Description

Technical Field

[0001] The utility model belongs to the technical field of motorcycles, and in particular relates to a motorcycle cylinder head cover with increased operating space. Background Art

[0002] A motorcycle cylinder head, also known as a cylinder head or cylinder cover, is a crucial component of a motorcycle engine. It typically features a cooling water jacket (for water-cooled engines), circulating water to cool high-temperature components such as the combustion chamber. It also features camshaft bearing holes (for overhead camshaft engines) for mounting the camshaft. Cylinder heads are typically cast from gray cast iron or alloy cast iron. In recent years, aluminum alloy cylinder head covers have become increasingly popular due to their excellent thermal conductivity, which helps improve compression ratios.

[0003] Currently, existing motorcycle cylinder head covers, once installed on the vehicle, are extremely difficult to remove due to the extremely limited operating space between the head cover and the frame. This, in turn, makes maintenance difficult and seriously affects maintenance efficiency. Therefore, to address this issue, we designed a motorcycle cylinder head cover that increases the operating space. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a motorcycle cylinder head cover with increased operating space. This motorcycle cylinder head cover with increased operating space solves the technical problem that, once installed on a motorcycle, the cylinder head cover is extremely difficult to remove due to the extremely limited operating space between the head cover and the frame, which in turn makes maintenance difficult and seriously affects maintenance efficiency.

[0005] To achieve the above-mentioned object, according to an embodiment of a first aspect of the present utility model, a motorcycle cylinder head cover with increased operating space is provided, comprising a cover body;

[0006] Wherein, the cover body includes a connecting section and a protective section;

[0007] The outer side of the protective section of the cover body is provided with a frame avoidance groove, which is designed to be inclined;

[0008] A reinforcement layer and a noise reduction layer are provided in the protective section of the cover body. The reinforcement layer is wrapped on the noise reduction layer. The noise reduction layer is filled with sound-absorbing material. A plurality of reinforcement ribs are provided in the reinforcement layer.

[0009] A further improvement is that a circle of installation limiting grooves is provided at the inner edge of the connecting section of the cover body, and the installation limiting grooves are used for positioning and installing the sealing ring.

[0010] A further improvement is that the outer wall of the protective section of the cover is provided with a coating layer, and the coating layer includes an anti-oxidation coating layer and a corrosion-resistant coating layer.

[0011] A further improvement is that each of the reinforcing ribs is U-shaped and is arranged to fit the inner wall of the reinforcing layer.

[0012] A further improvement is that the sound-absorbing material in the noise reduction layer is polyester fiber cotton.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] (1) The design of the frame avoidance groove of the utility model increases the operating space during maintenance, improves the efficiency of maintenance, and increases the adaptability between different models;

[0015] (2) The present invention provides a composite structure of a reinforcement layer and a noise reduction layer inside the protective section of the cover. The reinforcement layer is tightly wrapped around the outside of the noise reduction layer, while the noise reduction layer is filled with high-efficiency polyester fiber cotton sound-absorbing material. This configuration can effectively absorb the noise generated during engine operation and significantly reduce the level of noise transmission. Multiple U-shaped reinforcement ribs are cleverly arranged inside the reinforcement layer. They are tightly attached to the inner wall of the reinforcement layer, significantly enhancing the structural strength of the cylinder head cover and effectively resisting deformation caused by external force extrusion.

[0016] (3) The utility model also applies a special coating layer on the outer wall of the protective section, which is composed of an anti-oxidation coating layer and a corrosion-resistant coating layer. This double-layer coating design not only provides the cylinder head cover with excellent resistance to scratches, wear and erosion, but also effectively delays its aging process, thereby comprehensively extending the overall service life of the cylinder head cover.

[0023] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] like Figure 1 As shown, a motorcycle cylinder head cover with increased operating space includes a cover body 1, and the cover body 1 includes a connecting section 11 and a protective section 12;

[0025] The outer side of the protective section 12 of the cover body 1 is provided with an inclined frame avoidance groove 2, which is inclined downward from the middle of the protective section 12 to the edge. This design increases the operating space during maintenance and improves the efficiency of maintenance.

[0026] Specifically, as a preferred embodiment, a circle of mounting limit grooves 15 is provided at the inner edge of the connecting section 11 of the cover body 1, and the mounting limit grooves 15 are used to position and install the sealing ring;

[0027] like Figure 2 and Figure 4 As shown, this embodiment also provides an implementation scheme, which is as follows:

[0028] A reinforcement layer 101 and a noise reduction layer 102 are provided in the protection section 12 of the cover body 1, and the reinforcement layer 101 is wrapped on the noise reduction layer 102;

[0029] Specifically, the noise reduction layer 102 is filled with a sound-absorbing material made of polyester fiber cotton, which can effectively absorb the noise generated during engine operation and reduce the spread of noise; the reinforcement layer 101 is provided with a plurality of reinforcing ribs 13, each of which is U-shaped and fits the inner wall of the reinforcement layer 101. This design can increase the structural strength of the cylinder head cover and effectively resist deformation caused by external force.

[0030] like Figure 2 As shown, this embodiment also provides an implementation scheme, which is as follows:

[0031] The outer wall of the protective section 12 of the cover body 1 is provided with a coating layer 14, which includes an anti-oxidation coating layer 141 and a corrosion-resistant coating layer 142. This design can prevent the cylinder head cover from abnormal scratches, wear and erosion, and can effectively slow down its aging process, thereby extending the overall service life of the cylinder head cover.

[0032] like Figures 1 to 4 As shown, in this embodiment, the actual size of each component in the application document is selected and installed according to the actual needs of the cylinder head cover on site. In addition, it should be noted that the preparation process of the cylinder head cover of this embodiment is existing technology and the working principle is public.

[0033] It should be noted that this application document only addresses the shortcomings of existing motorcycle cylinder head covers. When the cylinder head cover is installed on the vehicle, the operating space between the head cover and the frame is extremely limited, making the removal process extremely difficult. This in turn makes maintenance difficult and seriously affects maintenance efficiency. It does not involve improvements in other aspects. The following is an introduction to the working principle of a motorcycle cylinder head cover with increased operating space:

[0034] The new design provides an inclined frame avoidance groove 2 on the cylinder head cover, which extends obliquely downward from the middle of the protection section 12 to the edge. This design expands the operating space during maintenance and significantly improves the efficiency of maintenance work.

[0035] Furthermore, a composite structure consisting of a reinforcement layer 101 and a noise-reduction layer 102 is positioned within the protective section 12 of the cover 1. The reinforcement layer 101 tightly wraps around the noise-reduction layer 102, which is filled with a highly effective polyester fiber cotton sound-absorbing material. This configuration effectively absorbs noise generated during engine operation, significantly reducing its transmission. Multiple U-shaped reinforcing ribs 13 are strategically positioned within the reinforcement layer 101, clinging to its inner wall. These ribs significantly enhance the structural strength of the cylinder head cover and effectively resist deformation caused by external forces.

[0036] Furthermore, the outer wall of the protective section 12 is coated with a special coating layer 14, which consists of an anti-oxidation coating layer 141 and a corrosion-resistant coating layer 142. This two-layer coating design not only provides the cylinder head cover with excellent resistance to scratches, wear, and erosion, but also effectively delays its aging process, thereby comprehensively extending the overall service life of the cylinder head cover.

[0037] The above embodiments are only used to illustrate the technical method of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
