[0026] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0027] Combine Figures 1 to 5 According to an embodiment of the present invention, a protective device 100 for a vehicle front grille includes: a main body 10, a protective net 20, and a control module 30. The main body 10 is intended to be installed on a vehicle; the protective net 20 is connected to the main body 10, and at least a portion of the protective net 20 is a conductive net; the control module 30 is disposed on the main body 10 and includes a first power supply module 31 electrically connected to the conductive net. When the first power supply module 31 is turned on, it energizes the conductive net to heat the conductive net. Specifically, the main body 10 can be used to connect the protective net 20 and the control module 30, and is suitable for connecting the protective device 100 to the vehicle to enable installation of the protective device 100. The protective net 20 can be placed over the vehicle front grille. The mesh structure of the protective net 20 can prevent tree lint, mosquitoes, and the like from entering the vehicle front grille, thereby reducing damage to the vehicle's exterior and components. More specifically, the protective net 20 is at least partially a conductive net, and the control module 30 has a power supply module for providing electrical energy. After the protective net 20 has been used for a period of time, wood fluff, mosquitoes and other dirt will remain on the net surface. The first power supply module 31 can supply power to the conductive grid to heat the conductive net. The wood fluff and mosquito remains on the net surface will become dry due to heat, and the insect body will usually become more fragile after heating treatment. The user can shake off the residue by patting to clean the net surface, which can facilitate cleaning.

[0028] It should be noted that at least a portion of the protective net 20 is conductive, and the entire protective net 20 may be conductive. This increases the heated area and facilitates cleaning. Alternatively, the conductive net may be located only in the middle region of the protective net 20 or in the region opposite the front safety grille opening. Because the region opposite the front safety grille opening or the middle region of the protective net 20 is likely to be infested with flying insects, electrical heating is required.

[0029] According to an embodiment of the present invention, the protective device 100 for the front grille of a vehicle is provided with a control module 30 and a conductive mesh. The control module 30 can energize the conductive mesh to generate heat, and dirt on the mesh surface can be decomposed by heat to become dry and easy to clean, thereby facilitating the reuse of the protective device 100.

[0030] Specifically, when a vehicle is driving, especially at high speeds, the front grille directs air flow through the air duct, creating a certain attraction. Some insects are attracted to the front of the vehicle by this airflow, and flying insects may collide with the front of the vehicle at high speeds. For these reasons, the user can install a protective net 20 on the front grille to prevent flying insects from entering the vehicle, thereby protecting the vehicle. In the related art, users typically cover the front grille with a mesh cloth. After the mesh cloth becomes adhered to tree lint or flying insect debris, it needs to be cleaned with water. This cleaning method may result in residual flying insect debris, and the mesh cloth needs to be dried before it can be reused, which is inconvenient for the user and reduces the reuse rate. The protective device 100 proposed in the present invention can heat the mesh surface, causing the insect bodies and tree lint of the flying insect debris to become dry and partially charred. The insect bodies are fragile, and the user only needs to shake or pat the mesh surface to make the insect body debris fall off the mesh surface, making the cleaning of the protective net 20 faster and more effective. Optionally, in actual use, the user can adjust the cleaning mode based on the condition of the net surface, for example, adjusting the heating time or temperature, which can be determined based on the amount of tree litter or flying insects on the net surface. Alternatively, the user can shorten the heating time and then swat the insects once they are dry. Alternatively, the user can heat the tree litter or flying insects until they are reduced to ash, so that the user only needs to gently shake to clean the ash.

[0031] Combine Figure 1 and Figure 2 In some embodiments of the present invention, the control module 30 is detachably mounted on the main body 10. That is, the control module 30 can be mounted on the main body 10 when the mesh needs to be cleaned, and removed when the protective device 100 is in use, thereby simplifying the structure of the protective device 100 and improving its convenience during use. Since the mesh of the protective device 100 only needs to be cleaned regularly, the protective device 100 is installed on the vehicle body for a long time during use, and the external environment is relatively complex. Configuring the control module 30 in a detachable form can simplify the structure of the protective device 100, effectively reduce the vehicle counterweight, and protect the control module 30. The control module 30 can be installed when needed, thereby improving the application flexibility of the protective device 100.

