Description

Technical Field

[0001] The invention belongs to the field of filters, and in particular relates to a housing component and an air filter element structure for a vehicle. Background Art

[0002] The air filter is an important part of the engine, mainly composed of two parts: the filter element and the housing. The filter element is the core component of the air filter. During the operation of the engine, a large amount of air will be inhaled. If the air is not filtered, the suspended dust particles in the air will be inhaled into the cylinder, which will accelerate the wear of the piston group and the cylinder. The main function of the air filter is to block and absorb impurities in the air through the filter medium to ensure that the air quality entering the mechanical equipment or engine is in the best state.

[0003] However, the existing technology has shortcomings. The existing air filter simply filters the air through the internal filter element, which has poor filtering effect and low filtering efficiency.

[0004] The present application proposes a vehicle air filter housing component and an air filter element structure to improve the above-mentioned defects. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a vehicle air filter housing component and an air filter element structure that can efficiently filter incoming gas.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A vehicle air filter housing component and air filter element structure includes an upper housing, a lower housing, a mounting bracket, an air inlet pipe, an air outlet pipe, and a filter device. The bottom of the upper housing is screwed together with the lower housing via a thread, and a mounting bracket is fixed to the side wall of the upper housing. One side of the upper housing is provided with an air inlet pipe connected to the air inlet of the automobile engine, and the top of the upper housing is provided with an air outlet pipe. A filter device is built into the interior of the upper housing.

[0008] In a specific embodiment, the filter device includes an outer filter housing, blades and a filter core structure. The outer annular array of the outer filter housing has a plurality of blades, and the inner part of the outer filter housing is equipped with a filter core structure capable of filtering air.

[0009] In a specific possible implementation scheme, the filter element structure includes a driving component, a driven component, a filter element and a motor. The bottom of the driving component is connected to the output end of the motor. The motor is installed on the lower shell. One side of the driving component is equipped with a driven component, and the filter element is installed on the driven component.

[0010] In a specific feasible implementation scheme, the drive assembly includes a mounting frame, a connecting shaft, a gear, a pin hole, a connecting frame, a sleeve, an L-plate and a paddle. Connecting shafts are installed at the centers of the upper and lower ends of the mounting frame. The connecting shaft at the top rotates with the gear. A connecting frame is fixed on one side of the mounting frame, and a sleeve is installed on the connecting frame. Two groups of L-plates are fixed on the other side of the mounting frame. The two groups of L-plates are symmetrically arranged and are both equipped with paddles.

[0011] In a specific possible implementation manner, a fixing column is provided on the gear, and the top end of the fixing column is connected to the inner wall of the outer filter housing.

[0012] In a specific feasible implementation scheme, the driven assembly includes a main shaft, a driving gear, a first bevel gear, a second bevel gear and a rotating shaft. The main shaft is installed in a sleeve and rotates with the sleeve. The driving gear is fixed on the top of the main shaft, and the first bevel gear is installed on the bottom of the main shaft. The second bevel gear is meshed with one side of the first bevel gear, and the center of the second bevel gear is connected to the rotating shaft. The head and tail ends of the rotating shaft are located in the mounting frame and rotate with the pin holes on the mounting frame.

[0013] In a specific possible implementation scheme, the outer filter shell includes a mounting groove, a vibrating member and a pre-filter screen. There are several mounting grooves in a circular array on the cylindrical wall of the outer filter shell. Several of the mounting grooves are equipped with vibrating members on one side close to the inside of the filter shell, and several of the mounting grooves are fixed with pre-filter screens.

[0014] In a specific possible implementation scheme, the vibrating member includes a mounting bar, an elastic column, a brush and a spring. The mounting bar is provided with two groups above and below. Several elastic columns are installed between the two groups of mounting bars. A brush is fixed on one side of several elastic columns. A spring is installed between each two adjacent groups of elastic columns.

[0015] In a specific possible implementation manner, the distances between the plurality of elastic columns are the same, and the plurality of elastic columns are all made of soft rubber material, are elastic, and are in contact with the paddles on the mounting frame.

[0016] In a specific embodiment, the brush is of a Y-shaped structure, and the contact area with the pre-filter can be increased by the forked brush heads at both ends.

[0017] In a specific possible implementation scheme, the two ends of the spring are connected to two adjacent groups of elastic columns, which can connect the multiple elastic columns to form a whole, so that the multiple elastic columns are linked.

[0018] According to the technical solution proposed above, the vehicle air filter housing component and air filter element structure of the present invention have the following beneficial effects:

[0019] (1) The present invention provides a threaded connection between the upper shell and the lower shell, so that the upper shell and the lower shell can be disassembled, which facilitates the maintenance and replacement of the internal filter device and improves the replacement efficiency.

