Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle air equipment, and particularly relates to an air conditioning unit cover plate fixing protection structure and an air conditioning unit. Background Art

[0002] Air conditioning units are installed on large passenger cars, subways, EMUs, high-speed trains and other vehicles. Most air conditioning units are unit structures and are installed as a whole on the roof of the carriage. Due to the special operating environment of the vehicle and the large vibration during the operation of the vehicle, the cover of the air conditioning unit needs to be firmly fixed. At present, the cover of the air conditioning unit is generally fixed by bolts or tension locks.

[0003] In actual operation, there are situations where bolts are forgotten to be installed, the tension lock is forgotten to be tightened, or the tension lock is not locked tightly. If the vehicle runs at high speed under this circumstance, the cover may fly up and cause a major accident. Therefore, the cover of the air-conditioning unit needs to adopt a secondary protection structure.

[0004] At present, the commonly used secondary protection forms of cover plates for air-conditioning units include bird hooks, latches, bolt pressure plates, etc. Among them, for the secondary protection structure using bolt pressure plates, tools such as sleeves and screwdrivers are required during operation, which is troublesome to operate, and the bolt pressure plates are loose parts after being removed, which is very easy to lose. Utility Model Content

[0005] The main technical problem solved by the utility model is to provide an air-conditioning unit cover fixing and protecting structure which is simple and convenient to operate and will not cause the loss of dismantled bolts and other loose parts, and at the same time provide an air-conditioning unit using the cover fixing and protecting structure.

[0006] In order to solve the above technical problems, the first technical solution adopted by the utility model is:

[0007] A protective structure for fixing a cover plate of an air-conditioning unit comprises a base and a pressure plate, wherein the base is fixed on an outer shell of the air-conditioning unit, and the pressure plate presses the cover plate onto the outer shell from the outer side of the cover plate of the air-conditioning unit, and the base and the pressure plate are connected by an elastic connection component, and the elastic connection component is configured to enable the pressure plate to perform linear movement and rotation relative to the base to realize conversion between a locked position and an open position.

[0008] Furthermore, the elastic connection assembly consists of a connecting shaft and an elastic member mounted on the connecting shaft. One end of the connecting shaft passes upward through the base and is fixedly connected to the pressure plate. The connecting shaft can move linearly and rotate relative to the base. A limit plate is provided at the other end of the connecting shaft, and the elastic member is installed between the limit plate and the base.

[0009] Furthermore, the elastic member is a spring.

[0010] Furthermore, the elastic member has an initial elastic force to tightly press the pressing plate against the outer side of the cover plate.

[0011] Furthermore, the pressure plate is an inverted "X" or Z-shaped structure, consisting of a wing plate extending to one side or both sides, a first mounting plate and a first connecting plate connecting the wing plate and the first mounting plate. The wing plate is parallel to the first mounting plate, and the wing plate is pressed tightly against the outer side of the cover plate. The end of the connecting shaft is fixedly connected to the first mounting plate in the middle.

[0012] Furthermore, a handle is fixedly installed on a surface of the pressing plate facing away from the base.

[0013] Furthermore, the handle is in an inverted U shape, with both ends fixed on the pressure plate, and the axis of the connecting shaft coincides with the center line of the handle.

[0014] Furthermore, a receiving space is provided on the base, and the connecting shaft and the elastic member are installed in the receiving space.

[0015] Furthermore, the base is in the shape of a Chinese numeral 5, and is composed of fixed plates on left and right sides, a second mounting plate in the middle, and two second connecting plates connecting the fixed plate and the second mounting plate. Mounting holes are respectively provided on the fixed plates on both sides, which are fixedly connected to the outer shell by fasteners, and a through hole is provided on the second mounting plate for passing the connecting shaft.

[0016] In order to solve the above technical problems, the second technical solution adopted by the utility model is:

[0017] An air conditioning unit comprises an outer shell and a cover plate, between which the above-mentioned air conditioning unit cover plate fixing and protective structure is fixedly installed.

[0018] In summary, the air-conditioning unit cover plate fixing protection structure and the air-conditioning unit provided by the utility model have the following advantages compared with the prior art:

[0019] (1) The utility model connects the base and the pressure plate through an elastic connection component, which can realize linear movement and rotation of the pressure plate relative to the base, so that the pressure plate is pressed against the cover plate when in the locked position, thereby playing a secondary protection role. At the same time, the pressure plate can also be rotated to the open position to release the pressure plate, and the cover plate can be opened freely. Not only is the overall structure simple, but the operation is also very convenient, and there is no need to use tools such as sockets and screwdrivers in the prior art.

[0020] (2) The base and the pressure plate of the utility model are connected by an elastic connection component, and the elastic force of the elastic connection component can be used to firmly lock the pressure plate in a locked position, which can effectively prevent the failure of the protective structure during the operation of the vehicle, thereby ensuring driving safety.