[0032] Further, combined with Figure 1 and Figure 4In some embodiments of the present invention, the main body 10 includes a housing 11 and a connecting rod 12. The connecting rod 12 is rotatably disposed within the housing 11. One side of the protective net 20 is connected to the connecting rod 12. Rotation of the connecting rod 12 allows the protective net 20 to be retracted and extended, facilitating storage of the protective device 100 and enhancing its usability. The housing 11 has an opening, through which the other side of the protective net 20 extends or retracts. A cavity can be constructed within the housing 11 to accommodate the connecting rod 12 and the retracted protective net 20, facilitating storage of the protective net 20 and improving the integrity of the protective device 100. The cavity can be approximately cylindrical, minimizing its size and accommodating the rotating connecting rod. The housing 11 can be configured with a cross-section approximately D-shaped, meaning that the housing 11 has a flat mounting surface for easy installation, facilitating interfacing with the vehicle body. The housing 11 is constructed from a combination of flat and curved surfaces. Furthermore, the mounting surface of the housing 11 facilitates the placement of the protective device 100 when it is stored, preventing it from rolling.

[0033] The connecting rod 12 can be used to retract the protective net 20. For example, when the protective device 100 is not needed, the connecting rod 12 can be rotated to wrap the protective net 20 around the connecting rod 12. For example, when a user is driving a vehicle at a slower speed in an urban area and does not need to protect the front bumper, the protective net 20 can be rolled up. In this way, only the shell 11 is installed on the vehicle body, or after the user removes the protective device 100, the structure of the rolled-up protective device 100 is relatively regular, making it convenient for the user to take, place, and store it. In actual application, the connecting rod 12 can be manually driven to rotate, for example, by providing components such as a rocker to facilitate user operation. The free end or movable end of the protective net 20 can be provided with a handle, which can facilitate the user to manually pull out the protective net 20 and unfold the protective net 20.

[0034] In addition, the protective net 20 of the protective device 100 can be rolled up. When in use, the user can adjust the degree of extension and retraction of the connecting rod 12 and the protective net 20 according to needs, and adjust the extended length of the protective net 20 to be suitable for various types of vehicles, which is conducive to improving the versatility of the protective device 100.

[0035] Optionally, the protective net 20 can be a stainless steel soft wire mesh, which has the advantages of good flexibility, retractability, electrical conductivity, high temperature resistance, good corrosion resistance and long service life.

[0036] Furthermore, the connecting rod 12 can also be driven electrically to realize the retraction and extension of the protective net 20. Figure 1 and Figure 5In some embodiments of the present invention, a control module 30 is connected to the housing 11 and located at one end of the connecting rod 12. The control module 30 includes a drive motor 32 connected to the connecting rod 12. The drive motor 32 is used to drive the connecting rod 12 to rotate, thereby enabling automatic retraction and extension of the protective net 20. For example, when the drive motor 32 drives the connecting rod 12 to rotate clockwise, the protective net 20 is retracted, and when it rotates counterclockwise, the protective net 20 is extended. In other words, the control module 30 can be used to energize the conductive grid to generate heat and also drive the connecting rod 12 to rotate to automatically retract the protective net 20, thereby improving the functionality of the protective device 100. Furthermore, in conjunction with the foregoing, the control module 30 can be detachably connected to the main body 10 and can be connected when the protective net 20 is needed. Specifically, in actual use, the protective device 100 can be initially retracted. The user can then install the control module 30 on the main body 10, and the drive motor 32 drives the protective net 20 to unfold. After unfolding, the user can remove the control module 30 and store it inside the vehicle. When the protective net 20 needs to be cleaned after being used for a period of time, the user can install the control module 30 on the main body 10 again, and the first power supply module 31 energizes the guide grid to clean the net surface by heating. After cleaning, the driving motor 32 can be directly used to roll up the protective net 20 to facilitate the storage of the protective device 100.

