Description

Technical Field

[0001] This utility model belongs to the field of bus technology, specifically relating to a spare tire bracket for urban buses. Background Technology

[0002] Currently, spare tire brackets for buses are mostly concentrated in the front or rear areas; however, the dense assemblies at the front or rear of the vehicle and the limited space make it easy for the spare tire brackets to interfere with other critical equipment. Therefore, when customers have specific configuration requirements, the presence of spare tire brackets often forces a significant adjustment to the overall vehicle layout, which significantly increases the design difficulty, prolongs the design verification cycle, and limits the flexibility of the design.

[0003] In addition, the existing spare tire brackets are generally complex in structure, which increases manufacturing costs and weight, and the process of taking out and putting in the spare tire is cumbersome and laborious, which seriously affects efficiency when changing tires in an emergency. Utility Model Content

[0004] The purpose of this utility model is to provide a spare tire bracket for urban buses, which solves the technical problems of poor layout flexibility, complex structure and inconvenient access in the existing technology.

[0005] This utility model discloses a spare tire bracket for urban buses. The urban bus has a frame-type frame, and the frame has an outer opening on one side in the width direction to form a receiving chamber. The spare tire bracket includes: Multiple support beams extend horizontally along the length of the vehicle frame and are arranged laterally at intervals along the width of the vehicle frame. They are fixedly installed at the bottom of the accommodating compartment to support the bottom of the horizontally placed spare tire. Multiple limiting rods are vertically installed in the accommodating chamber and located above the supporting beam to abut against the inner wall of the spare tire, thereby restricting the spare tire from moving inward. Two tow hooks are fixedly connected to both sides of the accommodating chamber along the length of the vehicle frame; A restraint strap, detachably connected between the two tow hooks, is used to fit against the outer sidewall of the spare tire to restrict outward movement of the spare tire.

[0006] This application utilizes the unused width space of the vehicle frame to form an outer-opening storage compartment, thereby breaking through the limitations of traditional front / rear layouts and completely avoiding interference with key assemblies. This reduces design difficulty, shortens the design verification cycle, and expands design flexibility. Through a triple-coordinated restraint system consisting of static load-bearing support beams, rigid inner contact of limit rods, and elastic restraint of outer restraint straps, the structure is simplified while ensuring stable fixation of the spare tire under bumpy and turning conditions, thus guaranteeing driving safety. The side-mounted tire access within the storage compartment, combined with the detachable design of the restraint straps and tow hooks, makes the operation of taking and placing the spare tire convenient and quick, requiring no complicated tools or cumbersome steps, saving time and labor costs, and improving replacement efficiency.

[0007] Based on the above technical solution, the solution of this application can be further improved as follows: Preferably, it further includes: A rolling shaft extends horizontally along the length of the vehicle frame and is rotatably mounted at the bottom of the compartment near the opening to provide rolling support when the spare tire is pushed into the compartment. This design greatly reduces the friction when the spare tire is pushed in and taken out, allowing operators to easily load and unload the spare tire and further improve the efficiency of spare tire replacement.

[0008] Preferably, the top height of the rolling shaft is higher than the top surface height of the support beam; this solution significantly reduces frictional resistance, allowing operators to more easily pick up and put down the spare tire, thus reducing the difficulty and complexity of the operation.

[0009] Preferably, it further includes: Two support blocks are fixedly connected to the outer side of the outermost support beam, and each end of the rolling shaft is rotatably connected to one of the support blocks. This solution provides stable support for the rolling shaft from both ends, ensuring that the rolling shaft can be stably installed at the bottom of the accommodating chamber near the opening. The rotatable connection also ensures that the rolling shaft can rotate freely and flexibly, and enhances the stability and reliability of the overall structure.

[0010] Preferably, it further includes: Two support mechanisms are respectively located at both ends of the rolling shaft and are detachably connected to the adjacent support blocks. This solution provides a stable support for the rolling shaft, ensuring its accurate positioning and stable rotation. Furthermore, due to its detachable nature, it can be easily and quickly disassembled, thereby greatly improving the convenience and flexibility of maintenance.

