DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0028] In the description of this application, it should be understood that if the terms "upper", "lower", "left", "right", etc. indicate an orientation or positional relationship based on the orientation or positional relationship shown in the drawings, it is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as a limitation on this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0029] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as suggesting or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0030] In the description of this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined.

[0031] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.

[0032] At present, vehicles have been widely popularized in ordinary families and integrated into people's daily lives, and people use vehicles to travel more and more frequently.

[0033] In order to improve the air quality in the car, an air filter is usually installed in the air conditioner of the vehicle. Since the air filter needs to purify the air continuously, the filter element in the air filter needs to be replaced frequently to ensure the air purification effect.

[0034] However, since the filter element is in the hot and humid environment inside the air conditioner, the filter element becomes soft. Thus, when the filter element installation port is opened, the filter element is easily stuck in the air filter device and is difficult to be pulled out. This makes the filter element replacement process inconvenient.

[0035] Based on the above problems, the embodiments of the present application propose an air filter device and a vehicle to facilitate improving the convenience of filter element replacement.

[0036] In a first aspect, the present application provides an air filter device 10. Figures 1 to 3 As shown, the air filter device 10 includes a first housing 100, a cover plate 200, a filter unit 300 and a clamping mechanism 400. The first housing 100 has an accommodating chamber (not shown) inside, and the first housing 100 is provided with an opening 102 communicating with the accommodating chamber. The cover plate 200 is detachably covered on the opening 102, the filter unit 300 is arranged in the accommodating chamber, and the clamping mechanism 400 is connected to the cover plate 200, and the clamping mechanism 400 is configured to clamp or release the filter unit 300 so that the filter unit 300 is fixed to the cover plate 200 or separated from the cover plate 200.

[0037] In the present application, the air filter device 10 includes a first housing 100, a cover plate 200, a filter unit 300 and a clamping mechanism 400. The first housing 100 is the outer shell of the air filter device 10, and has an accommodating cavity for arranging the filter unit 300 inside, and an opening 102 communicating with the accommodating cavity is arranged on the outer surface. The cover plate 200 covers the opening 102 in a detachable manner, thereby realizing the connection between the cover plate 200 and the first housing 100. The detachable manner can be, for example, a snap connection, a connector connection, a magnetic connection, etc., which is not limited in the present application.

[0038] The filter unit 300 is used to filter the air. Figure 3 As shown, the filter unit 300 may include, for example, a fixing portion 301 and a filter portion 302. The fixing portion 301 may be, for example, a frame, a connecting plate, etc., and the filter portion 302 may be, for example, a filter screen.

[0039] The clamping mechanism 400 is connected to the cover plate 200, and the clamping mechanism 400 can clamp or release the filter unit 300, so that the filter unit 300 and the cover plate 200 are fixedly connected or separated. In other words, the clamping mechanism 400 can clamp the filter unit 300. When the clamping mechanism 400 clamps the filter unit 300, the filter unit 300 is fixedly connected to the cover plate 200 through the clamping mechanism 400. When the clamping mechanism 400 releases the filter unit 300, the filter unit 300 and the cover plate 200 are separated, and the filter unit 300 can be removed from the cover plate 200.

[0040] The air filter device 10 of the present application is provided with a clamping mechanism 400 on the cover plate 200. The clamping structure 400 can clamp or release the filter unit 300. When the clamping mechanism 400 clamps the filter unit 300, the filter unit 300 is fixed on the cover plate 200. At this time, the cover plate 200 can serve as a fixing and connecting structure of the filter unit 300 in the accommodating chamber. That is, the filter unit 300 relies on the cover plate 200 to achieve fixation and installation in the accommodating chamber. In the case where the clamping mechanism 400 clamps the filter unit 300, when the cover plate 200 is installed in place, the position of the filter unit 300 in the accommodating chamber is also determined accordingly. If the filter unit 300 needs to be replaced, it is only necessary to disassemble the cover plate 200 to take the filter unit 300 out of the accommodating chamber. After being taken out, the clamping mechanism 400 releases the filter unit 300, and a new filter unit 300 is taken out and clamped on the clamping mechanism 400, and finally the cover plate 200 is reinstalled on the first shell 100, thereby realizing the disassembly and replacement of the filter unit 300, which is conducive to improving the convenience of replacing the filter unit 300.