[0037] More specifically, in some embodiments of the present invention, the connecting rod 12 is provided with a first and a second spaced-apart connecting wire, one end of each of the first and second connecting wires extending to the control module 30; the other ends of the first and second connecting wires are respectively connected to the conductive grid, so that the first power supply module 31 can supply power to the conductive grid through the connecting rod 12. For example, the first connecting wire can be between the conductive grid and the positive pole of the power supply module, and the second connecting wire can be between the conductive grid and the negative pole. The connecting rod 12 has a cleaning position. When the connecting rod 12 is rotated to the cleaning position, the first connecting wire is connected to the positive pole of the first power supply module 31, and the second connecting wire is connected to the negative pole of the first power supply module 31. Thus, the use state and the cleaning state are separated, which can avoid accidentally turning on the cleaning function while driving, prevent the risk of fire, and improve safety during use.

[0038] Combine Figure 3The housing 11 has a first port at one end where the control module 30 is mounted. The main body 10 also includes a first cover 41. The first cover 41 is a sealing cap, and either the first cover 41 or the control module 30 can be installed on the first port to seal it. That is, when the control module 30 is removed from the housing 11, the first cover 41 can be installed on the housing 11 to seal the first port, improving the integrity of the protective device 100. Furthermore, when cleaning the protective net 20, the first cover 41 is removed to open the first port, and the control module 30 is installed on the first port to heat the conductive net. After heating, the burnt insect debris on the net can be patted with the first cover 41 to separate the debris, dust, and ash from the net, making it easier for the user to clean. In other words, when the control module 30 is not required, the first cover 41 can be used to seal the first port, maintaining the appearance of the housing 11 and isolating the interior of the housing 11 from the external environment.

[0039] Combine Figure 2 In some embodiments of the present invention, the housing 11 has a first port and a second port formed at its two ends, respectively. The protective device 100 further includes a first bearing 51 and a second bearing 52 disposed within the housing 11 and adjacent to the first port and the second port. The two ends of the connecting rod 12 engage with the first bearing 51 and the second bearing 52, respectively, to facilitate rotation of the connecting rod 12. The protective device 100 further includes a first cover 41 and a second cover 42. The first cover 41 is connected to the first port, and the second cover 42 is connected to the second port. The first cover 41 and the second cover 42 can seal the two ends of the housing 11, namely the first port and the second port, thereby improving the integrity of the protective device 100 and facilitating separation of the inside and outside of the housing 11. The inner wall of the housing 11 is provided with a first positioning protrusion 111 and a second positioning protrusion 112 for respectively positioning the first bearing 51 and the second bearing 52. The first bearing 51 is located between the first positioning protrusion 111 and the first cover 41, and the second bearing 52 is located between the second positioning protrusion 112 and the second cover 42. Thus, the first positioning protrusion 111 and the first cover 41 can axially position the first bearing 51; the second positioning protrusion 112 and the second cover 42 can axially position the second bearing 52. Specifically, the positioning protrusion can be a single protrusion, or a plurality of protrusions spaced apart circumferentially along the inner wall of the housing, or a protruding ring extending circumferentially along the inner wall of the housing.

[0040] Specifically, combined Figure 2 and Figure 3 The first cover 41 can be snap-fitted to the housing 11, and the control module 30 can also be snap-fitted to the housing 11. Figure 2 and Figure 5The control module 30 may include a main body portion 30a and a limiting portion 30b. The limiting portion 30b is connected to one side of the main body portion 30a. During assembly, the limiting portion 30b is snap-connected to the housing 11. After the control module 30 is assembled, the limiting portion 30b of the control module 30 may cooperate with the first positioning protrusion 111 to position the first bearing 51. One axial end of the first bearing 51 abuts against the first positioning protrusion 111, and the limiting portion 30b abuts against the other axial end of the first bearing 51, thereby achieving axial limitation of the first bearing 51. The connection structure of the first cover 41 may be the same as that of the control module 30, so that both can be connected to the housing 11.

[0041] The second cover 42 and the housing 11 can also be snap-fitted for easy repair and maintenance. During assembly, the second bearing 52 can be mounted on the connecting rod 12. After the second cover 42 is mounted, it can cooperate with the second positioning protrusion 112 to position and limit the second bearing 52.

