Description

Technical Field

[0001] This application relates to the field of automotive radiator side panel technology, and more specifically, to an automotive radiator side panel structure. Background Technology

[0002] The side panel of a car radiator is a key frame component of the car radiator. It usually includes the side panel body and two side fixing plates. Its core function is to provide support and fixation for the internal structure such as the radiator core, maintain the overall shape stability of the radiator, and at the same time, with the cooperation of the sealing design, ensure the airtightness of the heat dissipation system, adapt to the vibration and temperature change conditions of the car, and avoid problems such as poor fit and abnormal noise.

[0003] The side panels of a car radiator are usually connected to the radiator with bolts. During car operation, the continuous vibration causes the bolts and threaded holes to rotate relative to each other. If there is no anti-loosening structure, the bolts may come loose and the preload may be lost, resulting in the side panel not fitting tightly to the radiator body, causing abnormal noise or seal failure. Utility Model Content

[0004] To address the aforementioned issues, this application provides a side panel structure for an automotive radiator.

[0005] The technical solution for a car radiator side plate structure provided in this application is as follows:

[0006] A side panel structure for an automotive radiator includes a side panel body and radiator bodies disposed on both sides thereon. Fixing plates are respectively disposed on both sides of the side panel body, and the fixing plates are connected to the corresponding radiator bodies through connecting components.

[0007] The connecting assembly includes a threaded rod passing between the fixed plate and the side plate body, with two nuts threaded onto the threaded rod, the two nuts respectively abutting against the opposite sides of the fixed plate and the side plate body;

[0008] Limiting components are provided on opposite sides of the two nuts to restrict the relative rotation between the nuts and the screw.

[0009] Through the above technical solution, the connecting assembly uses the reverse preload of double nuts to tightly clamp the side plate body, the fixing plate and the radiator body, making the disassembly of the side plate and the radiator more convenient and easy.

[0010] Furthermore, the limiting components are provided in multiple sets, and each set of limiting components includes two fixing rods, with a plate body fixedly connected to the top of the two fixing rods.

[0011] Through the above technical solution, the limiting component uses the rigid engagement of the plug and the nut slot to restrict the rotation of the nut, solving the problem of preload loss caused by vibration or thermal expansion and contraction, and avoiding poor fit, abnormal noise and sealing failure.

[0012] Furthermore, each set of limiting components also includes a sliding plate, with multiple insert rods fixedly connected to the bottom of the sliding plate.

[0013] Furthermore, multiple inserts are inserted into slots inside corresponding nuts.

[0014] Furthermore, each skateboard is slidably connected to a corresponding fixed rod, and each skateboard has a rotating sleeve at its top.

[0015] Furthermore, each plate has an internal threaded connection to a rotating rod, the bottom end of which is rotatably connected to a rotating sleeve.

[0016] Furthermore, a round handle is fixedly connected to the top of each rotating rod.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] (1) By setting the limiting component, this utility model uses the rigid engagement of the plug rod and the nut slot to restrict the rotation of the nut, thereby solving the problem of preload loss caused by vibration or thermal expansion and contraction, and avoiding poor fit, abnormal noise and sealing failure.

[0019] (2) By setting up the connecting components, the present invention uses the reverse pre-tightening force of double nuts to tightly clamp the side plate body, the fixing plate and the radiator body, making the disassembly of the side plate and the radiator more convenient and easy.

[0026] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0027] Reference Figures 1-5 A side panel structure for an automotive radiator includes a side panel body 2 and radiator bodies 1 disposed on both sides thereon. Fixing plates 3 are respectively disposed on both sides of the side panel body 2, and the fixing plates 3 are connected to the corresponding radiator bodies 1 through connecting components.

[0028] The connecting assembly includes a screw 4 that passes between the fixed plate 3 and the side plate body 2, and two nuts 6 are threaded onto the screw 4. The two nuts 6 abut against the opposite sides of the fixed plate 3 and the side plate body 2, respectively.

