Description

Technical Field

[0001] This utility model belongs to the technical field of front cover technology for heavy trucks, and particularly relates to a front cover for heavy trucks. Background Technology

[0002] The front cover of a heavy truck is a plate-shaped exterior decorative piece located at the front of the heavy truck vehicle, below the windshield and above the bumper, serving functions such as shielding and decoration.

[0003] Heavy truck front grilles lack an effective filtration structure that does not affect normal air intake requirements. Traditional air intake grilles can only block larger foreign objects, such as leaves and flying stones, but they are difficult to effectively block smaller flying catkins. Especially in recent years, flying catkins in various places during spring and summer have caused great inconvenience to vehicle owners. Some vehicle owners choose to use external filter screens for protection. External filter screens not only affect the overall aesthetics of the vehicle, but also, after a period of use, their small mesh will greatly reduce the efficiency of the vehicle's air intake.

[0004] Therefore, it is necessary to improve the front cover of heavy trucks in the existing technology. Utility Model Content

[0005] The purpose of this invention is to overcome the defects in the existing technology and provide a front cover for heavy trucks that improves the filtration effect of small foreign objects.

[0006] To achieve the above objectives, the specific technical solution of the heavy-duty truck front cover of this utility model is as follows:

[0007] A front cover for a heavy-duty truck includes a main body with an air inlet, a mesh screen detachably connected to the back of the main body, the mesh screen covering the air inlet, and a vibration mechanism for cleaning the mesh screen; the vibration mechanism includes an elastic rod and a striking block, the striking block being connected to the mesh screen via the elastic rod.

[0008] Preferably, the back of the mask body is integrally formed with a mounting frame, the air inlet is located inside the mounting frame, the isolation net has an outer frame that matches the mounting frame, and the outer frame is sealed to the mounting frame by screws.

[0009] Preferably, the inner side of the mounting frame is provided with a support strip for supporting the isolation net.

[0010] Preferably, the mounting frame is slidably provided with an inertial seat along the extension direction of the support bar, and the two ends of the elastic rod are respectively connected to the inertial seat and the striking block. The striking block is arranged opposite to the support bar, and protrusions are provided on the opposite sides of the striking block and the support bar. The protrusions are arranged at equal intervals along the extension direction of the support bar.

[0011] Preferably, the support bar and the striking block are provided with a lubricating layer on their opposite sides.

[0012] Preferably, a sliding rod is fixedly connected to the mounting frame parallel to the extension direction of the support bar, the inertial seat has a sliding sleeve that slides with the sliding rod, the sliding rod is fitted with a spring, and the two ends of the spring are respectively connected to the sliding sleeve and the end of the sliding rod.

[0013] Preferably, there are multiple sliding rods, and the number of sliding sleeves is the same as the number of sliding rods and corresponds one-to-one.

[0014] Preferably, the inertial seat is provided with a plug-in block, and one end face of the elastic rod is provided with a plug-in interface for plugging into the plug-in block. The elastic rod of the plug-in block is also provided with a bolt that is threaded into the plug-in block.

[0024] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0025] The terms "top surface," "bottom surface," and "follow surface" refer to the normal operating state of the front cover of a heavy truck. They are used only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] like Figure 1 and 2 As shown, a front cover for a heavy truck includes a main body 1 with an air inlet 101. An isolation net 2 is detachably connected to the back of the main body 1. The isolation net 2 covers the air inlet 101, and a vibration mechanism 3 for cleaning the isolation net 2 is provided on the isolation net 2. The vibration mechanism 3 includes an elastic rod 303 and a striking block 304. The striking block 304 is connected to the isolation net 2 through the elastic rod 303.

[0027] The aforementioned front cover is applicable to, but not limited to, heavy-duty trucks. During vehicle operation, external airflow enters the vehicle through the air intake 101 to dissipate heat. Larger debris carried by the airflow is blocked by the cover body 1, and then the airflow passes through the isolation net 2, which filters out fine impurities, reducing the amount of impurities entering the vehicle and maintaining its heat dissipation performance, thus lowering the vehicle's failure rate. During vehicle operation, the vehicle's movement causes the striking block 304 to move. The striking block 304 repeatedly impacts the isolation net 2, loosening and dislodging accumulated impurities, thus cleaning the isolation net 2, improving its filtration and ventilation effects, further reducing the amount of impurities in the airflow entering the vehicle, and lowering the vehicle's failure rate. The striking block 304 is driven by the vehicle's movement or vibration, requiring no additional power, thereby improving the vehicle's energy efficiency.

