Description

[0001] This application is a divisional application of a patent application with an application date of September 25, 2018, application number 201811113415.4, and title “Vehicle Air Conditioning Device”. Technical Field

[0002] The present invention relates to a vehicle air conditioner, and more particularly to a vehicle air conditioner equipped with a cable pulley assembly as a driving unit for rotating a valve in an air conditioner casing. Background Art

[0003] Generally, a vehicle air conditioning device is a device for cooling or heating the interior of a vehicle by heating or cooling the air outside the vehicle while introducing the air into the vehicle interior or circulating the air inside the vehicle interior. An evaporator for performing a cooling effect, a heater core for performing a heating effect, and a blowing mode switching valve are provided inside the air conditioning housing. The blowing mode switching valve selectively blows the air cooled or heated by means of the evaporator or the heater core to various parts of the vehicle interior.

[0004] Figure 1 FIG is a cross-sectional view showing a conventional vehicle air conditioning device. Figure 1 As shown, a conventional vehicle air conditioner 1 includes an air conditioner housing 10 , a blower (not shown), an evaporator 2 , a heater core 3 , and a temperature adjustment valve 15 .

[0005] An air inlet 11 is formed on the inlet side of the air conditioner casing 10, and a defrost vent 12a, a face vent 12b, and a floor vent 12c are formed on the outlet side, each of which has its opening adjusted by a mode valve 16. A blower is connected to the air inlet 11 of the air conditioner casing 10 to blow indoor or outdoor air.

[0006] The evaporator 2 and the heater core 3 are sequentially arranged inside the air conditioner housing 10. The temperature adjustment valve 15 is arranged between the evaporator 2 and the heater core 3 to adjust the opening of the cold air flow path bypassing the heater core 3 and the hot air flow path passing through the heater core 3.

[0007] The mode valves 16 include a defrost valve that adjusts the opening of the defrost vents 12a, a face valve that adjusts the opening of the face vents 12b, and a floor valve that adjusts the opening of the floor vents 12c. The temperature adjustment valve 15 and the mode valve 16 are connected to an actuator located outside the air conditioner casing 10 and rotate to adjust the opening of the cold air flow path, the hot air flow path, or the opening of the flow path to each vent 12a to 12c.

[0008] Korean Patent Publication No. 10-1467263 (November 25, 2014), previously filed, discloses a cable connection device for a controller for a vehicle air conditioner. Figure 2 This is a side view of an air conditioner casing showing a state in which a conventional cable connection device is installed.

[0009] Reference Figure 2 The temperature adjustment valve 15 and the mode valve 16 are adjusted in opening and closing angle by the arm 28, the rod 25 and the cam 21 provided on the outer side of the air conditioner casing 10. The arm 28, the rod 25 and the cam 21 can control not only the mode valve 16 but also the temperature adjustment valve 15.

[0010] The cam 21 is rotatably coupled to the outer side of the air conditioner housing 10 and has a slot formed therein. An arm 28 is provided on the outer side of the air conditioner housing 10 and is directly connected to the rotation axis of each valve, rotating with the mode valve 16. A lever 25 is positioned between the cam 21 and the arm 28 and is rotatably coupled to the outer side of the air conditioner housing 10. One end of the lever 25 is slidably coupled to the slot 22 via a pin 142, while the other end is rotatably coupled to the arm 28, thereby transmitting the rotational force received from the cam 21 to the arm 28.

[0011] To control the air conditioning system, a controller is installed on the vehicle's center console. The controller consists of a switch mounted on a housing. A cable connection device 50 is installed on the rear side of the housing to move a cable 53 when the knob is turned. Furthermore, the cable connection device 50 connects the vehicle controller's motion mechanism to the motion mechanism on the air conditioning housing 10 via the cable 53, whose outer circumference is surrounded by a tube 31, to move the mode valve 16 inside the housing 10.

[0012] A pulley housing is formed inside the cable connection device 50 to allow a pulley 52 to be rotatably inserted therein. A casing 51 is provided on one side of the cable connection device 50 to allow one end of a cable 53 to be inserted into the pulley housing. A stopper protrusion is elastically provided on the inside of the casing 51 by an elastic member. A stopper protrudes from one side of the pulley 52 and has a plurality of stopper grooves 54 circumferentially along its outer circumference, so that the stopper protrusion is elastically engaged.

