Description

Technical Field

[0001] The utility model relates to the technical field of vehicle air conditioning, and in particular to an air intake structure of a vehicle air conditioning. The utility model also relates to a vehicle air conditioning having the air intake structure of the vehicle air conditioning, and a vehicle equipped with the vehicle air conditioning. Background Art

[0002] In the related art, the air intake part of the vehicle air conditioner generally has an external circulation air outlet and an internal circulation air outlet. The external circulation air outlet is used for the air outside the vehicle to enter the air conditioner and enter the vehicle after being processed by the air conditioner, while the internal circulation air outlet is used for the air inside the vehicle to enter the air conditioner and return to the vehicle after being processed by the air conditioner. Usually, the circulating air inside the vehicle entering through the internal circulation air outlet can be called "circulating air", and correspondingly, the air outside the vehicle entering from the external circulation air outlet can be called "fresh air".

[0003] At present, the air intake of the internal and external circulation air vents is mainly controlled by a damper arranged inside the air intake part, and depending on the position of the damper, the air intake of the air conditioner can generally be in an internal circulation mode in which only the air inside the vehicle circulates, an external circulation mode in which only the air outside the vehicle enters, or an internal and external circulation mixed air mode in which both the internal and external air circulate at the same time.

[0004] However, when in the internal and external circulation mixed air mode, the existing vehicle air conditioner is prone to cross-wind problems due to the direct entry of outside air into the vehicle through the internal circulation vents, affecting the air quality in the vehicle and reducing the riding comfort of the driver and passengers, which is not conducive to improving the use quality of the vehicle air conditioner. In addition, when in the external circulation mode, regardless of whether the air conditioner is in cooling or heating conditions, since the air conditioner is always processing the air entering from outside the vehicle, it is also easy to cause the temperature adjustment speed in the vehicle to be slow and the air conditioner energy consumption to be high, which is also not conducive to improving the use quality of the vehicle air conditioner. Utility Model Content

[0016] Furthermore, the compensating damper is made of rubber or foam.

[0017] Furthermore, a sealing sponge is provided at the outer circulation air outlet, and the sealing sponge is arranged around the outer circulation air outlet and is used to seal the gap between the outer circulation air outlet and the vehicle body.

[0044] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0045] Embodiment 1

[0046] The present embodiment relates to an air intake structure for a vehicle air conditioner, which can avoid the problem of internal and external circulation cross-wind when the air conditioner is in an internal and external circulation mixed air mode. At the same time, it can also achieve rapid adjustment of the temperature in the vehicle when the air conditioner is in an external circulation mode, which is beneficial to improving the use quality of the vehicle air conditioner.

[0047] In terms of overall structure, Figures 1 to 3 , and combined with Fig. 9 As shown in the figure, the vehicle air conditioning air intake structure of this embodiment includes an air intake shell 1 provided with an external circulation air outlet 2 and an internal circulation air outlet 3, an external circulation air door 8 and an internal circulation air door 4 arranged in the air intake shell 1, and a wind shield 9 arranged in the air intake shell 1.

[0048] The wind shield 9 is located on one side of the inner circulation damper 4, and when the inner circulation damper 4 rotates to abut against the wind shield 9, the air inlet housing 1 can be separated into an independent inner circulation air duct 100 and an outer circulation air duct 200 by the inner circulation damper 4 and the wind shield 9. The inner circulation air duct 100 is connected with the inner circulation air port 3, and the outer circulation air duct 200 is connected with the outer circulation air port 2. A compensation air port 5 is provided on the air inlet housing 1, and a compensation damper 6 is also provided at the compensation air port 5 for unidirectional conduction into the outer circulation air duct 200.

[0049] At this time, as set above, by setting the wind shield 9, and when the inner circulation damper 4 is against it, the air inlet housing 1 can be separated into independent inner circulation duct 100 and outer circulation duct 200, and this embodiment can avoid the problem of inner and outer circulation cross-wind when the air conditioner is in the inner and outer circulation mixed air mode. At the same time, by setting the compensation air port 5, and setting the compensation damper 6 that unidirectionally conducts into the outer circulation air duct 200 at the supplementary air port 5, this embodiment can also compensate a part of the air inside the vehicle to the outer circulation air duct 200 when the air conditioner is in the outer circulation mode, which helps to achieve rapid adjustment of the temperature inside the vehicle, and can achieve the effect of improving the use quality of the vehicle air conditioner.

