Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to a combined wind shield for a top-mounted expansion water tank of a light truck. Background Art

[0002] The windshield is a crucial component in the vehicle chassis, typically mounted behind the radiator. Its primary function is to direct and concentrate airflow, allowing it to flow evenly through the radiator. This enhances the radiator's cooling efficiency and ensures that components, including the vehicle's engine, operate at optimal temperatures.

[0003] In the prior art, the wind shield and expansion tank systems operate independently and do not interfere with each other. The wind shield is responsible for directing outside air to the radiator, promoting heat exchange and ensuring normal engine heat dissipation. The expansion tank replenishes coolant, provides the necessary space for the coolant's thermal expansion and contraction, and facilitates the observation of the coolant capacity in the cooling system. For example, there is a certain amount of space inside the expansion tank. When the coolant temperature rises and its volume expands, excess coolant flows into the expansion tank. When the coolant temperature drops and its volume contracts, the coolant in the expansion tank flows back into the cooling system, thereby maintaining stable pressure and coolant capacity in the cooling system. At the same time, its liquid level indicator allows operators to easily check the remaining coolant amount at any time.

[0004] Existing windshield structures have at least the following drawbacks: They merely serve the basic function of guiding airflow, and are independently designed from components such as the expansion tank bracket, rather than forming an integrated whole. This results in a large number of parts, increasing production costs and the complexity of the vehicle layout. Utility Model Content

[0005] The embodiment of the present application solves the technical problem of the large number of parts caused by the independent arrangement of the wind shield and the expansion tank bracket in the prior art by providing a combined wind shield for a top-mounted expansion tank of a light truck, thereby reducing production costs.

[0006] In order to solve the above technical problems, the present utility model adopts the following technical solution: a combined wind shield for a top-mounted expansion water tank of a light truck, comprising a base plate, a transition ring, and a wind shield. The base plate and the wind shield are connected by a transition ring, and a limit column and a fixed bracket are provided on the transition ring. The limit column can be embedded in the water tank mounting hole of the expansion water tank, and the fixed bracket is pre-embedded with an expansion water tank mounting nut, which can be connected to the expansion water tank by bolts.

[0007] Since the transition ring is provided with a limit column and a fixed bracket, the limit column can be placed in the water tank mounting hole of the expansion tank, and the fixed bracket can be connected to the expansion tank, so the wind shield and the expansion tank bracket can be integrated, thereby shortening the cooling pipe length and reducing the coolant filling amount. At the same time, the number of parts is reduced, the production efficiency is improved, and the cost and weight are greatly reduced.

[0008] Furthermore, the bottom plate is provided with a radiator mounting hole and a notch for the radiator water inlet pipe to pass through; the notch can ensure the installation space of the radiator water inlet pipe.

[0009] Furthermore, the radiator mounting hole is an oblong hole; the oblong hole can adjust the position of the wind shield relative to the fan in the vertical direction to ensure that the gap between the fan and the wind shield is uniform.

[0010] Furthermore, a boss is provided on the periphery of the radiator mounting hole; stress concentration can be effectively avoided by the boss.

[0011] Furthermore, the wind shield is in the form of a ring; thereby the center of the wind shield is made concentric with the fan, thereby ensuring a uniform gap between the fan and the wind shield.

[0012] Furthermore, the limiting column has an L-shaped structure, the front end of the limiting column is conical, and the middle part of the bottom end of the limiting column is a hollow structure; this can facilitate the nesting of the expansion water tank outside the limiting column, and the middle part of the bottom end of the limiting column is a hollow structure, which can reduce casting defects while saving materials and reducing weight.

[0013] Furthermore, the fixing bracket and the limiting column are arranged at intervals, and the length direction of the fixing bracket is parallel to the extension direction of the limiting column; thereby, space can be provided for the installation of the expansion water tank.

[0014] Furthermore, the overall structure of the fixed bracket is a dam-type structure, thereby improving the structural strength of the fixed bracket.

[0015] Furthermore, the fixing bracket is provided with reinforcing ribs, which can further enhance the structural strength.