[0013] Thus, when a manual air conditioner using the above-mentioned cable must be shipped together with the controller for reasons such as delivery, there is a problem of damage or loss of the cable connection device 50. Furthermore, the additional structure added to protect the cable connection device 50 during delivery has the disadvantage of increasing transportation costs.

[0014] Furthermore, for manual air conditioners, the cable connection device 50 is attached to the exterior of the air conditioner housing 10 during the final assembly phase of the package before delivery. Since the cable connection device 50 is attached to the vehicle during assembly, it should be easily detachable from the air conditioner housing 10 on the vehicle assembly line. Existing cable connection devices 50 have weak fastening properties, resulting in potential detachment during assembly and transportation, or damage from external impact.

[0057] Hereinafter, the technical configuration of the vehicle air conditioning system will be described in detail with reference to the accompanying drawings.

[0058] Figure 3 is a cross-sectional view showing a vehicle air conditioning apparatus according to a first embodiment of the present invention, Figure 4 is a perspective view showing a vehicle air conditioning apparatus according to a first embodiment of the present invention, Figure 5 This is an enlarged perspective view showing a cable fixing portion of a vehicle air conditioning device according to a first embodiment of the present invention. Figure 6 yes Figure 5 Front view of Figure 7 It is a perspective view showing a state where the cable connection device is fixed to the vehicle air conditioning device according to the first embodiment of the present invention.

[0059] like Figures 3 to 7 As shown, the vehicle air conditioning device 100 according to the first embodiment of the present invention is a device for heating or cooling the internal air to perform air conditioning on the interior of the vehicle, and includes an air conditioning housing 110, a blower 200, an evaporator 102, a heater core 103 and a temperature adjustment valve 115.

[0060] An air inlet 111 is formed on the inlet side of the air conditioner casing 110 , and a defroster vent 112 a , a face vent 112 b , and a floor vent 112 c are formed on the outlet side, each of which has an opening adjusted by a mode shutter 116 .

[0061] The blower 200 is connected to the air inlet 111 of the air conditioner housing 110 to blow in or out air. The intake housing is equipped with an internal air inlet 211 for admitting internal air and an external air inlet 212 for admitting external air. The scroll of the blower 200 is equipped with a blower unit 220 comprising a blower impeller and a blower motor. An air filter 230 is located above the blower impeller.

[0062] The evaporator 102 and the heater core 103 are sequentially arranged inside the air conditioner housing 110. The temperature adjustment valve 115 is arranged between the evaporator 102 and the heater core 103 to adjust the opening of the cold air flow path bypassing the heater core 103 and the hot air flow path passing through the heater core 103.

[0063] The mode valves 116 include a defrost valve for adjusting the opening of the defrost vent 112a, a face valve for adjusting the opening of the face vent 112b, and a floor valve for adjusting the opening of the floor vent 112c. The temperature adjustment valve 115 and the mode valve 116 are connected to an actuator installed outside the air conditioner casing 110 and rotate to adjust the opening of the cold air flow path, the hot air flow path, or the opening of the flow path to each vent 112a to 112c.

[0064] To control the air conditioner, a controller is installed on the vehicle's center console. The controller consists of a switch mounted on a housing. The vehicle air conditioner is equipped with a cable connection device 500. Cable connection device 500 connects the vehicle controller's motion mechanism to the air conditioner's housing's motion mechanism via a cable 510, thereby moving the valve within the air conditioner housing 110.

[0065] The cable connection device 500 is mounted on the rear side of the controller housing, allowing the cable 510 to move when the knob is rotated. Specifically, the cable connection device 500 connects the vehicle controller's motion mechanism and the air conditioner housing 110's motion mechanism via the cable 510, whose outer circumference is surrounded by a tube, to move the valve within the air conditioner housing 110. The cable connection device 500 has an internal pulley housing for rotatably inserting the pulley, and a casing is provided on one side of the cable connection device 500, configured to insert one end of the cable 510 into the pulley housing. A stopper protrusion is elastically provided on the inside of the casing via an elastic component, and a stopper protruding from one side of the pulley has multiple stopper grooves circumferentially formed on its outer circumference, allowing the stopper protrusion to be elastically engaged.

[0066] The vehicle air conditioning system according to the first embodiment of the present invention is equipped with a cable fixing portion 300. Cable fixing portion 300 secures cable connection device 500 to air conditioning housing 110 and is integrally formed with air conditioning housing 110. Integrating cable fixing portion 300 with air conditioning housing 110 eliminates the need for additional protective mechanisms to protect cable connection device 500 during transportation of the air conditioning system, thereby reducing transportation costs.

