Description

Technical Field

[0001] This utility model relates to the field of vehicle parts technology, specifically to a spare tire rack mechanism and a bus having the same. Background Technology

[0002] Buses are typically equipped with spare tire racks to store and secure the spare tire, ensuring a quick and safe replacement in the event of a tire failure. Traditional spare tire racks are usually fixed structures, securing the spare tire to the vehicle's chassis.

[0003] However, due to the weight and low installation position of the spare tire, fixed spare tire racks require multiple people to work together to load and unload the spare tire, which is time-consuming and labor-intensive. In addition, different car models have different chassis spaces, and fixed spare tire racks cannot be adapted to the installation requirements of different car models. If a suitable spare tire rack is to be provided for different car models, it is necessary to carry out special customization or modification, which increases production costs. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A spare tire rack mechanism, including a bracket;

[0007] The bracket is slidably mounted on the chassis frame of the vehicle. The bracket is provided with a storage platform for placing the spare tire and a fixing component for fixing the spare tire. Multiple fixing components are provided.

[0008] A handle is provided on one side of the bracket, and an arc-shaped baffle is provided on the other side of the bracket.

[0009] Preferably, the chassis frame is provided with a mounting bracket, the mounting bracket is provided with a slide rail, and the bracket is disposed on the slide rail;

[0010] The slide rail is equipped with a locking device.

[0011] Preferably, the slide rail includes an inner slide rail, a middle slide rail, and an outer slide rail that are slidably sleeved together in sequence. The outer slide rail is fixedly mounted on the mounting bracket, and the bracket is mounted on the inner slide rail.

[0036] Example 1

[0037] Please refer to Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides a spare tire carrier mechanism, including a bracket 10; the bracket 10 is slidably mounted on the chassis frame 20 of the vehicle, and the bracket 10 is provided with a storage platform (not shown in the figure) for placing the spare tire 40 and a fixing member (not shown in the figure) for fixing the spare tire 40, and multiple fixing members are provided; a handle 101 is provided on one side of the bracket 10, and an arc-shaped baffle 102 is provided on the other side of the bracket 10.

[0038] Specifically, the bracket 10 is connected to the chassis frame 20 via a slide rail 202. When the spare tire 40 is installed, it can be placed on the storage platform of the bracket 10 and securely locked in place by fasteners. The operator simply pushes the handle 101 to easily slide the bracket 10 into the chassis frame 20. Conversely, when the spare tire 40 needs to be removed, the operator pulls the handle 101 in the opposite direction, and the bracket 10 slides smoothly out along the slide rail 202. After the fasteners are unlocked, the spare tire 40 can be easily removed. This not only simplifies the loading and unloading process of the spare tire 40 and improves operational convenience, but also saves manpower and time. At the same time, the sliding bracket 10 design is more flexible and can adapt to the chassis space of different vehicle models, saving production costs.

[0039] In addition, an arc-shaped baffle 102 is provided on the other side of the bracket 10. The shape of the arc-shaped baffle 102 matches the outer edge of the spare tire 40. The arc-shaped baffle 102 can be used to position the spare tire 40, ensuring that the spare tire 40 is placed accurately on the storage platform, and to prevent the spare tire 40 from shifting when it is fixed later, thus improving stability.

[0040] like Figure 1 and Figure 2 As shown, in this embodiment, a mounting bracket 201 is provided on the chassis frame 20, and a slide rail 202 is provided on the mounting bracket 201. The bracket 10 is mounted on the slide rail 202. The slide rail 202 is provided with a locking element (not shown in the figure) for locking or unlocking the slide rail 202. The locking element can lock and unlock the slide rail 202 by manual operation or electric drive, such as bolts, latches, spring locks or pneumatic locks, thereby realizing quick locking and unlocking of the bracket 10.

[0041] Specifically, the slide rail 202 includes an inner slide rail 2021, a middle slide rail 2022, and an outer slide rail 2023 that are slidably mounted in sequence. The outer slide rail 2023 is fixedly mounted on the mounting bracket 201, and the bracket 10 is mounted on the inner slide rail 2021. The slide rail 202 has a three-section design. When the bracket 10 is pulled, the inner slide rail 2021, the middle slide rail 2022, and the outer slide rail 2023 unfold sequentially, providing sufficient extension and retraction space. When the slide rail 202 is fully extended or completely closed, it can be manually or automatically locked to facilitate the loading and unloading of the spare tire 40 by the operator.

[0042] A plurality of first ball bearings 2024 are disposed between the inner slide rail 2021 and the middle slide rail 2022, and a plurality of second ball bearings 2025 are disposed between the middle slide rail 2022 and the outer slide rail 2023. The first ball bearings 2024 and the second ball bearings 2025 can be solid steel balls, thereby reducing frictional resistance during the extension and retraction of the slide rail 202, improving sliding smoothness, and extending the service life of the slide rail 202. In a preferred embodiment, the slide rail 202 can be an A2576 heavy-duty industrial guide rail.

[0043] like Figure 1 As shown, in this embodiment, the bracket 10 is provided with multiple rollers 103, which are equidistantly arranged to form a storage platform. The rollers 103 support the weight of the spare tire 40, and the number and spacing of the rollers 103 can be adjusted according to actual design requirements. By arranging multiple rollers 103 at intervals, the stability of the support for the spare tire 40 can be ensured while reducing the overall structural weight, making it easier for personnel to push and pull the bracket 10.

[0044] In this embodiment, the fastener is a fixing bolt or a fixing strap. In a preferred embodiment, the fastener is a snap-on polyester strap. The high strength of polyester enhances the stability of the spare tire 40. The snap-on design makes it easy for operators to quickly fix and loosen the spare tire 40, further improving loading and unloading efficiency and ease of operation, and making it convenient for single-person operation.

[0045] like Figure 1 As shown, in this embodiment, the arc-shaped baffle 102 is provided with a number of weight-reducing holes 1021. By designing the weight-reducing holes 1021, the weight of the overall structure is reduced, making it easier for people to push and pull the bracket 10 with less effort.

[0046] like Figure 3 As shown, this embodiment also includes a luggage rack 30, which is mounted on the chassis frame 20 and located above the bracket 10. The luggage rack 30 is used to hold luggage or other items. The luggage rack 30 can be fixedly mounted on the chassis frame 20 or can be slidably mounted on the chassis frame 20 via guide rails to facilitate the retrieval of luggage.

[0047] Example 2

[0048] A passenger vehicle is also provided, including the spare tire carrier mechanism described in Embodiment 1. The spare tire 40 can be fixed on the bracket 10 of the spare tire carrier mechanism, and the bracket 10 can be pushed into the chassis frame 20 to a predetermined position to realize the installation of the spare tire 40; the spare tire 40 can be removed by pulling out the bracket 10, which is convenient to operate and effectively improves loading and unloading efficiency.

[0049] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations 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. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