[0042] More specifically, combined with Figure 2 The connecting rod 12 has a rod portion 122, a first end portion 123, and a second end portion 124 at each end. The first end portion 123 is connected to the rod portion 122, with a first stop member 125 disposed therebetween. The second end portion 124 is connected to the rod portion 122, with a second stop member 126 disposed therebetween. The first bearing 51 is sleeved on the first end portion 123 and abuts against the first stop member 125. The second bearing 52 is sleeved on the second end portion 124 and abuts against the second stop member 126. Both the first bearing 51 and the second bearing 52 have an inner ring and an outer ring. The inner ring is fixedly connected to the first end portion 123 and the second end portion 124, and rotates relative to the outer ring.

[0043] Combine Figure 2In other embodiments of the present invention, a first cover 41 is mounted on the first port and has a through-hole through which a portion of the connecting rod 12 extends. The control module 30 is mounted on the first cover 41 to connect to the connecting rod 12. Specifically, in conjunction with the foregoing, the connecting rod 12 is provided with a shaft portion 121 adapted to connect to the control module 30. The shaft portion 121 is connected to the end of the first end portion 123 facing away from the rod portion 122. After the first cover 41 is mounted on the first port, the shaft portion 121 can extend out of the housing 11 through the through-hole. Because the first end portion 123 is also connected to the shaft portion 121, the length of the connecting rod 12 on the first end portion 123 side is different from the length of the second end portion 124. During production and manufacturing, if the first and second end caps have the same thickness, this facilitates manufacturing. In this way, the second end cap can enclose the second end portion 124 within the housing 11, while the first end cap can enclose the first end portion 123 within the housing 11, while the shaft portion 121 extends out of the through-hole. This design facilitates simultaneous manufacturing of the first cover 41 and the second cover 42, requiring only the perforation to be provided on the first cover 41, thereby reducing manufacturing costs. Of course, the first cover 41 and the second cover 42 may also be constructed separately, with the first cover 41 being configured to also enclose the shaft portion 121 within the housing 11.

[0044] Alternatively, the first cover 41 may be mounted on the first port and have a perforation, and the control module 30 may be detachably mounted on the first cover 41 and connected to the connecting rod 12 via the perforation. In this way, the control module 30 may be directly disassembled as needed without disassembling the first cover 41.

[0045] Combine Figure 1 and Figure 2In some embodiments of the present invention, one side of the protective net 20 is connected to the main body 10, and the protective device 100 also includes a fixed net portion 60 connected to the other side of the protective net 20, which can fix the other side of the protective net 20 to the vehicle, wherein at least one of the main body 10 and the fixed net portion 60 is provided with a magnetic element, thereby allowing the protective net 20 to be fixed by magnetic attraction, or the main body 10 to be installed on the vehicle by magnetic attraction for easy connection. For example, both the main body 10 and the fixed net portion 60 are provided with magnetic elements. During assembly, the main body 10 is magnetically attracted to the vehicle body, and the unfolded protective net 20 is magnetically attracted to the vehicle body and fixed by magnetic attraction. The fixing effect is good, the versatility is high, and the assembly and disassembly are simple. In the related art, when installing the mesh, the mesh is usually covered on the front of the vehicle, and binding points are found in the four corners of the front of the vehicle to fix the four corners of the fine mesh, which is relatively complicated to install. In the present application, the protective device 100 can be installed on the vehicle body by magnetic attraction, which allows for quick installation and removal, and there are no restrictions on the assembly position, providing a good assembly experience. In addition, in conjunction with the above, the protective net 20 is in a retractable form, that is, the user can adjust the unfolded size of the protective net 20 according to usage requirements, such as the size of the vehicle body, thereby improving practicality. Since the protective net 20 is assembled by magnetic attraction, there are no requirements or restrictions on the installation position, which can improve the flexibility of assembly to better meet user needs.

[0046] Combine Figure 1 and Figure 2 In some embodiments of the present invention, a magnetic attraction component is provided on the fixed net portion 60 and is an electromagnetic magnetic attraction component, which can use the electromagnetic principle to generate attraction.

[0047] Optionally, the protective device 100 may further include a second power supply module (not shown), which is connected to the electromagnetic magnetic element to supply power. The second power supply module supplies power to the electromagnetic magnetic element, which enables the electromagnetic magnetic element to generate magnetic attraction.