[0067] The cable fixing portion 300 is configured as a temporary placement structure that allows the cable connection device 500 to be secured and detached. The cable fixing portion 300 facilitates securing the cable connection device 500 to the air conditioner housing 110 when transporting the air conditioner. Furthermore, if the cable connection device 500 needs to be detached from the air conditioner housing 110, such as when assembling the air conditioner in a vehicle, this facilitates detachment. This reduces the time and expense required to secure and detach the cable connection device 500 from the air conditioner housing 110.

[0068] The cable fixing portion 300 is configured as a rib protruding from the outside of the air conditioner housing 110. The cable fixing portion 300 is integrally injection-molded with the outside of the air conditioner housing 110. Therefore, the cable fixing portion 300 can both secure the cable connection device 500 and enhance the strength of the air conditioner housing 110.

[0069] The cable fixing portion 300 fixes the cable connecting device 500 connected to the controller-side motion mechanism. The cable connecting device 500 is respectively equipped with the air conditioner housing-side motion mechanism and the controller-side motion mechanism. The cable connecting device equipped with the air conditioner housing-side motion mechanism and the cable connecting device equipped with the controller-side motion mechanism can be connected to each other via a cable 510.

[0070] When transporting the air conditioner, the cable connection device attached to the air conditioner housing's kinematic mechanism is secured to the air conditioner housing without requiring an additional securing mechanism for delivery. However, during assembly, the cable connection device 500 attached to the controller's kinematic mechanism is coupled to the vehicle's panel controller, requiring an additional mechanism to secure it to the air conditioner housing 110 for delivery. Therefore, the cable securing portion 300 secures the cable connection device 500 connected to the controller's kinematic mechanism, allowing the air conditioner to be delivered without requiring an additional securing mechanism.

[0071] The cable fixing portion 300 is formed on the rear front side of the air conditioner housing 110, which is in front of the heater core 103, along the vehicle front-to-rear direction. By forming the cable fixing portion 300 on the rear front side of the air conditioner housing 110, additional space for forming the cable fixing portion 300 is eliminated, and damage and loss of the product can be reduced.

[0072] The cable fixing portion 300 is provided with a side wall portion. The side wall portion protrudes and extends from the outer side surface of the air conditioner casing 110 to be closely attached to the side surface of the cable connecting device 500, and is configured as a hook structure.

[0073] The side wall portion includes a first side wall portion 310 and a second side wall portion 340. The first side wall portion 310 and the second side wall portion 340 are formed to be spaced apart from each other along the left-right width direction of the vehicle, and the cable connection device 500 is elastically supported therebetween. An opening portion 350 for passing the cable 510 of the cable connection device 500 is formed between the first side wall portion 310 and the second side wall portion 340 at an angle relative to the separation direction. In the above description, the left-right width direction of the vehicle is Figure 6 Left and right direction in .

[0074] A predetermined space 360 ​​for accommodating the cable connection device 500 is formed between the first side wall portion 310 and the second side wall portion 340. Specifically, the first side wall portion 310 and the second side wall portion 340 are spaced apart in the left-right width direction of the vehicle and elastically support the left and right side surfaces of the cable connection device 500, respectively. The first side wall portion 310 extends and forms to conform to the shape of the cable connection device 500, surrounding the side surfaces of the cable connection device 500. This supports not only the widthwise side surfaces of the cable connection device 500, but also a portion of the lower or upper surface.

[0075] The opening 350 formed between the first side wall portion 310 and the second side wall portion 340 is along Figure 6The cable connecting device 500 is formed in a diagonal direction in the front view, that is, in a direction inclined relative to the spacing direction between the first side wall portion 310 and the second side wall portion 340. Therefore, when the cable connecting device 500 is fixed to the cable fixing portion 300, the portion for pulling out the cable 510 of the cable connecting device 500 is supported and supported at an angle relative to the elastic support direction of the side wall portion, thereby reducing the possibility of detachment, thereby further firmly fixing the cable connecting device 500.

