Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, and in particular relates to an adjustable filter mounting bracket. Background Technology

[0002] Automotive filters, also known as car air filters, are filters used to filter impurities or gases. Common automotive filters include air filters, cabin air filters, oil filters, and fuel filters. Each type of filter filters different types of impurities, but they all primarily filter impurities from air or liquids. Automotive filters offer high filtration performance (cleaning effect); long lifespan (large capture capacity); high durability and vibration resistance, preventing dust leakage; water resistance, preventing air blockage; and easy and lightweight installation and removal. After prolonged use, the filtration performance of automotive filters deteriorates, requiring disassembly and replacement. Traditional automotive filters are mostly fixed directly in the filter housing with bolts. Replacement requires removing a large number of bolts, which is cumbersome and time-consuming, resulting in poor practicality. Due to manufacturing errors in size, automotive filters are difficult to fit perfectly into the housing. During vehicle operation, the lack of necessary cushioning and vibration damping devices causes the filter to shake continuously within the housing, leading to misalignment, affecting filtration efficiency, and the continuous vibration can also shorten the filter's lifespan. In response, patent document CN215321906U discloses an automotive filter mounting bracket, including a bracket frame. A support rib is located in the middle of the inner side of the bracket frame, and multiple evenly distributed top blocks are arranged on the support rib. Two sets of four clamping mechanisms are symmetrically arranged at the left and right ends of the bracket frame. Each clamping mechanism includes a mounting cylinder, the right end of which is fixedly connected to the outside of the bracket frame. An operating cavity is provided inside the mounting cylinder, and a hexagonal sliding cylinder is located at the right end of the operating cavity. A screw is rotatably connected inside the operating cavity, and a hexagonal rod is threaded to the left end of the screw. This technology, by setting up a clamping mechanism, utilizes a pressure pad made of silicone on the outside of the hexagonal rod, which increases friction with the inner wall of the mounting box, making the bracket frame more securely fixed and preventing scratches on the inner wall of the mounting box. It eliminates the need for bolt connections, making disassembly and installation more convenient and enhancing the practicality of the device. In this patent document, the size of the bracket frame is fixed. Although the tensioning mechanism has a certain range of adjustment, the entire bracket cannot be adapted to mounting boxes or filters with large size differences, resulting in a limited range of application for the mounting bracket. Therefore, it is necessary to improve this mounting bracket. Utility Model Content

[0003] The purpose of this utility model is to address the aforementioned technical problems by providing an adjustable filter mounting bracket. In this bracket, both the frame structure and connecting components are adjustable, enabling it to adapt to various filters and mounting boxes of different widths, thereby significantly improving the product's versatility and applicability.

[0004] In view of this, the present invention provides an adjustable filter fixing bracket, comprising: The frame includes a fixed frame and a movable frame. The fixed frame and the movable frame together form a receiving space for the filter to be placed. The bottom of both the fixed frame and the movable frame is provided with a support plate to hold the filter. The distance between the fixed frame and the movable frame can be adjusted, thereby adjusting the width of the receiving space. Locking mechanism, which can lock or unlock the fixed frame and the movable frame in the current position; A clamping plate is installed on the frame, and the receiving space is located between the clamping plate and the tray. The clamping plate can cooperate with the tray to clamp the filter in the receiving space. Two sets of connecting components are respectively set on both sides of the frame. The two sets of connecting components can secure the frame in the mounting box. The distance between the two sets of connecting components varies with the width of the accommodating space.

[0005] In this technical solution, the distance between the fixed frame and the movable frame is adjustable, thereby flexibly adjusting the width of the accommodating space to accommodate filters of different widths. The locking mechanism prevents changes in the frame dimensions during use. The clamping plate cooperates with the tray to press and fix the filter placed in the accommodating space, preventing the filter from moving up and down during use. The distance between the two sets of connecting components can change synchronously with the width of the accommodating space, thereby ensuring that no matter what width the frame is adjusted to, the connecting components can be fastened to the appropriate position on the inner wall of the mounting box.

[0006] In the above technical solution, both the fixed frame and the movable frame are U-shaped. The side walls at both ends of the fixed frame are provided with limiting grooves. The side walls of the two limiting grooves are provided with multiple first threaded holes at intervals along the width change direction of the accommodating space. The movable frame is provided with sliding beams at both ends. The two sliding beams are slidably disposed in the two limiting grooves along the width change direction of the accommodating space. The two sliding beams are provided with multiple mounting through holes at intervals along the width change direction of the accommodating space. The locking element is a threaded fastener. The locking element cooperates with the mounting through holes and the first threaded holes to lock the fixed frame and the movable frame in the current position.

[0007] In the above technical solution, furthermore, mounting blocks are provided on the two opposite side walls of the frame, and the two mounting blocks are provided with second threaded holes. The clamping plate is U-shaped, and clamping screws are rotatably connected to both ends of the clamping plate. The two clamping screws are respectively threadedly connected to the two second threaded holes.

