Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0037] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0038] The following is for reference. Figures 1-3The air intake protection structure 100 according to an embodiment of the present utility model can effectively block foreign objects such as rain, snow, branches, and leaves while ensuring smooth air intake. This effectively prevents the air intake 11 from being blocked, ensures that the air intake 11 can obtain clean air, reduces the risk of insufficient or no air intake of the vehicle equipment, and thus ensures the normal operation of the equipment.

[0039] like Figures 1-3 As shown, an intake protection structure 100 according to one embodiment of the present invention includes: a protective outer shell 1 and a protective inner cover 2. The intake protection structure 100 of the present invention can be installed on the top or side of a vehicle.

[0040] The protective shell 1 serves as an external protective layer, primarily resisting impurities and pollutants from the external environment, while also providing structural support to ensure the overall structural stability of the air intake protection structure 100. The protective shell 1 has an air inlet 11 and a connection port 12. The connection port 12 is used to connect to the air intake pipe 3. That is, the air inlet 11 can be located on one side of the protective shell 1 to ensure that air can smoothly enter the interior of the protective shell 1 through the air inlet 11, while the connection port 12 can be located on the other side of the protective shell 1 to ensure that the air entering from the air inlet 11 can continue to enter the air intake pipe 3.

[0041] Furthermore, a protective inner cover 2 is provided, which is installed inside the protective outer shell 1 and is distributed opposite to the connection port 12. An air intake gap 41 is formed between the protective inner cover 2 and the protective outer shell 1, and the air intake gap 41 connects the air intake port 11 and the connection port 12.

[0042] Specifically, the inner protective cover 2 is installed inside the outer protective shell 1, providing further filtration and protection. The inner protective cover 2 is positioned opposite the connection port 12, effectively blocking external impurities from directly entering the intake pipe 3 and causing blockage. A certain distance is maintained between the inner protective cover 2 and the outer protective shell 1 to form an intake gap 41, which connects the intake port 11 and the connection port 12. Air flowing in from the intake port 11 can pass through the intake gap 41 to the connection port 12 and enter the inner area of ​​the inner protective cover 2. During this process, larger impurities are blocked outside the intake gap 41, preventing blockage of the intake port 11. The air then flows into the intake pipe 3, providing clean air to the engine, air compressor, heating system, or other equipment requiring air, ensuring the normal operation of the equipment.

[0043] Therefore, due to the protection of the inner cover 2 and the air intake gap 41 formed between the inner cover 2 and the outer cover 1, the air intake is ensured to be smooth while effectively blocking external foreign objects such as rain, snow, branches, and leaves. This solves the problem of snow accumulation blocking the air intake 11 in high-altitude and cold regions, and prevents external foreign objects such as branches and leaves from blocking the air intake 11. This ensures that the air intake 11 can obtain clean air and reduces the risk of insufficient or no air intake for the vehicle equipment, thus ensuring the normal operation of the equipment.

[0044] According to the air intake protection structure 100 of this utility model embodiment, by setting a protective inner cover 2 installed inside the protective outer shell 1, and forming an air intake gap 41 between the protective inner cover 2 and the protective outer shell 1, it can effectively block foreign objects such as rain, snow, branches, and leaves while ensuring smooth air intake, thereby effectively preventing the air intake 11 from being blocked, ensuring that the air intake 11 can obtain clean air, reducing the risk of insufficient air intake or inability to obtain air for the vehicle equipment, and thus ensuring the normal operation of the equipment.

[0045] In some embodiments, such as Figure 2 and Figure 3 As shown, the protective housing 1 includes an outer ring portion 13 and an outer bottom wall 14. The outer bottom wall 14 is connected to the outer ring portion 13 and together defines an outer guide cavity 15 open on one side, as shown. Figure 3 As shown in the left-right direction, the outer bottom wall 14 is connected to the left side of the outer ring 13 to jointly define the open outer guide cavity 15 on the right side. That is, the outer guide cavity 15 is a cavity inside the protective shell 1, used to guide air from the air inlet 11 to the connection port 12. The outer guide cavity 15 has a large space, which allows the air to flow smoothly and reduces the formation of eddies and turbulence.

