Description

Technical Field

[0001] The utility model relates to the technical field of air curtains, and more specifically, to a vehicle-mounted air curtain. Background Art

[0002] An air curtain, also known as an air curtain machine, door curtain machine, air curtain machine, or air door, is mainly used to be installed at the entrances and exits of public places with an air-conditioned environment. By using a specially designed high-speed motor to drive a cross-flow, centrifugal, or axial-flow air wheel to rotate, a powerful air flow barrier is generated, forming an invisible curtain. It can effectively keep the indoor air clean, prevent the convection of hot and cold air, reduce air-conditioning energy consumption, extend the service life of the air conditioner, and prevent the intrusion of dust, insects, and harmful gases. Existing buses and coaches also have an air-conditioned environment, so a vehicle-mounted air curtain is needed.

[0003] However, there are various types of air curtain machines in the prior art. For example, the utility model patent CN211953173U relates to an air curtain machine. The utility model includes a housing with a receiving cavity, an air inlet is provided at the front end of the housing, and an air outlet is provided at the bottom end of the housing; an air wheel, the air wheel is arranged in the receiving cavity of the housing; a motor, the motor is arranged on the side wall of the housing, the motor is arranged inside the air wheel, and the output shaft of the motor is in transmission connection with the air wheel. In one embodiment of the utility model, the motor of an air curtain machine is arranged at the side end of the housing and inside the air wheel. When the air wheel rotates, it takes away the heat of the motor, solving the heat dissipation problem of the motor. The motor does not occupy additional receiving space, and the air outlet of the air curtain machine can cover the bottom end of the housing. The air curtain machine has uniform air output, and the motor does not affect the air output efficiency at the bottom end of the air curtain machine.

[0004] Although this air curtain machine can reduce the occupied space of the motor and has more uniform air output, it is installed at a high place. During daily maintenance, usually the entire air curtain machine needs to be disassembled, which is difficult to maintain and very inconvenient. For an air curtain machine with a detachable air inlet panel, it is also inconvenient to disassemble the air inlet panel without tools. To avoid this phenomenon, it is very necessary to design a vehicle-mounted air curtain. Summary of the Utility Model

Specific embodiments

[0028] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the following detailed description of the specific embodiments of the present utility model will be given in conjunction with the accompanying drawings of the specification.

[0029] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0030] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present utility model. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that excludes other embodiments. The present utility model provides the following embodiments.

[0031] Such as Figure 1 、 Figure 2 And Figure 4As shown in the figure, it is a schematic structural diagram of the vehicle air curtain in this embodiment. The air curtain in this embodiment includes an installation housing 1. A wind inlet hood 2 is provided on the front of the installation housing 1. Two installation cylinders 5 are fixed to the top and bottom of the wind inlet hood 2 respectively. A movable block 6 is slidably installed inside each installation cylinder 5. Clamping blocks 7 are provided on the surfaces of the two groups of movable blocks 6 close to each other. Slots 4 are provided at the top and bottom of the installation housing 1, and the slots 4 are matched with the clamping blocks 7. A return spring 8 is provided inside each installation cylinder 5, and one end of the return spring 8 is fixed to the movable block 6. The return spring 8 is in a compressed state. A rubber plug 9 is embedded at one end of each installation cylinder 5. A pulling rope 10 is fixed to the bottom of the rubber plug 9, and one end of the pulling rope 10 is fixed to the movable block 6. An adjusting head 11 is provided on the top of the rubber plug 9. During daily maintenance, when quickly disassembling the wind inlet hood 2 of the air curtain, only need to use the adjusting head 11 to pull out the rubber plug 9, and at the same time tighten the pulling rope 10. Drive the movable block 6 at one end to slide through the pulling rope 10, so that the movable block 6 drives the clamping block 7 to withdraw from the slot 4, release the fixing effect of the clamping block 7, and then the wind inlet hood 2 can be removed; when reassembling the maintained wind inlet hood 2 on the front of the installation housing 1 and closing the wind inlet hood 2, by using the resilience of the return spring 8, the clamping block 7 will slowly snap into the corresponding slot 4 along the trajectory of its inclined surface, and reposition the clamping block 7 through the slot 4 to complete the fixing of the wind inlet hood 2. Thus, it is not necessary to disassemble the entire air curtain machine, and it is convenient to disassemble the wind inlet hood 2 without tools, which is beneficial for daily maintenance and is relatively convenient.

