Description

Technical Field

[0001] The present invention relates to the technical field of air guide covers, and in particular to an air guide cover for a cooling fan of a motorcycle engine and a motorcycle. Background Art

[0002] When a motorcycle engine is working, it usually generates a lot of heat, causing the temperature of the engine to rise. Excessive temperature will not only greatly reduce the working efficiency of the engine, but also easily cause damage to the engine and other components connected to the engine. Therefore, in the design and manufacture of motorcycle engines, it is often necessary to make the engine have good heat dissipation.

[0003] Currently, the common heat dissipation methods for motorcycle engines on the market are divided into air cooling, oil cooling, water cooling, and combined cooling. Among them, the forced air cooling method in the air cooling method is the cooling method adopted by most models. From the perspective of the engine structure, this cooling method has a relatively simple structure, low cost, and good heat dissipation effect. It has an additional cooling fan connected to the engine and driven by the engine compared with the natural air cooling method. The cooling fan generates a component force to forcibly cool the engine at the moment when the engine starts.

[0004] To facilitate the positioning of the wires led out from the stator of the engine and electrically connected to the control circuit board of the motorcycle, the air guide cover for the cooling fan of the motorcycle engine is provided with a wire pressing plate, and the engine housing is provided with a groove for the wires to pass through and cooperate with the wire pressing plate to jointly press the wires. However, due to structural design problems, the wire pressing plate will cause the air guide cover to deform when pressing the wires, resulting in interference between the air guide cover and the fan blade structure located inside, thereby causing noise and even affecting the normal operation of the fan blade structure. Summary of the Invention

[0005] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide an air guide cover for a cooling fan of a motorcycle engine, which can prevent deformation to avoid interference with the fan blade structure provided inside; the purpose of the present invention is also to provide a motorcycle, which can reduce noise and ensure the normal operation of the engine cooling fan.

[0006] The purpose of the present invention is achieved by adopting the following technical solutions:

[0007] The present invention provides an air guide cover for a cooling fan of a motorcycle engine, including:

[0008] A cover body, on which there is an air duct that penetrates through its head and tail ends and allows a fan blade structure to penetrate into it. The cover body includes an annular bottom plate at its head end, an annular top plate at its tail end, and an annular side plate erected between the outer sides of the annular bottom plate and the annular top plate and connecting the annular bottom plate and the annular top plate together. The annular bottom plate, the annular top plate, and the annular side plate are all arranged around the air duct;

[0009] A wire pressing plate, which is located at the head end of the cover body and erected on the outer end face of the annular bottom plate;

[0010] A first support member, which is located below the wire pressing plate. One end of the first support member is connected to the inner end face of the annular bottom plate, and the other end of the first support member is connected to the inner end face of the annular top plate opposite to the annular bottom plate.

[0011] Further, the first support member is located directly below the wire pressing plate.

[0012] Further, the number of the first support members is at least two, and each of the first support members is arranged one by one along the length direction of the wire pressing plate.

[0013] Further, the number of the first support members is two.

[0014] Further, the first support member is also connected to the inner side surface of the annular side plate.

[0015] Further, the annular bottom plate and the annular top plate are arranged in parallel and are both perpendicular to the first support member.

[0016] Further, a second support member is provided between the wire pressing plate and the annular bottom plate, and the second support member can prevent the wire pressing plate from bending and deforming when the wire pressing plate presses the wire.

[0017] Further, at least two second support members are provided, and each of the second support members is arranged one by one along the length direction of the wire pressing plate.

[0018] Further, the second support member is a triangular structure with an outer diameter gradually increasing from top to bottom.

