tire 17 is released, the seat plate 14 also serves as the tensioning point of the winch rope 2.

[0031] This embodiment also includes a gas spring 15, which achieves the purpose of saving effort. The end of its cylinder is hinged to a pre-set support on the mounting base 4 via a pin, while the end of its piston rod is hinged to a seat plate 14 fixed to the root of the first segmented arm 10 via a pin. The gas spring 15 provides assistance when the arc-shaped fixed arm 9 is flipped up and provides damping when it is lowered, thereby making the entire action process smooth and controllable.

[0032] In actual use, the release process of spare tire 17 is as follows: The operator first unlocks the latch 18 and hook 19; by controlling the switch, the electric winch 1 can be started remotely or by wire, so that it slowly releases the winch rope 2; under the pressure release of the cylinder of the gas spring 15, the arc fixed arm 9 begins to fold downward around the first pivot 7. As the winch rope 2 continues to be released, the first segment arm 10 and the second segment arm 11 unfold relative to each other around the second pivot 8 until the contact guard plate 16 at the end of the second segment arm 11 is fully supported on the ground.

[0033] At this point, the spare tire 17 also descends to the ground, and the operator can easily move it laterally out of the extended arm.

[0034] In actual use, the storage process for the Spare Tire 17 is as follows: The operator rolls the spare tire 17 into the unfolded second segment arm 11, and starts the electric winch 1 through the control switch to tighten the winch rope 2. The tension of the winch rope 2 acts on the arc-shaped fixed arm 9 and pulls it to fold upward around the first rotating shaft 7. During this process, the gas spring 15 is compressed. The arc-shaped fixed arm 9 gradually hugs the spare tire 17 and lifts it until the bottom of the spare tire 17 falls completely into the support groove of the mounting base 4. At this time, the tire tread of the spare tire 17 is still in contact with the support limiting plate 6 in the limiting support 5. Finally, the buckle 18 and the hook 19 are manually fastened to complete the locking and storage.

[0035] This application discloses an electric retractable spare tire rack, driven by an electric winch and assisted by a gas spring, completely eliminating the tedious steps of manual lifting and tool disassembly, allowing for operation by a single person. When the spare tire is in the stowed state, it is supported and positioned by the mounting base and limiting support, with the arc-shaped fixing arm locking it from above. A secondary locking mechanism using buckles and hooks ensures that the spare tire does not wobble or make abnormal noises during vehicle operation. The segmented design of the arc-shaped fixing arm allows the spare tire to land smoothly when released, making loading and unloading effortless. It balances safety and practicality while improving the overall user experience of the RV.

[0036] The above embodiments are not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present utility model are also within the protection scope of the present utility model.
