Description

Technical Field

[0001] This invention relates to the field of air circulation technology for commercial vehicles, and particularly to a floor air circulation structure for commercial vehicles. Background Technology

[0002] Commercial vehicles, also known as multi-purpose vehicles, combine the functions of sedans, station wagons, and vans. They are spacious and typically feature a three-row seating layout. However, the existing air circulation systems for the second and third rows in commercial vehicles are generally located on the roof. When the air conditioning is on, hot or cold air blows downwards from the roof. Therefore, the existing air circulation systems in commercial vehicles have the following drawbacks:

[0003] When the heater is on in winter, because the density of warm air is less than that of cold air, the blown warm air will float at the top of the interior space of the van and the heat transfer process is relatively slow. Therefore, the overall temperature rises slowly in a large van. If the fan speed is turned up too high to increase the heating efficiency, it is easy to blow the air onto the passengers' heads, causing discomfort. Summary of the Invention

[0004] The purpose of this invention is to at least address one of the technical deficiencies described in the background section.

[0005] Therefore, one objective of this invention is to propose a floor air circulation structure for commercial vehicles, which aims to solve the problem that in the prior art, when commercial vehicles are heated in winter, the overall space heats up slowly, and if the airflow is increased, it is easy to blow air onto the passengers' heads, causing discomfort to the passengers.

[0006] To achieve the above objectives, one embodiment of the present invention provides a floor air circulation structure for a commercial vehicle, including an air inlet pipe and an air outlet box. One end of the air inlet pipe is fixedly connected to a U-shaped pipe, and both ends of the U-shaped pipe are fixedly connected to the air outlet box. An air inlet is provided in the air outlet box at a position corresponding to the U-shaped pipe. A motor is installed inside the air outlet box, and a screw is fixedly connected to the output end of the motor. A threaded cylinder is threadedly connected to the outer surface of the screw, and a cover plate is fixedly connected to the top end of the threaded cylinder. The motor drives the screw to rotate forward or backward within the threaded cylinder, thereby raising or lowering the cover plate. A limiting cylinder is fixedly connected to the outer surface of the motor, and a limiting rod is fixedly connected to the bottom of the cover plate. The limiting rod is inserted into the limiting cylinder to prevent the cover plate from rotating with the screw.

[0007] The beneficial effects are: First, when not in use, the motor drives the screw to rotate, causing the cover to descend and lock onto the top of the air outlet box, thus preventing dust from the floor of the commercial vehicle from entering the air outlet box and ensuring its cleanliness; Second, when the commercial vehicle is using the heater in winter, the motor drives the screw to rotate, causing the cover to rise, and the warm air circulates from the lower right to the top of the air outlet box, which can quickly heat up the space inside the commercial vehicle, and even with a strong airflow, it will not cause discomfort to passengers.

[0008] Preferably, in any of the above solutions, a reinforcing plate is fixedly connected inside the U-shaped tube.

[0009] The beneficial effect is that the U-shaped tube needs to run from in front of the second row of seats to under the second row of seats in the commercial vehicle. Therefore, passengers may step on the U-shaped tube when entering the vehicle. The reinforcement plate can reinforce the U-shaped tube area that may be stepped on, avoid the problem of poor ventilation caused by deformation of the U-shaped tube, and ensure reliability.

[0010] Preferably, in any of the above embodiments, a circular ring is fixedly connected inside the air outlet box, and two symmetrical Z-shaped grooves are formed on the outer surface of the circular ring. A plug is fixedly installed at the bottom of the motor, and two symmetrical locking blocks are fixedly connected to the bottom of the outer surface of the plug. The plug is inserted into the circular ring, and after the locking blocks align with the entrance of the Z-shaped groove, the plug is inserted into the circular ring, and the locking blocks are moved along the direction of the Z-shaped groove so that the locking blocks are engaged in the Z-shaped groove.

[0011] The beneficial effect is that when the locking block moves to the end of the Z-shaped groove, it will no longer rotate due to gravity, thus quickly fixing the motor. When the motor needs to be disassembled and maintained later, simply lift the motor up and rotate the socket to remove it, thereby facilitating disassembly and assembly and making later maintenance easier.

[0012] Preferably, in any of the above embodiments, conductive plates are fixedly connected to the bottom of the two Z-shaped grooves, and an electric contact plate is fixedly connected to the bottom of the card block. After the electric contact plate contacts the conductive plate, the motor can be connected to the power supply.

[0013] The beneficial effect is that when disassembling and assembling the motor, the motor can be directly inserted into the ring through the socket or taken out of the ring without the need for wiring or disconnection, thus further facilitating disassembly and assembly.