[0029] Limiting components are provided on opposite sides of the two nuts 6 to limit the relative rotation between the nuts 6 and the screw 4.

[0030] The operator holds the screw 4 and inserts it through the mounting hole of the radiator body 1 on one side, then through the mounting holes of the corresponding side fixing plate 3 and the side plate body 2, and finally out through the mounting hole of the other side fixing plate 3, extending a sufficient length. Then, the first nut 6 near the inner side of the side plate body 2 is screwed in and rotated clockwise until the end face of the nut 6 is tightly fitted with the outer side of the side plate body 2. At this time, a torque wrench is used to apply a preset pre-tightening torque to ensure that the side plate body 2 and the fixing plate 3 are initially fitted. Then, the second nut 6 on the outer side is screwed in, and the same clockwise rotation and pre-tightening torque are applied to make the end face of the second nut 6 tightly abut against the outer side of the fixing plate 3. At this time, the screw 4 is in an axial tension state. The reverse pre-tightening force of the two nuts 6 clamps the side plate body 2, the fixing plate 3 and the radiator body 1 to form a basic fixing structure.

[0031] After the foundation is fixed, the bottom ends of the two fixing rods 5 of the limiting component are welded to the fixing plate 3, and the top ends are firmly connected to the plate body 11 by bolts, so that the plate body 11 is kept horizontal and perpendicular to the axis of the nut 6. The operator holds the round handle 12 above the plate body 11 and rotates the round handle 12 clockwise to drive the rotating rod 10 integrally formed with it to rotate synchronously (the external thread of the rotating rod 10 and the internal thread of the plate body 11 are precisely matched, the thread helix angle is 3°, and it has a certain self-locking property). Since the plate body 11 is relatively fixed to the fixing plate 3 through the fixing rods 5, the rotating rod 10 cannot drive the plate body 11 to move when it rotates, but can only move downward along its own axis. At the same time, the bottom end of the rotating rod 10 is rotatably connected to the rotating sleeve 9 through a deep groove ball bearing. When the rotating rod 10 moves downward, it only transmits axial thrust to the rotating sleeve 9 and will not drive the rotating sleeve 9 to rotate. The rotating sleeve 9 and the slide plate 8 are connected by a key to achieve synchronous movement. Therefore, the rotating sleeve 9 pushes the slide plate 8 to slide smoothly downward along the guide surface of the two fixing rods 5.

[0032] When the slide plate 8 slides down to its limit position, the four evenly distributed rods 7 at its bottom end will be precisely inserted into the four slots opened on the top of the corresponding nut 6. Through the rigid engagement of the rods 7 and the slots, the nut 6 is restricted from rotating around the screw 4.

[0033] At this time, the two nuts 6 are kept in contact by the axial preload of the screw 4 and cannot be loosened by the circumferential limit of the plug 7. Even if the car vibrates continuously during driving or the radiator expands and contracts due to temperature changes during operation, the nuts 6 cannot rotate relative to the screw 4. The preload of the screw 4 remains stable, which ultimately ensures that the side plate body 2 and the two radiator bodies 1 on both sides maintain a tight and stable connection for a long time, avoiding problems such as poor fit, abnormal noise or sealing failure.

[0034] By setting the limiting component, the side plate body 2, the fixing plate 3 and the radiator body 1 are tightly clamped by the reverse pre-tightening force of the double nuts. The rotation of the nut 6 is restricted by the rigid engagement of the plug rod 7 and the nut 6 slot. This solves the problem of pre-tightening force loss caused by vibration or thermal expansion and contraction, and avoids poor fit, abnormal noise and sealing failure.

[0035] Reference Figures 1-4 The limiting components are provided in multiple sets. Each set of limiting components includes two fixing rods 5. The top ends of the two fixing rods 5 are fixedly connected to a plate 11.

