Description

Technical Field

[0001] The utility model relates to the technical field of mechanical design and manufacturing, in particular to a vehicle air-conditioning filter which is easy to replace. Background Art

[0002] As people's requirements for the quality of the in-car environment continue to increase, the technology of automotive air-conditioning filters is also gradually improving. In the early days, automotive air-conditioning systems mainly focused on temperature regulation and paid less attention to air filtration. However, in recent years, due to the intensification of environmental pollution, the amount of pollutants such as dust, pollen, harmful gases and microorganisms in the air has increased. People in the car are in a relatively closed space for a long time and are vulnerable to these pollutants. In order to improve the air quality in the car, automotive air-conditioning filter technology came into being and continued to develop. From the initial simple fiber filter, which can only filter larger particles of dust, to the current use of a combination of filter materials, such as activated carbon and high-efficiency filter paper, it can effectively filter a variety of pollutants.

[0003] In response to the above problems, the existing patent provides a solution. The existing easy-to-replace automotive air-conditioning filter uses a snap-on structure to connect the filter to the card shell. However, during long-term use, due to factors such as vehicle vibration and temperature changes, the card slot is prone to loosening. Once loose, it may cause gas leakage, affecting the filtering effect and the normal operation of the air-conditioning system. Moreover, when the filter is replaced, the upper shell and the lower shell need to be snapped and fixed. When the upper shell and the lower shell are not aligned and snapped together, a gap will be created, causing some air to bypass the filter and enter the car directly through the gap when the air-conditioning system is running, affecting its filtering effect.

[0004] Therefore, a vehicle air-conditioning filter that is easy to replace is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide a vehicle air-conditioning filter that is easy to replace, which can solve the problem that the existing vehicle air-conditioning filter that is easy to replace uses a snap-fit ​​structure to connect the filter and the card shell, but during long-term use, due to factors such as vehicle vibration and temperature changes, the card slot is prone to loosening. Once loosened, it may cause gas leakage, affecting the filtering effect and the normal operation of the air-conditioning system. Moreover, when the filter is replaced, the upper shell and the lower shell need to be snap-fitted and fixed. When the upper shell and the lower shell are not aligned and snap-fitted, a gap will be generated, causing some air to bypass the filter and enter the vehicle directly from the gap when the air-conditioning system is running, affecting its filtering effect.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figure 1-6 , this utility model provides a technical solution:

[0029] A vehicle air conditioning filter that is easily replaceable comprises a housing 1, an upper shell 2 being snap-fitted to the top of the housing 1, a fixing seat 3 being slidably connected to the front side of the housing 1, a placement plate 4 being fixedly connected to the rear side of the fixing seat 3, an air conditioning filter body 7 being disposed within the placement plate 4, fixing components 5 being disposed on both sides of the air conditioning filter body 7, and an auxiliary component 6 being disposed on the outer side of the placement plate 4;

[0030] The fixing assembly 5 is bolted to the fixing blocks 501 on both sides of the air conditioning filter body 7. A fixing groove 502 is provided inside the fixing block 501. A fixing rod 503 is slidably connected inside the fixing groove 502. A placement groove 504 is provided inside the placement plate 4. A return spring 505 is fixedly connected inside the placement groove 504. An adjusting block 506 is fixedly connected to the inner side of the return spring 505. An adjusting seat 507 is fixedly connected to the inner side of the fixing rod 503. The adjusting seat 507 is snap-fitted to the adjusting block 506.

[0031] In this embodiment, the fixing rod 503 on the outside of the fixing block 501 slides toward the inside of the fixing block 501, and then the adjustment seat 507 fixed on the inside of the fixing rod 503 moves to the bottom of the adjustment block 506. Due to the effect of the inclined surface of the adjustment seat 507, the adjustment seat 507 then generates an extrusion pressure on the adjustment block 506, and then the adjustment block 506 squeezes the return spring 505. Then the adjustment block 506 slides inside the placement groove 504, and at the same time, the elastic force of the return spring 505 limits the adjustment block 506 and the adjustment seat 507 to engage with each other, so as to fix the fixing block. 501 is fixed to the placement plate 4. When disassembly is required, the fixing rod 503 is moved outward, and then the fixing rod 503 moves while driving the limiting circular plate 11 to move outward, and then the limiting circular plate 11 squeezes the adjusting spring 10, and then the fixing rod 503 drives the adjusting seat 507 to move to release the clamping of the adjusting seat 507 and the adjusting block 506. When the fixing rod 503 is released, the return spring 505 drives the limiting circular plate 11 and the fixing rod 503 to move, and then the fixing rod 503 drives the adjusting seat 507 to move to re-clamp and fix the adjusting seat 507.

