Description

Technical Field

[0001] This utility model relates to the field of spare tire loading and unloading technology, and more specifically, to a spare tire flipping mechanism and a vehicle. Background Technology

[0002] For special vehicles such as fire trucks, some models may require additional equipment to retrieve heavy items like spare tires due to design limitations or user requests to reduce the workload on personnel. Currently, some models on the market utilize electrical and hydraulic systems installed inside the cargo compartment to achieve this by using methods such as direct tilting, extension, and lifting to retrieve the spare tire.

[0003] The inventors discovered that commercially available spare tire flipping mechanisms are generally large in size, resulting in a large flipping radius and significantly reducing cargo space. Therefore, there is an urgent need for a compact spare tire flipping mechanism. Utility Model Content

[0004] The purpose of this utility model is to provide a spare tire flipping mechanism and a vehicle, which has a compact structure and can avoid a large amount of space being occupied in the vehicle compartment.

[0005] The embodiments of this utility model can be implemented as follows:

[0006] In a first aspect, this utility model provides a spare tire flipping mechanism, comprising:

[0007] Base;

[0008] The first arm is hinged at one end to the base near the edge of the carriage;

[0009] The second arm is hinged to the end of the first arm, and the second arm always remains vertical under the action of gravity.

[0010] A connector, located on the second arm section, is used for detachably connecting the spare tire;

[0011] A driving component, disposed on the base and connected to the first arm section, is used to drive the first arm section to swing about its hinge axis with respect to the base.

[0012] In an optional embodiment, an L-shaped auxiliary arm is connected to the side of the first arm near the spare tire. The auxiliary arm is also hinged to the base, and the hinge axis of the first arm and the base, as well as the hinge axis of the auxiliary arm and the base, coincide.

[0013] In an optional embodiment, the connector includes a fixed flange that is detachably connected to the spare tire by bolts.

[0014] In an optional embodiment, the first arm section and the second arm section are offset from each other, and the fixing flange is located on the side of the second arm section away from the first arm section.

[0015] In an optional embodiment, the drive component includes a mounting rod and a telescopic cylinder. The mounting rod is vertically disposed at one end of the base away from the edge of the carriage, and the telescopic cylinder is hinged to the mounting rod, with its end hinged to the first arm section.

[0016] In an optional embodiment, the spare tire flipping mechanism further includes a support frame disposed on the base, the support frame being used to support the spare tire, and the surface of the support frame having an arc surface adapted to the spare tire.

[0017] In an optional embodiment, the flipping mechanism further includes a locking member disposed on the base, the locking member being used to limit the spare tire when the spare tire is located on the support frame.

[0018] In an optional embodiment, the locking member includes a limiting seat disposed on the base, the limiting seat having a receiving groove opening toward the auxiliary arm, the limiting seat being used to prevent the first arm from continuing to rotate away from the edge of the carriage when the spare tire is on the support frame.

[0019] In an optional embodiment, the locking member further includes a limiting rod and a locking rod. The limiting rod is vertically disposed on the base, and the locking rod is detachably inserted into the limiting rod. A through hole is provided on the second arm for the locking rod to pass through.

[0020] Secondly, this utility model provides a vehicle, including a cargo compartment, a spare tire, and a spare tire flipping mechanism as described in any of the foregoing embodiments. The spare tire flipping mechanism is disposed inside the cargo compartment, and the spare tire is detachably disposed on the flipping mechanism.