[0014] Preferably, in any of the above schemes, a first magnetic block is provided inside the Z-shaped groove, and a second magnetic block is fixedly connected to the top of the card block. The first magnetic block and the second magnetic block are on the same level on opposite sides. The principle of repulsion between the same level means that the first magnetic block can exert a downward force on the second magnetic block.

[0015] The beneficial effect is that after the card block is inserted into the Z-shaped groove, according to the principle of repulsion between like magnets, the first magnetic block exerts a downward force on the second magnetic block. During the operation of the commercial vehicle, it ensures that the socket can be stably inserted into the ring, thereby ensuring that the motor is always connected to the power supply and ensuring the reliability of the structure.

[0016] Preferably, as described in any of the above embodiments, the top of the cover plate has a groove, the bottom of the groove has an air inlet hole extending to the bottom of the cover plate, the perimeter of the groove has an air outlet hole, an aromatherapy tablet is placed inside the groove, and a sealing plate is fixedly installed on the top of the groove.

[0017] The beneficial effects are: by setting up the aroma diffuser, when the air outlet box is venting, the air can enter the groove through the air inlet and then be discharged from the air outlet. During this process, the air can carry away the fragrance on the aroma diffuser, thereby filling the air in the business vehicle with fragrance and enhancing the atmosphere.

[0018] Preferably, in any of the above embodiments, the bottom of the groove is fixedly connected with a plurality of protrusions.

[0019] The beneficial effect is that the protrusions create a gap between the aromatherapy tablet and the bottom of the groove, thus ensuring smooth ventilation.

[0020] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0031] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0032] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., 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 mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0033] like Figure 1-3As shown in this embodiment, a floor air circulation structure for a commercial vehicle includes an air inlet pipe 1 and an air outlet box 2. One end of the air inlet pipe 1 is fixedly connected to a U-shaped pipe 11, and the end of the air inlet pipe 1 away from the U-shaped pipe 11 is connected to the air conditioner of the commercial vehicle to achieve the circulation of cold or warm air. The U-shaped pipe 11 extends from the ground in front of the second-row seats of the commercial vehicle to the area under the two seats in the second row. Both ends of the U-shaped pipe 11 are fixedly connected to the air outlet box 2, and the air outlet box 2 has an air inlet 21 at the position corresponding to the U-shaped pipe 11. The cold or warm air generated by the air conditioner enters the air outlet box 2 through the air inlet 21. A motor 3 is installed inside the air outlet box 2, and a screw 31 is fixedly connected to the output end of the motor 3. The outer surface of the 1 is threaded with a threaded cylinder 4. The screw 31 is driven by the motor 3 to rotate forward and backward inside the threaded cylinder 4, so that the lifting tube 4 can be raised and lowered on the outer surface of the screw 31. The top of the threaded cylinder 4 is fixedly connected with a cover plate 41. By lowering the cover plate 41, it can be fastened to the top of the air outlet box 2, thereby sealing the air outlet box 2. When not in use, it can prevent dust from the floor of the commercial vehicle from entering the air outlet box 2, ensuring the cleanliness of the air outlet box 2. The outer surface of the motor 3 is fixedly connected with a limiting cylinder 32, and the bottom of the cover plate 41 is fixedly connected with a limiting rod 42. The limiting rod 42 is inserted into the limiting cylinder 32 to limit the cover plate 41 and prevent the cover plate 41 from rotating with the screw 31.

[0034] In another specific embodiment of the present invention: as follows Figure 2 As shown, a reinforcing plate 12 is fixedly connected inside the U-shaped tube 11. Because the U-shaped tube 11 needs to pass from the floor in front of the second row of seats in the commercial vehicle to the area under the seats, passengers may step on the top of the U-shaped tube 11 when they get in the vehicle. By setting the reinforcing plate 12, the part of the U-shaped tube 11 that may be stepped on can be reinforced to prevent the U-shaped tube 11 from being deformed by stepping on it and affecting the ventilation.

[0035] In another specific embodiment of the present invention: as follows Figure 4-5 As shown, a ring 22 is fixedly connected inside the air outlet box 2. Two symmetrical Z-shaped grooves 23 are opened on the outer surface of the ring 22. A plug 33 is fixedly installed at the bottom of the motor 3. Two symmetrical locking blocks 34 are fixedly connected to the bottom of the outer surface of the plug 33. The locking blocks 34 are aligned with the entrance of the Z-shaped groove 23. Then the plug 33 is inserted into the ring 22 downwards. Then the plug 33 is rotated along the trajectory of the Z-shaped groove 23. Finally, due to gravity, the locking blocks 34 fall to the end of the Z-shaped groove 23, so that the locking blocks 34 are locked in the Z-shaped groove 23. This design is convenient for disassembly and assembly.