[0041] It is easy to understand that Figure 3 As shown, since the clamping mechanism 400 cannot clamp the entire structure of the filter unit 300, when the cover plate 200 covers the opening 102, in order to improve the stability of the filter unit 300 in the accommodating chamber, in some embodiments, a limiting groove (not shown) can be set inside the first housing 100, and one end of the filter unit 300 away from the clamping mechanism 400 is placed in the limiting groove. In this way, the limiting groove only serves to limit the end of the filter unit 300 away from the clamping mechanism 400 from moving in the accommodating chamber, and does not play a role in fixing and clamping the filter unit 300, thereby improving the stability of the filter unit 300 in the accommodating chamber while ensuring the convenience of replacing the filter unit 300. In addition, in the present application, clamping means that the filter unit 300 is in a clamped state on the clamping mechanism 400 and will not fall off, so that a certain stability of the filter unit 300 can be maintained.

[0042] In some embodiments, Figure 1As shown, the air filter device 10 further includes a second housing 500, which is connected to the first housing 100, a blower (not shown) is arranged inside the second housing 500, and an air outlet 510 is arranged on the side of the second housing 500 away from the first housing 100. In this way, the external air or the air inside the vehicle enters the accommodating cavity through the first housing 100, and after being filtered by the filter unit 300, it is sent to other structures of the air conditioner such as the evaporator and the heat exchanger through the blower, and finally sent to the interior space of the vehicle, so that the air inside the vehicle can be purified on the one hand, and the cooling and heating functions of the air conditioner can be realized on the other hand.

[0043] In some embodiments, Figure 2 and Figure 3 As shown, the clamping mechanism 400 includes a clamping assembly 410 and a driving assembly 420. The clamping assembly 410 is used to clamp the filter unit 300, and the driving assembly 420 is used to drive the clamping assembly 410 to clamp or release the filter unit 300. In this way, by manipulating the driving assembly 420, the clamping assembly 410 can clamp or release the filter unit 300, which is conducive to improving the convenience of the clamping mechanism 400.

[0044] In some embodiments, Figures 2 to 4 As shown, the clamping assembly 410 includes at least one sliding rod 411 connected to the side surface of the cover plate 200 close to the accommodating chamber, and an upper clamping plate 412 and a lower clamping plate 413 mounted on the sliding rod 411, one end of the filter unit 300 is located between the upper clamping plate 412 and the lower clamping plate 413, and the driving assembly 420 includes a first connecting rod 421 and a first slider 422, one end of the first connecting rod 421 is connected to one of the upper clamping plate 412 and the lower clamping plate 413, and the other end is connected to the first slider 422, and the first slider 422 is located on the side of the cover plate 200 away from the accommodating chamber.

[0045] This embodiment proposes one of the structures of the clamping assembly 410 and the driving assembly 420. The clamping assembly 410 includes at least one slide bar 411, an upper clamping plate 412, and a lower clamping plate 413. At least one slide bar 411 means that the number of the slide bars 411 can be one, or two or more. When the number of the slide bars 411 is two or more, the slide bars 411 are arranged at intervals along the length direction of the cover plate 200, thereby facilitating the stability of the upper clamping plate 412 and the lower clamping plate 413 sliding on the slide bars 411.

