Description

Technical Field

[0001] The utility model relates to the technical field of automotive parts; more specifically, it relates to an automotive radiator front grille. Background Art

[0002] The automotive radiator front grille, also known as the front grille or intake grille, is an important component at the front of the vehicle. Its main function is to allow air to flow into the engine compartment to help dissipate heat and cool the engine. The automotive radiator front grille is not only an important part of air intake, but also helps to protect internal components, beautify the vehicle body appearance, and improve the performance and efficiency of the vehicle.

[0003] Currently, in the prior art, during the use of the front grille, since the existing front grille usually includes a frame body and several partitions provided on the frame body, a hollow area for air intake and heat dissipation will be formed. During the driving of the vehicle, dust and sundries may enter the vehicle through the hollow area, which may affect the vehicle operation and reduce the practicality of the device to a certain extent. And the existing front grille generally allows gas to flow into the engine compartment through the hollow area during vehicle driving to help the engine and other components dissipate heat. However, the air intake volume of the existing front grille is relatively fixed, and it may not be convenient to quickly dissipate heat when the engine is running at high speed, reducing the heat dissipation effect of the device to a certain extent. Therefore, there is an urgent need for an automotive radiator front grille to solve the above problems. Summary of the Utility Model

[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides an automotive radiator front grille to solve the problems existing in the above background art.

[0005] The utility model provides the following technical solutions: An automotive radiator front grille, comprising:

[0006] A frame, an installation plate is fixedly connected to the outer surface of the frame, and a dust-proof net is snap-fitted inside the front side of the frame. And snap-fit blocks are fixedly connected to the outer surfaces of the four corners of the dust-proof net. A positioning structure is provided on the outer surfaces of the four corners of the front side of the frame. Partition plates are fixedly connected to the inner wall surfaces at both ends of the frame, and there are multiple groups of partition plates. Airflow grooves are opened inside the partition plates, and there are multiple groups of airflow grooves.

[0007] Preferably, the positioning structure includes a clamping groove. Clamping grooves are provided at the four corners inside the front side of the frame. The length and height dimensions of the clamping block are the same as those of the clamping groove inside. An insertion groove is provided on one side inside the clamping groove, and a moving groove is provided on the other side inside the clamping groove. A fixed rod is fixedly connected inside the moving groove, and a spring and a positioning block are sleeved on the outer surface of the fixed rod. The outer surfaces at the four corners of the front side of the frame are hingedly connected with shielding covers. This design can position the dust-proof net through the positioning structure, facilitating the disassembly, cleaning, replacement, and installation of the dust-proof net.

[0008] Preferably, the inner surface of the positioning block fits the outer surface of the clamping block. The outer surface at one end of the positioning block is adapted to the inside of the insertion groove. The two ends of the spring respectively abut against one side surface inside the moving groove and the outer surface at the other end of the positioning block. This design enables the outer surface at one end of the positioning block to be inserted into the insertion groove, and when the positioning block is pulled, the spring's own elasticity can drive the positioning block to reset itself.

[0009] Preferably, the outer dimensions of the positioning block are adapted to the inner dimensions of the moving groove. There are two groups of fixed rods, and the positioning block is sleeved on the outer surfaces of the two groups of fixed rods. This design makes the positioning block more stable during movement and prevents the positioning block from detaching from the inside of the moving groove.

[0010] Preferably, a torsion spring is provided inside the hinge connection of the shielding cover to the frame. A storage groove is provided inside the shielding cover. A pull plate is provided on the outer surface at the other end of the positioning block, and the storage groove covers the outer surface of the pull plate. The self-elasticity of the torsion spring makes the inner surface of the shielding cover always fit the outer surface of the frame, thereby shielding the positioning block through the shielding cover to prevent the positioning block from being accidentally touched by external force and moving.

[0011] Preferably, the outer surface on one side of the partition plate fits the rear surface of the dust-proof net, and the partition plate is narrower at the front and wider at the rear. The air flow groove is an empty groove that is small at both the front and rear ends and large in the middle part. Through the design of the partition plate and the air flow groove, the air flow rate can be increased, thereby increasing the heat dissipation effect of the device to a certain extent.

[0012] The technical effects and advantages of the present utility model: The present utility model can block dust, sundries, etc. encountered during the driving of the vehicle through the dust-proof net, avoiding the situation where dust, sundries, etc. enter the vehicle and may affect the vehicle operation. And through the positioning structure, it is convenient to disassemble, clean, replace, and install the dust-proof net, thereby improving the practicality of the device to a certain extent;

[0013] By designing the shape of the partition plate, the resistance can be reduced, enabling the gas to flow more smoothly, increasing the air flow rate. At the same time, through the design inside the air flow groove, the air flow rate can be increased when the gas enters and exits the air flow groove, and more gas can be stored in the middle of the air flow groove. Thus, with the increase of the air flow rate, more air will participate in the heat exchange on the contact surface between the air flow and the heat source (such as an engine or a radiator), thereby improving the efficiency of convective heat transfer. When the engine is running at high speed, it is convenient to quickly dissipate heat, which to a certain extent improves the heat dissipation effect of the equipment. Moreover, its overall structure is simply and reasonably designed, with high practicability and is easy to promote and apply. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the present utility model will be clearly and completely described in conjunction with the drawings in the present utility model. In addition, the forms of each structure described in the following embodiments are merely examples, and the automotive accessories related to the present utility model are not limited to the structures described in the following embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

[0020] Embodiment 1

[0021] As Figures 1 - 3 shown, this embodiment provides an automotive radiator grille, including:

