Description

Technical Field

[0001] This utility model relates to the field of air filter support technology, specifically an air filter support structure. Background Technology

[0002] An air filter is a device used to filter impurities in the air. It is widely used in many fields. Its core function is to remove pollutants such as particulate matter and harmful gases from the air through physical or chemical methods to ensure air quality and normal equipment operation. Air filters are also an important component of the automotive intake system. In the field of general internal combustion engines, air filters filter the air entering the internal combustion engine to prevent the engine from sucking in air containing impurities during operation, which would increase the chance of abrasion and damage.

[0003] On some large vehicles such as loaders and excavators, air filters are usually installed directly on the vehicle or on a bracket. However, the installation method is basically to fix and reinforce the air filter to the vehicle or bracket with bolts. Due to the large vibration of the vehicle, the air filter does not have a buffering effect and is easily damaged during the movement and vibration of the vehicle. At the same time, the installation and removal of the air filter is very troublesome. Utility Model Content

[0004] The purpose of this invention is to provide an air filter support structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an air filter support structure, including a base, an mounting plate fixedly installed at the bottom end of the base, a movable seat elastically installed on the mounting plate, a storage groove opened in the middle of the movable seat, an air filter being placed inside the storage groove, a vertical rod fixedly installed at one end of the base, a positioning plate symmetrically rotated at the top end of the vertical rod via a pivot pin, a pressure rod elastically installed in the middle of the positioning plate, and an installation assembly installed between the ends of the two positioning plates away from the vertical rod.

[0006] As a further preferred embodiment of this technical solution, the positioning plate has symmetrically provided first sliding holes in the middle, the pressure rod is slidably installed inside the first sliding holes, and a first spring is sleeved on the outer side of the top of the pressure rod. One end of the first spring is fixedly connected to the top of the pressure rod, and the other end of the first spring is fixedly connected to the upper surface of the positioning plate.

[0007] As a further preferred embodiment of this technical solution, the mounting plate has symmetrically provided second sliding holes inside, and the bottom of the movable seat has symmetrically fixedly installed movable rods. The movable rods are slidably connected to the second sliding holes. A second spring is sleeved on the outer side of the bottom end of the movable rod. One end of the second spring is fixedly connected to the bottom end of the movable rod, and the other end of the second spring is fixedly connected to the lower surface of the mounting plate.

[0008] As a further preferred embodiment of this technical solution, a connecting plate is fixedly installed between the bottom ends of two adjacent movable rods, and a shock absorber is fixedly installed on the lower surface of the mounting plate corresponding to the position of the connecting plate, with the movable end of the shock absorber fixedly connected to the middle of the connecting plate.

[0009] As a further preferred embodiment of this technical solution, the inner side of the positioning plate is provided with a slot for locking the air filter.

[0010] As a further preferred embodiment of this technical solution, the installation assembly includes a limiting hole, a positioning rod, a positioning hole, and a return spring. One of the positioning plates has a limiting hole at the end away from the upright, and the positioning rod is slidably installed inside the limiting hole. The other positioning plate has a positioning hole at the end away from the upright, and the positioning hole is slidably inserted into the positioning rod.

[0012] This utility model provides an air filter support structure, which has the following advantages:

[0013] (1) This utility model fixes the base to the position of the internal combustion engine on the vehicle with bolts, and then installs the bottom of the air filter in the storage groove of the movable seat. Rotating the two positioning plates, the bottom end of the pressure rod on the positioning plate is pressed against the recessed position of the top of the air filter. The top of the positioning rod is lifted, and the positioning rod is slid inside the limiting hole. At this time, the return spring is in the extended state, and the ends of the two positioning plates are brought close together to align the positioning rod with the positioning hole. Then, the lifting of the positioning rod is canceled. The positioning rod is pulled by the return spring and inserted into the positioning hole, which can fix the position between the two positioning plates. The air filter will be stuck between the slots on the two positioning plates for fixing the air filter. When removing the air filter, the top of the positioning rod is lifted and the positioning rod is slid out of the positioning hole, which can control the rotation of the two positioning plates and cancel the fixing of the positioning plate to the air filter. This makes it convenient for the installation and removal of the air filter.