[0048] Here, the second power supply module can be provided in the control module 30. In this case, the second power supply module can be connected to the electromagnetic magnetic component in the fixed net part 60 through the connecting rod 12 and the wires on the protective net 20. The second power supply module can also be provided in the fixed net part 60, and the power supply is controlled by manually adjusting the switch of the second power supply module. In this way, the electromagnetic magnetic component can be controlled individually, thereby improving the flexibility during use. For example, when retracting the protective net 20, in order to prevent the fixed net part 60 from being magnetically attracted to the vehicle body, the power supply function of the power supply module can be turned off, and the second power supply module can be turned on when the protective net 20 needs to be magnetically fixed to the vehicle body.

[0049] Combine Figure 1 and Figure 2A connecting wire 70 is provided between the protective net 20 and the fixed net portion 60, so that the fixed net portion 60 can be movably connected to the protective net 20, which is beneficial to improving the flexibility of the fixed net portion 60. Optionally, the connecting wire 70 can be an insulated wire to avoid short circuit and improve safety in use.

[0050] Combine Figure 4 The fixed net part 60 can limit the extreme position of the protective net 20 when it is rolled up, that is, after the protective net 20 is rolled up, the side where the protective net 20 is connected to the fixed net part 60, the opening of the shell 11 where the fixed net part 60 is restricted, that is, after the protective net 20 is rolled up, the protective net 20 is stored in the shell 11, and the fixed net part 60 is located outside the shell 11.

[0051] Combine Figure 5 The control module 30 includes a first power supply module 31, a drive motor 32, and a low-voltage power supply module 33. The first power supply module 31 is used to supply power to the conductive grid. It should be noted that the power supply from the first power supply module 31 to the conductive grid must be within a safe range for humans. For example, the voltage on the conductive grid is high but the current is low, or the voltage on the conductive grid is low but the current is high, to ensure that people will not be in danger if they accidentally touch it.

[0052] Specifically, the driving motor 32 is connected to the low-voltage power supply module 33 , and the low-voltage power supply module 33 is used to supply power to the driving motor 32 .

[0053] Therefore, the control module 30 can have both driving and power-on functions at the same time, and the two functions need to be shielded from each other and not affect each other. The control module 30 has good compatibility and integrates multiple modules, so that the control module 30 has the four functions of "power on", "deployment", "power off (OFF)" and "retraction" at the same time, which is beneficial to improve the functionality of the protective device 100.

[0054] The vehicle according to the embodiment of the present invention comprises: a vehicle body, the aforementioned protective device 100 for the front grille, a front grille being provided on the front side of the vehicle body; and the protective device 100 being covered on the front grille.

[0055] The vehicle according to the embodiment of the present invention can prevent tree lint, mosquitoes, etc. from entering the front grille, thereby reducing damage to the vehicle appearance and components. In addition, the protective device 100 is easy to clean, which provides convenience for users.

[0056] Specifically, the protective device 100 can be installed on the front panel or hood of the vehicle, and the front grille, center grille and radiator of the vehicle can be covered with the protective net 20 to intercept debris such as tree catkins or mosquito debris blown by the wind during the driving of the vehicle. It can effectively prevent all kinds of debris from directly adhering to the front grille, center grille and radiator, etc., reduce the frequency of the driver's cleaning of the front grille, center grille and other front accessories of the vehicle, reduce the impact of debris entering the radiator on the heat dissipation performance and effectively improve the service life of the radiator. Therefore, the protective device 100 proposed in this application is easy to use and arrange, and has a high degree of universality.

[0057] A protective device 100 according to a specific embodiment of the present invention will be described below with reference to the accompanying drawings.