[0020] (2) The present invention provides a pre-filter screen on the outer filter housing inside the filter. The pre-filter screen is made of metal mesh or nylon, which can intercept larger particles (such as dust and hair) in the incoming gas and protect the internal filter element from being blocked prematurely.

[0021] (3) The present invention provides a vibrating member on the outer filter shell, and uses the elastic column to contact the paddle, and the paddle moves the elastic column to vibrate left and right, and drives the brush to shake together, so as to clean the dust adhering to the filter net, thereby ensuring the filtering and intercepting effect of the pre-filter net. The spring on the elastic column connects the multiple elastic columns into a whole, so that the multiple elastic columns are linked, increasing the vibration effect of the elastic column, making the vibration frequency of the elastic column faster, and improving the cleaning effect of the brush on the filter net.

[0022] (4) The present invention drives the connecting shaft and the mounting frame to rotate by means of a driving motor. The rotation of the mounting frame drives the connecting frame on one side to rotate synchronously. The connecting frame drives the driving gear located inside it to make a circular motion around the gear. At this time, the main shaft drives the first bevel gear at the bottom to rotate synchronously. The first bevel gear is engaged with the second bevel gear, which drives the second bevel gear and the filter element to rotate together, so that the filter element can increase the contact area and contact efficiency with the air, thereby improving the filtering effect on the gas.

The interior of the upper housing 1 is equipped with a filter device 6 for filtering the incoming air.

[0037] See also Figure 1 The threaded connection between the upper shell 1 and the lower shell 2 enables the upper shell 1 and the lower shell 2 to be disassembled, making it easy to maintain and replace the internal filtering device 6.

[0038] See also Figure 2The filter device 6 includes an outer filter shell 61, blades 62 and a filter element structure 63. The outer annular array of the outer filter shell 61 has a plurality of blades 62, which can guide the incoming gas. The interior of the outer filter shell 61 is equipped with a filter element structure 63 that can filter the air.

[0039] See also Figure 3 The filter element structure 63 includes a driving component 631, a driven component 632, a filter element 633 and a motor 634. The bottom of the driving component 631 is connected to the output end of the motor 634. The motor 634 is installed on the lower shell 2 and is electrically connected to the external controller. One side of the driving component 631 is equipped with a driven component 632, and the driven component 632 is equipped with a filter element 633 that can filter the gas.

[0040] See also Figure 4 The driving assembly 631 includes a mounting frame 11, a connecting shaft 12, a gear 13, a pin hole 14, a connecting frame 15, a sleeve 16, an L-plate 17 and a paddle 18. Connecting shafts 12 are installed at the centers of the upper and lower ends of the mounting frame 11. The bottom connecting shaft 12 is connected to the motor 634 and can drive the mounting frame 11 to rotate through the motor 634. The top connecting shaft 12 rotates in coordination with the gear 13. A connecting frame 15 is fixed to one side of the mounting frame 11, and a sleeve 16 is installed on the connecting frame 15. Two groups of L-plates 17 are fixed to the other side of the mounting frame 11. The two groups of L-plates 17 are symmetrically arranged and are both equipped with paddles 18.

[0041] See also Figure 3 The gear 13 is provided with a fixing column 131, the top of which is connected to the inner wall of the outer filter shell 61, which can fix the gear 13 so that the gear 13 will not rotate when the mounting frame 11 rotates.

[0042] See also Figure 5 The driven assembly 632 includes a main shaft 21, a driving gear 22, a first bevel gear 23, a second bevel gear 24 and a rotating shaft 25. The main shaft 21 is installed in the sleeve 16 and rotates with the sleeve 16. The top of the main shaft 21 is fixed with a driving gear 22 that meshes with the gear 13. The bottom of the main shaft 21 is installed with a first bevel gear 23. One side of the first bevel gear 23 is meshed with the second bevel gear 24. The center of the second bevel gear 24 is connected to the rotating shaft 25.

The filter element 633 is installed on the rotating shaft 25 and will rotate synchronously with the rotating shaft 25.

[0043] See also Figure 3-Figure 5The motor 634 drives the mounting frame 11 connected thereto to rotate. The rotation of the mounting frame 11 drives the connecting frame 15 on one side to rotate synchronously. The connecting frame 15 drives the driving gear 22 located inside it to perform circular motion around the gear 13, and drives the first bevel gear 23 at the bottom thereof to rotate. Through the engagement of the first bevel gear 23 with the second bevel gear 24, the second bevel gear 24 and the filter element 633 connected thereto are driven to rotate together on the rotating shaft 25, so that the filter element 633 can increase the contact area and contact efficiency with the air, thereby improving the filtering effect of the gas.