[0021] (3) When the cover plate needs to be locked or opened, the utility model does not need to disassemble the pressure plate and the elastic connection assembly, that is, the pressure plate can be switched between the locked position and the open position without the problem of loss of disassembled parts.

[0037] Embodiment 1:

[0038] like Figures 1 to 6 As shown, the utility model provides an air-conditioning unit cover plate fixing protection structure, which is used for secondary protection between the air-conditioning unit casing 1 and the cover plate 2. The cover plate 2 can be flipped and connected to the casing 1 to open or close the casing 1. The cover plate 2 is mainly fixedly connected to the casing 1 by additional bolts or tension locks (not shown in the figure).

[0039] In this embodiment, the cover fixing protection structure of the air-conditioning unit includes a base 3 and a pressure plate 4. The base 3 is fixed on the outer shell 1 of the air-conditioning unit. The pressure plate 4 presses the cover 2 on the outer shell 1 from the outside of the cover 2. The pressure plate 4 serves as an auxiliary protection structure. It can be used to prevent the cover 2 from opening during the operation of the vehicle in the event of forgetting to install the bolts, forgetting to tighten the tension lock, or the tension lock is not locked tightly. It plays a secondary protection role for the cover 2 and ensures the safe operation of the vehicle.

[0040] In this embodiment, the base 3 and the pressure plate 4 are connected by an elastic connection component 5, and the elastic connection component 5 is configured to enable the pressure plate 4 to move linearly and rotate relative to the base 3, so that the pressure plate 4 can be switched between the locked position and the unlocked position.

[0041] In this embodiment, the base 3 and the pressing plate 4 are connected by an elastic connection component 5, which can realize linear movement and rotation of the pressing plate 4 relative to the base 3, so that the pressing plate 4 is pressed against the cover plate 2 when in the locked position, and can also be rotated to the open position by rotating the pressing plate 4. At this time, the pressing plate 4 and the cover plate 2 are parallel, and the pressing plate 4 releases the cover plate 2, and there is no longer a pressing relationship between the cover plate 2, and the cover plate 2 can be opened freely. This structure is not only easy to operate, without the need to use tools such as sleeves and screwdrivers in the prior art, but also without the need to disassemble the pressing plate 4 and the elastic connection component 5, that is, the pressing plate 4 can be switched between the locked position and the open position, and the problem of loss of disassembled parts will not occur.

[0042] In this embodiment, preferably, the elastic connection assembly 5 includes a connection shaft 51 and an elastic member 52 mounted on the connection shaft 51, and a through hole (not shown in the figure) is provided on the base 3, one end of the connection shaft 51 (the top end of the connection shaft 51 in the figure) passes upward through the through hole on the base 3 and is fixedly connected to the upper pressing plate 4, the pressing plate 4 moves synchronously with the connection shaft 51, and the connection shaft 51 and the through hole are clearance-matched, so that the connection shaft 51 can move linearly and rotate relative to the base 3. In this embodiment, the linear movement is a linear direction toward or away from the base 3, a limit plate 53 is provided at the other end of the connection shaft 51, and the elastic member 52 is installed between the limit plate 53 and the base 3.

[0043] In this embodiment, the elastic member 52 is preferably a spring 521, and the upper and lower ends of the spring 521 are respectively against the lower surface of the base 3 and the limit plate 53. When the cover 2 needs to be opened, the operator can lift the pressing plate 4 upward, at which time the spring 521 is compressed, and then rotate the pressing plate 4 to switch the pressing plate 4 to the open position. When rotating back to the locked position, release the pressing plate 4, and under the elastic force of the spring 521, the pressing plate 4 will automatically move toward the cover 2 and press on the outer side of the cover 2.

[0044] In the present embodiment, it is further preferred that the spring 521 has an initial elastic force, so that the pressure plate 4 can be tightly pressed against the outer side of the cover plate 2 when in the locked state, and the pressure plate 4 is firmly locked in the locked position to ensure that the cover plate 2 will not open and will not slip, thereby effectively avoiding failure of the protective structure during the operation of the vehicle and thereby ensuring driving safety.

[0045] In this embodiment, preferably, the pressing plate 4 is in the shape of an inverted "X", and is composed of wing plates 41 on the left and right sides, a first mounting plate 42 in the middle, and two first connecting plates 43 connecting the wing plates 41 and the first mounting plate 42. The wing plates 41 on both sides are arranged in parallel with the first mounting plate 42 in the middle, and the first connecting plates 43 on both sides are perpendicular to the wing plates 41 and the first mounting plate 42, and can also be arranged at an angle. When in the locked position, the wing plates 41 on both sides are used to press the outer side of the cover plate 2, and the top end of the connecting shaft 51 is fixedly connected to the first mounting plate 42 in the middle. The wing plates 41 on both sides can be used to press the two cover plates 2 at the same time. Of course, the structure with two wing plates 41 can also be used to press only one cover plate 2 on one side.