[0014] (2) During the operation of the vehicle, when the vehicle is bumpy, the air filter will vibrate up and down. The movable seat will move up and down synchronously under the pull of the second spring on the movable rod. At the same time, the vibration of the air filter will act on the pressure rod that contacts the top of the air filter. The vibration of the air filter can be damped by the deformation of the second spring and the first spring, which is used to buffer and protect the air filter. At the same time, the movable seat indirectly connected to the shock absorber can be reset through the shock absorber, which is used to control the reset and fixation of the air filter.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figures 1 to 4As shown, in this embodiment, an air filter bracket structure includes a base 1. A mounting plate 2 is fixedly installed at the bottom of the base 1. A movable seat 3 is elastically installed on the mounting plate 2. A storage groove 4 is formed in the middle of the movable seat 3, and the air filter is placed inside the storage groove 4. A vertical rod 5 is fixedly installed at one end of the base 1. A positioning plate 6 is symmetrically mounted on the top of the vertical rod 5 via a pivot pin. A pressure rod 7 is elastically installed in the middle of the positioning plate 6. An installation assembly 8 is installed between the ends of the two positioning plates 6 away from the vertical rod 5. The base 1 is fixed to the vehicle at the position corresponding to the internal combustion engine using bolts. Then, the air filter is installed... The bottom of the air filter is installed inside the storage slot 4 of the movable seat 3. By rotating the two positioning plates 6, the bottom end of the pressure rod 7 on the positioning plate 6 is pressed against the recessed position at the top of the air filter. The position of the air filter between the two positioning plates 6 can be fixed by the installation component 8, which can be used to install and remove the air filter. When the vehicle is in motion and there are bumps, the air filter will vibrate up and down. The movable seat 3 will move up and down synchronously. At the same time, the vibration of the air filter will act on the pressure rod 7 that is in contact with the top of the air filter. The elastic movement of the pressure rod 7 can dampen the vibration of the air filter and provide buffer protection for the air filter.

[0022] like Figures 1 to 4 As shown, the positioning plate 6 has a first sliding hole 9 symmetrically opened in the middle. The pressure rod 7 is slidably installed inside the first sliding hole 9. A first spring 10 is sleeved on the outer side of the top of the pressure rod 7. One end of the first spring 10 is fixedly connected to the top of the pressure rod 7, and the other end of the first spring 10 is fixedly connected to the upper surface of the positioning plate 6.

[0023] When the air filter vibrates up and down, the vibration will act on the pressure rod 7 that is in contact with the top of the air filter. The vibration of the air filter can be damped by the deformation of the first spring 10, which is used to buffer and protect the top of the air filter.

[0024] like Figures 1 to 4 As shown, the mounting plate 2 has symmetrically opened second sliding holes 11 inside, and the bottom of the movable seat 3 is symmetrically fixedly installed with movable rods 12. The movable rods 12 are slidably connected to the second sliding holes 11. A second spring 13 is sleeved on the outer side of the bottom end of the movable rod 12. One end of the second spring 13 is fixedly connected to the bottom end of the movable rod 12, and the other end of the second spring 13 is fixedly connected to the lower surface of the mounting plate 2.

[0025] When the air filter vibrates up and down, the movable seat 3 will move up and down synchronously under the pull of the movable rod 12 by the second spring 13. The deformation of the second spring 13 can dampen the vibration at the bottom of the air filter, thus providing buffer protection for the air filter.

[0026] like Figures 1 to 4As shown, a connecting plate 14 is fixedly installed between the bottom ends of two adjacent movable rods 12, and a shock absorber 15 is fixedly installed on the lower surface of the mounting plate 2 at the position corresponding to the connecting plate 14. The movable end of the shock absorber 15 is fixedly connected to the middle part of the connecting plate 14.

[0027] The movable seat 3, which is indirectly connected to the shock absorber 15, can be reset via the shock absorber 15, thereby controlling the reset and fixation of the air filter.