[0028] Further improvements include, for example Figure 2 and 3As shown, a mounting frame 102 is integrally formed on the back of the mask body 1. The air inlet 101 is located inside the mounting frame 102. The isolation net 2 has an outer frame 201 that matches the mounting frame 102. The outer frame 201 is sealed to the mounting frame 102 by screws. The mounting frame 102 has multiple threaded holes spaced apart along its extension direction, and the outer frame 210 has multiple through holes spaced apart along its extension direction. The number of through holes is the same as the number of threaded holes and they correspond one-to-one. After the screws pass through the through holes, they are threaded to the threaded holes, thereby achieving mutual fixation between the mounting frame 102 and the outer frame 201, improving the ease of installation and removal of the isolation net 2. A sealing ring is provided around the mounting frame 102 to achieve mutual sealing between the mounting frame 102 and the outer frame 201, preventing air leakage and ensuring the filtering effect of the isolation net 2 on the airflow.

[0029] Further improvements include, for example Figure 4 and 5 As shown, a support strip 202 is provided on the inner side of the mounting frame 102 to support the isolation net 2. The support strip 202 is provided to support the isolation net 2, prevent the isolation net 2 from deforming under the action of wind, so as to improve the firmness of the isolation net 2, thereby extending the service life of the isolation net 2 while ensuring its filtration effect.

[0030] Further improvements include, for example Figure 4-6 As shown, an inertia seat 301 is slidably provided on the mounting frame 102 along the extension direction of the support bar 202. The two ends of the elastic rod 303 are connected to the inertia seat 301 and the striking block 304 respectively. The striking block 304 is positioned opposite the support bar 202, and protrusions 204 are provided on the opposite sides of the striking block 304 and the support bar 202. The protrusions 204 are arranged at equal intervals along the extension direction of the support bar 202. Specifically, the inertia seat 301 is slidably connected to the mounting frame 102 vertically. When the vehicle is moving, the inertia seat 301 moves back and forth vertically under the drive of the vehicle's inertial force, thereby driving the striking block 304 to rise and fall. The elastic rod 303 applies a spring force to the striking block 304 in the direction of the support bar 202. During the rising and falling of the striking block 304, the protrusion 204 pushes the striking block 304 away from the support bar 202, and the spring force of the elastic rod 303 pushes the striking block 304 closer to the support bar 202, thereby causing the striking block 304 to repeatedly strike the support bar 202, thereby causing the isolation net 2 to vibrate and causing the impurities accumulated on the isolation net 2 to fall off, thus achieving the cleaning effect of the isolation net 2. The support bar 202 can also withstand the impact force of the striking block 304, preventing the impact force from acting directly on the isolation net 2, thereby reducing the probability of the isolation net 2 being damaged due to excessive force, and extending the service life of the isolation net 2.

[0031] A further improvement is that a lubricating layer is provided on the opposite sides of the support bar 202 and the striking block 304. The lubricating layer is a polytetrafluoroethylene layer. The lubricating layer can reduce the friction between the support bar 202 and the striking block 304, thereby slowing down the wear rate between the two and extending the service life of the equipment. It can also reduce the resistance between the striking block 304 and the support bar 202, making the movement of the striking block 304 more flexible and smooth. The two sides of the protrusion 204 located in the direction of movement of the striking block 304 can also be chamfered to reduce the resistance encountered by the striking block 304 when it rises and falls.

[0032] Further improvements include, for example Figure 5 and 6 As shown, a sliding rod 203 is fixedly connected to the mounting frame 102 parallel to the extension direction of the support bar 202. The inertia seat 301 has a sliding sleeve 302 that slides with the sliding rod 203. A spring 306 is fitted onto the sliding rod 203, and the two ends of the spring 306 are respectively connected to the sliding sleeve 302 and the end of the sliding rod 203. The spring 306 can play a buffering role to prevent the inertia seat 301 from directly impacting the outer frame 201. In addition, the extension and retraction of the spring 306 can also promote the lifting and lowering movement of the inertia seat 301 to improve the cleaning effect of the striking block 304 on the isolation net 2.

[0033] Further improvements include, for example Figure 4 As shown, multiple slide bars 203 are provided, and the number of sliding sleeves 302 is the same as the number of slide bars 203 and corresponds one-to-one. Two slide bars 203 and two sliding sleeves 302 respectively can realize the positioning of the inertia seat 301, improve the stability of the inertia seat 301 installation, and thus improve the stability of the striking block 304 installation.

[0034] Further improvements include, for example Figure 6 As shown, the inertia seat 301 is provided with a plug-in block 305, and one end face of the elastic rod 303 is provided with a plug-in interface for plugging into the plug-in block 305. The plug-in block 305 and the elastic rod 303 are also provided with bolts that are threaded into the plug-in block 305. The elastic rod 303 and the inertia seat 301 are connected and disconnected by bolts, which can improve the convenience of replacing the striking block 304, thereby improving the convenience of vehicle maintenance.

[0035] Further improvements include, for example Figure 6 As shown, the inertia seat 301 has a ventilation slot 307. The ventilation slot 307 reduces the obstruction of airflow by the inertia seat 301, thereby increasing the vehicle's air intake and ensuring stable vehicle operation.
