Description

Technical Field

[0001] This utility model belongs to the technical field of bus parts and components, specifically relating to a bus air duct luggage rack assembly structure. Background Technology

[0002] In the passenger transport sector, including highway passenger buses and tour buses, luggage racks and air conditioning ducts are two key onboard facilities. Luggage racks are mainly used to store passengers' carry-on luggage and need to have sufficient load-bearing capacity and structural stability; air conditioning ducts are responsible for evenly distributing the hot and cold air generated by the overhead air conditioner to all areas of the passenger compartment, directly affecting passenger comfort.

[0003] Currently, most buses on the market use separate designs and installations for their luggage racks and air conditioning ducts. This traditional structure has several drawbacks: First, separate installation requires separate mounting brackets and installation space on the roof of the vehicle, which not only occupies a significant amount of roof space, limiting the storage capacity of the luggage rack or resulting in insufficient duct cross-sectional dimensions, affecting ventilation efficiency, but also increases the overall weight of the vehicle. Second, the installation process is cumbersome, requiring separate positioning and fixing of the luggage rack and air duct, which not only increases labor costs and assembly time, but also easily leads to structural inconsistencies due to positioning errors during the two installations, affecting the aesthetics of the entire vehicle interior. Third, when the luggage rack is carrying luggage, if the bus is in motion... The bumps and vibrations can easily cause resonance, which not only generates noise and affects the passenger experience, but may also cause the luggage rack connection parts to loosen due to long-term vibration, posing a safety hazard. At the same time, the independent air duct structure lacks effective buffering and shock absorption design, and may also have problems such as poor sealing and air leakage at the joints of the air duct panels under vibration, affecting the working efficiency of the air conditioning system. Fourth, the decoration and functionality of traditional luggage racks are relatively simple, usually with only a simple baffle structure, and the air conditioning vents and lighting devices are mostly arranged independently, further occupying the cabin space and making it difficult to achieve an integrated interior style.

[0004] With the increasing demands for lightweight design, integration, comfort, and safety in the bus industry, traditional independent luggage racks and air duct structures can no longer meet market requirements. Therefore, developing a combined structure that can organically integrate luggage racks and air conditioning ducts, while also providing shock absorption, integrated lighting and air outlet functions, and convenient installation and maintenance, has become an urgent technical problem to be solved in the field of bus interior design.

[0006] A passenger vehicle air duct luggage rack assembly structure includes a hanging bracket. Several parallel hanging brackets are connected by U-shaped storage panels, with the storage panels contacting the inner side of the hanging brackets at open ends. The storage panels are limited on the hanging brackets by an upper limiting mechanism. A lower profile retaining strip is fixed to the lower part of the hanging bracket at the open end by screws. The lower edge of the storage panel is fixed to the lower profile retaining strip by screws, and an upper profile retaining strip is fixed to the upper edge of the storage panel by screws. The lower part of the hanging bracket is fixed with screws. The device includes a first air duct profile clip and a second air duct profile clip. A lower profile decorative panel is clipped between the lower profile clip and the first air duct profile clip. A main air duct plate is clipped between the first air duct profile clip and the second air duct profile clip. A top-mounted air conditioning outlet lighting unit is installed on the main air duct plate. A secondary air duct plate is clipped into a groove on the side surface of the second air duct profile clip, and the edge of the secondary air duct plate is fixed to the hanger with screws. A buffer is installed on the outer side of the middle part of the hanger, and a shock absorber is installed in the middle part of the hanger.

[0007] Preferably, the lower profile clip has a slot, and a lower light strip plate is engaged in the slot. The lower light strip plate is used to display the seat number.

[0008] Preferably, the upper profile clip has two slots, one slot is fitted with an upper light strip plate, and the other slot is fitted with an upper profile decorative plate for covering screws.

[0009] Preferably, the limiting mechanism includes a limiting groove and a limiting pin. The limiting groove is disposed at the upper part of the opening end of the hanger, and the limiting pin is disposed at the upper part of the shelf. The limiting pin is inserted into the limiting groove to limit the shelf on the hanger.

[0010] Preferably, the shelf is further provided with a folded edge on the outside of the limiting pin, the folded edge being used to fix the upper profile clip.

[0011] Preferably, the buffer includes a first damper with both ends rotatably mounted on the outer side of the middle part of the hanger, the first damper is fitted with a first spring, and the two ends of the first spring are welded and fixed to the two ends of the first damper.

[0012] Preferably, the damping component includes a guide rod welded to the middle of the hanger, a damping ball movably mounted outside the guide rod, and second dampers distributed in a ring array welded to the upper and lower surfaces of the damping ball, respectively. The telescopic part of the second damper is fixed to the hanger, and a second spring is sleeved on the second damper, with the end of the second spring welded and fixed to the hanger.

[0013] Preferably, a total of six second dampers are welded to the surface of the shock-absorbing ball, and the six second dampers are divided into two groups, one group located on the upper surface of the shock-absorbing ball and the other group located on the lower surface of the shock-absorbing ball.

