Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to a step component, a step assembly, and a bus. Background Technology

[0002] In northern regions, winter temperatures are low. Because the bus steps are close to the doors and the doors open and close frequently, the temperature of the steps is close to the ambient temperature. In icy or snowy weather, snow can accumulate under passengers' feet in the steps, causing ice to form on the floor. This can significantly impact the safety of passengers getting on and off the bus, posing a major safety hazard.

[0003] In existing technology, vehicle steps are typically made of a single steel plate welded to the vehicle body, bent into a stepped shape. By installing a heater in the step area, with the heater installed on the side of the step area away from the door and the air outlet facing the door, and ventilation openings on the step corresponding to the heater's air outlets, and air vent grilles installed at the ventilation openings, the heater and air vent grilles are located on the inner and outer sides of the step, respectively. This method of blowing air to warm the step area prevents ice from forming on the floor surface of the vehicle's step area, thus avoiding safety accidents.

[0004] However, in existing technologies, installing a heater and grille requires two operators to simultaneously align the heater and grille with the mounting holes on the steps. Then, the same fastener is used to sequentially pass through the grille, the mounting holes on the steps, and the heater to secure them to the steps. Because two people are needed to work together, the installation is cumbersome. Furthermore, when the heater needs repair or maintenance, removing the fasteners will cause the grille to loosen. After repair or maintenance, it is still necessary to align the heater and grille with the mounting holes on the steps again. This process is complex, time-consuming, and labor-intensive. Utility Model Content

[0005] The purpose of this utility model is to provide a step assembly that solves the problem in the prior art where the air outlet grille needs to be disassembled and reassembled simultaneously when removing and installing the heater at the step, which is complicated, time-consuming, and labor-intensive. The purpose of this utility model is also to provide a step assembly that solves the aforementioned technical problems by using the above-mentioned step assembly.

[0043] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0044] To address the technical problems existing in the prior art, the inventive concept of this utility model is to set up a heater mounting plate for installing the heater and a grille mounting plate for installing the grille, so that the heater and the grille can be installed on different mounting plates. In this way, the heater and the grille can be installed separately, and the grille will not come loose at the same time when the heater is removed. This solves the problem of complicated operation and time-consuming and laborious operation when installing and removing the heater at the step.

[0045] Based on the above concept, this utility model provides several different embodiments of step assemblies for illustration.

[0046] In a basic embodiment, such as Figure 1-4 As shown, the step assembly includes a step component 1, a heater 6 and a grille 7 mounted on the step component 1. The step component 1 includes a vertically arranged heater mounting plate 2. The heater mounting plate 2 is provided with a heater mounting structure for fixing the heater 6 and an air passage for communicating with the air outlet of the heater 6 so that the warm air blown out by the heater 6 can pass through. The step component 1 also includes a grille mounting plate 3 provided on the heater mounting plate 2 for the side near the door. The grille mounting plate 3 is provided with a grille mounting structure for fixing the grille 7 and an air outlet 303 for the warm air to blow out of the grille 7. An air outlet cavity is formed between the grille mounting plate 3 and the heater mounting plate 2.

[0047] By installing the heater 6 and the grille 7 on different mounting plates, the heater and grille can be installed separately, and the grille will not come loose at the same time when the heater is removed. This solves the problem of complicated operation and time-consuming and laborious operation when installing and removing the heater at the step.

[0048] Based on the above embodiments, in one embodiment, such as Figure 5-7 As shown, the heater mounting plate 2 has extension plates 202 extending toward the grille mounting plate 3 on both sides. The extension plates 202 extend to both sides of the grille mounting plate 3, and the heater mounting plate 2 and the grille mounting plate 3 together form an air outlet cavity. In another embodiment, the grille mounting plate has extension plates extending toward one side of the heater mounting plate on both sides. The extension plates extend to the surface of the heater mounting plate, and the grille mounting plate and the heater mounting plate together form an air outlet cavity.

[0049] In a preferred embodiment, such as Figure 1-4As shown, the vertical height of the air outlet 303 is less than the vertical height of the air passage 201. The grille mounting plate 3 includes a vertical plate 301 and an inclined plate 302 connected below the vertical plate 301 and gradually tilting towards the heater mounting plate 2, so that the step distance meets the usage requirements. In other embodiments, the vertical height of the air outlet on the grille mounting plate can be the same as the vertical height of the air passage on the heater mounting plate. The grille mounting plate is set as a vertical plate, and a grille matching the size of the air outlet is used. In this way, the heater and grille can be installed separately, and the grille will not come loose when the heater is removed.