[0021] The beneficial effects of the spare tire flipping mechanism and vehicle provided by this utility model embodiment include:

[0022] By setting up a base, a first arm, and a second arm, the spare tire is mounted on the second arm via a connector. A drive mechanism drives the first arm to swing outwards from the vehicle compartment until it extends beyond the compartment, completing the tire flipping. Since the second arm is hinged to the first arm and remains vertical, the first arm does not need to fully flip to near the ground during swing; it only needs to extend vertically downwards to near the ground, at which point the spare tire is mounted on the second arm. Therefore, the first arm requires only a small flipping radius to flip the spare tire close to the ground, resulting in a compact overall structure and reduced space occupation within the vehicle compartment.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0030] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0031] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0032] In the description of this utility model, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product is usually placed during use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0033] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0034] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0035] When a vehicle experiences a tire blowout or leak while driving, it will be unable to drive safely if it does not have a spare tire. It will often be stranded and await assistance, which can significantly impact the vehicle's occupants and other vehicles on the road. Therefore, a spare tire is considered an important safety feature, and it is generally recommended that vehicles carry a spare tire to ensure travel safety. Regarding spare tire installation, for unibody vehicles, they are usually concealed under the floor inside the trunk or directly suspended from the rear of the vehicle; for body-on-frame vehicles, they are usually suspended from the rear of the chassis frame or mounted on the back of the vehicle.

[0036] For special vehicles such as fire trucks, some models may require equipment for retrieving heavy items like spare tires due to design limitations or user requests to reduce the workload on personnel. Because of the unique structure of these vehicles, the original spare tire mounting location is unsuitable; therefore, the equipment must be placed inside the vehicle's cargo compartment. Some models already utilize electrical and hydraulic systems installed inside the cargo compartment, employing methods such as direct flipping, extension, and lifting to retrieve the spare tire. However, current spare tire flipping devices, especially those using direct flipping, are generally large in size and have a high center of gravity. This affects vehicle stability and further encroaches on the already limited cargo space, preventing the installation of other equipment.

[0037] To address the aforementioned technical problems, this utility model provides a spare tire flipping mechanism and vehicle, which has a compact structure and avoids significantly encroaching on vehicle compartment space. The overall structure, working principle, and technical effects of the spare tire flipping mechanism and vehicle provided by this utility model are described in detail below through embodiments and with reference to the accompanying drawings.

[0038] Please refer to Figure 1 This utility model provides a vehicle having a cargo compartment 100, a spare tire 200, and a spare tire flipping mechanism 300. The spare tire 200 is located inside the cargo compartment 100, and the spare tire flipping mechanism 300 is also located inside the cargo compartment 100. The spare tire 200 is detachably mounted on the spare tire flipping mechanism 300. The spare tire 200 is transferred from inside the cargo compartment 100 to outside the cargo compartment 100 through the spare tire flipping mechanism 300, thereby realizing the flipping of the spare tire 200.

[0039] Please refer to Figures 1-2 This utility model also provides a spare tire flipping mechanism 300, applied to the aforementioned vehicle, for flipping and moving the spare tire 200 inside the vehicle compartment 100 to the outside of the vehicle compartment 100, so as to facilitate the replacement of the spare tire 200. The spare tire flipping mechanism 300 provided by this utility model has the advantages of compact overall structure and avoiding occupying a large amount of space in the vehicle compartment 100 while meeting the flipping radius requirements.

[0040] This utility model provides a spare tire tilting mechanism 300, comprising a base 310, a first arm 320, a second arm 330, a connector 340, and a drive component 350. The base 310 is installed inside the vehicle body 100. Specifically, the base 310 is detachably installed to the surface of the bottom frame of the vehicle body 100 by bolts, and the base 310 is close to the edge of the vehicle body 100. One end of the first arm 320 is hinged to the end of the base 310 near the edge of the vehicle body 100, and the first arm 320 can swing about its hinge axis with the base 310 in the direction of entering or leaving the vehicle body 100. The second arm 330 is hinged to the end of the first arm 320, and the second arm 330 remains vertical during the swinging of the first arm 320 under the action of gravity. The connector 340 is disposed on the second arm 330, and the spare tire 200 is detachably connected to the second arm 330 through the connector 340. The drive unit 350 is mounted on the base 310 and is connected to the first arm 320. The drive unit 350 is used to drive the first arm 320 to swing.