[0011] Preferably, the support mechanism includes: A fixing plate is fixedly installed on the support block; The movable plate is bolted to the fixed plate; The support shaft is fixedly installed on the movable plate; The bearing is coaxially embedded at the end of the rolling shaft and movably sleeved on the support shaft. This solution can effectively reduce the frictional resistance when the rolling shaft rotates, reduce wear, improve the smoothness and reliability of operation, and extend the service life of the equipment.

[0012] Preferably, the limiting rod has two rods, which are symmetrically fixedly connected to the top surface of the innermost support beam. With this solution, the abutment force on the inner wall of the spare tire is evenly distributed, which can more reliably restrict the spare tire from moving inward. It works in concert with the support beam to provide stable support and effective limiting for the spare tire, ensuring that the spare tire is placed securely in the storage room.

[0013] Preferably, the limiting rod has a cylindrical structure; with this solution, the spare tire will not be damaged by bumps or knocks from the edges, and the risk of the limiting rod breaking due to collision is reduced, ensuring that the limiting rod has a stable and reliable limiting effect on the spare tire.

[0014] Through the above technical solution, this utility model achieves the following beneficial effects: 1. This application utilizes the unused width space of the vehicle frame to form an externally open accommodating compartment, thereby breaking through the limitations of traditional front / rear layout, completely avoiding interference with key assemblies, thus reducing design difficulty, shortening the design verification cycle, and expanding design flexibility; 2. This application achieves stable fixation of the spare tire under bumpy and turning conditions by using a triple synergistic limiting mechanism consisting of static load bearing of the support beam, rigid contact of the limiting rod with the inner side, and elastic constraint of the restraint strap on the outer side. This simplifies the structure and ensures driving safety. 3. This application utilizes a side-mounted tire retrieval system within the compartment, along with a detachable design for the restraint straps and tow hooks. This design makes the retrieval and placement of the spare tire convenient and quick, eliminating the need for complex tools or cumbersome procedures, thus saving time and labor costs and improving replacement efficiency.

[0016] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

They are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] In this application, unless otherwise expressly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0019] To better understand the above technical solutions, the following will provide a detailed description of the technical solutions in conjunction with the accompanying drawings and specific embodiments.

[0020] Example: like Figures 1-5 As shown in the figure, this application discloses a spare tire bracket for urban buses, which is used to support and fix the spare tire. It has the advantages of good layout flexibility, simple structure and convenient use.

[0021] The city bus has a frame-type chassis 1. In this design, a storage compartment 101 with an outer opening is formed on one side of the chassis 1 in the width direction. This compartment provides a dedicated storage space for the spare tire, and the outer opening facilitates the entry and exit of the spare tire. It should be noted that the above design utilizes the structural characteristics of the city bus frame 1, using the unused space within the frame 1 to place the spare tire. This design is less likely to interfere with other critical equipment, making the presence of the spare tire bracket have almost no impact on the overall vehicle structure. Therefore, it is not necessary to make significant adjustments to the overall vehicle layout, which significantly reduces the design difficulty, shortens the design verification cycle, improves the design flexibility, and ensures the consistency and reliability of the entire vehicle.

[0022] The spare tire bracket structure includes: multiple support beams 2, multiple limiting rods 3, two tow hooks 4, and restraint straps 5, and its specific design is as follows.

[0023] Multiple support beams 2 extend horizontally along the length of the frame 1 and are arranged laterally at intervals along the width of the frame 1. They are fixedly installed at the bottom of the storage chamber 101 to support the bottom of the horizontally placed spare tire and to evenly distribute the weight of the spare tire, providing stable and reliable support for the spare tire and ensuring that the spare tire is stably placed in the storage chamber 101.

