Description
Technical Field
[0001] This utility model relates to the field of vehicle technology, specifically to a light truck cab air intake and rain shield device. Background Technology
[0002] In the process of realizing this utility model, the inventors discovered that: Currently, about 70% of light truck cabs on the market have a non-removable rain shield for the front air intake (fixed by welding). The air conditioning external circulation intake directly opposite the front air intake has a simple filter. When the vehicle operates the air conditioning external circulation in harsh environments, a large amount of dust is drawn into the air conditioning unit and the cab from the filter below the rain shield. Excessive dust inside the cab severely affects the driving and riding experience and also impacts the air conditioning's cooling efficiency. Given the frequent after-sales service requests and serious complaints from end customers due to this issue, the usual after-sales solution is to remove the dashboard and replace the air conditioning unit. However, this method is costly, inefficient, and time-consuming. Summary of the Invention
[0003] In order to solve the problems existing in the prior art, this utility model proposes a light truck cab air intake rain shield device.
[0004] Inventive Concept: Currently, a rain shield is welded to the surface of the air intake on the front of the light truck cab. A gap exists between the bottom of the rain shield and the air intake, allowing a large amount of dust to enter simultaneously with airflow. The passage between the air intake and the cab is only equipped with a simple filter for the air conditioner's external circulation, resulting in dust being drawn into the air conditioning unit evaporator and into the cab, and making disassembly and maintenance difficult. Furthermore, the existing rain shield has an opening at the bottom, allowing water flowing back from the front panel to be drawn into the air intake through the bottom opening of the rain shield. To address these issues, this invention proposes a solution that addresses the problem by redesigning the air intake location and implementing a removable pre-filter.
[0005] Therefore, the technical solution of this utility model is as follows: a light truck cab air intake and rain protection device, including a cab front cover, a front cover air inlet on one side of the cab front cover, an air conditioner inside the front cover air inlet, and a front panel installed on the outer surface of the cab front cover, characterized in that: A detachable mounting base is provided on the outside of the air inlet of the front bulkhead. The mounting base is hollow inside with openings at both the front and rear ends. A cross-shaped bracket is provided at the end of the mounting base near the front bulkhead of the cab. The mounting base is provided with a first filter layer and a second filter layer from the inside to the outside. An air intake guide plate connected to the mounting base is provided outside the second filter layer. A rain cover is provided on the outside of the air intake guide plate. The rain cover is fastened to the welded bolts of the front bulkhead of the cab by nuts. A sealing gasket is provided between the rain cover and the front bulkhead of the cab. The sealing gasket has bolt through holes. The rain cover has a skirt around its outer perimeter, with corresponding bolt mounting holes on the skirt. One side of the rain cover has a side air inlet, which is connected to the air intake guide plate.
[0006] A further improvement to the above technical solution is that: the mounting base has extensions on both sides near the front of the cab, and the outer periphery of the mounting base near the front of the cab has an outwardly turned flange. The extensions have mounting holes adapted to the front of the cab, and also have bolt posts for fixing the air intake deflector. Reinforcing ribs are provided between the extensions and the side wall of the mounting base. The purpose is to ensure the mounting base's installation on the front of the cab and its supporting strength, while also facilitating the installation of the air intake deflector.
[0007] A further improvement to the above technical solution is that the air intake guide plate includes a rectangular frame, within which inclined downward grilles are spaced from top to bottom. Adjacent grilles are staggered and connected as a whole by vertical reinforcing ribs. On both sides of the rectangular frame are outwardly extending mounting blocks, each with mounting holes corresponding to bolt posts. The air intake guide plate is fixed to the mounting base by screws. The air intake guide plate guides the incoming airflow and simultaneously limits and fixes the first and second filter layers.
[0008] A further improvement to the above technical solution is that the upper and lower borders of the rectangular frame are provided with inward protrusions at intervals. The purpose is to increase the strength of the rectangular frame and prevent it from warping.
[0009] A further improvement to the above technical solution is as follows: the outer surface of the rain cover is provided with crisscrossing reinforcing ribs, and the outer contour of the rain cover is also provided with grooves where no interference is formed, and the corners are rounded; the side air inlet of the rain cover extends downward and connects with the water outlet located at the bottom of the side of the rain cover, and both the side air inlet and the water outlet are provided with water-resistant skirts. The reinforcing ribs can prevent the rain cover from deforming, and the purpose of providing grooves on the outer contour is to minimize the outer contour size of the rain cover as much as possible. By transforming sharp turns or connections into smooth curves, the performance, safety, aesthetics, and user experience of the product are optimized; the side air inlet, water outlet, and water-resistant skirts prevent water from entering from the front air inlet.
[0010] A further improvement to the above technical solution is as follows: the first filter layer uses corrugated non-woven fabric and is fixed by a frame; the second filter layer uses sponge with a density of 20-40 kg / m³. The high-density sponge filters the air while regulating airflow and providing support and protection; the corrugated non-woven fabric creates a three-dimensional structure from the flat fabric, increasing the effective filtration area within a limited space. A larger area means less air resistance (wind resistance) and improved air intake efficiency.
[0011] Beneficial effects: Compared with existing technologies, the advantages of this patent are as follows: First, the addition of two filter layers, a double-layer filter of sponge and non-woven fabric, can effectively filter dust and dirt, purify the air conditioner body, block dust pollution inside the driver's cab, significantly extend the service life of the air conditioner, significantly improve the driving experience, effectively reduce after-sales claims, and allow for quick removal and replacement during maintenance; Second, the adoption of a detachable side-suction water deflector simplifies the rain cover structure, reduces costs without affecting rain protection, and allows for quick removal and replacement of the rain cover during vehicle maintenance, effectively improving after-sales service efficiency and greatly reducing service and claim costs.