[0076] At least one weight-reducing groove 311 or 341 is formed in the sidewall. Each weight-reducing groove 311 or 341 extends through the thickness of the sidewall. Specifically, a weight-reducing groove 311 is formed in the first sidewall 310, and a weight-reducing groove 341 is formed in the second sidewall 340. The weight-reducing grooves 311 or 341 extend through the sidewall along the thickness, or in the left-right width direction of the vehicle. The formation of these weight-reducing grooves minimizes weight and reduces manufacturing costs, while also enhancing rib rigidity.

[0077] The side wall portion is provided with a detachment prevention portion 320 that protrudes and extends in the vehicle width direction to support the front surface of the cable connection device 500. The detachment prevention portion 320 is formed at the end of the front surface of the side wall portion of the cable fixing portion 300 and supports the end of the front surface of the cable connection device 500 when the cable connection device 500 is fixed.

[0078] Furthermore, the side wall may be additionally provided with a protrusion 330 for reinforcing the strength and increasing the fixing force of the cable connection device 500. By forming the anti-detachment portion 320, the cable connection device 500 is prevented from detaching when fixed to the cable fixing portion 300, thereby increasing the fixing force.

[0079] The cable fixing portion 300 is located on a different surface from the valve driving portion that drives the valve. Specifically, the valve driving portion is located on a side surface of the air conditioner housing 110, while the cable fixing portion 300 is located on the front surface of the air conditioner housing 110. This configuration prevents interference between the valve driving portion and the cable fixing portion 300 while effectively utilizing space.

[0080] In this case, the side surface of the air conditioner casing 110, which is the right side or the left side in the vehicle width direction, is a surface of the air conditioner casing 110 opposite to the side connected to the blower 200. Furthermore, the front surface of the air conditioner casing 110, which is the rear side in the vehicle front-rear direction, is a surface facing the inside of the vehicle interior.

[0081] Reference Figure 5 and Figure 6The cable fixing portion 300 is equipped with hook portions 318 and 319 for fixing the cable 510. Preferably, two hook portions 318 and 319 are provided for each cable 510. One hook portion 318 and one hook portion 319 are provided on the first side wall portion 310 and the second side wall portion 340, respectively. The hook portions 318 and 319 are bent from the end of the side wall portion toward the outer surface of the air conditioner casing 110, thereby having a hook shape. The cable 510 is inserted and fixed to the hook portions 318 and 319, and is fixed at two positions, thereby having a stable fixing force. In addition, the cable 510 can be easily separated from the hook portions 318 and 319.

[0082] Figure 8 is a front view showing a vehicle air conditioning apparatus according to a second embodiment of the present invention, Figure 9 is a front view showing a cable fixing portion according to a second embodiment of the present invention, Figure 10 is a front view showing a cable connecting device according to a second embodiment of the present invention, Figure 11 is a perspective view showing a cable fixing portion according to a second embodiment of the present invention, Figure 12 is a perspective view showing a state where a cable connecting device is combined with a cable fixing portion according to a second embodiment of the present invention, Figure 13 is a cross-sectional view showing a cable fixing portion according to a second embodiment of the present invention, Figure 14 is a perspective view showing a state where a cable is coupled to a cable fixing portion according to a second embodiment of the present invention. Figure 15 This is a front view of a vehicle air conditioner showing a state in which a cable connection device according to a second embodiment of the present invention is coupled to a cable fixing portion.

[0083] In the following description, Figure 8 The up-down direction is the vehicle height direction, the left-right direction is the vehicle width direction, and the direction protruding from the accompanying drawings is the vehicle front-rear direction. For the sake of convenience, each direction is defined, and the present invention is not necessarily limited to the above directions.

[0084] Reference Figures 8 to 15 According to a second embodiment of the present invention, a vehicle air conditioning system includes a cable connection device 500 and a cable fixing portion 300. The cable fixing portion 300 includes a first fixing portion, a second fixing portion, and a lower end support portion 373. Furthermore, the cable connection device 500 includes a disc-shaped holder 530 that has a buckle and a shaft incorporated therein, functioning as a housing. A cable connection portion 525 for connecting a cable 510 is formed radially on one side of the holder 530.

[0085] The first fixing portion fixes the cable connection portion 525 of the cable connection device 500, and the second fixing portion fixes the bracket 530 of the cable connection device 500. The lower end support portion 373 supports the lower portion of the bracket 530 of the cable connection device 500. In other words, the lower end support portion 373 supports the side surface of the disc-shaped bracket 530.