[0046] Since one end of the filter unit 300 is located between the upper clamping plate 412 and the lower clamping plate 413, when the upper clamping plate 412 and the lower clamping plate 413 are close to each other, the two can clamp the filter unit 300; when the upper clamping plate 412 and the lower clamping plate 413 are away from each other, the two can loosen the filter unit 300. Optionally, the upper clamping plate 412 and the lower clamping plate 413 are L-shaped, so that the stability and reliability of the clamping can be improved. Of course, the upper clamping plate 412 and the lower clamping plate 413 can also be other shapes and structures, as long as they can clamp the filter unit 300 in the up and down directions. Optionally, in order to prevent the upper clamping plate 412 and the lower clamping plate 413 from detaching from the sliding rod 411, blocking blocks 4111 are provided at both ends of the sliding rod 411.

[0047] The driving assembly 420 includes a first connecting rod 421 and a first sliding block 422. When a person pushes the first sliding block 422 to move, the first sliding block 422 drives the first connecting rod 421 to move, thereby causing the upper clamping plate 412 or the lower clamping plate 413 connected to the first connecting rod 421 to move on the sliding rod 411, so that the upper clamping plate 412 and the lower clamping plate 413 are moved closer to or farther from each other. This is conducive to improving the convenience of the clamping assembly 410 clamping the filter unit 300.

[0048] In some embodiments, Figure 2 As shown, the clamping assembly 410 also includes a first gear 414, a first rack 415 and a second rack 416. The first gear 414 is rotatably connected to a side surface of the cover plate 200 close to the accommodating cavity, the first rack 415 is connected to the upper clamp plate 412, and the second rack 416 is connected to the lower clamp plate 413. The first rack 415 and the second rack 416 are located on opposite sides of the first gear 414 and are both engaged with the first gear 414.

[0049] In this embodiment, the clamping assembly 410 further includes a first gear 414, a first rack 415, and a second rack 416. When the first slider 422 and the first connecting rod 421 only drive one of the upper clamping plate 412 and the lower clamping plate 413 to move on the slide bar 411, the structure of the first gear 414, the first rack 415, and the second rack 416 can realize the synchronous movement of the other of the upper clamping plate 412 and the lower clamping plate 413 on the slide bar 411. For example, the connection between the first connecting rod 421 and the upper clamping plate 412 is used as an example for explanation. When the first slider 422 and the first connecting rod 421 drive the upper clamping plate 412 to move toward the lower clamping plate 413, the first rack 415 will move relative to the first gear 414, thereby causing the first gear 414 to rotate. In this way, the first gear 414 will drive the second rack 416 to move. Since the first rack 415 and the second rack 416 are located on opposite sides of the first gear 414, the second rack 416 can drive the lower clamping plate 413 to move toward the upper clamping plate 412, and the two can achieve synchronous movement close to each other. The principle of the first slider 422 and the first connecting rod 421 driving the upper clamping plate 412 to move away from the lower clamping plate 413 is similar to the above, and will not be repeated here. Therefore, this embodiment, by setting the first gear 414, the first rack 415 and the second rack 416, can simultaneously realize the movement of the upper clamping plate 412 and the lower clamping plate 413 with only one first slider 422 and the first connecting rod 421, thereby facilitating the convenience of the clamping mechanism 400 clamping the filter unit 300, simplifying the structure of the driving assembly 420, and reducing costs.

[0050] In the above embodiment, when the first gear 414, the first rack 415 and the second rack 416 are provided, the driving assembly 420 adopts a method of driving one of the upper clamping plate 412 and the lower clamping plate 413, so as to realize the synchronous movement of the other clamping plate. It is easy to understand that the driving assembly 420 can also be other structures, for example, the method of directly driving the first gear 414 to rotate forward or reverse can be adopted to realize the synchronous movement of the upper clamping plate 412 and the lower clamping plate 413. Specifically, in another embodiment, the driving assembly 420 includes a rotating disk and a connecting rod (not shown in the figure), the rotating disk is connected to the first gear 414 through the connecting rod, and the rotating disk and the first gear 414 are located on opposite sides of the cover plate 20. In this way, the rotating disk can be directly rotated, thereby driving the first gear 414 to rotate, and then driving the first rack 415 and the second rack 416 to move respectively, and finally driving the upper clamping plate 412 and the lower clamping plate 413 to move at the same time.