[0019] The present invention also provides a motorcycle, which includes a motorcycle body and the above-mentioned air guide cover for a motorcycle engine radiator fan;

[0020] An engine connected to a crankshaft and driven by the crankshaft is provided on the motorcycle body, and a fan blade structure connected to a rotor of the engine and driven by the rotor of the engine is provided. A groove through which a wire electrically connected to a stator of the engine can pass out is provided on a box body of the engine;

[0021] The cover body is arranged on the box body of the engine. The air duct accommodates the fan blade structure. The wire pressing plate faces the groove and together with the groove presses the part of the wire located in the groove.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] For the air guide cover of the motorcycle engine radiator fan of the present invention, by arranging a first support member below the wire pressing plate, the first support member can effectively support the part of the annular bottom plate located below the wire pressing plate, strengthening the structural strength of the part of the annular bottom plate located below the wire pressing plate. At the same time, it also strengthens the structural strength of the part of the cover body located below the wire pressing plate. Therefore, when the wire pressing plate presses the wire, the pressure of the wire pressing plate can be transmitted to the first support member and the annular top plate, playing a role in dispersing the pressure of the wire pressing plate, avoiding the pressure of the wire pressing plate acting concentratedly on the annular bottom plate and causing the annular bottom plate to deform, thereby avoiding interference between the air guide cover and the fan blade structure located in the air duct, avoiding noise, and at the same time ensuring the normal operation of the fan blade structure.

[0024] For the motorcycle of the present invention, due to adopting the above air guide cover of the motorcycle engine radiator fan, it can avoid interference between the air guide cover and the fan blade structure located in its air duct, thus helping to reduce noise and at the same time ensuring the normal operation of the fan blade structure.

[0030] Next, in combination with the accompanying drawings and specific embodiments, the present invention will be further described. It should be noted that, on the premise of non-conflict, any combination of the following-described embodiments or technical features can form a new embodiment.

[0031] Refer to Figures 1 - 2 , which shows a wind guide cover for a cooling fan of a motorcycle engine according to a preferred embodiment of the present invention, used for guiding the air flow of the fan blade structure in the cooling fan. It includes: a cover body 10, on which there is a wind channel 14 that penetrates through its head and tail ends and allows the fan blade structure to penetrate into it. The cover body 10 includes an annular bottom plate 11 at its head end, an annular top plate 12 at its tail end, and an annular side plate 13 erected between the outer sides of the annular bottom plate 11 and the annular top plate 12 to connect the annular bottom plate 11 and the annular top plate 12 together. The annular bottom plate 11, the annular top plate 12, and the annular side plate 13 are all arranged around the wind channel 14; a wire pressing plate 20, which is located at the head end of the cover body 10 and erected on the outer end face of the annular bottom plate 11, used to jointly press the part of the wire 60 located in the groove on the box body 50 of the engine; a first support member 30, which is located below the wire pressing plate 20. One end of the first support member 30 is connected to the inner end face of the annular bottom plate 11, and the other end of the first support member 30 is connected to the inner end face of the annular top plate 12 opposite to the annular bottom plate 11.

[0032] For the wind guide cover for a cooling fan of a motorcycle engine of the present invention, by arranging the first support member 30 below the wire pressing plate 20, the first support member 30 can effectively support the part of the annular bottom plate 11 below the wire pressing plate 20, strengthening the structural strength of the part of the annular bottom plate 11 below the wire pressing plate 20. At the same time, it also strengthens the structural strength of the part of the cover body 10 below the wire pressing plate 20. Therefore, when the wire pressing plate 20 presses the wire, the pressure of the wire pressing plate 20 can be transmitted to the first support member 30 and the annular top plate 12, playing a role in dispersing the pressure of the wire pressing plate 20, avoiding the pressure of the wire pressing plate 20 being concentrated on the annular bottom plate 11 and causing the annular bottom plate 11 to deform, thereby avoiding interference between this wind guide cover and the fan blade structure located in the wind channel 14, avoiding noise, and ensuring that the fan blade structure can operate normally.

[0033] Refer to Figure 1 , in this embodiment, the first support member 30 is located directly below the wire pressing plate 20. In this way, it can effectively support the part of the annular bottom plate 11 directly below the wire pressing plate 20 and strengthen the structural strength of this part, thus being able to reliably avoid deformation of the part of the annular bottom plate 11 below the wire pressing plate 20, and the anti-deformation reliability is higher.