[0036] Reference Figures 4-5Each set of limiting components also includes a slide plate 8. The bottom end of the slide plate 8 is fixedly connected to multiple insert rods 7. The multiple insert rods 7 are inserted into the slots inside the corresponding nuts 6. Each slide plate 8 is slidably connected to the corresponding fixed rod 5. Each slide plate 8 is provided with a rotating sleeve 9 at its top. Each plate body 11 is internally threaded with a rotating rod 10. The bottom end of the rotating rod 10 is rotatably connected to the rotating sleeve 9. Each rotating rod 10 is fixedly connected with a round handle 12 at its top.

[0037] Working principle: First, align the fixing plates 3 on both sides of the side plate body 2 with the connecting end faces of the corresponding radiator body 1, ensuring that the screw mounting holes of the fixing plates 3, side plate body 2, and radiator body 1 are coaxial. Then, perform basic fixing. The operator inserts the screw 4 through the mounting hole of one side of the radiator body 1, and sequentially through the mounting holes of the corresponding fixing plate 3, side plate body 2, and the other fixing plate 3, ensuring that the extension length of the screw 4 meets the requirements for the engagement of the double nuts 6. Next, screw in the nut 6 closest to the inner side of the side plate body 2 until its end face is flush with the outer side of the side plate body 2, and apply a preset pre-tightening torque using a torque wrench; then screw in the outer nut 6 and apply the same torque, making it abut against the outer side of the fixing plate 3. At this time, the screw 4 is under axial tension, and the reverse pre-tightening force of the double nuts 6 clamps the side plate body 2, fixing plates 3, and radiator body 1, forming the basic fixing structure.

[0038] After the foundation is fixed, the limiting components are installed. The bottom ends of the fixing rods 5 of multiple limiting components are welded and fixed to the fixing plate 3, and the top ends are connected to the plate body 11 by bolts to ensure that the plate body 11 is horizontal and perpendicular to the axis of the nut 6. The operator rotates the round handle 12 to drive the rotating rod 10 to rotate. Because the rotating rod 10 is threadedly engaged with the plate body 11 and the plate body 11 is fixed, the rotating rod 10 moves downward along the axis. The rotating rod 10 is connected to the rotating sleeve 9, which only transmits axial thrust to the rotating sleeve 9. The rotating sleeve 9 drives the slide plate 8 to slide downward along the fixing rod 5 through a key connection. When the slide plate 8 slides to the limit position, its bottom insert rod 7 is inserted into the slot of the nut 6, which restricts the circumferential rotation of the nut 6 through rigid engagement.

[0039] Ultimately, the axial preload of the double nuts 6 and the circumferential limit of the plug rod 7 form a double guarantee. Even when faced with vehicle vibration or temperature changes, the nuts 6 cannot rotate relative to the screw rod 4, and the preload remains stable, ensuring that the side plate body 2 and the radiator body 1 are tightly connected for a long time, avoiding problems such as poor fit, abnormal noise and sealing failure.

[0040] During disassembly, the operator holds the round handle 12 above the plate 11 and rotates the round handle 12 counterclockwise to drive the rotating rod 10 to rotate synchronously. Because the rotating rod 10 and the plate 11 are threaded together and the plate 11 is fixed, the rotating rod 10 moves upward along its own axis. The rotating rod 10 drives the rotating sleeve 9 to move upward synchronously. The rotating sleeve 9 drives the slide plate 8 to slide upward along the guide surface of the fixed rod 5 through a key connection until the insertion rod 7 at the bottom of the slide plate 8 is completely disengaged from the slot at the top of the nut 6, releasing the circumferential limit on the nut 6. Next, remove the double nuts 6. Use a torque wrench to first unscrew the second nut 6 on the outside, and then unscrew the first nut 6 near the inside of the side plate body 2. Then, pass the screw 4 out through the mounting hole of one side fixing plate 3, and then out of the mounting holes of the side plate body 2, the other side fixing plate 3, and the radiator body 1 in sequence to complete the removal of the screw 4.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