[0046] Furthermore, such as Figure 2 and Figure 3 As shown, the connection port 12 is located on and penetrates the outer bottom wall 14, and the open side of the outer guide cavity 15 is as follows: Figure 3 The right side of the structure is the air inlet 11, and the protective inner cover 2 is installed in the outer guide cavity 15. In this way, fresh air from the outside environment can enter from the open side of the outer guide cavity 15, i.e., the air inlet 11, under the guidance of the outer guide cavity 15, and flow through the air inlet gap 41 into the outer guide cavity 15, and then flow into the air inlet pipe 3 at the connection port 12.

[0047] Thus, the outer guide cavity 15, defined by the outer ring 13 and the outer bottom wall 14, provides a smooth flow channel for air. At the same time, the protective inner cover 2 inside the outer guide cavity 15 can prevent external impurities from blocking the air intake channel, thereby enhancing the protective function of the air intake protection structure 100.

[0048] In some embodiments, such as Figure 2 and Figure 3 As shown, the protective inner cover 2 includes an inner ring portion 21 and an inner bottom wall 22. The inner bottom wall 22 is connected to the inner ring portion 21 and together defines the inner guide cavity 23. That is, the interior of the protective inner cover 2 is a cavity. The inner guide cavity 23 is used to further guide the airflow to the connection port 12. The inner guide cavity 23 is open towards the connection port 12, i.e. Figure 3 As shown in the left-right direction, the inner guide cavity 23 is open to the left so that the inner bottom wall 22 is directly opposite the connection port 12 on the left side. This ensures that air flows smoothly from the inner guide cavity 23 into the air intake pipe 3.

[0049] Furthermore, the intake gap 41 is formed between the inner ring 21 and the outer ring 13, so that the inner guide cavity 23 is connected to the outer guide cavity 15. After the air enters the outer guide cavity 1 through the intake gap 41 from the open side of the outer guide cavity 15, i.e. the air inlet 11, it can continue to flow into the inner guide cavity 23, and then continue to flow into the intake pipe 3 under the guidance of the inner guide cavity 23.

[0050] Since both the inner ring 21 and the outer ring 13 are annular, the air intake gap 41 formed between the inner ring 21 and the outer ring 13 is also annular. Thus, an annular gap is formed, which means that air can enter along the circumference of the annular gap, improving the air intake efficiency and raising the air intake position so that it can enter from above the annular gap, thereby solving the problem of snow accumulation blocking the air intake in cold regions.

[0051] Thus, through the combined action of the outer guide cavity 15 and the inner guide cavity 23, the airflow direction is effectively guided, allowing it to flow into the intake pipe 3 efficiently and quickly. At the same time, the protective inner cover 2 effectively filters the air, preventing external impurities from entering the intake protection structure 100, thereby ensuring the cleanliness of the air.

[0052] In some embodiments, the outer bottom wall 14 is provided with an annular flange 141, and the connection port 12 is formed in the annular flange 141.

[0053] Specifically, such as Figure 3As shown, the outer bottom wall 14 is provided with an annular flange 141. The shape of the annular flange 141 matches the shape of the air intake pipe 3. A connection port 12 is formed inside the annular flange 141. The inner diameter of the connection port 12 matches the outer radial dimension of the air intake pipe 3. In this way, the air intake pipe 3 can pass smoothly through the connection port 12 to connect with the outer ring 13. At the same time, the annular flange 141 can be tightly attached to the outer peripheral wall of the air intake pipe 3. Thus, through the support and positioning of the annular flange 141, a tight and reliable connection between the air intake pipe 3 and the protective shell 1 is achieved. This not only improves the sealing performance of the air intake protection structure 100 and prevents air leakage from the connection port 12, but also enhances the structural strength of the outer bottom wall 14, ensuring the protective function of the protective shell 1 and preventing it from falling off. In actual design, the annular flange 141 can be connected to the air intake pipe 3 by welding.