[0008] In the above technical solution, furthermore, mounting grooves are provided on the side walls of the frame and the two sets of connecting components that are opposite to each other. A set of sliding seats is slidably arranged in each of the two mounting grooves along the direction perpendicular to the width change of the accommodating space, and each set of connecting components is installed on a set of sliding seats.

[0009] In the above technical solution, each set of connecting components includes two connectors, the number of sliding seats is the same as the number of connectors, and each connector is mounted on a sliding seat.

[0010] In the above technical solution, the sliding seat is further provided with a third threaded hole, and a locking screw is threadedly connected to the third threaded hole. The threaded end of the locking screw can contact the bottom surface of the mounting groove.

[0011] In the above technical solution, the connecting component further includes a fixed cylinder, a connecting rod, a contact block, and a driving component. The fixed cylinder is mounted on the sliding seat, one end of the connecting rod is movably mounted on the fixed cylinder, the contact block is mounted on the other end of the connecting rod, and the driving component can adjust the position of the connecting rod on the fixed cylinder, thereby adjusting the distance between the contact block and the fixed cylinder. The contact block contacts the inner wall of the mounting box.

[0012] The beneficial effects of this utility model are: 1. Through the adjustable-width frame structure (fixed frame and movable frame) and sliding connection components, one bracket can be adapted to a variety of different sizes of filters and mounting boxes, solving the problem of poor versatility of traditional fixed-size brackets, realizing "one bracket for multiple uses", and greatly expanding the application range of the product.

[0013] 2. Inheriting the convenience of boltless fixing in existing technologies, the bracket can be quickly installed and disassembled by rotating the handwheel. Simultaneously, the adjustable feature ensures that the connecting components are always in the optimal tension position within the mounting box, providing uniform and reliable tightening force. Combined with the upper and lower clamping structure, it ensures that the filter will not loosen in vehicle vibration environments, improving the reliability of the fixation and driving safety.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In the description of this utility model, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items, and therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0024] This embodiment provides an adjustable filter fixing bracket, including a frame 1, a locking component 2, a pressing plate 3, and two sets of connecting components; Main body Frame 1 is the base of the entire support structure, generally made of high-strength, lightweight materials, preferably aluminum alloy profiles or high-strength engineering plastics (such as polyamide PA66, reinforced with glass fiber), for example... Figure 1 and Figure 2 As shown, the frame 1 consists of a fixed frame 101 and a movable frame 102. Both the fixed frame 101 and the movable frame 102 adopt a U-shaped structure, with their openings facing each other, together forming a square storage space. Please see Figure 3 On the upright sidewalls at both ends of the fixing frame 101, a limiting groove 1011 with an inward opening is machined. Multiple first threaded holes 1012 are machined at equal intervals along the length direction of the limiting groove 1011 (i.e., the left-right direction shown in the figure, which is also the direction of width variation of the accommodating space); please refer to... Figure 4 Both ends of the movable frame 102 are fixed with sliding beams 1021 that match the shape of the limiting slide groove 1011. The sliding beams 1021 can be precisely inserted into and slid in the limiting slide groove 1011. This design ensures that the movable frame 102 slides smoothly relative to the fixed frame 101 without shifting. On the sliding beams 1021, multiple mounting through holes 1022 are also provided along its length. The locking element 2 is preferably a hexagon socket head cap screw or a wing bolt. When the movable frame 102 slides relative to the fixed frame 101, adjusting the width of the accommodating space to match the size of the filter to be installed, the locking element 2 is passed through one of the mounting through holes 1022 on the sliding beam 1021 and screwed into a first threaded hole 1012 on the aligned fixed frame 101. By tightening the locking element 2, the fixed frame 101 and the movable frame 102 are securely locked together, forming a rigid frame 1 of fixed dimensions. Alternatively, multiple locking elements 2 can be used simultaneously to fasten one side of the frame 1. Figure 1 and Figure 2 The image shows a case where two locking elements 2 are used to fasten one side of the frame 1. Please see Figure 3 and Figure 4 On the inner bottom of the fixed frame 101 and the movable frame 102, a support plate 103 is integrally formed or fixed by a connector 4. The support plate 103 is used to support the bottom of the filter. The upper surface of the support plate 103 can be glued or molded with an elastic material, such as silicone or rubber pad, to provide cushioning and anti-slip properties. Please refer to [link / reference]. Figure 1 and Figure 2 After the width of the accommodating space is adjusted, the support plate 103 on the fixed frame 101 and the support plate 103 on the movable frame 102 can not intersect, so that the two support plates 103 can support the two sides of the bottom of the filter respectively.