[0032] It should be noted that the return spring 8, rubber plug 9, pulling rope 10 and adjusting head 11 in this embodiment form a limiting component, and the limiting component is used to limit the moving movable block 6 to facilitate fixing the wind inlet hood 2 on the entire air curtain machine.

[0033] As Figure 3 and Figure 5 shown, a number of air inlet holes 12 are provided through the wind inlet hood 2 in this embodiment. An air outlet 13 is provided at the bottom of the installation housing 1. A connecting wire 3 is provided through the installation housing 1, and the connecting wire 3 is located at the central position of the top of the installation housing 1. The multiple movable blocks 6 can be divided into a group at the top and a group at the bottom. During the operation of the air curtain, the side-inlet and bottom-outlet method is adopted, and the air is introduced into the air curtain through the air inlet holes 12, and then a high-speed air flow is generated, so as to blow out the high-speed air flow from the air outlet 13.

[0034] In addition, as Figure 6 、 Figure 7 and Figure 8As shown in the figure, in this embodiment, a first fixing bracket 14 and a second fixing bracket 19 are provided on the back of the installation housing 1, and the second fixing bracket 19 is fixed above the first fixing bracket 14. The first fixing bracket 14 is L-shaped, and the second fixing bracket 19 is Z-shaped. A plurality of fixing cross plates 18 are installed inside the first fixing bracket 14 through the third bolts 22. A plurality of installation support plates 15 are installed on one side of the second fixing bracket 19 through the first bolts 20. The top of the fixing cross plate 18 is fixedly connected to a fixing vertical plate 16, and the fixing vertical plate 16 and the installation support plate 15 are fixed to each other through the first bolt 20. Assembly plates 17 are fixedly connected to both side surfaces of the installation housing 1, and the assembly plates 17 and the fixing vertical plate 16 are fixed to each other through the second bolts 21. Since the existing conventional air curtains mostly adopt the wall-mounted installation method, but buses and coaches do not have enough wall surfaces for assembly. For this air curtain, first use the first bolt 20 to fix the second fixing bracket 19 of the installation housing 1 on the installation support plate 15, so that the whole air curtain is initially installed at the door of the coach or bus. At the same time, use the first bolt 20 to tighten the fixing vertical plate 16, so that the fixing cross plate 18 is docked with the first fixing bracket 14, and fasten it with the third bolt 22. Finally, tighten the assembly plate 17 and the fixing vertical plate 16 with the second bolt 21 to further fix the whole air curtain and ensure the stability of the air curtain after installation.

[0035] As Figure 5 shown in the figure, in this embodiment, two air impellers 25 are rotatably connected inside the installation housing 1 through bearings. The two air impellers 25 are symmetrically arranged. A bracket 23 is fixedly connected in the installation housing 1. The motor 24 is installed on the bracket 23. The output end of the motor 24 is fixed to one end of the air impeller 25. This air curtain is applied to the passenger door area of the bus. By generating high-speed air flow, it divides the indoor and outdoor into two independent temperature areas, maintains the effect of indoor air conditioning and purifies the air, and through forced air circulation, continuously forms an air door, which can effectively prevent the convection between the inside and outside of the vehicle compartment, achieving the purpose of saving energy and improving the environment.

[0036] It should be noted that in this embodiment, one end of the installation support plate 15 is fixed above the door inside the bus body 26, and nuts are threadedly connected to the surfaces of the first bolt 20, the second bolt 21, and the third bolt 22.

[0037] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirits of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