[0041] By setting up a base 310, a first arm 320, and a second arm 330, the spare tire 200 is mounted on the second arm 330 via a connector 340. A drive unit 350 drives the first arm 320 to swing outwards from the vehicle compartment 100 until it extends beyond the compartment 100, completing the flipping of the spare tire 200. Since the second arm 330 is hinged to the first arm 320 and remains vertical, the first arm 320 does not need to fully flip to near the ground when swinging; it only needs to extend vertically downwards to near the ground, at which point the spare tire 200 is mounted on the second arm 330 near the ground. Therefore, the first arm 320 only requires a small flipping radius to flip the spare tire 200 to near the ground, making the overall structure of the spare tire flipping mechanism 300 compact and reducing its space occupation in the vehicle compartment 100.

[0042] Furthermore, by setting a second arm 330 to shorten the length of the first arm 320, the center of gravity of the spare tire 200 is lower during the flipping process, thus improving the vehicle's stability during the flipping process.

[0043] Please refer to Figure 3 To improve the structural stability of the first arm section 320, an auxiliary arm section 321 is provided on the side of the first arm section 320 near the spare tire 200. The auxiliary arm section 321 is L-shaped, with its horizontal section fixedly connected to the first arm section 320, and its vertical section extending towards the base 310 and hinged to the base 310. Furthermore, to ensure smooth rotation of the first arm section 320, the hinge axis between the first arm section 320 and the base 310, and the hinge axis between the auxiliary arm section 321 and the base 310, coincide. By providing the auxiliary arm section 321, the structural stability of the first arm section 320 is improved.

[0044] It is understood that in this embodiment, the base 310 is made of steel square tube or steel plate by bending and welding, resulting in a robust structure; the first arm 320 and the second arm 330 are both made of steel square tube or steel plate by welding. In other embodiments, the base plate, the first arm 320, and the second arm 330 can also be made of other materials, as long as their structural strength meets the stress requirements when the spare tire 200 is flipped.

[0045] Please refer to Figure 3 and Figure 4To enable the second arm section 330 to rotate relative to the first arm section 320, the first arm section 320 and the second arm section 330 are offset from each other, with a certain gap between them. The first arm section 320 and the second arm section 330 rotate relative to each other via a pivot. This ensures that the second arm section 330 will not interfere with the first arm section 320 during rotation, guaranteeing that the second arm section 330 can always rotate relative to the first arm section 320 and remain vertical. Furthermore, the connecting component 340 includes a fixing flange 341, which is installed on the side of the second arm section 330 opposite to the first arm section 320. The fixing flange 341 is compatible with the spare tire 200, and the fixing flange 341 and the spare tire 200 are detachably connected by bolts.

[0046] Please refer to Figure 3 The drive unit 350 includes a mounting rod 351 and a telescopic cylinder 352. The mounting rod 351 is vertically fixed to the end of the base 310 away from the edge of the carriage 100. The telescopic cylinder 352 is mounted on the top of the mounting rod 351, and its end is hinged to the first arm section 320. By extending or retracting the piston rod of the telescopic cylinder 352, the first arm section 320 is driven to swing. It is understood that in order to drive the first arm section 320 to rotate downwards and extend towards the ground so that the spare tire 200 is close to the ground, the connection height of the telescopic cylinder 352 on the mounting rod 351 is greater than the connection height of the telescopic cylinder 352 on the first arm section 320. Furthermore, to minimize the length of the telescopic cylinder 352, it is hinged to the end of the first arm section 320 near the base 310.

[0047] Understandably, in order to improve the structural strength of the mounting rod 351, a diagonal brace connected to the mounting rod 351 is also provided on the base 310 to support and reinforce the mounting rod 351 and improve its structural stability.