[0054] In some embodiments, such as Figure 3 As shown, the annular flange 141 protrudes into the outer guide cavity 15 relative to the outer bottom wall 14. This allows the annular flange 141 to be located inside the outer guide cavity 15, preventing external environment from eroding or damaging the annular flange 141, thereby extending the service life of the protective shell 1.

[0055] In some embodiments, such as Figure 2 and Figure 3 As shown, the outer diameter of the inner ring 21 gradually increases from the inner bottom wall 22 toward the connection port 12, that is, corresponding to Figure 3 In the left-right direction, the diameter of the inner ring 21 gradually increases from right to left. This can better guide the airflow and reduce the resistance in the inner guide cavity 23, allowing more air in the inner guide cavity 23 to flow easily and smoothly into the intake pipe 3, thereby improving the intake efficiency. At the same time, it can make the connection port 12 smoothly connect with the protective inner cover 2, avoiding interference between the protective inner cover 2 and the intake pipe 3 or the connection port 12.

[0056] In other embodiments, such as Figure 2 and Figure 3 As shown, the outer diameter of the outer ring 13 gradually increases from the outer bottom wall 14 toward the connection port 12, that is, corresponding to Figure 3 In the left-right direction, the diameter of the outer ring 13 gradually increases from left to right, thereby increasing the size of the air inlet 11 and allowing more air to flow more smoothly from the air inlet 11 into the air intake protection structure 100, thereby improving the air intake volume and air intake efficiency.

[0057] In addition, such as Figure 3As shown, since the outer diameter of the outer ring 13 gradually increases from the outer bottom wall 14 toward the connection port 12, the inner wall of the outer ring 13 is inclined. After the air passes through the air intake gap 41, it can be guided to flow quickly downward along the inner wall into the inner guide cavity 23. Then, under the action of the inner guide cavity 23, it can continue to flow into the air intake pipe 3.

[0058] In some embodiments, such as Figure 2 and Figure 3 As shown, the inner protective cover 2 and the outer protective cover 1 are spaced apart, meaning that the inner protective cover 2 and the outer protective cover 1 do not contact each other. This facilitates the formation of an air intake gap 41, ensuring that air flows smoothly through the air intake gap 41 into the interior of the air intake protection structure 100.

[0059] The inner protective cover 2 and the outer protective cover 1 are connected by a connector 5 to ensure a stable and reliable connection between the inner protective cover 2 and the outer protective cover 1, enhance the overall structural strength of the intake protection structure 100, ensure that the intake gap 41 is stable, and prevent the inner protective cover 2 from loosening or falling off, thereby affecting the intake process.

[0060] In some embodiments, there are multiple connectors 5, that is, the number of connectors 5 can be set to two, three, four or even more. Setting multiple connectors 5 can enable the protective shell 1 and the protective inner cover 2 to be connected at multiple connection points through multiple connectors 5, thereby further improving the connection stability and reliability between the protective shell 1 and the protective inner cover 2.

[0061] Multiple connectors 5 are spaced apart around the inner protective cover 2. This allows the connectors 5 to be evenly spaced along the circumference of the inner protective cover 2 to connect with the outer protective cover 1, thereby ensuring that the connectors 5 can transmit force and load evenly and prevent the inner protective cover 2 or the outer protective cover 1 from deforming or being damaged due to excessive local force.

[0062] Specifically, such as Figure 1 As shown, three connectors 5 are provided, but four, five, or other quantities can also be used. The three connectors 5 are evenly spaced around the protective inner cover 2 to ensure a stable and reliable connection between the protective outer shell 1 and the protective inner cover 2. In actual design, the connectors 5 can be constructed as connecting plates, bolts, screws, etc., and can be flexibly set according to the actual situation.