[0034] In this embodiment, the number of the first support members 30 is two, and each first support member 30 is arranged one by one along the length direction of the wire pressing plate 20. In this way, while the part of the annular bottom plate 11 below the wire pressing plate 20 can be reliably supported, since the number of the first support members 30 is not large, the structure is relatively simple, which is more convenient for manufacturing the cover body 10.

[0035] In other embodiments, the number of the first support members 30 can be one or three or more. When it is one, the cross-sectional area of the first support member 30 can be close to or larger than the lateral area of the wire pressing plate 20, so as to be able to reliably support the part of the annular bottom plate 11 below the wire pressing plate 20; when it is three or more, each first support member 30 can be arranged one by one along the length direction of the wire pressing plate 20.

[0036] To further strengthen the structural strength of the part of the annular bottom plate 11 below the wire pressing plate 20, in other embodiments, the first support member 30 is also connected to the inner side surface of the annular side plate 13.

[0037] In this embodiment, the annular bottom plate 11 and the annular top plate 12 are arranged in parallel and both are perpendicular to the first support member 30. In this way, it is more helpful to disperse the pressure of the wire pressing plate 20, so the reliability of anti-deformation is higher.

[0038] See Figure 1 and Figure 2 , in this embodiment, a second support member 40 is provided between the wire pressing plate 20 and the annular bottom plate 11. The second support member 40 can prevent the wire pressing plate 20 from bending and deforming when the wire pressing plate 20 presses the wire, so that the wire pressing plate 20 can reliably press the wire.

[0039] In this embodiment, there are two second support members 40, and each second support member 40 is arranged one by one along the length direction of the wire pressing plate 20. In this way, the wire pressing plate 20 can be reliably supported, and the anti-deformation performance of the wire pressing plate 20 can be further improved.

[0040] In other embodiments, the first support member 30 can be provided with one or three or more, and those skilled in the art can set it according to needs, and are not limited thereto.

[0041] See Figure 2 , in this embodiment, the second support member 40 is a triangular structure with an outer diameter gradually increasing from top to bottom. This triangular structure has better structural stability, can reliably support the wire pressing plate 20 and strengthen the structural strength of the wire pressing plate 20, so that the anti-deformation performance of the wire pressing plate 20 is better.

[0042] See Figures 3 - 4, the present invention also provides a motorcycle, comprising a motorcycle body and the above-mentioned air guide cover for the motorcycle engine cooling fan; wherein, an engine connected to and driven by a crankshaft and a fan blade structure connected to and driven by a rotor of the engine are provided on the motorcycle body, a groove through which a wire 60 electrically connected to a stator of the engine can pass is provided on a housing 50 of the engine; a cover body 10 is arranged on the housing 50 of the engine, an air duct 14 accommodates the fan blade structure and allows the fan blade structure to rotate therein, a wire pressing plate 20 faces the groove and jointly presses the part of the wire 60 located in the groove with the groove to position the wire 60.

[0043] For the motorcycle of the present invention, due to the adoption of the above-mentioned air guide cover for the motorcycle engine cooling fan, interference between the air guide cover and the fan blade structure located in its air duct 14 can be avoided, thus helping to reduce noise and ensuring the normal operation of the fan blade structure at the same time.

[0044] See Figures 3 - 4 , in this embodiment, to avoid pressing damage to the wire 60, a rubber plug 70 is sleeved on the part of the wire 60 located in the groove, the rubber plug 70 is inserted into the groove and is adapted to the groove, and the wire pressing plate 20 presses the rubber plug 70 to press the part of the wire 60 located in the groove in the groove.

[0045] The above-mentioned embodiments are only the preferred embodiments of the present invention, and the scope of protection of the present invention cannot be limited thereby. Any non-substantive changes and substitutions made by those skilled in the art based on the present invention belong to the scope of protection required by the present invention.