[0048] Please refer to Figure 3 and Figure 4 To support the spare tire 200 and ensure the structural stability of the spare tire flipping mechanism 300 during vehicle movement, in this embodiment, the spare tire flipping mechanism 300 also includes a support frame 360. The support frame 360 ​​is mounted on the base 310 and faces the spare tire 200, and is used to support the spare tire 200. To improve the support effect of the support frame 360 ​​on the spare tire 200, the surface of the support frame 360 ​​also has an arc surface 361 adapted to the spare tire 200, thereby increasing the contact area between the spare tire 200 and the support frame 360 ​​when the spare tire 200 is located on the support frame 360.

[0049] Please refer to Figure 3 and Figure 4To prevent the spare tire 200 from moving relative to the vehicle compartment 100 due to vehicle vibration during movement, which could lead to a collision between the spare tire 200 and the vehicle compartment 100, and relative displacement of the first arm 320 and the second arm 330 relative to the vehicle compartment 100, thereby causing damage to the spare tire 200, the vehicle compartment 100, and the spare tire tilting mechanism 300, this embodiment includes a locking member on the base 310. When the spare tire 200 is located on the support frame 360, the locking member is used to limit and fix the spare tire 200, preventing relative movement of the spare tire 200 during vehicle movement, improving the safety of the spare tire 200 and the vehicle compartment 100, and enhancing the structural stability of the spare tire tilting mechanism 300.

[0050] Please refer to Figure 3 and Figure 4 The locking component includes a limiting seat 370, which is disposed on the base 310. The limiting seat 370 has a receiving groove 371, which is U-shaped and its opening faces the auxiliary arm 321. When the first arm 320 rotates to the position of the spare tire 200 on the support frame 360, the auxiliary arm 321 is located in the receiving groove 371 and abuts against the bottom wall of the receiving groove 371, thereby preventing the first arm 320 from continuing to rotate away from the edge of the carriage 100. To avoid a violent collision between the auxiliary arm 321 and the limiting seat 370 when it rotates into the receiving groove 371, flexible materials such as rubber pads can be laid on the inner wall of the receiving groove 371 for cushioning.

[0051] Please refer to Figure 3 and Figure 4 The locking mechanism also includes a limiting rod 380 and a locking rod (not shown in the attached diagram). The limiting rod 380 is vertically mounted on the base 310. When the spare tire 200 is located on the support frame 360, the second arm 330 is vertical and located on the same vertical plane as the limiting rod 380. A through hole is provided on the limiting rod 380 in the horizontal direction. The locking rod can be detachably inserted into the limiting rod 380 through the through hole. A through hole is provided on the second arm 330 that corresponds to the through hole on the limiting rod 380. When the spare tire 200 is located on the support frame 360, the locking rod is passed through the limiting rod 380 and the second arm 330 to achieve the limiting and fixing of the second arm 330.

[0052] By setting a locking component, the first arm 320 and the second arm 330 are limited and fixed when the spare tire 200 is on the support frame 360, thereby preventing the first arm 320 and the second arm 330 from rotating relative to the vehicle during vehicle movement, thus fixing the spare tire 200 and preventing the spare tire 200 from being damaged by collision during vehicle movement.

[0053] In summary, the implementation principle of the spare tire flipping mechanism 300 and the vehicle provided by this utility model is as follows: the spare tire flipping mechanism 300 is provided with a base 310, a first arm 320 and a second arm 330. The spare tire 200 is installed on the second arm 330 through a connector 340. The first arm 320 is driven by the drive unit 350 to swing outward toward the outside of the vehicle compartment 100 until the first arm 320 extends outward of the vehicle compartment 100, thus completing the flipping of the spare tire 200. Since the second arm 330 is hinged to the first arm 320 and the second arm 330 is always in a vertical position, the first arm 320 does not need to be fully rotated to near the ground when it swings. The second arm 330 only needs to extend vertically downwards to near the ground. At this time, the spare tire 200 is installed on the second arm 330 near the ground. Thus, the first arm 320 only needs a small rotation radius to rotate the spare tire 200 to near the ground, making the overall structure of the spare tire rotation mechanism 300 compact and reducing the space occupied by the spare tire rotation mechanism 300 in the vehicle compartment 100.

[0054] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
