Description

Technical Field

[0001] The invention belongs to the technical field of automobile heating, and in particular relates to an automobile heater installation structure and an automobile. Background Art

[0002] In the cold winter, in order to provide passengers with a better riding experience, a heater is usually installed in the car. Affected by the structural space of the car, the existing car heater is usually arranged under the car seat, aiming to spread the warm air more effectively through the rising characteristics of the hot air flow, and deliver warm air to the feet of the passengers. The heater of this design often protrudes on the floor, which not only affects the shape and function of the car seat, making it not beautiful, but also reduces the activity space of the passenger's legs, affecting the passenger's riding comfort; and the high-temperature gas of the heater blows directly to the passenger's legs and feet. Although it can quickly increase the temperature in this area and bring warmth to the passengers, after a long time, the passengers can clearly feel the temperature difference between the legs and feet and other parts of the body. The legs and feet are blown hot by the hot air, but they cannot avoid it due to the limitation of the space in the car, making the riding experience extremely poor. In addition, the installation structure of this traditional heater cannot meet the requirements of energy saving, emission reduction and lightweight of automobiles due to its large overall volume and heavy weight. Summary of the invention

[0003] The object of the present invention is to provide a car heater installation structure and a car, which forms a step structure through a double-layer floor, and the heater is installed in the step space. The high-temperature gas of the heater is blown out from the air outlet on the vertical side wall of the step, and the car seat is installed on the upper honeycomb floor of the step structure. The footrest support frame provides support strength for the passenger footrest, which can prevent the hot air blown by the heater from directly blowing on the legs and feet, thereby improving the comfort of the passengers; the height of the step structure can be adjusted according to the height of the heater, and the application range is wide; the step structure of the double-layer floor of the present invention is more beautiful and increases the leg activity space of the passengers; compared with the installation method of installing the heater under the seat, the installation structure of the heater of the present invention will not affect the shape and function of the car seat, and can improve the riding comfort of the passengers; the installation structure of the double-layer floor of the present invention adopts aluminum alloy material and honeycomb floor, and achieves the purpose of energy saving, emission reduction and lightweight of the car under the premise of ensuring the support strength.

[0004] The specific contents of the plan are as follows:

[0005] A car heater installation structure includes a double-layer floor structure, the double-layer floor structure includes an upper floor and a lower floor, the upper floor is a two-level step structure when viewed from the side, and the lower floor is approximately an L-shaped structure when viewed from the side, the upper floor is fixedly connected to the lower floor to form a step structure with a hollow cavity, an air outlet is provided on the vertical end surface of the upper floor, and the lower floor includes a heater installation frame, which is arranged in the accommodating space formed by the upper floor and the lower floor and is adjacent to the corresponding air outlet.

[0006] The present invention is applicable to buses, especially small buses. In cold winter, the doors of buses are opened from time to time during driving due to passengers getting on and off the bus, which reduces the temperature inside the bus, especially the lower limbs of passengers will feel cold obviously. In order to solve this problem and provide passengers with a better riding experience, traditional buses usually install a heater under the car seat, and the air supply port of the heater is set behind the legs of the passengers, and the heater blows hot air directly to the legs and feet. Although such a design can rapidly increase the temperature of the lower limbs of passengers, the heater blows directly at a close distance, which will cause local overheating of the lower limbs when the passengers sit for a long time, and the passengers cannot avoid the air supply port due to the limitation of the space in the car, which makes the passenger's riding experience worse. The step structure composed of the double-layer floor structure of the present invention changes the installation position and air supply position of the heater, which can not only use the rising characteristics of the hot air flow to heat the lower limbs of passengers, but also will not blow directly to make passengers feel uncomfortable, and at the same time, it can also expand the leg activity space of passengers, improve the aesthetics and comfort of the bus seats, and can achieve the purpose of lightweighting and reducing emissions of automobiles.

[0007] The lower floor of the double-layer floor structure is a part of the white body floor of the automobile. It realizes the overall performance of the white body of the automobile and realizes the functions of fixing the heater and sealing the passenger compartment. The upper floor is fixedly connected to the lower floor, which is approximately an L-shaped structure in side view, to form a step structure. An air outlet is provided on the vertical end surface of the upper floor. The heater mounting frame is fixedly connected to the accommodation space formed by the upper floor and the lower floor. The heater is fixedly mounted on the heater mounting frame and the air supply port and the air outlet of the heater are adjacent. The height of the upper floor can be adjusted according to the height of the heater, which can be applied to heaters of different heights and has a wider range of applications. The car seat is arranged on the step, and the passenger sits on the car seat with his feet stepping on the upper honeycomb floor of the step. When the heater delivers hot air, the hot air blows out from the air outlet, which can provide hot air for the passenger's feet without directly blowing the passenger's legs and feet, greatly improving the passenger's riding comfort.

[0008] The lower floor panel of the double-layer floor structure is made by aluminum plate bending process. The upper and lower ends of the lower floor panel are provided with horizontal folding edges, and the middle part is inclined to form a rectangular folded plate with a Z-shaped structure when viewed from the side.
