Description

Technical Field

[0001] This application relates to the field of automotive air conditioning technology, and in particular to an automotive air conditioning system and vehicle that is compatible with both left- and right-hand drive vehicles. Background Technology

[0002] Due to differences in traffic rules across countries, the position of the steering wheel in cars also varies: some cars have the steering wheel on the left (left-hand drive) and some have the steering wheel on the right (right-hand drive). These are sometimes referred to as left-hand drive cars and right-hand drive cars. The different steering wheel positions often lead to certain changes in the car's structure.

[0003] With the development of the truck industry, the requirements for its internal air conditioning systems are becoming increasingly stringent. An air conditioning system, also known as HVAC, is a control system that includes temperature, humidity, air cleanliness, and air circulation. In recent years, there has been an increase in right-hand drive (right-hand drive) export vehicles, while my country is a left-hand drive (left-hand drive) country, which presents challenges for HVAC design.

[0004] In the existing technology, the HVAC assembly of traditional truck air conditioners is usually designed and arranged on the left and right sides below the dashboard, similar to the design of passenger car air conditioners. To meet the needs of the domestic market, it is necessary to design and develop a left-hand drive HVAC assembly, which requires the creation of a set of HVAC molds.

[0005] To accommodate right-hand drive vehicles due to the change in steering wheel position, it is often necessary to redesign and develop a HVAC assembly suitable for right-hand drive vehicles by mirroring the design of left-hand drive vehicles. This includes mirroring the design of the blower.

[0006] Such a layout design for the HVAC assembly involves a large workload and a long development cycle. In addition, a separate set of HVAC molds needs to be made specifically for right-hand drive models, which increases the investment in production molds and both design and mold costs, causing inconvenience to automobile manufacturing. Summary of the Invention

[0007] This application provides a car air conditioning system and vehicle that are compatible with both left and right drive vehicles, in order to solve the problem in the related art that air conditioning systems for right-hand drive vehicles require the redesign and development of HVAC assemblies suitable for right-hand drive vehicles through mirror design based on left-hand drive models, which leads to an increase in design and mold costs.

[0008] The first aspect of this application provides a car air conditioning system that is compatible with both left- and right-hand drive vehicles, including: An air conditioner housing, wherein the air conditioner housing is a hollow shell structure extending horizontally from left to right, and the air conditioner housing includes a front shell and a rear shell that are joined together to form an internal air duct. Both the front and rear housings are provided with a blower motor mounting point for installing a blower motor, a filter mounting point for installing an air inlet filter, an air conditioning pipe interface for installing an evaporator core, a coolant pipe interface for installing a heater core, and a damper motor mounting point for adapting to the damper mechanism.

[0009] In some embodiments, the system further includes an air conditioning functional component, which includes a blower, an evaporator core, a heater core, and a damper mechanism located within the air conditioning housing and arranged sequentially from the air inlet direction to the air outlet direction.

[0010] In some embodiments: when the automotive air conditioning system is used in a left-hand drive vehicle, an air intake filter is installed on the front housing via the filter mounting point; A blower motor is mounted on the rear end housing via the blower motor mounting point, and the blower motor is connected to the blower. A damper motor is mounted on the rear housing via the damper motor mounting point, and the damper motor is connected to the damper mechanism.

[0011] In some embodiments: when the automotive air conditioning system is used in a right-hand drive vehicle, an intake filter is installed on the rear housing via the filter mounting point; A blower motor is mounted on the front end housing via the blower motor mounting point, and the blower motor is connected to the blower. A damper motor is mounted on the front end housing via the damper motor mounting point, and the damper motor is connected to the damper mechanism.

[0012] In some embodiments: the air conditioning pipe interface for installing the evaporator core and the coolant pipe interface for installing the heater core on the front and rear housings are all knockout holes; When the automotive air conditioning system is used in a left-hand drive vehicle, the air conditioning pipe interface and coolant pipe interface on the front housing are opened so that the air conditioning pipe passes through the air conditioning pipe interface on the front housing and connects to the evaporator core, and the coolant pipe passes through the coolant pipe interface on the front housing and connects to the heater core.