[0036] In another specific embodiment of the present invention: as follows Figure 4-5As shown, conductive plates 24 are fixedly connected to the bottom of the two Z-shaped grooves 23. The conductive plates 24 are connected to the power supply in the commercial vehicle through cables. Contact plates 35 are fixedly connected to the bottom of the locking block 34. Contact plates 35 are electrically connected to the motor 3 through cables. After the locking block 34 is inserted into the Z-shaped groove 23, the contact plates 35 contact the conductive plates 24, thereby connecting the power supply to the motor 3. This design eliminates the need to plug and unplug the wiring of the motor 3 when disassembling and assembling the motor 3, thus facilitating the disassembly and assembly of the motor 3.

[0037] In another specific embodiment of the present invention: as follows Figure 4-5 As shown, a first magnetic block 25 is provided inside the Z-shaped groove 23, and a second magnetic block 36 is fixedly connected to the top of the locking block 34. When the locking block 34 is inserted into the Z-shaped groove 23, the first magnetic block 25 and the second magnetic block 36 are on the same level. Based on the principle of repulsion between the same level, the first magnetic block 25 can provide a downward force to the second magnetic block 36, so that the plug 33 can be stably inserted into the ring 22.

[0038] In another specific embodiment of the present invention: as follows Figure 6-7 As shown, a groove 43 is provided on the top of the cover plate 41, an air inlet 44 is provided at the bottom of the groove 43 extending to the bottom of the cover plate 41, and an air outlet 45 is provided around the groove 43. A fragrance chip 5 is placed inside the groove 43, and a sealing plate 6 is fixedly installed on the top of the groove 43. Some of the gas discharged from the air outlet box 2 can enter the groove 43 through the air inlet 44, and after taking away a certain amount of fragrance from the fragrance chip 5, it is discharged from the air outlet 45, thereby filling the air in the business vehicle with fragrance and enhancing the atmosphere.

[0039] In another specific embodiment of the present invention: as follows Figure 5 As shown, a plurality of protrusions 46 are fixedly connected to the bottom of the groove 43. The protrusions 46 can support the aromatherapy tablet 5, so that the aromatherapy tablet 5 and the bottom of the groove 43 are kept in a gap, thereby ensuring smooth gas flow.

[0040] In another specific embodiment of the present invention: as follows Figure 6-8 As shown, a positioning cylinder 47 is fixedly connected inside the groove 43, and a third magnetic block 61 is fixedly connected to the bottom of the sealing plate 6. The third magnetic block 61 is magnetically connected inside the positioning cylinder 47 to fix the sealing plate 6 in a simple way, which facilitates the later disassembly and replacement of the aromatherapy tablet 5. A finger groove 62 is provided on the top of the sealing plate 6, and a finger can be inserted into the finger groove 62 to facilitate the disassembly of the sealing plate 6.

[0041] In another specific embodiment of the present invention: as follows Figure 6 As shown, a positioning hole 51 is provided in the middle of the aromatherapy tablet 5. The aromatherapy tablet 5 is sleeved on the outer surface of the positioning cylinder 47 through the positioning hole 51, which can position the aromatherapy tablet 5 and prevent the aromatherapy tablet 5 from shaking back and forth in the groove 43, which would block the air outlet 45 on one side.

[0042] The working principle of this invention is as follows: In use, the air inlet pipe 1, U-shaped pipe 11, and air outlet box 2 are laid on the floor of the commercial vehicle. The air inlet pipe 1 is connected to the air conditioner of the commercial vehicle. The air outlet box 2 is installed under the two seats in the second row of the commercial vehicle. The U-shaped pipe 11 guides the gas to the air outlet box 2. When blowing cold or warm air, the motor 3 starts, causing the cover plate 41 to rise, so that the cold or warm air circulates from the bottom of the floor upwards. When not in use, the motor starts, causing the cover plate 41 to fall and close the air outlet box 2, which can prevent dust on the floor from entering the air outlet box 2. If the motor 3 is damaged in the future and needs to be repaired or replaced, the cover plate 41 is pulled upwards to overcome the repulsive force between the first magnetic block 25 and the second magnetic block 36. Then the cover plate 41 is rotated and pulled upwards again, so that the motor 3 can be disassembled for maintenance. The later maintenance is simple.