[0032] Specifically, such as Figure 3As shown, the auxiliary component 6 includes a limit block 601 fixedly connected to the top of the housing 1 , and a rotating rod 602 is threadedly connected to the outer side of the limit block 601 .

[0033] Specifically, such as Figure 3 As shown, a clamping block 603 is fixedly connected to the inner side of the rotating rod 602 , and limiting grooves 604 are provided on both sides of the fixing seat 3 .

[0034] Specifically, such as Figure 3 As shown, the interior of the limiting groove 604 is fixedly connected to the limiting frame 605 , the interior of the limiting frame 605 is slidably connected to the auxiliary block 606 , and the clamping block 603 is clamped with the auxiliary block 606 .

[0035] In this embodiment: by rotating the rotating rod 602, since the rotating rod 602 and the limit block 601 are threadedly connected, the rotating rod 602 drives the clamping block 603 to move when it rotates, and then the clamping block 603 moves inside the limit frame 605 until the clamping block 603 contacts the auxiliary block 606. Due to the inclined surface of the clamping block 603, outward pressure is generated on the auxiliary block 606. As the clamping block 603 moves, the auxiliary block 606 slides inside the limit frame 605 until it is clamped with the limit plate 9 inside the limit groove 604. Then the limit plate 9 generates inward pressure on the limit spring 8 fixed on the inside, causing the limit spring 8 to contract. The limit plate 9 is clamped and fixed to the auxiliary plate under the pressure of the spring inside the limit spring 8 and the outside of the auxiliary block 606.

[0036] Specifically, such as Figure 3 As shown, the interior of the limiting groove 604 is fixedly connected to the limiting spring 8 , the inner side of the limiting spring 8 is fixedly connected to the limiting plate 9 , and the inner side of the limiting plate 9 is engaged with the outer side of the auxiliary block 606 .

[0037] Specifically, such as Figure 2 As shown, the interior of the fixing groove 502 is fixedly connected to the adjusting spring 10 , and the outer side of the fixing rod 503 is fixedly connected to the limiting circular plate 11 .

[0038] When the auxiliary block 606 contacts the limit plate 9, the auxiliary block 606 that continues to move will produce an inward thrust on the limit plate 9, causing the limit plate 9 to move inward. The limit spring 8 connected to the inner side of the limit plate 9 is compressed as the limit plate 9 moves. At this time, the auxiliary block 606 is tightly engaged with the limit plate 9 under the combined action of the limit plate 9 and the pressure of its own outer side. The elastic force generated by the compression of the limit spring 8 is outward. This elastic force acts on the limit plate 9, while the outer side of the auxiliary block 606 is pressed inward by the inclined surface of the card block 603. The two forces in opposite directions act together on the contact surface of the auxiliary block 606 and the limit plate 9, thereby increasing the friction between the auxiliary block 606 and the limit plate 9, thereby making the fixing degree of the card block 603 and the auxiliary plate more stable. The elastic force of the spring 8 also prevents the auxiliary block 606 from easily disengaging from the clamping state with the limit plate 9 when slightly disturbed by the outside world, further enhancing the stability of the entire fixed structure. By setting the adjusting spring 10 and the limiting circular plate 11, when the fixing rod 503 is moved, the limiting circular plate 11 is also driven to move, and then the limiting circular plate 11 squeezes the adjusting spring 10 to make it contract. When the disassembly operation of the air conditioning filter body 7 is completed, the fixing rod 503 is released. At this time, since the previously compressed adjusting spring 10 has elastic potential energy to restore its original state, under the action of the elastic force, the adjusting spring 10 begins to stretch. When the adjusting spring 10 stretches, it pushes the limiting circular plate 11 to move inward, and the limiting circular plate 11 then drives the fixing rod 503 to move inward. During the process of the fixing rod 503 moving inward, the adjustment seat 507 inside it will return to the position below the adjusting block 506.

[0039] Specifically, such as Figure 4 As shown, a groove 12 is formed on the front side of the fixing seat 3 , and a pull plate 13 is fixedly connected to the interior of the groove 12 .

[0040] Specifically, such as Figure 4 、 Figure 5 As shown, the interior of the placement plate 4 is provided with a sealing sleeve 14 , and the sealing sleeve 14 is embedded in the outer side of the air conditioning filter body 7 .