[0058] Combine Figures 1 to 5 The protective device 100 comprises a control module 30, a protective net 20, a main body 10, a bearing, and a cover. The main body 10 includes a housing 11 and a connecting rod 12. The housing 11 is constructed as a cylindrical cavity with a mounting surface for easy installation on the vehicle body. The mounting surface has a controllable strong magnetic property that can attract the magnetic housing 11 assembly to metal parts. The two open ends of the cylindrical cavity are respectively equipped with a first cover body 41 and a second cover body 42, and the cover body height is 10mm. The cover body is fixed to the two ends of the cylindrical cavity by a snap connection to seal and prevent dust, and at the same time limit the bearing. There is a circular hole in the middle of the first cover body 41 to avoid the exposed spline end of the shaft 121 of the connecting rod 12, and the second cover body 42 is a solid cover without a circular hole; a detachable bearing is provided at the left and right ends of the magnetic shell 11 assembly, and the outer end faces of the left and right bearings are 10mm (sunken) away from the left and right end faces of the magnetic shell 11 assembly respectively. This size is ensured by the positioning protrusion limiter inside the shell 11; the connecting rod 12 is fixed in the housing 11 by left and right bearings (interference fit) and can rotate freely but will not move axially. The axial limit here is ensured by the boss on the connecting rod 12 and the inner ring of the bearing; the left end of the connecting rod 12 is exposed 5mm from the outer end face of the bearing, and the right end of the connecting rod 12 is exposed 25mm from the outer end face of the bearing, and the outer 20mm is an external spline structure. The middle area of ​​the connecting rod 12 (i.e., between the left and right bearings) is connected to the upper side of the protective net 20. The protective net 20 can be retracted and unfolded by rotating the connecting rod 12. Three magnetic absorbers (i.e., the fixed net part 60) are evenly arranged under the protective net 20. The magnetic absorbers have controllable strong magnetism.

[0059] Furthermore, the control module 30 is an assembly of devices that integrates a drive motor 32 and a low-voltage power supply module 33, and has two functions of driving and power supply. A combination switch controls "power on", "unfold", "power off (OFF)", and "retract". The output shaft of the drive motor 32 in the control module 30 is an internal spline structure, which matches the external spline of the shaft 121 at the right end of the connecting rod 12. The output end interface structure of the control module 30 is the same as the cover body. The control module 30 can be fixed to the right end of the shell 11 by a snap connection. When the control module 30 is fixed to the right end of the shell 11, the internal spline of the output shaft of the drive motor 32 in the control module 30 matches the external spline at the right end of the connecting rod 12 to form a complete drive chain and conduction chain.

[0060] When the protective device 100 is in a non-working state, the protective net 20 is in a retracted state and is located in the inner cavity of the shell 11. The three magnetic absorbers below the protective net 20 are fixed at the lower opening of the shell 11. Left and right side covers are respectively installed at both ends of the shell 11, and the control module 30 is placed separately.

[0061] When the protective device 100 needs to be used, the protective device 100 needs to be installed on the front of the vehicle, find the large surface of the front of the vehicle or the large surface of the hood, stick the installation surface of the shell 11 on the large surface of the vehicle and turn on the magnetic function after adjusting it to the appropriate position, and securely fix the shell 11 on the front of the vehicle or the hood. Then remove the right side cover of the shell 11, replace it with the control module 30, put the switch in the "deploy" position, and the protective net 20 starts to unfold until the protective net 20 completely covers the front grille, the middle grid and the radiator area of ​​the vehicle. Turn off the switch, and then arrange the three controllable magnetic absorbers under the protective net 20 at the appropriate position on the lower edge of the front wall to ensure that the protective net 20 is flat and unfolded, and then turn on the magnetic function to fix it; finally, remove the control module 30 and replace it with the right side cover of the shell 11.

[0062] After a period of driving, if the protective net 20 of the front grille guard 100 accumulates a lot of tree lint and mosquito debris, and the net 20 needs to be cleaned, the vehicle can be parked in a safe area. The three controllable magnetic attractors below the protective net 20 are turned off but not released. Then, the right cover of the housing 11 is removed, the motor module is installed, and the switch is set to the "power on" position. More specifically, turning off the magnetic attraction prevents the two circuits of the fixed net 60 and the control module 30 from intersecting, thereby preventing a short circuit.

[0063] At this time, the control module 30 shields the drive motor 32 and enters the power-on cleaning mode. The entire stainless steel wire mesh is connected to a 12V or 24V voltage and current. The tree fluff and mosquito debris on the stainless steel wire mesh begin to heat until they turn into ashes. At this point, the control switch can be turned off, and then the right cover can be used to gently tap the stainless steel wire mesh to clean the ashes on the mesh. After cleaning the stainless steel wire mesh, you can choose to continue using the car front grille protection device 100 or put it away.