[0063] In some embodiments, such as Figure 3 As shown, the connector 5 includes a connecting body portion 51 and a connecting flange portion 52. The connecting body portion 51 is used to connect with the inner protective cover 2, and the connecting flange portion 52 is used to connect with the outer protective cover 1, thereby realizing the connection between the inner protective cover 2 and the outer protective cover 1. The connecting flange portion 52 is bent and connected to the connecting body portion 51 to form a shape as shown in the figure. Figure 3The “L”-shaped structure shown means that the connecting body part 51 and the connecting flange part 52 are connected by a 90-degree bend. Of course, they can also be connected by bends at other angles. For example, the connecting body part 51 and the connecting flange part 52 can be connected by a 70-degree bend or a 100-degree bend. The structure can be flexibly set according to the actual situation.

[0064] Furthermore, the connecting main body 51 is connected to the outer surface of the protective inner cover 2, and the connecting flange 52 is connected to the inner surface of the protective outer shell 1. Specifically, as shown... Figure 3 As shown, the connecting body 51 is fitted to the outer peripheral wall of the inner ring 21, and the connecting flange 52 is fitted to the inner peripheral wall of the outer ring 13. This increases the contact area between the connecting body 51 and the protective inner cover 2, and the contact area between the connecting flange 52 and the protective outer shell 1, thereby achieving a reliable connection between the connector 5 and the protective inner cover 2 and the protective outer shell 1, preventing the connector 5 from separating from the protective inner cover 2 and the protective outer shell 1, and further improving the connection stability and reliability of the protective inner cover 2 and the protective outer shell 1, and enhancing the overall structural strength of the intake protection structure 100.

[0065] In some embodiments, the air intake protection structure 100 further includes a filter 6, which is installed at the air intake 11.

[0066] Therefore, the air can be initially filtered before passing through the air inlet 11, filtering out larger impurities and pollutants, and blocking larger foreign objects such as leaves and foliage from the outside, thus preventing blockage of the air inlet 11, thereby further improving the cleanliness and smoothness of the air flow.

[0067] In some embodiments, such as Figure 1 As shown, the filter element 6 is constructed as a filter screen. The filter screen and the protective inner cover 2 are distributed opposite to the surface of the connection port 12. That is, the filter screen covers the outside of the protective inner cover 2. Thus, the filter screen can initially block large foreign objects such as leaves and branches. The protective inner cover 2 then blocks them from the inside to prevent rain and snow from clogging the air inlet 11.

[0068] Thus, through the dual blocking effect of the filter element 6 and the protective inner cover 2, the filtering and protection function of the air intake protection structure 100 is greatly improved, and the effect of preventing blockage of the air intake 11 is enhanced.

[0069] In some embodiments, such as Figure 3As shown, the filter element 6 includes a filter body 61 and a mounting flange 62. The filter body 61 is circular and is adapted to the shape and size of the air inlet 11. The mounting flange 62 extends and bends along the periphery of the filter body 61. Thus, the filter body 61 can be directly opposite the air inlet 11 to cover the air inlet 11 and block foreign objects. The filter body 61 is provided with multiple filter holes, and air can enter the outer guide cavity 15 through the filter holes.

[0070] The flanged part 62 is connected to the protective shell 1, specifically, as shown in... Figure 3 As shown, the mounting flange 62 extends toward the outer ring 13 to fit and connect with the outer peripheral wall of the outer ring 13. Thus, the filter element 6 is covered on the air inlet 11 side of the protective shell 1. The mounting flange 62 enables a reliable connection between the filter element 6 and the protective shell 1, preventing the filter element 6 from loosening or falling off and affecting the filtration effect.