[0025] Clamping part On the top outer side of the fixed frame 101 and / or the movable frame 102, there is a mounting block 301, and the upper surface of the mounting block 301 is machined with a second threaded hole. The clamping plate 3 is an inverted U-shaped plate with a width slightly smaller than that of the frame 1. The two ends of the clamping plate 3 are rotatably connected to clamping screws 302 through bearings or simple smooth through holes. The two clamping screws 302 respectively form threaded pairs with the second threaded holes on the two mounting blocks 301. When the filter needs to be inserted or removed, the two clamping screws 302 can be separated from the two second threaded holes, and the clamping plate 3 can be removed from the frame 1. After the filter is placed into the receiving space of the frame 1 and supported by the bottom plate 103, the clamping plate 3 and the two clamping screws 302 can be installed back and the two clamping screws 302 can be tightened. The clamping screws 302 move downward under the guidance of the second threaded holes, thereby pushing the entire clamping plate 3 downward. Finally, the bottom surface of the middle part of the clamping plate 3 is pressed against the top edge of the filter (or the top mounting flange). By adjusting the screwing depth of the two clamping screws 302, the clamping force can be evenly distributed, and the filter can be reliably fixed in the vertical direction to prevent it from jumping up and down.

[0026] Connection component part The connecting assembly is used to secure the entire bracket inside the vehicle's mounting box; please refer to [link / reference]. Figure 1 and Figure 2 On the outer side walls of the fixed frame 101 and the movable frame 102, there is a mounting groove 5 extending longitudinally along the support. Each set of connecting components includes two connectors 4, each connector 4 being mounted in a mounting groove 5 via a sliding seat 6. The sliding seat 6 can slide back and forth within the mounting groove 5. Please refer to [link / reference]. Figure 5 The sliding seat 6 has a third threaded hole 601 machined on it, which penetrates the side wall of the sliding seat 6. Please refer to [link / reference]. Figure 1 and Figure 2 The third threaded hole 601 is equipped with a locking screw 602. When the sliding seat 6 slides to the appropriate position, tighten the locking screw 602 so that the threaded end of the locking screw 602 is tightly against the bottom surface of the mounting groove 5, and it can be fixed in the mounting groove 5. Please see Figure 5 and Figure 6 Each connector 4 includes: a fixed cylinder 401, a connecting rod 402, a contact block 403, and a driving component 404. The fixed cylinder 401 is fixedly mounted on the sliding seat 6. One end of the fixed cylinder 401 has a mounting hole, and the side wall of the fixed cylinder 401 has a mounting groove communicating with the mounting hole. One end of the connecting rod 402 passes through the mounting hole and extends into the fixed cylinder 401. The connecting rod 402 can slide axially within the mounting hole. For example, the outline of the mounting hole is a regular polygon, and the outer outline of the connecting rod 402 is also a regular polygon. The end of the connecting rod 402 that enters the fixed cylinder 401 has a fourth threaded hole 4021. The contact block 403 is fixed to the other end of the connecting rod 402. The contact block 403 is preferably made of a soft material with a high coefficient of friction. The material is made of silicone; the drive component 404 includes a drive screw 4041 and a handwheel 4042. One end of the drive screw 4041 is rotatably connected to the mounting hole, and the other end of the drive screw 4041 is threadedly engaged with the fourth threaded hole 4021 on the connecting rod 402. The handwheel 4042 is installed in the mounting groove and is coaxially fixedly connected to the drive screw 4041. The operator can contact the handwheel 4042 from the outside of the fixed cylinder 401 through the mounting groove and apply force to the handwheel 4042. Rotating the handwheel 4042 will drive the connecting rod 402 to extend or retract the contact block 403.

[0027] Working principle and process: Preliminary adjustment: First, slide the movable frame 102 according to the width of the filter to be installed so that the width of the accommodating space in the frame 1 matches the filter; then select the aligned mounting through hole 1022 and the first threaded hole 1012, and lock the frame 1 with the locking piece 2; Position pre-adjustment: Place the frame 1 (along with the filter) into the car's mounting box. According to the width and depth of the mounting box, slide the sliding seats 6 of each connector 4 back and forth so that the four contact blocks 403 are roughly aligned with the appropriate position on the side wall of the mounting box. Then, lock the sliding seats 6 in the current position by locking screw 602. Frame 1 fixed: Rotate the four handwheels 4042 in sequence to drive the connecting rod 402 to extend, so that the silicone contact block 403 presses tightly against the inner wall of the mounting box. Because the material of the contact block 403 is soft, it can provide huge friction to prevent the bracket from moving, and will not scratch the surface of the mounting box. The uniform tension of the four support points ensures the stability of the bracket. Press the filter: Tighten the pressing screws 302 at both ends of the pressing plate 3 to press the filter onto the support plate 103; Disassembly: When the filter needs to be replaced, simply reverse the steps above. The entire process can be completed using only a 4042 handwheel and a wrench (or an Allen key), making it easy to operate.

[0028] The embodiments of the present invention have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