[0086] The second fixing portion is inserted and fixed to the bracket 530 of the cable connecting device 500 along the vehicle longitudinal direction. The first fixing portion restricts the cable connecting portion 525 along the longitudinal direction of the air conditioner housing 110 to prevent the cable connecting device 500 from being separated from the cable fixing portion 300 when the cable connecting device 500 is coupled to the cable fixing portion 300.

[0087] The second fixing portion includes a protrusion protruding from the outer surface of the air conditioner housing 110 in the vehicle longitudinal direction. The bracket 530 of the cable connection device 500 includes a bracket having an insertion groove coupled to the protrusion.

[0088] The bracket portion includes a first bracket portion 528 and a second bracket portion 526. The first bracket portion 528 is formed in a direction facing the cable connection portion 525, and the second bracket portion 526 is spaced circumferentially from the first bracket portion 528. The first bracket portion 528 and the second bracket portion 526 each extend radially from the outer circumference of the bracket 530. Insertion slots 529 and 527 are formed in the first bracket portion 528 and the second bracket portion 526, respectively, extending in the front-to-rear direction of the vehicle.

[0089] The protrusions include a first protrusion 372, which is inserted into the insertion slot 529 of the first bracket portion 528, and a second protrusion 371, which is inserted into the insertion slot 527 of the second bracket portion 526. The first and second protrusions 372 and 371 extend from the outer surface of the air conditioner housing 110 toward the rear of the vehicle. The second protrusion 371 is arranged to face the lower end support portion 373 in the vehicle height direction (vertical direction), while the first protrusion 372 is arranged to face the first fixing portion in the vehicle width direction (lateral direction).

[0090] The first fixing portion is equipped with an elastic support portion 374. The elastic support portion 374 elastically supports both sides of the cable connection portion 525, thereby blocking and restricting at least a portion of the cable connection portion 525 in the vehicle's front-to-rear direction. To accommodate the cable connection portion 525, a recessed seating groove 377 is formed in the elastic support portion 374. The elastic support portion 374 comprises a pair of hook-shaped components spaced apart in the height direction, each of which exhibits an elastic restoring force in the direction of closing. When the cable connection portion 525 is pressed toward the elastic support portion 374, the hook-shaped components open and then close again due to the elastic restoring force, thereby securing the cable connection portion 525.

[0091] The first protrusion 372 and the second protrusion 371 restrict the vehicle's height and width as the bracket 530 of the cable connection device 500 is inserted. The elastic support 374 restricts the vehicle's fore-aft movement as the cable connection portion 525 of the cable connection device 500 is secured. A predetermined space 360 ​​is formed within the area surrounded by the lower support 373, the first protrusion 372, the second protrusion 371, and the elastic support 374. The cable connection device 500 is mounted within this space 360.

[0092] The cable fixing portion 300 is also equipped with cable insertion portions 375 and 379 for fixing the cable 510. The cable insertion portions 375 and 379 are arranged above the first fixing portion and the second fixing portion. In this case, the cable 510 of the left cable connection device 500 is fixed to the right cable insertion portion 375 and 379, and the cable 510 of the right cable connection device 500 is fixed to the left cable insertion portion 375 and 379.

[0093] One cable insertion portion 375 has a receiving groove 376 formed inside for inserting a cable 510, and is positioned above the elastic support portion 374. Another cable insertion portion 379 is positioned above and adjacent to the second protrusion 371. The cables 510 of each cable connection device 500 are staggered in the left-right direction, allowing the cables 510 to twist at least once. The twisting force of the cables 510 helps secure the cable connection device 500. Consequently, the securing force of the cable connection device 500 can be further enhanced.

[0094] The cable connection device 500 is inserted into the first protrusion 372 and the second protrusion 371 formed on the air conditioner housing 110 and pressed against the elastic support portion 374 with a predetermined force, allowing it to be easily attached to the cable fixing portion 300 with a single touch. The cable connection device 500 can be easily detached by slightly expanding the elastic support portion 374 with a predetermined force. The first and second fixing portions securely fasten the cable connection device 500 to the air conditioner housing 110, enhancing the attachment strength and preventing damage that could occur from detaching the cable connection device 500 during transportation.

[0095] The vehicle air conditioning system according to the present invention has been described above with reference to the embodiments shown in the accompanying drawings. However, this is merely exemplary, and those skilled in the art will readily appreciate that various modifications and equivalent embodiments are possible. Therefore, the true scope of protection should be determined by the technical concepts set forth in the claims.