[0016] Furthermore, two expansion tank mounting holes are provided on the fixing bracket, and the expansion tank mounting nuts are embedded in the expansion tank mounting holes; thus, the fixing bracket has two mounting points, which, in conjunction with the limiting columns, can present a triangular fixing method, which is convenient to install and has a stable structure.

[0017] It can be seen from the above technical solutions that the present invention has at least the following technical effects or advantages:

[0018] 1. Because the transition ring is equipped with a limit post and a fixed bracket, the limit post can be placed in the water tank mounting hole of the expansion tank, and the fixed bracket can be connected to the expansion tank. Therefore, the wind shield and the expansion tank bracket can be integrated, thereby shortening the cooling pipe length and reducing the amount of coolant to be added. At the same time, the number of parts is reduced, the production efficiency is improved, and the cost and weight are greatly reduced;

[0019] 2. The triangular fixing structure of the expansion tank improves the stability of the overall installation; at the same time, the utility model can meet the strength requirements while effectively reducing the overall weight by reasonably arranging the structural direction, setting up a weight-reducing structure and a criss-crossing reinforcing rib structure, and making its lightweight effect significant, with good practicality and easy implementation.

[0025] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of this patent, other embodiments obtained by ordinary technicians in this field without making creative work are all within the scope of protection of this patent.

[0026] The utility model discloses a combined wind shield for a top-mounted expansion water tank of a light truck. Figure 1As shown, it comprises a base plate 1, a transition ring 2, a wind shield 3, a limiting post 4, and a fixing bracket 5. The base plate 1 and wind shield 3 are connected via the transition ring 2, and the limiting post 4 and fixing bracket 5 are both fixed to the transition ring 2. The limiting post 4 can be nested with the expansion tank to achieve connection with the expansion tank. The fixing bracket 5 is pre-embedded with an expansion tank mounting nut. During assembly, bolts are passed through the corresponding parts of the expansion tank and then engage with the expansion tank mounting nut to secure the expansion tank to the device, ensuring the stability and reliability of the entire structure.

[0027] In this embodiment, the base plate 1 is hollow in the middle, providing a channel for hot air to flow through the radiator. Its inner boundary is larger than the radiator core to maximize the radiator's heat dissipation capacity. Furthermore, a notch 6 is provided in the base plate 1 to ensure installation space for the radiator's water inlet pipe. A radiator mounting hole 7 is also provided in the base plate 1. Bosses are provided around the perimeter of the hole to prevent stress concentration. Furthermore, the oblong shape of the hole 7 allows for adjustment of the vertical position of the wind shield 3 relative to the fan, ensuring a uniform gap between the fan and the wind shield 3.

[0028] In this embodiment, the transition ring 2 is connected to the base plate 1 via a smooth transition surface, thereby preventing eddy currents and noise, maximizing the heat dissipation performance of the radiator. The wind shield 3 is a circular ring, providing the necessary clearance for the fan's circular rotation, and its center is concentric with the fan.

[0029] In this implementation, if Figure 1 As shown, the limiting post 4 is an L-shaped structure, integrally injection-molded onto the transition ring 2. The front end of the limiting post 4 is tapered to facilitate nesting the expansion tank within it. Furthermore, the bottom center of the limiting post 4 is hollow, thereby reducing casting defects while conserving material and reducing weight.

[0030] In this embodiment, the fixing bracket 5 is spaced apart from the limiting post 4, and its length is parallel to the extension direction of the limiting post 4, thereby providing space for the expansion tank to be installed. Specifically, the fixing bracket 5 defines two expansion tank mounting holes 8, into which the expansion tank mounting nuts are inserted. This provides two mounting points on the fixing bracket 5, forming a triangular fixing arrangement with the limiting post 4, making installation more convenient and the structure more stable.

[0031] More specifically, the fixed bracket 5 is integrally fixed to the transition ring 2 and the wind shield 3. The fixed bracket 5 has a dam-like structure, i.e., a wide lower side and a narrow upper side, which enhances the structural strength of the fixed bracket 5. Reinforcing ribs are also provided on both sides of the fixed bracket 5 to strengthen the connection between the fixed bracket 5, the transition ring 2, and the wind shield 3, thereby increasing local strength and reducing material usage.