[0013] In some embodiments: the air conditioning pipe interface for installing the evaporator core and the coolant pipe interface for installing the heater core are on the front and rear housings, and both the air conditioning pipe interface and the coolant pipe interface are knockout holes; When the automotive air conditioning system is used in a right-hand drive vehicle, the air conditioning pipe interface and coolant pipe interface on the rear housing are opened so that the air conditioning pipe passes through the air conditioning pipe interface on the rear housing and connects to the evaporator core, and the coolant pipe passes through the coolant pipe interface on the rear housing and connects to the heater core.

[0014] In some embodiments: air conditioning drain outlets are provided at the bottom of the front and rear housings respectively; annular sealing gaskets and / or sealant are provided on the mating surfaces of the front and rear housings; the front and rear housings are connected by bolts; and multiple instrument frame mounting points for connecting the instrument frame and cab front bulkhead fixing points are provided on both the front and rear housings.

[0015] In some embodiments, a sealing cover for sealing holes in the front bulkhead of the cab is also included, wherein the outer periphery of the air conditioning pipe interface and the coolant pipe interface on the front and rear housings are provided with sealing cover mounting points for detachably connecting the sealing cover. When the automotive air conditioning system is used in a left-hand drive vehicle, the sealing cover is connected to the front housing via the sealing cover mounting point; when the automotive air conditioning system is used in a right-hand drive vehicle, the sealing cover is connected to the rear housing via the sealing cover mounting point.

[0016] In some embodiments, the front end housing and the rear end housing are respectively provided with mounting brackets for detachably installing the evaporator core and the heater core, and the evaporator core and the heater core can be fixed on the mounting brackets by rotating 180° around the Z-axis.

[0017] A second aspect of this application provides a vehicle, including: The driver's cab is equipped with a left- or right-hand drive universal automotive air conditioning system as described in any of the above embodiments. The length of the automotive air conditioning system extends along the width of the driver's cab, and the air conditioning unit housing of the automotive air conditioning system is connected to the front bulkhead of the driver's cab and the instrument frame.

[0018] The beneficial effects of the technical solution provided in this application include: This application provides an auto air conditioning system and vehicle that are compatible with both left and right-hand drive vehicles. The auto air conditioning system of this application is equipped with an air conditioning housing, which is a hollow shell structure that extends horizontally from left to right. The air conditioning housing includes a front shell and a rear shell that are joined together to form an internal air duct. The front shell and the rear shell are respectively provided with a blower motor mounting point for installing a blower motor, a filter mounting point for installing an air intake filter, an air conditioning pipe interface for installing an evaporator core, a coolant pipe interface for installing a heater core, and a damper motor mounting point for adapting to the damper mechanism.

[0019] Therefore, the left- or right-hand drive universal automotive air conditioning system of this application sets the air conditioning housing as a hollow shell structure extending horizontally from left to right. This structure makes the horizontal dimension of the air conditioning housing large and the vertical dimension small, thus making full use of the space under the dashboard. The dimension of this space in the left-right direction is definitely larger than the dimension in the vertical direction, making it easier to arrange the air conditioning housing under the dashboard. The air conditioning housing includes a front shell and a rear shell that fit together to form the internal air duct. Both the front shell and the rear shell are provided with a blower motor mounting point, a filter mounting point, an air conditioning pipe interface, a coolant pipe interface, and a damper motor mounting point.