[0014] Preferably, the upper profile clip, lower profile clip, storage plate, lower profile decorative plate, main air duct plate and secondary air duct plate form an air conditioning duct with the bus body.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (i) Achieve structural integration, optimize space utilization and lightweighting

[0017] This structure organically integrates the luggage rack and air conditioning duct into one unit. Through the coordinated operation of structural components such as the hanger, upper profile clips, lower profile clips, first air duct profile clips, and second air duct profile clips, the storage space of the luggage rack is formed by the shelf. At the same time, the shelf, lower profile decorative panel, main air duct panel, and secondary air duct panel, together with the bus body, form the air conditioning duct. This integrated design eliminates the need for separate mounting brackets and space for the luggage rack and air duct. On the one hand, it greatly saves installation space on the roof of the passenger compartment, significantly increasing the storage capacity of the luggage rack within the same vehicle body size, while ensuring that the air conditioning duct has sufficient cross-sectional dimensions to ensure ventilation volume and air delivery efficiency. On the other hand, the integrated structure reduces redundant brackets and connecting parts, effectively reducing the weight of the entire vehicle, which is in line with the development trend of lightweight buses. It also reduces the load on the vehicle body and extends the service life of the vehicle body.

[0018] (ii) Simplify the installation process and improve assembly efficiency and aesthetics.

[0019] This structure employs a modular installation method combining snap-fit ​​and screw fixing. The upper part of the shelf is positioned on the hanger via limiting pins and grooves. The upper profile clip is fixed to the shelf with screws, the lower profile clip is fixed to the hanger with screws, and the lower part of the shelf is fixed to the lower profile clip with screws. Major components such as the upper light strip panel, upper profile decorative panel, lower light strip panel, lower profile decorative panel, main air duct panel, and secondary air duct panel are all installed by snap-fit ​​with their corresponding profile clips, with screws used only for auxiliary fixing in critical areas. This design significantly simplifies the installation process, eliminating the need for separate positioning and installation of the luggage rack and air ducts, reducing assembly steps and labor costs, while also minimizing installation errors caused by multiple positioning steps, ensuring assembly accuracy between components. Furthermore, the upper profile decorative panel conceals the screws connecting the upper profile clip and the shelf, while the lower profile decorative panel further optimizes the structure's appearance, making the interior style of the entire combined structure more unified, simple, and aesthetically pleasing, thus enhancing the overall quality of the bus interior.

[0020] (III) Enhance buffering and shock absorption performance to improve safety and stability

[0021] The buffer installed on the outer side of the middle section of the luggage rack effectively cushions the downward pressure transmitted from the storage panel when the luggage rack is loaded with luggage, preventing excessive localized stress and deformation of the rack due to concentrated luggage weight. Simultaneously, the shock absorber installed in the middle of the rack absorbs and mitigates vibrations during bus operation, effectively reducing resonance between the luggage rack and the air duct structure. This not only reduces noise from vibrations but also prevents loosening of connections and wear of components caused by long-term vibrations. This design significantly improves the safety of luggage stored on the luggage rack, preventing luggage from slipping due to vibrations. It also ensures the stability of the air conditioning duct structure, preventing seal failure and air leakage at the joints of the duct panels due to vibrations, thus ensuring the normal operation of the air conditioning system.

[0022] (iv) Integrating multiple functions to enhance ride comfort and practicality

[0023] This structure achieves multiple functional integrations: the upper light strip plate, which is snapped into the upper profile clip, combines with the roof-mounted air conditioning vent lighting unit installed on the main air duct plate, integrating lighting and air conditioning functions into one unit. This eliminates the need for separate lighting fixtures and air conditioning vents, further saving space in the passenger compartment. The roof-mounted air conditioning vent lighting unit allows air conditioning air to be delivered directly and evenly into the passenger compartment, improving air conditioning efficiency and passenger comfort. Furthermore, the combination of snap-fit ​​and screw fixing for each component not only facilitates installation but also makes future maintenance and replacement convenient. When a component is damaged, it can be quickly disassembled and replaced, reducing maintenance costs.

[0024] (v) Improve structural strength and reliability

[0025] Multiple hangers are arranged in parallel and form a stable frame structure with the storage plate and air duct plate through upper and lower profile clips, which significantly improves the load-bearing capacity and structural strength of the entire combined structure and can meet the load-bearing requirements of bus luggage racks. At the same time, the various clip-on parts fit tightly and the screw fixing parts are firmly connected, ensuring the reliability of the structure under long-term use and vibration environment, and effectively extending the service life of the product.

[0041] Specifically, the shelf 4 is provided with a folded edge 42 on the outside of the limiting pin 41, and the folded edge 42 is used to fix the upper profile clip 2.

[0042] In this embodiment, the upper profile clip 2 is fixed to the folded edge 42 with screws. The upper profile clip 2 is fixed to the folded edge 42 with screws, which makes it easy to disassemble the upper profile clip 2 and makes after-sales maintenance more convenient.

[0043] Specifically, the buffer 14 includes a first damper 141 with both ends rotatably mounted on the outer side of the middle part of the hanger 1. A first spring 142 is sleeved on the first damper 141, and the two ends of the first spring 142 are welded and fixed to the two ends of the first damper 141.

[0044] In this embodiment, a buffer 14 is formed by a first damper 141 and a first spring 142. The two ends of the first damper 141 are rotatably mounted on the outer side of the middle part of the hanger 1, so that when the lower part of the hanger 1 deforms, the first damper 141 can be buffered by its extension or compression.