[0050] Based on the above overall introduction, specifically, continue to combine Figures 4 to 5 As shown in the figure, as a preferred implementation form, the air inlet housing 1 of this embodiment mainly includes a first half shell 101 and a second half shell 102 that are snapped together, and a fresh air duct 103 connected to the first half shell 101 and the second half shell 102 that are snapped together.

[0051] The above-mentioned outer circulation air outlet 2 is located on the fresh air duct 103, and the inner circulation air outlet 3 is respectively provided on the first half shell 101 and the second half shell 102. At this time, it can be understood that by making the air inlet housing 1 consist of two half shells connected by buckling and the fresh air duct 103, it can facilitate the design and preparation of the air inlet housing 1, and also facilitate the assembly and arrangement of various related parts inside the air inlet housing 1. In addition, by providing the fresh air duct 103, it also helps the air inlet structure of this embodiment to be connected with the fresh air outlet on the vehicle body (usually located at the front panel position in the vehicle body), so as to facilitate the overall arrangement of the vehicle air conditioner in the vehicle.

[0052] In this embodiment, during specific implementation, the first half shell 101, the second half shell 102 and the fresh air duct 103 can generally be made of injection-molded plastic parts, and the first half shell 101 and the second half shell 102 that are snapped together can be fixedly connected by, for example, snapping, screwing, etc., and the fresh air duct 103 and the two half shells can also be fixedly connected together by, for example, snapping, screwing, etc.

[0053] It should be noted that, in addition to making the above-mentioned air inlet shell 1 composed of the first half shell 101, the second half shell 102 and the fresh air duct 103, of course, in some other implementation forms, the air inlet shell 1 of this embodiment can also adopt other structural forms, as long as it can realize the internal and external circulation air intake requirements of the vehicle air conditioner and can meet the setting and application requirements of the wind shield 9, compensation air outlet 5 and compensation damper 6 of this embodiment.

[0054] In addition, in addition to setting the internal circulation air outlet 3 on both the first half shell 101 and the second half shell 102, it is convenient to set the internal circulation air outlet 3 and better ensure the air intake during the internal circulation. Under the condition of meeting the internal circulation air intake demand, according to the structural design of the first half shell 101 and the second half shell 102, it is of course possible to set the internal circulation air outlet 3 only on the first half shell 101 or the second half shell 102.

[0055] In this embodiment, based on the arrangement of the compensation air outlet 5 on the air inlet housing 1, specifically, for example, the compensation air outlet 5 can be arranged as follows: Figures 1 to 5 As shown in FIG. 1 , the first half shell 101 and the second half shell 102 are both provided with compensation air ports 5 , and the compensation air ports 5 on the first half shell 101 and the second half shell 102 are arranged opposite to each other and are both located at the side of the air inlet housing 1 .

[0056] In this way, the compensation air ports 5 are arranged on the two half shells, and the compensation air ports 5 on the two half shells are arranged relative to each other and are both located at the side of the air inlet housing 1, which can facilitate the molding of the compensation air ports 5 and also facilitate the installation and arrangement of the compensation air door 6. In addition, by arranging the compensation air ports 5 on both half shells, of course, it can also ensure the compensation air volume entering the external circulation air duct 200 through the compensation air ports 5.

[0057] It is worth pointing out that, in addition to locating the compensation air outlet 5 on the side of the air inlet shell 1 and providing the compensation air outlet 5 on both half shells, in some embodiments, the compensation air outlet 5 on each half shell may also be provided at other positions, or the compensation air outlet 5 may be provided on only one of the half shells.

[0058] In addition, in addition to providing the compensating air outlet 5 on the air inlet shell 1, further, in some embodiments, the present embodiment may also provide the compensating air outlet 5 on the wind shield 9 at the same time, and provide the compensating air door 6 which unidirectionally conducts into the external circulation air duct 200 at the supplementary air outlet 5, or, may provide only the compensating air outlet 5 with the compensating air door 6 on the wind shield 9, so as to have the same effect of compensating the air inside the vehicle into the external circulation air duct 200.