[0051] Of course, in the present application, in addition to setting the first gear 414, the first rack 415 and the second rack 416, other methods can also be used to achieve the synchronous movement of the upper clamping plate 412 and the lower clamping plate 413 so that the upper clamping plate 412 and the lower clamping plate 413 clamp or release the filter unit 300.

[0052] For example, in other embodiments, the driving assembly 420 includes a first connecting rod 421, a second connecting rod (not shown), a first slider 422, and a second slider (not shown). One end of the first connecting rod 421 is connected to the upper clamping plate 412, and the other end is connected to the first slider 422. One end of the second connecting rod is connected to the lower clamping plate 413, and the other end is connected to the second slider. The first slider 422 and the second slider are both located on the side of the cover plate 200 away from the accommodating cavity. In this way, the upper clamping plate 412 can be driven to move on the slide bar 411 by the first slider 422 and the first connecting rod 421, and the lower clamping plate 413 can be driven to move on the slide bar 411 by the second connecting rod and the second slider. Therefore, by setting two connecting rods and two sliders, the synchronous movement of the upper clamping plate 412 and the lower clamping plate 413 can also be achieved.

[0053] It should be noted that the driving assembly 420 and the clamping assembly 410 of the present application may also be other structures, as long as they can realize the relative or opposite movement of at least one of the upper clamping plate 412 and the lower clamping plate 413 on the sliding rod 411, and the present application does not impose any restrictions on this.

[0054] In some embodiments, Figure 4 As shown, the clamping mechanism 400 further includes a locking assembly 430, which is used to lock the clamping assembly 410 so that the clamping assembly 410 maintains a clamping state for the filter unit 300. Thus, when the cover plate 200 is covered on the opening 102, the clamping assembly 410 can always be kept in a state of clamping the filter unit 300, preventing the filter unit 300 from falling off the clamping assembly 410, thereby facilitating the improvement of the reliability and stability of the clamping assembly 410 clamping the filter unit 300, and further facilitating the improvement of the filtering effect of the air filter device 10.

[0055] In some embodiments, Figure 4 As shown, the locking assembly 430 includes a slot 431 and a block 432, one of which is disposed on the first slider 422, and the other is disposed on a side surface of the cover plate 200 away from the accommodating cavity, and the block 432 can be engaged in the slot 431 or detached from the slot 431.

[0056] This embodiment proposes one structure of the locking assembly 430. The locking assembly 430 includes a slot 431 and a block 432. When the first slider 422 is driven to move so that the upper clamping plate 412 and the lower clamping plate 413 clamp the filter unit 300, the block 432 can extend into the slot 431, thereby locking the position of the first slider 422. As a result, the filter unit 300 can be firmly clamped in the clamping assembly 410, which is conducive to improving the stability and reliability of the clamping assembly 410 clamping the filter unit 300.

[0057] Of course, the locking assembly 430 can also be other structures, such as a snap-on locking structure, a pin hole stud locking structure, etc., and the present application does not impose any restrictions on this, as long as it can achieve locking and unlocking of the output end of the clamping mechanism on the cover plate 200.

[0058] In a specific embodiment, Figure 4 As shown, the card slot 431 is arranged on the first slider 422. A side surface of the cover plate 200 away from the accommodating chamber is provided with a slide slot 201 extending from the upper clamping plate 412 to the lower clamping plate 413, and the first slider 422 is located in the slide slot 201. In this way, the slide slot 201 can guide the movement of the first slider 422. Further, a receiving groove 2011 is arranged on at least one side wall in the width direction of the slide slot 201, and at least part of the card block 432 is located in the receiving groove 2011. When the upper clamping plate 412 and the lower clamping plate 413 clamp the filter unit 300, the card block 432 is clamped in the card slot 431 of the first slider 422. Thus, the position of the first slider 422 is locked, so that the filter unit 300 can be firmly clamped in the clamping assembly 410, thereby facilitating the improvement of the stability and reliability of the clamping assembly 410 clamping the filter unit 300.