[0024] For example, the number of support beams 2 is four, which improves the lightweight effect while ensuring the stability of the support. However, it is not limited to this and the number can also be any number.

[0025] Multiple limiting rods 3 are vertically installed inside the accommodating chamber 101 and located above the supporting beam 2. They are used to abut against the inner wall of the spare tire to restrict the spare tire from moving inward, thereby ensuring the stability of the spare tire's position inside the accommodating chamber 101 and preventing the spare tire from colliding or interfering with other parts of the vehicle. They can also serve as a positioning reference for the inner side of the spare tire, helping the operator to determine whether the spare tire has been pushed in properly.

[0026] Two tow hooks 4 are fixedly connected to both sides of the frame 1 along the length of the compartment 101. They are used to provide a stable connection position for the restraint straps 5, so that the restraint straps 5 can play an effective role. They also have a certain strength and can withstand the tension generated by the restraint straps 4 when fixing the spare tire, thus ensuring the reliability of the entire fixing system.

[0027] The restraint strap 5 is detachably connected between the two tow hooks 4 and is used to fit against the outer wall of the spare tire to restrict the spare tire from moving outward. This works in conjunction with the limit rod 3 to form a two-way restraint on the spare tire in the horizontal direction. The detachable design makes the installation and removal of the spare tire easier, saves time and labor costs, and improves the efficiency of bus operation.

[0028] This utility model has the following technical effects: 1. By utilizing the unused width space of the frame 1, an externally open accommodating chamber 101 is formed, thereby breaking through the limitations of the traditional front / rear layout, completely avoiding interference with key assemblies, thus reducing design difficulty, shortening the design verification cycle, and expanding design flexibility. Second, by using the triple coordinated limiting mechanism consisting of the static load-bearing support beam 2, the rigid contact of the limiting rod 3 with the inner side, and the elastic constraint of the restraint strap 5 with the outer side, the spare tire is stably fixed under bumpy and turning conditions while simplifying the structure, thus ensuring driving safety. Third, the spare tire can be retrieved from the side of the compartment 101. With the detachable design of the restraint straps 5 and the tow hooks 4, the operation of retrieving and placing the spare tire is convenient and quick, without the need for complicated tools or cumbersome steps, saving time and labor costs and improving replacement efficiency.

[0029] In some embodiments, such as Figure 3-4 As shown, it also includes: A rolling shaft 6, which extends horizontally along the length of the frame 1 and is rotatably mounted at the bottom of the compartment 101 near the opening, is used to provide rolling support when the spare tire is pushed into the compartment 101.

[0030] When the operator pushes the spare tire into the storage compartment 101, the bottom of the spare tire contacts the rolling shaft 6. The rolling shaft 6 converts sliding friction into rolling friction by rolling, which greatly reduces the frictional resistance when pushing the spare tire in, making it easier and less strenuous for the operator to push the spare tire into the storage compartment 101, especially for heavier bus spare tires. Similarly, when taking out the spare tire, the rolling shaft 6 can also play the same auxiliary role, making it easier to pull the spare tire out of the storage compartment.

[0031] By setting up the rolling shaft 6, the friction force when pushing in and taking out the spare tire is greatly reduced, allowing operators to easily complete the loading and unloading of the spare tire and further improving the efficiency of spare tire replacement.

[0032] In this embodiment, as Figure 2As shown, the top height of the rolling shaft 6 is higher than the top surface height of the support beam 2. Therefore, during the process of loading or unloading the spare tire, the operator can adjust the posture of the spare tire to raise its inner side, so that the spare tire does not contact the support beam 2, but is only supported on the rolling shaft 6. Since the friction between the spare tire and the rolling shaft 6 is rolling friction, it greatly reduces the frictional resistance compared to the sliding friction generated when the spare tire directly contacts the support beam 2. This allows the operator to complete the loading and unloading of the spare tire more easily, reducing the difficulty and complexity of the operation.