[0059] In this embodiment, the compensation damper 6 arranged on each half shell is still taken as an example. Figures 1 to 5 , and combined with Figure 7 As shown in , the compensation air outlet 5 may be, for example, a rectangular opening, and the shape of the compensation air door 6 is arranged according to the shape of the compensation air outlet 5 .

[0060] At the same time, as an exemplary setting form, the compensation damper 6 of the present embodiment can be set on the side of the air inlet shell 1 facing the external circulation air duct 200, for example, through the damper fixing strip 11, and the compensation damper 6 can block the compensation air outlet 5 in a natural state, and when the air pressure in the external circulation air duct 200 is lower than the preset threshold value, the compensation damper 6 can unidirectionally conduct air into the external circulation air duct 200.

[0061] At this time, by setting the compensating damper 6 on the air inlet housing 1 through the damper fixing strip 11, it has the advantages of simple structure and easy design and assembly. In the specific implementation, the damper fixing strip 11 can be fixed to the air inlet housing 1 by, for example, snap-fitting or screwing, so as to position the top of the compensating damper 6 on the air inlet housing 1.

[0062] It is understandable that when the compensation air outlet 5 is provided on the wind shield 9, the compensation damper 6 on the wind shield 9 can also be provided in the same manner as above, and is provided on the side of the wind shield 9 facing the external circulation air duct 200 through the damper fixing strip 11.

[0063] In addition, in a specific implementation, as a preferred implementation form, the compensation damper 6 of this embodiment can be made of rubber or foam, for example.

[0064] In this way, the compensating damper 6 is made of rubber or foam, for example, which not only facilitates the preparation of the compensating damper 6 but also enables the compensating damper 6 to have better elasticity. Thus, on the one hand, when the air pressure in the external circulation air duct 200 is relatively low (relative to the interior of the vehicle), the compensating damper 6 can be reliably opened to achieve one-way conduction into the external circulation air duct 200. On the other hand, when the air pressure in the external circulation air duct 200 is not lower than that in the vehicle, the compensating damper 6 can fit better to the peripheral edge of the compensating air outlet 5 to achieve the closure of the supplementary air outlet 5.

[0065] In the present embodiment, it should be pointed out that, in addition to making the compensating damper 6 arranged on the air inlet housing 1 or the wind shield 9 through the damper fixing strip 11, and making the compensating damper 6 adopt rubber or foam material, of course, in other embodiments, the compensating damper 6 can also be made of other materials, and correspondingly, the compensating damper 6 can be arranged on the air inlet housing 1 or the wind shield 9 in other ways, as long as the compensating damper 6 can block the compensating air outlet 5 in a natural state, and can unidirectionally conduct air into the external circulation air duct 200 when the air pressure in the external circulation air duct 200 is lower than the preset threshold value.

[0066] Among them, the air pressure in the above-mentioned external circulation air duct 200 is lower than a preset threshold value, and the preset threshold value can be determined in the air intake structure of the vehicle air conditioner, or in other words, in the overall system design of the vehicle air conditioner, based on the air intake capacity of the vehicle air conditioner during external circulation, and the selection of the structure and material of the compensation damper 6. As long as the compensation damper 6 can be unidirectionally conducted into the external circulation air duct 200 when the vehicle air conditioner is in the external circulation mode, so that the air inside the vehicle can enter the external circulation air duct 200, it will be sufficient.

[0067] In this embodiment, with respect to the wind shield 9 disposed in the air inlet housing 1, as a preferred implementation form, the wind shield 9 can be, for example, integrally formed on the air inlet housing 1. At this time, by integrally forming the wind shield 9 on the air inlet housing 1, it is convenient to design and prepare the wind shield 9, and even the main structural part of the entire air inlet structure. At the same time, since the wind shield 9 is integrally formed on the air inlet housing 1, of course, the assembly process of the wind shield 9 can be omitted, which helps to improve the assembly efficiency of the air inlet structure.

[0068] Based on the wind shield plate 9 being integrally formed on the air inlet housing 1, specifically, the air inlet housing 1 of this embodiment still includes a first half shell 101 and a second half shell 102 that are buckled and connected, and still referring to Figure 4 and Figure 5As shown, in this embodiment, for example, the windshield 9 can also be divided into two parts to be integrally formed with the two half shells respectively, and when the two half shells are buckled and connected, the parts of the windshield 9 on the two half shells can also be spliced ​​to form the whole windshield 9.