[0020] When transferring the car's air conditioning system from a left-hand drive vehicle to a right-hand drive vehicle, the entire air conditioning unit housing is rotated 180° around the vehicle's Z-axis. This rotation results in the following changes: the air vents remain in the center; the blower is moved from the left to the right; and the mounting points for the blower motor, filter, air conditioning lines, coolant lines, and damper motor, originally located on the front housing, are moved to the rear, while the same mounting points are moved to the front. Because both the front and rear housings have mounting points for the blower motor, filter, air conditioning lines, coolant lines, and damper motor, it can be used in right-hand drive vehicles, achieving a universal air conditioning unit housing for both left-hand and right-hand drive vehicles, thus reducing mold and production costs.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] This application provides a universal automotive air conditioning system and vehicle for both left and right drive vehicles. It solves the problem that air conditioning systems for right-hand drive vehicles require redesigning and developing HVAC assemblies suitable for right-hand drive vehicles by mirroring the design of left-hand drive models, which increases design and mold costs.

[0026] See Figures 1 to 4 As shown, the first aspect of this application provides a car air conditioning system that is compatible with both left- and right-hand drive vehicles, including: The air conditioner housing 10 is a hollow shell structure extending horizontally from left to right. The air conditioner housing 10 includes a front outer shell 11 and a rear outer shell 12 that fit together to form an internal air duct. Both the front outer shell 11 and the rear outer shell 12 are integrally injection molded. The left-right direction of the air conditioner housing 10 is... Figure 1 In the X-axis direction, the front-to-back direction of the air conditioner housing 10 is... Figure 1 In the Y-axis direction, the vertical direction of the air conditioner housing 10 is... Figure 1 The Z-axis direction in the equation.

[0027] Both the front housing 11 and the rear housing 12 are provided with a blower motor mounting point 22 for mounting the blower motor 18, a filter mounting point 21 for mounting the air inlet filter 17, an air conditioning pipe interface 23 for mounting the evaporator core 14, a coolant pipe interface 24 for mounting the heater core 15, and a damper motor mounting point 25 for adapting the damper mechanism 16. That is, the front housing 11 and the rear housing 12 have mounting points for the same air conditioning functional devices.

[0028] The automotive air conditioning system of this application embodiment, which is applicable to both left and right-hand drive vehicles, sets the air conditioning housing 10 as a hollow shell structure that extends horizontally from left to right. This structure makes the horizontal dimension (X-axis direction) of the air conditioning housing 10 large and the vertical dimension (Z-axis direction) small, thereby making full use of the space under the dashboard. This space has the characteristic that the dimension in the left-right direction is always greater than the dimension in the vertical direction, making it easier to arrange the air conditioning housing 10 under the dashboard.

[0029] The air conditioner housing 10 includes a front housing 11 and a rear housing 12 that are joined together to form an internal air duct. Both the front housing 11 and the rear housing 12 are provided with a blower motor mounting point 22, a filter mounting point 21, an air conditioning pipe interface 23, a coolant pipe interface 24, and a damper motor mounting point 25, so that the air conditioner housing 10 can be directly used for the air conditioning system of a right-hand drive vehicle after rotating 180° around the Z-axis.

[0030] When the car's air conditioning system is transferred from a left-hand drive vehicle to a right-hand drive vehicle, the entire air conditioning unit housing 10 is rotated 180° around the vehicle's Z-axis. This rotation results in the following changes: the air outlet of the air conditioning unit housing 10 remains in the center; the blower 13 is moved from the left to the right; the blower motor mounting point 22, filter mounting point 21, air conditioning pipe interface 23, coolant pipe interface 24, and damper motor mounting point 25, originally located on the front housing 11, are moved to the rear; and the blower motor mounting point 22, filter mounting point 21, air conditioning pipe interface 23, coolant pipe interface 24, and damper motor mounting point 25, originally located on the rear housing 12, are moved to the front.

[0031] Since both the front housing 11 and the rear housing 12 are equipped with a blower motor mounting point 22, a filter mounting point 21, an air conditioning pipe interface 23, a coolant pipe interface 24, and a damper motor mounting point 25, they can meet the needs of left-hand drive vehicles. By rotating them 180° around the Z-axis of the vehicle, they can also meet the needs of right-hand drive vehicles. This achieves the universality of the air conditioning housing 10 for both left-hand drive and right-hand drive vehicles, reducing mold costs and production costs.