[0050] In the above embodiments, both the air outlet 303 and the grille mounting structure can be mounted on the inclined plate 302. Preferably, as shown in the example... Figure 1 , 4 As shown, the air outlet 303 and the grille mounting structure are both set on the vertical plate 301. This arrangement allows the blown warm air to cover a larger area, while also increasing the space below the grille mounting plate 3, thus increasing the distance between the steps.

[0051] In the above embodiment, the warm air blown out by the heater 6 first enters the air outlet cavity and then exits from the grille 7. In a preferred embodiment, as... Figure 2 , 3 As shown in Figure 6, the step assembly 1 also includes an air guide plate 4 disposed between the heater mounting plate 2 and the grille mounting plate 3. The end of the air guide plate 4 fixed to the heater mounting plate 2 is arranged across the air passage 201. The air guide plate 4 divides the air outlet into upper and lower chambers. The air guide plate 4 includes an inclined section that gradually slopes from the air passage 201 to the air outlet 303. The air guide plate 4 also includes a horizontal section connected to the grille mounting plate 3 and a vertical section connected to the heater mounting plate 2. Through the combined action of the air guide plate 4 and the inclined plate 302 below the grille mounting plate 3, the warm air in the lower chamber is guided towards the air outlet.

[0052] Based on the above embodiments, in a preferred embodiment, such as Figure 2 , 3 As shown in Figure 6, the step assembly 1 also includes a partition 5 disposed between the heater mounting plate 2 and the grille mounting plate 3 and above the air guide plate 4. One end of the partition 5 is aligned with the upper edge of the air passage on the heater mounting plate 2, and the other end is aligned with the upper edge of the air outlet on the grille mounting plate 3 or with the edge of the uppermost air outlet on the grille 7. In this way, the partition 5 prevents warm air from blowing to the position above the grille 7 in the air outlet cavity, so that more warm air can be blown out from the grille 7.

[0053] In the above embodiments, the step assembly 1 further includes a step step. In one embodiment, the heater mounting plate 2 and the step step are integrally formed, and the grille mounting plate 3 is disposed on the side of the heater mounting plate 2 near the vehicle door, and the grille mounting plate 3 completely covers the heater mounting structure. In another embodiment, such as Figure 5 As shown, the grille mounting plate 3 is integrated with the step, and the heater mounting plate 2 is fixedly mounted on the step, with the step completely concealing the heater mounting plate 2. This ensures that the grille 7 will not detach simultaneously when the heater 6 is removed, and also conceals the heater mounting structure and provides overall aesthetic appeal.

[0054] Based on the above embodiments, the heater can be directly installed on the step assembly using bolts. Mounting holes for the bolts are provided on the heater. After placing the heater in the appropriate position, bolts are used to secure the heater to the heater mounting plate. In a preferred embodiment, such as... Figure 2-3 As shown, the heater mounting structure includes a weldable nut 8 on the heater mounting plate 2. The heater 6 is fixedly mounted on the heater mounting plate 2 by fixing bolts. The heater mounting structure also includes a weldable stud 9 on the step plate above the heater mounting plate 2. The weldable stud 9 passes through the mounting hole on the upper side of the heater 6. The nut and the weldable stud 9 work together to fix the heater 6. In this way, the heater 6 is fixed in both horizontal and vertical directions, making the heater 6 more firmly installed.

[0055] In the above embodiment, a countersunk hole is provided on the grille 7, and a threaded hole is opened in the countersunk hole for the screws for installing the grille 7 to pass through. In this way, the grille 7 is installed on the grille mounting plate 3, and the end of the screw is screwed into the countersunk hole on the grille 7 after tightening, so that the screw will not protrude from the grille 7, thus improving the aesthetics of the vehicle.

[0056] Based on the above embodiments, the step assembly 1 can be welded from multiple galvanized steel sheets and then welded as a whole to the vehicle body. In a preferred embodiment, the step assembly 1 is formed by bending and welding galvanized steel coils and then welded as a whole to the vehicle body, thereby enhancing the structural strength of the step assembly 1.

[0057] An embodiment of the bus of this utility model is as follows: the bus includes a body, a door is provided on the body, and a step assembly for passengers to get on and off is provided at the door. The structure of the step assembly is the same as that of the step assembly in any of the above embodiments, and will not be described again here.

[0058] An embodiment of the step assembly of this utility model is as follows: the step assembly has the same structure as the step assembly in the above-described step assembly embodiment, and will not be described again here.

[0059] The above description is merely a preferred embodiment of this application and is not intended to limit this application. The scope of patent protection of this application shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of this application shall also be included within the scope of protection of this application.