[0041] In this embodiment: by providing the groove 12 and the pull plate 13, the groove 12 provides a stable installation base for the pull plate 13, and the pull plate 13 provides a convenient force application location for the operator. When the fixing seat 3 needs to be moved, the operator can hold the pull plate 13 with his hand and put his fingers into the space formed by the pull plate 13 and the groove 12 to effectively transfer the external force applied by the operator to the fixing seat 3. By providing the sealing sleeve 14, these potential air channels can be effectively filled to ensure that all air entering the air-conditioning system must pass through the filter material of the air-conditioning filter body 7 to prevent unfiltered air from entering the vehicle through the gap between the air-conditioning filter body 7 and the placement plate 4.

[0042] Specifically, such as Figure 5 As shown, a sliding block 15 is fixedly connected to the interior of the upper shell 2, and a sliding groove 16 is provided at the bottom of the placement plate 4, and the sliding block 15 is slidably connected to the sliding groove 16.

[0043] Specifically, such as Figure 2 、 Figure 6 As shown, an auxiliary groove 17 is formed at the bottom of the placement plate 4 , and a rubber pad 18 is bonded inside the auxiliary groove 17 .

[0044] In this embodiment: by providing a sliding block 15 and a slide groove 16, when the placement plate 4 is installed, the sliding block 15 slides along the slide groove 16 and can only move according to the trajectory of the slide groove 16, which ensures that the placement plate 4 can accurately reach the predetermined position every time, so that the relative positions of the air conditioning filter body 7 and the shell 1 and the upper shell 2 are consistent. By providing an auxiliary groove 17 and a rubber pad 18, the vehicle will continuously generate vibrations during driving, and these vibrations may be transmitted to the air conditioning filter component. The rubber pad 18 has good elasticity and buffering properties. When the placement plate 4 is vibrated, the rubber pad 18 in the auxiliary groove 17 can absorb and disperse the vibration energy to protect the air conditioning filter body 7.

[0045] Working principle: When using the easily replaceable vehicle air conditioning filter, first bolt the air conditioning filter body 7 to the fixed block 501, then slide the fixing rod 503 on the outside of the fixed block 501 toward the inside of the fixed block 501, then move the adjustment seat 507 fixed on the inside of the fixing rod 503 to the bottom of the adjustment block 506, due to the action of the inclined surface of the adjustment seat 507, then the adjustment seat 507 generates squeezing pressure on the adjustment block 506, then the adjustment block 506 squeezes the return spring 505, then the adjustment block 506 slides inside the placement groove 504, and at the same time, the elastic force of the return spring 505 limits the adjustment block 506 and the adjustment seat 507 to be clamped, so as to align the fixed block 501 and the placement plate 4. When the filter element 7 is disassembled and replaced, the rotating rod 602 is rotated. Since the rotating rod 602 is threadedly connected to the limiting block 601, the rotating rod 602 rotates. When the block 603 is in the closed position, the block 603 is moved, and then the block 603 moves inside the limit frame 605 until the block 603 contacts the auxiliary block 606. Due to the tilt of the block 603, the auxiliary block 606 generates outward pressure. As the block 603 moves, the auxiliary block 606 slides inside the limit frame 605 until it is engaged with the limit plate 9 inside the limit groove 604. Then the limit plate 9 generates inward pressure on the limit spring 8 fixed on the inside, causing the limit spring 8 to contract. The limit plate 9 is fixed to the auxiliary plate by the spring inside the limit spring 8 and the pressure outside the auxiliary block 606. When the air conditioner filter needs to be disassembled, the fixation of the rotating rod 602 and the fixing seat 3 is released, and then the filter is removed by Pull the pull plate 13, then slide the placement plate 4 on the top of the sliding block 15, and then take out the fixing seat 3 and the placement plate 4 from the inside of the upper shell 2 and the shell 1, so as to solve the existing problem that the vehicle air-conditioning filter that is easy to replace is connected to the card shell through a snap structure, but during long-term use, due to factors such as vehicle vibration and temperature changes, the card slot is prone to loosening. Once loosened, it may cause gas leakage, affecting the filtering effect and the normal operation of the air-conditioning system, and when the filter is replaced, the upper shell and the lower shell need to be snapped and fixed. When the upper shell and the lower shell are not aligned and snapped together, a gap will be generated, causing some air to bypass the filter and enter the car directly from the gap when the air-conditioning system is running, affecting its filtering effect.

[0046] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