[0032] In some alternative embodiments: see Figures 1 to 4 As shown, this application embodiment provides a car air conditioning system that is compatible with both left and right-hand drive vehicles. The car air conditioning system also includes an air conditioning functional component, which includes a blower 13, an evaporator core 14, a heater core 15, and a damper mechanism 16 arranged sequentially from the air intake direction to the air outlet direction within the air conditioning housing 10, thereby realizing the basic functions of the car air conditioning system such as air intake, air exhaust, cooling, heating, and air volume regulation.

[0033] When the automotive air conditioning system is used in a left-hand drive vehicle, an intake air filter 17 is installed on the front housing 11 via filter mounting point 21. A blower motor 18 is installed on the rear housing 12 via blower motor mounting point 22, and the blower motor 18 is connected to the blower 13 to drive its rotation for air intake. A damper motor 19 is installed on the rear housing 12 via damper motor mounting point 25, and the damper motor 19 is connected to the damper mechanism 16 to adjust the rotation angle of the damper mechanism 16.

[0034] When the automotive air conditioning system is used in a right-hand drive vehicle, an intake air filter 17 is installed on the rear housing 12 via filter mounting point 21 (the intake air filter 17 is swapped from the front housing 11 to the rear housing 12). A blower motor 18 is installed on the front housing 11 via blower motor mounting point 22 (the blower motor 18 is swapped from the rear housing 12 to the front housing 11), and the blower motor 18 is connected to the blower 13 to drive its rotation for air intake. A damper motor 19 is installed on the front housing 11 via damper motor mounting point 25 (the damper motor 19 is swapped from the rear housing 12 to the front housing 11), and the damper motor 19 is connected to the damper mechanism 16 to adjust the rotation angle of the damper mechanism 16.

[0035] In this embodiment, a blower 13, an evaporator core 14, a heater core 15, and a damper mechanism 16 are arranged sequentially from the air intake direction to the air outlet direction within the air conditioner housing 10, realizing the functions of air intake, air exhaust, cooling, heating, and airflow regulation of the automotive air conditioning system. Depending on whether the automotive air conditioning system is used in a left-hand drive or right-hand drive vehicle, the air intake filter 17, blower motor 18, and damper motor 19 are respectively installed on the front housing 11 and rear housing 12 using the blower motor mounting point 22, filter mounting point 21, air conditioning pipe interface 23, coolant pipe interface 24, and damper motor mounting point 25.

[0036] In some alternative embodiments: see Figures 1 to 4 As shown, this application embodiment provides a car air conditioning system that is compatible with both left- and right-hand drive vehicles. The front housing 11 and rear housing 12 of this car air conditioning system have air conditioning pipe interfaces 23 for installing the evaporator core 14, and coolant pipe interfaces 24 for installing the heater core 15. Both the air conditioning pipe interfaces 23 and the coolant pipe interfaces 24 are knockout holes. When the air conditioning pipe interface 23 needs to install the evaporator core 14, and the coolant pipe interface 24 needs to install the heater core 15, the knockout holes can be gently tapped with a hammer, screwdriver, or pliers to remove the components, forming a complete through hole.

[0037] When the car air conditioning system is used in a left-hand drive vehicle, the air conditioning pipe interface 23 and the coolant pipe interface 24 on the front housing 11 are opened so that the air conditioning pipe passes through the air conditioning pipe interface 23 on the front housing 11 and connects to the evaporator core 14, and the coolant pipe passes through the coolant pipe interface 24 on the front housing 11 and connects to the heater core 15.