[0071] In actual design, the mounting flange 62 and the protective shell 1 can be connected by other connection methods such as welding, bolting, and snap-fit. Among them, the detachable connection method facilitates the installation and removal of the filter element 6. When the filter holes of the filter element 6 are blocked, it can be easily and quickly removed for cleaning.

[0072] In some embodiments, such as Figure 3 As shown, the air intake gap 41 is distributed around the outer periphery of the protective inner cover 2, that is, the air intake gap 41 is constructed as a ring. This ensures that air can flow into the air intake protection structure 100 evenly through the air intake gap 41, reducing the formation of eddies and turbulence, thereby improving air intake efficiency. It also allows air to flow into the air intake protection structure 100 through the air intake gap 41 in all circumferential directions. In this way, air can enter the air intake protection structure 100 through the upper air intake gap 41, thereby raising the air intake position and solving the problem of snow accumulation blocking the air intake 11 in high-altitude and cold regions.

[0073] In some embodiments, the inner protective cover 2 is provided with a heating element, which can generate heat to increase the temperature of the inner protective cover 2. Thus, in rainy or snowy weather, when the outdoor temperature is low, the inner protective cover 2 can be heated by the heating element to melt the snow, thereby further preventing rain and snow from blocking the air inlet 11, ensuring that the air inlet 11 and the air inlet gap 41 are unobstructed, and realizing smooth airflow.

[0074] In the actual design, the protective inner cover 2 can be made of metal to facilitate heat conduction. The heating element can be constructed as a resistance wire. The resistance wire can be laid on the inner bottom wall 22 of the protective inner cover 2 facing the connection port 12. Then, the outdoor temperature is detected by a temperature sensor. When the temperature sensor detects that the outdoor temperature is lower than the preset value (such as zero degrees Celsius), the resistance wire can be energized to generate heat. The heat is conducted to the protective inner cover 2 to increase the temperature of the protective inner cover 2, thereby achieving snow melting.

[0075] This utility model also proposes an air intake pipe assembly.

[0076] The intake pipe assembly according to the present utility model includes an intake pipe 3 and an intake protection structure 100 of any of the above embodiments, wherein the intake pipe 3 is connected to the connection port 12.

[0077] Specifically, such as Figures 1-3 As shown, the intake pipe 3 is connected to the connector 12, thereby achieving communication between the intake pipe 3 and the intake protection structure 100. This ensures that air flows smoothly through the intake protection structure 100 into the intake pipe 3, guaranteeing the smoothness of the intake process, and then flows to the intake system of the engine or other equipment for use. For example, Figure 3 As shown, the intake pipe 3 is shaped like a bend, which facilitates connection with the intake protection structure 100 so that the intake protection structure 100 can be installed on the top or side of the vehicle.

[0078] In some embodiments, such as Figure 3 As shown, the intake pipe 3 is provided with a pipe inlet 31, through which air can flow into the intake pipe 3. At least a portion of the pipe inlet 31 extends into the protective inner cover 2 and communicates with the intake gap 41. That is, the pipe inlet 31 is simultaneously connected with the inner guide cavity 23 and the intake gap 41. In this way, after the air flows into the outer guide cavity 15 through the intake gap 41, it can continue to flow into the inner guide cavity 23, and then enter the intake pipe 3 through the pipe inlet 31, and then flow to other equipment such as the engine, air compressor, and heating system to ensure the normal operation of the equipment.

[0079] This utility model also proposes a vehicle.

[0080] The vehicle according to the present utility model is provided with an intake protection structure 100 of any of the above embodiments and / or an intake pipe assembly of any of the above embodiments.

[0081] The vehicle in this embodiment of the utility model can be any vehicle such as an electric bus, electric car, hybrid vehicle, off-road vehicle, truck, or van.

[0082] By installing a protective inner cover 2 inside the protective outer shell 1, and forming an air intake gap 41 between the protective inner cover 2 and the protective outer shell 1, the air intake can be ensured smoothly while effectively blocking foreign objects such as rain, snow, branches, and leaves.