[0044] Example 2: Please refer to Figure 6-Figure 9 , the specific embodiments of the present invention are as follows:

[0045] See also Figure 6 The outer filter shell 61 includes a mounting groove 611, a vibrating member 612 and a pre-filter 613. There are several mounting grooves 611 in a circular array on the cylinder wall of the outer filter shell 61. The vibrating member 612 is installed on one side of the several mounting grooves 611 close to the inside of the filter shell, and the pre-filter 613 is fixed on the several mounting grooves 611.

[0046] See also Figure 6 The pre-filter 613 is made of metal mesh or nylon, which can intercept larger particles such as dust and hair in the incoming gas, and can protect the internal filter element 633 from being blocked prematurely.

[0047] See also Figure 7 The vibrating member 612 includes a mounting strip 31, an elastic column 32, a brush 33 and a spring 34. Two groups of mounting strips 31 are provided above and below. One side of the two groups of mounting strips 31 is fixed to the inner wall of the outer filter shell 61. Several elastic columns 32 are installed between the two groups of mounting strips 31. Brushes 33 are fixed on one side of the several elastic columns 32 close to the pre-filter 613. A spring 34 is installed between each two adjacent groups of elastic columns 32.

[0048] See also Figure 7 The distances between the elastic columns 32 are the same, and they are all made of soft rubber and are elastic. They are in contact with the paddle 18 on the mounting frame 11. When the paddle 18 rotates with the mounting frame 11, it will contact the elastic column 32, and the elastic column 32 will vibrate left and right.

[0049] See also Figure 7 The brush 33 has a Y-shaped structure, and the forked brush heads at both ends can increase the contact area with the pre-filter 613. When the elastic column 32 vibrates left and right, it will drive the brush 33 to vibrate together, cleaning the dust adhered to the filter, ensuring the filtering and interception effect of the pre-filter 613.

[0050] See also Figure 7-Figure 8The two ends of the spring 34 are connected to two adjacent groups of elastic columns 32, which can connect several elastic columns 32 to form a whole, so that several elastic columns 32 are linked. When one elastic column 32 vibrates, the vibration force will be transmitted to the adjacent elastic column 32 with the help of the spring 34, thereby increasing the vibration effect of the elastic column 32, and with the help of the elastic potential energy of the spring 34 itself, the vibration force can be increased, making the vibration frequency of the elastic column 32 faster, thereby improving the cleaning effect of the brush 33 on the filter.

[0051] Based on the above embodiment, the specific working principle is as follows:

[0052] When the vehicle air filter is in use, the engine's air intake draws in external air and enters the filter through the intake pipe 4. Inside the upper housing 1, the air is guided by the blades 62, allowing the air to fully contact the outer filter housing 61 and pass through the pre-filters 613 installed on the outer filter housing 61 to enter the internal filter element 633 for in-depth filtration.

[0053] The pre-filter 613 on the outer filter housing 61 is made of metal mesh or nylon, and intercepts larger dust and hair particles in the incoming gas. At the same time, the driving motor 634 drives the connecting shaft 12 and the mounting frame 11 to rotate. The rotation of the mounting frame 11 will drive the connecting frame 15 on one side to rotate synchronously. The connecting frame 15 will drive the driving gear 22 located inside it to make a circular motion around the gear 13. At this time, the main shaft 21 will drive the first bevel gear 23 at the bottom thereof to rotate synchronously. Through the engagement of the first bevel gear 23 with the second bevel gear 24, the second bevel gear 24 and the rotating shaft 25 connected thereto will be driven to rotate on the mounting frame 11, and the filter element 633 located on the rotating shaft 25 will be driven to rotate together, so that the filter element 633 can increase the contact area and contact efficiency with the air, thereby improving the filtering effect of the gas.

[0054] When the mounting frame 11 is rotating, the paddle 18 on the mounting frame 11 will contact the elastic column 32 on the vibrating member 612, and the paddle 18 will move the elastic column 32 to vibrate left and right, and drive the brush 33 to vibrate together, so as to clean the dust adhering to the filter net, thereby ensuring the filtering and intercepting effect of the pre-filter 613, and the spring 34 on the elastic column 32 connects the plurality of elastic columns 32 into a whole, so that the plurality of elastic columns 32 are linked, thereby increasing the vibration effect of the elastic column 32, making the vibration frequency of the elastic column 32 faster, and improving the cleaning effect of the brush 33 on the filter net. After the gas is filtered in the filter element 633, it will be discharged from the outlet pipe 5 at the top of the shell.