[0069] It is worth noting that, in addition to partially molding the windshield 9 on both the first half shell 101 and the second half shell 102, in some embodiments, the windshield 9 may be completely molded on one of the half shells. At the same time, in addition to integrally molding the windshield 9 on the air inlet housing 1, it is also feasible to make it separately and fix it in the air inlet housing 1 by means of snap connection or screw connection.

[0070] In the present embodiment, in view of the fact that the external circulation air outlet 2 needs to be connected to the fresh air outlet on the vehicle body, at this time, in order to ensure the sealing of the connection position between the external circulation air outlet 2 and the fresh air outlet on the vehicle body, as a preferred implementation form, a sealing sponge 12 can be provided at the external circulation air outlet 2, and the sealing sponge 12 is provided around the external circulation air outlet 2 and is used to seal the gap between the external circulation air outlet 2 and the vehicle body.

[0071] In specific implementation, based on the fact that a fresh air duct 103 can be set in the air inlet housing 1, the sealing sponge 12 can generally be set on the sponge installation surface 103a at the end of the fresh air duct 103, and the sealing sponge 12 can specifically adopt a conventional sponge structure that can meet the sealing requirements.

[0072] However, as a preferred exemplary structural form, combined with Figure 8 As shown in , in addition to adopting a conventional sponge structure, further, in this embodiment, for example, the sealing sponge 12 may include a bottom sponge 1201 and an upper sponge 1202 stacked together.

[0073] The width k of the bottom sponge 1201 is greater than that of the upper sponge 1202, and the height h of the upper sponge 1202 is greater than that of the bottom sponge 1201. The bottom sponge 1201 and the upper sponge 1202, as well as the bottom sponge 1201 and the sponge installation surface 103a, can be bonded and connected. When the external circulation air outlet 2 is connected to the fresh air outlet on the vehicle body, the upper sponge 1202 can be pressed against the front wall sheet metal in the vehicle body, and the bottom sponge 1201 can be pressed against the front wall heat insulation pad to form a double-layer sealing form.

[0074] By adopting the above-mentioned double-layer sealing form, it can not only play a good sealing and waterproofing role, but also effectively isolate the front cabin noise from entering the car through the air-conditioning fresh air vents, which helps to improve the sound insulation effect of the whole vehicle and reduce the noise inside the car.

[0075] In the present embodiment, the internal circulation damper 4 and the external circulation damper 8 can both adopt the damper structure commonly used in existing vehicle air conditioners, and similar to the damper setting form in existing vehicle air conditioners, the internal circulation damper 4 can be rotatably installed in the air inlet shell 1 using the internal circulation damper shafts 401 at both ends and the internal circulation damper mounting holes 1b on the two half shells. Similarly, the external circulation damper 8 can also be rotatably installed in the air inlet shell 1 using the external circulation damper shafts 801 at both ends and the external circulation damper mounting holes 1a on the two half shells.

[0076] After the inner circulation damper 4 and the outer circulation damper 8 are installed in the air inlet housing 1, the damper driving form is still similar to that of the existing vehicle air conditioner. The inner circulation damper 4 and the outer circulation damper 8 of this embodiment can use the damper shaft at one end to be connected to the damper driving mechanism (generally composed of a motor and a corresponding rocker arm and other transmission structures) arranged outside the air inlet housing 1, thereby being able to reciprocate under the drive of the damper driving mechanism.

[0077] In addition, it is worth noting that, similar to the related structures in the existing vehicle air conditioners, in the vehicle air conditioner air intake structure of this embodiment, a filter installation groove 10 is also provided on the air intake housing 1, and the filter installation groove 10 is formed on the inner wall of the two half shells, and the filter 7 is installed and arranged through the filter installation groove 10. Along the air intake direction of the vehicle air conditioner, the installed filter 7 is generally located downstream of the above-mentioned inner circulation air duct 100 and outer circulation air duct 200, and upstream of the fan in the vehicle air conditioner, and the air entering through the inner circulation air duct 100 and the outer circulation air duct 200 all enters the filter 7, and enters the vehicle after being filtered by the filter 7.