[0046] As for the pressing plate 4, another implementation is provided in this embodiment, in which the pressing plate 4 is a Z-shaped structure, has only one wing plate 41, and also includes a first mounting plate 42 and a first connecting plate 43 connecting the first mounting plate 42 and the wing plate 41. The wing plate 41 on one side is used to press the cover plate 2 on only one side.

[0047] The pressing plate 4 can be made of a metal material with good corrosion resistance and strength, such as stainless steel. In order to avoid damaging the surface of the cover plate 2, a protective gasket is attached to the lower surface of the wing plates 41 on the left and right sides of the pressing plate 4. The pressing plate 4 can also be made directly of nylon material.

[0048] In this embodiment, it is further preferred that a handle 6 is fixedly installed on the side of the pressing plate 4 facing away from the base 3, so that the operator can lift the pressing plate 4 upward. The pressing plate 4 is in an inverted "X" shape or a Z-shaped structure, and the space on one side of the first connecting plate 43 can be used as a space for installing the handle 6, so that the handle 6 will not protrude upward from the cover plate 2 for installation, thereby reducing the occupied space and protecting the handle 6 at the same time.

[0049] In this embodiment, the handle 6 further preferably adopts an inverted U-shaped structure, and the bottom ends at both ends are fixed on the first mounting plate 42 of the pressure plate 4, and the axis of the connecting shaft 51 coincides with the center line of the handle 6, ensuring that when the pressure plate 4 is lifted upward, the pressure plate 4 and the connecting shaft 51 will not deflect, and there will be no large friction between the connecting shaft 51 and the base 3, making the lifting action smoother.

[0050] In this embodiment, there is a accommodating space 31 on the base 3, and the connecting shaft 51 and the elastic member 52 are installed in the accommodating space 31. The height of the accommodating space 31 provides sufficient travel space for lifting the pressing plate 4, and the top end of the connecting shaft 51 passes upward through the base 3 and is fixedly connected to the pressing plate 4.

[0051] In this embodiment, the base 3 further preferably adopts a "J"-shaped structure, which is exactly opposite to the bending direction of the pressure plate 4, and is composed of fixed plates 32 on the left and right sides, a second mounting plate 33 in the middle, and two second connecting plates 34 connecting the fixed plate 32 and the second mounting plate 33. The second mounting plate 33 is arranged opposite to the first mounting plate 42 on the pressure plate 4. Mounting holes 321 are respectively arranged on the fixed plates 32 on both sides, which are fixedly connected to the housing 1 by bolts, and a through hole is provided on the second mounting plate 33 for passing the connecting shaft 51 in the elastic connecting component 5. The two second connecting plates 34 and the second mounting plate 33 are used to enclose the accommodating space 31. When installed, the seat 3 is parallel to the edge of the cover plate 2.

[0052] like Figures 4 to 6 As shown, the steps of opening the cover 2 are described in detail below:

[0053] 1. Loosen the bolts or tension locks used to secure the cover plate 2.

[0054] 2. The operator holds the handle 6 and lifts the pressing plate 4 upwards, at which time the spring 521 is compressed.

[0055] 3. Continue to rotate the pressing plate 4 by 90°, so that the pressing plate 4 and the cover plate 2 are in parallel, and the cover plate 2 is released.

[0056] 4. The air conditioner cover 2 can be opened at this time.

[0057] The following describes in detail the steps required to close the cover 2:

[0058] 1. After the cover plate 2 is buckled, tighten the fixing bolts or lock the tension lock.

[0059] 2. The operator holds the handle 6 and lifts the pressing plate 4 upwards, at which time the spring 521 is compressed.

[0060] 3. Continue to rotate the pressing plate 4 by 90°, so that the edges of the pressing plate 4 and the cover plate 2 are in a vertical position, and the wing plates 41 on the left and right sides of the pressing plate 4 are located above the cover plate 2. After releasing the pressing plate 4, the pressing plate 4 will move toward the cover plate 2 under the elastic force of the spring 521, and the wing plates 41 on the left and right sides will be pressed against the cover plate 2, and the secondary protection structure will take effect.

[0061] The air conditioning unit cover plate fixing protection structure provided by the utility model has the following advantages:

[0062] 1. The utility model connects the base and the pressure plate through an elastic connecting component, which can realize linear movement and rotation of the pressure plate relative to the base, so that the pressure plate is pressed against the cover plate when in the locked position, which plays a role of secondary protection.