[0038] The evaporator core 14 needs to be connected to the compressor and condenser located outside the cab via the air conditioning pipes. The heater core 15 needs to be connected to the engine located outside the cab via the coolant pipes. The air conditioning pipes and coolant pipes located outside the cab need to pass through the cab front bulkhead and connect to the evaporator core 14 and the heater core 15. The front end shell 11 is close to the cab front bulkhead, so the air conditioning pipe interface 23 and the coolant pipe interface 24 on the front end shell 11 need to be opened before the evaporator core 14 and the heater core 15 can be connected to the air conditioning pipes and the coolant pipes respectively.

[0039] In some alternative embodiments: see Figures 1 to 4 As shown, this application embodiment provides a car air conditioning system that is compatible with both left- and right-hand drive vehicles. The front housing 11 and rear housing 12 of this car air conditioning system have air conditioning pipe interfaces 23 for installing the evaporator core 14, and coolant pipe interfaces 24 for installing the heater core 15. Both the air conditioning pipe interfaces 23 and the coolant pipe interfaces 24 are knockout holes. When the air conditioning pipe interface 23 needs to install the evaporator core 14, and the coolant pipe interface 24 needs to install the heater core 15, the knockout holes can be gently tapped with a hammer, screwdriver, or pliers to remove the components, forming a complete through hole.

[0040] When the car air conditioning system is used in a right-hand drive vehicle, first rotate the air conditioning housing 10 180° around the Z-axis of the vehicle, and change the rear housing 12 from the rear to the front. Open the air conditioning pipe interface 23 and coolant pipe interface 24 on the rear housing 12 so that the air conditioning pipe passes through the air conditioning pipe interface 23 on the rear housing 12 and connects to the evaporator core 14, and the coolant pipe passes through the coolant pipe interface 24 on the rear housing 12 and connects to the heater core 15.

[0041] The evaporator core 14 needs to be connected to the compressor, condenser, etc. located outside the cab via the air conditioning pipe. The heater core 15 needs to be connected to the engine located outside the cab via the coolant pipe. The air conditioning pipe and coolant pipe located outside the cab need to pass through the front bulkhead of the cab and connect to the evaporator core 14 and the heater core 15. At this time, the rear shell 12 is close to the front bulkhead of the cab. Therefore, the air conditioning pipe interface 23 and the coolant pipe interface 24 on the rear shell 12 need to be opened before the evaporator core 14 and the heater core 15 can be connected to the air conditioning pipe and the coolant pipe respectively.

[0042] In some alternative embodiments: see Figures 1 to 4 As shown in the figure, this application provides a car air conditioning system that is compatible with both left and right-hand drive vehicles. The bottom of the front housing 11 and the rear housing 12 of the car air conditioning system are respectively provided with air conditioning drain outlets 28. The mating surfaces of the front housing 11 and the rear housing 12 are provided with annular sealing gaskets and / or sealant to prevent air conditioning condensate from leaking from the mating surfaces of the front housing 11 and the rear housing 12.

[0043] The front housing 11 and the rear housing 12 are connected by bolts. After the front housing 11 and the rear housing 12 are opened by bolts, the blower 13, evaporator core 14, heater core 15 and damper mechanism 16 can be installed inside the air conditioner housing 10. Both the front housing 11 and the rear housing 12 are provided with multiple instrument frame mounting points 27 for connecting the instrument frame, and cab front bulkhead fixing points 26 for connecting the cab front bulkhead.

[0044] The instrument frame mounting point 27 and the cab front panel fixing point 26, which are respectively provided on the front housing 11 and the rear housing 12, can be connected to the instrument frame and the cab front panel. The air conditioner housing 10 can be fixed inside the instrument panel of the cab, whether it is used for left-hand drive or right-hand drive vehicles.

[0045] In some alternative embodiments: see Figures 1 to 4 As shown, this application embodiment provides a car air conditioning system that is compatible with both left and right-hand drive vehicles. The system also includes a sealing cover 29 for sealing holes in the front bulkhead of the driver's cab. The air conditioning pipe interface 23 and coolant pipe interface 24 on the front housing 11 and rear housing 12 are each provided with a sealing cover mounting point for detachable connection to the sealing cover 29. The end of the sealing cover 29 away from the front housing 11 or rear housing 12 is provided with sealing foam that conforms to the front bulkhead of the driver's cab.