[0033] In this embodiment, as Figure 3-4 As shown, it also includes: Two support blocks 7 are fixedly connected to the outer side of the outermost support beam 2, and the two ends of the rolling shaft 6 are rotatably connected to one support block 7.

[0034] By setting support blocks 7, a stable support is provided for the rolling shaft 6 from both ends, ensuring that the rolling shaft 6 can be stably installed at the bottom of the accommodating chamber 101 near the opening. The rotatable connection method ensures that the rolling shaft 6 can rotate flexibly and freely, and also enhances the stability and reliability of the overall structure.

[0035] Based on the above embodiments, such as Figure 2 As shown, it also includes: Two support mechanisms 8 are respectively located at both ends of the rolling shaft 6 and are detachably connected to the adjacent support block 7.

[0036] By setting up the support mechanism 8, a solid support is provided for the rolling shaft 6, ensuring that it is accurately positioned and maintains a stable rotation state. Furthermore, due to its detachable nature, it can be easily and quickly disassembled and separated, thereby greatly improving the convenience and flexibility of maintenance.

[0037] For example, such as Figure 3 As shown, the support mechanism 8 includes: The fixing plate 81 is fixedly installed on the support block 7, specifically located on the inner side of the support block 7, and plays a role in structural reinforcement and positioning; The movable plate 82 is bolted to the fixed plate 81 and is located on the side of the fixed plate 81 away from the support block 7, which facilitates the individual disassembly and assembly of the rolling shaft 6, improving flexibility and maintainability. The support shaft 83 is fixedly installed on the movable plate 83 and serves to support the rolling shaft 6. Specifically, it can be threaded, which improves the stability of the connection. The bearing 84 is coaxially embedded at the end of the rolling shaft 6 and movably sleeved on the support shaft 83, and can rotate freely relative to the support shaft 83, thereby reducing friction.

[0038] The design of the support mechanism 8 described above can effectively reduce the frictional resistance when the rolling shaft 6 rotates, reduce wear, improve the smoothness and reliability of operation, and extend the service life of the equipment.

[0039] In some embodiments, such as Figure 1 and Figure 2 As shown, there are two limiting rods 3, which are symmetrically fixedly connected to the top surface of the innermost support beam 2.

[0040] The above design utilizes a symmetrical layout to distribute the contact force of the limiting rod 3 against the inner wall of the spare tire evenly, which can more reliably restrict the spare tire from moving inward. Furthermore, by fixing it to the top surface of the innermost support beam 2, it not only ensures the limiting function but also works synergistically with the support beam 2 to provide stable support and effective limiting for the spare tire, ensuring that the spare tire is placed securely in the storage room.

[0041] In some embodiments, such as Figure 1 and Figure 2 As shown, the limiting rod 3 has a cylindrical structure.

[0042] With the above settings, the outer surface of the cylindrical structure is smooth, so the spare tire will not be damaged by bumps on the edges and corners. At the same time, it reduces the risk of the limit rod 3 breaking due to collision, and ensures that the limit rod 3 has a stable and reliable limiting effect on the spare tire.

[0043] Further explanation regarding this application: When placing the spare tire, first open the outer opening of the compartment 101 to ensure that the interior space of the compartment 101 can accommodate the spare tire normally; push the spare tire horizontally into the compartment 101, so that the bottom of the spare tire rests stably on the multiple support beams 2 for stable support, until the inner wall of the spare tire abuts against the multiple limiting rods 3, thereby restricting the spare tire from moving inward; then connect the two ends of the restraint straps 5 to the two tow hooks 4 respectively, and adjust the tightness of the restraint straps 5 so that they can fit tightly against the outer wall of the spare tire, thereby effectively restricting the spare tire from moving outward. If the compartment 101 has an openable cover or other structure, close and lock the cover to ensure that the spare tire is not affected by external factors (such as rain, dust, etc.) during vehicle operation, and to ensure the safety of the spare tire placement.