[0078] The vehicle air conditioning air intake structure of this embodiment is further combined with Figure 3 and Fig. 9 As shown, when the damper driving mechanism drives the inner circulation damper 4 to rotate clockwise and abut against the wind shield 9, the inner circulation air outlet 3 is opened, and at the same time, the damper driving mechanism drives the outer circulation damper 8 to rotate counterclockwise to close the outer circulation air outlet 2, the inner circulation mode of the vehicle air conditioner can be realized. When the damper driving mechanism drives the inner circulation damper 4 to rotate counterclockwise, away from the wind shield 9, and close the inner circulation air outlet 3, and at the same time, the damper driving mechanism drives the outer circulation damper 8 to rotate clockwise to open the outer circulation air outlet 2, the outer circulation mode of the vehicle air conditioner can be realized. When the damper driving mechanism drives the inner circulation damper 4 to rotate clockwise, abuts against the wind shield 9, and opens the inner circulation air outlet 3, and at the same time, the damper driving mechanism drives the outer circulation damper 8 to rotate counterclockwise to any angle, the inner and outer circulation mixed air mode of the vehicle air conditioner can be realized.

[0079] When the vehicle air conditioner is in the internal and external circulation mixed air mode, the damper driving mechanism drives the internal circulation damper 4 to rotate clockwise to open the internal circulation air outlet 3, and the damper driving mechanism drives the external circulation damper 8 to rotate clockwise to open the external circulation air outlet 2. When the vehicle is in a high-speed driving state, due to the external wind pressure, the outside air will enter the air inlet housing 1 through the opened external circulation air outlet 2. At this time, if the vehicle air conditioner is not in a working state or a low-gear working state, only a small amount of the outside air entering the air inlet housing 1 can pass through the filter 7 and enter the vehicle air conditioner. Most of the outside air entering the air inlet housing 1 is blocked by the filter 7. If the air inlet structure of the vehicle air conditioner is not provided with a windshield 9, it is obvious that the outside air blocked by the filter 7 will pass through the lower side of the internal circulation damper 4. Since the internal circulation air outlet 3 is in an open state, this part of the outside air will directly enter the vehicle through the opened internal circulation air outlet 3, which will seriously affect the air quality in the vehicle and reduce the comfort of the driver and passengers.

[0080] By setting the above-mentioned wind shield 9, it can just block the gap on the lower side of the inner circulation damper 4, and can block the outside air passing through the lower side of the inner circulation damper 4, and can isolate the inner and outer circulation air ducts, thereby preventing the outside air from directly entering the car when the car air conditioner is in the internal and external circulation mixed air mode.

[0081] In addition, when the vehicle air conditioner is in the internal circulation mode, after the air in the vehicle is sucked into the air inlet housing 1 through the internal circulation air port 3, due to the blocking effect of the windshield 9, the air in the vehicle cannot pass through the windshield 9 and enter the side of the external circulation air duct 200. At this time, it is obvious that no wind will pass through the part of the filter 7 corresponding to the external circulation air duct 200. In order to ensure the uniformity of wind speed at various locations of the filter 7 in the internal circulation mode, the above-mentioned compensation air port 5 comes into play at this time. Due to the effect of wind pressure, a part of the air in the vehicle blows open the compensation air door 6, passes through the compensation air port 5, enters the external circulation air duct 200, and enters the air conditioner through the filter 7, which can ensure the uniformity of wind speed at various locations of the filter 7, which is conducive to improving the service life of the filter 7.

[0082] In addition, when the vehicle air conditioner is in the external circulation mode, no matter whether the air conditioner is cooling or heating, and especially when the vehicle air conditioner is working at a higher level, at this time, the compensation damper 6 will also be blown open by the wind pressure to a certain angle, and a part of the air inside the vehicle will enter the external circulation air duct 200. In this way, a part of the air inside the vehicle can be compensated in the external circulation mode to achieve rapid adjustment of the temperature inside the vehicle, thereby achieving the effect of reducing the energy consumption of the whole vehicle and increasing the endurance of the whole vehicle.

[0083] To sum up, the vehicle air-conditioning air intake structure of this embodiment, by providing a wind shield 9 and an air-compensating structure composed of a compensation air outlet 5 and a compensation damper 6, can not only avoid the problem of internal and external circulation cross-wind when the air-conditioning is in the internal and external circulation mixed air mode, but also can realize rapid adjustment of the temperature in the vehicle when the air-conditioning is in the external circulation mode, thereby helping to improve the use quality of the vehicle air-conditioning.