[0028] like Figures 1 to 4 As shown, the inner side of the positioning plate 6 is provided with a slot 16 for locking the air filter.

[0029] The air filter can be positioned between the slots 16 on the two positioning plates 6 to prevent the air filter from shaking.

[0030] like Figures 1 to 4 As shown, the mounting assembly 8 includes a limiting hole 17, a positioning rod 18, a positioning hole 19, and a return spring 20. One of the positioning plates 6 has a limiting hole 17 at one end away from the upright 5, and the positioning rod 18 is slidably installed inside the limiting hole 17. The other positioning plate 6 has a positioning hole 19 at one end away from the upright 5, and the positioning hole 19 is slidably inserted into the positioning rod 18. A return spring 20 is sleeved on the outer side of the top end of the positioning rod 18. One end of the return spring 20 is fixedly connected to the top end of the positioning rod 18, and the other end of the return spring 20 is fixedly connected to the upper surface of the positioning plate 6.

[0031] Rotate the two positioning plates 6 to press the bottom of the pressure rod 7 on the positioning plate 6 against the recessed position at the top of the air filter. Lift the top of the positioning rod 18, causing it to slide inside the limiting hole 17. At this time, the return spring 20 is in a stretched state, bringing the ends of the two positioning plates 6 closer together to align the positioning rod 18 with the positioning hole 19. Then, release the lifting of the positioning rod 18. The pull of the positioning rod 18 by the return spring 20 will cause it to insert into the positioning hole 19, thus fixing the position between the two positioning plates 6. The air filter will be locked between the slots 16 on the two positioning plates 6 for fixing the air filter. When removing the air filter, lift the top of the positioning rod 18 to slide it out of the positioning hole 19, which will control the rotation of the two positioning plates 6 and release the fixing of the air filter by the positioning plates 6.

[0032] like Figures 1 to 4 As shown, rubber pads are installed inside the storage groove 4 and at the bottom of the pressure rod 7.

[0033] The rubber pads installed inside the storage slot 4 and at the bottom of the pressure rod 7 can protect the bottom and top of the air filter and prevent wear on the air filter.

[0034] This utility model provides an air filter support structure, the specific working principle of which is as follows:

[0035] When using the device, the base 1 is fixed to the vehicle at the position corresponding to the internal combustion engine using bolts. Then, the bottom of the air filter is installed inside the storage slot 4 of the movable seat 3. The two positioning plates 6 are rotated, pressing the bottom end of the pressure rod 7 on the positioning plate 6 against the recessed position at the top of the air filter. The top of the positioning rod 18 is lifted, causing the positioning rod 18 to slide inside the limiting hole 17. At this time, the return spring 20 is in a stretched state, bringing the ends of the two positioning plates 6 together to align the positioning rod 18 with the positioning hole 19. Then, the upper part is removed. Lifting the positioning rod 18 causes the return spring 20 to pull the positioning rod 18, which in turn drives the positioning rod 18 into the positioning hole 19, thus fixing the position between the two positioning plates 6. The air filter will be locked between the slots 16 on the two positioning plates 6 for fixing the air filter. When removing the air filter, lifting the top of the positioning rod 18 will slide the positioning rod 18 out of the positioning hole 19, which can control the rotation of the two positioning plates 6 and remove the fixing of the positioning plates 6 to the air filter, making it convenient for the installation and removal of the air filter.

[0036] During vehicle operation, when the vehicle experiences bumps, the air filter will vibrate up and down. The movable seat 3 will move up and down synchronously under the pull of the movable rod 12 by the second spring 13. At the same time, the vibration of the air filter will act on the pressure rod 7 that contacts the top of the air filter. The vibration of the air filter can be damped by the deformation of the second spring 13 and the first spring 10, which is used to buffer and protect the air filter. Meanwhile, the movable seat 3, which is indirectly connected to the shock absorber 15, can be reset through the shock absorber 15, which is used to control the reset and fixation of the air filter.