[0046] When the automotive air conditioning system is used in a left-hand drive vehicle, the sealing cover 29 is connected to the front housing 11 via the sealing cover mounting point. When the automotive air conditioning system is used in a right-hand drive vehicle, the sealing cover 29 is connected to the rear housing 12 via the sealing cover mounting point. The sealing cover 29 is used to seal the holes in the front bulkhead of the cab, thereby isolating the cab from the outside environment and preventing air, water, dust, etc. from outside the cab from entering the cab through the holes in the front bulkhead of the cab.

[0047] The front housing 11 and rear housing 12 are respectively equipped with mounting brackets for detachable installation of the evaporator core 14 and the heater core 15. Both the evaporator core 14 and the heater core 15 can be mounted and fixed on the mounting brackets by rotating 180° around the Z-axis. The evaporator core 14 and the heater core 15 can be oriented according to whether the automotive air conditioning system is used in a left-hand drive or right-hand drive vehicle. Regardless of the orientation of the front housing 11 and the rear housing 12, after the evaporator core 14 and the heater core 15 are adjusted, their pipe joints always face the front bulkhead of the cab.

[0048] See Figures 1 to 4 As shown, a second aspect of this application provides a vehicle, including: The driver's cab is equipped with a left- or right-hand drive universal automotive air conditioning system as described in any of the above embodiments. The length of the automotive air conditioning system extends along the width of the driver's cab, and the air conditioning unit housing 10 of the automotive air conditioning system is connected to the front bulkhead of the driver's cab and the instrument frame.

[0049] Working principle This application provides an auto air conditioning system and vehicle that is compatible with both left and right drive. The auto air conditioning system of this application is equipped with an air conditioning housing 10, which is a hollow shell structure that extends horizontally from left to right. The air conditioning housing 10 includes a front shell 11 and a rear shell 12 that are joined together to form an internal air duct. The front shell 11 and the rear shell 12 are respectively provided with a blower motor mounting point 22 for installing a blower motor 18, a filter mounting point 21 for installing an air intake filter 17, an air conditioning pipe interface 23 for installing an evaporator core 14, a coolant pipe interface 24 for installing a heater core 15, and a damper motor mounting point 25 for adapting to the damper mechanism 16.

[0050] Therefore, the left-hand drive and right-hand drive universal automotive air conditioning system of this application sets the air conditioning housing 10 as a hollow shell structure that extends horizontally from left to right. This structure makes the horizontal dimension of the air conditioning housing 10 large and the vertical dimension small, thus making full use of the space under the dashboard. The horizontal dimension is always larger than the vertical dimension, making it easier to arrange the air conditioning housing 10 under the dashboard. The air conditioning housing 10 includes a front shell 11 and a rear shell 12 that are joined together to form an internal air duct. Both the front shell 11 and the rear shell 12 are provided with a blower motor mounting point 22, a filter mounting point 21, an air conditioning pipe interface 23, a coolant pipe interface 24, and a damper motor mounting point 25.

[0051] When the air conditioning system is transferred from a left-hand drive vehicle to a right-hand drive vehicle, the entire air conditioning unit housing 10 is rotated 180° around the Z-axis of the vehicle. This rotation results in the following changes: the air outlet of the air conditioning unit housing 10 remains in the center; the blower 13 is moved from the left to the right; the blower motor mounting point 22, filter mounting point 21, air conditioning pipe interface 23, coolant pipe interface 24, and damper motor mounting point 25, originally located on the front housing 11, are moved to the rear; and the same mounting points are moved from the rear housing 12 to the front. Since both the front and rear housings 11 and 12 have these mounting points, it can be used in right-hand drive vehicles, achieving universality for the air conditioning unit housing 10 in both left-hand and right-hand drive vehicles, thus reducing mold and production costs.