[0022] Frame 1, a mounting plate 2 is fixedly connected to the outer surface of the frame 1, and a dust-proof net 3 is snap-fitted inside the front side of the frame 1. Moreover, engaging blocks are fixedly connected to the outer surfaces of the four corners of the dust-proof net 3, and a positioning structure 4 is arranged on the outer surfaces of the four corners of the front side of the frame 1. The positioning structure 4 includes an engaging groove 41. The engaging grooves 41 are formed at the four corners inside the front side of the frame 1. And the length and height dimensions of the engaging block are the same as the length and height dimensions inside the engaging groove 41. An insertion groove 42 is formed on one side inside the engaging groove 41, and a moving groove 43 is formed on the other side inside the engaging groove 41. A fixing rod 44 is fixedly connected inside the moving groove 43, and a spring 45 and a positioning block 46 are sleeved on the outer surface of the fixing rod 44. A shielding cover 47 is hingedly connected to the outer surfaces of the four corners of the front side of the frame 1. This design enables the engaging blocks fixedly connected to the outer surface of the dust-proof net 3 to be inserted into the inside of the engaging groove 41, thus facilitating the installation of the dust-proof net 3;

[0023] The inner surface of the positioning block 46 is in contact with the outer surface of the engaging block, and the outer surface of one end of the positioning block 46 is adapted to the inside of the insertion groove 42. Moreover, the two ends of the spring 45 respectively abut against one side surface inside the moving groove 43 and the outer surface of the other end of the positioning block 46. When the user pulls the positioning block 46, the outer surface of one end of the positioning block 46 can be disengaged from the inside of the insertion groove 42. At this time, the disassembly of the dust-proof net 3 can be completed. And when the user releases the positioning block 46, the spring 45 can drive the positioning block 46 to reset itself through its own elasticity, and the outer surface of one end of the positioning block 46 is inserted into the inside of the insertion groove 42;

[0024] The external dimensions of the positioning block 46 are adapted to the internal dimensions of the moving groove 43. There are two groups of fixing rods 44, and the positioning block 46 is sleeved on the outer surfaces of the two groups of fixing rods 44. This design enables the positioning block 46 to move on the outer surface of the fixing rod 44 inside the moving groove 43 when the user pulls the positioning block 46, so that the positioning block 46 can move more stably when moving, and the situation that the positioning block 46 is disengaged from the outer surface of the fixing rod 44 inside the moving groove 43 is avoided;

[0025] A torsion spring is arranged inside the hinge connection of the shielding cover 47 to the frame 1, and a storage groove is formed inside the shielding cover 47. A pulling plate is arranged on the outer surface of the other end of the positioning block 46, and the storage groove covers the outer surface of the pulling plate. This design can hinge and rotate to unfold the shielding cover 47, and the shielding cover 47 can reset itself through the elasticity of the torsion spring after being released, and the storage groove covers the outer surface of the positioning block 46, thus avoiding the situation that the positioning block 46 is accidentally touched and causes its movement. At the same time, the pulling plate facilitates the user to pull the positioning block 46 to move.

[0026] Embodiment 2

[0027] Such as Figure 2 AndFigure 4 As shown, based on the same concept as the above embodiments, this embodiment also proposes:

[0028] Partition plates 5 are fixedly connected to the inner wall surfaces at both ends of the frame 1, and multiple groups of partition plates 5 are provided. Airflow grooves 6 are formed inside the partition plates 5, and multiple groups of airflow grooves 6 are provided. The outer surface of one side of the partition plate 5 is in contact with the rear surface of the dust-proof net 3, and the partition plate 5 is shaped like a narrow front and wide rear. The airflow groove 6 is an empty groove with small front and rear ends and a large middle part.

[0029] In this embodiment, when the vehicle is running, air flows through the outer surfaces of multiple groups of partition plates 5. At this time, the design of the shape of the partition plates 5 can reduce air resistance and increase air velocity. When the air passes through the inside of multiple groups of airflow grooves 6, the air entering and blowing out of the airflow grooves 6 can increase the air velocity, and more gas can be stored in the middle part of the airflow grooves 6. Thus, the heat dissipation effect of the device can be improved by increasing the air velocity.

[0030] Working principle: When the device is in use, the device is installed at the front of the vehicle through the mounting plate 2. Then, the shielding cover 47 is hinged and rotated to unfold, and the positioning block 46 is pulled on the outer surface of the fixed rod 44 inside the moving groove 43, so that the outer surface of one end of the positioning block 46 is disengaged from the inside of the insertion groove 42. At this time, the engaging block on the outer surface of the dust-proof net 3 is engaged with the inside of the engaging groove 41. The self-elasticity of the spring 45 can drive the positioning block 46 to reset itself, so that one end of the positioning block 46 is inserted into the inside of the insertion groove 42 again, and the inner surface of the positioning block 46 is in contact with the outer surface of the engaging block. Thus, the position of the dust-proof net 3 is positioned through the positioning structure 4. At the same time, the self-elasticity of the torsion spring makes the shielding cover 47 reset itself, avoiding the situation that the positioning block 46 is accidentally touched and moves, so as to complete the installation of the dust-proof net 3;

[0031] When the vehicle is running, the dust-proof net 3 can block dust, sundries, etc. encountered during the driving of the vehicle, avoiding the situation that dust, sundries, etc. entering the vehicle may affect the operation of the vehicle. And through the positioning structure 4, it is convenient to disassemble, clean, replace and install the dust-proof net 3. At the same time, the design of the shape of the partition plate 5 can reduce resistance, making the gas flow more smoothly and increasing the air velocity. At the same time, through the design inside the airflow groove 6, the air entering and blowing out of the airflow groove 6 can increase the air velocity, and more gas can be stored in the middle part of the airflow groove 6. Thus, with the increase of the air velocity, more air will participate in the heat exchange on the contact surface between the airflow and the heat source (such as the engine or radiator), thereby improving the efficiency of convective heat transfer. The above is all the working principles of this utility model.