[0059] In some embodiments, Figure 4 As shown, the locking assembly 430 also includes a first elastic member 433, and the first elastic member 433 is arranged between the block 432 and the receiving groove 2011. In this way, when the upper clamping plate 412 and the lower clamping plate 413 clamp the filter unit 300, the block 432 is clamped in the slot 431. At this time, the first elastic member 433 can provide a certain reaction force to prevent the block 432 from easily detaching from the slot 431, which is beneficial to improve the reliability of the locking of the locking assembly 430. When unlocking is required, only an external force is needed to drive the block 432 to move toward the bottom of the receiving groove 2011 so that the block 432 is detached from the slot 431. In this way, the first slider 422 is in an unlocked state. At this time, the clamping assembly 410 can be driven to release the filter unit 300 by driving the first slider 422. Optionally, in order to improve the convenience of moving the block 432, as shown in FIG. Figure 3 As shown, the locking assembly 430 may further include a paddle 434 connected to the block 432. Optionally, the first elastic member 433 may be a spring, a rubber body, or the like.

[0060] In some embodiments, Figure 2As shown, the driving assembly 420 also includes a second elastic member 423, which is sleeved on the slide bar 411 and located between the upper clamping plate 412 and the lower clamping plate 413. The second elastic member 423 can realize the reset action of the upper clamping plate 412 and the lower clamping plate 413. Specifically, when the first slider 422 drives the upper clamping plate 412 and the lower clamping plate 413 to clamp the filter unit 300, and the first slider 422 is locked by the locking assembly 430, the second elastic member 423 will generate a reaction force due to its own compression. When the first slider 422 is unlocked, it is not necessary to drive the first slider 422 by an external force, but can directly drive the upper clamping plate 412 and the lower clamping plate 413 to move in the opposite direction with the help of the reaction force of the second elastic member 423, so that the upper clamping plate 412 and the lower clamping plate 413 release the filter unit 300 and return to the initial state. Thus, the intervention of external force can be reduced, which is conducive to improving the convenience of the driving assembly 420 driving the upper clamping plate 412 and the lower clamping plate 413. Optionally, the second elastic member 423 can be a spring, a rubber body, etc.

[0061] In some embodiments, Figure 5 Shown and referenced Figure 3 The clamping assembly 410 includes an upper clamping plate 412 and a lower clamping plate 413, one end of the filter unit 300 is located between the upper clamping plate 412 and the lower clamping plate 413, the driving assembly 420 includes a first electric push rod 424, a second electric push rod 425 and a switch (not shown in the figure) electrically connected to the first electric push rod 424 and the second electric push rod 425, the first electric push rod 424 and the second electric push rod 425 are both connected to a side surface of the cover plate 200 close to the accommodating cavity, the output end of the first electric push rod 424 is connected to the upper clamping plate 412, the output end of the second electric push rod 425 is connected to the lower clamping plate 413, and the switch is arranged on a side surface of the cover plate 200 away from the accommodating cavity.

[0062] This embodiment proposes another structure of the clamping assembly 410 and the driving assembly 420 of the clamping mechanism 400. In this embodiment, by pressing the switch, the first electric push rod 424 can be driven to extend or contract, and the second electric push rod 425 can be driven to extend or contract, thereby driving the upper clamping plate 412 and the lower clamping plate 413 to move closer to or away from each other, so as to achieve the clamping or loosening of the filter unit 300. In this way, it is beneficial to improve the convenience of replacing the filter unit 300 while improving the intelligence and automation of the clamping mechanism 400. It is easy to understand that the electric push rod can also be replaced by a common driving structure such as a cylinder, an electric cylinder, a hydraulic cylinder, etc., and this application does not limit this.
